Uhlelo olujwayelekile lomphumela wokufaka isicelo we-HPMC lumi kanje:
Amandla okusebenza okusabela kulesi sinyathelo ancishisiwe, kuyilapho uketshezi lwengxube yokusabela kuthuthukiswa, futhi isici sesivuno esiphansi sokusabela kwe-methylation kwinqubo yokuqala siyaxazululwa. Esibonelweni, ngocwaningo nokusebenzisa i-reactor yesigaba esiqinile, izinhlayiya ze-hydroxypropyl methylcellulose phthalate ziyakhiwa.
Enye iwukuba umsizi osebenza kahle kakhulu, uthuthukise isivuno sokusabela, futhi ulawule ukukhiqizwa kokusabela okuseceleni,
Okwesibili, njenge-catalyst, i-HPMC isetshenziswa njenge-catalyst ephumelelayo yokuthuthukisa ukuhlanzeka kwama-reactants kanye nesivuno sokusabela, ukuze isivuno sokusabela sikhuphuke sibe ngu-98%. Izinga lokusetshenziswa kwezinto ezingavuthiwe likhuphukela ku-95% ngokusetshenziswa kwe-hydroxypropyl methyl cellulose njenge-ejenti eyisiza, eqinisekisa ukulungiswa kwe-hydroxypropyl methyl cellulose phthalate futhi ivimbele ukuhlangana phakathi kwezinhlayiya zenqubo yangemuva kokwelashwa.
Okwesithathu ukuxazulula inkinga yesivuno esincane senqubo yokuqala. Isilingo esimele ukwehlisa ukusetshenziswa kweyunithi ye-fiber kakotini eluhlaza isuka ku-1.05t/t yenqubo yokuqala iye ku-0.94t/t ngesikhathi sokusabela kwe-phthalic acid., Enqubweni yokusabela kwe-hydroxypropylation, izinsalela ze-phthalic anhydride reaction, i-phthalic acid yamahhala kanye i-acetic acid solvent esele ingasuswa. Isivuno salesi sinyathelo sikhuphuke safinyelela ku-95%.
I-Youngcel HPMC/MHEC isetshenziswa kabanzi njenge-Chemical Auxiliary Agent ye-Tile Adhesive, Cement Plaster, Dry mix mortar, Wall putty, Coating, Detergent nokunye.Futhi singakunikeza amanani aphansi kanye nekhwalithi engcono kakhulu.
Imikhiqizo yethu idumile eGibhithe, eRussia, eNingizimu Afrika, eMpumalanga Ephakathi, eTurkey, eVietnam, eFrance, e-Italy, eSingapore, eBangladesh, e-Indonesia, eNingizimu Melika njalonjalo. Siyabonga kusengaphambili futhi wamukelekile ukuthintana.
