Mliriwu wa ViscCex of Hydroxypropyll methylcellulose ndilolo 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! Cholondola ndi cholondola!
1. Kuwongolera mafakisoni
Kukwera kwambiri hydroxpyll methylcellulose sikungathe kupanga cellulose yayitali kokha pongolowetsa. Nthawi zambiri, kupanga kwa cellulose ku China sikungayendetsedwe. Komabe, ngati mpweya wa oxygen umayikidwa mu ketulo, kupanga ma visccyo kumatha kulamuliridwa mwadala.
2. Gwiritsani Ntchito Ogwira Ntchito
Kuphatikiza apo, poganizira kuthamanga kwa nayitrogeni, ndikosavuta kupanga zinthu zam'magazi kwambiri ngakhale mutakhala kuti dongosolo. Zachidziwikire, kuchuluka kwa polymerization kwa thonje loyengekanso ndikofunikira. Ngati izi sizigwira ntchito, ndiye kuti muchite ndi mayanjano a hydrophobic. Pali othandizira omwe ali m'derali ku China. Ndi mtundu wanji wa othandizira kuti asankhe ali ndi mphamvu kwambiri pakuchita komaliza.
3. Hydroxypropyl
Oxygen otsalira mu riyakitala amayambitsa kuwonongeka kwa cellulose ndi kuchepa kwa kulemera kwake, koma mpweya wotsalira wolemera, bola mamolekyulu osweka amayanjana. Komabe, kuchuluka kwa kufalikira kumakhudzana kwambiri ndi zomwe zili hydroxypyl. Mafakitale ena amangofuna kuchepetsa mtengo ndi mtengo, koma osafuna kuwonjezera ma hydroxypropyl, ndiye kuti mtunduwo sungafike pamlingo wazinthu zakunja zofanana.
4.. Zina
Kusunga kwamadzi kwa malonda kumakhala ndi ubale wabwino ndi hydroxypyl, koma chifukwa cha chirichonse, chimasankhanso ndalama zake, kuchuluka kwa methyl chloride ndi ma programition. Kuchuluka kwa thonje loyengeka kumatsimikizira magwiridwe antchito.
