Ua thiab tiv thaiv txoj hauv kev ntawm cov xim stripping ntawm latex xim rau sab hauv thiab sab nrauv phab ntsa
1. Lub zog tsis txaus ntawm cov xim latex ua rau cov hmoov tshem tawm. Cov chaw tsim khoom lag luam dig muag txo tus nqi ntawm cov khoom siv raw, ua rau lub zog tsis zoo ntawm cov xim latex thiab me me ntxiv. Tshwj xeeb tshaj yog rau sab hauv phab ntsa putty, lub zog sib txuas tsis zoo.
2. Cov qauv tsim tsis tsim nyog. Teeb meem nrog kev xaiv cov khoom siv thiab cov qauv tseem ceeb heev hauv cov qauv putty. Piv txwv li, hydroxypropyl methylcellulose (HPMC) yog siv los ua cov tshuaj tsis muaj dej tsis zoo rau cov phab ntsa sab hauv. Txawm hais tias HPMC yog kim heev, nws tsis ua hauj lwm rau cov fillers xws li sulfate hmoov, talc hmoov, wollastonite hmoov, thiab lwm yam. Yog tias tsuas yog siv HPMC, nws yuav ua rau delamination. Txawm li cas los xij, CMC thiab CMS tsis tuaj yeem siv los ua cov dej tsis zoo lossis cov phab ntsa sab nrauv vim CMC thiab CMS hnov mob nrog cov hmoov calcium grey thiab cov cement dawb, uas yuav ua rau muaj zog. Hmoov thiab polyacrylamide kuj tseem ntxiv rau grey calcium hmoov thiab cov cement dawb ua cov txheej tsis muaj dej, uas tseem yuav ua rau cov tshuaj lom neeg ua rau cov hmoov tshem tawm.
3. Kev sib xyaw tsis sib xws kuj yog qhov laj thawj tseem ceeb rau kev tshem tawm ntawm sab hauv thiab sab nrauv phab ntsa putty. Qee cov tuam txhab lag luam thoob plaws lub teb chaws tsim cov xim latex nrog cov khoom siv yooj yim thiab ntau yam. Lawv tsis yog cov khoom sib xyaw tshwj xeeb. Kev sib xyaw tsis sib xws tuaj yeem ua rau cov xim latex tev tawm.
4. Kev ua yuam kev hauv cov txheej txheem ntau lawm ua rau cov xim latex tev tawm. Yog hais tias lub tov khoom tsis muaj ib tug tu muaj nuj nqi thiab muaj ib tug ntau ntawm residue, lub CMC nyob rau hauv dog dig putty yuav hnov mob nrog grey calcium hmoov nyob rau hauv waterproof putty. CMC thiab CMS nyob rau hauv cov phab ntsa sab hauv putty Nws yuav hnov mob nrog cov cement dawb ntawm sab nrauv phab ntsa putty thiab ua rau cov hmoov tshem tawm. Cov cuab yeej tshwj xeeb yog nruab nrog lub chaw nres nkoj tu, uas tuaj yeem ntxuav cov seem hauv lub tshuab. Qhov no tsis tsuas yog ua kom zoo ntawm putty tab sis kuj tso cai rau ib lub tshuab siv rau ntau lub hom phiaj. Koj tuaj yeem yuav ib qho khoom siv los tsim ntau yam putties.
