High-alumina Poly lub teeb Rwb thaiv tsev cib, tseem muaj rwb thaiv qoob loo, yog insulating cov khoom siv refractory ua tsawg dua cov khoom siv al2o3 tsis tsawg tshaj 48%. High-alumina Poly lub teeb rwb thaiv tsev bibs tsuas yog siv bauxite clinker, ua ke nrog av nplaum li cov ntaub ntawv raw, tov nrog binders thiab sawdust. In order to improve product performance, fine powders of industrial alumina, corundum, sillimanite, kyanite, and silica are added to produce products with a volume density of more than 0.4g/cm3. Qhov kev ua haujlwm siab tshaj plaws nrog cov kev ua haujlwm siab tshaj plaws nrog Al2O cov ntsiab lus thiab ntim ntom ntom, feem ntau ntawm 1250 ~ 1350 degree, thiab qee tus tuaj yeem ncav cuag 1550 degree.
Lub High-Alumina Poly-Hnav Insulating Cib Txheej Txheem ROCK Txheej Txheem, kev npaj ua npuas ncauj, moulding, tshuab ziab khaub ncaws.
Cov khoom lag luam
1.Txoj kev ua npuas ncauj ntawm kev ua npuas ncauj. Foaming tus neeg sawv cev yog qhov tseem ceeb surfactant. Ua npuas ncauj yog ib qho kev cuam tshuam nrog cua hauv cov theem ua kua. Hauv cov kab ke no, huab cua yog theem dispersed thiab kua yog qhov nruab nrab dispersion rau npuas sib cais. Ib txheej adsorption yog tsim ntawm cov roj-kua interface. Qhov ntau dua cov kev ua si ntawm cov dej num, muaj zog dua cov txheej adsorption yog thiab lub zog ua kom muaj peev xwm adsorb cov khoom zoo. Qhov kev ruaj ntseg ntawm cov txheej txheem adsorption yog cuam tshuam nrog kev sib haum xeeb ntawm cov neeg sawv cev ua npuas ncauj. Tus lej pH ntawm cov tshuaj colloidal tsim los ntawm cov roj thiab kua kuj cuam tshuam rau kev ruaj ntseg. Tus neeg sawv cev PHO ntawm cov ua npuas ncauj siv los ntawm cov khoom siv feem ntau hauv Suav teb yog nruab nrab ntawm 8 thiab 9. Thaum ua npuas ncauj, cov npaus yog qhov ruaj khov. Nyob rau lub sijhawm no, tus neeg sawv cev ua npuas ncauj tuaj yeem ua kom muaj dej siab thiab khov kho nrog dej. Qhov zoo ntawm kev ua npuas ncauj tus neeg sawv cev feem ntau pom los ntawm peb qhov ntsuas tau ua tiav: Ua npuas ncauj kev ua npuas ncauj, kev sib cais dej sib txawv, thiab ua npuas ncauj ntau yam. Rosin xab npum feem ntau yog siv ua npuas dej. Nws txoj kev npaj yog: muab sib tov ntawm Rosin (31%), Naoh (62%) rau hauv cov alkali) rau hauv Rosin yog yaj tag nrho thiab siponified. Tom qab txias, ntxuav nrog ntsev dej {{}} lub sij hawm ntawm {}}} Ntxiv Rosin xab npum rau cov dej kub thiab do tusyees los ua ib lub rosin xab npum foamer. Alum lossis aluminium sulfate feem ntau yog siv ua npuas dej stabilizer. Cov kua dej kua dej yog tov nrog cov emulsion ntawm Rosin xab npum nyob rau hauv lub xeev kub, thiab cov sib tov yog diluted nrog dej ntws nrog 1}}}}}}}}}}}}}}}} parted hauv lub xeev no. Lub foamer nkag rau kev tsim khoom tseem yuav tsum tau ua kom huv nrog dej rau qhov ceev ntawm 1. 0-1. 10g / cm. Thaum nws muaj 0.5% Rosin xab npum (suav raws li Rosin), 0.5% Dej kua nplaum (suav nrog cov khoom siv tsis zoo thiab muaj hnub nyoog qhuav nrog lub ntim qhuav ntawm 0. {}. 05g / cm3.
2. Kev ua hom phiaj ntawm cov av nkos foam. Finely crushed khi av nplaum, High-alumina Clinker thiab tshuaj ntsuam sawdust tau tov nrog dej sib xyaw ua ntu zus los ua kev av nkos. Tom qab ntawd lawv tau sib xyaw nrog cov khoom ua npuas nyob rau hauv cov tov khoom siv sib npaug kom ua npuas av. Qhov piv tau ntawm ua npuas ncauj rau cov av nkos yog nyob ntawm lub ntim ntom ntawm cov khoom. Cov av nkos ua npuas ncauj nrog lub ntim ntom ntom ntawm {2}}. 51 ~ 1.2/1} {{{} g / cm3.
3.Hog-Aluminium poly lub teeb rwb thaiv tsev cib moulding. Lub cib pwm tuaj yeem yog cov pwm ntoo lossis cov hlau pwm. Qhov ua haujlwm saum npoo ntawm lub cib pwm yuav tsum yog tus thiab lubricated. Lub cib pwm muab tso rau ntawm pawg nkoj qhuav nrog ncoo ntawv thiab ua npuas av nkos yog txhaj. Txhawm rau tiv thaiv cov khoom los ntawm kev tsim cov npuas loj thiab cuam tshuam rau cov pwm loj, thiab cov av nkos yuav tsum tau txhuam nrog cov txiag ntoo.
4.Drying ntawm high-aluminium poly lub teeb rwb thaiv tsev cib. Tom qab pouring, qhuav cov pwm ntawm txog 40 qib rau 18 ~ 20h, thiab dab neeg thaum muaj kev sib txawv ntawm 3 ~ 5 hli qhib puag ncig lub cib pwm. Txuas ntxiv kom qhuav. Lub sijhawm no, qhov ntsuas kub tuaj yeem tsa mus rau 80 ~ 90 degree; Yog hais tias qhuav nyob rau hauv lub tshuab ziab khaub ncaws, lub inlet kub yuav tsum tsis pub tshaj 40 degree, thiab qhov hluav taws xob txias yuav tsum tsis pub tshaj 150 degree. Residual noo nyob rau hauv lub cib: Cov pob zeb txheem tsis ntau tshaj li 3%, thiab cov thwv cib loj tsis ntau dua li 1%. Kom qhuav yog ib txoj kev tseem ceeb. Yog tias nws tsis yog tswj kom zoo, cov kab nrib pleb, hauv qab crispness, concave core core, nplaum pwm, thiab poob npoo thiab fab poob thiab fab poob thiab fab poob.
5.Txawm ntawm high-alumina bolylight rwb thaiv tsev cib. Siv cov kab txuas rau sab-thauj khoom sab nrauv, tsim cov ncej nrog cov pob zeb Silica, thiab pawg cib hauv cov ncej. Qhov siab ntawm lub thav duab yuav tsum tsis pub tshaj 1.6m.
Nta thiab Kev Ua Haujlwm
High-alumina Poly-lub teeb yuag insulating yog ua los ntawm tshwj xeeb cov ntaub ntawv, ntxiv nrog rau cov qauv tsim nyog, ntxiv nrog poly-lub teeb thaiv kev hlawv txoj kev. Cov khoom lag luam muaj qhov zoo ntawm lub zog siab, zoo thermal poob siab ruaj khov, thiab kab tua hluav taws me me, thiab cov thermal me me. Lawv tuaj yeem yog cov dav siv hauv ntau cov roj muaj cov roj corroded (tsis yog corroded kua) thiab rwb thaiv tsev hauv metallurgy, tshuab, ceramics, kev lag luam tshuaj thiab lwm yam kev lag luam. Nws yog qhov zoo tshaj plaws cov khoom txuag hluav taws xob nrog kev ua haujlwm kub hauv qab 1400 degree.
