The difference between silicone products and rubber products in Dongguan silicone products factory
 
Silicone ProductsAnd the difference between rubber products
 
First: the definition of silica gel products is based on silica gel as the main raw material after a series of processing to obtain the general name of the finished product. Rubber products Dongguan silicone products factory is a rubber as the main raw material through a series of processing products.
 
Second: common features Their common features are special high elasticity, excellent wear resistance, shock absorption, insulation and sealing properties. There are many types and specifications of silicone products produced by the silicone industry. In 1983, there were more than 50000 kinds of silicone products produced in China. Silica gel is an elastic polymer. Silicone can be man-made, there are a considerable number of applications and products, such as tires, gaskets, etc. have become an important industry.
 
Third: according to the classification of silicone raw materials, silicone products can be divided into two categories of dry rubber products and rubber products. All silicone products made from dry rubber are collectively referred to as dry rubber products, such as tires, tapes, hoses, etc. The output of such products accounts for more than 90% of the output of silicone products. Products made directly from latex are collectively referred to as latex products, such as latex gloves, balloons, sponges, etc. The output of such products is less than 10% of the total output of rubber products. Silicone products can be divided into model products and non-model products.
 
Where silicone in the metal model in the shape and vulcanization of products, can be collectively referred to as model products, such as tires, silicone sealing products and silicone shock absorption products. However, in the rubber industry, it is customary to understand the model products as silicone models other than tires.
 
Products that are not shaped and vulcanized in the model are collectively referred to as non-model products, such as adhesive tape, rubber hose, adhesive tape, rubber roller, etc. Some silicone products (such as rubber shoes, etc.) can be produced by model and non-model methods. The performance of silicone raw material products depends on its structure and material. Many silicone products, such as tires, tape, hose, tape products, etc., using rubber and cord (see cord) or metal composite structure. The latter two usually act as a skeleton to ensure the strength and rigidity of the product.
 
The difference between silicone products and rubber products Fourth: Use Many silicone products can be used as final products directly in daily life, cultural and sports activities, medical and health and other aspects, such as rubber shoes, raincoats, word rubbers, rubber toys, hot water bags, gas masks, air mattresses, inflatable tents, etc. More silicone products are used for various mechanical equipment, instruments, transportation tools, buildings and other parts.
 
Take automobiles as an example. There are nearly 200 silicone products used in a car, including tires, seat cushions, door and window seals, wiper strips, fan belts, water tank hoses, brake hoses, dust covers, and various seals., Shock absorbing parts, etc. Another example is a silica gel diaphragm in the pressure reducing valve of the liquefied gas tank, a conductive silica gel button in the electronic calculator, a magnetic silica gel strip for sealing the refrigerator door, and about ten pieces of silica gel products in the color TV set.
Silicone as the main raw material processing system works, are called silicone products. Silica gel is a porous substance with different particle sizes formed by proper dehydration of silicic acid gel. It has an open porous structure and can absorb many substances. It is a good desiccant, adsorbent and catalyst carrier. Silica gel is a granular, glass, porous form of silicon dioxide prepared from synthetic sodium silicate. Silica gel is tough and hard; more solid than ordinary household gel-like gelatin and agar. It is a naturally occurring mineral refined and processed into any granular or beaded form.
 
As a desiccant, it has an average pore size of 2.4 nanometers and has a strong affinity for water molecules. Rubber products (rubber product) refers to natural and synthetic rubber as raw materials to produce a variety of rubber products activities, including the use of waste rubber reproduction of rubber products. The output of synthetic rubber has greatly exceeded that of natural rubber, of which the largest is styrene-butadiene rubber.
 
Rubber products, rubber products can be divided into synthetic rubber and natural rubber. The structure of natural rubber is high polymer of isoprene, which is made by processing and producing latex obtained from rubber plants. Synthetic silicone products are made by monomer polymerization or polycondensation. Synthetic rubber is deformed under external force and has the ability to quickly restore its original shape.
 
Because he has good physical properties, rubber products in the world include automobile tires, rubber hoses, sealing rings, adhesive tapes, insulating materials and other products. Generally, these products are synthetic rubber products. Compared with silicone products, rubber products are better than silicone products in toughness, poor wear resistance, dielectric properties and corrosion resistance. Therefore, rubber products are often used in large machines, industrial equipment and automobile transportation equipment.
 
Silicone ProductsFrom a chemical point of view, it is a one-component room temperature vulcanized liquid rubber product. It is an elastomer material made of silicone. Compared with rubber products, many products used in life now replace rubber products. Because silicone products are not toxic at first, while rubber products are toxic. At the same time, silicone products are colorless, tasteless, environmentally friendly and soft, but rubber products are smelly, colored, polluting the environment, in terms of price, rubber products than silicone products are very cheap. At this stage, the application range of silicone products is very light, and people's food, clothing, housing and medicine are involved.

What is the difference between silicone plug and rubber plug

Silicone plug and rubber plug which one effect is good? Then today we will popularize their difference to where the end point is. First of all, rubber plug products, as a common type of industrial products and accessories, or have strong advantages, such as dust and water resistance, wear resistance, tear resistance, aging resistance, oil seal resistance and ozone radiation resistance, etc., while rubber materials are divided into various types, and the side materials over there can be made of dozens of compound materials, so different attribute functions can be deployed for different needs, as for some industries such as mechanical tight closure, electronic tight closure, vehicle construction and even aerospace and military industry, rubber blocking is the most suitable. Silicone rubber plug and rubber plug have one thing in common. They can be molded in the molding vulcanizer of silicone product manufacturers. The difference is that they are more environmentally friendly, have good high and low temperature resistance, feel better when touching by color hands, and can be in contact with human body skin for a long time. Therefore, silicone plugs for earphones and medical grade silicone plugs are widely used even in food silicone appliances, mainly or because of the material in particular the nature of the achievements of its scope of application. Silicone plug is different. Its material is mainly based on environmental protection advantages, material texture and comfortable application. Therefore, it is used in some electronic products, survival products and small-scale waterproof and dustproof household appliances. Its raw materials are mixed by precipitation method silica gel, high-fine molecular silicone gum and white carbon black. The molecular chain of the product is called heart, soft and comfortable to use! Compared with the materials of silica gel and rubber, they can be compared as follows: new technologies are used in traditional industries. Rubber materials have been heard for a long time in early years, so the comparison of rubber materials accounts for the majority. Up to now, more and more silicone rubber products have been reused because they can replace larger usage compared with rubber, namely environmental protection performance and various technologies, such as shape, pattern and color, etc. www.mingzhen2006.com

What are the fields of application of silicone keys for equipment

Characteristics and uses of silica gel Silicone is a kind of rubber. The vulcanized silicone rubber has heat resistance, cold resistance, ozone resistance, atmospheric aging resistance and good electrical insulation properties. The disadvantage of silicone rubber is that the tensile strength and elongation at break are small, and the compression deformation is large. Suitable for making parts used in high temperature, low temperature, sunlight, atmosphere, ozone environment and electrical insulation parts. Dimensional accuracy and recommend marking tolerance Trajectory material is an elastomer, compared to the plastic material, the direct impact of the shrinkage rate of many and complex factors, precision than plastic parts more difficult to do accurate, in the specific design should be fully considered, there should be no high precision. If the basic size is too large to meet the dimensional accuracy required by the design, it can be solved by the method of deformation of the positioning column with the substrate. Where dimensional accuracy is required, there must be room for convenient mold repair in the design. Etched text and patterns Silicone substrate can be designed out of the trademark pattern and text, in the molding products at the same time molding out. The group and text on the products are convex and concave two types, considering the convenience of mold processing, are generally designed as convex. In order to facilitate the replacement of marks or models, the marked parts can be designed as inserts during mold design. When the product model changes, only the marked parts in the mold cavity can be replaced to meet the needs of mark replacement. As part of this type of article, it should be designed to allow the presence of flash debris at the contour of the insert tile at the marked location. For conductive rubber, the stroke is generally 0.8~1.5mm; the exhaust groove (I. e. gas pit) is designed to prevent adsorption between the PCB and the key action. For tact switches, the stroke depends on the stroke of the switch itself (and the stroke for preventing misoperation), as described later. If the substrate is not bonded to the PCB board, the structural element of the air slot can be omitted. The key design has a hand feeling problem. Different graphs correspond to different hand feelings. According to experience, when (FP-FC)/FP is 40%-60%, the hand feeling is better. Key Typical Structure and Application According to the specific occasions where the keys are used, as well as the specific requirements of the product for the service life, pressing force, and hand feeling of the keys, the structure and application of the keys are shown in the following figure. The life of the silicone key is directly related to the material and the inclined wall structure, and is determined according to the design requirements. Part of the product silicone key life reference: Remote controller: 500000 times; Telephone type: 1 million times; Laptop computers: 4 million to 5 million times; Computer keyboard: 500~10 million; The life of silicone keys for monitoring products is defined as more than 500000 times; The ordinary life of B super silicone keys is defined as more than 1 million times,

The convenience of the use of industrial silicone buttons

In order to solve the above problems and technical defects, after continuous updating and design, a multi-station silicone button trimming machine was invented, and a utility model patent was applied. The utility model relates to a multi-position silicone button trimming machine, which comprises a base, a gantry frame and four cutting cylinders, and the four cutting cylinders are arranged vertically on the top of the gantry frame in a horizontal straight line. The beneficial effect achieved by the utility model is that the structure design is reasonable. By adopting the combination design of four reinforcement tables and four cutting blades on the gantry, the device can simultaneously trim four silicone button products. Thereby greatly improving the efficiency of trimming processing of silicone products. With the continuous expansion of the silicone button market, how to improve the processing efficiency of the silicone button has made producers pay more and more attention. The trimming of the silicone button is an important step in the production process of the silicone button, and the trimming of the traditional silicone button The processing efficiency cannot be improved, which affects the overall production efficiency of the silicone button. Various types of silica gel have different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Silica gel according to its pore size is divided into: macroporous silica gel, coarse pore silica gel, type B silica gel, fine pore silica gel. www.mingzhen2006.com

What are the molding techniques of rubber products?

Calendering: suitable for the manufacture of simple sheet, plate products. It is a method of pressing the mixture into a film through a calender called calendering. Some rubber products (such as tires, tape, hose, etc.) used in textile fiber materials, coated with a thin layer of glue, glue coating process is generally completed on the calender. The fiber material needs to be dried and dipped before calendering. The purpose of drying is to reduce the moisture content of the fiber material (so as to avoid water evaporation and foaming) and increase the temperature of the fiber material to ensure the quality of the calendering process. Dipper is the process before hanging glue, the purpose is to improve the binding performance of fiber materials and glue. Extrusion molding: Used for more complex rubber products, such as tire treads, rubber tubes, and metal wire surface coatings, which need to be manufactured by extrusion molding. The plastic mixture was placed into the hopper of the extruder. Under the extrusion of the screw, a method of continuous molding through a variety of mouth before pressing out, the rubber material is preheated to make the rubber material soft and easy to extrude, so as to obtain rubber products with smooth surface and accurate size. The rubber industry is one of the important basic industries of the national economy. It not only provides people with light industrial rubber products that are indispensable in daily life, but also provides various rubber production equipment or rubber parts for heavy and emerging industries (such as mining, transportation, construction, machinery and electronic products). It can be seen that there are many kinds of products in the rubber industry, and the backward industry is very extensive. Molding molding: can also be used to manufacture some complex shapes (such as cups, seals) of rubber products, with the help of the molding of the female and male molds, the rubber material is placed in the mold and heated. www.mingzhen2006.com

How to print the pattern on the transparent key

Some laser marking machines have played opaque keys. While using laser typing to knock out the paint, they will also burn the plastic parts that can transmit light, but cannot transmit light! Changzhou laser marking machine has a special device, which can adjust the machine to the function of laser processing light-transmitting key. The laser can clean the paint sprayed on the surface very clean without burning light-transmitting plastic, thus realizing light-transmitting key laser processing!
