Xuab zeb casting: Xuab nrum casting feem ntau siv nyob rau hauv lub valve kev lag luam tseem tuaj yeem muab faib ua ntau hom xuab zeb xws lintub xuab zeb, qhuav xuab zeb, dej iav xuab zeb thiab furan resin tsis muaj-ci xuab zebraws li cov sib txawv sib txawv.
(1) Cov xuab zeb ntsuab yog cov txheej txheem moulding txheej txheem hauv uas bentonite yog siv los ua phau ntawv sau ua haujlwm. Nws cov yam ntxwv yog: Cov xuab zeb tiav pwm tsis tas yuav tsum tau kho kom qhuav, thiab cov xuab zeb muaj zog zoo dua, uas yooj yim rau cov duab ntxuav thiab ntog xuab zeb. Cov tshuaj moulding ntau lawm yog qhov siab, lub voj voog ntau ntau yog luv, thiab cov khoom siv kuj muaj qhov yooj yim rau cov txheej txheem sib dhos. Nws qhov tsis zoo yog: Cov khoom siv tau muaj kev tsis xws luag xws li cov duab puab tsaig, thiab cov xuab zeb zoo nkauj, tshwj xeeb yog qhov ua tau zoo sab hauv, yog qhov deb ntawm txaus.
(2) Cov xuab zeb qhuav yog cov qauv ua qauv siv av nplaum ua cov phau ntawv, thiab me ntsis bentonite tuaj yeem txhim kho nws lub zog ntub dej. Its characteristics are: the sand mold needs to be dried, has good air permeability and air dispersion, is not easy to produce defects such as sand washing, sand sticking, and pores, and the internal quality of the casting is also relatively good. Nws qhov tsis zoo yog: Cov khoom siv xuab zeb kom yuav tsum tau ua, thiab kev sib tw ntau yog yog ntev.
(3) sodium silicate silate sand yog moulding txheej txheem siv dej iav ua ib phau. Nws cov yam ntxwv yog: dej iav muaj cov haujlwm ntawm kev ua kom tau nyuaj tom qab ntsib CO2, thiab tuaj yeem muaj ntau yam zoo ntawm cov txiaj ntsig ntawm cov txiaj ntsig thiab cov kev ua tau zoo. Txawm li cas los xij, muaj qhov tsis zoo xws li plhaub tsis zoo, nyuaj rau hauv cov xuab zeb ntxuav rau cov khoom siv, thiab siv cov xuab zeb.
(4) Furan Resin Tsis Muaj-Ci Sand Moulding yog ib txheej txheem Casting nrog Furan Resin ua phau ntawv. Nyob rau hauv chav tsev kub, cov moulding xuab zeb tau kho vim muaj tshuaj lom neeg ntawm cov neeg ua haujlwm ntawm tus neeg kho tus sawv cev. Nws cov yam ntxwv yog: cov xuab zeb pwm tsis tas yuav tsum tau qhuav, uas muaj cov luv luv ua lub voj voog thiab txuag lub zog. Resin moulding xuab zeb yog qhov yooj yim rau kev cog lus thiab muaj kev sib raug zoo, thiab qhov tseeb yog tau yooj yim, thiab qhov tseeb tau yooj yim, uas tuaj yeem zoo txhim kho qhov zoo ntawm cov cuab yeej. Nws qhov tsis txaus ntseeg yog: Qhov ua tau zoo rau cov xuab zeb kuj tseem siab, lub chaw tsim khoom muaj qhov tsis muaj ntxhiab tsw me ntsis, thiab tus nqi ntawm Resin kuj tseem siab. Nws sib xyaw ua ke ntawm furan Resin tus kheej tus kheej-self-handlening sand tov khoom, ntxiv rau cov qos yaj ywm txuas ntxiv ua los ntawm cov xuab zeb txuas ntxiv ua los ntawm cov xuab zeb txuas ntxiv ua los ntawm cov khoom siv rawin txuas ntxiv los Sib tov thiab siv thaum twg los tau. Qhov kev txiav txim ntawm ntxiv ntau cov ntaub ntawv raw thaum sib tov Resin xuab zeb yog li nram no: (12-90s) - SAND (5) SAND HOM HOM CASTING txheej txheem: Precision Casting.
