I-Celsulose Ether iyi-cellulose yemvelo (ukotini ocwengekile kanye ne-solip pulp, njll.) Njengezinto zokwakha eziluhlaza, ngemuva kokuthezeka kwezinhlobonhlobo zezinto zokutholwa, yi-cellulose macromolecule hydroxen nge-ether group ngokwengxenye, kuthathelwa indawo ye-cellulose. I-cellulose ingachithwa emanzini, i-dilite solution kanye ne-organic solvent ngemuva kokuthethelwa, futhi inezakhiwo ze-thermoplastic. Izinhlobonhlobo ze-cellulose erher, esetshenziswa kabanzi ekwakheni, usimende, ukuhlanganisa, umuthi, ukudla, uphethiloli, amakhemikhali nsuku zonke, izindwangu, amaphepha kanye nezimboni. Ngokuya ngenani lokufakwa esikhundleni kungahlukaniswa nge-ether eyodwa ne-ether exubile, ngokusho kwe-ionization kungahlukaniswa ku-ionic cellulose ether ne-nonic cellulose ether ne-nonic cellulose ether ne-ether. Njengamanje, ionic cellulose ether ionic Product Production Production Production Production Production Production ikhulile, kulula ukwenza futhi kuncishiswe izindleko eziphansi, izithiyo eziphansi zezimboni, ikakhulukazi izithasiselo zokudla, imikhakha yansuku zonke, yimikhiqizo ebalulekile yokukhiqiza emakethe.
Njengamanje, i-Maintream Cellulose ether yi-CMC, i-HPMC, i-MC, i-HPMC kanye nezinye izingxenye ze-HPMC kanye ne-HPMC kanye ne-Akhawunti ye-13% yemakethe yomhlaba wonke. Ukusetshenziswa okubaluleke kakhulu kwe-carboxymethyl cellulose (CMC) kungukuhlanza, ukubalwa kwemali cishe ngo-22% wesidingo semakethe esiphansi, neminye imikhiqizo isetshenziswa ikakhulukazi ezintweni zokwakha, ukudla nomuthi.
II. Isicelo se-Downstream
Esikhathini esedlule, ngenxa yokuthola ukuthuthukiswa okulinganiselwe kwe-cellulose ether ngamakhemikhali nsuku zonke, umuthi, ukudla, ukumboza kanye nemikhakha ye-cellulose ether eChina, kuze kube namuhla, imboni yezinto zokwakha isala ama-33% wesidingo se-cellulose ether eChina. Futhi njenge-ether ye-cellulose ether emkhakheni wezinto zokwakha izinto sekugcwele, kumakhemikhali nsuku zonke, umuthi, ukudla, ukunamathela kanye neminye imikhakha yokufunwa kukhula ngokushesha ngokuthuthuka kobuchwepheshe bohlelo lokusebenza. Isibonelo, eminyakeni yamuva nje, i-capsule yesitshalo nge-cellulose ether njengezinto eziphambili ezingavuthiwe, kanye nemikhiqizo evelayo eyenziwe ngenyama yokufakelwa nge-cellulose ether inezidingo ezibanzi ze-cellulose.
Emkhakheni wezinto zokwakha, ngokwesibonelo, i-cellulose ether ngokuqina, ukugcinwa kwamanzi, ukusheshiswa kancane nezinye izici zodaka ezixubile, kufaka phakathi ukuthuthukiswa kwezinga le-portule, i-tature, njll. Kwezimboni zokwakha zokwakha, izinga lokwakha inqubo yokwakha liyaqhubeka nokuthuthuka, futhi izidingo zemvelo zabathengi zezinto zokwakha ziya ngokuya ziphezulu futhi ziphezulu, ziholele ekufuneni kwe-nonic cellulose ether emkhakheni wezinto zokwakha. Ngesikhathi sesikhathi seminyaka engu-13 yezinsuku ezinhlanu, iChina yasheshisa ukulungiswa kwezindlu ezihlangene futhi yaqinisa ukwakhiwa kwengqalasizinda yasemadolobheni, futhi ithuthukise ukulungiswa kabusha kwezindlu ezindala zokuhlala kanye nokulungiswa kwezindlu ezingezona eziphelele. Engxenyeni yokuqala ka-2021, amamitha-skwele angama-755 14.15 esindaweni yokuhlala saqalwa, amaphesenti angama-5.,5. Indawo egcwalisiwe yezindlu ingamamitha-skwele angama-364.81 million, up 25.7%. I-reject yendawo egcwalisiwe ye-Real Estate izoshayela isidingo esifanele emkhakheni wezinto zokwakha izakhiwo ze-cellulose ether.
3. Iphethini yokuncintisana yemakethe
I-China iyizwe lokukhiqiza le-cellulose emhlabeni jikelele, esigabeni samanje sezinto zokwakha zasekhaya Ibanga le-cellulose ether linevel level, amanye amabhizinisi amakhulu e-Celli Ngaphezu kweI-Chemin ChemistryAmathani amancane ayizinkulungwane eziyishumi, izinkulungwane zamathani ama-nonic cellulose ether amabhizinisi amancane okukhiqiza, iningi lalawa mabhizinisi amancane akhiqiza izinto ezejwayelekile zokwakha imodeli ye-ether, futhi akukho mandla okukhiqiza ukudla okuphezulu nemikhiqizo.
Amacala amane, ezokungenisa kanye ne-cellulose ether kanye nokuthumela ngaphandle
Ngo-2020, ngenxa yobhubhane lwaphesheya kwezilwandle kwaholela ekunciphiseni kwamabhizinisi akwamanye amazwe, ukuthunyelwa kwamanye amazwe e-Clap Cellulose ether kwakhombisa ukuthambekela okusheshayo, ngo-2020 ukufeza ukuthekelisa kwamathanga e-cellulose ether 77,272. Yize ivolumu yokuthekelisa ye-ether ye-cellulose eChina ikhula ngokushesha, imikhiqizo yokuthumela imikhiqizo yokuthumela ikakhulukazi isuselwa ezintweni zokwakha i-cellulose ether, kanti ivolumu yokuthekelisa ye-ether yezokwelapha kanye ne-ether ye-cellulose incane kakhulu, futhi inani elingeziwe lemikhiqizo yokuthumela ngaphandle. Njengamanje, ivolumu yokuthekelisa ye-cellulose ether eChina inevolumu yokungenisa amahlandla amane, kepha ivolumu yokuthekelisa ingaphansi kwezikhathi ezimbili inani. Emkhakheni wemikhiqizo ephezulu kakhulu ye-Meduel Selformulase ether ether ethertose Ether Ether Ether Refressiption isendaweni enkulu yentuthuko.
