    indoor playground
    Indoor children's playground can be a place for children to learn. Generally choose to open from a commercial area, it is relatively easy to get going in operation and operations, and does not involve complex content like inventory management, and incorporates a greater development prospect inside the national market.Equipment type Such as balloon property, ice and snow, and many others.,usually combined with your slide ball pool combination. This type of equipment is surely an essential part of the park. While being beloved by children, it can increase the play space of the park through the double-layer podium.Rotating swing toys For example coconut trees, big tennis ball trees, dolphin swings etc .. The height of this play equipment is in relation to 2. 8 meters, as well as colorful colors are the highlight belonging to the park.Climbing gear Just like animal forest, rotating planet earth, rotating rock climbing et cetera. This type of perform equipment exercises the courage and courage of the baby, and is most in-demand with young boys.Merry-go-round video games The most popular one of the little girls, they fulfilled their princess dreams.Waterbed type play equipment There are usually fish, tortoises, octopus and also other lifelike animals in the water. Every child is like visiting the beach and can lie within the water bed to study for years.Trampoline games The traditional trampoline is often a spring-loaded net structure, along with the new trampoline is a strong inflatable cushion. The former is suitable for children of the specific age who need to uncover stimulation, and the latter would work for children, so them to will not feel terrified while being stimulated.On top of that, indoor playgrounds are also used in children's treatment and rehabilitation training. Playground equipment (such because slides and large buzzers) are of great easily children's rehabilitation training. Your therapist also designed alternative features, such as great pedals to recreate this oversized bus pedals, which might become challenging for youngsters with mobility impairments. Furthermore, the playground has in addition designed and built an indoor climbing wall. When children exercise for the playground, they usually respond additional positively to treatment and may not even realize actually working hard to gain their goals.https://www.playground.com.cn/Indoor-Soft-Playground-pl87320.html 2021ld

    Melamine products
    Melamine cheap tableware belongs to substantial molecular polymer, and the monomers are formaldehyde as well as melamine. A 37% aqueous option of formaldehyde was used for that reaction, and the molar ratio with the two monomers of formaldehyde along with melamine was 2~3.Melamine cheap tableware, also known when imitation porcelain tableware, is traditional in fast food on account of its light weight, gorgeous appearance, low temperature resistance (you might put it directly in the refrigerator), boiling resistance (boiling in addition to boiling), pollution resistance, and also resistance to breakage. The food item industry and children's providing industry are deeply beloved by consumers and young children.How to choose tableware As a result of high price of melamine powder snow, some illegal businesses, around pursuit of profit, right use urea-formaldehyde molding powder snow as raw materials intended for production; some are implementing urea-formaldehyde molding powder seeing that raw materials, and then put them in the tableware after they are generally done. The outer surface is coated that has a layer of melamine powder. Tableware made of urea-formaldehyde is harmful to the skin. When consumers buy, they have to first go to standard stores and supermarkets. Don’t be greedy for cheap and purchase on the street stalls. Subsequently, when buying, check regardless of whether the appliance has apparent deformation, color difference, simple surface, and bottom. Whether it is uneven, whether the decal pattern is apparent, whether there are lines and wrinkles and bubbles, whether the colored tableware is rubbed between the two with a white paper napkin, whether there is any phenomenon for example fading.How to work with tableware properly Due for the special molecular structure regarding melamine plastics, melamine tableware seriously isn't suitable for use inside microwave ovens, and cracking will probably occur if used. For your cleaning of melamine plastic-type tableware, use a softer cloth. Do not use scouring pads and scouring powder to completely clean the surface of your tableware, because scouring pads in addition to scouring powder will wipe the surface of the tableware.,Making it more prone to contamination.https://www.eastchem.com.cn/Melamine-Products-pl3283253.html2021ld

  • yan zheng created a new blog post, laser driving lights
    laser driving lights
    The function of a laser car light is comparable to that of a shrewd taillight: it consists of a new laser diode located at the rear of the vehicle, and sends a vivid and clear signal into the car behind, telling the driver to never get too near to the car.The laser beam is emitted downward in a certain angle to make certain it does not specifically illuminate the human attention. When it is fired up under normal conditions, it truly is nothing unusual except to the two extra projection bars about the ground at the back, but it will come to be a triangular light danger signal inclined to the street in rain and fog, which is easier to become found than traditional errors lights.,The penetrating power can be stronger.As an auxiliary light, laser provides a lengthier distance for driving, maximizes light output, and expands the visible range of driving to twice the previous, thus providing the best driving lights.The new laser-driven lamp pays more attention to the irradiation distance of your whole area, not just featuring the laser part. There's a larger lens reflector cup across the laser prism to highlight the irradiation division of the laser chip.The laser driving light is lighter in weight, but has no relation to the load. This may reduce weight, facilitate arrest transportation, and save expenses.The laser car lights must pass the overseas FDA certification, and the emitted laser must abide by safety regulations, so so it will not cause any kind of harm to human eyes and possess a safety guarantee.The laser car light has a sturdy aluminum alloy shell to obtain efficient heat dissipation and so have a longer support life. In addition, its PC lens is definitely sturdy and durable and can withstand many bad weather.https://www.jg-ledlight.com/Laser-Driving-Light-pl3348633.html2021ld

  • The piezoelectric buzzer is made of piezoelectric buzzer element, which is made of piezoelectric ceramic technology. It is necessary to plate electrodes on both sides of the piezoelectric element, which is mainly used for energizing and supplying the piezoelectric buzzer. After applying the driving control signal that affects the AC, the piezoelectric buzzer will produce a mechanical engineering deformation of the expansion and contraction because of the piezoelectric effect, which can effectively push the metal sheet vibration system attached with the piezoelectric ceramic sheet. Piezoelectric buzzer’s sound needs to vibrate back and forth through a piezoelectric element, so we need to use square wave signal data to drive, which requires a higher driving system voltage to get a larger sound.

    Compared with piezoelectric buzzer, electromagnetic buzzer works under lower voltage and higher current, while piezoelectric buzzer’s maximum sound pressure level capability is usually higher than that of an electromagnetic buzzer. In an electromagnetic buzzer, current is driven through a coil to generate a magnetic field. When the current exists, the flexible ferromagnetic disk is attracted by the coil. When the current does not flow through the coil, the flexible ferromagnetic disk returns to the "rest" position. The sound produced by the magnetic buzzer is produced by the movement of the ferromagnetic disk in a similar way to the way the cone in the speaker produces sound.

    The difference between a piezoelectric buzzer and an electromagnetic buzzer is that piezoelectric buzzers are of lower current consumption and works at higher rated frequency and wider operating voltage. The piezoelectric buzzer is modeled as a capacitor, and the electromagnetic buzzer is modeled as a coil in series with a resistor.

    What is the difference between passive piezo buzzers and active piezo buzzers?
    The reason for distinguishing the two piezo buzzers is that they have different generation principles, and the parts used to be matched are also different.

    1. If you apply a DC voltage to them and make a buzzing sound, it means it is an active piezo buzzer.

    2. Using an ohmmeter, if you find resistance between the piezo buzzer’s pins, it is a passive buzzer.

    3. The active buzzer has a built-in oscillation source, so it’s simple to design in, but it oscillates at a specific frequency.

    4. Passive piezo buzzers need external driving circuit and is complex to design in, and it runs on AC only, they usually are called 'Transducers', 'Elements' instead of 'Buzzers'. While active piezo buzzers run on DC/AC, and are usually called indicators.

    What should be considered when buying a piezo buzzer?
    1. There are many specifications and varieties of piezo buzzers, such as piezoelectric buzzers and electromagnetic buzzers.

    2. Working voltage: Electromagnetic buzzer ranges from 1. 5 to 30V and piezoelectric buzzer ranges from 3 to 250V. Therefore, the piezoelectric buzzer is more commonly used, and a voltage above 9V can get a relatively higher SPL.

    3. Current consumption: Depending on the voltage, it ranges from tens to hundreds of milliamperes. The piezo buzzer is so relatively power-saving that lower milliamperes can work normally, while the magnetic buzzer needs about three times more current when it starts.

    4. Frequency ranges: Piezo buzzers tend to exhibit a more linear relationship between the input frequency and output audio power, while magnetic buzzers tend to have a less linear relationship. Therefore, piezo buzzers tend to have a wider range of usable frequencies than magnetic buzzers.

    The above are some aspects that we need to consider when choosing a buzzer. You can choose according to your actual situation and the specifications of the buzzer.



    Learning something about piezo buzzer can help you know the difference between the piezo buzzers and the magnetic buzzers, or even the more detail about the passive piezo buzzer and active piezo buzzers. If you want to buy high-quality piezo buzzers with reasonable price, Kailitech Company can provide you with the best products.

  • Some of you may already be familiar with the OBD technology, but for those who are not familiar, let me briefly introduce it for you. OBD stands for on-board diagnostics, which constitutes a standard system for computer networks in cars or trucks. And OBD scanner is an external diagnostic tool used with the OBD system on the vehicle. It is used to diagnose (or more accurately, self-diagnose) any problems related to the car and report it to the user.



    Here is the content list:

    How to choose the right OBD-ii Scanner?

    About Fiberall's OBD Scanner product introduction

    What should I pay attention to when buying OBD Scanner?



    How to choose the right OBD-ii Scanner?
    Now, you may be wondering how OBD-ii Scanner is different from its predecessor, OBD Scanner. In the latter, the design and work are OEM-specific, and its nested generation uses similar communication processes, connectors and code patterns.

    So far, you may have gained some knowledge about OBD-ii Scanner and its functions. Let us now look at all the different factors to consider when choosing OBD-ii Scanner. The task of choosing OBD-ii Scanner is not as easy as it seems.



    When you set out to buy on your own, you need to have an exact understanding of your car. Since each car is unique and needs to be processed in this way, choosing the right OBD-ii Scanner is a relatively tedious task. However, once the installation is complete, your car will be safer and the experience will be better than ever.

    What should I pay attention to when buying OBD Scanner?
    First, determine which car scanner you really intend to use, whether you need OBD-ii Scanner or just OBD1 Scanner. OBD1 Scanner has limited functions. It has several functions, basically all of which are designed to inform users about problems that need to be diagnosed. For those with limited budgets, OBD1 Scanner will be a good choice. OBD1 Scanner has a compatibility-related issue, that is, not all car models can use these basic code readers. Also don't get me wrong, the basic model is also an effective tool and can save lives.



    On the other hand, when starting to buy OBD Scanner for your car, there are some considerations to consider. Therefore, before buying, you need to ask yourself some basic questions. High-end models are more advanced. Choosing OBD-ii Scanner can provide drivers with great confidence and safety. OBD-ii Scanner has wider compatibility and has many features and functions, such as:

    Poor air control-the system can detect anti-lock braking systems, airbags and other functions of the car, and can also reset them.

    Information on the screen-The diagnostic code is displayed directly on the screen to provide a better user experience.

    Printability-the detected code and subsequent results can be made into physical copies, that is, the information can be passed to the printer when necessary.

    Real-time dynamic-real-time display of all information about the working status of the car and its sensors. This provides users with accurate and updated information, and any abnormal information will be reported at the same time.

    Storage and data logging-Data and information are stored securely in the sensor memory so they can be accessed at any time in the future. This data can be used to identify a specific car and evaluate its past.

  • Several electronic devices today apply piezoelectricity. For example, if you use some type of voice-recognition program, or even Siri on your smartphone, the microphone that you’re speaking into may perhaps be using piezoelectricity. That piezo crystal becomes the sound energy as part of your voice, and changes it into electrical signals to your computer or your phone to interpret.
    Piezoelectric materials are materials which could produce electricity due that will mechanical stress, such when compression. These materials can deform when voltage (electricity) will be applied.

    All piezoelectric materials are non-conductive in order that the piezoelectric effect to be able to occur and work. The actual piezoelectric actuator has a considerable amount of uses and applications. One example is, knitting machinery and braille models use these actuators, since they have such several moving parts and an exceptionally simple design. They could even be found in video digital cameras and cellular phones, all around health are proven most proficient being a auto-focusing mechanism.

    Active buzzers are configured as indicators require only a dc voltage to operate and are limited to a single audio frequency operation. Kailitech active piezo buzzers include dimension range from diameter or length and width from 9. 0mm ~ 100mm, height from 1. 8mm ~65mm, SPL range from 65dB~ 120dB. Housing material can be ABS, PBT, PPO, LCP, etc.,and mounting methods including lead wire type, terminal type, pin type and panel screw terminals.

  • which rubber product is important
    •   News
    •   Monday, 29 March 2021
    What the heck is Synthetic Rubber?Synthetic rubber production begins by utilizing petrochemicals in chemical crops, including neoprene (polychloroprene) plus emulsion styrene-butadiene rubber (E-SBR), the synthetic rubber that compensates most vehicle tires.This production of synthetic plastic begins with oil, coal, or maybe other hydrocarbons, which are refined to produce naphtha. Then, the naphtha is in addition to natural gas to manufacture monomers, such as butadiene, styrene, isoprene, chloroprene, ethylene, or maybe propylene.Then, the substance is polymerized using a catalyst and process heavy steam. As a result, chains of polymers form to generate rubber, which can become further vulcanized as required.Natural Rubber versus Manufactured Rubber Properties Synthetic rubbers are available in many forms, thanks on the wide range of applications through the industrial market. A few examples include styrene-butadiene rubberized, polybutadiene rubber, and polyisoprene plastic.Since synthetic rubber is required in vastly different approaches, its properties vary from form to create. But in general, there are still distinct differences between normal and synthetic rubber which might be important to note.Natural Rubber Properties Natural rubber is repellent to wear from chipping and tearing as a result of its high tensile energy. Damages from heat, mild, and ozone exposure, however, are more likely. It is tacky properties, especially to steel cords, make them common in vehicle tires.Synthetic Rubber Synthetic plastic is more resistant for you to abrasion than natural rubberized. Its grease and oil resistance also causes it to become a popular choice to get corrosive environments.Synthetic rubber has a strong resistance in order to heat and time—many models of synthetic rubber are also flame-resistant. This makes it a common choice for electric padding. Synthetic rubber is in addition flexible, even in comparatively low temperatures.Synthetic rubber is additionally used today because associated with its availability and ease of production, and in specific circumstances that require it is resistance to extreme temperature and corrosion.To test the properties of the natural or synthetic rubber in a variety of environments and situations, phone ACE Products and Advisory.There are countless different applications for different man-made rubbers, ranging from gum to sporting goods to help belts and moldings.Natural rubber is often used to produce high-performance vehicle tires that can need excellent tear durability, even at high temperatures caused by friction. Aircraft tires, weighty truck tires, and even sophisticated race car tires will often be made from natural rubberized.https://www.gofairubber.com/Rubber-products-pl3655743.html2021ld

    indoor playground
    Indoor children's playground can be a professional educational service organization dedicated to providing growth for youngsters aged 0-6. Unlike additional amusement organizations, children's playgrounds need to put children's safety very first.Indoor children's playgrounds usually are mostly set indoors, and through some imaginative amusement equipment and clever us going for sound, light, air, normal water, and color combinations to achieve the objective of entertainment and early instruction and exercise children.Children's playgrounds generally decide to open in several types of commercial areas 1. Plaza or perhaps shopping center: This kind of venue is of large grade and attracts groups with high spending power. Most young parents bring their children to play.2. Large-scale shopping department stores: This type of venue incorporates a large passenger flow, as well as a considerable part of the middle-aged and seniors (grandparents, etc. ) bring children to learn.3. Community, early education center: In communities around large residential areas, small commercial areas along with guaranteed passenger flow are an option.Indoor playgrounds have several benefits 1. Not restricted simply by geographical environment: Even if you have no good outdoor environment, as long as there is an area of several hundred square meters indoors, it truly is enough to open a new children's playground.2. Not plagued by the external weather: Whether it is windy or snowy or the sun's rays is scorching, the indoor children's playground can offer a comfortable environment for children that can be played.3. Getting started with operation management is not at all hard, and does not involve complex content such as inventory management.Opening a good indoor playground also calls for some prerequisites Safe as well as high-quality play equipment:Safety will be the first priority. Only high-quality enjoyment equipment can ensure this safety of children. Together, high-quality amusement equipment can also be the guarantee of the vitality from the park. Cheap play equipment besides increases the maintenance cost of the park, but it can be difficult to attract new members after the play products is damaged.https://www.playground.com.cn/Indoor-Soft-Playground-pl87320.html2021ld
