Kev xaiv ntawm atmospheric qhov sib tsoo log
Oct 13, 2021
Lub atmospheric qhov sib tsoo log muaj qhov zoo ntawm tsis yooj yim rau kev thaiv, siab durability thiab muaj zog txiav muaj peev xwm. Nws yog qhov tsim nyog rau kev sib tsoo zoo ntawm cov hlau mos, yas, roj hmab, tawv thiab lwm yam khoom tsis yog xim hlau. Nyob rau tib lub sijhawm, nws muaj cov yam ntxwv ntawm cov cua sov sai sai, yog li nws muaj txiaj ntsig zoo hauv kev sib tsoo qee cov khoom siv hluav taws xob, cov khoom ua haujlwm nyias nyias thiab cov txheej txheem sib tsoo qhuav (xws li kev sib tsoo cemented carbide cov cuab yeej thiab cov cuab yeej siv tshuab qhia rails).
Txoj kev tsim khoom ntawm atmospheric qhov sib tsoo lub log yog qhov tseem ceeb tib yam li cov khoom siv sib tsoo sib tsoo log. Qhov txawv yog hais tias ib qho nyiaj ntawm pore enhancer yog ntxiv rau cov khoom xyaw, uas yog kiag li volatilized los yog kub hnyiab tawm ua ntej lub sintering ntawm lub sib tsoo log, uas ua rau cov pores loj.
Qhov ntau lawm ntawm atmospheric qhov sib tsoo log yog: feem ntau, carbide thiab corundum raug xaiv raws li abrasives, Piv txwv li, dub silicon carbide (c), ntsuab silicon carbide (GC) thiab dawb corundum (WA) feem ntau siv. Cov Abrasives muaj siab hardness, nkig thiab ntse, thiab muaj thermal conductivity thiab hluav taws xob zoo; abrasive particle loj (36 # ~ 180 #); daim ntawv cog lus (ceramic bond); hardness (G ~ m qib); puab (pas, khob, tais los yog tais, thiab lwm yam); pore loj (li 0.7 ~ 1.4mm).
