Vermiculite Agriculture Raw Gold Prices Coarse Grade Vermiculite
1,What is vermiculite?
Vermiculite is a layer-structured metamorphic rock of gibbsite silicate. Rich in magnesium, it comes from hot-liquid-eroded or weathered phlogopite. When it is heated to lose water and expands, lt turns curvingas a leech. Therefore is called vermiculite.lt can be divide into original vermiculite and expanded vermiculite. color it can also be divided into golden vermiculite and white vermiculite.
2,Norms of raw vermiculite (Implementation standards JC/T810-1996)

3,Mainly Usage And Function
A,Building Materials,ligntweight building materials
On the roof with cement or asphalt or mineral fibers according to the proportion stirred for roof insulation,moisture-proof,but the house cool,also greatly reduce the pressure on the doors of the roof.
B,Widely used in the heat preservation of the wall
C,In particular high rise buildings in steel,construction steel coated with a layer to this fire-resistant coating on steel,when a fire occurs,extend,reduce damage to the steel structure of the building to the room personnel transfer valubalbe time.
D,Refractory products
Common mixing vermiculite can be pressed into brick kiln can also be used to steel mills,boilers,vermiculite fire board for walls,security doors,fire on the ship,fire retardent paint,paint the tunnel fire
E,Agriculture
a,Improve soil,often with peat,perlite as organic fertilizer,retain moisture,keep the soil permeability,improve fertilizer for release action.
b,Hatching ,breeding ,cutting,often the role of the field of pesticides,insecticides carrier,and the golf course turf
F,Feeding
Because vermiculite soft,non-toxic,sterile,good liquidity,strong adsorption,commonly used in many nutrients carriers,formulations,such as concentration of fat,vitamins,honey,perservatives,antioxidants and the like have a large number of applications.
G,Friction and Sealing Materials
Because vermiculite resistant high temperature and is a multi-layer sheet structure,high temperatures generated during use in friction ,sealing material,can make more than a single binder fibers,liquefaction,gasification,affecting the brake performance,adding vermiculite after the stone to prevent high-temperature heat recession,improve product strength,reduce noise,reduce the weight and cost of the prodcut .
H,In package materials
Because vermiculite lightweight,fireproof,strong adsorption is now widely used in hazardous chemical liquids,chemicals flowing liquid,seafood,water silkworm,fruits,bulbs,plant moss base block storage packaging,swimming pool,from soft,abrasion resistance,thermal insulation agaiinst the cold effect.
