Brick of pearlite heat preservation
Although pearlite applies at each domains widely, it is an industry that just promotes end moxa, but it already faced grim challenge in certain domain, before long in the future, a lot of material will replace pearlite. In substitute data side, use as plaster and the heat-insulating material that build a domain, piece shape vermiculite is a kind of the most competitive stuff. Light qualitative aggregate if: Floatstone, expand clay, shale and eruption cliff, eruption broken bits, or quenching water mud, their cost intensity of low, structure is high, exceed pearlite.
In adiabatic respect, fibre glass, mineral wool, diatomite, asbestine, fiber and plastic foam also are strong competitor. Have most among them representative is factory of insulation material of industrial city Hua Lan, have China's biggest pearlite to produce a workshop, have 2 to expand pearlite product line, the TPS system that produces process to use DCS system to use a firm undertakes operation of process control, real time and factory information unifinication to whole apparatus, among them with gas be fuel expand pearlite product line, it is country is the biggest expand the product line of pearlite product, produce raw material of pearlite filter aid technically. Sufficient take into account expands the main factor that pearlite quality is influence pearlite filter aid. Because expand,pearlite quality is stabilized, grain intensity is high, from go up at all the product quality that assured BN(AG) pearlite filter aid. Expand pearlite is used at filtering when material, although also use silica arenaceous, organic fiber and other material, but diatomite is main substitute material.
Use as of filling and additive still have farinaceous and steatitic, silica arenaceous, clay, diatomite and limestone. On agriculture, have vermiculite, marl and sawdust with what pearlite photograph contends. When pearlite makes sorbent, abrasive and additive get the most easily the challenge of all sorts of mineral goods. On refrigerant project, opaque gas collosol and a kind of film that form by aluminium and vitreous cloth can replace pearlite. To meet the challenge of other goods and material, pearlite and pearlite treatment industry should reduce manufacturing cost to improve goods performance above all, make full use of the advantage of its oneself develops the functional sex product with new development ceaselessly, be like:
Quality of product of light qualitative waterproof and adiabatic housing materials is light, not easy ageing, waterproof and adiabatic, comfortable at the high level body of building and body of light qualitative wall, wall of conduit heat preservation, refrigeratory is protected cold etc. Unit weight of product of plank of sex of compound light qualitative function is light, intensity is high, but cut becomes the different figure that fits spot need, the product with expensive flatness of the surface after polishing is handled.
Glassy building installs plaque its characteristic is to have superior physico-chemical performance, qualitative move is costly, adornment function good; its are mechanical the excel marble such as function, weatherability, glossiness is close to granite. The Zai Peiji that do not have earth is the applied field that agriculture, plant, horticultural respect has development outlook very much character. Filter aid, practice shows pearlite and diatomite are used, a kind of any filter aid use effect excel alone.
Brick of pearlite heat preservation develops a tendency
1) expands to rise the goods function of pearlite, should develop globose blame as soon as possible poriferous expand the development of pearlite. Enter furnace pearlite above all mine should be pressed as far as possible close the irregular shape; with the globose and appropriate granuality that is not before the 2nd it is the composition that improves kiln furnace, rise expand the intensity of pearlite.
Grinding of classics of 2) pearlite raw ore, exceed grinding and the mineral filling that exterior chemistry is handled and become a particular function, can apply at the industry such as balata, plastic, cable, paint, printing ink widely.
3) pearlite is used at animal feed to mix plant crop, already obtained initial effect, no matter be the matting in the additive that makes animal feed, coop makings, filling, prevent the additive that harden and improves liquidity, or the carrier that regards vet as preparation, insecticide, fertilizer, microelement, absorbefacient or adsorptive content, or use at depart to foster matrix and other purpose.
Anyhow, filter paper and filter aid, horticultural with filling use further, will make industry of our country pearlite jumps new chance to extricateoneself from an awkward position. Industry of our country pearlite has development outlook.
Current although pearlite applies at each domains widely, it is an industry that just promotes end moxa, but it already faced grim challenge in certain domain, before long in the future, a lot of material will replace pearlite. In substitute data side, use as plaster and the heat-insulating material that build a domain, piece shape vermiculite is a kind of the most competitive stuff. Light qualitative aggregate if: Floatstone, expand clay, shale and eruption cliff, eruption broken bits, or quenching water mud, their cost intensity of low, structure is high, exceed pearlite.
