Kev tiv thaiv dej: Ua ib yam khoom siv emulsion uas tsis ntub dej, kev tiv thaiv dej yog qhov yooj yim tshaj plaws thiab tseem ceeb tshaj plaws. Feem ntau, cov emulsion uas tiv thaiv dej zoo tuaj yeem ua rau cov xim pleev xim pob tshab thiab tsis yooj yim rau mos txawm tias tom qab raug dej ntev ntev. Raws li kev tshuaj xyuas lub cev zoo li qub, qhov kev tiv thaiv dej ntawm lub teeb xiav emulsion zoo dua li ntawm cov xim dawb lossis xim liab emulsion. Feem ntau, qhov me dua ntawm cov khoom me me, qhov zoo dua qhov kev tiv thaiv dej, thiab qhov loj ntawm cov khoom me me tuaj yeem txiav txim siab los ntawm qhov tsos. : Qhov kev txiav txim ntawm qhov loj ntawm cov khoom me me: pob tshab > teeb xiav > teeb ntsuab > teeb liab > dawb mis nyuj. l Kev ncab: Qhov siab dua qhov kev ncab, qhov zoo dua qhov kev ywj pheej qis-kub, thiab qhov loj dua qhov piv ntawm kua-rau-hmoov. Yog li ntawd, qhov siab dua qhov kev ncab ntawm cov emulsion yuav muaj kev siv nyiaj zoo dua.

Kev nplaum: Ib qho emulsion zoo uas tsis muaj dej yuav tsum muaj qhov nplaum zoo heev nrog lub hauv paus cement. Feem ntau, txoj kev ib txwm muaj tab sis zoo tshaj plaws yog kom tau txais cov emulsion rau ntawm koj txhais tes, thiab tom qab ntawd cia nws qhuav ntuj. Ntawm ib sab tes, qhov cuam tshuam ntawm cov emulsion raug kuaj xyuas. Yog tias nws nyuaj rau txhuam tawm ntawm koj txhais tes, nws ua pov thawj tias qhov nplaum ntawm cov emulsion zoo dua. Lwm txoj hauv kev yog sib tov cov emulsion nrog cement, thiab tom qab ntawd ua rau nws ntawm qhov chaw ntawm cov pobzeb. , uas ua pov thawj tias qhov nplaum ntawm cov emulsion tsis zoo. Yog tias cov emulsion zoo sib xyaw nrog cement thiab ziab, nws tsis yooj yim rau shoveled down.

Kev tiv thaiv ib puag ncig: Cov polymer waterproof emulsions yog tsim los ntawm cov txheej txheem polymerization, yog li cov khoom siv siab heev thiab cov mis ruaj khov ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov khoom sib xyaw. Rau cov emulsions uas muaj kev ua haujlwm tsawg, cov ntsiab lus dawb monomer yuav siab ntuj, thiab cov ntsiab lus dawb monomer yuav siab ntuj. Nws yog tshuaj lom. Qhov siab dua qib, qhov ntau dua rau tib neeg lub cev. Feem ntau, cov ntsiab lus ntawm cov dawb monomers tuaj yeem txiav txim siab los ntawm tsw. Ntawm qhov tod tes, nws yooj yim los tsim cov roj ammonia tom qab cov polymer waterproof thiab cement sib xyaw, txawm hais tias cov roj ammonia tsis ua rau tib neeg lub cev puas tsuaj. Txawm li cas los xij, yog tias kev tsim kho tau ua tiav hauv chav dej kaw, qab nthab thiab lwm qhov chaw, vim yog huab cua tsis du, nws yooj yim ua rau cov roj ammonia ib cheeb tsam siab dhau. Ua haujlwm hauv ib puag ncig zoo li no ntev tuaj yeem ua rau kub hnyiab ntawm lub qhov ntswg mucosa.

Kev tiv thaiv huab cua: Kev tiv thaiv huab cua ntawm cov polymer waterproofing zoo dua li ntawm polyurethane thiab styrene-butadiene roj hmab. Kev tiv thaiv huab cua ntawm acrylic emulsion 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 kev tiv thaiv daj, tab sis hauv cov ntaub ntawv tsis muaj dej, styrene-acrylic polymer feem ntau yog siv Emulsion, tus nqi tsim nyog, kev tiv thaiv huab cua zoo.
