HPMC Hydroxypropyl methyl cellulose, tseem hu ua hydroxypropyl methyl cellulose ether (HPMC), cellulose hydroxypropyl methyl ether, yog xaiv cov paj rwb ntshiab heev cellulose li raw khoom, nyob rau hauv alkaline tej yam kev mob los ntawm tshwj xeeb etherification thiab npaj.
Hydroxypropyl methyl cellulose HPMC siv hauv kev tsim kho, cellulose ether ntxiv tus nqi qis heev, tab sis tuaj yeem txhim kho kev ua haujlwm ntawm cov khib nyiab ntub dej, mortar kev ua tau zoo yog qhov tseem ceeb ntxiv.Tam sim no, hydroxypropyl methyl cellulose siv nyob rau hauv qhuav mortar cellulose ether yog tsuas yog hydroxypropyl methyl cellulose ether (HPMC).Hydroxypropyl methyl cellulose nyob rau hauv kev tsim kho mortar qhuav HPMC feem ntau plays lub luag hauj lwm nyob rau hauv dej tuav, thickening, txhim kho kev tsim kho kev ua tau zoo.
1, kev tsim kho mortar plastering mortar
Kev tuav dej siab tuaj yeem ua rau cov cement tag nrho hydrated, ua kom muaj zog ntawm daim ntawv cog lus, thiab tuaj yeem txhim kho lub zog tensile thiab shear zog, zoo heev txhim kho kev tsim kho, txhim kho kev ua haujlwm.
2, dej-resistant putty
Nyob rau hauv lub putty HPMC hydroxypropyl methyl cellulose ether mas plays lub luag hauj lwm ntawm dej retention, bonding thiab lubrication, kom tsis txhob muaj qhov tshwm sim ntawm cov kab nrib pleb thiab lub cev qhuav dej tshwm sim los ntawm cov dej ceev heev, thiab txhim khu lub adhesion ntawm lub putty, txo cov phenomenon ntawm ntws dai nyob rau hauv lub putty. kev tsim kho, kom qhov kev tsim kho yog tus du.
3, xim gypsum series
Nyob rau hauv gypsum series ntawm cov khoom HPMC hydroxypropyl methyl cellulose ether tsuas yog ua si dej tuav, nce lubrication thiab lwm yam teebmeem, tib lub sij hawm muaj qee qhov kev ncua sijhawm, los daws cov txheej txheem kev tsim kho nruas tawg, pib lub zog tsis yog qhov teeb meem, tuaj yeem ua kom ntev. lub sijhawm ua haujlwm.
4, tus neeg saib xyuas interface
Feem ntau siv los ua cov thickener, nws tuaj yeem txhim kho lub zog tensile thiab shear zog, txhim kho txheej txheej, txhim kho adhesion thiab kev sib txuas lub zog.
5, Sab nraud rwb thaiv tsev mortar
HPMC Hydroxypropyl methyl cellulose, cellulose ether nyob rau hauv cov khoom tsom rau kev sib txuas, ua kom muaj zog, ua kom yooj yim rau cov tshuaj khib nyiab, txhim kho kev ua haujlwm, tib lub sij hawm yog ntau ntsug ntws tsis kam, kev ua haujlwm siab dej tuaj yeem ua rau lub sijhawm ua haujlwm ntawm mortar, txhim kho lub shrinkage thiab thermal qaug zog tsis kam, txhim kho nto zoo, txhim kho kev sib raug zoo zog.
6, ceramic pobzeb binder
Kev tuav dej siab tuaj yeem tsis tuaj yeem ntub dej los yog ntub cov nplais pobzeb thiab hauv paus, txhim kho nws txoj kev ruaj khov, slurry tuaj yeem siv sijhawm ntev, muag muag, zoo ib yam, kev tsim kho yooj yim, thiab muaj kev tiv thaiv zoo rau cov dej noo.
7, seam filling agent, sib koom tus neeg sawv cev
Qhov sib ntxiv ntawm hydroxypropyl methyl cellulose HPMC cellulose ether ua rau nws muaj cov ntug zoo adhesion, qis shrinkage thiab siab hnav tsis kam, tiv thaiv cov khoom siv los ntawm kev puas tsuaj, kom tsis txhob muaj kev cuam tshuam ntawm kev nkag mus rau tag nrho lub tsev.
8, self-leveling khoom
Hydroxypropyl methyl cellulose cellulose ether ruaj khov daim ntawv cog lus los xyuas kom meej zoo liquidity thiab self-leveling muaj peev xwm, tswj dej tuav tus nqi kom nws muaj peev xwm sai sai solidify, txo cracking thiab contraction.
9. Latex xim
Hydroxypropyl methyl cellulose nyob rau hauv txheej kev lag luam cellulose ether li zaj duab xis-yav tas los, thickening tus neeg saib xyuas, emulsifier thiab stabilizer siv, ua kom nws muaj zoo abrasion tsis kam, txheej, nplaum, txhim kho qhov zoo ntawm PH tus nqi ntawm qhov nro, thiab organic solvent sib tov nyhuv yog qhov zoo dua, Gao Baoshui kev ua tau zoo ua rau nws muaj kev txhuam zoo thiab ntws cov cuab yeej.
10. Honeycomb ceramics
Nyob rau hauv cov tshiab honeycomb ceramics, lub billet yog muab lubricity, dej tuav thiab lub zog li.
Cov khoom siv zoo heev hydroxypropyl methyl cellulose series tuaj yeem daws qhov teeb meem ntawm dej tuav hauv qhov kub thiab txias.Nyob rau hauv lub caij kub kub, tshwj xeeb tshaj yog nyob rau hauv kub thiab qhuav thiab nyias txheej tsim nyob rau hauv tshav ntuj sab, siab HPMC yog tsim nyog los txhim kho cov dej tuav ntawm slurry.High quality HPMC, uniformity yog zoo heev, nws methoxy thiab hydroxypropyl pawg raws cellulose molecular saw uniform tis, tuaj yeem txhim kho hydroxyl thiab ether daim ntawv cog lus ntawm oxygen atoms thiab dej koom haum hydrogen daim ntawv cog lus muaj peev xwm, ua dej dawb rau hauv dej ua ke, thiaj li ua tau zoo. tswj cov evaporation ntawm cov dej tshwm sim los ntawm huab cua kub, kom ua tiav cov dej khaws cia siab.
Cov khoom zoo ntawm hydroxypropyl methyl cellulose tuaj yeem sib npaug thiab ua haujlwm zoo hauv cov khoom siv cement mortar thiab plaster, thiab pob tag nrho cov khoom siv, thiab tsim ib txheej ntawm wetting zaj duab xis, cov dej noo nyob rau hauv lub hauv paus rau lub sij hawm ntev maj mam tso tawm, thiab inorganic cementitious khoom hydration tshuaj tiv thaiv. , yog li txhawm rau xyuas kom meej lub zog ntawm daim ntawv cog lus thiab compressive zog ntawm cov ntaub ntawv.Yog li ntawd, nyob rau lub caij ntuj sov kev tsim kho, kom ua tiav cov txiaj ntsig ntawm kev txuag dej, raws li cov qauv tsim los ntxiv cov khoom zoo HPMC, txwv tsis pub, yuav qhuav sai heev los ntawm dej tsis txaus, txo lub zog, tawg, hollow nruas thiab ntog tawm thiab lwm yam teeb meem zoo, tab sis kuj ua rau cov neeg ua haujlwm nyuaj tsim kho.Raws li qhov kub thiab txias qis, tus nqi ntawm HPMC tuaj yeem txo qis, thiab tib cov dej tuav tau tuaj yeem ua tiav.
