Pehea ka ulu ʻana o ka cellulose ether honua?

Wahi a ka hōʻike hou loa mai IHS Markit, ka ʻai honua ocellulose etera—he polymer hiki ke hoʻoheheʻe wai i hana ʻia e ka hoʻololi kemika o cellulose-ua kokoke i 1.1 miliona tons ma 2018. ʻO ka nui o ka honua cellulose ether production i 2018, 43% mai Asia (ʻo Kina ka 79% o ka hana ʻana o ʻAsia), Western Europe i 36%, a ʻo ʻAmelika ʻĀkau he 8%. Wahi a IHS Markit, ua manaʻo ʻia e ulu ka hoʻohana ʻana i ka cellulose ether ma ka awelika makahiki o 2.9% mai 2018 a 2023. I loko o kēia manawa, ʻoi aku ka haʻahaʻa o ka ulu ʻana o ka noi ma nā mākeke makua ma ʻAmelika ʻAmelika a me ʻEulopa ma mua o ka awelika honua, 1,2% a me 1,3%. , oiai ka ulu ana o ka noi ma Asia a me Oceania e oi aku mamua o ka awelika honua, ma 3.8%; ʻO ka ulu nui o ka noi ma Kina e 3.4%, a ʻo ka ulu ʻana ma Central a me ʻEulopa ʻEulopa e manaʻo ʻia he 3,8%.

Ma 2018, ʻo ka ʻāina me ka nui o ka hoʻohana ʻana i ka cellulose ether ma ka honua ʻo ʻAsia, ʻo ia ka 40% o ka nui o ka hoʻohana ʻana, a ʻo Kina ka mea hoʻokele nui. ʻO ʻEulopa Komohana a me ʻAmelika ʻĀkau he 19% a me 11% o ka hoʻohana honua, kēlā me kēia.Carboxymethyl cellulose (CMC)ʻO ka 50% o ka nui o ka hoʻohana ʻana i nā cellulose ethers ma 2018, akā ʻo ka nui o ka ulu ʻana e manaʻo ʻia e haʻahaʻa ma mua o ka cellulose ethers holoʻokoʻa i ka wā e hiki mai ana.Methylcellulose(MC) hydroxypropyl methyl cellulose (HPMC)he 33% o ka huina hoohana,hydroxyethyl cellulose (HEC)ʻO 13%, a ʻo nā ether cellulose ʻē aʻe ma kahi o 3%.

Wahi a ka hōʻike, hoʻohana nui ʻia nā cellulose ethers i nā mānoanoa, adhesives, emulsifiers, humectants, a me nā mea hoʻomalu viscosity. ʻO nā palapala hoʻopau e pili ana i nā mea hoʻopaʻa a me nā grouts, nā meaʻai, nā pena a me nā uhi, a me nā lāʻau lapaʻau a me nā meaʻai meaʻai. ʻO nā ʻano cellulose ethers e hoʻokūkū pū kekahi me kekahi i nā mākeke noiʻi he nui, a me nā huahana ʻē aʻe me nā hana like, e like me nā polymers wai-soluble synthetic a me nā polymers wai-soluble maoli. ʻO nā polymers hiki ke hoʻoheheʻe ʻia i ka wai me nā polyacrylates, nā polyvinyl alcohols, a me nā polyurethanes, aʻo nā polymers hiki ke hoʻoheheʻe ʻia i ka wai maoli ka nui o ka xanthan gum, carrageenan, a me nā gums ʻē aʻe. Ma kahi noi kikoʻī, ʻo ka polymer e koho hope ai ka mea kūʻai aku ma muli o ke kālepa-off ma waena o ka loaʻa, ka hana a me ke kumukūʻai, a me ka hopena o ka hoʻohana.

I ka makahiki 2018, ua hiki i ka mākeke carboxymethylcellulose (CMC) honua holoʻokoʻa i 530,000 tons, hiki ke hoʻokaʻawale ʻia i loko o ka pae ʻenehana (stock solution), semi-purified grade a me ka kiʻekiʻe maʻemaʻe kiʻekiʻe. ʻO ka hoʻohana hope nui loa o ka CMC he mea holoi, me ka hoʻohana ʻana i ka papa hana CMC, e helu ana ma kahi o 22% o ka hoʻohana ʻana; aila palapala noi helu no ma kahi o 20%; ʻO nā mea hoʻohui meaʻai ma kahi o 13%. Ma nā ʻāpana he nui, ʻoi aku ka nui o nā mākeke mua o CMC, akā ʻo ka noi mai ka ʻoihana ʻaila he mea maʻalahi a pili i nā kumukūʻai aila. Ke kū nei ʻo CMC i ka hoʻokūkū mai nā huahana ʻē aʻe, e like me ka hydrocolloids, hiki ke hāʻawi i ka hana ʻoi aku ka maikaʻi ma kekahi mau noi. ʻO ka noi no nā cellulose ethers ʻē aʻe ma mua o CMC e alakaʻi ʻia e ka hoʻohana hope ʻana, me ka uhi ʻana o ka ʻili, a me nā meaʻai, nā lāʻau lapaʻau a me nā noi mālama pilikino, wahi a IHS Markit.

Wahi a ka hōʻike ʻo IHS Markit, ʻo ka mākeke ʻoihana CMC e ʻokiʻoki mau ana, me nā mea hana ʻelima nui loa e helu wale ana no 22% o ka nui o ka nui. I kēia manawa, ʻoi aku ka nui o nā mea hana CMC ʻoihana Kina i ka mākeke, e helu ana no 48% o ka nui o ka hiki. ʻO ka hana ʻana o ka mākeke CMC hoʻomaʻemaʻe maʻemaʻe i koʻikoʻi, a ʻo nā mea hana ʻelima nui loa he 53%.

ʻOkoʻa ka ʻāina hoʻokūkū o CMC mai nā cellulose ethers ʻē aʻe. He haʻahaʻa haʻahaʻa ka paepae, ʻoi aku hoʻi no nā huahana CMC ʻenehana me ka maʻemaʻe o 65% ~ 74%. ʻO ka mākeke no ia mau huahana ʻoi aku ka ʻāpana a hoʻomalu ʻia e nā mea hana Kina. ʻO ka mākeke no ka papa hoʻomaʻemaʻeCMCʻoi aku ka paʻa, nona ka maʻemaʻe o 96% a ʻoi paha. I ka makahiki 2018, ʻo ka hoʻohana honua ʻana i nā cellulose ethers ʻē aʻe ma mua o CMC he 537,000 tons, i hoʻohana nui ʻia i nā ʻoihana e pili ana i ke kūkulu ʻana, ʻo 47%; ʻO nā noi ʻoihana meaʻai a me nā lāʻau lapaʻau he 14%; ʻO 12% ka ʻoihana uhi uhi. ʻOi aku ka nui o ka mākeke no nā cellulose ethers, me nā mea hana ʻelima kiʻekiʻe e helu ana no 57% o ka mana hana honua.

Ma ke ʻano holoʻokoʻa, e hoʻomau nā manaʻo noi o cellulose ethers i ka ʻoihana meaʻai a me ka mālama pilikino i kahi ulu ulu. E like me ka makemake o nā mea kūʻai aku no nā huahana meaʻai olakino me ka momona haʻahaʻa a me ke kō e hoʻomau i ka ulu ʻana, i mea e pale aku ai i nā allergens e like me ka gluten, a laila e hāʻawi ana i nā manawa mākeke no nā cellulose ethers, hiki ke hāʻawi i nā hana i koi ʻia, me ka ʻole o ka ʻono a me ke ʻano. I kekahi mau noi, ke alo nei ka cellulose ethers i ka hoʻokūkū mai nā mānoanoa i loaʻa mai i ka fermentation, e like me nā ʻāʻī maoli.
