1. Izici ezivumayo
(1) Ukwesekwa kwenqubomgomo
Njengento entsha esekwe ku-bio kanye nezinto eziluhlaza futhi ezinobungani bemvelo, ukusetshenziswa okubanzi kwei-cellulose etheremkhakheni wezimboni umkhuba wokuthuthukiswa wokwakha umphakathi ovumelana nemvelo nowonga izinsiza esikhathini esizayo. Ukuthuthukiswa kwemboni kuhambisana nenhloso enkulu yezwe lami yokuzuza intuthuko yomnotho esimeme. Uhulumeni waseShayina ukhiphe ngokulandelana izinqubomgomo nezinyathelo ezifana “noHlelo Lukazwelonke Lwesikhathi Esimaphakathi Nesikhathi Eside Lokuthuthukiswa Kwesayensi Nobuchwepheshe (2006-2020)” kanye “noHlelo Lokuthuthukiswa Kwemboni Yokwakha “Uhlelo Lweminyaka Eyishumi Nambili Lweminyaka Emihlanu” ukuze kusekelwe imboni ye-cellulose ether.
Ngokusho kwe- "2014-2019 China Pharmaceutical Food Grade Cellulose Ether Market Monitoring and Investment Prospect Analysis Report" ekhishwe yi-China Industry Information Network, izwe liphinde lenze amazinga aqinile okuvikela imvelo, okuphakamise ukugcizelela ezindabeni zokuvikela imvelo entsha. izinga. Izijeziso ezinkulu zokungcoliswa kwemvelo zidlale indima enhle ekuxazululeni izinkinga ezifana nokuncintisana okungahlelekile embonini ye-cellulose ether kanye nokuhlanganisa amandla okukhiqiza embonini.
(2) Ithemba lokufakwa kwezicelo ezansi nomfula libanzi futhi isidingo siyanda
I-Cellulose ether yaziwa ngokuthi “i-industrial monosodium glutamate” futhi ingasetshenziswa emikhakheni eyahlukene yomnotho wezwe. Ukuthuthukiswa komnotho nakanjani kuzogqugquzela ukukhula kwemboni ye-cellulose ether. Ngokuthuthuka okuqhubekayo kwenqubo yezwe lami lokuthuthela emadolobheni kanye nokutshalwa kwezimali okuqinile kukahulumeni ezimpahleni ezingashintshi kanye nezindlu ezithengekayo, imboni yezokwakha kanye nezinto zokwakha izokwandisa kakhulu isidingo se-cellulose ether. Emkhakheni wezokwelapha nokudla, ukuqwashisa kwabantu ngempilo nokuvikelwa kwemvelo kuya ngokuya kukhula. Imikhiqizo ye-cellulose ether engenabungozi ngokomzimba futhi engangcolisi njenge-HPMC kancane kancane izothatha indawo yezinye izinto ezikhona futhi ithuthuke ngokushesha. Ngaphezu kwalokho, ukusetshenziswa kwe-cellulose ether ekugqokeni, i-ceramics, izimonyo, isikhumba, iphepha, irabha, amakhemikhali nsuku zonke nezinye izimboni ziya ngokuya ziba ziningi.
(3) Inqubekelaphambili yezobuchwepheshe iqhuba ukuthuthukiswa kwemboni
Esigabeni sokuqala sokuthuthukiswa kwemboni yezwe lami ye-cellulose ether, i-ionic carboxymethyl cellulose ether (CMC) yayingumkhiqizo oyinhloko. Ngokwenziwa kwe-ionic cellulose ether emelwe i-PAC kanye ne-non-ionic cellulose ether emelwe i-HPMC Ngokuthuthuka nokuvuthwa kwenqubo, inkambu yokusetshenziswa kwe-cellulose ether iye yandiswa. Ubuchwepheshe obusha nemikhiqizo emisha kuzoshesha esikhundleni semikhiqizo ye-cellulose ether yendabuko esikhathini esidlule futhi kukhuthaze ukuthuthukiswa kwemboni.
2. Izici ezingathandeki
(1) Ukuncintisana okungalungile emakethe
Uma kuqhathaniswa namanye amaphrojekthi amakhemikhali, isikhathi sokwakhiwa kwephrojekthi ye-cellulose ether sifushane futhi imikhiqizo isetshenziswa kabanzi, ngakho-ke kukhona isenzakalo sokwanda okungenangqondo embonini. Ukwengeza, ngenxa yokuntuleka kwamazinga emboni kanye nezinkambiso zemakethe ezakhiwe uhulumeni, kukhona amabhizinisi amancane anezinga eliphansi lobuchwepheshe kanye nokutshalwa kwezimali okulinganiselwe embonini; abanye babo banezinkinga zokungcoliswa kwemvelo ngamazinga ahlukahlukene enqubo yokukhiqiza, futhi basebenzise izinga eliphansi , Izindleko eziphansi kanye nentengo ephansi elethwa ukutshalwa kwezimali okuphansi kokuvikelwa kwemvelo kube nomthelela emakethe ye-cellulose ether, okubangele isimo sokuncintisana okungahlelekile emakethe. . Ngemuva kokwethulwa kobuchwepheshe obusha nemikhiqizo emisha, indlela yokuqeda imakethe izothuthukisa isimo esikhona sokuncintisana okungahlelekile.
(2) Imikhiqizo yobuchwepheshe obuphezulu kanye nenani eliphakeme ingaphansi kokulawulwa kwamanye amazwe
Imboni yangaphandle ye-cellulose ether yaqala ngaphambi kwesikhathi, futhi amabhizinisi okukhiqiza amelwe yi-Dow Chemical and Hercules Group e-United States asesimweni sokuhola ngokuphelele mayelana nefomula yokukhiqiza nobuchwepheshe. Njengoba zivinjelwe ubuchwepheshe, izinkampani zasekhaya ze-cellulose ether ikakhulukazi zikhiqiza imikhiqizo enenani eliphansi elinemizila yenqubo elula kanye nokuhlanzeka komkhiqizo okuphansi, kuyilapho izinkampani zakwamanye amazwe zilawula imakethe yemikhiqizo ye-cellulose ether enenani eliphakeme ngokusebenzisa izinzuzo zobuchwepheshe; ngakho-ke, Emakethe yasekhaya ye-cellulose ether, imikhiqizo ephezulu idinga ukungeniswa futhi imikhiqizo esezingeni eliphansi ineziteshi zokuthekelisa ezibuthakathaka. Nakuba amandla okukhiqiza embonini ye-cellulose ether yasekhaya akhule ngokushesha, ukuncintisana kwawo emakethe yamazwe ngamazwe abuthakathaka. Ngokuthuthuka kwemboni ye-cellulose ether, imingcele yenzuzo yemikhiqizo ene-value ephansi izoqhubeka nokuncipha, futhi amabhizinisi asekhaya kufanele afune ukuphumelela kwezobuchwepheshe ukuze aphule ukuzimela kwamabhizinisi angaphandle emakethe yemikhiqizo ephezulu.
(3) Ukushintshashintsha kwentengo yezinto ezibonakalayo
Ikotini elicwengekile, impahla eluhlaza eyinhloko yei-cellulose ether, iwumkhiqizo wezolimo. Ngenxa yezinguquko endaweni yemvelo, okukhiphayo kanye nentengo kuzoshintshashintsha, okuzoletha ubunzima ekulungiseni impahla eluhlaza kanye nokulawulwa kwezindleko zezimboni ezansi nomfula.
Ngaphezu kwalokho, imikhiqizo ye-petrochemical efana ne-propylene oxide ne-methyl chloride nayo iyimpahla ebalulekile yokukhiqiza i-cellulose ether, futhi amanani ayo athintwa kakhulu ukushintshashintsha kwemakethe kawoyela ongahluziwe. Izinguquko esimweni sezombangazwe samazwe ngamazwe zivame ukuba nomthelela emananini kawoyela ongahluziwe, ngakho-ke abakhiqizi be-cellulose ether badinga ukubhekana nemiphumela emibi yokushintshashintsha njalo kwentengo kawoyela ekukhiqizeni nasekusebenzeni kwabo.
