In order to control the vulcanization level of rubber O-rings, rubber sealing rings and other rubber products, and to improve the product quality, it is necessary to judge the suitable vulcanization premise of sealing products. Silica gel products have an open porous structure and can absorb many substances. It is a good desiccant, silica gel product adsorbent and catalyst carrier. The adsorption of silica gel is mainly physical adsorption, which can be regenerated and used repeatedly. Acid is added to the alkali metal silicate (such as sodium silicate) solution to acidify it, and then a certain amount of electrolyte is added to stir, that is, silicic acid gel is generated, or acid or ammonium salt can be added to the concentrated sodium silicate solution to generate silicic acid gel. On the premise of judging the vulcanization temperature, the vulcanization time varies with the thickness, shape and vulcanization rate of the product and the thermal conductivity of the filler. In addition, the heat transfer area of the sealing ring during vulcanization is closely related to the size and height of the model. In particular, the appearance of the porous mold (I .e. one mold with multiple eyes), as the mold cavities become compact, the heat transfer area of the model is correspondingly reduced, resulting in a drop of heat transfer consequences, the vulcanization temperature of rubber sealing products is individually controlled at about 150 ℃. With the development of China's rubber industry, vulcanization equipment for rubber sealing products has been gradually improved. Some factories have adopted vulcanization production methods such as folding vulcanization molds, fixing templates on flat vulcanizing machines and other equipment, mold shifting methods and transfer injection silicone products factory methods. The vulcanization premise of rubber sealing products is individually judged by the method of measuring rubber positive vulcanization, which can be judged by the methods of rubber tensile strength, effective elasticity, eternal deformation, hardness, constant load elongation, tear resistance, Mooney viscosity, etc. Silica gel products of silica gel key manufacturers have an open porous structure, can absorb many substances, and are a good desiccant, adsorbent and catalyst carrier. The adsorption effect of silica gel is mainly physical adsorption, can be regenerated and used repeatedly. Anti-static seals in the production process of rubber products:. 1, equipment grounding. 2, adhere to the air moist. 3. Wear anti-static clothes, wear anti-static shoes, eliminate chemical fiber clothes, and prohibit wearing insulated shoes. 4, the action can not be too hasty, too rough. 5. Avoid direct contact between rubber products and rollers. 6. Equipment and device inductive static eliminator. Silica gel products have an 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 absorption of rubber keys. It 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 to generate silicic acid gel, alternatively, the addition of an acid or ammonium salt to a more concentrated sodium silicate solution can also produce a silicic acid gel.

Classification of rubber sealing products such as rubber O-rings and rubber sealing rings: static sealing products between absolutely stationary joint surfaces and dynamic sealing products between absolutely movable joint surfaces. Silicone product manufacturers are easy to clean: silicone cake mold products can be recovered after rinsing with clean water or cleaned in a dishwasher. Long life: silicone material properties are very stable, made of cake mold products, silicone keys than other materials have a longer life. Soft and comfortable: thanks to the softness of the silicone material, the cake mold product feels comfortable to the touch, is extremely flexible and does not deform. Static sealing is mainly divided into: point sealing, glue sealing and contact sealing, which can also be divided into medium and low pressure static sealing and high pressure static sealing. Medium and low pressure static sealing usually uses gasket sealing with softer material and wider gasket. High pressure static sealing uses metal gasket with harder data and narrow contact width. Dynamic sealing may be divided into two basic types: rotary sealing and reciprocating sealing, according to whether the seal and its function are in contact with the moving parts of the absolute living liquid silica gel, it may be divided into contact seal and non-contact seal. The basic request for sealing is good sealing, strong insurance, long service life, and should strive for compact structure, simple system, convenient manufacturing and maintenance of silicone products factory, low cost, most of the seals are vulnerable parts, should guarantee the exchange, to achieve standardization, serialization. When purchasing seals for maintenance, the following procedures are advocated to improve the correctness of purchasing seals:. The direction of the movable silicone button manufacturer: first determine the movable direction of the position of the seal, such as reciprocating, rotating, spiral or fixed. 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. Grade of warm seal: refer to the original mechanical utilization instructions or evaluate the working temperature according to the actual working environment to determine the required utilization data. For the description of temperature grade, please refer to the following precautions for production users. Pressure grade: consult relevant data from the mechanical utilization instructions of the original rubber products factory, or infer the working pressure grade by looking at the hardness and structure of the original seal. for the description of pressure grade, please refer to the following precautions for production users. Rubber products material day rubber key rubber is mainly rubber hydrocarbon, containing a small amount of protein, water, resin acid, sugar and inorganic salt, etc., silica gel products have an open porous structure, can absorb many substances, is a good desiccant, adsorbent and catalyst carrier.

With the progress of science and technology, the development of society, people's daily life has been inseparable from plastic products and rubber products, if it is a professional engaged in these two industries, it is easy to mix them together. First of all, let's start with the difference between plastic silicone products and rubber. Simply put, if plastic is deformed under external force, it is difficult to restore to its original state, while rubber is easily restored to its original state. For example, if rubber O-ring is stretched by silicone keys, it will restore to its original state. However, if plastic tarpaulin is deformed, there will be no return to the original situation. In professional terms, that is, under the action of external force, plastic deformation is plastic deformation, while sealing ring rubber deformation is elastic deformation, which depends on their molecular structure. The elasticity of plastic is less than 100%, while rubber can exceed 1% thousand at most. Secondly, it is the difference in the production process of liquid silica gel. Rubber products have an additional vulcanization process. Silica gel sealing ring has an 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 absorption of silica gel products factory attachment, which can be regenerated and used repeatedly. Acid is added to alkali metal silicate (such as sodium silicate) solution to acidify it, then add a certain amount of electrolyte to stir, that is, to generate silicic acid gel. Silica gel can also be generated by silica gel key manufacturers or by adding acid or ammonium salt to concentrated sodium silicate solution. Silicone tube how to remove the smell, want to remove the taste of silicone tube generally there are two ways:. 1. If the silicone compound is made of anti-yellowing vulcanizing agent, the yellowing problem can be reduced. In addition, I suggest that your second-stage vulcanization should be baked at 160-170 degrees for 3-4 hours. If you want to reduce the smell, you can find a large water basin for the finished product (the water temperature is 70-80 degrees, the finished product should be soaked in rubber products for a period of time, washed, dried, and packed, and then OK, I have a customer to make drinking water matching silicone tube, hardness 50 degrees, using this method. 2. It is easy to vulcanize with platinum, and the cost of rubber keys is higher. At present, silicone tube to remove the taste of commonly used on these two methods, silicone tube in daily life outside the application to what aspects of the people can be based on their own actual situation to decide which method to use.

We buy in the life of the local rubber products with a very bad smell, pungent smell, there are no smell, O-ring seal is usually selected to try to choose a large cross-section of the O-ring. In the case of the same gap. O-ring is squeezed into the gap of the volume should be less than the maximum allowable value is squeezed into the silica gel products, silica gel sealing ring has an open porous structure, can absorb many substances, is a good desiccant, adsorbent and catalyst carrier, silica gel adsorption is mainly physical adsorption, can be regenerated and repeated use. Add acid to the alkali metal silicate (such as silicic acid silica gel key sodium) solution to acidify it, and then add a certain amount of electrolyte to stir, I .e. generate silicic acid gel, or add acid or ammonium salt to the concentrated sodium silicate solution to generate silicic acid gel. then, why is there such a scene, it has to be mentioned, sealing ring rubber deodorant. As the name implies, one kind of rubber deodorant is white powder or transparent liquid used to eliminate, weaken or shield peculiar smell. Silica gel sealing ring has an open porous structure and can absorb many substances. It is a good desiccant, adsorbent and catalyst-loaded liquid silica gel. 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 to acidify it, then add a certain amount of electrolyte to stir, I .e. generate silicic acid gel. Silicic acid gel can also be generated by silica gel product factory or adding acid or ammonium salt to concentrated sodium silicate solution. Its characteristics are: temperature resistance, long aging, non-toxic, non-stimulating, can directly produce effect on active groups, has no effect on the function of rubber products themselves, and makes active groups no longer volatilize to the surrounding environment, it can effectively reduce or eliminate the odor or peculiar smell caused by rubber additives and rubber residual monomers, and is especially suitable for some rubber products that are reprocessed by secondary recycling. Food-grade silicone tube is a silicone tube produced by using imported silicone raw materials, using scientific production technology and intermittent method. It is produced according to the characteristics of high tear resistance and high transparency of sealing gas phase adhesive, ultra-high and lower hardness of mixed adhesive, functional mixed adhesive, etc. This product has more extensive adaptability.

Silica gel as the main raw material of the processing works, are called silica gel products, silica gel is made of silicic acid gel properly dehydrated into different particle sizes of porous substances, with an open porous structure, can absorb many substances, is a very good silica gel products desiccant, adsorbent and catalyst carrier, then what are the factors affecting silica gel products. 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 the silica gel keys flow under the action of external force, the internal friction or flow internal resistance between molecules is usually proportional to viscosity and hardness. 2. Hardness. The ability of the material to partially resist hard objects pressed into its surface is called hardness. Silicone rubber has a hardness range of 10 to 80 sealing rings, which gives designers sufficient freedom to choose the required hardness. To achieve specific functions well, the mixing of polymer substrates, fillers and additives in different proportions can achieve various intermediate hardness liquid silica gel values. Similarly, the time and temperature of heat curing can also change the hardness without destroying other physical characteristics. 3. Tensile strength, silicone product factory tensile strength refers to the force required in each range unit to cause a rubber material sample to tear. The tensile strength range of heat-sulfurized solid silicone rubber is between 4.0-12.5MPa, the tensile strength range of fluorosilicone rubber is between 8.7-12.1MPa, and the tensile strength range of liquid silicone rubber is between 3.6-11.0MPa. What are the properties of silicone rubber products. 1, high temperature performance, silicone rubber products is characterized by high temperature stability, although the strength of silicone rubber at room temperature is only half of natural seal rubber or some synthetic rubber, but in the high temperature environment above 200 ℃, silicone rubber can still maintain a certain degree of flexibility, resilience and surface hardness, and no obvious change in mechanical properties. The glass transition temperature of silicone rubber products is generally -70 ~-50 ℃, and the special formula can reach -100 ℃, indicating that its low temperature performance is excellent, which is of great significance to the aviation and aerospace industries. 3, weather-resistant silicone rubber Si-O-Si rubber keys are very stable to oxygen, ozone and ultraviolet light, without any additives, it has excellent weather resistance. 4. Electrical properties, silicone rubber has excellent insulation properties, corona resistance and arc resistance are also very good.
