Yuav luag txhua cov nplaum hlau uas koj tuaj yeem pom hauv khw muag khoom yog qhov ruaj khov. Feem ntau, cov qauv kev sib koom ua ke raug rhuav tshem tsis yog hauv cov nplaum txheej, tab sis ntawm cov ciam teb ntawm cov hlau yuav tsum tau koom nrog. Yog li, lub zog ntawm cov nplaum nplaum feem ntau nyob ntawm qhov kev npaj ntawm qhov chaw.
Feem ntau cov txheej yog kis nrog ntau yam roj, nplai, xim residues, kab ntawm corrosion. Tag nrho cov no tuaj yeem raug tshem tawm ob qho tib si chemical thiab mechanically.
Ua ntej siv cov kua nplaum rau cov hlau, cov khoom tsis huv yog kho nrog cov kua qaub lossis alkalis, nrog rau cov tshuaj tshwj xeeb rau kev tshem tawm xeb thiab ntxuav. Qhov kev txiav txim ntawm cov kua qaub los yog alkali yog raws li qhov tseeb tias oxides raug rhuav tshem sai dua li cov khoom siv hauv paus. Kev tu tshuaj yog sai dua thiab tsis tshua kim dua li kev tu tshuab. Tsis tas li ntawd, ib txheej resistant yog tsim rau ntawm cov hlau nto, uas ua rau kom lub zog thiab durability ntawm cov nplaum sib koom.
Txoj kev ntxuav ntawm qhov chaw thiabua ntej siv cov nplaum nplaum.
Nyob rau hauv rooj plaub no, kev ua haujlwm yog ua los ntawm cov khoom siv abrasive (hlau txhuam, tshuab tua blasting, sandblasting lossis ntawv xuab zeb). Qhov tshwm sim saum npoo dhau los ua rougher, uas ua rau thaj tsam ntawm kev sib tshuam ntawm cov nplaum thiab cov hlau, yog li ntawd, lub zog ntawm kev sib txuas nce.
Hnub no muaj ntau yam nplaum rau cov hlau ntawm kev ua lag luam, uas muaj lawv tus yam ntxwv thiab muaj pes tsawg leeg.
Ib qho ntawm cov khoom siv yog polyvinyl acetate kua nplaum (PVA). Nws tso cai rau koj los ua haujlwm nrog ntoo, iav, hlau, tawv, fabrics, thiab lwm yam. Cov khoom siv yog siv rau hauv ib txheej nyias ntawm yav tas los degreased nto, uas yog nruj nreem compressed. Kev teeb tsa kua nplaum tshwm sim tom qab 20 feeb, ua kom tiav ziab tom qab ib hnub.
Xav tau thiab zoo li cov nplaum nplaum rau roj hmab thiab hlau, raws li "Moment". Nws tseem muaj peev xwm sib txuas cov ntoo, ceramic, yas, muaj kev xav, nruj PVC, thiab lwm yam. Cov khoom no yog tshuaj lom thiab flammable. Nws tsuas yog yuav tsum tau ua haujlwm hauv qhov cua zoo lossis qhib qhov chaw deb ntawm qhov chaw ntawm qhov hluav taws kub.
Cov khoom yog siv rau hauv ib txheej nyias ntawm cov chaw npaj, tuav rau ib lub hlis twg ntawm ib teev, thiab tom qab ntawd cov ntaub ntawv uas yuav tsum tau koom yog compressed rau ob peb feeb.
Yuav luag txhua tus paub txog epoxy kua nplaum, uas tseem tso cai rau koj los koom nrog hlau, iav, ntoo thiab lwm yam ntaub ntawv. Tsis tas li ntawd,Cov cuab yeej siv los kaw cov kab nrib pleb thiab qhov, nws tuaj yeem siv los ua cov kua roj vanish.
Cov nplaum hlau no yog roj thiab dej tiv taus thiab cov rwb thaiv tsev zoo. Cov tshuaj yog tshuaj lom. Nyob rau hauv rooj plaub ntawm kev sib cuag nrog daim tawv nqaij, nws yuav tsum tau ntxuav tam sim ntawd nrog dej sov thiab xab npum. Cov cuab yeej tsis tuaj yeem siv rau gluing cov khoom noj khoom haus. Cov nplaum nws tus kheej yog npaj siv cov resin thiab hardener nyob rau hauv cov khoom siv nyob rau hauv ib tug ratio ntawm 10 mus rau 1. Tom qab stirring rau 10 feeb, thov cov tshuaj nyob rau hauv ib tug nyias txheej, thiab ces txuas lawv. Ib nrab polymerization ntawm cov tshuaj yuav tshwm sim tom qab 4 teev, ua tiav hardening tshwm sim nyob rau hauv ib hnub.
