1、Rock cotton：inorganci fiber board made of basalt as the king raw material and processed by high temperature melting .
2、mine board：taking maineral cotton as the main raw material,starch as the main binder,adding appropriate amount of auxiliaries and additives,through batching,molding ,dehydration,gelatinization and dring,cutting,planing,finishing,spraying,packaging and son on,a ceiling decoration material which integrates the functions of heat preservation,heat insulation,sound absorption,fire prevention,decoration and so on.
1、Rock cotton holding point：
The raw material of external wall rock cotton board is natural volcanic rock,which is a non-combutible fire prevention material for building materials.
The outer rock cotton board has slender and flexible fiber and low slag ball content.Therefore,the therml conductivity is low and the heat preservation effect is good.
（3）sound absorption and noise reduction
2、Characteristcis of mineral cotton board：
1）the decoration effect is excellent.The mine cotton board has rich and colorful plane pattern,relief.
2）good heat insulation performance.The thermal conductivity of ore cotton board is very low.It's a good insulation material It can make indoor warm in winter and cool in summer,and save energy effectively for users.
3）Sound absorption and noise reduction,The main raw material of mineral cotton board is ultra-fine mineral cotton fiber,its density is between 200×450kg/㎡，so it has rich through holes,can effectively absorb sound waves,reduce acoustic reflection,so as to improve indoor sound quality and reduce noise.
4）Safety and fire prevention,Because the mineral cotton is an inorgnic material,can not burn,the organic content of the mine cotton board is very low,so the mineral cotton board can meet the requirements of non-flammable B1class and our products meet the requirements of non-combusible A class
2、Mine cotton board application:the mine cotton sound absorptionboard has the superior perfomance of sound absorption,non-combustion,heat insulation,decoration and so on,It is widely used in all kinds of building ceiling and wall interior decoration,such as hotels,resraurants,theatres,shopping malls,and public places,broadcasting rooms,studio,computer room and industrial buildings,etc.The product can control air humidity and adjust reverberation time,improve indoor sound quality,reduce noise ,improve living environment and working conditions,at the same time, the non-flammability of the product can meet the fire prevention requirements of architectural design.
