Mlirimo wahydroxypypyl methylcellulosendilolo lofunikira kwambiri. Mavinyeyo samayimira chiyero. Mafayilo a celluluse HPMC amatengera kupanga. Malo Osiyanasiyana a Agwiritsidwe Ntchito Ayenera kusankha Cellulose HPMC yokhala ndi ma viscosies osiyanasiyana, osati mafayilo apamwamba a cellulose HPMC, yabwinoko! Chabwino ndi cholondola √
Kuwongolera ma viru
1. Makutu-a Viscrence Hydroxpyll satha kupanga cellulose yayitali kokha mwakutuwa ndikusintha ndi nayitrogeni. Nthawi zambiri, kupanga kwa cellulose ku China sikungayendetsedwe. Komabe, ngati chida chofufumitsa cha oxygen chitha kukhazikitsidwa mu ketulo, kupanga matima kumatha kulamulidwa mwaluso.
Kugwiritsa ntchito othandizira
2. Kuphatikiza apo, poganizira kuthamanga kwa nayitrogeni, ndipo nthawi yomweyo, ndikosavuta kupanga zinthu zam'magazi kwambiri ngakhale mutakhala kuti dongosolo. Inde, kuchuluka kwa polymerization kwa thonje loyengekanso ndikofunikira. Ngati izi sizigwira ntchito, chitani ndi mayanjano a hydrophobic. Pali othandizira apabanja pankhaniyi. Ndi mtundu wanji wazomwe amasankhidwa ali ndi chiwopsezo chachikulu pakuchita komaliza.
Hydroxypyl
3. Okongoletsedwa otsalira mu riyakitala amayambitsa kuwonongeka kwa cellulose ndi kuchepetsa kwa maselo, koma otsalira otsalira ndi ochepa. Sikovuta kusintha kwambiri ma mamolekyulu osweka amayanjanitsidwanso. Komabe, kuchuluka kwa madzi kumagwirizananso kwambiri ndi zomwe zili hydroxypyl. Mafakitale ena amangofuna kuchepetsa mtengo ndi mtengo, ndipo sakufuna kuwonjezera ma hydroxypropyl, ndiye kuti mtunduwo sungafike pamlingo wofanana ndi zinthu zakunja.
Zina
4. Kusunga kwamadzi kwa malonda kumakhala ndi ubale wabwino ndi hydroxypyl, koma pazomwe zimachita, zimasankhanso kuchuluka kwa madzi, chiwerengero cha alkalide chloride ndi proprali . Ndipo kuchuluka kwa madzi ku thonje loyengeka kumatsimikizira magwiridwe antchito.
