Ma cellulose apamwamba kwambiri a HPMC amatha kumwazikana moyenera komanso moyenera mumatope a simenti ndi zinthu za gypsum matrix.

Cellulose HPMC, yomwe imadziwikanso kuti hydroxypropyl methylcellulose, ndi chinthu chongowonjezedwanso komanso choteteza chilengedwe chochokera ku cellulose ku zamkati zamatabwa kapena ulusi wa thonje. Ndi polymer ya nonionic yokhala ndi bwino kusunga madzi, kukhuthala, komanso kupanga mafilimu. Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga zomangamanga, zamankhwala, chakudya, zodzoladzola, ndi nsalu.

M'makampani omangamanga, HPMC imagwiritsidwa ntchito makamaka ngati rheology modifier ndi madzi osungira madzi muzinthu za simenti monga matope, ma grouts, zomatira matailosi ndi mankhwala odzipangira okha. Zimagwira ntchito yofunikira pakuwongolera kusinthika, kulimba komanso magwiridwe antchito azinthu izi, kuwonetsetsa kuti zotsatira zake zizikhala zogwirizana komanso zodziwikiratu.

Chimodzi mwazabwino kwambiri za cellulose HPMC yapamwamba kwambiri ndikutha kwake kukhala wogawana komanso omwazika bwino mumatope a simenti ndi zinthu za gypsum matrix. Izi ndichifukwa cha kapangidwe kake kake kapadera ka mankhwala, kamene kamapangitsa kuti azigwirizana ndi zinthu zokhala ndi mchere izi ndipo amalola kupanga zokhazikika, zobalalika zofananira.

Mukawonjezeredwa kumatope a simenti kapena matrix a gypsum, HPMC imapanga chitetezo chozungulira tinthu ting'onoting'ono, kuti zisawonongeke kapena kukhazikika. Izi zimapangitsa kuti pakhale kusakaniza kofanana, kosavuta kugwiritsira ntchito, kuchepetsa chiopsezo cha kupatukana ndi kupititsa patsogolo kugwirizana ndi khalidwe la mankhwala omaliza.

Kuphatikiza apo, zinthu zosungira madzi za HPMC zimathandiza kuti zisunge chinyezi mkati mwa matrix, kupititsa patsogolo kuyatsa koyenera kwa tinthu ta simenti ndikuwonjezera mphamvu ya mgwirizano ndi kukhazikika pakati pawo. Izi ndizofunikira makamaka m'malo ovuta kwambiri omwe zinthu zimatha kukhala zowundana ndi kuzizira kapena chinyezi chambiri, zomwe zimapangitsa kuti ming'alu ing'ambe, kuphulika kapena kuphulika.

Kuphatikiza pa mapindu ake a rheological ndi kusunga madzi, HPMC imagwira ntchito ngati yokhuthala komanso yomangira zinthu zopangidwa ndi simenti, zomwe zimapereka kukhazikika komanso kumamatira. Imawongolera kukana kwa zomatira zamatailosi, imalepheretsa kukhetsa magazi kwazinthu zodzipangira okha komanso kumawonjezera kulimba kwa pulasitala kapena pulasitala.

HPMC ndi zinthu zopanda poizoni komanso zosawonongeka, zomwe zimapangitsa kuti zikhale zoyenera pamamangidwe okhazikika. Palibe ma VOC kapena zowononga zowononga zomwe zimatulutsidwa panthawi yopanga kapena kugwiritsidwa ntchito, ndipo zitha kutayidwa mosamala mukadzagwiritsidwa ntchito.

Ma cellulose apamwamba kwambiri a HPMC ndi chinthu chosunthika komanso chofunikira pantchito yomanga, kupititsa patsogolo magwiridwe antchito ndi kudalirika kwa zinthu zopangidwa ndi simenti. Kuthekera kwake kumwazikana molingana ndi bwino mkati mwa matope ndi pulasitala matrices, kuphatikiza ndi kusunga madzi, makulidwe ndi kumanga katundu, kumapangitsa kukhala chinthu chofunikira pantchito iliyonse yomanga.

Kukhazikika kwake komanso kuyanjana kwachilengedwe kumapangitsa kukhala chisankho choyenera kwa omanga ndi opanga omwe amaika patsogolo chitetezo cha chilengedwe ndi udindo wa anthu. Chifukwa chake, ndi zinthu zomwe ziyenera kuzindikirika ndikugwiritsidwa ntchito popititsa patsogolo ntchito yomanga komanso dziko lonse lapansi.
