Silica gel is a kind of enzymatic adsorption material, which is an amorphous substance, and its chemical formula is mSiO2·nH2O. It does not dissolve water and all organic solvents, is non-toxic, odorless, and has stable physical properties. It does not react with all substances except strong acid and hydrochloric acid. Various types of silica gel have different microplate structures due to their different manufacturing methods.
The two-component organic chemistry and physical structure of silica gel determine that it has many characteristics that other similar materials cannot replace: high absorption performance, good heat resistance, stable physical properties, and high impact toughness.
Silicone seals actually refer to the general term for different types of silicone seal products, which are commonly used in everyone's daily life, industrial production, manufacturing, and medicine. Silicone seals are materials or parts that prevent liquid or solid particles from leaking from adjacent fusion surfaces and prevent external residues such as dust and water from intruding into the internal parts of the mechanical equipment.
Low temperature resistance can be as low as -60°C to -80°C, and high temperature resistance can be as high as +180°C to +350°C. Silicone is also resistant to various bending and bending deformations, and the damage is small due to backwardness. The third characteristic of silica gel depends on its ability to develop and use, blend, and compound with a variety of materials, so as to develop modified materials to obtain excellent comprehensive performance. The basic storage standards and regulations for silicone seals: The utensils are sealed and stored in a dark, shaded room. Therefore, you must pay attention to these aspects when storing silicone seals.
Food-grade silicone tube is made by adding raw silicone rubber to a double-roll rubber mixing machine or a closed kneader, slowly adding white carbon black and its modifiers to continuously refine the uniformity, according to the specifications of the field commodity standards, and make according to the extrusion As a commodity, it is widely used in biomedicine, laboratories, and medical equipment industries. Food-grade silicone tube is resistant to pressure, abrasion, and does not dissolve all tastes and smells. It belongs to the odorless silicone tube; the inner cavity is smooth and does not stick to water; the tube body is completely transparent and clear, and the fluidity of the material inside can be seen. It can be sterilized by high temperature. Autoclave.
Excellent anti-aging performance, tearing of the conditioning agent, excellent resilience, no deformation, resistance to weak acid and strong alkali, resistance to high and low temperature tests, etc., can be used at -50 degrees to 250 degrees, especially 300 degrees, high quality Dielectric strength, high air permeability, excellent physiological plasticity and physiological reliability.
The key uses of food-grade silicone tubing are: medical silicone tee joints, liquid delivery pipes, diagnosis and treatment hoses, small appliances (coffee machines, hot water pots, irons, rice cookers, frying machines, disinfection cupboards, vertical water dispensers, fruit Supporting facilities for mechanical equipment such as pulping machines, bread machines, gas appliances, electric water heaters, etc.). No matter what kind of grade it is, it will give full play to its great effects in industrial production and daily life.
