Cov cib hluav taws xob rwb thaiv tsev sib dua siv dav hauv cov qhov cub hluav taws xob rwb thaiv tsev. Kev siv cov cib hluav taws xob rwb thaiv tsev sib dua tau ua tiav qee yam kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig hauv kev lag luam kub siab.
Cov cib hluav taws xob rwb thaiv tsev yog cov khoom siv rwb thaiv tsev uas muaj qhov ntom ntom tsawg, porosity siab, thiab thermal conductivity tsawg. Nws cov yam ntxwv ntawm qhov ntom ntom tsawg thiab thermal conductivity tsawg ua rau nws tsis tuaj yeem hloov pauv tau hauv cov cub tawg kev lag luam.
Cov txheej txheem ntau lawm ntawmcib hluav taws xob rwb thaiv tsev
1. Ntsuas cov khoom siv raw raws li qhov sib piv xav tau, zom txhua yam khoom ua hmoov. Ntxiv dej rau hauv cov xuab zeb silica kom ua slurry thiab preheat nws ntawm qhov kub ntawm 45-50 ℃;
2. Ntxiv cov khoom siv raw seem rau hauv cov slurry thiab do. Tom qab sib tov tag, ncuav cov slurry sib xyaw rau hauv pwm thiab cua sov rau 65-70 ° C rau foaming. Qhov ntau ntawm foaming yog ntau dua 40% ntawm tag nrho cov nyiaj. Tom qab foaming, khaws cia rau ntawm 40 ° C rau 2 teev.
3. Tom qab sawv ntsug, nkag mus rau hauv chav ua kom sov rau kev ua kom sov, nrog lub zog ua kom sov ntawm 1.2MPa, qhov kub ntawm kev ua kom sov ntawm 190 ℃, thiab lub sijhawm ua kom sov ntawm 9 teev;
4. Kub siab sintering, kub 800 ℃.
