1.High -kub yam ntxwv stability: Cov ntsiab lus siab dua mullite txhim kho thermal poob siab, thiab siab sintering ceev tiv thaiv deformation lossis spalling ntawm qhov kub siab, ua kom ruaj khov ua haujlwm ntawm 1300-1400℃dhau sijhawm ntev. |
2.Zoo heev tiv thaiv tshuaj tua kab mob: Cov ntsiab lus SiO₂ siab (60-70%) imparts inherent acid kuj; ntom microporous qauv inhibits tob tob ntawm slags thiab alkaline tshuaj; sintered saum 1400 degree, txhim khu kev ruaj ntseg ntawm cov qauv sab hauv. |
3.Tsawg thermal conductivity thiab rwb thaiv tsev zoo heev: Microporous qauv tsim cov txheej txheem huab cua zoo; Qhov nruab nrab ntom ntom sib npaug tiv thaiv tshav kub thiab rwb thaiv tsev, txo cov khoom siv hluav taws xob thiab cov nqi tsim khoom. |
|
4.Zoo heev mechanical zog thiab hnav tsis kam: Chav-kub compressive zog yog li ntawm 25 txog 45 MPa; ntom sintering kom ntseeg tau siab hnav tsis kam thiab tsis kam rau pulverization. |
5.Tus nqi siab -kev ua tau zoo thiab kev tsim kho yooj yim: Tus nqi qis dua li cov khoom siv zoo xws li siab -alumina thiab corundum cib; qis installation thiab txij nkawm nqi; standardized qhov ntev pab kev tsim kho sai; ntev kev pab cuam lub neej nrog luv txij nkawm cycles. |
6. Ib puag ncig tus phooj ywg, ruaj khov, thiab muaj ntau yam: Tsim nyog rau kev siv ib leeg lossis ua ke nrog cov alumina cib siab, refractory castables, thiab cov ntaub ntawv rwb thaiv tsev; kev cai- cov cib zoo li tus tuaj yeem tsim kom haum cov khoom siv geometries, ua kom haum thiab ua rau lub neej ntev. |
Hluav taws kub av nplaum cib yog cov khoom me me acidic refractory, resistant rau acidic slags thiab gases, tab sis tsawg resistant rau alkaline tshuaj. Lawv muaj qhov zoo siab -kub tsis kam thiab tiv taus cua sov thiab cua txias sai. Lawv cov refractoriness yog piv rau silica cib, xws li ntawm 1690 mus rau 1730 degree, tab sis lawv load softening kub yog tshaj 200℃qis dua silica bricks, vim muaj ze li ntawm ib nrab qis -melting- taw tes amorphous iav theem nrog rau siab -refractory.
Nyob rau hauv qhov kub thiab txias ntawm 0-1000 degree, ntim expands uniformly, nrog ib tug ze li ntawm linear expansion tus nqi ntawm 0.6-0.7%, roughly ib nrab ntawm silica bricks. Tshaj li 1200 degree, cov cib pib ntsws los ntawm lawv qhov siab tshaj plaws nthuav dav, raws li qis -melting- cov ntsiab lus ntawm cov khoom maj mam yaj thiab cov khoom yog tuav ua ke los ntawm qhov nro. Residual shrinkage yuav ua rau mortar sib koom ua ke loosening thiab tawg, uas yog ib qho tseem ceeb txwv ntawm av nplaum cib.
Ua los ntawm cov av nplaum refractory nrog 40-48% Al₂O₃, hluav taws av nplaum cib yog siv dav hauv cov khoom siv hluav taws xob xws li fais fab boilers, cement thiab txiv qaub kilns, chemical kilns, coking kilns, blast furnaces, thiab iav kilns, nrog rau hauv siab - cov khoom siv kub kub xws li cov khoom siv hluav taws xob hluav taws xob, hluav taws xob hluav taws xob, hluav taws xob thiab hluav taws xob. steel casting chaw.

●Ntim thiab Kev Tswj Xyuas Zoo:
Txhawm rau kom ntseeg tau tias cov av nplaum hluav taws tsis zoo thaum lub sijhawm thauj mus los thiab khaws cia, lub tuam txhab ntiav cov khoom ntim khoom muaj zog thiab cov txheej txheem tuav cov txheej txheem. Txhua batch tau soj ntsuam qhov pom thiab qhov loj me ua ntej ntim.
●Kev txhawb nqa ntim rau kev xa khoom txawv teb chaws:
Rau cov neeg siv khoom thoob ntiaj teb, muaj ntau yam kev xaiv ntim khoom ntxiv, suav nrog fumigated ntoo crates, steel -stripped thav duab, thiab cov pallets ntxiv. Cov no yog tsim los tiv thaiv kev vibrations, raug ntsev, thiab lub thawv thauj khoom siab thaum lub sij hawm ntev - kev thauj mus los hauv hiav txwv, kom cov khoom tuaj txog nyab xeeb.
●Kev Thauj Mus Los:
Tsim nyog rau lub tsheb thauj khoom, thawv, lossis pallet forklift thauj, tag nrho cov ntim tau dhau los ntawm kev poob siab -kev sim tiv thaiv kom tsis txhob tawg lossis lub kaum sab xis puas thaum tuav.
●Kev Cia Siab:
Khaws rau hauv qhov chaw qhuav, zoo- qhov cua nkag hauv tsev nrog cov pallets lossis cov plag tsev kom tsis txhob muaj dej los yog av noo, kom ntseeg tau tias cov khoom ua tau zoo.
