Dab tsi yog Qhov Zoo Tshaj Plaws Ntawm Microcrystalline Pob Zeb?

Lub neej ntev ntawm pob zeb microcrystalline feem ntau yog nyob nruab nrab ntawm 15 thiab 30 xyoo, nyob ntawm qhov chaw ua haujlwm, kev tsim kho, thiab kev saib xyuas txhua hnub. Raws li cov xwm txheej zoo tshaj plaws (xws li cov xwm txheej qhuav, tsis muaj cov kua qaub thiab alkali corrosion, thiab tsis muaj khawb), siab - pob zeb microcrystalline zoo tuaj yeem kav ntev dua 25 xyoo. Txawm li cas los xij, kev cuam tshuam ntev rau cov dej noo, muaj kuab paug hnyav, lossis kev cuam tshuam sab nraud tuaj yeem ua rau nws lub neej luv dua li 10 xyoo. Lub ntsiab yog vim li cas rau qhov sib txawv ntawm lifespan nyob rau hauv cov khoom lub zog: Microcrystalline pob zeb yog tsim los ntawm tej yam ntuj tso inorganic cov ntaub ntawv sintered nyob rau hauv high kub, tsim ib tug ntom microcrystalline iav txheej ntawm nws nto. Cov txheej no muaj qhov zoo xws li xoom dej nqus, tsis muaj impurities, thiab siab compressive thiab flexural zog. Txawm li cas los xij, yog tias cov txheej txheem microcrystalline no puas lawm, cov khoom siv sab hauv yuav sai sai.
