Putty thiab Platform yog cov ntaub ntawv tseem ceeb hauv kev tsim kho, siv rau kev tsim cov chaw du thiab kom muaj kev ruaj ntseg zoo. Cov kev ua tau zoo ntawm cov ntaub ntawv no tau cuam tshuam los ntawm lawv cov lus sib xyaw thiab cov ntxiv siv. Methyl Hydrotyl cellulose (MHEC) yog tus tseem ceeb ntxiv hauv kev txhim kho qhov zoo thiab ua haujlwm ntawm putty thiab plaster.
Nkag siab methyl hydrotyl cellulose (MHEC)
MHEC yog lub cellulose ether derived los ntawm cov xov tooj ntawm lub ntsej muag, hloov kho methylation thiab hydroxyethylation cov txheej txheem. Qhov kev hloov kho no uas cuam tshuam cov dej solubility thiab ntau yam khoom ua haujlwm rau lub cellulose, ua mHEC ib haiv neeg ntxiv hauv cov ntaub ntawv tsim kho.
Tshuaj lom neeg cov khoom:
MHEC yog tus cwj pwm los ntawm nws lub peev xwm los tsim kev daws teeb meem thaum uas yaj hauv dej.
Nws muaj cov yeeb yaj kiab zoo heev-tsim muaj peev xwm, muab cov txheej tiv thaiv uas txhim kho lub durability ntawm putty thiab plaster.
Lub cev lub cev:
Nws nce cov dej khaws cia ntawm cov khoom noj kom haum, kev sib luag, kev txhim kho kom raug thiab lub zog kev txhim kho.
MHEC COCALLS THIXOROPY, uas txhim kho cov haujlwm ua haujlwm thiab yooj yim ntawm kev thov ntawm putty thiab plaster.
Lub luag haujlwm ntawm MHEC hauv Putty
Putty yog siv los sau cov me me tsis zoo ntawm phab ntsa thiab qab, muab ib qho chaw du rau kev pleev xim. Qhov muaj kev sib txuam ntawm MHEC hauv cov qauv siv Putty muaj ob peb cov txiaj ntsig:
Txhim kho cov haujlwm ua haujlwm:
MHEC muab kev sib kis ntawm kev sib tw ntawm kev ua tiav, ua rau nws yooj yim rau kev xa tawm thiab kis cov kab mob kom yooj yim thiab tusyees.
Nws lub tswv yim thixotropic cia cov putty kom nyob twj ywm hauv qhov chaw tom qab thov yam tsis muaj sagging.
Kev ua kom cov dej ua kom tiav:
Los ntawm kev khaws dej, MHEC kom ntseeg tau tias lub putty tseem ua haujlwm tau ntev dua, txo qis kev pheej hmoo ua kom qhuav ntxov.
Qhov no txuas ntxiv lub sijhawm ua haujlwm tso cai rau kev kho kom zoo dua qub thiab smoothing thaum daim ntawv thov.
Cov ntawv nplaum zoo tshaj:
MHEC txhim kho cov khoom nplaum ntawm putty, kom ntseeg tau zoo rau ntau yam nkaus li hauv cov pob zeb ua vaj tse, gyrksum, thiab av cib.
Txhim kho adhesion minimizes qhov ntxim nyiam ntawm cov kab nrib pleb thiab kev tshem tawm lub sijhawm.
Nce detability:
Kev ua yeeb yaj kiab ua yeeb yam muaj peev xwm MHEC tsim ib qho kev tiv thaiv kev tiv thaiv uas txhim kho cov kav dej ntawm cov txheej putty.
Cov kev cuam tshuam no tiv thaiv qhov pib ntawm thaj chaw noo noo thiab ib puag ncig, ntev ntev lub neej ntawm daim ntawv thov Pickty.
Lub luag haujlwm ntawm MHEC hauv Plaster
Plaster yog siv los tsim cov chaw du, ruaj ntawm cov phab ntsa thiab nthab, feem ntau yog lub hauv paus rau kev ua tiav ntxiv. Cov txiaj ntsig ntawm MHEC hauv Plaster cov qauv yog qhov tseem ceeb:
Txhim kho kev sib txawv thiab ua haujlwm:
MHEC hloov pauv cov rheology ntawm plaster, ua rau nws yooj yim dua los sib xyaw thiab siv.
Nws muab cov qauv zoo nkauj, creamy uas ua kom cov ntawv thov du tsis muaj cov lumps.
Kev ua kom cov dej ua kom tiav:
Kev kho kom zoo ntawm plaster yuav tsum muaj cov dej noo txaus khaws cia. MHEC paub kom yooj yim uas tau siv cov dej kom ntev dua, tso cai rau kev ua kom dej ua tiav ntawm cov Maas hais.
Qhov no tswj tau tus txheej txheem kev tsim qauv zoo nyob rau hauv lub zog thiab ntau ruaj txheej plaster.
Txo cov kab nrib pleb:
Los ntawm kev tswj kom qhuav tus nqi, MHEC tsawg kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov qhov tawg uas tuaj yeem tshwm sim yog PLASTER tau nrawm heev.
Qhov no ua rau muaj kev ruaj khov thiab cov khoom siv sib txawv.
Zoo adhesion thiab cohesion:
MHEC txhim kho cov khoom nplaum ntawm plaster, kom ntseeg tau nws daim ntawv sib khi zoo nrog ntau yam substrates.
Txhim kho cohesion nyob rau hauv plaster matrix tau tshwm sim hauv kev ua kom tiav ntau dua thiab ntev ntev.
Kev Ua Haujlwm Txhim Kho Cov Txheej Txheem
Viscosity Transpification:
MHEC nce cov viscosity ntawm cov kua aqueous, uas yog qhov tseem ceeb hauv kev saib xyuas kev ruaj ntseg thiab homogeneity ntawm putty thiab plaster.
Cov nyhuv thickening ntawm MHEC kom paub meej tias cov mixtures nyob ruaj khov thaum lub sijhawm khaws cia thaum lub sijhawm tiv thaiv kab sib cais ntawm cov khoom siv.
Rheology tswj:
Lub thixotrostropic ntawm mHEC txhais tau tias PUTTY thiab plaster ua kom pom kev coj ua me me, ua kom muaj kuab vim li cas hauv qab (lub sijhawm ntawv thov) thiab rov qab ua viscosity thaum so.
Cov cuab yeej no tso cai rau cov ntawv thov yooj yim thiab kev siv dag ntawm cov ntaub ntawv, ua raws li qhov chaw sai uas yam tsis muaj sagging.
Zaj duab xis tsim:
MHEC ua ib zaj yeeb yaj kiab hloov tau thiab txuas ntxiv rau thaum ziab, uas ntxiv rau cov neeg kho tshuab zog thiab kev tawm tsam ntawm cov khoom siv putty thiab plaster.
Zaj yeeb yaj kiab no ua raws li kev thaiv kev tiv thaiv ib puag ncig xws li av noo thiab ntsuas kub, txhim kho lub hnub nyoog ntev ntawm kev ua tiav.
Ib puag ncig thiab kev khwv nyiaj txiag
Muaj Ntxiv Ntxiv:
Muab tau los ntawm cov ntaub ntawv ntawm ntuj ntuj, MHEC yog biodegradable thiab ib puag ncig phooj ywg additive.
Nws cov kev siv ua rau cov khoom siv kev tsim kho tshiab los ntawm kev txo cov khoom siv hluavtaws thiab txhim kho cov khoom xyaw ntuj.
Nqi-txiaj ntsig:
Kev ua tau zoo ntawm MHEC hauv kev txhim kho cov kev ua tau zoo ntawm Putty thiab Plaster tuaj yeem ua rau cov nqi txuag tau hauv lub sijhawm ntev.
Kev ua kom tiav durability thiab txo kev saib xyuas cov nqi uas cuam tshuam nrog kev kho thiab rov ua dua.
Zog Efficiency:
Txhim kho cov dej khaws cia thiab kev ua haujlwm txo qis kev xav tau kev sib xyaw ntau zaus thiab cov nqi kev hloov kho thiab cov nqi zog.
Cov txheej txheem kho tau zoo rau kev kho kom yooj yim los ntawm MHEC kom paub meej tias cov ntaub ntawv ua tiav lub zog tshaj plaws nrog kev siv zog me me.
Methyl Hydrotyl Cellulose (MHEC) yog ib qho tseem ceeb ntxiv rau hauv kev ua kom zoo ntawm putty thiab plaster kev ua tau zoo. Nws lub peev xwm los txhawb kev ua haujlwm, kev siv dej, kev ua yeeb yam, thiab kav ntev ua nws tsis tseem ceeb hauv kev tsim kho niaj hnub. Los ntawm kev txhim kho cov khoom siv sib xws, thiab tag nrho cov khoom zoo, thiab plaster, mHEC muaj txiaj ntsig zoo dua thiab muaj kev coj ua. Nws cov txiaj ntsig ib puag ncig thiab tus nqi-ua tau zoo ntxiv rau nws lub luag haujlwm yog qhov tseem ceeb ntawm kev tsim kho. Raws li kev tsim kho kev tsim kho txuas ntxiv mus hloov zuj zus, kev siv MHEC hauv kev ua kom muaj ntau yam ntxiv, kev nce qib hauv kev tsav tsheb hauv kev txhim kho tshuab thiab zoo.
