Air hole is heat insolation of heat preservation of heat preservation brick, be if arise,?

Interior of heat preservation product has many air hole, these stomatic action are heat preservation heat insolation, when the fire prevention that produces brick of production heat preservation and flame lay a finger on is adiabatic, common the means with way of convenient blister of kind in other words and attaint additive.
So that be hit into steam system to the middle of pug, have 2 kinds of kind:
1, with mechanical equipment means to mix hit into gas inside fluid, make the blister inside pug smooth with thickener subsequently;
2, add blowing agent to the middle of mixing juice, reagent of this kind of experiment is changed into steam system after interaction force, steam system makes pug is changed into porous material, be over with thickener smooth this is poriferous material.
Should store the aeriform bubble inside sanded oar should reduce the interfacial pulling force that mixes juice with respect to Wu, because this adds blowing agent commonly. Add inside Xiang Ni makings can digest the blame that draws water share to extend sexual raw material more very much, for instance cement grog, or it is mix into adds the crystallization that contains a lot of caky water, can smooth expanded plastics.

So that make sanded oar Peng loose, add carbonic acid body and acid to the middle of mixing juice kind or it is aluminous, metallic stuff and his experiment reagent, lend its chemical change and produce blister. So that exceed ground of this kind of eye, what abroad often chooses is limestone and hydrochloric acid, think they are the industrial chemicals of be to one's profit. Choose half water plaster of Paris and material of chemistry of other gel material as thickener. The pug of heat preservation brick is begun after condense fight impetuous and fire quickly. The handicraft of fire again all previous is made via machining, the appearance that makes its are had and norms.

The manufacturing technological process of brick of qualitative light heat preservation has 4 kinds commonly
Accretion of 1) burn oneself out law. Also call tinderbox to add a way. Join carbolic pink, wood chip to wait can burn material, make heat preservation brick has a certain wind gap after combustion.
2) expanded plastics law. Foaming agent, be like inattentive soap, add in slop to make insulation brick, make with bubble by mechanical equipment.
3) chemical law. Use the chemical variation that can create steam system moderately, the handicraft of heat preservation brick of a kind of poriferous structure gets in making heat preservation brick machine craft whole process, use limestone or plaster of Paris of square magnesian Shijia commonly, make epispastic gum with hydrochloric acid.
Standard of 4) porous material. With pure earth of natural concave and convex club or artificial complex are withered person grog of expanded plastics cement, 3 oxidation the poriferous construction raw material such as hollow ball makes 2 aluminium or zirconia qualitative brick of light heat preservation.

Fireproof the difference with heat preservation

1. adiabatic heat preservation is characteristic
Of adiabatic brick conduct heat coefficient is 350-25cw/m.k of average air temperature of 0.2 ～ 0.4(about) , of adiabatic brick conduct heat coefficient is about 1 (350-25c.w/m.k of average air temperature) , the heat preservation performance of adiabatic brick is better than the heat preservation function of adiabatic brick much.
2. is fireproof degree
The use temperature of heat preservation product is average under 1400 degrees, the fireproof sex of firebrick is 1400 degrees about.
3. opposite density
Adiabatic brick is heat-insulating material commonly, opposite density is 0.8 ～ normally 1.0g/cm3, the opposite density of adiabatic brick is 2.0g/cm3.
