ua Sintered ceramic xuab zeb rau foundry nrog txias tub ntxhais lub thawv - Shenghuo

Sintered ceramic xuab zeb rau foundry nrog txias tub ntxhais lub thawv

Lus piav qhia luv luv:

Cov txheej txheem lub thawv txias yog hais txog cov txheej txheem ua cov xuab zeb uas yog catalyzed / hardened los ntawm tshuab hauv cov pa roj los yog aerosol, thiab tsim instantaneously ntawm chav tsev kub.Txoj hauv kev zoo tshaj plaws yog txoj kev triethylamine, uas siv phenolic-urethane resin thiab ua kom tawv nqaij los ntawm tshuab triethylamine gas.Cov yam ntxwv ntawm cov txheej txheem no yog: cov xuab zeb tseem ceeb tuaj yeem siv tau ntev, lub sij hawm kos pwm luv luv, qhov kev ua tau zoo yog siab, thiab lub zog siv tsawg.

Cov txheej txheem lub thawv txias yog hais txog cov txheej txheem ua cov xuab zeb uas yog catalyzed / hardened los ntawm tshuab hauv cov pa roj los yog aerosol, thiab tsim instantaneously ntawm chav tsev kub.Txoj hauv kev zoo tshaj plaws yog txoj kev triethylamine, uas siv phenolic-urethane resin thiab ua kom tawv nqaij los ntawm tshuab triethylamine gas.Cov yam ntxwv ntawm cov txheej txheem no yog: cov xuab zeb tseem ceeb tuaj yeem siv tau ntev, lub sij hawm kos pwm luv luv, qhov kev ua tau zoo yog siab, thiab lub zog siv tsawg.

Diesel cav castings, xws li lub tog raj kheej blocks, lub tog raj kheej taub hau, noj thiab tso cov kav dej, thiab lwm yam., qee qhov muaj cov qauv ntawm cov tub ntxhais thiab cov chaw me me ntawm cov hlaws dai, uas ua rau muaj kev txhaj tshuaj cuav, tawg, thiab lwm yam., lossis cov hlab ntsha tuaj yeem tshwm sim hauv cov hlab ntsha. castings vim loj expansion ntawm silica xuab zeb.Qhov tshwm sim ntawm qhov tsis xws luag xws li cov xuab zeb nplaum thiab qhov pores kuj yog qhov siab.

Siv cov xuab zeb ceramic los yog sib tov ceramic xuab zeb thiab silica xuab zeb hauv kev faib ua feem, tus nqi ntawm cov resin ntxiv yog txo los ntawm 20-30%, thiab cov teeb meem saum toj no tau txhim kho.Nyob rau tib lub sijhawm, cov xuab zeb core muaj kev sib tsoo zoo, uas txo cov kev ua haujlwm ntawm casting tu.Raws li qhov tshwm sim, ntau thiab ntau lub cav diesel cav casting foundries tau txais yuav cov xuab zeb txias core box technology.
