1. Ukuncintisana phakathi kwamafemu akhona
Njenge-ether ye-cellulose engeyona eye-ionic, i-hydroxypropyl methylcellulose inokusebenza okungcono kune-ionic cellulose ether ngokuya ngokuqina, ukufakwa kwamafilimu, ukwakheka komswakama, ukugcinwa komswakama, ukugcinwa komswakama. , Esetshenziswa kabanzi ekuxhashazweni kwensimu yamafutha, ukupenda kwe-latex, i-polymer polymerization, izinto zokwakha, amakhemikhali nsuku, ukudla, ukuphrinta okwenziwe ngemithi kanye neminye imikhakha yezimboni. Ngokusheshisa kokufuduka kwabantu emadolobheni, isidingo semikhiqizo nakanjani sizonyuka unyaka nonyaka. Kunezindawo ezinkulu zasemakhaya eChina, futhi imikhiqizo engezansi izokhulisa nokukhula. Thuthukisa ikhwalithi yomkhiqizo ukumelana nomncintiswano onolaka emakethe. Isidingo sizonyuka, kepha ngenxa yezidingo zokusebenza kwezindleko kanye nezindleko zemikhiqizo ye-HPMC nazo zizoba ngaphezulu. Ngokuzayo, ikhwalithi yomkhiqizo kanye nomkhiqizo kuzoba ukugxila kokuncintisana. Ukwephula izithiyo zezobuchwepheshe kanye nokuqinisekisa ukuqina komkhiqizo kuzoba yisihluthulelo ekuthuthukisweni okuzinzile kwemakethe yesikhathi esizayo.
2. Ukuhlaziywa okungaba khona
Ukusetshenziswa kwe-cellulose izithathekisa izinkambu eziningi zokusebenzisa ubuningi ezifana nezikhutha, ukumboza, imikhiqizo yokwakha kanye nama-outents e-Oyili Ama-Agents abhalwe ngaphezulu kwe-50% yawo wonke ama-cellulose ether ether. Ukusetshenziswa kwe-cellulose ether kuphendula ingxenye encane yokusetshenziswa okubonakalayo okubonakalayo kule mikhakha. Ngakho-ke, la mabhizinisi esibulalayo awananhloso yokukhiqiza i-cellulose ether kepha uyithenga emakethe.
3. Ukuhlaziywa kokuhlinzekwa kwezinto ezibonakalayo
Ukukhiqizwa kwe-HPMC yasekhaya ngokuvamile kusetshenziswa ukotini ocwengekile njengezinto ezingavuthiwe (abanye abakhiqizi baphinde baqalile ukuzama ukusebenzisa i-alkalization pulp), futhi basebenzise ngokuqondile ukotini ukuze baphendule, futhi basebenzise ukuncintisana emakethe, okuqinisa ukuncintisana embonini.
4. Funa ukuhlaziywa kwezinto
I-HPMC isetshenzisiwe emkhakheni wezinto zokwakha zangaphandle zamashumi eminyaka, futhi akukho mkhiqizo otholile ophelele. Kunesidingo esikhulu emakethe yamazwe omhlaba, kepha ngenxa yekhono lokukhiqiza nezinzuzo eziphelele zezinkampani zakwamanye amazwe, abakhiqizi abaningi bakwamanye amazwe, ikakhulukazi abakhiqizi baseYurophu nabaseMelika, basasebenza ikakhulukazi imikhiqizo yezinkampani zakwamanye amazwe. Eminyakeni yamuva, i-HPMC yasekhaya inezinzuzo ezisobala ekusebenzeni kwezindleko. Ngokukhuphuka kocwaningo lwesicelo, ukwakhiwa kwamazinga ezimboni zikazwelonke, kanye nokwenza ngcono okuqhubekayo kwekhwalithi yomkhiqizo, cishe kungashintsha ngokuphelele okungeniswayo futhi kusetshenziswa kabanzi emkhakheni wezinto zokwakha ezifuywayo. Ngakho-ke, kuyadingeka ukwenza umsebenzi omuhle ocwaningweni lokuguqulwa kanye nokuxhasa ubuchwepheshe ucwaningo lwe-HPMC ngokuzayo, futhi uhlakulele izinzuzo eziqondisayo eziqonde ngqo ukuze uhambisane nezidingo zokuthuthukiswa kwemakethe ekhaya nakwamanye amazwe.
5. Ukuhlaziywa Kwemininingwane Yokukhiqiza
Ukukhiqizwa kwe-HPMC kanye nenqubekela phambili yezobuchwepheshe akupheli, futhi izidingo zekhwalithi yomkhiqizo nazo zithuthukisa njalo, futhi ezinye abakhiqizi ziye zanda, futhi, kwabakhiqizi abasuselwa ku-HPMC, ezinye izimpikiswano ze-cellulose nazo ziyangezwa. Ukuhlangabezana nezidingo zezentengiso zemakethe kanye nenqubo yokufaka isicelo, kunamabhizinisi amaningi anjengalawase, anjengeShandong Rui Tai, Ukwanda kwezobuchwepheshe kanye nezinqubo ze-shunong, kukhuphuke kakhulu ukukhiqizwa kwenqubekela phambili yezobuchwepheshe ye amabhizinisi.
