good or solid silica gel liquid silica gel?
 
liquid silica gelThe main difference with solid silica gel is that one is liquid and the other is solid; but after processing the finished product, the two are not so easy to distinguish. The difference between liquid silica gel and solid silica gel is distinguished from the shape: liquid silica gel is in a liquid state and has fluidity; solid silica gel is solid and has no fluidity. Liquid silica gel and solid silica gel are distinguished from the field of use:
 
1, liquid silicone is generally used in baby supplies and kitchen supplies and medical supplies, can be in direct contact with food and the human body.
2, solid silica gel is generally used in daily necessities and industrial miscellaneous parts and auto parts.
3. Safety of liquid silica gel and solid silica gel: Liquid silica gel is a food-grade material with high transparency and high safety. It is molded without adding auxiliary materials such as vulcanizing agent, and is sealed and fed. Solid silica gel is a transparent material, molding need to add vulcanizing agent to speed up the vulcanization molding time, open mold feeding molding.
 
Liquid silica gel and solid silica gel are distinguished from the molding method:
 
1. Liquid silicone is injection molding liquid silicone (LSR): the full name is injection molding liquid silicone, and the vulcanization equipment is injection molding machine. The process flow of the injection molding machine is very simple, the product accuracy is high, the output is high (A/B glue is mixed at a certain temperature for a few seconds), it saves people, saves electricity, saves materials and many other advantages, and can produce all high-temperature glue. Products; It is a mainstream in the development of silicone materials in the coming years.
2, solid silicone molding is the raw material is a piece of solid, through the mixing machine mixing, cutting machine cut into products and mold appropriate size and thickness, and then put into the mold, pressure molding machine under a certain temperature molding. Demoulding is similar to that of plastic products, and it is also necessary to clean up the mold. Liquid silica gel and solid silica gel are distinguished from the finished products: liquid silica gel has high transparency, no peculiar smell, and the product has a glue injection port; Solid silica gel has a transparent bottom, with the fragrance of vulcanizing agent or other covering vulcanizing agent, and the product has no glue injection port.
 
What is the difference between liquid silicone and solid silicone molding process:

First introduced is the solid silica gel solid silica gel in the industry is water glass (sodium silicate) as raw material, in acidic medium hydrolysis gel, and then by aging, washing, drying process made of silica gel, according to the different water content, translucent or white solid. Commercially available are irregular granular, spherical and microspherical silica gels, which are commonly used as catalyst carriers in fluidized bed operations. 2. When used as a catalyst carrier, silica gel is usually impregnated in a solution containing catalytic active components, so that the solution is absorbed in the pores of silica gel, and the active components are distributed on the surface of silica gel through drying, activation and other procedures. The pore structure of silica gel has an important influence on the properties of the supported catalyst, such as the pore volume and pore size distribution of silica gel.
 
liquid silica gelIntroduction of the process
Liquid silica gel is usually used in industry to make sodium removal of water glass to make silica sol by ion exchange method. It is a translucent Milky White liquid with high stability. The silica sol becomes a porous solid upon drying. Silica gel is a kind of high and low temperature (-60~250 ℃), ozonation resistance and has good electrical insulation properties of special rubber. Organic silica gel is a special synthetic elastomer formed by mixing linear polysiloxane with reinforcing filler and vulcanizing under heating and pressurizing conditions. It has a perfect balance of mechanical and chemical properties, so it can meet the requirements of many demanding applications today.
 
Liquid silica gel has the characteristics of high and low temperature stability, inert (tasteless and odorless), transparent, easy to color, wide hardness range, chemical resistance, weather resistance, strong sealing performance and compression deformation resistance. The above description is about: liquid silica gel and solid silica gel process what are the different related content, liquid silica gel than solid silica gel is easier to process, due to the easy fluidity of liquid silica gel, which can be in the case of low energy consumption molding, calendering, extrusion, of course, this also reflects its high production efficiency advantages.
 
 
1. the appearance difference between liquid silica gel and solid can be seen from the appearance, one solid and one liquid.
1. Liquid silica gel is in a liquid state and has fluidity. It is a highly transparent and safe food-grade material. It does not add auxiliary materials such as vulcanizing agent when forming, and is sealed and fed.
2, solid silica gel is a solid state, no liquidity, he is also a transparent environmental protection material, molding need to add vulcanizing agent to speed up the vulcanization molding time, open mold feeding molding.
 
2. the difference between liquid silica gel and solid from the field of use

1,liquid silica gelGenerally used in baby supplies and kitchen supplies and medical supplies, is direct contact with food and the human body.
2, solid silica gel is generally used in daily necessities and industrial miscellaneous parts and auto parts.
3. Safety of liquid silica gel and solid silica gel: Liquid silica gel is a food-grade material with high transparency and high safety. It is molded without adding auxiliary materials such as vulcanizing agent, and is sealed and fed. Solid silica gel is a transparent material, molding need to add vulcanizing agent to speed up the vulcanization molding time, open mold feeding molding.
 
 
The advantages of solid silica gel: low investment, flexibility, low mold cost, a little less orders can also be connected, the rubber can be used in a wide range of choices, you can choose double 25 or Perkin. Disadvantages of solid silica gel: higher requirements for operators and low production efficiency.
The advantages of liquid silica gel: high production efficiency, relatively high hygiene level, and generally high product accuracy. Generally used in baby supplies and kitchen supplies and medical supplies, is direct contact with food and the human body.


The difference between liquid silica gel and solid silica gel can be divided into liquid silica gel and solid silica gel according to the type of existence. The physical properties of the two are different due to different forms, and the application is also quite different. This paper will discuss the difference between liquid silica gel and solid silica gel. Let's talk about solid silica gel. The vulcanized silica gel products and silica gel mixtures are all solid. The solid silica gel we are talking about here refers to silica gel mixtures.
 
This kind of silica gel is also called high temperature silica gel. No matter what kind of vulcanizing agent is used, it needs to be vulcanized at high temperature to obtain ideal physical properties. Solid silicone vulcanization, can be made into a variety of silicone products, generally have better physical properties. Solid silicone products are generally able to pass FDA tests after secondary vulcanization and meet food-grade standards. Therefore, solid silica gel can not only be made into industrial products, but also can be used in food contact. There are many varieties of liquid silica gel, but it is more than the original silicone material without vulcanization, which is liquid. Due to the sulfur dynamic, liquid silica gel is easier to shape, can be easily made into a mold, used to copy the product, this solid silica gel can not be made.
 
Liquid silica gel can also be made into adhesives for bonding various materials. Most liquid silicones can be vulcanized at room temperature. Liquid silica gel can be divided into condensation type liquid silica gel and addition type liquid silica gel according to the reaction type. Condensed silica gel is generally not up to food-grade standards, and addition type silica gel can generally meet food-grade standards, and has very good physical properties, and thus made of liquid silica gel products, used in all walks of life.

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
