Kev Txhais thiab Cov Yam Ntxwv ntawm Acrylic Enamel Paint
Xim acrylic enamel yog ib hom txheej uas acrylic resin yog cov khoom siv tseem ceeb rau kev tsim cov zaj duab xis. Feem ntau nws muaj kev tiv thaiv huab cua zoo heev, tiv thaiv kev xeb ntawm cov tshuaj lom neeg, thiab cov khoom dai kom zoo nkauj. Raws li cov txiaj ntsig tshawb nrhiav, xim acrylic enamel muaj cov khoom tiv thaiv kev xeb, tiv thaiv dej, thiab tiv thaiv roj zoo heev, thiab tuaj yeem tiv thaiv qhov chaw ntawm cov khoom los ntawm kev cuam tshuam thiab kev puas tsuaj ntawm ib puag ncig sab nraud. Tsis tas li ntawd, ua xim acrylic ob-component, xim acrylic polyurethane enamel siv cov tshuaj tiv thaiv ntawm -OH ntawm acrylic thiab -NCO ntawm polyurethane los txuas thiab kho cov zaj duab xis, thiab muaj kev tiv thaiv kev laus zoo heev, tiv thaiv dej ntxuav, cov khoom siv lub cev, kev kho xim, thiab khaws lub teeb.
Kev ua tau zoo ntawm cov xim acrylic enamel tiv thaiv dej
- Cov xim acrylic muaj cov yam ntxwv tsis pub dej nkag thiab tsim nyog rau cov xwm txheej uas xav tau kev tiv thaiv xeb thiab dej, xws li cov khoom siv hlau, choj, nkoj, metallurgy, thawv, tshuab tsim kho, ntau hom tsheb thauj mus los, thiab lwm yam. Tsis tas li ntawd, cov xim acrylic polyurethane kuj muaj cov yam ntxwv tiv thaiv dej thiab alkali, thiab tsim nyog rau cov lag luam uas muaj kev yaig heev.
- Cov xim pleev xim acrylic (xws li xim pleev xim acrylic magnetic, xim pleev xim acrylic polyurethane magnetic) yog ib hom xim pleev uas muaj cov yam ntxwv tsis pub dej nkag. Nws cov yam ntxwv tsis pub dej nkag ua rau nws haum rau cov xwm txheej uas xav tau kev tiv thaiv dej nkag, thiab tseem muaj cov txiaj ntsig xws li kev tiv thaiv xeb thiab kev laus.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm tsis pub dej nkag
Cov xim acrylic (tseem hu ua xim acrylic) muaj cov yam ntxwv zoo heev rau kev tiv thaiv dej, thiab qhov no tau siv dav thiab tau lees paub hauv kev lag luam tiv thaiv xeb. Cov hauv qab no yog kev tshuaj xyuas ntxaws thiab cov lus qhia siv:
Lub hauv paus ntsiab lus ntawm kev ua haujlwm tsis pub dej nkag
- Cov yam ntxwv ntawm cov khoom siv
Cov xim pleev acrylic siv cov acrylic resin ua cov khoom siv tseem ceeb los tsim cov zaj duab xis. Nws cov qauv molecular muaj cov yam ntxwv hydrophobic, thiab tom qab kho, nws tuaj yeem tsim cov zaj duab xis ntom thiab txuas ntxiv mus, ua rau tiv thaiv dej nkag mus tau zoo. Qee cov khoom kuj ntxiv cov roj hmab chlorosulfonated polyethylene lossis cov khoom hloov kho polyurethane (xws li acrylic polyurethane magnetic paint), ua rau nws tiv taus dej thiab tiv thaiv dej noo ntxiv.
Piv txwv li, cov dej-raws li acrylic emulsion los ntawm kev tsim pawg hydrophobic tshwj xeeb tuaj yeem tiv thaiv cov dej molecules los ntawm kev nkag mus rau hauv lub substrate tom qab ziab.
Cov khoom siv ua los ntawm cov kuab tshuaj (xws li xim pleev xim acrylic hlau sib nqus) muaj kev tiv thaiv dej zoo dua thiab tsim nyog rau cov chaw noo noo ntev.
- Kev txheeb xyuas kev ua tau zoo
Cov kev sim hauv chav kuaj pom tau tias tom qab muab cov xim acrylic enamel ntub rau 24 teev, tsis muaj qhov tshwm sim tev tawm lossis poob ntawm qhov chaw.
Hauv cov haujlwm sab nraum zoov (xws li cov choj, nkoj, thiab cov qauv hlau), nws lub luag haujlwm tiv thaiv dej tuaj yeem tiv taus kev yaig ntawm dej nag thiab dej hiav txwv, yog li ua rau lub neej ntawm cov khoom siv hauv av ntev dua.
