1. Nā mea kūpono
(1) Kākoʻo kulekele
Ma ke ʻano he mea hou e pili ana i ka bio a he mea ʻōmaʻomaʻo a pili i ke kaiapuni, ʻo ka hoʻohana nui ʻana oʻEtera cellulosema ke kahua ʻoihana ʻo ia ke ʻano hoʻomohala o ke kūkulu ʻana i kahi kaiāulu aloha kaiapuni a mālama waiwai i ka wā e hiki mai ana. ʻO ka hoʻomohala ʻana o ka ʻoihana e kūlike me ka pahuhopu macro o koʻu ʻāina o ka hoʻokō ʻana i ka hoʻomohala waiwai hoʻomau. Ua hoʻopuka mau ke aupuni Kina i nā kulekele a me nā ana e like me "National Medium and Long-Term Science and Technology Development Plan (2006-2020)" a me "Construction Industry "Twelfth Five-Year Plan" Development Plan" e kākoʻo i ka ʻoihana cellulose ether.
Wahi a ka "2014-2019 China Pharmaceutical Food Grade Cellulose Ether Market Monitoring and Investment Prospect Analysis Report" i hoʻokuʻu ʻia e China Industry Information Network, ua hoʻokumu pū ka ʻāina i nā kūlana palekana kaiapuni koʻikoʻi, kahi i hāpai ai i ke koʻikoʻi ma nā pilikia palekana kaiapuni i kahi pae hou. Ua pāʻani nā hoʻopaʻi nui aʻe no ka haumia kaiapuni i kahi hana maikaʻi i ka hoʻoponopono ʻana i nā pilikia e like me ka hoʻokūkū haunaele ma ka ʻoihana cellulose ether a me ka hoʻohui ʻana i ka hiki ke hana ʻoihana.
(2) He ākea ka manaʻolana o nā noi ma hope a ke piʻi nei ke koi
Ua kapa ʻia ʻo Cellulose ether ʻo "monosodium glutamate ʻoihana" a hiki ke hoʻohana ʻia ma nā ʻano like ʻole o ka hoʻokele waiwai aupuni. ʻO ka hoʻomohala waiwai e hoʻokele pono i ka ulu ʻana o ka ʻoihana cellulose ether. Me ka hoʻomohala mau ʻana o ke kaʻina hana kūlanakauhale o koʻu ʻāina a me ka hoʻopukapuka kālā ikaika o ke aupuni i nā waiwai paʻa a me nā hale kūʻai kūpono, e hoʻonui nui ka ʻoihana kūkulu hale a me nā mea hana hale i ke koi no ka cellulose ether. Ma nā kahua o ka lāʻau lapaʻau a me ka meaʻai, ke piʻi mālie nei ka ʻike o ka poʻe i ke olakino a me ka palekana o ke kaiapuni. ʻO nā huahana cellulose ether ʻino ʻole a ʻaʻole haumia e like me HPMC e pani mālie i nā mea ʻē aʻe e kū nei a hoʻomohala koke. Eia kekahi, ʻo ka hoʻohana ʻana o ka cellulose ether i nā uhi, nā keramika, nā mea hoʻonani, ka ʻili, ka pepa, ka laholio, nā kemika o kēlā me kēia lā a me nā ʻoihana ʻē aʻe e lilo nei i mea ākea.
(3) Hoʻokele ka holomua ʻenehana i ka hoʻomohala ʻana o ka ʻoihana
I ke kahua mua o ka hoʻomohala ʻana o ka ʻoihana cellulose ether o koʻu ʻāina, ʻo ka ionic carboxymethyl cellulose ether (CMC) ka huahana nui. Me ka hana ʻana o ka ionic cellulose ether i hōʻike ʻia e PAC a me ka non-ionic cellulose ether i hōʻike ʻia e HPMC Me ka hoʻomohala ʻana a me ka oʻo ʻana o ke kaʻina hana, ua hoʻonui ʻia ke kahua noi o ka cellulose ether. E pani koke nā ʻenehana hou a me nā huahana hou i nā huahana cellulose ether kuʻuna i ka wā ma mua a paipai i ka hoʻomohala ʻana o ka ʻoihana.
2. Nā mea maikaʻi ʻole
(1) Hoʻokūkū haunaele ma ka mākeke
Ke hoʻohālikelike ʻia me nā papahana kemika ʻē aʻe, he pōkole ka manawa kūkulu o ka papahana cellulose ether a hoʻohana nui ʻia nā huahana, no laila aia kahi hanana o ka hoʻonui haunaele i ka ʻoihana. Eia kekahi, ma muli o ka nele o nā kūlana ʻoihana a me nā kūlana mākeke i hoʻokumu ʻia e ka mokuʻāina, aia kekahi mau ʻoihana liʻiliʻi me ka pae loea haʻahaʻa a me ka hoʻopukapuka kālā palena ʻole i ka ʻoihana; loaʻa i kekahi o lākou nā pilikia haumia kaiapuni i nā kekelē like ʻole i ke kaʻina hana, a hoʻohana i ka maikaʻi haʻahaʻa, ʻO ke kumukūʻai haʻahaʻa a me ke kumukūʻai haʻahaʻa i lawe ʻia mai e ka hoʻopukapuka palekana kaiapuni haʻahaʻa ua hoʻopilikia i ka mākeke cellulose ether, e hopena ana i kahi kūlana o ka hoʻokūkū haunaele ma ka mākeke. Ma hope o ka hoʻolauna ʻana o nā ʻenehana hou a me nā huahana hou, e hoʻomaikaʻi ke ʻano hoʻopau o ka mākeke i ke kūlana o ka hoʻokūkū haunaele.
(2) Aia nā huahana ʻenehana kiʻekiʻe a me nā huahana waiwai nui i hoʻohui ʻia i lalo o ka mana o nā haole
Ua hoʻomaka mua ka ʻoihana cellulose ether haole, a ʻo nā ʻoihana hana i hōʻike ʻia e Dow Chemical lāua ʻo Hercules Group ma ʻAmelika Hui Pū ʻIa aia ma ke kūlana alakaʻi loa ma ke ʻano o ke ʻano hana a me ka ʻenehana. I kaupalena ʻia e ka ʻenehana, hana nui nā ʻoihana cellulose ether kūloko i nā huahana haʻahaʻa-waiwai me nā ala hana maʻalahi a me ka maʻemaʻe huahana haʻahaʻa, ʻoiai ua hoʻopaʻa nā ʻoihana haole i ka mākeke no nā huahana cellulose ether waiwai nui ma ka hoʻohana ʻana i nā pono ʻenehana; no laila, ma ka mākeke cellulose ether kūloko, pono e lawe ʻia mai nā huahana kiʻekiʻe a he nāwaliwali nā kahawai hoʻokuʻu aku i nā huahana haʻahaʻa. ʻOiai ua ulu wikiwiki ka hiki ke hana o ka ʻoihana cellulose ether kūloko, ua nāwaliwali kona hoʻokūkū ma ka mākeke honua. Me ka hoʻomohala ʻana o ka ʻoihana cellulose ether, e hoʻomau ka emi ʻana o nā palena waiwai o nā huahana haʻahaʻa-waiwai, a pono nā ʻoihana kūloko e ʻimi i nā holomua ʻenehana e uhaki i ka monopoly o nā ʻoihana haole ma ka mākeke huahana kiʻekiʻe.
(3) Nā loli o ke kumukūʻai o nā mea maka
ʻO ka pulupulu i hoʻomaʻemaʻe ʻia, ka mea maka nui oʻEtera cellulose, he huahana mahiʻai. Ma muli o nā loli o ke kaiapuni kūlohelohe, e loli ka huahana a me ke kumukūʻai, kahi e lawe mai ai i nā pilikia i ka hoʻomākaukau ʻana i nā mea maka a me ka kaohi ʻana i nā kumukūʻai o nā ʻoihana ma hope.
Eia kekahi, ʻo nā huahana petrochemical e like me ka propylene oxide a me ka methyl chloride he mau mea maka koʻikoʻi no ka hana ʻana o ka cellulose ether, a ua hoʻopilikia nui ʻia ko lākou kumukūʻai e nā loli i ka mākeke aila maka. ʻO nā loli i ke kūlana politika honua e loaʻa pinepine ka hopena i nā kumukūʻai aila maka, no laila pono nā mea hana cellulose ether e kū i nā hopena maikaʻi ʻole o nā loli pinepine i nā kumukūʻai aila i kā lākou hana a me ka hana.
