Cellulose ether imadziwika kuti "industrial monosodium glutamate".Ili ndi maubwino ogwiritsidwa ntchito mosiyanasiyana, kugwiritsa ntchito magawo ang'onoang'ono, kusintha kwabwino, komanso kuyanjana ndi chilengedwe.Itha kuwongolera bwino ndikuwongolera magwiridwe antchito azinthu pazowonjezera zake, zomwe zimathandizira kukonza kagwiritsidwe ntchito kazinthu.Kuchita bwino komanso mtengo wowonjezera wazinthu zimagwiritsidwa ntchito kwambiri m'magawo ambiri monga zida zomangira, mankhwala, chakudya, nsalu, mankhwala atsiku ndi tsiku, kufufuza mafuta, migodi, kupanga mapepala, polymerization ndi zakuthambo, ndipo ndizofunikira kwambiri pakuteteza chilengedwe m'magawo osiyanasiyana azachuma chadziko.Ndi kuyambiranso kwachuma cha dziko langa, kufunikira kwa cellulose ether m'mafakitale akumunsi monga mafakitale omanga, mafakitale opanga chakudya ndi mafakitale opanga mankhwala kumatulutsidwa pang'onopang'ono.Makampaniwa akukula mofulumira ndipo mlingo wa phindu wawonjezeka kwambiri.
Chitukuko chamakampani:
(1) Kukula kwa msika wazinthu zomangira kalasi ya cellulose ether: Chifukwa chakusintha kwakukula kwa mizinda ya dziko langa, makampani opanga zida zomangira atukuka mwachangu, kuchuluka kwa makina omangira kwasinthidwa mosalekeza, ndipo ogula ali ndi chitetezo chambiri komanso chapamwamba. zofunikira za zida zomangira, zomwe zapangitsa kuti pakhale kufunikira kwa ether yopanda ma ionic cellulose m'munda wa zida zomangira.Ndemanga ya Ndondomeko ya Zaka khumi ndi Zitatu ya National Economic and Social Development ikufuna kufulumizitsa kukonzanso matawuni ang'onoang'ono a m'tauni ndi nyumba zowonongeka, komanso kulimbikitsa ntchito zomangamanga m'mizinda.Kuphatikizirapo: kumalizidwa koyambira kwa midzi ya m'tauni ndi ntchito zokonzanso nyumba zomwe zidawonongeka.Kufulumizitsa kusintha kwa matauni ndi midzi ya m'tauni, ndi kulimbikitsa mwadongosolo kuwongolera bwino kwa malo okhalamo akale, kukonzanso nyumba zowonongeka ndi zosamalizidwa, ndi ndondomeko ya kusintha kwa midzi ya m'tauni ikukhudza matauni akuluakulu m'dziko lonselo.Kufulumizitsa kusintha ndi kumanga malo operekera madzi m'mizinda;kulimbikitsa kusintha ndi kumanga maziko apansi panthaka monga maukonde a mapaipi a tauni.
Kuphatikiza apo, pa February 14, 2020, msonkhano wa khumi ndi ziwiri wa Central Committee for Comprehensively Deepening Reform unanena kuti "zomangamanga zatsopano" ndizomwe zimayang'anira ntchito yomanga dziko langa m'tsogolomu.Msonkhanowo unanena kuti "zomangamanga ndizofunikira kwambiri pa chitukuko cha zachuma ndi chikhalidwe cha anthu.Motsogozedwa ndi mgwirizano ndi kuphatikiza, kugwirizanitsa chitukuko cha masheya ndi zowonjezera, zachikhalidwe ndi zatsopano, ndikupanga njira zamakono zamakono, zogwira mtima, zachuma, zanzeru, zobiriwira, zotetezeka komanso zodalirika."Kukhazikitsidwa kwa "zomangamanga zatsopano" kumathandizira kupititsa patsogolo kutukuka kwa mizinda ya dziko langa motsogozedwa ndi nzeru ndi ukadaulo, ndipo ndikoyenera kukulitsa kufunikira kwapakhomo pazomangamanga zama cellulose ether.
(2) Kukula kwa msika wamankhwala amtundu wa cellulose ethers: ma cellulose ethers amagwiritsidwa ntchito kwambiri popaka filimu, zomatira, kukonzekera filimu, mafuta odzola, dispersants, makapisozi a masamba, kukonzekera kosalekeza ndi kuwongolera kumasulidwa ndi magawo ena amankhwala.Monga chigoba chakuthupi, cellulose ether ali ndi ntchito zotalikitsa nthawi yamankhwala ndikulimbikitsa kubalalitsidwa ndi kutha kwa mankhwala;monga kapisozi ndi zokutira, zimatha kupewa kuwonongeka ndi kulumikizana ndi kuchiritsa machitidwe, ndipo ndizofunikira kwambiri popanga zopangira mankhwala.Tekinoloje yogwiritsira ntchito mankhwala a pharmaceutical grade cellulose ether ndi okhwima m'mayiko otukuka.
①Pharmaceutical-grade HPMC ndiye chinthu chachikulu chopangira makapisozi a masamba a HPMC, ndipo kufunikira kwa msika kuli ndi kuthekera kwakukulu.Mankhwala kalasi HPMC ndi chimodzi mwa zinthu zazikulu zopangira kupanga HPMC masamba makapisozi, mlandu oposa 90% ya zipangizo kupanga HPMC masamba makapisozi.The HPMC masamba makapisozi opangidwa ndi ubwino chitetezo ndi ukhondo, applicability lonse, palibe chiopsezo cholumikizira mtanda zimachitikira, ndi kukhazikika mkulu.Poyerekeza ndi makapisozi a gelatin a nyama, makapisozi a mbewu safunikira kuwonjezera zoteteza popanga, ndipo amakhala osalimba pansi pa chinyezi chochepa, ndipo amakhala ndi chipolopolo chokhazikika cha kapisozi m'malo achinyezi.Chifukwa cha zabwino zomwe tatchulazi, makapisozi a zomera amalandiridwa ndi mayiko otukuka ku Ulaya ndi United States ndi mayiko achisilamu.
Kupanga kwakukulu kwa makapisozi a masamba a HPMC kumakhala ndi zovuta zina zaukadaulo, ndipo maiko otukuka adziwa njira zamakono zopangira makapisozi a masamba.Pali mabizinesi ochepa omwe amapanga makapisozi a zomera za HPMC m'dziko langa, ndipo kuyambira kwachedwa, ndipo kutulutsa kwa makapisozi a chomera cha HPMC ndikocheperako.Pakali pano, mfundo za dziko langa zopezera makapisozi a zomera za HPMC sizinadziwikebe.Kugwiritsa ntchito makapisozi a mbewu ya HPMC pamsika wapakhomo ndikochepa kwambiri, kuwerengera gawo lotsika kwambiri la makapisozi opanda kanthu.Ndikovuta kusinthiratu makapisozi a gelatin a nyama kwakanthawi kochepa.
Mu Epulo 2012 ndi Marichi 2014, atolankhani adawulula motsatizana zomwe zidachitika kuti mafakitole ena am'nyumba zamakapisozi adagwiritsa ntchito gelatin yopangidwa kuchokera ku zinyalala zachikopa monga zopangira kupanga makapisozi okhala ndi zitsulo zolemera kwambiri monga chromium, zomwe zidapangitsa ogula kudalira mankhwala ndi gelatin yodyedwa. zovuta.Izi zitachitika, boma lidafufuza ndikuthana ndi mabizinesi angapo omwe amapanga mosaloledwa ndikugwiritsa ntchito makapisozi osayenera, ndipo kuzindikira kwa anthu zachitetezo chazakudya ndi mankhwala kwapita patsogolo, zomwe zimathandizira kuti ntchito yokhazikika komanso kukweza kwa mafakitale kumakampani am'nyumba a gelatin. .Zikuyembekezeka kuti makapisozi azitsamba azikhala amodzi mwamagawo ofunikira pakukweza msika wa kapisozi wopanda kanthu mtsogolomo, ndipo akhale malo okulirapo pakufunika kwa HPMC yamagulu azamankhwala pamsika wapakhomo mtsogolomo.
②Pharmaceutical grade cellulose ether ndiye chinthu chofunikira kwambiri popanga mankhwala okhazikika komanso oyendetsedwa bwino.Pharmaceutical grade cellulose ether ndi imodzi mwazinthu zofunika kwambiri popanga kukonzekera kokhazikika komanso koyendetsedwa bwino, komwe kumagwiritsidwa ntchito kwambiri popanga mankhwala m'maiko otukuka.Kukonzekera kosalekeza kumatha kuzindikira zotsatira za kumasulidwa kwapang'onopang'ono kwa mankhwala, ndipo kukonzekera kumasulidwa kolamulidwa kungazindikire zotsatira za kulamulira nthawi yotulutsidwa ndi mlingo wa zotsatira za mankhwala.Kukonzekera kokhazikika komanso koyendetsedwa kungathe kusunga mankhwala osokoneza bongo m'magazi a wogwiritsa ntchito mokhazikika, kuthetsa poizoni ndi zotsatira zoyipa zomwe zimachitika chifukwa cha nsonga ndi chigwa cha ndende ya mankhwala a magazi chifukwa cha mayamwidwe a mankhwala wamba, kutalikitsa nthawi ya mankhwala, kuchepetsa kuchuluka kwa nthawi ndi mlingo wa mankhwala, ndi bwino lapamwamba la mankhwala.Onjezani mtengo wowonjezera wamankhwala ndi malire akulu.Kwa nthawi yayitali, ukadaulo wopangira zida za HPMC (CR grade) pokonzekera kutulutsidwa koyendetsedwa kwakhala m'manja mwa makampani angapo odziwika padziko lonse lapansi, ndipo mtengo wake ndi wokwera mtengo, womwe waletsa kukwezedwa ndi kugwiritsa ntchito zinthu ndi kukweza. zamakampani azamankhwala akudziko langa.Kupangidwa kwa ma cellulose ethers kuti amasulidwe pang'onopang'ono komanso mowongolera kumathandizira kupititsa patsogolo kukweza kwamakampani opanga mankhwala mdziko langa ndipo ndikofunikira kwambiri kuteteza miyoyo ndi thanzi la anthu.
Panthawi imodzimodziyo, malinga ndi "Industrial Structure Adjustment Guidance Catalog (2019 Version)", "kupanga ndi kupanga mitundu yatsopano ya mlingo wa mankhwala, zowonjezera zatsopano, mankhwala a ana, ndi mankhwala opereŵera" alembedwa monga momwe amalimbikitsidwira.Chifukwa chake, makapisozi amtundu wa cellulose ether ndi HPMC amagwiritsidwa ntchito ngati kukonzekera kwamankhwala ndi zowonjezera zatsopano, zomwe zikugwirizana ndi kayendetsedwe ka chitukuko chamakampani adziko lonse, ndipo kufunikira kwa msika kukuyembekezeka kupitiliza kukwera mtsogolo.
(3) Kukula kwa msika wa ether ya cellulose ether: Food grade cellulose ether ndi chowonjezera chodziwika bwino cha chakudya, chomwe chitha kugwiritsidwa ntchito ngati chowonjezera chakudya, chokhazikika komanso chonyowa kuti chikhale chokhuthala, kusunga madzi, ndikuwongolera kukoma.Dzikoli lakhala likugwiritsidwa ntchito kwambiri, makamaka pa zinthu zophikidwa, ma collagen casings, zonona za mkaka, madzi a zipatso, sauces, nyama ndi zakudya zina zamapuloteni, zakudya zokazinga, etc. China, United States, European Union ndi mayiko ena ambiri amalola. HPMC ndi ionic cellulose ether CMC kuti zigwiritsidwe ntchito ngati zowonjezera chakudya.
Chigawo cha cellulose ether chomwe chimagwiritsidwa ntchito popanga chakudya m'dziko langa ndi chochepa.Chifukwa chachikulu ndikuti ogula apakhomo adayamba mochedwa kuti amvetsetse ntchito ya cellulose ether ngati chowonjezera cha chakudya, ndipo akadali pagawo logwiritsira ntchito ndikulimbikitsa pamsika wapakhomo.Kuphatikiza apo, mtengo wa chakudya chamagulu a cellulose ether ndiokwera kwambiri.Pali malo ochepa omwe amagwiritsidwa ntchito popanga.Ndi kusintha kwa chidziwitso cha anthu pazakudya zopatsa thanzi, kumwa kwa cellulose ether m'makampani azakudya zapakhomo akuyembekezeka kuwonjezeka kwambiri.
