What are the quality factors affecting silica gel products

2020-11-03 11:11:08

Silica gel is a granular, glass, porous form of silicon dioxide from the synthesis of sodium silicate, silica gel than ordinary household gel-like gelatin and agar hardness is higher, silica gel as the main raw material processing works, are called silica gel products, then silica gel products what quality factors affect. 1, the quality of silicone raw materials will lead to silicone products difficult to dismantle, poor quality of silicone raw materials its toughness is insufficient, tear strength is obviously insufficient, in the process of dismantling is certainly difficult to dismantle, silicone keys. 2. In the molding process, the product is relatively thick, so the burr is actually relatively thick, and the increase in thickness will definitely lead to the difficulty of edge removal. 3, vulcanization environmental factors, vulcanization temperature should be appropriate, too high or too low will lead to the sealing ring difficult to dismantle the edge, at the same time, vulcanization time also need to be well controlled, vulcanization time is too long will lead to brittle products, vulcanization time is too short will lead to vulcanization link no effect, so the vulcanization link must be well controlled. 4, liquid silicone molding mold problems, if the mold self-disassembly design is unreasonable, the molding mold is used for too long, the molding mold is seriously worn, the quality of the molding mold is not up to standard, etc. these situations will lead to difficult to dismantle after production molding. Silicone tube is the circulation and coating carrier of liquid and gas silicone products factories and other materials. Silicone rubber tubes in the industry can be divided into "extruded tubes" and "special-shaped tube strips". They are widely used in modern industry, national defense industry and daily necessities. If silicone tubes are used daily, silicone key manufacturers do not pay attention to them during use, which will lead to failure or aging of silicone tubes. Therefore, let's find out what causes lead to silicone tubes, the causes of aging are:. 1. Ozone has high chemical active oxygen and is more destructive. It also breaks the molecular chain of the seal. However, the effect of ozone on rubber varies with whether the rubber is deformed or not. When the rubber used for deformation is mainly unsaturated rubber), cracks in the direction of stress, I .e. so-called "ozone cracking", occur. When rubber products act on deformed rubber, only oxide films are generated on the surface without cracking. 2, the role of water has two aspects: rubber in the humid air rain or soaked in water, easy to damage, this is due to the water-soluble substances in the rubber and water rubber key group and other components are water extraction dissolved, hydrolysis or absorption and other reasons, especially in the water immersion and atmospheric exposure under the alternating action, will accelerate the destruction of rubber, however, in some cases, water does not damage the rubber, and even has the effect of delaying aging.

What are the benefits of transparent silicone keys

2020-10-30 16:37:54

Transparent silicone keys, like other silicone keys, can be used for many kinds of keys, such as transparent silicone lining keys, transparent silicone keys for instruments and equipment, etc. It is mainly used in electronic calculators, remote control systems, telephones, wireless telephones, computer keyboards, learning machine keys, cipher keys and digital product keys. Other industrial equipment are rarely used because transparent silicone keys are always clean, some transparent effect is better with crystal clear to describe it is not exaggerated, so it is more suitable for high-tech electronic products. As the name implies, transparent silicone keys are silicone keys with transparent effect. They are made of transparent silicone raw materials. Transparent silicone is a colorless or skin-colored oily liquid and becomes a soft elastic material after vulcanization. They can be used for a long time and maintain their soft and elastic properties in the temperature range of -65°C to 200°C. They have electrical properties and chemical stability, water resistance, ozone resistance, weather aging resistance, no corrosion resistance and physiological inertia, non-toxic and tasteless, low line shrinkage. Transparent silica gel can be divided into addition type transparent silica gel and condensation type silica gel. The advantages of using transparent silicone keys: first, it has a transparent effect and can be used for keys that need to transmit light; The second transparent silicone key does not need to add any pigment, which can reduce the artificial color matching process.

What is the problem of poor elasticity of silicone products

2020-10-30 15:25:49

In the molding process of the silicone product factory, the debugging and coordination of the machine has a certain influence. Sometimes in the vulcanization process, in order to improve the output and increase the production efficiency, the product that reduces the vulcanization time will soften. In order to increase the output, the temperature must be increased to reach a certain balance rate under the premise of reducing the time, otherwise the product will have various undesirable phenomena, however, if the product is too brittle and stretched for too long, it will also tear. It is suggested that the time and vulcanization temperature of the product should be properly controlled during the production process. Silicone products in the molding process a little do not pay attention to there will be some undesirable phenomena. Such as silicone products poor elasticity. And some of the more frequently used silica gel pieces have certain requirements for tensile toughness, and the product mainly needs his tensile toughness to maintain. Therefore, in some manufacturing industries, the use of silicone materials in the machinery industry once the strength is insufficient, rebound shock absorption failure, the other performance of the product will be useless. For raw materials, ordinary silica gel will have some problems, such as service life is not up to standard, poor toughness, and insufficient rebound. Adding too much silicone oil and white carbon black to the silica gel raw material leads to disordered performance of the product. The silicon atoms in the silicone resin are destroyed, the softness decreases, stickiness occurs, and the softness fluidity is not good, resulting in a decrease in the tensile strength of the product after high-temperature molding. The product will not be reflected after the production is completed. However, after a period of use, the product will gradually deform and the rebound rate will decrease, product stickiness and other phenomena.

How to distinguish the difference between medical silicone key manufacturers and ordinary ones

2020-10-24 15:16:03

In medical clinics, we can often see all kinds of silicone key manufacturers spare parts, such as medical silicone tube, blood oxygen detector finger clamp pad, breathing silicone mask, needle silicone plug, silicone rope tied to the hand and so on. At present, in the medical device industry, the most used in addition to drugs is medical devices, so why are medical silicone parts so much attention. The reason why silicone liquid silicone can receive extensive attention in the medical field is mainly due to the nature of the product itself and its structural characteristics. For example, the silicone key manufacturers used for sealing and packaging of medical drugs have certain elasticity, and can still maintain the original tightness and air tightness after needling, and no debris can fall off. The original characteristics of silicone itself are difficult to meet the current medical needs, however, it is possible to modify the silica gel or add some reagents to change its own shortcomings to meet the application in medical devices. At present, the two most widely used materials in medical devices are silicone rubber and polyurethane. Polyurethane has the advantages of good biocompatibility, excellent mechanical properties, easy molding and processing, and controllable performance. Silicone rubber has the advantages of physiological inert silicone button factory and good biocompatibility. These two materials have been discovered in medicine for a long time and have been paid attention to and studied by people in the industry. Silicone rubber is based on high molecular weight linear polyorganosiloxane, adding some specific components, in accordance with certain process requirements after processing, made with a certain strength and elongation of the rubber state elastomer. How to distinguish whether the silicone key manufacturers are food grade silicone. Food grade silica gel products are inorganic polymer colloidal materials made of silicic acid condensation-food grade silica gel. In line with non-toxic and tasteless, liquid silica gel has high transparency, stable chemical properties, soft and good elasticity, high and low temperature resistance, strong water absorption, no side effects on human body and other properties, while ordinary silica gel products use ordinary silica gel raw materials, and the products have great smell, and it will turn yellow or dark particles over time, such as the popular silicone steamer pad. Food grade silicone products smell without any uncomfortable smell, feel very soft, the ashes after burning is white, ordinary silicone products are white, burning will produce a lot of unpleasant smell, and the ashes after burning is black.

Why does the silicone handle cover process have good texture and feel

2020-10-23 10:59:48

Soft rubber protective equipment is now an indispensable peripheral protective equipment in many industries. Since the 1980 s, silicone rubber products have been widely used in military and construction, which has also opened a new door for soft silicone key manufacturers in the world. Now, with different types of silicone being developed and used, silicone sleeve has become a kind of just-needed product in life and many electronic equipment fields. The production process of silicone tube sleeve is mainly formed by high-temperature extrusion of hydraulic press. The shape and structure of the product are completely formed according to the mold structure. Silicone key manufacturers and silicone protective sleeve manufacturers can also be divided into different processes. The extrusion process can also make through-hole sleeve. In addition, it can be made by dipping process. Different production processes have different advantages. Pressing silicone key manufacturers are currently the most widely used processing method among all silicone processing technologies. This type of processing technology is mainly used to make silicone miscellaneous parts, accessories, electronic peripheral protective sheaths and some protective sheath shells with relatively complex structures. There is no problem at all in the production of silicone sleeves for unilateral sealing. The products are mainly formed by die clamping and extrusion, the production efficiency of the product is mainly determined by the size of the silicone key factory of the mold. For molded silicone key manufacturers, the biggest problem is that the size of the product is limited to the size of the mold. It is still a little difficult to make a large-size silicone sheath. In addition, the cost of this type of process is low, the mass production is large, and the processed product will have parting lines. If the appearance requirements are not too strict, it is recommended to choose this one. In the process of producing silicone key manufacturers, most of the silicone products are made of oil injection technology. Based on the requirements of customers, different inks are sprayed in the spraying process to produce liquid silicone key manufacturers with different feel. Spraying color oil: Spraying color oil is actually spraying various visible colors to the surface of silica gel key manufacturers. The process of spraying color oil ink is basically a process that every silica gel key needs to go through. After the spraying color oil process, pu or matting process can also be sprayed. Spray matting fog surface: matting ink is a hand feel ink that sprays a layer of fog surface on the surface of the product without affecting the color of the product. Its characteristics are actually similar to pu ink, but spraying matting ink will make the surface of the silicone key appear foggy, and it can spray frosted effect, and the hand feel is smoother by comparison.
