The applied step up of brick of light qualitative heat preservation. The blemish of brick of qualitative light heat preservation is fireproof sex can be differred, the advantage is character of long-term sex heat-resisting first-rate. Can alleviate in application of kiln body suttle, reduce cost then can, hoist the economy of the company income.
Kong Shigen vents his anger to wait for pumiceous makings to make according to adding tinderbox, epispastic glue or hollow ball in brick of qualitative light heat preservation, the norms that gives air hole is very big. This kind gives air hole not only the practical effect of adiabatic heat preservation is not tall, still endanger the physical property of handicraft. If vent bulk mark increases, many large hole will gather together, damage the compressive strength of insulation board. But, the accumulation density of qualitative light thermal insulation board is inferior, true density can be inferior. Accordingly, heat dependability is pretty good. After receiving effect of hot long-term sex, mildew of not easy generation changes.
Of brick of qualitative light tall aluminous heat preservation mineral form general component to be reached for dominant brilliant photograph help advance somebody's career matrix photograph two kinds. Amid advocate the action principal part that brilliant photograph is construction of qualitative light tall aluminous firebrick, its divide dissolve the point is high outside, return Wu to want a regulation to grow development is enough, in good condition nondestructive. Help advance somebody's career matrix that is to say advocate the inserts among brilliant photograph. Its number is not large, but component is multifarious, effect is distinct. 2 kinds this of qualitative light tall aluminous firebrick mineral form be short of one cannot.
Qualitative light tall aluminous firebrick secures immobile premise condition to fall in its composition, what all pledge because of what component spreads all over the gender reachs the craft that make is different, those who make handicraft of qualitative light tall aluminous firebrick form is mineral those who have size of type, gross, grain, shirt-sleeve case is different, what this kind of external economy constructs is different, cause the characteristic difference of heat preservation brick. For instance, qualitative light tall aluminous firebrick and zirconium corundum are qualitative tall aluminous firebrick, agree basically on composition, but its are mineral form different, because tall character is reached below this normal temperature of its handicraft,all have very big distinction. Say consequently, of qualitative light tall aluminous firebrick mineral form, the external economy of qualitative light tall aluminous firebrick is tectonic, it is the crucial essential factor of character of decision-making qualitative light tall aluminous firebrick.
Generally speaking, the constituent framework of qualitative light tall aluminous firebrick is the blame that by solid chemistry material and steam condition aperture form each other all bioplasm. Giving air hole is the crucial essential factor that target of tall function reachs below harm handicraft normal temperature, especially below tall standard, the resistance that outside making handicraft right, the ministry corrodes is reduced substantially. Giving stomatic generation to strand formerly is: The gas in the raw material when figuration of qualitative light tall aluminous firebrick stays after portion of raw material water of not complete and cleared; is cleared have calcination of raw material of interior space; not enough, the acerbity salt of a few Ying Rong solution is not complete and deliquescent, should the component of burn is not complete component of burn; raw material is not well-balanced, the furl when tall fire is not well-balanced wait.
But in a few qualitative light adiabatic heat preservation qualitative light tall aluminous firebrick makes in, great master is special still introduce a few spread all over a relatively well-balanced stoma. Go out to be put stomaticly have, the hole rate that endangered qualitative light tall aluminous firebrick instantly, moisture content, cubage is spent relative to density, permeability wait for index value.
Small hole pledges gently the character of each component in raw material of tall aluminous brick
Grog of tall aluminous aluminous cement: Show aluminous alumina is mineral namely the raw material after calcination of all previous classics, its key component is water aluminous stone and tall aluminium silica, have taller be able to bear or endure burn character, common will make take various tall aluminous firebrick, it is iron and steel industry and the fire prevention that other industry produces general application or preservative coating.
Aluminous acid is calcic: Aluminous acerbity calcium is a series of with 3 oxidation by hydrogenous oxidation calcium 2 aluminium are in the inorganic compound that tall issues to calcine and becomes, because of its intensity big, dissolve nods tall chemistry, be applied in concrete and fire fighting raw material. Structural style is MCaO · NAl2O3.
Does kaolinite exceed: of fine pink body? Qing of ⒄ of of Long of Bi of ⒏ of of Long of Bi of sieve of cadmium of Da of Bi Long washing with watercolors shakes ⒄ washs with watercolors umbrella of mallet of fine and soft of Qing course of study artisan of Х of of Щ of Mu Xun of of 8 Bi Long drips?SiO2-Al2O3-2H2O, its theory chemistry forms a key to be SiO2, Al2O3. Kaolin kind mineral vest in 1: 1 model Mei Lengyan aluminous silicate, crystallization is crucial by silicon oxygen tetrahedral form with hydric octahedron, amid silicon oxygen is tetrahedral join down 2 dimension azimuth the reseau that produces 6 sort pursues in order to be the same as the method with included angle each other layer. Sex of kaolin alkali resistance is strong, interpose report intensity is high, fireproof sex is tall, fireproof composition concerns degree of organic chemistry with kaolin, the fireproof sex of pure kaolin is 1700C about. When water Hei Shi is mixed when marble water content is higher, content of potassium, natrium, iron is higher, fireproof sex is reduced, fireproof sex is not less than 1500C.
Exceed particle gel of gas of 2 oxidation silicon: It is the accept rice technology that by many Si-O-Si ester radical photograph joins assemble arises three-dimensional Internet frame is tectonic, because of close infinite Duonami of technical aperture put have, solid state thermal convection current conveys down Kong Bian only, vent his anger indefinitely more nearly the wall comprised aperture to tend effectiveness of diameter of infinite appearance satisfy the need, make solid state coefficient of thermal conductivity fall to be restricted to basically little . Norms of its interpose aperture is 2 ～ 50nm, give air hole straight mediumly when raw material under 70nm when, the aeriform element structure inside aperture loses the working ability of optional fluidity, relativity ground conglutinate is in a stomatic wall, at this moment, aperture of accept rice technology lies circumstance of similar vavuum pump, the aeriform thermal convection current in raw material is abate be restricted to little . Because crucial component of gas is N2 and Co2, bureau region heat arouses the basis that do not have a law aeriform element structure surmounts doubt glue surface layer to develop effect of thermal convection current, cut off to heating up steady heat transfer to cause then effect.
Al2O3 exceeds fine pink: Al2O3 is the chemical material of a kind of tall tenacity, dissolve dot is 2054 ℃ , melting point is 2980 ℃ , common make fireproof insulation material at production.
Silicon pink: By pure natural calcite (SIO2) or melt quartz (SIO2) of preparation exceed fine powder, melt of classics high temperature, grinding, ball is ground (grinding of oscillatory, flow) , heavy medium, acerbity passivation is purified and high pure aqueous solution solidify. Silica gel pink is a kind of inorganic metalloid raw material that does not have smelly, free from contamination, have good hear resistance, corrosion resistance, diathermancy can poor, insulation property is good, elevatory stability of function of low, organic chemistry, performance is strong wait for an advantage.
Make aperture lotion: Make eyelet promotes tectonic antiseptic in raw material, see the chemical matter of the body that it is steam for Yi Rong commonly. The agent making hole that Wen Zhongzhong uses is carbon black of technology of rice of cassava starch, accept, crude oil one of anxious carbon or a few kinds mix up. This product relativity is current technical have dash forward the actual sex character that show and apparent progress, say actually, this product first will different gel of gas of silicon of the small pink of the grog of tall aluminous aluminous cement of particle size distribution, aluminous acerbity calcium, kaolin, Al2O3, silicon, agent that make hole, 2 oxidation and paper paddle water begin mix up, make make extraction base substrate every position component makes up supplement to agree, ensured the small orifice plate of calcination individual earning is tall the consistency of character of buy of everybody of brick of aluminous qualitative light heat preservation, a lot of water chestnut are contained in raw material additionally dash forward the stuff of particle size distribution that show, enlarged critical value particle size distribution, it is not easy that for small orifice plate grog of tall aluminous aluminous cement pledges brick of light heat preservation showed strong frame construction to make its are in applied whole process cause deformation.
Additional, the aluminous acerbity calcium that applies oneself to contain porous material reachs the agent that make hole and place to narrate raw material mix up, make ministry of raw material be between much inside make a lot of subtle give air hole, and afore-mentioned subtle those who give air hole to follow to calcine whole process not easily begin and assemble is grown, μ M level produces in commodity after and distributing to give air hole equably. Apply grog of tall aluminous aluminous cement, aluminous acerbity calcium, kaolin, Al2O3 severally be able to bear or endure burn characteristic and pretty good figuration sex to make make tall aluminium of extraction small orifice plate pledge brick of light heat preservation has Gao He soft, low stress is able to bear or endure flabbily, high thermal shock is characteristic.
