HPMC hauv cov hmoov qhuav mortar

Hydroxypropyl methylcellulose hauv cov hmoov qhuav mortar, qhov ntxiv ntawm cellulose ether yog qis heev, tab sis nws tuaj yeem txhim kho kev ua tau zoo ntawm cov ntub mortar, thiab nws yog ib qho khoom siv tseem ceeb uas cuam tshuam rau kev ua tau zoo ntawm cov mortar.

Hydroxypropyl methylcellulose Cov cellulose ether siv rau hauv cov hmoov qhuav mortar feem ntau yog hydroxypropyl methylcellulose ether (HPMC). Hauv cov honeycomb ceramics tshiab, nws tuaj yeem muab lubricity rau qhov dawb paug. Hauv kev lag luam txheej, nws tuaj yeem siv ua cov khoom tuab, cov khoom tawg thiab cov stabilizer hauv kev lag luam txheej, thiab muaj kev sib raug zoo hauv dej lossis cov kuab tshuaj organic. Ua cov xim tshem tawm. Luam ntawv number case: Nws yog siv ua cov khoom tuab, cov khoom tawg thiab cov stabilizer hauv kev lag luam number case, thiab muaj kev sib raug zoo hauv dej lossis cov kuab tshuaj organic. .Plastic: siv ua tus neeg sawv cev tso tawm, cov khoom mos, cov roj nplua nyeem, thiab lwm yam. Polyvinyl chloride: Nws yog siv ua cov khoom tawg hauv kev tsim cov polyvinyl chloride, thiab yog tus neeg sawv cev tseem ceeb rau kev npaj PVC los ntawm kev ncua polymerization. Hydroxypropyl methylcellulose Lwm tus: Cov khoom no kuj tseem siv dav hauv tawv, cov khoom ntawv, txiv hmab txiv ntoo thiab zaub khaws cia thiab kev lag luam textile.

HPMC hauv cov hmoov qhuav mortar feem ntau ua lub luag haujlwm ntawm kev khaws dej, ua kom tuab thiab txhim kho kev ua haujlwm ntawm kev tsim kho. Kev khaws dej ntau ntawm cov mortar tsim kho thiab cov xuab zeb plastering tuaj yeem ua rau cov cement hydrate tag nrho thiab ua rau lub zog sib txuas ntxiv. Tib lub sijhawm, nws tuaj yeem ua rau lub zog tensile thiab shear zog nce ntxiv, txhim kho cov txiaj ntsig ntawm kev tsim kho thiab txhim kho kev ua haujlwm zoo. Tiv taus dej thiab roj hauv putty, hydroxypropyl methylcellulose cellulose ether feem ntau ua lub luag haujlwm ntawm kev khaws dej, kev sib txuas thiab lubrication, zam kev tawg thiab dehydration los ntawm kev poob dej ntau dhau, thiab tib lub sijhawm txhim kho qhov adhesion ntawm putty thiab txo lub sijhawm tsim kho. Qhov tshwm sim nruab nrab sag ua rau kev tsim kho du. Ntawm cov khoom gypsum series, hydroxypropyl methylcellulose cellulose ether feem ntau ua lub luag haujlwm ntawm kev khaws dej thiab lubrication, thiab tib lub sijhawm muaj qee qhov cuam tshuam retarding, uas daws cov teeb meem ntawm lub nruas tawg thiab pib lub zog tsis ua haujlwm thaum lub sijhawm tsim kho. , tuaj yeem ntev lub sijhawm ua haujlwm. Hydroxypropyl methylcellulose interface tus neeg sawv cev feem ntau yog siv ua thickener, uas tuaj yeem txhim kho lub zog tensile thiab shear zog, txhim kho qhov txheej saum npoo, txhim kho kev sib txuas thiab lub zog sib txuas. Cov Khoom: Cov khoom no yog hmoov dawb lossis me ntsis daj, tsis muaj ntxhiab, tsis muaj saj thiab tsis muaj tshuaj lom. Kev khaws dej thiab ua kom muaj zog ntxiv. , hmoov putty lossis lwm yam khoom siv hauv tsev ua tus khi kom txhim kho kev sib kis thiab ua kom lub sijhawm ua haujlwm ntev. Nws tuaj yeem siv ua cov vuas nplaum, marble, kho kom zoo nkauj yas, txhawb nqa cov nplaum, thiab tseem tuaj yeem txo cov cement. Kev ua haujlwm khaws dej ntawm HPMC tiv thaiv cov slurry los ntawm kev tawg vim qhuav sai dhau tom qab thov, thiab txhim kho lub zog tom qab tawv. Kev tsim khoom siv ceramic: Nws yog dav siv ua tus khi hauv kev tsim cov khoom siv ceramic. PH ruaj khov: Lub viscosity ntawm cov kua dej ntawm cov khoom no yog qhov ruaj khov hauv qhov ntau ntawm PH3.0-11.0. Cov nyhuv khaws dej: Hydroxypropyl methylcellulose yog hydrophilic thiab nws cov kua dej yog viscous heev. Hydroxypropyl methylcellulose (HPMC) yog ntxiv rau mortar, gypsum, xim, thiab lwm yam kom tswj tau qhov khaws dej siab hauv cov khoom. Kev khaws cov duab: Piv nrog rau lwm cov polymers uas yaj hauv dej, cov kua dej ntawm cov khoom no muaj cov yam ntxwv tshwj xeeb viscoelastic. Nws qhov ntxiv tuaj yeem txhim kho lub peev xwm ntawm cov khoom siv ceramic extruded, thiab lwm yam.

Lubricity ntawm hydroxypropyl methylcellulose (HPMC): Ntxiv cov khoom no tuaj yeem txo qhov coefficient sib txhuam thiab txhim kho lubricity ntawm cov khoom siv ceramic extruded thiab cov khoom cement. Cov khoom tsim zaj duab xis: Cov khoom no tuaj yeem tsim cov ntawv muaj zog, yoog tau, thiab pob tshab nrog cov roj zoo thiab ester tsis kam, tshwj xeeb tshaj yog qhov khaws cia dej thiab kev tsim kho tshwj xeeb ntawm hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose Cov khoom tsim zaj duab xis ntawm cellulose tau nyob rau pem hauv ntej hauv Suav teb.
