Kugwiritsiridwa ntchito kwa cellulose ether ndikokwanira kwambiri, ndipo chitukuko chonse cha chuma cha dziko chidzayendetsa mwachindunji chitukuko cha mafakitale a cellulose ether. Pakali pano, ntchito yacellulose etherku China kumapezeka makamaka m'mafakitale monga zomangira, kubowola mafuta ndi mankhwala. Ndi kugwiritsa ntchito ndi kukwezedwa kwa cellulose ether m'malo ena, kufunikira kwa cellulose ether m'mafakitale akumunsi kudzakula mwachangu.
Kuonjezera apo, kuwonjezeka kwa ndalama za dziko mu zomangamanga zokhazikika ndi chitukuko cha mphamvu, komanso kumanga midzi ya dzikoli, komanso kuwonjezeka kwa anthu okhala m'nyumba, thanzi ndi madera ena, zidzakhala ndi zotsatira zabwino pa cellulose ether kupyolera mu kayendetsedwe ka zipangizo zomangira, kubowola mafuta ndi mafakitale ogulitsa mankhwala. Kukula kwamakampani kumabweretsa kukoka kosalunjika.
Mtengo wa HPMCmankhwala zimagwiritsa ntchito m'madera osiyanasiyana a chuma cha dziko mu mawonekedwe a zina, kotero HPMC ali ndi makhalidwe a mowa lonse ndi kumwa kumwazikana, ndi owerenga kunsi kwa mtsinje makamaka kugula pang'ono. Kutengera mawonekedwe a ogwiritsa ntchito omwe amwazikana pamsika, malonda a HPMC nthawi zambiri amatengera mtundu wa ogulitsa.
Nonionic cellulose ethers amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala monga zopangira mankhwala, monga thickeners, dispersants, emulsifiers ndi opanga mafilimu. Amagwiritsidwa ntchito popaka filimu ndi zomatira pamapiritsi a mankhwala, ndipo angagwiritsidwenso ntchito kuyimitsidwa, kukonzekera maso, kumasulidwa kosalekeza ndi kuyendetsedwa kwa matrix oyandama, etc. Poyerekeza ndi magulu ena a zinthu za cellulose ether, kusonkhanitsa kwa zinthu zomalizidwa kumakhala kochepa, mtengo wopangira ndi wokwera, ndipo mtengo wowonjezera wa mankhwalawa ndi wokwera kwambiri. apamwamba.
Pakalipano, othandizira mankhwala achilendo amawerengera 10-20% ya mtengo wamtengo wapatali wa mankhwala onse. Popeza kuti mankhwala opangira mankhwala a dziko langa anayamba mochedwa ndipo mlingo wonsewo ndi wochepa, operekera mankhwala apakhomo amakhala ndi gawo lochepa la mankhwala onse, pafupifupi 2-3%. Zothandizira pazamankhwala zimagwiritsidwa ntchito kwambiri pokonzekera zinthu monga kukonzekera mankhwala, mankhwala a patent aku China ndi mankhwala am'chilengedwe. Kuchokera mchaka cha 2008 mpaka 2012, kuchuluka kwa mankhwala opangira mankhwala kunali yuan biliyoni 417.816, yuan biliyoni 503.315, yuan biliyoni 628.713, 887.957 biliyoni ndi yuan 1,053.953 biliyoni motsatana. Malinga ndi kuchuluka kwa mankhwala m'dziko langa excipients mankhwala mlandu 2% ya okwana linanena bungwe mtengo wa kukonzekera mankhwala, okwana linanena bungwe mtengo wa excipients zoweta mankhwala kuchokera 2008 mpaka 2012 anali za 8 biliyoni, 10 biliyoni yuan, 12.5 biliyoni 8 biliyoni yuan 1 biliyoni 21.
Pa nthawi ya "Mapulani a Zaka khumi ndi ziwiri", Unduna wa Sayansi ndi Ukadaulo unaphatikizanso matekinoloje ofunikira opangira zida zatsopano zopangira mankhwala ngati mitu yofufuza. Mu "Pulogalamu ya 12 yazaka zisanu zachitukuko chamakampani opanga mankhwala" yoperekedwa ndi Unduna wa Zamakampani ndi Upangiri Waukadaulo, kulimbikitsa chitukuko ndi kugwiritsa ntchito zida zatsopano zopangira mankhwala ndi zida zoyikamo zidalembedwa ngati gawo lofunikira kwambiri pakukula kwamakampani opanga mankhwala. Mogwirizana ndi cholinga cha kukula kwapakati pachaka kwa 20% pamtengo wokwanira wamakampani opanga mankhwala mu "Mapulani a Zaka khumi ndi ziwiri" za Unduna wa Zamakampani ndi Ukadaulo waukadaulo, kukula kwa msika wazinthu zothandizira mankhwala kudzakula mwachangu mtsogolomo, ndipo nthawi yomweyo kulimbikitsa kukula kwa kalasi yamankhwala.Mtengo wa HPMCmsika.
