Resin Coated Ceramic Sand
Kev piav qhia
Cov xuab zeb ceramic yog siv rau hauv cov xuab zeb molding thiab core xuab zeb los ua lub plhaub pwm thiab lub plhaub plhaub muaj cov khoom ntawm qhov kub thiab txias tsis kam, tsis tshua muaj kev nthuav dav, yooj yim tawg, thiab cov pa roj tsawg, uas tuaj yeem tiv thaiv kom tsis txhob muaj qhov tsis xws luag hauv castings. Rau cov cores nrog cov duab tshwj xeeb, tuaj yeem daws qhov teeb meem uas xuab zeb tua tsis yooj yim rau kev cog lus. Nws yog cov xuab zeb ceramic siv hauv RCS txheej txheem.
Tag nrho cov xuab zeb ceramic yog siv los ua cov xuab zeb coated, thiab rov qab siv dua tom qab reclamation, uas tuaj yeem txhim kho qhov zoo thiab kev ua haujlwm ntawm cov castings, txo cov castings scrape tus nqi thiab cov nqi tsim khoom lag luam, cov nqi siv mus ntev yog qis dua qhov ntawd. ntawm silica xuab zeb. Yog li ntawd, nyob rau hauv xyoo tas los no, yuav luag tag nrho cov loj-scale coated xuab zeb nroj tsuag tau siv ceramic xuab zeb li raw cov xuab zeb los tsim coated xuab zeb.
Nta
• Ntau dua refractoriness —-rau cam khwb cia hlau nrog siab pouring kub (cam khwb cia hlau, alloyed cam khwb cia hlau, stainless hlau, thiab lwm yam)
• Siab zog thiab tawv—–los tsim cov cores nyuaj nrog cov ntu nyias.
• Tsawg thermal expansion—–kom tsis txhob muaj kev nthuav dav.
• Ua kom rov zoo dua—-kom txo cov xuab zeb pov tseg, kom txo nqi.
• Zoo heev flowability —–kom cov cores nyuaj.
• Kev siv qis dua--kev hloov pauv roj tsawg dua, cov nqi tsim khoom qis dua.
• Inert tshuaj yam ntxwv—– tuaj yeem siv rau hauv cov hlau uas nrov, suav nrog Manganese hlau.
• Lub sijhawm cia ntev dua.
