Hydroxypropyl methylcellulose nyob rau hauv qhuav hmoov mortar, qhov sib ntxiv ntawm cellulose ether yog tsawg heev, tab sis nws muaj peev xwm ho txhim kho kev ua hauj lwm ntawm ntub mortar, thiab nws yog ib tug tseem ceeb additive uas cuam tshuam rau kev tsim kho ntawm mortar.
Hydroxypropyl methylcellulose Lub cellulose ether siv hauv cov hmoov qhuav mortar yog hydroxypropyl methylcellulose ether (HPMC). Hauv cov honeycomb ceramics tshiab, nws tuaj yeem muab lubricity rau qhov khoob. Hauv kev lag luam txheej, nws tuaj yeem siv los ua cov thickener, dispersant thiab stabilizer hauv kev lag luam txheej, thiab muaj kev sib raug zoo hauv dej lossis cov kuab tshuaj organic. Raws li cov xim tshem tawm. Ink printing: Nws yog siv los ua cov thickener, dispersant thiab stabilizer hauv kev lag luam number case, thiab muaj kev sib raug zoo hauv dej lossis cov kuab tshuaj organic. .Plastic: siv los ua tus neeg sawv cev tso tawm, softener, lubricant, thiab lwm yam Polyvinyl chloride: Nws yog siv los ua ib qho dispersant nyob rau hauv zus tau tej cov polyvinyl chloride, thiab yog lub ntsiab auxiliary tus neeg saib xyuas rau kev npaj PVC los ntawm ncua kev kawm ntawv polymerization. Hydroxypropyl methylcellulose Lwm tus: Cov khoom no kuj tau siv dav hauv cov tawv nqaij, cov khoom siv ntawv, cov txiv hmab txiv ntoo thiab zaub khaws cia thiab kev lag luam textile.
HPMC nyob rau hauv qhuav hmoov mortar mas plays lub luag hauj lwm ntawm dej tuav, thickening thiab txhim kho kev tsim kho kev ua tau zoo. Kev tuav dej siab ntawm kev tsim kho mortar thiab plastering xuab zeb tuaj yeem ua kom cov cement tag nrho thiab ua kom muaj zog ntxiv. Nyob rau tib lub sijhawm, nws tuaj yeem tsim nyog nce lub zog tensile thiab shear lub zog, zoo heev txhim kho kev tsim kho thiab txhim kho kev ua haujlwm. Dej-resistant thiab greasy Nyob rau hauv lub putty, hydroxypropyl methylcellulose cellulose ether mas plays lub luag hauj lwm ntawm dej tuav, bonding thiab lubrication, tsis txhob tawg thiab lub cev qhuav dej tshwm sim los ntawm cov dej ntau dhau, thiab nyob rau tib lub sij hawm txhim khu lub adhesion ntawm putty thiab txo cov kev tsim kho. sij hawm. Qhov nruab nrab sag phenomenon ua rau kev tsim kho smoother. Ntawm cov khoom lag luam gypsum, hydroxypropyl methylcellulose cellulose ether tsuas yog ua lub luag haujlwm ntawm cov dej tuav thiab lubrication, thiab tib lub sijhawm muaj qee yam kev cuam tshuam, uas daws cov teeb meem ntawm lub nruas tawg thiab pib lub zog tsis ua haujlwm thaum tsim kho. , tuaj yeem ncua sijhawm ua haujlwm. Hydroxypropyl methylcellulose interface tus neeg sawv cev yog siv los ua cov thickener, uas tuaj yeem txhim kho lub zog tensile thiab shear lub zog, txhim kho txheej txheej, txhim kho adhesion thiab kev sib txuas lub zog. Cov Khoom Siv: Cov khoom no yog cov hmoov dawb los yog daj me ntsis, tsis muaj ntxhiab, tsis qab thiab tsis muaj tshuaj lom. Kev tuav dej thiab muaj zog ntxiv. , putty hmoov los yog lwm yam khoom siv hauv tsev ua cov ntaub ntawv txhawm rau txhim kho kev sib kis thiab ua kom lub sijhawm ua haujlwm ntev. Nws tuaj yeem siv los ua cov nplais pobzeb, marble, kho kom zoo nkauj yas, muab tshuaj ntxiv, thiab tuaj yeem txo cov cement. Cov dej-tswj kev ua tau zoo ntawm HPMC tiv thaiv cov slurry los ntawm kev tawg vim ziab sai heev tom qab thov, thiab txhim kho lub zog tom qab hardening. Ceramic manufacturing: Nws yog siv dav hauv kev tsim cov khoom siv ceramic. PH stability: Lub viscosity ntawm cov kua aqueous ntawm cov khoom no yog qhov ruaj khov ntawm PH3.0-11.0. Cov nyhuv tuav dej: Hydroxypropyl methylcellulose yog hydrophilic thiab nws cov kua dej muaj kuab heev. Hydroxypropyl methylcellulose (HPMC) yog ntxiv rau mortar, gypsum, pleev xim, thiab lwm yam kom tswj tau cov dej siab hauv cov khoom. Kev tuav pov hwm zoo: Piv nrog rau lwm cov dej-soluble polymers, cov tshuaj aqueous ntawm cov khoom no muaj cov khoom tshwj xeeb viscoelastic. Nws qhov sib ntxiv tuaj yeem txhim kho lub peev xwm ntawm cov khoom siv extruded ceramic, thiab lwm yam.
Lubricity ntawm hydroxypropyl methylcellulose (HPMC): Ntxiv cov khoom no tuaj yeem txo cov kev sib txhuam coefficient thiab txhim kho lubricity ntawm extruded ceramic khoom thiab cov khoom cement. Zaj duab xis-tsim cov khoom: Cov khoom no tuaj yeem tsim cov nplooj ntawv muaj zog, hloov tau, thiab pob tshab nrog cov roj zoo thiab ester tsis kam, tshwj xeeb tshaj yog cov dej tuav thiab kev tsim tshwj xeeb ntawm hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose Cov cuab yeej ua yeeb yaj kiab ntawm cellulose tau nyob hauv pem hauv ntej hauv Suav teb.
