What is the classification of silicone seal ring? Its use?
Silicone is becoming more and more popular because of its environmental performance.
To understand the knowledge of silicone products, we must start from the original material of silicone. It can be classified according to the original material of silica gel, and can also be classified according to physical properties.

1. silicone raw material according to the performance can be divided into ordinary silica gel and meteorological silica gel:
 
1. Ordinary silica gel is also known as precipitated silica gel: * Color: translucent, white, gray, etc. * Hardness: 30, 40, 50, 60, 70, etc., commonly used between 40 and 70; * Density: 1.1-1.12g/c㎡; * Elongation: 400; * Usage: more use of mobile phone keys, miscellaneous parts, conductive adhesive and other low-grade silicone products.

2. Meteorological glue is also known as pure silica gel: * Color: transparent; * Hardness: 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, etc., commonly used between 40 ° and 60 °; * Features: Due to the good transparency and strong tensile strength of this material. High cost; * use: silicone tube, protective sleeve and other products need high elasticity.

The original material of 2. silica gel can be divided into solid silica gel and liquid silica gel according to its physical properties: solid silica gel is mainly used for molding products. For example:Silicone sleeve, silicone tableware, silicone keysLiquid silicone is mainly used for extrusion molding products, such as silicone nipple, silicone tube, etc. Insulated silicone pad, excellent high temperature resistance, silica gel (food grade silica gel) can withstand high temperature of 200 ℃ and can be used for a long time. The raw materials for the production of this product meet SGS standards and pass FDA food grade silica gel testing standards. It is tasteless and is produced by manufacturers according to models. The color and shape can be customized.
 
 
Silicone sealing ring material shape classification and use characteristics?
 
Silicone rubber is an adsorption material, is an amorphous substance, its chemical formula is mSiO2 & nH2O.
Silicone rubber sealing ring material is insoluble in water and any solvent, tasteless, stable chemical properties, in addition to strong alkali, hydrofluoric acid does not react with any substance.

Various types of sealing ring silica gel because of its different manufacturing methods and the formation of different microporous structure, the chemical composition and physical structure of silica gel determines that it has many similar sealing ring material is difficult to replace the characteristics, such as high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength and so on.

1. GeneralSilicone sealing ringAccording to its nature and composition, silica gel can be divided into two categories: silica gel and inorganic silica gel. According to its composition, it can be divided into extruded silica gel and molded silica gel;

Obviously, extrusion of silica gel is more common, such as household rice cookers on the sealing ring, called rice cooker silicone sealing ring; Molded silica gel is more complex, irregular shape, including silicone bowl, silicone ice, silicone cake mold and so on.

What is the main purpose of 2. silicone sealing ring material? 2.1 It can be used for sealing ring products on mechanical equipment, such as equipment, instruments, equipment and other closed conditions of moisture absorption and rust prevention;

2.2 silicone sealing ring because it is a food grade sealing material, so it can be used to design baby nipple and human contact products;
 
2.3 of materials commonly used in the manufacture of blood pumps;

The 2.4 is used in conjunction with ordinary silica gel desiccant to indicate the moisture absorption degree of the desiccant and judge the relative humidity of the environment. As a silica gel desiccant for packaging, it is widely used in instruments, leather, clothing, food, medicine and household appliances.

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
