How is the elasticity of silicone products evaluated?

How is the elasticity of silicone products evaluated?

2020-09-18 10:42:12

Silicone products will have some undesirable phenomena if they are not paid attention to in the production and manufacturing process. For example, silicone products have poor elasticity, while some frequently used silicone products have certain requirements on tensile toughness, and the products mainly need his tensile toughness to maintain. Therefore, when silicone materials used in some machinery industries have insufficient tensile strength and rebound shock absorption failure, other properties of the product will be useless, then, what is the reason for the lack of elasticity of silicone products. First, raw materials: for raw materials, ordinary silica gel will have some problems, such as service life is not up to the standard of silica gel products, poor toughness, insufficient rebound, adding too much silicone oil and white carbon black to silica gel raw materials leads to disordered performance of silica gel products, silicon atoms in silicone resin are destroyed, softness is reduced, stickiness occurs, softness fluidity is not good, resulting in a decrease in tensile strength of products after high temperature molding, the product will not be reflected after the production is completed, but after a period of use in a variety of environmental conflicts will gradually appear product deformation, rebound rate decline, product stickiness and other phenomena. II. Machine: sometimes in the vulcanization process, in order to improve the output and increase the production efficiency, the products produced by reducing the vulcanization time in the silicone product factory will become soft. for increasing the output, the temperature must be increased to reach a certain balance rate under the premise of reducing the time, otherwise the products will have various undesirable phenomena, and the products produced for too long will be torn if they are too brittle and stretched, it is recommended to properly control the time and vulcanization temperature of the product during the production process. There are many kinds of rubber products, rubber O-rings, rubber seals, silicone O-rings, silicone seals, fluorine O-rings, fluorine seals, silicone rubber products, etc. But its production process, but basically the same. The important materials of rubber products include raw rubber, compounding agent, silica gel products have open porous structure and can absorb many substances. It is a good desiccant, adsorbent and catalyst carrier. The adsorption effect of silica gel is mainly physical adsorption, which can be regenerated and used repeatedly. Acid is added to alkali metal silicate (such as sodium silicate) solution to acidify it, and then a certain amount of electrolyte is added for stirring, that is, a silicic acid gel is formed, or an acid or ammonium salt is added to a concentrated sodium silicate solution to form a silicic acid gel. In order to make the raw rubber and the complexing agent uniformly confused with each other, it is necessary to process some data. This process is called mixing.. 14 years of silicone rubber professional custom manufacturing manufacturers, to provide you with the best products, silicone products factory in dongguan city custom phone: 0769-86652688-808,http://www.dgminz.com/

How to control the quality of rubber seals

How to control the quality of rubber seals

2020-09-16 11:48:00

The application range of silicone products is very wide, because it is non-toxic and environmentally friendly, and does not rely on oil resources, so all aspects of our lives have the emergence of silicone products, so what circumstances will affect the quality of silicone products. First, the quality of silicone raw materials: the quality of raw materials will lead to difficult to dismantle the edge of silicone products, poor quality of silicone raw materials, its toughness is insufficient, tear strength is obviously insufficient, in the process of dismantling the edge is certainly difficult to dismantle the edge. Second, in the molding process: the product is relatively thick, so the burrs are actually relatively thick silicone products, and the increase in thickness will definitely lead to the difficulty of edge removal. Third, the problem of molding die: if the self-disassembly design of the die is unreasonable, the use of the molding die is too long, and the quality of the molding die is not up to standard, these situations will make it difficult to dismantle the edge after production and molding. Fourth, vulcanization environmental factors: vulcanization temperature should be appropriate, too high or too low will lead to difficult to dismantle the edge, at the same time, vulcanization time also needs to be well controlled, vulcanization time is too long will lead to brittle products, vulcanization time is too short will lead to vulcanization link ineffective, silicone products factory so vulcanization link must be well controlled. The correct methods for choosing rubber seals are:. 1. Direction of movement-first determine the direction of movement of the position of the seal, such as reciprocating, rotating, spiral or fixed. 2. Sealing focus-for example, determine the active point is in the inner diameter of the pull rod seal or the active point is in the outer diameter of the piston seal, etc. 3. Temperature grade-refer to the original mechanical utilization instructions or evaluate the working temperature according to the actual working environment to determine the required utilization data. Silica gel products have an open porous structure and can absorb many rubber products. It is a good desiccant, adsorbent and catalyst carrier. The adsorption of silica gel is mainly physical adsorption, which can be regenerated and used repeatedly. Acid is added to alkali metal silicate (such as sodium silicate) solution, make it acidic, and then add a certain amount of electrolyte to stir, that is, the formation of silicic acid gel, or in a more concentrated sodium silicate solution with acid or ammonium salt can also generate silicic acid gel. 4. Pressure rating-check the relevant data from the original mechanical utilization instructions, or infer the working pressure rating by looking at the hardness and structure of the original seal. silicone rubber professional custom manufacturing manufacturers, to provide you with the best products, silicone products factory in dongguan city custom tel: 0769-86652688-808,https://www.mingzhen2006.com

Silicone products believe that many people already know that it is an environmentally friendly, non-toxic, healthy and safe material, but what are the factors that affect the production process. 1. Viscosity: explanation of scientific and technological terms: the volume characteristics of liquid, pseudo-liquid or pseudo-solid substances to resist flow, that is, when flowing under the action of external force, the internal friction or internal resistance between molecules is presented, usually the viscosity and hardness are proportional. 2. Hardness: The ability of materials to partially resist hard objects pressed into their surfaces is called hardness. Silicone rubber and silicone products have a Shore hardness range of 10 to 80, which gives designers sufficient freedom to choose the required hardness to best realize specific functions. Mixing polymer substrates, fillers and additives in different proportions can achieve various intermediate hardness values. Similarly, the time and temperature of heat curing can also change the hardness without destroying other physical characteristics. Silicone Products Factory 3. Tensile strength: Tensile strength refers to the force required on each range unit to cause a sample of rubber material to tear. Conductive silicone rubber is based on silicone rubber, adding conductive filler, crosslinking agent and other blending and vulcanization, commonly used rubber for methyl vinyl silicone rubber, commonly used conductive fillers are acetylene carbon black, carbon fiber, superconducting carbon black, graphite, copper powder, silver powder, aluminum powder and zinc powder. Compared with general conductive rubber, conductive silicone rubber has the advantages of small volume resistivity, low hardness, high and low temperature resistance (-70 to 200 ℃), aging resistance, and good processing and manufacturing process performance. It is especially suitable for manufacturing conductive rubber products with good performance, complex shape and small structure. It has the characteristics of high and low temperature resistance, aging resistance, and easy molding processing of common silicone rubber, and has good conductive stability and thermal stability. Because conductive silicone rubber has the advantages of small size, stable and reliable contact, good shockproof performance, and convenient replacement, it is used for the connection between printed circuits, radio integrated circuits, displays, etc., which can save a lot of welding labor and simplify assembly. Reduce the volume, reduce the cost, and improve the reliability. silicone rubber professional custom manufacturing manufacturers, to provide you with the best products, silicone products factory in dongguan city custom tel: 0769-86652688-808,https://www.mingzhen2006.com

The most important thing about silicone rubber products manufacturers customizing several rubber sealing rings is the problem of commodity molds. The customized production and processing of miniature silicone sealing rings have higher standards for self-trimming, because most of the miniature commodities with smaller specifications are all made of mechanical equipment to intelligently remove burrs from the trimming, and only manual simple cutting and repairing are required in human technology. Therefore, the quality precision of the mold and the selection standard of mold materials are relatively high, at the same time, the layout design and structure of the mold of the commodity is also very critical. The mold with clear sideline and clear feeding groove will certainly have corresponding assistance in the processing technology! As we all know, there is a difficult whole process from the development to the production and manufacture of several customized products. Silicone rubber products must be continuously tested from the specification and size installation of the developed products to the selection of raw materials for characteristic inspection. However, there are similar conditions in the whole process of silicone ring processing technology. An inconvenient process is likely to cause different problems in the processing of several products, what can't cross the past for silicone sealing rings? The key to the selection of raw materials, in many cases, the problem of commodity raw materials cannot be accurately predicted, because the silicone rubber sealing ring should be empty in the inner part of the hollow circle, while in the whole production process of silicone sealing ring manufacturers, the raw materials must be put into the positioning point for vulcanization, so the net weight of burrs is of course more than that of other commodities, so in many cases the cost budget does not match the net weight of the price deviation of commodities, the production cost deviation of the commodity. If the strength of the goods is not selected correctly, the actual sealing effect cannot be achieved. It is also extremely worrying for dealers and suppliers. Therefore, the routine application is determined by early sample determination! There are many difficult and miscellaneous diseases for silicone rubber O-rings, and the application fields of commodities are very wide. In addition to the above problems, the abnormal causes of commodities and their working efficiency should be fully considered in the processing process. At the same time, whether the commodities can achieve practical application results in terms of sealing performance and other components should be considered. The key significance of customized production and processing of silicone rubber is based on the requirements of customers, therefore, you have to look at the application of your products in that industry and natural environment!

The advantages of silicone keys for car use

The advantages of silicone keys for car use

2020-08-31 14:35:43

Why do cars use silicone rubber buttons, which are favored by users like the buttons now? Most online games feel that if they can't find a button that belongs to them, they feel that playing this hand tour has no soul. Even some brands marketing their own key mechanical equipment buttons have been used for more than 50 million times, so why not use such good mechanical equipment buttons on car buttons? The first cause of the 1. is that the switch button of mechanical equipment has a complicated structure and a high probability of problems. Our own experience has often caused the key of mechanical equipment that has not been bought for 30 days. It is not because the touch suddenly increases. It is very difficult to type two words until it is pressed very hard. 2. is the second reason: the cost increases, still due to the complicated structure of buttons and keys of mechanical equipment, it is obvious that every kind of spare parts in it is required to open a complete set of molds, with a complete set of plastic molds ranging from 5-60000 to 20-300000. Besides, the button pattern of the car is inconsistent, so there is no other way to choose a kind of vehicle commonly used, and the labor cost and project period will also appear longer. 3. then reason: car silicone rubber buttons are more integrated into a variety of environmental applications than mechanical device buttons, such as extreme weather and outdoor. Only from the perspective of suppressing the service life, although it is not as long as the button key of mechanical equipment. However, the resistance to violence is not as good as the silicone rubber button. If you hit me, I can still get back to the original state. If the mechanical equipment switch button is too hard, the inside structure will be disconnected.
