Silicone sealing ringThe advantage of_silicone sealing products leak-proof?
 
The advantages of silicone sealing ring all know that sealing products have many functions. In heavy industrial machinery and outside the electronics industry, their functions are often beyond your imagination! In life, sealing rings are commonly used in kitchenware items, mainly for insurance, heat preservation, drinking fountains, electric rice cookers, water cups, ovens, kettles and other protective sealing effects, so most daily necessities are inseparable from the tight elastic sealing function, once lost, it will affect the practical function of the whole product!
 
Silicone sealing ring can make your products have a good preservation effect, in the use of the process can make the food to get a good protection, to prevent leakage of gas, and silicone called environmental protection material, because it can meet the standards and requirements of food grade material, fully in line with the green environmental protection equipment!
 
Silicone products have certain environmental adaptability, can be applied in high and low temperature environment, and maintain good appearance and non-deformation state. They will not decompose harmful chemical substances in high and low temperature environment, so they can be applied around high-pressure electric rice cookers and refrigerators. As long as there is no size deviation on the product framework, there will be no leakage.
 
At present, many industrial rubber sealing products are gradually replaced by silica gel materials. The main reason is that they have better elasticity and can be used normally in different temperature environments in time. In terms of toughness and pull-up rebound strength, they can be divided into a variety of different materials, including ordinary pulling force and pure high pulling force raw materials. However, the selection of daily materials must reach the environmental protection level, so pure high pulling force raw materials are inevitable, natural toughness in the rebound strength can also achieve no fracture, no deformation, rebound effect is good.
 
The production principle of silica gel sealing products is mainly through the mixing of silica gel product manufacturers to intervene in the vulcanization of vulcanization additives at a high temperature of about 200 degrees. It has excellent temperature resistance, toughness and environmental adaptability. Therefore, after understanding the sealing products, do you think the function of silica gel sealing grease is very powerful?
Silicone sealing products are leak-proof in the industrial machinery industry. Oil leakage in pipelines often affects many of our machinery industries to stop production. For example, hydraulic presses are one of the manufacturers of silicone products. In addition, many mechanical seals in the machinery industry are not tight enough to cause oil leakage. Different industries have different processes and materials to solve the problem of oil leakage. On the other hand, oil leakage in pipelines is removed, there are certain solutions to the leakage of gas valves and valves, and today we mainly know how to deal with the leakage of mechanical pipelines. The most common phenomenon of oil leakage in industrial manufacturing, and the main reasons for pipeline leakage are as follows:
 
1. The pressure in the pipeline is too large to form extrusion phenomenon
 
2. The oil seal is damaged due to excessive movement of the motor shaft of the machine,
 
3. Different environments and the extension of time cause the oil seal to change greatly and lose its effectiveness. And several of these reasons can determine whether there is a certain relationship with the material of silicone products, so what are the main reasons?
 
1. Under the condition of long-term use of the product, the oil seal gap is too large due to pressure, and the bearing force is large, which leads to oil leakage.
 
2, in the long-term use of the process of strenuous exercise, back and forth to kill time too long, so that the toughness of the frequency increase, product fatigue cracks.
 
3. It belongs to the harsh environment for a long time, the temperature is too high, the ozone is too heavy, the liquid is soaked for a long time and other factors lead to the performance degradation.
 
4. The face of the mold is not flat enough, the product has unevenness, the dimensional accuracy cannot meet the requirements, and there are errors.
 
5. The material does not pass, the performance tests do not pass, the temperature resistance, oil seal resistance, toughness, etc. do not meet the requirements, etc. Silicone rubber sealing ring has certain sealing performance and has different raw inertness for different environments. As a piston original, it can solve most leakage phenomena. Of course, it is still not allowed to intervene in some specific environments. Appropriate silicone rubber sealing products are selected in the appropriate environment to achieve reasonable application effect. Therefore, the leakage problem of sealed pipelines can be solved from different angles.

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
