Redispersible latex hmoov yog ua los ntawm hluavtaws resin emulsion hloov los ntawm kev ntxiv lwm yam tshuaj thiab tshuaj tsuag-qhuav.Nws tuaj yeem tsim cov emulsion nrog dej raws li qhov nruab nrab dispersion thiab muaj redispersible polymer hmoov.
Txawm li cas los xij, muaj ntau hom latex hmoov nyob rau hauv kev ua lag luam, nrog rau cov nqi sib txawv thiab siab lossis tsis zoo.Nov yog qee txoj hauv kev yooj yim rau Xiaorun xaiv cov hmoov latex sai nrog kev ua tau zoo:

2. Zaj duab xis tsim pob tshab + yooj
Cov kauj ruam: Siv ib tug npaum li cas ntawm latex hmoov, dissolve nws nyob rau hauv 2 lub sij hawm tus nqi ntawm cov dej thiab do tusyees.Tom qab sawv ntsug rau 2 feeb, do rov sib npaug.Ncuav cov tshuaj rau ntawm ib daim iav huv uas muab tso rau hauv tiaj tus.Cov iav tau muab tso rau hauv qhov chaw cua thiab qhov chaw ntxoov ntxoo thiab qhuav tag Thaum kawg, tev nws tawm thiab saib xyuas cov tev tawm cov yeeb yaj kiab polymer.Qhov siab dua qhov pom ntawm cov hmoov latex, qhov zoo dua.Tom ntej no, koj tuaj yeem ncab nws me ntsis.Cov hmoov latex nrog zoo elasticity yog qhov zoo.
3. Huab cua tsis kam
Cov kauj ruam: Siv ib qho nyiaj ntawm cov hmoov latex, dissolve nws nyob rau hauv tib qho kev faib ua feem ntawm cov dej thiab do tusyees, ncuav cov tshuaj rau ntawm ib lub khob huv si, muab lub khob tso rau hauv ib qho chaw ventilated thiab ntxoov ntxoo, tom qab nws qhuav tag, tev nws tawm. , thiab txiav cov zaj duab xis rau hauv ib lub strips zoo, soaked nyob rau hauv dej, thiab soj ntsuam tom qab 1 hnub, nws tau pom tias qhov zoo ntawm latex hmoov kuj zoo yog hais tias nws yog tsawg yaj nyob rau hauv dej.
Daim ntawv ceeb toom
Qhov no tsuas yog ib qho yooj yim thiab yooj yim nrhiav txoj kev, uas yog siv los soj ntsuam cov khoom sai sai nrog purity / zoo.Cov txiaj ntsig siv zaum kawg tseem yuav tsum tau sim los ntawm cov cuab yeej kev sim ua haujlwm thiab ntxiv rau hauv mortar rau kev txheeb xyuas zaum kawg.
