- Kev Zoo Nkauj: Cov xim sib txawv tuaj yeem sib xyaw raws li qhov xav tau los muab cov teebmeem pom sib txawv.
2. Cov Cheeb Tsam Siv Tau
Cov chaw siv ntawm cov txheej txheem epoxy hauv pem teb uas ntws los ntawm dej yog dav heev, suav nrog tab sis tsis txwv rau:
- Cov chaw tsim khoom lag luam: xws li kev tsim tshuab, cov chaw tsim khoom siv hluav taws xob, kev ua zaub mov, thiab lwm yam, muab cov plag tsev uas tsis yooj yim hnav thiab yooj yim ntxuav.
- Qhov chaw ua lag luam: xws li cov khw muag khoom loj, cov khw loj, cov chaw nres tsheb, thiab lwm yam, los txhim kho qhov zoo nkauj thiab kev nyab xeeb ntawm qhov chaw.
- Tsev Kho Mob thiab Chaw Kuaj Mob: Vim nws muaj cov tshuaj tua kab mob thiab yooj yim ntxuav, nws tsim nyog siv rau hauv kev kho mob thiab kev tshawb fawb.
- Chaw Nyob: Ntau tsev neeg xaiv cov txheej txheem epoxy hauv pem teb uas muaj dej ua kom zoo nkauj hauv pem teb hauv chav nres tsheb, qab nthab thiab lwm qhov chaw.
3. Kev siv tshuab ua vaj tse
Cov txheej txheem tsim kho ntawm cov txheej txheem epoxy hauv pem teb dej yog qhov yooj yim, feem ntau suav nrog cov kauj ruam hauv qab no:
1. Kev npaj nto: Xyuas kom av qhuav thiab huv, thiab tshem cov roj, hmoov av thiab cov khoom xoob.
2. Siv cov primer: Siv ib txheej ntawm cov primer kom txhim kho kev nplaum.
3. Kev tsim cov txheej nruab nrab: Siv cov txheej nruab nrab raws li qhov xav tau kom ua rau cov txheej tuab thiab tiv taus kev hnav.
4. Daim ntawv thov Topcoat: Thaum kawg thov cov topcoat los ua ib qho chaw du thiab zoo nkauj.
5. Kev Kho: Tom qab txheej txheej tiav lawm, nws yuav siv sijhawm ntev los kho kom nws cov kev ua tau zoo mus txog qhov zoo tshaj plaws.
