Aluminium kev ua kom cov khoom siv fiber ntau cov khoom siv yog ua los ntawm cov khoom zoo calcined coke li cov khoom raw. Lawv tau melted thiab txau hauv cov hluav taws xob hluav taws xob kom ua cov paj rwb fiber ntau. Tom qab tshem tawm cov nplais pob, saum npoo yog ua tiav rau hauv fiber ntau cov khoom (muaj kev xav, pam vov, thaiv, thiab lwm yam). Vim tias nws lub teeb ntom ntom ntom ntom ntom ntom, uas yog 1 / {2}} / 6 lossis qis dua uas muaj peev xwm ua kom sov thiab zoo rwb thaiv tsev ua haujlwm. Nws yog cov khoom siv rwb thaiv tsev zoo. Nws yog dav siv hauv cov rwb thaiv tsev txheej ntawm ntau yam khoom siv thermal hauv methallurgy, Machinery, kev lag luam tshuaj, hwj chim thiab lwm yam kev lag luam.
(1) Recrystallization ntawm aluminium silicate freesic fiber tsim los ntawm cov txheej txheem kua dej los ntawm cov dej ua kua thiab maj mam txias rau hauv fiber ntau.
Thaum aluminium silicate fiber thiab nws cov khoom siv tau siv los ua cov khoom siv tawm lossis cov khoom siv hluav taws xob hluav taws xob ntawm cov khoom siv ua ntej ua ntej pib ntawm cov cua sov sab. Nrog rau kev nce ntawm cua sov lossis cua sov lub sijhawm, qhov tshwm sim cua sov maj mam tsim tawm mus rau nws txheej sab hauv.
Lub siab-dawb huv txhuas silicate fiber ua los ntawm high-purity fiber ntau ua los ntawm cov ntaub ntawv raw muaj ntau dua crystallization kub dua li qub txhuas silicate fiber. Yog li ntawd, siab-dawb huv txhuas site fiber muaj cov kub ua kom zoo thiab muaj kev ruaj khov hauv kev txo cov cua.
(2) Ua cov khoom siv high-brity aluminium silicate fiber ntau-kuj yog ua los ntawm cov fiber ntau, thiab qee tus kuj ntxiv cov nyiaj pub dawb B2O3 lossis ZUCTIVES me me. Nws tau melted nyob rau hauv ib lub rauv taws lossis kev tawm tsam kom tsim cov dej ruaj khov, thiab yog tsim los ntawm tshuab lossis kiv. Tag nrho cov ntsiab lus ntawm A12O {3+ Si02 nyob rau hauv kev lag luam aluminess thiab sillica xuab zeb siv yuav tsum muaj ntau dua 99%.
Muaj cov hmoov nplej alumina thiab silica xuab zeb tau sib xyaw ua ke hauv qhov hnyav piv ntawm 1: 1 thiab qhuav tov rau 4 mus rau 5 teev. Ib qho nqi ntawm cov dej thiab cov phau ntawv tsim nyog tau ntxiv rau qhov sib xyaw, thiab tom qab ntawd ces sib xyaw thiab nias rau hauv cov blocks siv lub cib xovxwm. Lub agglomerates tau calcined ntawm qhov kub thiab tawg rau hauv cov block nrog ib tug me me ntawm 20 txog 60 hli. Cov block tawg yog melted nyob rau hauv ib lub tshuab hluav taws xob arc thiab fiber ntau kom tau txais high-purity txhuas sithicate.
Qhov tau txais high-purity txhuas sixears Fibicate kuj tseem yuav ua ntxiv mus rau hauv ntau hom khoom ntawm cov khoom thib ob.
Cov txheej txheem ntawm kev ua cov pam vov ntawm rab koob txhuam ntawm aluminium silicate fiber ntau cov khoom lag luam ntawm cov ntaub ntawv tsis-woven hauv kev lag luam textile. Cov yam ntxwv ntawm hom no yog tias cov barbs ntawm rab koob xuas nrig ntaus tshuab siv. Thaum rab koob xuas nrig ntaus cov pam vov fiber ntau, cov fibers tau nqis, thiab thaum cov fibers tau muab coj los, kom cov fibers ntawm txheej yog intertwined. Yog li, lub zog ntawm cov ntawv fiber ntau yog txhim kho. Txawm li cas los xij, txij li cov fibractory tsis zoo li cov organic thiab muaj ntau nkas, cov fibers tau yooj yim thaum cov fibers thiab cov koob xaub ntim tau zoo rau rab koob. Txawm li cas los xij, vim muaj cov roj nplua nyeem, lub zog tensile ntawm daim pam tom qab koob xuas punching yog tsawg, yog li cov roj nplua nyeem yuav tsum tau muab tshem tawm.
