Los ntawm kev tsim cov khoom siv txhuas tuag ua si rau cov khoom sib txuas thiab tom qab ntawd los ua molding, cov txheej txheem yog cov txheej txheem nyuaj thiab sib txuam, nrog ntau cov khoom siv raw, uas yog ib qhov txheej txheem txheej txheem. Casting tseem yog tus neeg tseem ceeb ntawm lub zog thiab cov ntaub ntawv, nrog hnyav ua haujlwm thiab kev ua qias tuaj ib puag ncig. Cov pa roj uas tso tawm thaum lub txheej txheem casting ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv, tab sis cov khoom sib txuas feem ntau tsis muaj teeb meem.
Piv txwv li, phenolic resin cov xuab zeb tsim cov roj av ua cov organic xws li formaldehyde thiab methanol thaum lub sij hawm kub siab casting, uas yog tsim kev puas tsuaj rau tib neeg kev noj qab haus huv thiab ua pa ib puag ncig. Lawv cov khoom sib txuas ua ke yog carbon dioxide thiab dej, uas tsis muaj kev puas tsuaj rau tib neeg. Yog li no, qhov no yog txoj hauv kev zoo los tshem tawm cov phom sij dhau kev tiv thaiv. Tam sim no, cov tuam txhab kev tiv thaiv ib puag ncig tuaj yeem lees tias qhov kuab paug rau ib puag ncig yuav luag xoom los ntawm cov txheej txheem kev tiv thaiv ib puag ncig. Thoob ntiaj teb, cov teb chaws muaj kev tiv thaiv ib puag ncig kev cai los tswj cov kev tiv thaiv ib puag ncig ntawm cov chaw lag luam foundry. Txoj Cai Kev Tiv Thaiv Ib Puag Ncig tsis hais tias aluminium tuag-casting kuab paug ib puag ncig, tab sis nws hais meej meej tias nws" tshaj li tus qauv paug muaj paug paug." Yog li ntawd, kev cuam tshuam rau ib puag ncig ntawm txhuas tuag ua si yog nyob ntawm seb koj cov pa paug paug ntau dua li tus txheej txheem. Tsuav kom dhau tus qauv dhau, Lub Chaw Haujlwm Tiv Thaiv Ib Puag Ncig tau tuaj yeem nrog nws, uas ua raws li kev cai lij choj. Tsis tas li nyob rau hauv Suav teb, raws li Tshooj 60 ntawm" Kev Tiv Thaiv Ib puag ncig kev tiv thaiv ntawm Cov Neeg' s koom pheej ntawm Tuam Tshoj," cov neeg nyob rau theem nroog thiab siab dua, dhau los ntawm cov chaw lag luam, cov tuam txhab, thiab lwm cov chaw tsim khoom thiab cov neeg ua haujlwm, tso cov pa phem ntau dua cov qauv paug tawm paug lossis tag nrho cov pa paug paug. Lub tuam tsev kev tiv thaiv ib puag ncig ntawm tsoomfwv tuaj yeem hais kom nws coj mus ntsuas xws li kev txwv kev tsim khoom thiab kev tsim khoom tawm rau kev txhim kho. Yog tias qhov xwm txheej loj, nws yuav tsum ceeb toom rau cov neeg pom zoo ntawm tsoomfwv kom pom zoo thiab tau txiav txim kom tsum lossis kaw kev lag luam.
Yog li no, kev cuam tshuam ntawm txhuas tuag ua si rau ntawm ib puag ncig yog qhov tseem ceeb tshaj plaws seb cov roj concentration ntau tshaj li tus qauv. Thaum pib ntawm kev tsim ntawm peb lub tuam txhab' s tuag casting rhiav, chav ua haujlwm kev tiv thaiv ib puag ncig yuav tsum tau nqa tawm ib puag ncig ntawm kev saib xyuas ib puag ncig thiab kev tiv thaiv ib puag ncig kev tsim kho. Txhua qhov tuag cov nrum pov tseg yuav luag xoom yuav cuam tshuam rau ib puag ncig. Peb kuj yog ib lub tuam txhab uas muaj kev paub txog lub luag haujlwm hauv zej tsoom thiab vam tias yuav ua lub luag haujlwm zoo hauv lub ntiaj teb puag ncig.
