What are the main purpose of the silicone pad?

What are the main purpose of the silicone pad? Silicone pad was mostly silica, stable chemical properties, don't burn. Silicone pad is a kind of amorphous silica, should control the workshop dust content is not more than 10 mg/m3, need to be reinforced platoon wind, when wearing a mask.

Silicone pad has very strong adsorption capacity, drying effect on a person's skin, therefore, operation should be dressed in the uniform. If the silica gel into the eyes, need a lot of water flushing, and find a doctor as soon as possible.

Blue silica gel due to contain a small amount of cobalt chloride, toxic, and food contact should be avoided and the suction mouth, such as poisoning incidents should be looking for a doctor immediately.

Silicone pad in use process because of the medium water vapor adsorption or other organic substances, adsorption ability, can be regenerated through repeated use.

The silicone pad can be used as a desiccant, and can be repeated use.

Silicone pad is composed of silicate gel mSiO2 · nH2O appropriate dehydration of particles of different size of porous material. With open porous structure, specific surface is very big, can absorb a lot of material, is a kind of very good desiccant, adsorbent and catalyst carrier. Silica gel adsorption is mainly physical adsorption, can be recycled and repeatedly used. Adding acid to alkali metal silicate solution, acidification, stir and add a certain amount of electrolyte, namely generate silicate gel; Or in the concentration of sodium silicate solution adding acid or ammonium salt can also generate silicate gel. Silicic acid congealed gel will rest for a few hours of aging, then wash with hot water soluble salts, under 60 ~ 70 ℃ drying and activation when about 300 ℃, can get the silicone.

Silica gel with cobalt chloride solution after soaking and drying and activation, available color silica gel. Use it as a desiccant, before the water is blue, the water absorption after getting red, can be seen from the change of the color degree of water absorption, and whether to need to deal with the regeneration. Silicone is widely used in steam recycling, oil refining and the preparation of catalyst, etc.

Silica gel pad has excellent heat resistance, cold resistance, dielectric properties, resistance to ozone and atmospheric aging performance, such as silicone rubber outstanding performance is the use of wide temperature, can be in 60 ℃ temperature (or lower) to + 250 ℃ temperature (or higher) use for a long time. But the tensile strength and tear strength of silicone rubber poor mechanical properties, such as the physical and mechanical properties at room temperature is less than most of the synthetic rubber, and in addition to the nitrile silicon, fluorine and silicone rubber, poor general silicone oil resistance, solvent resistance, so the silicone should not be used in normal conditions, but very applicable to many specific occasions.

It is worth mentioning that in biomedical engineering, high polymer material plays an important role, and silicone rubber is particularly important in medical polymer materials, it has excellent physiological inertia, non-toxic, tasteless, non-corrosive, anticoagulant, good compatibility with the body, can withstand harsh conditions of disinfection. According to the need can be processed into pipe, sheet, film, and special-shaped components, can be used as medical apparatus and instruments, artificial organs, etc. Today has special medical grade silicon rubber at home and abroad.

The characteristics of the silicone pad: 70 a hardness; Durable, strong under pressure; Still have elasticity; Usually working temperature range: from - 100 ° F (73.3 ° C to 400 ° F (204.4 ° C); By CIP and SIP or ray sterilization or high pressure sterilization; Tolerance limit temperature, compression, chemicals, ozone, radiation, humidity and environmental exposure; For solution medium decomposition no smell and taste; Inventory is 12 feet in length; In tightly controlled environment and produced under strict good manufacturing procedures; To keep clean in production, sealed in a transparent polyethylene bags; On the bags and boxes are traceable products for the record; Quality control program after the record; According to the requirement to establish effective packaging; 0 or 45 degree Angle and roll the hose can use according to the requirements.
