In life we may experience the impregnating agent, today, small series to learn about life which impregnating agent.

As impregnant of many materials, such as water, wax, some vegetable oils, salt solutions (water glass), metal, resin. Can be widely used in modern industrial production mainly water glass, metal and resin.

Glass of water infiltration characteristics of water glass as an impregnation agent appeared early, used for casting crack sealing. Characterized by low price, contain a lot of water, relying on volatile water-cured, thus shrinking the larger, low rate. Additionally the treated parts cleaning do not clean, low production efficiency, immerse the field dirty. Now more and more resin instead.

Metal infiltration characteristics of metal impregnation agents mainly refer to low melting point metals, such as copper (copper alloy), Tin, etc. In powder metallurgy industry used more.

Resin infiltration characteristics of resin impregnation agents appear early in certain resins, are toxic. Nontoxic resin later appeared, casting, powder metallurgy is more and more widely used. It features low viscosity (thin), penetration ability, high quality, high production efficiency. Is its handling of parts easier to clean, immerse the venue clean.

Organic impregnating agents third generation 1992 year started synthetic ester based impregnating agent, belongs to the third generation, alternative to resin impregnation agent, which is easy to clean, does not plug the screw holes of the workpiece, hole, and heat resistance, solvent resistance, corrosion, thermal shock resistance, excellent performance, Currently in the advanced industrial countries have been widely used.

Above is our common impregnating agents, small hopes to write the above can you help!
