Putty thiab Plaster yog nrov siv cov khoom siv hauv kev tsim kho kev tsim kho. Lawv yog qhov tseem ceeb rau kev npaj phab ntsa thiab ceilings rau kev pleev xim, npog cov kab nrib pleb, thiab tsim kom du, txawm tias muaj chaw. Lawv muaj feem ntawm cov khoom xyaw sib txawv suav nrog cov cement, xuab zeb, txiv qaub thiab lwm yam kev ntxiv los muab cov kev kawm tau zoo thiab cov yam ntxwv. MethylhydroxyLCelleculose (MHEC) yog ib qho ntawm cov khoom tseem ceeb siv hauv kev tsim cov zaub thiab plaster hmoov. Nws yog siv los txhim kho cov khoom ntawm hmoov, txhim kho lawv cov kev ua haujlwm thiab ua kom zoo rau lawv cov ntawv thov.
Cov txiaj ntsig ntawm kev siv MHEC los tsim cov putty thiab gypsum hmoov
MHEC tau muab los ntawm cellulose thiab tsim los ntawm cov txheej txheem tshuaj lom neeg. Nws yog dej-soluble compound dav siv raws li cov tuab, stabilizer thiab emulsifier hauv kev tsim kho. Thaum ntxiv rau putty thiab gypsum hmoov, mhec tsho tiv no, muab cov txheej tiv thaiv uas tiv thaiv lawv los ntawm clumping thiab tswm. Qhov no tsim tawm ntau dua, sib xyaw ua ke uas yooj yim rau kev ua haujlwm nrog thiab muab kev ua tiav zoo dua.
Ib qho ntawm cov txiaj ntsig tau txais txiaj ntsig ntawm kev siv MHEC hauv kev tso tawm thiab plasterers yog tias nws txhim kho lawv cov khoom siv dej-khaws cia. MHEC Absorbs thiab khaws cov dej noo, ua kom cov sib xyaw sib txuas tau siv tau thiab tsis qhuav sai. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv ib puag ncig kub thiab qhuav qhov twg cov sib tov nrawm tau ua tsis tau, ua rau muaj kev pom zoo ua tiav.
MHEC kuj tau txhim kho cov haujlwm ua haujlwm thiab lub sijhawm ua haujlwm ntawm kev tso cai thiab plaster. MHEC ua kev sib xyaw thiab thov kom sib xyaw ua ke los ntawm kev khaws cov dej noo thiab tiv thaiv cov sib tov ntawm ziab. Tsis tas li ntawd, MHEC tus du med cas, beatrter cov ntaub ntawv tso cai rau putty thiab stucco kis tau tusyees dhau ntawm qhov chaw tsis tau tawm ib qho tsis muaj qhov tsis muaj qhov flawless, ua tiav zoo nkauj.
Ntxiv rau kev txhim kho cov kev ntxhib los mos thiab kev ua haujlwm ntawm Putties thiab Plasters, MHEC tuaj yeem txhim kho lawv cov khoom sib raug zoo. Los ntawm kev sib sau txheej txheej tiv thaiv ib ncig ntawm cov khoom me me, MHEC kom lawv tau txais kev khi ua ke rau cov npoo lawv yog kev kho. Qhov no ua rau muaj zog dua, ntau dua cov chaw ruaj khov uas tsis tshua yuav tawg, nti lossis tev nyob rau lub sijhawm.
Lwm qhov txiaj ntsig zoo ntawm kev siv MHEC hauv Putty thiab plaster yog tias nws nce lawv txoj kev tiv taus huab cua thiab ya raws. Qhov no txhais tau tias thaum ib zaug tso tawm los yog stucco yog thov, nws yuav tiv thaiv kev puas tsuaj los ntawm huab cua thiab ya raws, kom ua kom ruaj khov thiab zoo nkauj ntev ntev.
Txhim kho cov zaub mov thiab gypsum siv MHEC
Txhawm rau kom ua kom tiav cov kev ua tau zoo ntawm putty thiab plaster hmoov, nws yog ib qho tseem ceeb kom paub meej tias MQECTEC yog siv nyob rau hauv cov protortions kom meej. Qhov no txhais tau tias siv tus nqi ntawm MHEC tuaj yeem ua tiav qhov kev xav tau thiab cov yam ntxwv ntawm lub putty lossis stucco yog tsim tawm.
Qhov uas ib puag ncig uas yuav cuam tshuam rau kev ua tau zoo ntawm putty thiab gypsum hmoov yuav tsum tau txiav txim siab. Piv txwv li, hauv ib puag ncig kub thiab qhuav MHEC yuav xav tau ntxiv kom ntseeg tau tias qhov sib xyaw tseem ceeb tseem tuaj yeem tsim nyog thiab xwm yeem.
Nws yog qhov tseem ceeb heev los xyuas kom meej tias zaub lossis stucco siv tau kom ntau rau qhov ua tau zoo. Qhov no txhais tau tias ua raws li cov neeg tsim cov lus qhia kom zoo zoo thiab ua kom cov sib xyaw kom sib xyaw tau zoo ua ntej siv. Ib qho ntxiv, cov cuab yeej tshwj xeeb yuav tsum tau ua kom ntseeg tau tias cov putty lossis stucco tau thov covyees thiab xwm yeem rau qhov chaw raug kho.
MHEC yog ib qho tseem ceeb uas siv nyob rau hauv kev tsim cov putty thiab plaster hmoov. Nws txhim kho cov khoom thiab cov khoom ntawm cov ntaub ntawv no, txhim kho lawv cov txheej txheem, kev ua kom dej, cov pa roj hmab thiab ya raws. Qhov no ua rau muaj ntau dua li qub, ruaj thiab ntxim nyiam ua tiav uas tsis tshua yuav tawg, nti lossis tev lossis tev dhau lub sijhawm. Txhawm rau kom ua kom tau zoo ntawm kev ua tau zoo ntawm putty thiab gypsum hmoov, nws yog ib qho tseem ceeb kom paub meej tias siv tau ntawm MHEC yog siv, noj rau hauv cov nyiaj ib puag ncig uas yuav cuam tshuam lawv qhov kev ua tau zoo. Ib qho ntxiv, nws yog ib qho tseem ceeb uas yuav tsum tau thov cov putty lossis stucco raug kom ua kom tiav nws cov kev ua tau zoo thiab ua tiav cov txiaj ntsig xav tau.
HEMC yog siv hauv cov cai hloov kho kom txhim kho nws cov khoom Hydroxyethyl methylulose (HEMC) yog cov tshuaj siv dav siv hauv kev tsim kho kev tsim kho. Nws yog qhov sib txuas ntawm cov haujlwm ua haujlwm, thixotrotropy, thiab lwm yam tam sim no, ib qho tshiab ntawm cellulose ether tau txais ntau dua thiab ntau dua. Dab tsi tau nyiam ntau dua yog hydroxyethy methylcellulose (mhec).
Ib qho ntawm qhov tseem ceeb tshaj plaws uas txiav txim siab qhov zoo ntawm cov khoom noj kom zoo yog qhov ua haujlwm ntawm kev sib xyaw. Tias 's yog li cas yooj yim xis mas yog ua kom sib xyaw, duab thiab chaw. Yuav kom ua tiav qhov no, cov tshuaj sib xyaw ua ke yuav tsum yog kua kom txaus kom nchuav thiab ntws tau yooj yim, tab sis nws kuj yuav tsum viscous txaus los tuav nws cov duab. MHEC tuaj yeem ua tiav cov cuab yeej no los ntawm kev nce qib ntawm cov cement, yog li kev txhim kho nws cov haujlwm ua haujlwm.
MHEC tuaj yeem ua kom nrawm qhov dej ntawm cov cement thiab txhim kho nws lub zog. Lub zog kawg ntawm kev hloov kho yog nyob ntawm cov dej uas siv los sib tov nws. Cov dej ntau dhau yuav txo tau lub zog ntawm cov cement, thaum lub sij hawm me me me me yuav ua rau nws nyuaj rau kev ua haujlwm nrog. MHEC pab khaws cov dej ntawm cov dej, yog li ua kom muaj kev ua kom muaj kev kub ntxhov ntawm cov cement thiab txhawb kev tsim cov nyiaj ntawm cov kev sib tw muaj zog ntawm Caas hais.
MHEC pab txo cov naj npawb ntawm cov cement tawg. Raws li txoj kev kho kom haumas, cov sib tov shrinks, uas tuaj yeem ua rau tsim kev tsim cov kab nrib pleb yog tias tsis tuaj yeem. MHEC txwv tsis pub muaj cov dej nyab no los ntawm kev tswj cov dej kom haum rau hauv kev sib xyaw, yog li tiv thaiv cov cement los ntawm kev tawg.
MHEC kuj ua raws li cov yeeb yaj kiab tiv thaiv ntawm cov ceg xis, tiv thaiv dej los ntawm kev nqus dej los ntawm qhov chaw. Daim yeeb yaj kiab no tseem yuav pab tswj thawj cov ntsiab lus noo noo ntawm cov cement, ntxiv txo cov caij nyoog ntawm kev tawg.
MHEC kuj zoo rau ib puag ncig. Ua ntej, nws yog biodegradable, uas txhais tau tias nws tsis nyob hauv ib puag ncig ntev. Thib ob, nws tuaj yeem pab txo cov kev ntseeg kom yooj yim yuav tsum tau ua hauv txoj haujlwm kev tsim kho. Qhov no yog vim MHEC nce cov kev ua haujlwm thiab viscosity ntawm cov xis mas, txo qhov xav tau rau cov dej sib tov ntxiv uas tsuas daws cov kev sib xyaw ua keasas.
Kev siv MHEC hauv Caas muaj ntau qhov zoo thiab tuaj yeem ua rau muaj kev pab ntau rau kev tsim kho kev tsim kho. Nws txhim kho kev ua haujlwm ntawm txoj kev ywj siab ywj siab, txo cov kab nrib pleb thiab lub zog xis, thiab ua raws li kev tiv thaiv kev tiv thaiv ntawm cov ceg xis. Ib qho ntxiv, MHEC yog qhov zoo rau ib puag ncig. Yog li ntawd, MHEC yog cov khoom muaj txiaj ntsig zoo rau kev tsim kho kev tsim kho raws li nws txhim kho qhov zoo ntawm xis mas thiab muab cov txiaj ntsig rau cov neeg ua haujlwm thiab ib puag ncig.
