Kev piav qhia txog khoom
Xim alkyd yog ib hom txheej uas nws cov khoom siv tseem ceeb yog alkyd resin. Nws cov haujlwm tseem ceeb suav nrog kev tiv thaiv xeb thiab tiv thaiv hluav taws, tab sis tsis yog txhua yam khoom muaj ob qho tib si. Nws cov yam ntxwv yooj yim suav nrog kev tiv thaiv huab cua zoo heev, tawv thiab lo. Cov khoom tseem ceeb yog polyester resin thiab diluent, thiab nws siv dav hauv kev lag luam xws li hlau, cov qauv hlau, thiab nkoj.
Kev Txheeb Xyuas Txog Kev Ua Haujlwm
Xim alkyd yog ib hom txheej polyester uas muaj cov khoom tseem ceeb xws li polyester resin thiab alkyd ester thinner. Nws muaj ob qho tib si tiv thaiv xeb thiab tiv taus hluav taws. Nws ua tiav kev tiv thaiv xeb los ntawm kev tsim ib daim zaj duab xis tiv thaiv rau ntawm qhov chaw hlau, thiab tom qab kho, nws tsim ib txheej zaj duab xis tawv. Nws ncua kev sib xyaw los ntawm kev tsim dej, roj acid, carbon dioxide, thiab nqus cov pa oxygen.
Kev Tshawb Fawb Txog Kev Ua Haujlwm Tiv Thaiv Hluav Taws
- Lub hauv paus rau kev muaj hluav taws kub tsis kam ua haujlwm
Cov txheej txheem tshuaj lom neeg: Tom qab kho, txheej zaj duab xis tso tawm cov pa roj uas tiv taus hluav taws (xws li carbon dioxide) thaum lub sijhawm hlawv thiab nqus cua sov, yog li ntawd tiv thaiv kev sib kis ntawm cov nplaim taws.
Cov xwm txheej siv: Hauv qee qhov kev lag luam thiab kev tsim kho, cov xim alkyd yog siv los txhim kho kev tiv thaiv hluav taws, xws li cov qauv hlau, choj, thiab lwm yam.
- Qhov sib txawv ntawm cov xim pleev hluav taws tshaj lij
Alkyd resin yog ib hom tshuaj pleev xim uas tiv taus hluav taws. Txawm li cas los xij, nws yuav tsum nco ntsoov tias qhov ua tau zoo ntawm kev tiv taus hluav taws ntawm cov xim alkyd ib txwm tsis muaj zog dua li cov xim tshwj xeeb uas tiv taus hluav taws.
Cov xwm txheej siv tau
Yuav ua li cas kom paub qhov txawv ntawm cov xim alkyd uas tiv taus hluav taws?
- Saib daim ntawv lo ntawm cov khoom:
Cov xim alkyd uas muaj daim ntawv lo meej tias "xim tiv taus hluav taws" lossis "hom tiv taus hluav taws" muaj cov yam ntxwv tiv taus hluav taws. Cov xim alkyd ib txwm tsuas yog hais txog kev tiv thaiv xeb xwb.
- Cov xwm txheej siv rau kev siv:
Cov xim alkyd siv rau ntawm phab ntsa thiab cov khoom ntoo yuav tsom mus rau kev tiv thaiv hluav taws, thaum cov uas siv rau ntawm nkoj thiab tshuab tsom mus rau kev tiv thaiv xeb.
Yog tias koj xav tau ua kom tau raws li ob qho tib si kev tiv thaiv xeb thiab kev tiv thaiv hluav taws yooj yim (xws li kev tiv thaiv xeb rau cov qauv hlau ib txwm muaj), xim alkyd yog qhov kev xaiv pheej yig; yog tias nws yog thaj chaw tiv thaiv hluav taws kub uas muaj kev pheej hmoo siab (xws li cov khw loj, qhov av), nws raug pom zoo kom siv cov tshuaj tiv thaiv hluav taws kub tshaj lij.
