ua ntej. Ua ntej nkag siab tias yog dab tsiredispersible polymer hmoov.
Dispersible polymer hmoov yog hmoov polymers tsim los ntawm polymer emulsions los ntawm cov txheej txheem tshuaj tsuag kom qhuav (thiab xaiv cov khoom tsim nyog). Cov hmoov polymer qhuav hloov mus rau hauv ib qho emulsion thaum nws ntsib dej, thiab tuaj yeem dehydrated dua thaum lub sij hawm coagulation thiab hardening txheej txheem ntawm mortar, yog li ntawd cov polymer particles tsim ib tug polymer lub cev qauv nyob rau hauv lub mortar, uas yog zoo ib yam li cov txheej txheem ntawm kev txiav txim. cov polymer emulsion, uas tuaj yeem txhim kho cov cement mortar. cuam tshuam kev sib deev. Emulsion qhuav hmoov hloov mortar yog hu ua qhuav hmoov mortar (tseem hu ua qhuav mix mortar, qhuav mix mortar). Txij li cov hmoov qhuav tsis tas yuav xav txog emulsion formulation thiab stability zoo li polymer emulsions, ib qho me me ntawm admixture tuaj yeem ua rau mortar ua tiav cov khoom xav tau, thiab nws muaj qhov zoo ntawm kev ntim khoom yooj yim, khaws cia, kev thauj mus los thiab muab khoom dua li emulsions, antifreeze thiab tsis muaj. pwm kev loj hlob, qhov teeb meem ntawm cov kab mob nyob, thiab qhov zoo dua uas nws tuaj yeem ua rau hauv ib qho khoom siv nrog cov khoom sib xyaw ua ke xws li cov cement thiab xuab zeb, thiab tuaj yeem siv tom qab ntxiv dej.
Thaum ua ntawv thov, sib tov thiab ntim cov xuab zeb, xis mas, emulsion qhuav hmoov thiab lwm yam ntxiv additives ua ntej, thiab tsuas yog yuav tsum tau ntxiv ib tug npaum li cas ntawm cov dej thaum lub sij hawm tsim kho ntawm qhov chaw los ua kom qhuav hmoov mortar nrog kev ua tau zoo. Lub hauv paus ntawm kev tsim cov hmoov qhuav emulsion yog tias cov khoom siv polymer tom qab redispersion ntawm cov hmoov latex qhia qhov loj me me los yog qhov loj me me dispersion zoo ib yam li cov thawj emulsion polymer hais. Qee qhov kev tiv thaiv colloid xws li polyvinyl cawv yuav tsum tau ntxiv rau hauv emulsion, kom cov hmoov latex tuaj yeem rov xa rov mus rau hauv emulsion thaum nws tiv nrog dej. Tsuas yog nrog zoo dispersibility tuaj yeem ua cov hmoov latex ua tiav cov txiaj ntsig zoo tshaj plaws. . Lub dispersible polymer hmoov feem ntau yog hmoov dawb. Nws cov khoom xyaw muaj xws li:
Polymer resin: Nws yog nyob rau hauv qhov tseem ceeb ntawm cov roj hmab hmoov hmoov, thiab nws tseem yog lub ntsiab tseem ceeb ntawm redispersible polymer hmoov.
Additive (sab hauv): ua ke nrog cov resin, nws plays lub luag hauj lwm ntawm kev hloov cov resin. Additives (sab nraud): Cov ntaub ntawv ntxiv yog ntxiv los nthuav ntxiv kev ua tau zoo ntawm cov hmoov polymer dispersible.
Kev tiv thaiv colloid: ib txheej ntawm cov khoom siv hydrophilic qhwv rau saum npoo ntawm cov khoom siv rov ua dua tshiab latex hmoov, kev tiv thaiv colloid ntawm feem ntau redispersible latex hmoov yog polyvinyl cawv.
Anti-caking tus neeg saib xyuas: nplua ntxhia muab tub lim, feem ntau yog siv los tiv thaiv cov roj hmab cov hmoov los ntawm caking thaum lub sij hawm cia thiab tsheb thauj mus los thiab los pab txhawb cov ndlwg ntawm roj hmab hmoov (tso los ntawm cov hnab ntawv los yog tankers.)
Yuav ua li cas txheeb xyuas qhov zoo ntawm redispersible latex hmoov?
Method 1, tshauv method
Siv ib qho nyiaj ntawm cov kua roj hmab rov qab, muab tso rau hauv lub thawv hlau tom qab hnyav, kub txog li 500 degrees, tom qab sintering ntawm qhov kub ntawm 500 degrees, txias rau hauv chav tsev kub, thiab hnyav dua. Lub teeb yuag thiab zoo zoo.
Txoj kev thib ob, txoj kev sib cais
Siv ib tug npaum li cas ntawm redispersible latex hmoov thiab yaj nyob rau hauv 5 npaug ntawm cov dej, do zoo thiab cia nws sawv ntsug rau 5 feeb ua ntej soj ntsuam. Nyob rau hauv txoj cai, qhov tsawg inclusions nyob rau hauv lub hauv qab txheej, qhov zoo dua qhov zoo ntawm redispersible polymer hmoov. Txoj kev no yog qhov yooj yim thiab yooj yim ua.
Txoj kev peb, txoj kev ua zaj duab xis
Siv ib qho zoo ntawm redispersible latex hmoov, dissolve nws nyob rau hauv 2 lub sij hawm dej, do nws tusyees, cia nws sawv ntsug rau 2 feeb, do nws dua, ncuav cov tshuaj rau ntawm ib tug ca lub khob huv si, thiab tso lub khob nyob rau hauv ib tug ventilated ntxoov ntxoo. . Tshem tawm thaum qhuav tag. Saib xyuas cov yeeb yaj kiab polymer tshem tawm. High transparency thiab zoo. Tom qab ntawd rub me ntsis, nrog zoo elasticity thiab zoo zoo. Tom qab ntawd cov yeeb yaj kiab tau txiav mus rau hauv ib daim hlab, muab tso rau hauv dej, thiab pom tom qab 1 hnub, qhov zoo ntawm cov yeeb yaj kiab tsis yaj hauv dej. Txoj kev no yog lub hom phiaj ntau dua
