Kuwala kwa hydroxypropyll methylcellulose kumakhudzidwa kwambiri ndi mfundo zotsatirazi:
1. Ubwino wa zinthu zosaphika.
Chachiwiri, zotsatira za kukwaniritsidwa.
3. Konzani Chiwerengero
4. Gawo la zosungunulira
5. Mphamvu ya kulowerera
Zinthu zina zimakhala ngati mkaka ngati atasungunuka, ena ndi oyera oyera, ena ndi achikasu, ndipo zina zimakhala zomveka bwino komanso zowoneka bwino. Nthawi zina acetic acid amatha kukhudza kwambiri. Ndikofunika kugwiritsa ntchito acetic acid pambuyo pa kuchepa. Chiwopsezo chachikulu ndi ngati zomwe zichitike zimasunthidwa mokwanira komanso ngati chiwerengero cha makina chikakhazikika (zida zina zimakhala ndi chinyezi komanso zomwe zili zosakhazikika, monga zosungunulira zomwe zimagwiritsidwa ntchito kubwezeretsanso). M'malo mwake, pali zinthu zambiri zomwe zikukhudza. Ngati zida zili zokhazikika ndipo ogwiritsa ntchito amaphunzitsidwa bwino, kupanga zikhale zolimba. Kuwala kopepuka sikungapitirire mitundu ya ± 2%, ndipo kufanana kwa magwiridwe a magulu olowa m'malo ayenera kuwongolera bwino. M'malo mofanana, kuwala kopepuka kumakhala bwino.
Zinthu zomwe zikukhudza mafayilo a hydroxypropyl me cellulose
Kukwera kwambiri hydroxpyll methylcellulose sikungathe kupanga cellulose yayitali kokha pongolowetsa. Nthawi zambiri, kupanga kwa cellulose ku China sikungayendetsedwe. Komabe, ngati zida zoyezera za oxygen zoyezera zitha kukhazikitsidwa mu ketulo, kupanga ma viscnce kumatha kulamulidwa mwaluso.
zopangidwa. 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. 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. 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.
