Cov yam ntxwv ntawm cov txheej hauv pem teb yog dab tsi?

1, Pervinyl chloride cement pem teb txheej

Cov tshuaj pleev hauv pem teb Pervinyl chloride yog ib qho ntawm cov khoom siv thaum ntxov uas siv los ua cov roj hmab hluavtaws rau kev kho kom zoo nkauj hauv pem teb hauv tsev hauv Suav teb. Nws yog cov tshuaj pleev hauv pem teb uas muaj cov tshuaj yaj uas npaj los ntawm kev sib tov, sib tov, txiav, yaj, lim thiab lwm yam txheej txheem nrog pervinyl chloride resin ua cov khoom siv tseem ceeb, sib tov nrog me ntsis ntawm lwm cov resins, ntxiv qee qhov plasticizer, filler, pigment, stabilizer thiab lwm yam tshuaj. Cov tshuaj pleev hauv pem teb vinyl perchloride muaj cov yam ntxwv ntawm kev qhuav sai, kev tsim kho yooj yim, tiv taus dej zoo, tiv taus kev hnav zoo thiab tiv taus kev xeb tshuaj lom neeg. Vim tias nws muaj ntau cov kuab tshuaj organic uas yoo hloov pauv thiab yooj yim hlawv, yuav tsum tau them sai sai rau kev tiv thaiv hluav taws thiab kev tiv thaiv roj thaum npaj xim thiab txhuam kev tsim kho.

2, Chlorine-ib nrab emulsion txheej

Cov txheej chlorine-ib feem emulsion yog cov txheej dej-emulsion. Nws yog ua los ntawm vinyl chloride - vinylidene chloride copolymer emulsion ua cov khoom siv tseem ceeb rau kev tsim cov zaj duab xis, ntxiv me ntsis ntawm lwm cov kua nplaum hluavtaws (xws li polyvinyl cawv aqueous solution, thiab lwm yam) copolymer kua ua cov khoom siv hauv paus, ntxiv ntau yam xim, cov khoom sau thiab cov khoom ntxiv uas tau npaj los ntawm cov txheej. Muaj ntau hom txheej chlorine-ib feem emulsion, ntxiv rau cov txheej hauv pem teb, cov txheej phab ntsa sab hauv, cov txheej qab nthab, cov txheej qhov rooj thiab qhov rai, thiab lwm yam. Cov txheej chlorine-ib feem emulsion muaj qhov zoo ntawm tsis muaj saj, tsis muaj tshuaj lom, tsis kub hnyiab, qhuav sai, yooj yim tsim thiab nplaum zoo. Cov txheej yog ceev thiab du, thiab tsis depowder; Nws muaj kev tiv thaiv dej zoo, tiv thaiv dej noo, tiv thaiv kev hnav, tiv thaiv acid, tiv thaiv alkali, tiv thaiv corrosion rau cov tshuaj lom neeg dav dav, lub neej txheej ntev thiab lwm yam ntxwv, thiab cov zis ntau, tus nqi qis hauv cov emulsion, yog li nws muaj ntau yam kev siv rau kev kho kom zoo nkauj sab hauv thiab sab nraud ntawm cov tsev.

3, Epoxy resin txheej

Epoxy resin txheej yog ob yam khoom siv kho kom sov li qub uas muaj epoxy resin ua cov khoom tseem ceeb tsim cov zaj duab xis. Epoxy resin txheej muaj cov yam ntxwv zoo heev nrog cov txheej hauv paus, zaj duab xis txheej tawv, tiv taus kev hnav, tiv taus kev xeb tshuaj lom neeg, tiv taus roj, tiv taus dej thiab lwm yam khoom, nrog rau kev tiv taus kev laus thiab huab cua zoo heev, zoo nkauj, yog qhov kev txhim kho hauv tsev nyob rau xyoo tas los no, tiv taus kev xeb thiab cov txheej txheem sab nraud phab ntsa zoo dua.

4, Polyvinyl acetate cement pem teb txheej

Cov txheej txheej cement hauv pem teb polyvinyl acetate yog ib hom txheej hauv av uas tau ua los ntawm polyvinyl acetate dej emulsion, cov cement Portland ib txwm muaj thiab cov xim thiab cov khoom sau. Nws tuaj yeem siv rau kev kho kom zoo nkauj ntawm cov pem teb cement tshiab thiab qub, thiab yog cov khoom siv txheej hauv pem teb tshiab uas muaj dej. Cov txheej txheej cement hauv pem teb polyvinyl acetate yog ib hom txheej txheej organic thiab inorganic sib xyaw ua ke uas muaj cov qauv zoo, tsis muaj tshuaj lom rau tib neeg lub cev, kev ua haujlwm zoo hauv kev tsim kho, lub zog thaum ntxov thiab kev sib txuas ruaj khov nrog cov hauv paus hauv pem teb cement. Cov txheej txheej uas tsim tau muaj kev tiv thaiv kev hnav zoo heev, kev tiv thaiv kev cuam tshuam, xim zoo nkauj, qhov chaw ywj pheej, zoo li hauv pem teb yas.
