Game da matsalar gel zafin jiki na hydroxypropyl methylcellulose HPMC, da yawa masu amfani da wuya kula da matsalar da gel zafin jiki na hydroxypropyl methylcellulose. A zamanin yau, ana bambanta hydroxypropyl methylcellulose gabaɗaya bisa ga danko, amma ga wasu yanayi na musamman da masana'antu na musamman, bai isa kawai nuna dankon samfurin ba. Mai zuwa a taƙaice yana gabatar da zafin gel na hydroxypropyl methylcellulose.
Adadin ƙungiyar methoxyl yana da alaƙa kai tsaye zuwa matakin haɓakar cellulose, kuma ana iya daidaita abun ciki na ƙungiyar methoxyl ta hanyar sarrafa dabarar, zafin jiki da lokacin amsawa. A lokaci guda, matakin rashin kunnawa yana rinjayar matakin maye gurbin hydroxyethyl ko hydroxypropyl. Sabili da haka, riƙewar ruwa na ether cellulose tare da babban zafin jiki na gel zai zama mara kyau. Wannan tsari na samarwa yana buƙatar bincika, don haka ba cewa farashin samar da ether na cellulose ya ragu ba idan abun ciki na methoxy ya ragu, akasin haka, farashin zai kasance mafi girma.
Zazzabi na gel an ƙaddara ta ƙungiyoyin metoxyl, kuma an ƙaddara riƙewar ruwa ta ƙungiyoyin hydroxypropoxyl. Akwai ƙungiyoyi masu musanya guda uku kawai akan cellulose. Nemo yanayin zafin amfani da ya dace, dacewar ruwa mai dacewa, sannan ƙayyade ƙirar wannan cellulose.
Yawan zafin jiki na gel yana da mahimmanci ga aikace-aikacen ether cellulose. Lokacin da yanayin yanayi ya wuce zafin gel, za a raba ether cellulose daga ruwa kuma ya rasa riƙewar ruwa. Gel zafin jiki na cellulose ether a kasuwa na iya cika buƙatun yanayin amfani da turmi (sai dai yanayi na musamman). Lokacin yin amfani da turmi, babu buƙatar kulawa ta musamman ga ma'aunin aikin zafin jiki na gel.
