Tlholisano ea indasteri ea cellulose ether

Ka tlhokahalo e ntseng e eketseha ea boleng bo phahameng ba cellulose ether meriana, lijo, lik'hemik'hale tsa letsatsi le letsatsi le liindasteri tse ling, tlhokahalo ea malapeng ea tse ling.cellulose etherlihlahisoa tse ling ntle le CMC lia hola, MC/HPMCmatla a ka bang lithane tse 120,000, matla a HEC a ka bang lithane tse 20,000. Tlhokahalo ea 'maraka oa cellulose ether e tsitsitse,' me e tsoela pele ho nts'etsapele le ho sebetsa masimong a macha, bokamoso bo tla bonts'a foromo ea kholo e ts'oanang. Tlhahlobo e latelang ea tlholisano ea indasteri ea cellulose ether.

China ke kholo ka ho fetisisa lefatšeng selulose tlhahiso ea ether le moreki, empa mahloriso a tlhahiso ea malapeng ha e phahame, matla a likhoebo a fapane haholo, phapang ea kopo ea sehlahisoa e totobetse, likhoebo tsa lihlahisoa tse phahameng li lebeletsoe ho hlahella. Litlhahlobo tsa indasteri ea cellulose ether li bontšitse hore ka selemo sa 2018, matla a mmaraka a China a selulose ether a lithane tse 510,000, 2025 e lebelletsoe ho fihla ho lithane tse 650,000, 2019 ho isa ho 2025 kholo ea selemo le selemo ea 3%.

Tlholisano ea indasteri ea cellulose ether

Ka lebaka la khaello ea matla a lichelete, likhoebo tse ngata tse nyenyane e le ho fokotsa litšenyehelo tsa tlhahiso, ts'ireletso ea tikoloho letsete la ho hloekisa metsi le phekolo ea khase ea ho ntša metsi ha e finyelle maemo. Ha naha le sechaba sohle se ntse se ela hloko haholo ts'ireletso ea tikoloho, likhoebo tse indastering tse sa khoneng ho fihlela litlhoko tsa ts'ireletso ea tikoloho li tla koala butle kapa li fokotse tlhahiso. Khatello ea indasteri ea tlhahiso ea cellulose ether ea China e tla ntlafatsoa le ho feta. Hona joale ho tloha likarolong tse peli ho hlahloba tlhōlisano ea indasteri ea cellulose ether.

Pharmaceutical grade cellulose ether ho HPMC e le mohlala, ke mofuta oa metsi a insoluble selulose e tsoakiloeng ether habeli ester, ka masala a tsoekere ka joala hydroxyl kapa hydroxypropyl hydroxyl e amana le methoxy, acetyl, butanediyl sehlopha lihlopha tse tharo. Tlhahlobo ea tlholisano ea indasteri ea cellulose ether, baetsi ba li-cellulose ether tse kholo linaheng tse tsoetseng pele haholo-holo ba nka "bakeng sa bareki ba phahameng ba boemo bo phahameng + nts'etsopele ea tšebeliso e tlase ea noka le ts'ebeliso" ea leano la tlholisano, ba fane ka papali e felletseng ho melemo ea bona ea boemo bo phahameng ba lipatlisiso le thekenoloji ea nts'etsopele, nts'etsapele ts'ebeliso le ts'ebeliso ea foromo ea lihlahisoa tsa cellulose ether. Ho ea ka karohano e fapaneng ea ts'ebeliso ea ho hlophisoa ha letoto la lihlahisoa, tse loketseng bareki ho li sebelisa, ho lema tlhoko ea 'maraka e tlase, le ho etella pele nts'etsopele ea theknoloji ea kopo ea cellulose ether.

Matla a likhoebo tsa tlhahiso ea cellulose ether Chaena ha a lekane, theknoloji ea kopo ea sehlahisoa ka kakaretso e fokola, mme lihlahisoa tsa likhoebo tse ngata li tlholisanong e tšoanang. Tlhahlobo ea tlholisano ea indasteri ea cellulose ether, bakeng sa baetsi ba China ba matla, ba kholoanyane, taolong ea boleng le taolo ea litšenyehelo e na le melemo e itseng, botsitso ba boleng ba sehlahisoa bo molemo, bo na le litšenyehelo tse ngata, limmarakeng tsa lehae le kantle ho naha li na le tlholisano e itseng. Lihlahisoa tsa likhoebo tsena li tsepamisitsoe haholo sehlopheng sa thepa ea moaho ea maemo a holimo selulose ether, sehlopha sa meriana, boemo ba lijo cellulose ether, kapa tlhoko ea 'maraka ke lisebelisoa tse kholo tse tloaelehileng tsa moaho tsa selulose ether. Ka lebaka la khaello ea bokhoni ba nts'etsopele ea theknoloji ea kopo, likhoebo tsa malapeng tse nang le matla a tšoanang li na le boemo ba tlhōlisano ea homogeneity ea lihlahisoa.

Tlhahlobo ea tlholisano ea indasteri ea cellulose ether, likhoebo tsa China tsa cellulose ether ha lia baka tlhokomelo, papatso e ntse e foufetse, esita le tse 'maloa tse tloaelehileng tsa cellulose ether li tloaelehile, mosebelisi le ho haella ha ak'haonte ea tekheniki, mosebelisi ha a ntse a sebelisa mathata a itseng a ke ke a rarolloa. mokhoa o nakong, ke se ke sa bue ka ho tataisa bareki, Ke tšepa hore lik'holejeng le liunivesithing tse ngata, litsi tsa lipatlisiso tsa ho kenya letsoho lipatlisisong tse tebileng tsa cellulose ether, lefats'e ka bophara.
