Hydroxypropyl methylcellulose mu matope owuma a ufa, kuwonjezera kwa cellulose ether kumakhala kochepa kwambiri, koma kungathe kupititsa patsogolo ntchito ya matope onyowa, ndipo ndi chowonjezera chachikulu chomwe chimakhudza ntchito yomanga matope.
Hydroxypropyl methylcellulose Ether ya cellulose yomwe imagwiritsidwa ntchito mumatope owuma ndi makamaka hydroxypropyl methylcellulose ether (HPMC). Mu zisa zadothi zatsopano za uchi, zimatha kupereka mafuta kuzinthu zopanda kanthu. M'makampani okutira, angagwiritsidwe ntchito ngati thickener, dispersant ndi stabilizer mu makampani ❖ kuyanika, ndipo ali ngakhale zabwino mu madzi kapena zosungunulira organic. Monga chochotsera utoto. Kusindikiza kwa inki: Amagwiritsidwa ntchito ngati thickener, dispersant ndi stabilizer mu makampani inki, ndipo ali ngakhale bwino m'madzi kapena zosungunulira organic. .Pulasitiki: ntchito monga kupanga kumasulidwa wothandizila, softener, lubricant, etc. Polyvinyl kolorayidi: Amagwiritsidwa ntchito ngati dispersant kupanga polyvinyl kolorayidi, ndipo ndi waukulu wothandizira wothandizila pokonzekera PVC ndi kuyimitsidwa polymerization. Hydroxypropyl methylcellulose Zina: Izi zimagwiritsidwanso ntchito kwambiri pazikopa, mapepala, kusunga zipatso ndi masamba komanso mafakitale a nsalu.
HPMC mu matope owuma a ufa makamaka imagwira ntchito yosungira madzi, kulimbitsa ndi kupititsa patsogolo ntchito yomanga. Kusungidwa kwamadzi kwamatope omangira ndi mchenga wopaka pulasitala kumatha kutsitsa simenti mokwanira ndikuwonjezera mphamvu yomangira. Panthawi imodzimodziyo, imatha kuonjezera mphamvu zowonongeka ndi kumeta ubweya, kupititsa patsogolo ntchito yomanga ndikuwongolera bwino ntchito. Kusagonjetsedwa ndi madzi komanso mafuta Mu putty, hydroxypropyl methylcellulose cellulose ether makamaka imagwira ntchito yosungira madzi, kugwirizana ndi mafuta, kupewa ming'alu ndi kutaya madzi m'thupi chifukwa cha kutaya madzi ambiri, ndipo nthawi yomweyo kumapangitsanso kumamatira kwa putty ndi kuchepetsa kumanga. nthawi. Chochitika chapakati cha sag chimapangitsa kuti zomangamanga zikhale zosavuta. Pakati pa zinthu za gypsum series, hydroxypropyl methylcellulose cellulose ether makamaka imagwira ntchito yosungira madzi ndi kudzoza, ndipo nthawi yomweyo imakhala ndi zotsatira zochepetsera, zomwe zimathetsa mavuto a ng'oma ndi kulephera kwamphamvu koyamba panthawi yomanga. , akhoza kuwonjezera maola ogwira ntchito. Hydroxypropyl methylcellulose mawonekedwe agent amagwiritsidwa ntchito makamaka ngati thickener, amene angathe kupititsa patsogolo mphamvu kumakanika ndi kukameta ubweya mphamvu, kusintha ❖ kuyanika pamwamba, kumapangitsanso adhesion ndi kugwirizana mphamvu. Katundu: Izi ndi zoyera kapena zachikasu pang'ono ufa, zopanda fungo, zopanda pake komanso zopanda poizoni. Kusungirako madzi ndi kuwonjezeka mphamvu. , putty powder kapena zipangizo zina zomangira monga chomangira kuti ziwonjezeke kufalikira ndikutalikitsa nthawi yogwira ntchito. Itha kugwiritsidwa ntchito ngati matailosi a phala, marble, kukongoletsa pulasitiki, kulimbitsa phala, komanso kuchepetsa kuchuluka kwa simenti. Kusunga madzi kwa HPMC kumalepheretsa slurry kusweka chifukwa cha kuyanika mwachangu mukatha kugwiritsa ntchito, ndikuwonjezera mphamvu pambuyo poumitsa. Kupanga Ceramic: Amagwiritsidwa ntchito kwambiri ngati chomangira popanga zinthu za ceramic. Kukhazikika kwa PH: Kukhuthala kwa njira yamadzimadzi ya mankhwalawa ndi yokhazikika pamtundu wa PH3.0-11.0. Mphamvu yosungira madzi: Hydroxypropyl methylcellulose ndi hydrophilic ndipo yankho lake lamadzi ndi lowoneka bwino. Hydroxypropyl methylcellulose (HPMC) amawonjezedwa ku matope, gypsum, utoto, ndi zina zotero kuti asunge madzi ochuluka mu mankhwala. Kusungirako mawonekedwe: Poyerekeza ndi ma polima ena osungunuka m'madzi, yankho lamadzi la mankhwalawa lili ndi ma viscoelastic apadera. Kuphatikizika kwake kumatha kupititsa patsogolo luso losasinthika la zinthu zopangidwa ndi ceramic, etc.
Lubricity of hydroxypropyl methylcellulose (HPMC): Kuwonjezera mankhwalawa kungachepetse kugundana kwamphamvu ndikuwongolera mafuta azinthu zadothi ndi zinthu za simenti. Mafilimu opanga mafilimu: Mankhwalawa amatha kupanga mapepala amphamvu, osinthasintha, komanso owonekera bwino ndi mafuta abwino ndi ester kukana, makamaka kusunga madzi ndi kumanga kwapadera kwa hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose Katundu wopanga filimu wa cellulose patsogolo ku China.
