Pehea ke kūlana kūʻai kūloko a me nā ʻāina ʻē o non-ionic cellulose ether?

(1)Ka ʻike o ka mākeke nonionic cellulose ether honua:

Mai ka hiʻohiʻona o ka hāʻawi ʻana i ka mana hana honua, 43% o ka nui o ka honuacellulose eteraʻO ka hana ma 2018 mai Asia mai (ʻo Kina ka 79% o ka hana ʻana o ʻAsia), ʻo ʻEulopa ʻEulopa he 36%, a ʻo ʻAmelika ʻĀkau he 8%. Mai ka hiʻohiʻona o ka noi cellulose ether honua, ʻo ka hoʻohana ʻana o ka cellulose ether honua ma 2018 ma kahi o 1.1 miliona tons. Mai 2018 a 2023, e ulu ka hoʻohana ʻana i ka cellulose ether ma ka awelika makahiki o 2.9%.

Ma kahi kokoke i ka hapalua o ka nui o ka hoʻohana ʻana o ka cellulose ether honua he ionic cellulose (i hōʻike ʻia e CMC), ka mea i hoʻohana nui ʻia i nā detergents, oilfield additives a me nā meaʻai; ma kahi o hoʻokahi hapakolu ka non-ionic methyl cellulose a me kāna mau mea i loaʻa (e hōʻike ʻia eHPMC), a ʻo ke koena o ka hapaono he hydroxyethyl cellulose a me kāna mau mea i loaʻa a me nā etera cellulose ʻē aʻe. ʻO ka ulu ʻana o ka noi no ka non-ionic cellulose ethers e alakaʻi nui ʻia e nā noi ma nā kahua o nā mea kūkulu hale, nā uhi, nā meaʻai, nā lāʻau lapaʻau, a me nā kemika i kēlā me kēia lā. Mai ka hiʻohiʻona o ka māhele ʻāina o ka mākeke mea kūʻai aku, ʻo ka mākeke ʻAsia ka mākeke ulu wikiwiki loa. Mai 2014 a 2019, ʻo ka nui o ka ulu ʻana o ka makahiki o ka noi no cellulose ether ma Asia a hiki i 8.24%. I waena o lākou, ʻo ka noi nui ma Asia mai Kina, ʻo 23% ka nui o ka noi honua.

(2)ʻO ka ʻike o ka mākeke ether cellulose non-ionic home:

Ma Kina, ionic cellulose ethers i hōʻike ʻia eCMCi hoʻomohala mua ʻia, e hana ana i kahi kaʻina hana ʻano makua a me kahi mana hana nui. Wahi a ka ʻikepili IHS, ua noho nā mea hana Kina i ka hapalua o ka mana hana honua o nā huahana CMC kumu. Ua hoʻomaka ka hoʻomohala ʻana o ka cellulose ether non-ionic i koʻu ʻāina, akā wikiwiki ka wikiwiki.

Wahi a ka ʻikepili o China Cellulose Industry Association, ʻo ka hiki ke hana, ka hoʻopuka a me ke kūʻai aku o nā non-ionic cellulose ethers o nā ʻoihana kūloko ma Kina mai 2019 a 2021 penei:

Ma hope o nā makahiki o ka hoʻomohala ʻana, ua holomua ka mākeke non-ionic cellulose ether o Kina. I ka makahiki 2021, hiki i ka 117,600 tons ka mana hana i kūkulu ʻia no ke kūkulu ʻana i ka HPMC, ʻo 104,300 tons ka hopena, a ʻo ka nui o ke kūʻai aku he 97,500 tons. ʻO ka nui o ka ʻoihana a me ka loaʻa ʻana o nā pono kūloko i hoʻokō maoli i ka hoʻololi kūloko. Eia nō naʻe, no nā huahana HEC, ma muli o ka hoʻomaka ʻana o ka R&D a me ka hana ʻana ma koʻu ʻāina, ʻo ke kaʻina hana paʻakikī a me nā mea ʻenehana kiʻekiʻe kiʻekiʻe, ʻoi aku ka liʻiliʻi o ka mana hana o kēia manawa, ka hana a me ke kūʻai aku o nā huahana home HEC. Eia nō naʻe, i nā makahiki i hala iho nei, ke hoʻomau nei nā ʻoihana kūloko i ka hoʻonui ʻana i ka hoʻopukapuka ʻana i ka noiʻi a me ka hoʻomohala ʻana, hoʻomaikaʻi i ke kiʻekiʻe o ka ʻenehana a hoʻomohala ikaika i nā mea kūʻai aku i lalo, ua ulu wikiwiki ka hana a me ke kūʻai aku. Wahi a ka ʻikepili mai ka China Cellulose Industry Association, i ka makahiki 2021, ʻo nā ʻoihana kūloko nui HEC (i loko o nā helu helu hui ʻoihana, nā kumu āpau) i hoʻolālā ʻia he 19,000 tons, kahi huahana o 17,300 tons, a me kahi kūʻai kūʻai o 16,800 tons. Ma waena o lākou, ua hoʻonui ʻia ka mana hana e 72.73% i kēlā me kēia makahiki i hoʻohālikelike ʻia me 2020, ua hoʻonui ʻia ka huahana e 43.41% i kēlā me kēia makahiki, a ua hoʻonui ʻia ka nui o nā kūʻai aku e 40.60% i kēlā me kēia makahiki.

Ma ke ʻano he mea hoʻohui, ua hoʻopilikia nui ʻia ka nui o ke kūʻai aku ʻana o HEC e ka noi mākeke o lalo. Ma ke ʻano he kahua noi koʻikoʻi o HEC, he pilina maikaʻi ko ka ʻoihana uhi me ka ʻoihana HEC ma ke ʻano o ka hoʻopuka a me ka māhele mākeke. Mai ka manaʻo o ka hāʻawi ʻana i ka mākeke, ua māhele ʻia ka mākeke ʻoihana coatings ma Jiangsu, Zhejiang a me Shanghai ma Kina Hikina, Guangdong ma Kina Hema, ke kahakai hikina, a me Sichuan ma Southwest China. Ma waena o lākou, ʻo ka hoʻopuka ʻana o ka uhi ʻana ma Jiangsu, Zhejiang, Shanghai a me Fujian ma kahi o 32%, a ma Kina Hema a me Guangdong i helu ʻia ma kahi o 20%. 5 maluna. ʻO ka mākeke no nā huahana HEC ka mea nui i Jiangsu, Zhejiang, Shanghai, Guangdong a me Fujian. Hoʻohana nui ʻia ʻo HEC i kēia manawa i nā ʻāpana hoʻolālā, akā kūpono ia no nā ʻano uhi wai-wai e pili ana i kāna mau huahana.

I ka makahiki 2021, manaʻo ʻia ka huina makahiki o ka uhi ʻana o Kina ma kahi o 25.82 miliona mau tons, a ʻo ka hoʻopuka ʻana o nā hale kūkulu hale a me nā ʻoihana ʻenehana he 7.51 miliona tons a me 18.31 miliona mau tons. ʻO ka uhi ʻana i ka wai i kēia manawa e pili ana i ka 90% o nā uhi hale kūkulu hale, a ma kahi o 25%, ua manaʻo ʻia ʻo ka hana ʻana o ka pena wai o koʻu ʻāina ma 2021 ma kahi o 11.3365 miliona mau tona. ʻO ka manaʻo, ʻo ka nui o HEC i hoʻohui ʻia i nā pena wai wai he 0.1% a 0.5%, helu ʻia ma ka awelika o 0.3%, me ka manaʻo e hoʻohana nā pena wai a pau i ka HEC ma ke ʻano he mea hoʻohui, ʻo ke koi aupuni no ka pena-grade HEC ma kahi o 34,000 tons. Hoʻokumu ʻia i ka nui o ka hoʻoulu ʻana o ka uhi honua o 97.6 miliona tons ma 2020 (ʻo ia ka mea i hoʻopaʻa ʻia i ka hale kiʻi no 58.20% a me ka uhi ʻana o nā ʻoihana no 41.80%), ua manaʻo ʻia ka noi honua no ka coating grade HEC ma kahi o 184,000 tons.

I ka hōʻuluʻulu ʻana, i kēia manawa, ʻoi aku ka haʻahaʻa o ka mākeke o ka HEC coating grade o nā mea hana hale ma Kina, a ʻo ka māhele mākeke kūloko e noho nui ʻia e nā mea hana honua i hōʻike ʻia e Ashland o ʻAmelika Hui Pū ʻIa, a he wahi nui no ka hoʻololi home. Me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka huahana HEC home a me ka hoʻonui ʻana i ka hiki ke hana, e hoʻokūkū hou ia me nā mea hana honua ma ke kahua o lalo i hōʻike ʻia e nā uhi. ʻO ka hoʻololi ʻana i ka home a me ka hoʻokūkū mākeke honua e lilo i kumu hoʻomohala nui o kēia ʻoihana i kekahi manawa o ka wā e hiki mai ana.

Hoʻohana nui ʻia ka MHEC ma ke kahua o nā mea kūkulu hale. Hoʻohana pinepine ʻia i loko o ka momi sima e hoʻomaikaʻi ai i ka paʻa ʻana o ka wai, e hoʻolōʻihi i ka manawa hoʻonohonoho o ka mīkini sima, e hoʻemi i kona ikaika flexural a me ka ikaika compressive, a hoʻonui i kona ikaika tensile paʻa. Ma muli o ke kiko gel o kēia ʻano huahana, ʻoi aku ka liʻiliʻi o ka hoʻohana ʻana i ke kahua o nā uhi, a hoʻokūkū nui me HPMC ma ke kahua o nā mea kūkulu hale. He wahi gel ka MHEC, akā ʻoi aku ka kiʻekiʻe ma mua o HPMC, a i ka piʻi ʻana o ka ʻike o ka hydroxy ethoxy, neʻe kona wahi gel i ke ʻano o ka wela kiʻekiʻe. Inā hoʻohana ʻia i loko o ka mortar hui ʻia, ʻoi aku ka maikaʻi o ka hoʻopaneʻe ʻana i ka slurry sima ma ke ana wela Bulk electrochemical reaction, hoʻonui i ka nui o ka mālama ʻana i ka wai a me ka ikaika paʻa tensile o ka slurry a me nā hopena ʻē aʻe.

ʻO ka pālākiō hoʻolimalima o ka ʻoihana kūkulu hale, ka wahi kūkulu hale, kahi i hoʻopau ʻia, wahi hoʻonaninani hale, kahi hale hoʻoponopono hale kahiko a me kā lākou hoʻololi ʻana ke kumu nui e pili ana i ka noi no MHEC i ka mākeke kūloko. Mai ka makahiki 2021, ma muli o ka hopena o ka maʻi pneumonia lei aliʻi hou, ka hoʻoponopono ʻana i nā kulekele waiwai, a me nā pilikia wai o nā ʻoihana waiwai, ua emi ka pōmaikaʻi o ka ʻoihana waiwai o Kina, akā ʻo ka ʻoihana waiwai he ʻoihana koʻikoʻi no ka hoʻomohala waiwai o Kina. Ma lalo o nā loina holoʻokoʻa o ka "hoʻopiʻi", "kāohi i ka makemake ʻole", "hoʻokūpaʻa i nā kumukūʻai ʻāina, hoʻopaʻa i nā kumukūʻai hale, a me ka hoʻopaʻa ʻana i nā manaʻolana", e hoʻoikaika ana i ka nānā ʻana i ka hoʻoponopono ʻana i ka ʻōnaehana lako a me ka lōʻihi. ʻO ka hana hoʻokele kūpono e hōʻoia i ka hoʻomohala ʻana i ka wā lōʻihi, kūpaʻa a olakino o ka mākeke waiwai. I ka wā e hiki mai ana, ʻoi aku ka maikaʻi o ka hoʻomohala ʻana i ka ʻoihana waiwai me ka ʻoi aku ka maikaʻi a me ka wikiwiki haʻahaʻa. No laila, ʻo ka emi ʻana o ka pōmaikaʻi o ka ʻoihana waiwai i kēia manawa ke kumu o ka hoʻoponopono ʻana o ka ʻoihana i ke kaʻina o ke komo ʻana i kahi kaʻina hana hoʻomohala olakino, a ʻo ka ʻoihana waiwai ke loaʻa kahi lumi no ka hoʻomohala ʻana i ka wā e hiki mai ana. Ma ka manawa like, e like me ka "14th Five-Year Plan for National Economic and Social Development and 2035 Long-term Goal Outline", ua manaʻo ʻia e hoʻololi i ke ʻano o ke kūkulu ʻana i ke kūlanakauhale, me ka hoʻonui ʻana i ka hana hou o ke kūlanakauhale, ka hoʻololi ʻana a me ka hoʻomaikaʻi ʻana i nā kaiāulu kahiko, nā hale hana kahiko. ʻO ka piʻi ʻana o ka noi no nā mea kūkulu hale i ka hoʻoponopono hou ʻana i nā hale kahiko he kuhikuhi koʻikoʻi no ka hoʻonui ʻana o ka mākeke MHEC i ka wā e hiki mai ana.

Wahi a nā helu helu o ka China Cellulose Industry Association, mai 2019 a 2021, ʻo ka hoʻopuka ʻana o MHEC e nā ʻoihana kūloko he 34,652 tons, 34,150 tons a me 20,194 tons, a ʻo ka nui o ke kūʻai ʻana he 32,531 tons, 33,570 tons a me ka 33,570 tons. ʻO ke kumu nui ʻo iaMHECa he mau hana like ko HPMC, a hoʻohana nui ʻia no nā mea hana e like me ka mortar. Eia naʻe, ʻoi aku ka kiʻekiʻe o ke kumukūʻai a me ke kumu kūʻai o MHEC ma mua o kaHPMC. I ka pōʻaiapili o ka ulu mau ʻana o ka mana hana HPMC home, ua emi ka noi o ka mākeke no MHEC. Ma 2019 Ma 2021, ʻo ka hoʻohālikelike ma waena o ka MHEC a me ka HPMC huahana, ka nui o ke kūʻai aku, ke kumu kūʻai maʻamau, a pēlā aku.
