Yuav ua li cas yog puas dawb corundum feem ntau kho

Dawb corundumyog cov khoom tsim los ntawm kev lag luam alumina raws li cov khoom siv raw, nws muaj ntau qhov chaw tshwj xeeb, yog tias cov khoom no puas lawm, yog tias koj xav kho nws kuj xav xaiv txoj kev tshwj xeeb dua. Hauv qhov no, cov ntsiab lus hauv qab no yuav tsum tuaj yeem pab koj, uas suav nrog cov txheej txheem kho ntawm corundum dawb.
Dawb corundum nyob rau hauv kev ua, kev thauj mus los, kev siv thiab lwm yam txheej txheem yuav inevitably cuam tshuam los ntawm kev puas tsuaj, tab sis ntev li ntev raws li los ntawm infiltration, adhesion, tsim thiab lwm yam txheej txheem yuav ua rau nws rov qab. Tau kawg, qhov kev ua haujlwm tiag tiag tsis yog yooj yim, tab sis kuj nyob ntawm thaj chaw puas tsuaj tiag tiag, yog tias nws tsuas yog kho thaj chaw me me nrog kev npaj ua latex tuaj yeem ua tau.
Ua ntej ntawm tag nrho cov, 307 ib nrab rosin thiab styrene tau muab sib xyaw thiab nruab nrab raws li ib qho piv txwv, thiab tom qab ntawd nchuav rau hauv percompound cyclohexanone rau do, thiab tom qab ntawd ntxiv cobalt dawb corundum naphthoate los do qhov nruab nrab. Cov kuab tshuaj npaj tau txhaj rau hauv cov kab nrib pleb ntawm dawb corundum, thiab cov nyhuv ntawm adhesion tuaj yeem ua tiav thaum nws solidifying, yog li ntawd.dawb corundumtuaj yeem kho qhov qub qub.
