Ana amfani da Hydroxypropyl methylcellulose azaman kayan albarkatun ƙasa don samar da mai, wanda zai iya fahimtar amfani da jimillar sukari, haɓaka ƙimar amfani da albarkatun ƙasa, rage ragowar adadin substrate a cikin broth fermentation, da rage farashin jiyya na ruwa. Wannan hydroxypropyl methylcellulose Babban halayen halayen yana dacewa da haɓakawa na tsari, ciyarwa-batch da ci gaba da tafiyar matakai na fermentation, guje wa jerin matsaloli irin su kula da matsakaicin abun da ke ciki da kuma dilution rate; Hakanan yana da amfani ga tsarin tsarin fermentation.
Hydroxypropyl methylcellulose, da albarkatun kasa cellulose, za a iya tace auduga ko itace ɓangaren litattafan almara. Yana da matukar muhimmanci a murkushe shi kafin alkalization ko lokacin alkalization. Murkushewa shine ya lalata albarkatun cellulose ta hanyar makamashin inji. A tara jihar tsarin na cellulose macromolecules iya rage mataki na crystallinity da polymerization, ƙara da surface area, game da shi inganta da damar da sinadaran dauki ikon reagent ga uku hydroxyl kungiyoyin a kan glucose zobe kungiyar na cellulose macromolecule.
Ko da yake da kira ka'idar etherification na hydroxypropyl methylcellulose ba rikitarwa, daban-daban muhallin alkalization, albarkatun kasa murkushe, etherification, sauran ƙarfi dawo da, centrifugal rabuwa, wanka da bushewa unsa babban adadin key fasahar da wadata ilmi connotations. Don nau'ikan samfura daban-daban, kowane yanayi yana da sabbin yanayin sarrafawa, kamar zazzabi, lokaci, matsa lamba da sarrafa kwararar kayan. Kayayyakin taimako da kayan sarrafawa sune garanti masu kyau don ingantaccen ingancin samfur da ingantaccen tsarin samarwa.
Tun da aikin hydroxypropyl methylcellulose yayi kama da sauran ethers mai narkewa na ruwa, ana iya amfani da shi azaman wakili na samar da fim, mai kauri, emulsifier da stabilizer a cikin fenti na latex da abubuwan fenti mai narkewa na ruwa.
Yi fim ɗin shafi yana da juriya mai kyau, daidaitawa da mannewa, da haɓaka tashin hankali na farfajiya, kwanciyar hankali ga acid da alkali, da dacewa da samfuran ƙarfe. Hydroxypropyl methylcellulose yana da sakamako mai kyau a matsayin mai kauri don fenti polyvinyl acetate na tushen ruwa. Matsayin maye gurbin ether cellulose yana ƙaruwa, kuma ana haɓaka juriya ga yashwar kwayan cuta.
