Hydroxypropyl methyl cellulose i roto i te paru maroke, he iti rawa te taapiri o te cellulose ether, engari ka tino pai ake te mahinga o te paru paru, ko te mahinga hanga paru tetahi o nga mahi matua. Na, ko te hydroxypropyl methyl cellulose i whakamahia i roto i te maroke Cellulose Cellulose Ether Ko te nuinga o te hydroxypropyl methyl cellulose ether (HPMC). HydroxyPropyl cellulose i roto i te HPMC maroke HPMC e mahi ana i te pupuri wai, te matotoru, te whakapai ake i te mahinga o te hanga. Ko te hydroxypropyl methylcellulose HPMC kaore e uru atu ki tetahi tauhohenga matū, ko te mahi takoha noa. Ko te paura o te paura he wai, he tauhohenga matū, no te mea ko te whakatipuranga o nga mea hou, na te mea kua oti te hanga, na te mea kua hangahia he rauemi hou (te konupora hou). Ko nga waahanga matua o te paura hina hina: 2, COO + H2O = COA (OH) 2 tauhohenga.
Ko te kounga nui o te hydroxypropyl cellulose ka taea te whakamahi i nga waahanga raima me nga papaa raima katoa, me te whakakaha i te kaha o te wai. Na reira, i te hanganga raumati tiketike, kia tutuki ai nga hua o te HPMC kounga, kia tere ai te ngoikore, ka pakaru te kaha o nga kaimahi. I te heke o te pāmahana, ko te nui o te wai i tapiritia e te HPMC ka taea te whakaheke, a ka taea te whakatutuki i te mana pupuri wai.
