保定Perlite finished bag filling

       The finished product is mainly used for low temperature device (large liquefied storage tank, air separation, etc.). Production factory fixed foam furnace, waterproof bag packaging, factory warehouse storage, trucks or rail transport to the site of the project.

       Can be used as a filtering agent, catalyst, molecular sieve, and rubber, the carrier of fertilizers and pesticides. Widely used in construction, metallurgy, petroleum, machinery, light industry, water and electricity, casting, medicine, food, agriculture, forestry and gardening departments and so on. Often temperature coefficient of thermal conductivity of 0.0245 ~ 0.048 W/(m K), high temperature heat conduction coefficient is 0.058 ~ 0.175 W/(m K), low heat conduction coefficient is 0.028 ~ 0.038 W/(m K), the highest temperature 800 ℃. Used as a efficient insulation, cold insulation filling material.

       The expanded perlite is perlite ore by preheating, an internal expansion made of instantaneous high temperature calcined honeycomb white granular materials. The principle is: Perlite ore crushing the formation of a certain size of ore, after preheating, rapid heating (more than 1000 DEG C), vaporization of water in tailings, expansion in the softening of the glass containing ore, the formation of porous structure of non-metallic mineral products volume expansion of 10-30 times. According to the technology and expanded perlite use divided into three forms: open hole (open cell) (closed, cell), obturator hollow hole (balloon).
