ʻO ka hui ʻo Kima ka hale hana ʻoihana cellulose ether ma Kina. Hoʻopuka ia i nā māka like ʻole o ka cellulose ether a me ka cellulose ether i hoʻololi ʻia.
Cellulose Eteraa me kāna mau mea kūʻai mai ka wanana mākeke ma 2022:
I ka makahiki 2021, ʻo ka ʻai honua o cellulose ethers, nā polymers wai-soluble i hana ʻia e ka hoʻololi kemika o cellulose, kokoke i 1.1 miliona tons. ʻO ka nui o ka hana cellulose ether honua i ka makahiki 2021, 43% mai Asia mai (ʻo Kina ka 79% o ka hana ʻana o ʻAsia), ʻo ʻEulopa ʻEulopa he 36%, a ʻo ʻAmelika ʻĀkau he 8%. ʻO ka hoʻohana ʻana i nā cellulose ethers e manaʻo ʻia e ulu i ka awelika makahiki o 2.9% mai 2021 a 2023, me ka ulu ʻana o ka noi i nā mākeke makua ma ʻAmelika ʻAmelika a me ʻEulopa ma ke ʻano he haʻahaʻa ma mua o ka awelika o ka honua, ma 1.2% a me 1.3%. , oiai e oi aku ka nui o ka nui o ka noi ma Asia a me Oceania ma mua o ka awelika honua, ma 3.8%; ʻO 3.4% ka nui o ka koi ʻana o Kina, a ʻo ka ulu ʻana ma Central a me ʻEulopa ʻEulopa e manaʻo ʻia he 3,8%.
ʻO ka ʻāina me ka nui loa o ka cellulose ether ma ka honua i 2022 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. ʻO Carboxymethyl cellulose (CMC) i helu ʻia no 50% o ka nui o ka hoʻohana ʻana i nā cellulose ethers i 2022, akā manaʻo ʻia ka haʻahaʻa o kona ulu ʻana ma mua o ka cellulose ethers holoʻokoʻa i ka wā e hiki mai ana. Methyl cellulose/hydroxypropyl methyl cellulose (MC/HPMC) i helu ʻia no 33% o ka nui o ka hoʻohana ʻana, hydroxyethyl cellulose (HEC) helu no 13%, a me nā cellulose etera ʻē aʻe ma kahi o 3%.
Hoʻohana nui ʻia nā cellulose ethers e like me nā mānoanoa, binders, emulsifiers, humectants a me nā mea hoʻokele viscosity. Loaʻa nā mea hoʻopau i nā sealants a me nā grouts, nā huahana 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 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. ʻO ka koho hope loa o ka polymer no kahi noi kikoʻī e hilinaʻi ʻia ma ke kālepa-off ma waena o ka loaʻa, ka hana a me ke kumukūʻai, a me ka pono o ka hoʻohana.
I ka makahiki 2022, ua hōʻea ka mākeke carboxymethyl cellulose (CMC) honua i 530,000 tons, hiki ke hoʻokaʻawale ʻia i loko o ka pae ʻenehana (stock solution), semi-purified grade a me ka kiʻekiʻe maʻemaʻe. ʻO ka hoʻohana hope nui loa o ka CMC he mea hoʻomaʻemaʻe, e hoʻohana ana i ka CMC papa hana ʻoihana, ʻo ia ka mea ma kahi o 22% o ka hoʻohana ʻana; ʻO nā noi kahua aila no kahi o 20%; a me nā mea hoʻohui meaʻai ma kahi o 13%. Ma nā ʻāpana he nui, ʻoi aku ka nui o nā mākeke koʻikoʻi o CMC, akā ʻo ka noi mai ka ʻoihana ʻaila ʻoi aku ka liʻiliʻi a pili i nā kumukūʻai aila. Ke alo 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 o ke kūkulu ʻana, me ka uhi ʻana o ka ʻili, a me nā meaʻai, lāʻau lapaʻau a me nā noi mālama pilikino.
ʻO ka mākeke ʻoihana ʻo CMC ka mea i hoʻokaʻawale ʻia, me nā mea hana 5 kiʻekiʻe he 22% wale nō o ka nui o ka hiki. I kēia manawa, ʻoi aku ka nui o nā mea hana CMC kiʻekiʻe Kina i ka mākeke, e helu ana no 48% o ka nui o ka hiki. ʻO ka mākeke CMC maʻemaʻe maʻemaʻe i koʻikoʻi i ka hana ʻana, me nā mea hana ʻelima kiʻekiʻe e loaʻa i ka 53% o ka mana hana.
ʻOkoʻa ka ʻāina hoʻokūkū o CMC me nā mea ʻē aʻe o nā cellulose ethers, me nā pale haʻahaʻa haʻahaʻa i ke komo ʻana, ʻoi aku hoʻi no nā huahana CMC ʻenehana me ka maʻemaʻe o 65% a 74%. ʻO ka mākeke no ia mau huahana ʻoi aku ka ʻāpana a hoʻomalu ʻia e nā mea hana Kina. ʻOi aku ka nui o ka mākeke CMC maʻemaʻe, me ka maʻemaʻe o 96% a i ʻole. I ka makahiki 2022, he 537,000 tons ka nui o ka hoʻohana ʻana i nā cellulose ethers ʻē aʻe ma mua o CMC, a ʻo nā noi nui he mau noi hana e pili ana i ke kūkulu ʻana, e helu ana no 47%; ʻO nā noi ʻoihana meaʻai a me nā lāʻau lapaʻau he 14%; ʻO 12% ka ʻoihana uhi uhi. ʻOi aku ka nui o nā mākeke cellulose ether, me nā mea hana 5 kiʻekiʻe e helu pū ana no 57% o ka mana 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 ka poʻe kūʻai no nā 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), e loaʻa nā manawa mākeke no nā cellulose ethers, hiki ke hāʻawi i ka hana i makemake ʻia, ʻaʻole hoʻi e hoʻololi i ka ʻono. a i ʻole 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.
