Kodi HPMC 100000 ndi chiyani?

HPMC 100000 ndi mtundu wa hydroxypropyl methylcellulose (HPMC) womwe umagwiritsidwa ntchito kwambiri pantchito yomanga ngati thickener, binder, and water retention agent munjira zosiyanasiyana monga matope opangidwa ndi simenti, zomatira matailosi, ndi zinthu za gypsum. Ndi non-ionic cellulose ether yomwe imapezeka mwa kusintha mankhwala a cellulose.

HPMC 100000 idapangidwa makamaka kuti igwiritsidwe ntchito mumatope opangidwa ndi simenti ndi zida zina za simenti. Amadziwika ndi zinthu zabwino kwambiri zosungira madzi, zomwe zimathandiza kuti zisamagwire ntchito komanso kusasinthasintha kwa zinthu za simenti kwa nthawi yaitali. Izi ndizofunikira makamaka m'malo otentha komanso owuma, pomwe zida za simenti zimatha kuuma mwachangu komanso zovuta kuzigwira.

Chimodzi mwazabwino zazikulu za HPMC 100000 ndikutha kuwongolera mphamvu zomatira zamatope opangidwa ndi simenti ndi zida zina za simenti. Izi zimatheka popanga filimu yozungulira tinthu tating'ono ta simenti, zomwe zimawonjezera kugwirizana kwawo ndi kumamatira ku gawo lapansi. Katunduyu amawonetsetsa kuti matope kapena zinthu zina za simenti zimakhalabe bwino ndipo sizimang'ambika kapena kupatukana ndi gawo lapansi.

Phindu lina lofunika la HPMC 100000 ndikutha kuchepetsa kuchuluka kwa madzi ofunikira mumatope opangidwa ndi simenti ndi zida zina za simenti. Pokonza kusungirako madzi, HPMC 100000 imalola kuti pakhale zolimba kwambiri mumatope, zomwe zingathandize kuchepetsa nthawi yowumitsa ndikuwongolera ntchito yonse ya zinthuzo.

HPMC 100000 imadziwikanso chifukwa cha mawonekedwe ake abwino kwambiri a rheological, omwe amathandizira kukonza magwiridwe antchito ndikugwiritsa ntchito matope opangidwa ndi simenti ndi zida zina za simenti. Zimagwira ntchito ngati thickener, zomwe zimapangitsa kuti zinthuzo zikhale zogwirizana komanso zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito gawo lapansi. Zimagwiranso ntchito ngati chomangira, chomwe chimathandizira kulimbitsa mphamvu ndi kulimba kwa zinthuzo.

Kuphatikiza pakugwiritsa ntchito matope opangira simenti ndi zida zina za simenti, HPMC 100000 imagwiritsidwanso ntchito pazinthu zina zosiyanasiyana pantchito yomanga. Mwachitsanzo, nthawi zambiri amagwiritsidwa ntchito ngati chomangira zinthu za gypsum, monga pulasitala ndi zomangira zomangira. Amagwiritsidwanso ntchito ngati thickener ndi chosungira madzi mu zomatira matailosi ndi grouts.

Mlingo wovomerezeka wa HPMC 100000 umasiyana malinga ndi momwe angagwiritsire ntchito komanso zomwe mukufuna pazinthu zopangira simenti. Nthawi zambiri, mlingo wa 0.2% mpaka 0.5% wa HPMC 100000 potengera kulemera kwa simenti ndi mchenga ukulimbikitsidwa pamatope opangidwa ndi simenti.

HPMC 100000 ndi chowonjezera chosinthika komanso chothandiza chomwe chitha kupititsa patsogolo magwiridwe antchito amatope opangidwa ndi simenti ndi zida zina za simenti. Makhalidwe ake osungira madzi, mphamvu zomatira, ma rheological properties, komanso kuthekera kochepetsera madzi ofunikira kumapangitsa kuti ikhale njira yokongola kwa makontrakitala, omanga nyumba, ndi eni nyumba omwe akuyang'ana kuti apititse patsogolo ntchito zawo zopangira simenti. Chiyambi chake, kukhazikika, komanso kuyanjana ndi chilengedwe kumapangitsanso kuti ikhale njira yabwino kwa iwo omwe amayika patsogolo njira zomanga zokhazikika.
