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.

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.

What causes the silicone tube to have dirt to identify counterfeit use

What causes the silicone tube to have dirt to identify counterfeit use

2020-11-19 14:13:33

In the production process of silicone rubber tube, sometimes there is such a situation, that is, the surface of silicone rubber tube is dirty with dirt, which is a typical bad appearance. For such problems, many silicone rubber products factory often have a headache, because if the products with dirt on the surface are submitted to customers, it will have a certain impact on the company's image, so what causes the silicone rubber tube to appear with dirt. 1, silicone key production surrounding environmental problems, production workshop, production mold, production equipment is not clean, resulting in silicone tube in the production process caused by a lot of dirt in the mold cavity, the production of silicone products with dirt.. 2, the external release sealing ring agent factor, the external release agent with dirt, resulting in spray release agent when the dirt will also be sprayed and adsorbed on the surface of the mold cavity, resulting in the formation of silicone tube surface dirt. 3, the electric heating plate factor, curing machine under the liquid silica gel electric heating plate with dirt, resulting in the mold when the dirt will be sucked into the mold cavity, resulting in silicone tube stains.. 4. The factor of silica gel raw material, the silica gel raw material itself is not well protected, with very dirty dirt silica gel products factory. How to identify the fake use skills of silicone rubber tube, because edible silicone is refined and sterilized, it can be mixed with food and drugs according to the required amount to directly ensure the drying of food and eat together with food, and has no toxic side effects on human body silicone key manufacturers. Therefore, parents who pay attention to the hygiene of infant entrance are all inclined to infant products made of silicone material. At present, many infant products use latex and rubber as silicone, even people in the seal industry must carefully distinguish between true and false, and generally choose through the following three tricks:. 1. Try elasticity: rubber and latex have better elasticity, and silica gel is relatively fragile. When selecting, you can try elasticity first. If rubber products have good elasticity, they may be rubber. 2, look at the color: rubber, latex due to the impurity content, can not do transparent color products, and silica gel is colorless and transparent, to do transparent silicone rubber products must be rubber keys with silicone raw materials. 3, smell: rubber, latex products taste strong, smell a smell will smell the pungent smell, some manufacturers in order to cover up the smell and increase the fragrance, so the choice of silicone material material will be much better.

Cause silicone tube tolerance size yellowing reasons

Cause silicone tube tolerance size yellowing reasons

What is the reason for the size of the silicone tube tolerance? There are tolerances in the production of any product. This tolerance is related to many factors. 1. Due to the influence of the head temperature, under the same extrusion conditions, if the head temperature is too low, the inner diameter of the extruded silicone sleeve becomes larger, and the wall thickness of the silicone hose becomes thinner. When the extrusion temperature is higher, the inner diameter of the silicone hose becomes smaller, and the wall thickness of the silicone hose becomes thicker. 2. Due to the influence of the melting point and fluidity of the extruded material, the fluidity of the silicone key material is closely related to the temperature. With the increase of temperature, the apparent viscosity of the material decreases and the fluidity is good. When the temperature of the machine head decreases, the apparent viscosity of the material is higher and the fluidity is poor. Forced extrusion makes the pressure of the machine head plus the sealing ring large, and the tube blank from the die produces elastic recovery due to the release of stress, the degree of expansion is also proportional to the previous pressure. At the same time, the poor fluidity of the material makes the material less extruded, resulting in the inner diameter of the silicone hose becoming larger and the wall thickness becoming thinner. With the gradual increase of temperature, the flow performance of the extruded material in the machine head is improved, the pressure of the machine head is reduced, and the extrusion inner diameter is reduced due to the corresponding reduction of stress elastic recovery. On the other hand, the extrusion amount of the material increases with the improvement of the flow performance of the silicone product factory, which thickens the wall of the silicone hose. 3, the influence of different screw speed and traction speed, at the same temperature, the diameter and wall thickness of the extruded silicone sleeve has a great relationship with the screw speed and traction speed. With the increase of the extrusion speed, the inner diameter of the silicone sleeve will become larger and the pipe wall will become thinner. The lower the head temperature, the more obvious the change will be. What is the cause of yellowing of transparent silicone products? Transparent silicone products have yellowing in a few years or months after production of seals. Sometimes during production, some newly released transparent silicone products look yellow and seem to have changed color. The properties of vulcanizing agent are divided into common type and yellowing resistance. Its application scope includes rubber products in the following two aspects:. 1. The ordinary type does not resist yellow vulcanizing agent, which can be used for some non-exposed silicone products with relatively deep color or low color requirements. 2. Anti-yellowing vulcanizing agent is applied to products that need to be exposed, have lighter and brighter colors, and require higher rubber buttons for colors. Sometimes we add anti-yellowing vulcanizing agent to the rubber compound, but the transparent silica gel product still looks yellow after molding, which may be that the anti-yellowing ability of the raw material is too poor, and the suggestion for the raw material with poor yellowing resistance is to change the material directly.
