I-Cellulose ether yaziwa ngokuthi "i-industrial monosodium glutamate".Inezinzuzo zokusetshenziswa okubanzi, ukusetshenziswa kweyunithi encane, umphumela omuhle wokuguqula, kanye nobungane bemvelo.Ingathuthukisa kakhulu futhi ithuthukise ukusebenza komkhiqizo emkhakheni wokwengezwa kwawo, okulungele ukuthuthukisa ukusetshenziswa kwezinsiza.Ukusebenza kahle kanye nenani elingeziwe lomkhiqizo lisetshenziswa kabanzi emikhakheni eminingi efana nezinto zokwakha, imithi, ukudla, izindwangu, amakhemikhali ansuku zonke, ukuhlola uwoyela, izimayini, ukwenza iphepha, i-polymerization kanye ne-aerospace, futhi kuyizithasiselo ezibaluleke kakhulu zokuvikela imvelo emikhakheni ehlukahlukene yomnotho wezwe.Ngokusimama komnotho wezwe lami, isidingo se-cellulose ether ezimbonini ezisezansi nomfula njengemboni yezokwakha, imboni yokukhiqiza ukudla kanye nemboni yokukhiqiza imithi siyakhululwa kancane kancane.Imboni ithuthuke ngokushesha futhi izinga lenzuzo likhuphuke kakhulu.
Ithrendi yokuthuthukiswa komkhakha:
(1) Indlela yokuthuthukiswa kwemakethe yezinto zokwakha ezisezingeni le-cellulose ether: Ngenxa yokuthuthuka kwezinga lezwe lami lokufudukela emadolobheni, imboni yempahla yokwakha iye yathuthuka ngokushesha, izinga lokusebenzisa imishini yokwakha liye lathuthukiswa ngokuqhubekayo, futhi abathengi banokuvikelwa kwemvelo okuphezulu nangaphezulu. izidingo zezinto zokwakha, eziqhube isidingo se-non-ionic cellulose ether emkhakheni wezinto zokwakha.Uhlaka loHlelo Lweminyaka Eyishumi Nantathu Lweminyaka Eyishumi Nantathu Lokuthuthukiswa Komnotho Kazwelonke Nezenhlalakahle luhlongoza ukusheshisa ukulungiswa kwamadolobha asemadolobheni anemijondolo kanye nezindlu ezigugile, futhi kuqiniswe ukwakhiwa kwengqalasizinda yasemadolobheni.Kubandakanya: ukuqedwa okuyisisekelo kwemijondolo yasemadolobheni kanye nemisebenzi yokulungiswa kwezindlu eziwohlokayo.Ukusheshisa ukuguqulwa kwamadolobhana aminyene kanye namadolobhana asemadolobheni, futhi akhuthaze ngokuhlelekile ukuthuthukiswa okuphelele kwezindawo zokuhlala ezindala, ukulungiswa kwezindlu ezigugile nezingaqediwe, kanye nenqubomgomo yokuguqulwa kwemijondolo ihlanganisa amadolobha amakhulu ezweni lonke.Ukusheshisa uguquko kanye nokwakhiwa kwezinsiza zokuhlinzeka ngamanzi emadolobheni;ukuqinisa uguquko nokwakhiwa kwengqalasizinda engaphansi komhlaba efana noxhaxha lwamapayipi kamasipala.
Ukwengeza, ngoFebhuwari 14, 2020, umhlangano weshumi nambili weKomidi Eliyinhloko Lezinguquko Ezijulisa Kakhulu waveza ukuthi “ingqalasizinda entsha” iwumhlahlandlela wokwakhiwa kwengqalasizinda yezwe lami esikhathini esizayo.Umhlangano uphakamise ukuthi “ingqalasizinda iwusekelo olubalulekile ekuthuthukisweni komnotho nezenhlalakahle.Iqondiswa ukusebenzisana nokuhlanganiswa, iqondisa ukuthuthukiswa kwengqalasizinda yezimpahla kanye nentuthuko ekhulayo, yendabuko kanye nentsha, futhi yakhe uhlelo lwengqalasizinda lwesimanje oluqinile, olusebenzayo, olongayo, oluhlakaniphile, oluluhlaza, oluphephile noluthembekile.”Ukuqaliswa “kwengqalasizinda entsha” kusiza ekuthuthukisweni kokukhula kwezwe lami emadolobheni ngendlela yezobunhloli nobuchwepheshe, futhi kusiza ekwandiseni isidingo sasekhaya sezinto zokwakha ezisezingeni le-cellulose ether.
(2) Umkhuba wokuthuthukiswa kwemakethe wama-ethers e-cellulose ebangeni lezemithi: ama-cellulose ethers asetshenziswa kabanzi ekwakhiweni kwefilimu, izinto zokunamathisela, ukulungiswa kwefilimu, okokugcoba, okusabalalisa, amaphilisi emifino, amalungiselelo okukhululwa aqhubekayo futhi alawulwayo kanye neminye imikhakha yemithi.Njengempahla yohlaka lwamathambo, i-cellulose ether inemisebenzi yokwelula isikhathi somphumela wezidakamizwa kanye nokugqugquzela ukuhlakazwa nokuqedwa kwezidakamizwa;njenge-capsule kanye ne-coating, ingagwema ukuwohloka kanye nokuxhumanisa nokuphulukisa ukusabela, futhi iyimpahla ebalulekile yokukhiqiza izinto ezisizayo zemithi.Ubuchwepheshe bokusetshenziswa kwe-ether ye-cellulose ether yezinga lezemithi buvuthiwe emazweni athuthukile.
①I-HPMC ye-Pharmaceutical-grade iwukusetshenziswa okuyinhloko kokukhiqizwa kwamaphilisi emifino e-HPMC, futhi isidingo semakethe sinamandla amakhulu.Ibanga lezemithi i-HPMC ingenye yezinto zokusetshenziswa eziyinhloko zokukhiqiza amaphilisi emifino e-HPMC, ebalwa ngaphezu kuka-90% wezinto zokusetshenziswa zokukhiqiza amaphilisi emifino e-HPMC.Amaphilisi emifino e-HPMC akhiqizwayo anezinzuzo zokuphepha nenhlanzeko, ukusetshenziswa okubanzi, akukho bungozi bokusabela okuxhumanisa, kanye nokuzinza okuphezulu.Uma kuqhathaniswa nama-capsules we-gelatin yezilwane, ama-capsules ezitshalo awadingi ukwengeza izilondolozi ohlelweni lokukhiqiza, futhi cishe awabiki ngaphansi kwezimo zomswakama ophansi, futhi anezakhiwo ezizinzile zegobolondo le-capsule ezindaweni ezinomswakama ophezulu.Ngenxa yezinzuzo ezishiwo ngenhla, amaphilisi ezitshalo amukelwa amazwe athuthukile eYurophu nase-United States namazwe amaSulumane.
Ukukhiqizwa okukhulu kwamaphilisi emifino e-HPMC kunobunzima obuthile bezobuchwepheshe, futhi amazwe athuthukile asekwazi kahle ubuchwepheshe obufanele bokukhiqiza amaphilisi emifino.Kukhona amabhizinisi ambalwa abambe iqhaza ekukhiqizeni amaphilisi ezitshalo ze-HPMC ezweni lami, futhi ukuqala sekuphuzile kakhulu, futhi ukukhishwa kwamaphilisi ezitshalo ze-HPMC kuncane kakhulu.Okwamanje, inqubomgomo yezwe lami yokufinyelela yamaphilisi ezitshalo ze-HPMC ayikacaci.Ukusetshenziswa kwamaphilisi ezitshalo ze-HPMC emakethe yasekhaya kuncane kakhulu, kubala ingxenye ephansi kakhulu yokusetshenziswa okuphelele kwamaphilisi angenalutho.Kunzima ukushintsha ngokuphelele amaphilisi e-gelatin yezilwane esikhathini esifushane.
Ngo-April 2012 kanye nango-March 2014, abezindaba badalula ngokulandelana isigameko sokuthi ezinye izimboni ezikhiqiza imithi yasekhaya zasebenzisa i-gelatin ekhiqizwe emfucumfucwini yesikhumba njengempahla eluhlaza ukuze kukhiqizwe amaphilisi anensimbi esindayo ngokweqile njenge-chromium, okuvuse ukuthembela kwabathengi egelatin yokwelapha nedliwayo. isimo esibucayi.Ngemuva kwalesi sigameko, umbuso uphenye futhi wabhekana nenqwaba yamabhizinisi akhiqiza futhi asebenzisa amaphilisi angafaneleki ngokungemthetho, futhi ukuqwashisa komphakathi ngokuphepha kokudla nezidakamizwa kuye kwaba ngcono nakakhulu, okuhambisana nokusebenza okujwayelekile kanye nokuthuthukiswa kwezimboni zemboni yasekhaya ye-gelatin. .Kulindeleke ukuthi amaphilisi ezitshalo abe ngenye yezinkomba ezibalulekile zokuthuthukiswa kwemboni ye-capsule eyize ngokuzayo, futhi kuzoba yindawo enkulu yokukhula kwesidingo se-HPMC yebanga lezemithi emakethe yasekhaya ngokuzayo.
②I-ether ye-cellulose ether yezinga lezemithi iwukhiye wokusebenza wokukhiqiza amalungiselelo okukhululwa aqhubekayo nalawulwayo.I-ether ye-cellulose ether yezinga lemithi ingenye yezinto zokusetshenziswa ezibalulekile zokukhiqizwa kwamalungiselelo okukhululwa okuqhubekayo futhi okulawulwayo, asetshenziswa kakhulu ekukhiqizweni kwezidakamizwa emazweni athuthukile.Amalungiselelo okukhishwa okuqhubekayo angabona umthelela wokukhishwa kancane komthelela wezidakamizwa, futhi amalungiselelo okukhishwa okulawulwayo angabona umphumela wokulawula isikhathi sokukhishwa kanye nomthamo womthelela wesidakamizwa.Ukulungiswa kokukhululwa okuqhubekayo futhi okulawulwayo kungagcina ukugcwala kwezidakamizwa egazini lomsebenzisi kuzinzile, kususe ubuthi nemiphumela engemihle ebangelwa ukuphakama kanye nesigodi sokuhlushwa kwezidakamizwa egazini okubangelwa izici zokumuncwa zamalungiselelo ajwayelekile, andise isikhathi sokuthatha izidakamizwa, ukunciphisa inani lezikhathi kanye nomthamo womuthi, futhi uthuthukise ukusebenza kahle komuthi.Khulisa inani elengeziwe lemithi ngemajini enkulu.Isikhathi eside, ubuchwepheshe bokukhiqiza obuyinhloko be-HPMC (ibanga le-CR) lamalungiselelo okukhishwa okulawulwayo bebusezandleni zezinkampani ezimbalwa ezidumile emhlabeni jikelele, futhi intengo iyabiza, okuvimbele ukukhushulwa nokusebenzisa imikhiqizo kanye nokuthuthukiswa. embonini yezemithi yezwe lami.Ukuthuthukiswa kwama-cellulose ethers ukuze akhishwe kancane futhi okulawulwayo kunomthelela ekusheshiseni ukuthuthukiswa kwemboni yezemithi yezwe lami futhi kubaluleke kakhulu ekuvikeleni izimpilo nempilo yabantu.
Ngesikhathi esifanayo, ngokwe-“Industrial Structure Adjustment Guidance Catalogue (2019 Version)”, “ukwakhiwa nokukhiqizwa kwamafomu amasha omthamo wezidakamizwa, izinto ezisizayo ezintsha, izidakamizwa zezingane, nezidakamizwa ezishodayo” kufakwa ohlwini njengokukhuthazwayo.Ngakho-ke, amaphilisi e-cellulose ether ebangeni lezemithi kanye namaphilisi esitshalo se-HPMC asetshenziswa njengamalungiselelo emithi kanye nezinto ezisizayo ezintsha, ezihambisana nesiqondiso sokuthuthukiswa kwemboni kazwelonke, futhi inkambiso yokufunwa kwemakethe kulindeleke ukuthi iqhubeke nokukhuphuka ngokuzayo.
(3) Indlela yokuthuthukiswa kwemakethe ye-ether ye-cellulose yezinga lokudla: I-cellulose ether ye-Food-grade iyisengezo esibonakalayo sokudla esiphephile, esingasetshenziswa njengesigxivizo sokudla, isinzisi nesithambisa ukuze kushube, kugcinwe amanzi, futhi kuthuthukiswe ukunambitheka.Izwe selisetshenziswa kakhulu, ikakhulukazi izinto ezibhakwayo, ama-collagen casings, ukhilimu ongewona wobisi, amajusi ezithelo, amasoso, inyama neminye imikhiqizo yamaprotheni, ukudla okuthosiwe, njll. I-China, i-United States, i-European Union namanye amazwe amaningi avumela. I-HPMC kanye ne-ionic cellulose ether CMC ezosetshenziswa njengezithasiselo zokudla.
Ingxenye ye-cellulose ether yezinga lokudla esetshenziswa ekukhiqizweni kokudla ezweni lami iphansi kakhulu.Isizathu esiyinhloko ukuthi abathengi basekhaya baqale sekwephuzile ukuqonda umsebenzi we-cellulose ether njengesithako sokudla, futhi kusesesiteji sokufaka isicelo nokukhuthazwa emakethe yasekhaya.Ngaphezu kwalokho, intengo ye-cellulose ether yezinga lokudla iphezulu uma kuqhathaniswa.Kunezindawo ezimbalwa ezisetshenziswa ekukhiqizeni.Ngokuthuthukiswa kokuqwashisa kwabantu ngokudla okunempilo, ukusetshenziswa kwe-cellulose ether embonini yokudla yasekhaya kulindeleke ukuthi kuqhubeke kwanda.
