Dej tsis kam: Raws li cov emulsion tsis muaj dej, dej tsis kam yog qhov yooj yim tshaj plaws thiab tseem ceeb tshaj plaws.Feem ntau, emulsions nrog cov dej tsis zoo tuaj yeem ua kom cov xim zaj duab xis pob tshab thiab tsis yooj yim rau soften txawm tias tom qab soaked hauv dej ntev.Raws li kev txheeb xyuas lub cev zoo li qub, cov dej tsis kam ntawm lub teeb xiav emulsion zoo dua li cov mis dawb lossis liab lub teeb emulsion.Feem ntau, qhov me me ntawm qhov me me, qhov zoo dua cov dej tsis kam, thiab qhov loj ntawm cov particle loj tuaj yeem txiav txim los ntawm qhov tsos.: Qhov kev txiav txim ntawm qhov loj me: pob tshab> lub teeb xiav> lub teeb ntsuab> lub teeb liab> milky dawb.l Elongation: Qhov siab dua qhov elongation, qhov zoo dua qhov kev hloov pauv ntawm qhov kub thiab txias, thiab qhov loj dua cov kua-rau-hmoov piv.Yog li ntawd, qhov siab dua qhov elongation ntawm emulsion yuav muaj qhov zoo dua cov nqi-zoo.

Adhesion: Ib qho dej tsis zoo emulsion yuav tsum muaj cov nyhuv adhesion zoo nrog cov cement puag.Feem ntau, txoj hauv kev zoo tshaj plaws tab sis zoo tshaj plaws yog kom tau txais cov emulsion ntawm koj txhais tes, thiab tom qab ntawd cia nws qhuav lawm.Ntawm qhov tod tes, cov duab kos ntawm emulsion raug kuaj xyuas.Yog tias nws nyuaj rau rub tawm ntawm koj txhais tes, nws ua pov thawj tias qhov adhesion ntawm emulsion zoo dua.Lwm txoj hauv kev yog sib tov cov emulsion nrog cov cement, thiab tom qab ntawd ua rau saum npoo ntawm cov pobzeb., uas ua pov thawj tias qhov adhesion ntawm emulsion yog qhov tsis zoo.Yog tias cov emulsion zoo sib xyaw nrog cov cement thiab qhuav, nws tsis yooj yim rau shoveled.

Kev tiv thaiv ib puag ncig: Polymer waterproof emulsions yog txhua yam tsim los ntawm cov txheej txheem polymerization, yog li cov cuab yeej siv qib siab thiab cov qauv kev ruaj ntseg ncaj qha cuam tshuam rau kev ua haujlwm ntawm kev sib txuas.Rau emulsions nrog qis kev ua tau zoo, cov ntsiab lus monomer dawb yuav ib txwm siab, thiab cov ntsiab lus dawb monomer yuav ib txwm siab.Nws yog tshuaj lom.Qhov siab dua, qhov teeb meem ntau dua rau tib neeg lub cev.Feem ntau, cov ntsiab lus ntawm cov monomers dawb tuaj yeem txiav txim los ntawm qhov tsw.Ntawm qhov tod tes, nws yog ib qho yooj yim los tsim cov roj ammonia tom qab cov polymer tsis muaj dej thiab cov cement sib xyaw, txawm hais tias cov roj ammonia tsis muaj teeb meem rau tib neeg lub cev.Txawm li cas los xij, yog tias kev tsim kho tau ua nyob rau hauv chav dej kaw, hauv qab daus thiab lwm qhov chaw, vim yog huab cua tsis zoo, nws yooj yim ua rau lub concentration ntawm ammonia roj rau ib chav tsev siab dhau.Ua hauj lwm nyob rau hauv xws li ib puag ncig rau ib ntev lub sij hawm tuaj yeem yooj yim ua rau kub hnyiab ntawm qhov ntswg mucosa.

Huab cua tsis kam: Cov huab cua tsis kam ntawm polymer waterproofing yog zoo dua li ntawm polyurethane thiab styrene-butadiene roj hmab.Cov huab cua tsis kam ntawm acrylic emulsion yog qhov zoo, tab sis tus nqi siab dua li ntawm styrene-acrylic emulsion.Qhov sib txawv ntawm styrene-acrylic polymer emulsion thiab acrylic acid yog qhov sib txawv ntawm yellowing kuj, tab sis nyob rau hauv cov ntaub ntawv tsis muaj dej, styrene-acrylic polymer feem ntau yog siv Emulsion, tus nqi tsim nyog, huab cua tsis zoo.
