MethylhydroxyLCelleculose (MHEC) yog cov polymer compound dav siv hauv cov ntaub ntawv tsim tsev thiab muaj qhov tseem ceeb hauv kev siv puty. Nov yog cov txiaj ntsig tseem ceeb ntawm methylhydredoxyrcellcellcellose hauv putty daim ntawv thov:
1. Txhim kho kev tsim kho kev tsim kho
1.1 Txhim Txhim Kho Cov Kev Ruaj Ntseg
Methyl hydrotyl cellulose muaj cov dej khov kho, uas pab kom tus neeg thov lub sijhawm ntxiv los hloov kho thiab kov. Tsis tas li ntawd, cov dej zoo khaws cia txwv tsis pub kom qhuav tawm sai tom qab daim ntawv thov, txo txoj kev pheej hmoo ntawm kev tawg thiab xaum.
1.2 Txhim kho kev siv fluidity thiab kev ua haujlwm
MHEC muaj peev xwm txhim kho kom muaj lub fluty ntawm putty, ua rau nws yooj yim rau kev thov thiab kis. Qhov no tuaj yeem txo cov txhuam txhuam thiab npuas thaum lub sijhawm ua kev tsim kho thiab txhim kho cov khoom tsim kho thiab kev ua kom zoo nkauj ntawm lub putty.
1.3 Muab cov khoom zoo adhesion zoo
MHEC tuaj yeem txhim kho cov nplaum ntawm putty thiab substrate, ua kom muaj kev ruaj ntseg thiab ruaj khov ntawm txheej. Qhov no yog qhov tshwj xeeb tshaj yog rau kev tsim kho hauv cov nyom lossis qhov chaw siab khiav tawm, raws li nws tiv thaiv cov txheej puty los ntawm cov ntaub qhwv thiab tev tawm.
2. Txhim kho lub zog ntawm lub cev ntawm putty
2.1 Txhim Kho Kev Tiv Thaiv Tsis Tau
Vim tias cov dej khaws cia thiab cov nyhuv yas ntawm MHEC, lub putty tuaj yeem shrip tusyees thaum ua kom qhuav thiab tawg. Lub putty qhov yooj yog txhim kho, tso cai rau nws kom zoo dua yoog rau kev deformations me me hauv substrate yam tsis muaj kev tawg.
2.2 Txhim kho cov hnav tsis kam
MHEC txhim kho lub hardness thiab tawv ntawm lub putty, ua rau nws cov nplaim dej ntau dua. Qhov no yog qhov tshwj xeeb tshaj yog rau cov phab ntsa uas tau siv tas li lossis muaj kev sib txhuam, pab kom txuas ntxiv lub neej ntawm phab ntsa.
2.3 txhim kho huab cua tiv
MHEC hauv Putty tuaj yeem txhim kho nws cov huab cua tsis kam, tso cai rau nws kom tswj tau ruaj khov nyob rau txawv txav huab cua. Seb nws yog qhov kub thiab txias lossis huab cua muaj zog, ua kom muaj zog tuaj yeem tswj hwm nws cov khoom siv lub cev thiab tsis yooj yim los ntawm kev hloov ib puag ncig.
3. Txhim kho cov tshuaj ruaj khov ntawm putty
3.1 Txhim kho Alkali Kuj
Methyl hydrotyl cellulose tuaj yeem txhim kho cov alkali tsis kam txhim kho putty thiab tiv thaiv kev ua phem ua rau tshwm sim los ntawm cov tshuaj alkaline. Qhov no kom ntseeg tau tias lub putty khaws nws cov kev ua tau zoo thiab qhov tshwm sim thaum muaj kev sib cuag nrog cov khoom noj raws li cov cementitious.
3.2 Txhim kho cov tshuaj tua kab mob thiab cov khoom tiv thaiv kab mob antifungal
MHEC muaj qee cov tshuaj tua kab mob thiab tiv thaiv kev loj hlob ntawm cov kab mob thiab pwm thiab tsis tiv thaiv cov pob txha thiab tsw tau ntawm qhov chaw muaj sia. Qhov no yog qhov tshwj xeeb tshaj plaws hauv noo noo lossis noo ib puag ncig los pab ua kom phab ntsa huv si thiab huv si.
4. Kev tiv thaiv ib puag ncig thiab cov nyiaj pab nyiaj txiag
4.1 Kev tiv thaiv ib puag ncig cov yam ntxwv
Methyl Hydrotyl cellulose yog cov khoom siv ntsuab thiab ib puag ncig zoo uas tsis muaj tshuaj lom thiab tsis muaj teeb meem rau tib neeg lub cev thiab ib puag ncig. Nws cov kev siv tuaj yeem txo lwm cov tshuaj ntsuab muaj kev phom sij thiab txo cov pa phem ib puag ncig thaum lub sijhawm tsim kho.
4.2 Txo cov nqi
Thaum thawj tus nqi ntawm MHEC yuav siab dua, nws ua tau zoo hauv kev siv zaub mov tuaj yeem txo cov khoom siv thiab daim ntawv thov txo tus nqi tsim kho. Siv sijhawm ntev dua lub neej thiab tsawg dua kev saib xyuas kuj tseem ua tau lub sijhawm ntev ntawm kev khwv nyiaj tau los ntev.
5. Cov ntawv thov ntau
Methyl Hydulose tsis yog tsuas yog haum rau phab ntsa sab hauv, tab sis kuj tseem muaj cov kab sib tov sab nrauv, tab sis kev tawm tsam sab nrauv, thiab kev sib xyaw ua ke. Nws cov versatility thiab cov khoom tau zoo ua nws tsis tseem ceeb hauv kev tsim kho tshiab niaj hnub no.
MethylhydroxySylcellcellulose muaj qhov tseem ceeb hauv kev siv puty. Los ntawm kev txhim kho cov dej rov qab, kev tsim kho fluenticity, kev tsim kho thiab lub cev, MHEC tuaj yeem txhim kho kev tsim kho kev ua haujlwm thiab siv cov nyhuv ntawm putty. Tsis tas li ntawd, nws cov kev nyiam ib puag ncig thiab cov txiaj ntsig kev lag luam kuj tseem ua rau nws lub tsev zoo tshaj plaws ntxiv. Nrog kev txhim kho kev ua lag luam tas mus li ntawm kev tsim kho cov thev naus laus zis, kev thov cov kev cia siab ntawm MHEC hauv kev ua kom dav.
