Silica gel is a highly active adsorption material is amorphous material, its chemical formula is mSiO2 · nH2O. Insoluble in water and any solvent, non-toxic, odorless, chemically stable, it does not react with any substance except alkali, hydrofluoric acid. Various types of silicone because different manufacturing method for the formation of different pore structure. Chemical composition and physical structure of silica gel, determines that it has many other features of similar materials difficult to replace obtained: adsorption properties, thermal stability, chemical stability, high mechanical strength.
Silicone materials have special properties, especially excellent biocompatibility and biologically inert, it has been more in the packaging materials in the field of biomedical engineering, medical devices, medical devices and biological sensors implanted in more applications.
In real life, there are always some accidents, so that we lose a few normal parts of the body. Then, with a normal body parts, for such people it is very important. Now, with the development, the emergence of silicone polymer materials science and technology, such problems can be solved. Thus, the new medical subjects - Silicone beauty came into being. Let's first understand the performance characteristics of the silicone material under, it is a synthetic silicone, non-toxic, environmentally friendly polymer materials, with weather resistance, high temperature resistance, corrosion resistance, pro-human and other fine features.
Identification of quality silicone wire
1, conductor (1) should be rounded and smooth surface, continuous coating and uniform (2) conductor surface should not have a triangular mouth, burrs, cracks, kinks, folds, inclusions, the scars, pits, mechanical wear, corrosion and other defects spots . (3) uniform color, bright, there should be no excessive oxidation traces. (4) adequate conductor cross-section dimensions, no loss side.
2, insulation and sheathing (1) the surface smooth and rounded, shiny uniform, should not have (2) insulation (sheath) uniform thickness eyesight visible knots, bubbles, burning, etc., not eccentric. (3)
No mechanical damage and flattening phenomenon (4) the adhesion between layers of material should not be.
3. Other (1) metal shield should be continuous, overlapping, closely around the package, no sharp corners, curling, lacuna and so on. (2) into the cable and uniform pitch matters. (3) filled with plump, rounded cables. (4) wrapping should overlap, should not have curling, omissions and other phenomena. (5) Cable shape should be rounded, not flattened, serpentine bending. (6) There should be no moisture inside the cable traces.
