The present invention relates to a silicon mixing supply device, and more specifically, the silicon stock solutions A and B can be precisely mixed with a small amount of mixing and small amount injection according to the exact 1: 1 mixing ratio, thereby minimizing and minimizing the defect rate of silicone product molding. The present invention relates to a silicon mixing supply device capable of injection of silicon and having a product competitiveness that minimizes expensive silicon waste.

Generally, silicon is called silicon, and when we look at the characteristics of natural rubber and organic rubber, when it exceeds 100 ℃, it can not be used after aging for a short time.However, silicone rubber is generally used at 150 ℃ and intermittently for a short time. In the case of using, it is possible to even 300 degreeC (heat resistance).

In addition, since the saturation point of general organic rubber is -20 ℃ ~ -40 ℃, the silicone rubber is -60 ℃ ~ -70 ℃, so it maintains almost constant elasticity even at low temperature where general organic rubber is destroyed, so The best.

Unlike other organic rubbers, silicone rubber has very good weather resistance because there is no double bond that reacts with oxygen, ozone, ultraviolet rays, etc. in the molecular structure to cause cracking.

Silicone rubber has excellent oil resistance at high temperatures that ordinary organic rubber cannot use except fluorine rubber.

Silicone rubber is excellent in chemical resistance and hardly invaded by polar organic compounds such as acids and alkalis. However, strong acids or strong alkalis may be infringed, so if they are used in contact with them, they must be used after testing (chemical resistance).

The radiation resistance of silicone rubber is not particularly excellent compared to organic rubber, but it shows excellent characteristics when heat resistance is added and especially methyl phenyl silicone rubber is excellent.

Since silicone rubber does not contain a halogen element, it is characterized by low generation of toxic gases during combustion (flammability).

The thermal conductivity is higher than that of general organic rubber, so it can be used as insulation buffer for insulation coating and heat dissipation products (conductivity).

Silicone rubber has excellent oil resistance at high temperatures, which cannot be used by ordinary organic rubbers except fluorine rubber (compressed permanent reduction).

Silicone rubber is most suitable for the manufacture of foods and medical supplies because it is physiologically inert such as it is intrinsically harmless to humans and does not cause coagulation well (harmless).

Since silicone rubber has the lowest carbon ratio among molecules and does not use carbon black, which is used as filler in general organic synthetic rubber, it exhibits excellent resistance to arc or corona discharge under high voltage regardless of temperature and frequency. Used (electrical characteristics).

Therefore, as listed above, it is widely used in household goods, medical devices, industrial machines, and the like due to the characteristics of silicon.
