Nodular Cast Iron Plhaub Casting Khoom

Tuam Tshoj OEM kev cai cam khwb cia hlau plhaub pwm casting khoom.

Plhaub moldingtxheej txheem tseem hu ua pre-coated resin xuab zeb casting txheej txheem, kub plhaub molding castings los yog cov txheej txheem casting. Lub ntsiab molding khoom yog pre-coated phenolic resin xuab zeb, uas yog kim tshaj li ntsuab xuab zeb thiab furan resin xuab zeb. Ntxiv mus, cov xuab zeb no tsis tuaj yeem siv dua.

Furan resin self-hardening xuab zeb casting txheej txheem ( txheej txheem nobake) siv cov furan cob coated xuab zeb los tsim cov pwm pwm. Tom qab sib tov cov xuab zeb qub (los yog cov xuab zeb reclaimed), kua furan resin thiab kua catalyst tusyees, thiab muab tso rau hauv lub thawv tub ntxhais (los yog xuab zeb lub thawv), thiab tom qab ntawd muab nruj nreem rau hauv pwm los yog pwm hauv lub thawv tub ntxhais (los yog xuab zeb). box) ntawm chav tsev kub. Tom qab ntawd cov pwm casting lossis casting core raug tsim, uas yog hu ua self-hardening txias-core box molding (core), los yog nws tus kheej-hardening method (core).

Vim hais tias cov pwm yog tsim nyob rau hauv chav tsev kub thiab tsis xav tau cua sov, tus kheej-hardening xuab zeb casting tseem hu ua tsis muaj-ci casting txheej txheem. Tus kheej-hardening txoj kev yuav muab faib ua acid-catalyzed furan resin thiab phenolic resin xuab zeb self-hardening txoj kev, urethane resin xuab zeb nws tus kheej-hardening txoj kev thiab phenolic monoester nws tus kheej-hardening txoj kev.

Raws li tus kheej-hardening txias thawv binder xuab zeb, furan resin xuab zeb yog qhov ntxov tshaj plaws thiab tam sim no feem ntau siv hluavtaws binder xuab zeb hauv Suav foundry. Tus nqi ntawm cov resin ntxiv rau hauv molding xuab zeb yog feem ntau 0.7% mus rau 1.0%, thiab cov nyiaj ntxiv resin hauv cov xuab zeb feem ntau yog 0.9% mus rau 1.1%. Cov ntsiab lus ntawm dawb aldehyde nyob rau hauv furan resin yog qis dua 0.3%, thiab qee qhov chaw tsim khoom tau poob qis dua 0.1%. Hauv cov foundries hauv Suav teb, furan resin self-hardening xuab zeb tau mus txog qib thoob ntiaj teb tsis hais txog cov txheej txheem tsim khoom thiab qhov zoo ntawm cov castings.

Qhov zoo ntawm Furan Resin Coated Sand Self-hardening Molding Casting:
1) Txhim kho qhov tseeb qhov tseeb ntawm castings thiab qhov chaw roughness.
2) Lub hardening ntawm pwm (core) xuab zeb tsis tas yuav ziab, uas tuaj yeem txuag hluav taws xob, thiab cov ntoo pheej yig lossis cov thawv yas thiab cov qauv siv tau.
3) Nws tus kheej-hardnening molding xuab zeb yog ib qho yooj yim rau compact thiab vau, yooj yim los ntxuav cov castings, thiab cov xuab zeb qub tuaj yeem siv tau thiab rov siv dua, uas txo cov kev siv zog ntawm cov tub ntxhais ua, qauv, xuab zeb ntog, tu thiab lwm yam kev sib txuas, thiab Nws yog ib qho yooj yim kom paub mechanization lossis automation.
4) Qhov loj feem ntawm resin hauv cov xuab zeb tsuas yog 0.8% ~ 2.0%, thiab cov nqi ntawm cov ntaub ntawv raw yog tsawg.

Vim hais tias tus kheej-hardening txoj kev muaj ntau yam ntawm cov saum toj no-hais tshwj xeeb zoo, tus kheej-hardening txoj kev tsis yog tsuas yog siv rau cov tub ntxhais ua, tab sis kuj siv rau casting molding. Nws yog tshwj xeeb tshaj yog tsim rau ib thooj thiab me me batch ntau lawm, thiab muaj peev xwm tsim cam khwb cia hlau, cam khwb cia hlau thiab non-ferrous alloy castings. Qee qhov chaw tsim khoom hauv Suav teb tau hloov cov av nplaum qhuav xuab zeb pwm, cement xuab zeb pwm, thiab ib nrab hloov dej iav xuab zeb pwm.
