Hnav rwb thaiv tsev rwb thaiv tsev hluav taws cib yog siv dav hauv cov pa hluav taws. Daim ntawv thov ntawm lub teeb liab rwb thaiv tsev hluav taws cib tau ua tiav qee yam kev tiv thaiv hluav taws xob thiab kev tiv thaiv ib puag ncig hauv kev lag luam kub.
Hnav rwb thaiv tsev cib ci yog cov khoom siv rwb thaiv tsev uas muaj qhov tsis tshua muaj ntom ntom ntom, siab porosity, thiab tsis muaj thermal conductivity. Nws cov yam ntxwv ntawm kev ceev ceev thiab qis thermal conductivity ua rau nws irreplaceable hauv muaj cov khoom siv lub cev.
Cov txheej txheem ntau lawm ntawmHnav Rag thaiv rwb thaiv tsev hluav taws cib
1. Nyhav cov ntaub ntawv nyoos raws li qhov yuav tsum tau sib piv, zom txhua cov khoom siv rau hauv daim ntawv hmoov. Ntxiv dej rau silica xuab zeb kom ua kom slurry thiab preheat nws ntawm qhov kub ntawm 45-50 ℃;
2. Ntxiv cov khoom lag luam uas seem rau cov slurry thiab do. Tom qab ua tiav kev sib xyaw, ncuav cov kab sib xyaw ua ke rau hauv cov pwm thiab ua kom sov rau 65-70 ° C rau foaming. Lub foaming tus nqi yog ntau dua 40% ntawm tag nrho cov nyiaj. Tom qab ua npuas ncauj, khaws nws ntawm 40 ° C rau 2 teev.
3. Tom qab sawv twj ywm tseem, nkag mus rau hauv chav ua pa rau muab cub, nrog lub siab ntawm 1.2MPA, ib lub sijhawm ntsuas kub ntawm 190 ℃, thiab lub sijhawm ntsuas ntawm 9 teev;
4. Kev kub siab li kub, kub 800 ℃.
