Kodi zopinga zazikulu zolowera mumakampani a ether a cellulose ndi ziti?

(1) Zopinga zaukadaulo

Makasitomala otsika aether ya celluloseali ndi zofunikira zapamwamba pa khalidwe ndi kukhazikika kwa ether ya cellulose. Ukadaulo wowongolera khalidwe ndi chotchinga chofunikira kwambiri chaukadaulo mumakampani opanga ether ya cellulose. Opanga amafunika kudziwa bwino magwiridwe antchito ofanana ndi kapangidwe ka zida zapakati, kuwongolera magawo ofunikira pakupanga, njira zopangira pakati, kupanga miyezo yogwirira ntchito, ndipo atatha nthawi yayitali yokonza zolakwika ndikusintha kosalekeza kwaukadaulo, amatha kupanga ether ya cellulose yokhazikika komanso yapamwamba; Pokhapokha titagwiritsa ntchito ndalama zambiri zofufuzira ndikupeza chidziwitso chokwanira pantchito yogwiritsira ntchito. N'zovuta kuti mabizinesi atsopano omwe akulowa mumakampaniwa azitha kudziwa bwino ukadaulo wapakati munthawi yochepa. Kuti azitha kupanga bwino kwambiri ma ether a cellulose okhala ndi mankhwala ndi chakudya okhala ndi khalidwe lokhazikika (makamaka ma ether a cellulose kuti atuluke pang'onopang'ono komanso molamulidwa), zimafunikanso ndalama zina zofufuzira ndi chitukuko kapena nthawi yosonkhanitsa chidziwitso. Chifukwa chake, pali zopinga zina zaukadaulo mumakampani awa.

(2) Zopinga pa luso la akatswiri

Pakupanga ndi kugwiritsa ntchito cellulose ether, pali zofunikira kwambiri pa khalidwe ndi luso la akatswiri, ogwira ntchito ndi oyang'anira. Akatswiri ndi ogwira ntchito ofunikira amakhalabe okhazikika. N'zovuta kwa anthu ambiri atsopano kupeza maluso aukadaulo pogwiritsa ntchito R&D ndi ukadaulo wofunikira pakapita nthawi yochepa, ndipo pali zopinga za akatswiri aluso.

(3) Zopinga zoyenereza

Makampani opanga ma cellulose ether ayenera kupeza ziyeneretso zoyenera kuti apange ndikugulitsa ma cellulose ether a mankhwala a grade grade ndi ma cellulose ether a chakudya.

Pakati pawo, mankhwala a cellulose ether ndi chinthu chofunikira kwambiri chogwiritsira ntchito mankhwala, ndipo ubwino wake umakhudza mwachindunji chitetezo cha mankhwala. Pofuna kuonetsetsa kuti mankhwala ndi otetezeka, dziko langa likugwiritsa ntchito njira yopezera zilolezo zopangira mankhwala. Pofuna kulimbikitsa kuyang'anira makampani opanga mankhwala, boma lapanga malamulo ndi malangizo okhudzana ndi kupeza, kupanga ndi kugwiritsa ntchito makampani. Malinga ndi "Kalata Yosindikiza ndi Kugawa Zofunikira pa Kulembetsa ndi Kugwiritsa Ntchito Mankhwala Owonjezera" yoperekedwa ndi Boma la Chakudya ndi Mankhwala, kasamalidwe ka chilolezo chopangira mankhwala owonjezera mankhwala kakugwiritsidwa ntchito, ndipo mankhwala atsopano owonjezera mankhwala ndi mankhwala owonjezera ochokera kunja akuyenera kuvomerezedwa ndi National Bureau. Pali kale mankhwala owonjezera mankhwala ovomerezeka ndi boma omwe avomerezedwa ndi ofesi ya boma. Kuyang'anira mankhwala owonjezera mankhwala m'boma kukukulirakulira, ndipo madera ndi mizinda yosiyanasiyana yapanga njira zoyendetsera mogwirizana ndi "Njira Zoyendetsera Mankhwala Owonjezera (Draft for Comment)" yoperekedwa ndi boma. Mtsogolomu, ngati mabizinesi sangathe kupanga zinthu zothandizira mankhwala motsatira miyezo ya dziko, sangathe kulowa mumsika. Asanasankhe kapena kusintha mtundu wina kapena mtundu wa ether ya cellulose ya mankhwala, opanga mankhwala ayenera kupita kukayang'anira ndikupereka kwa akuluakulu oyenerera asanagule ndikuigwiritsa ntchito mwalamulo. Pali zopinga zina pakuvomerezedwa kwa opanga mankhwala kwa ogulitsa. . Kampaniyo ikangolandira "Layisensi Yopanga Zinthu Zamakampani Yadziko Lonse" yoperekedwa ndi Provincial Bureau of Quality and Technical Supervision, imatha kuvomerezedwa kupanga ether ya cellulose ngati chowonjezera cha chakudya.

Malinga ndi malamulo oyenera monga "Malamulo Ogwirizana Okhudza Kulimbitsa Kuyang'anira ndi Kuyang'anira Zopangira Mankhwala" omwe adaperekedwa ndi Boma la Food and Drug Administration pa Ogasiti 1, 2012, mabizinesi ayenera kupeza "Chilolezo Chopanga Mankhwala" kuti apange makapisozi a chomera cha HPMC, ndipo mitunduyo iyenera kupeza chilolezo cholembetsa cha dziko lonse choperekedwa ndi Bungwe.

(4) Zopinga zandalama

Kupanga kwa cellulose ether kumakhala ndi zotsatira zoonekeratu pamlingo waukulu. Zipangizo zazing'ono zomwe zimagwiritsidwa ntchito pamanja zimakhala ndi mphamvu zochepa zotulutsa, kukhazikika kwabwino, komanso chitetezo chochepa chopanga. Chipangizo chachikulu chowongolera chokha chimapangitsa kuti zinthu zikhazikike bwino komanso kuti zinthu zizikhala bwino. Zipangizo zambiri zodziyimira zokha zimafuna ndalama zambiri. Kuti zinthu ziyende bwino, mabizinesi ayenera kupitiliza kuyika ndalama pakukulitsa mphamvu zopanga ndikuwonjezera ndalama zofufuzira ndi chitukuko. Oyamba kumene ayenera kukhala ndi mphamvu zachuma kuti apikisane ndi makampani omwe alipo ndikukumana ndi zopinga zina zachuma kuti alowe mumakampani.

(5) Zopinga zachilengedwe

Njira yopangiraether ya celluloseadzapanga madzi otayira ndi mpweya wotayira, ndipo zida zotetezera chilengedwe pochiza madzi otayira ndi mpweya wotayira zili ndi ndalama zambiri, zofunikira kwambiri paukadaulo komanso ndalama zambiri zogwirira ntchito. Pakadali pano, mfundo zoteteza chilengedwe m'nyumba zikukulirakulira, zomwe zimayika patsogolo zofunikira kwambiri paukadaulo woteteza chilengedwe ndi ndalama zogulira cellulose ether, zomwe zimawonjezera ndalama zopangira mabizinesi ndikupanga chotchinga chachikulu choteteza chilengedwe. Mabizinesi opanga cellulose ether omwe ali ndi ukadaulo woteteza chilengedwe komanso kuipitsa kwakukulu adzakumana ndi vuto loti achotsedwe. Makasitomala apamwamba ali ndi zofunikira zapamwamba zoteteza chilengedwe kwa opanga cellulose ether. Zikuvuta kwambiri kwa makampani omwe sakwaniritsa miyezo yoteteza chilengedwe kuti apeze ziyeneretso zoperekera makasitomala apamwamba.
