Ụlọ ọrụ Kima bụ ọkachamara cellulose ether factory na China. Ọ na-emepụta ọkwa dị iche iche nke cellulose ether na cellulose ether gbanwetụrụ.
Cellulose ether& Amụma Ahịa nke mmepụta ya na 2022:
Na 2021, oriri zuru ụwa ọnụ nke cellulose ethers, polymers soluble mmiri emepụtara site na mgbanwe kemịkalụ nke cellulose, dị nso 1.1 nde tọn. N'ime mkpokọta cellulose ether zuru ụwa ọnụ na 2021, 43% sitere na Eshia (China nwetara 79% nke mmepụta Eshia), Western Europe ruru 36%, na North America nwetara 8%. A na-atụ anya na oriri cellulose ethers ga-eto na nkezi kwa afọ nke 2.9% site na 2021 ruo 2023, na-eto eto na ahịa tozuru oke na North America na Western Europe na-adị ala karịa nkezi ụwa, na 1.2% na 1.3%, n'otu n'otu. , ebe ọnụ ọgụgụ uto nke Asia na Oceania ga-adị elu karịa nkezi zuru ụwa ọnụ, na 3.8%; Ọnụ ọgụgụ ndị China chọrọ bụ 3.4%, na ọnụ ọgụgụ uto na Central na Eastern Europe ga-abụ 3.8%.
Mpaghara nwere nnukwu oriri nke cellulose ether n'ụwa na 2022 bụ Eshia, na-aza 40% nke mkpokọta oriri, na China bụ isi ihe na-anya ụgbọ ala. Western Europe na North America bụ 19% na 11% nke oriri zuru ụwa ọnụ, n'otu n'otu. Carboxymethyl cellulose (CMC) nwetara 50% nke mkpokọta cellulose ethers na 2022, mana a na-atụ anya na uto ya ga-adị ala karịa nke cellulose ethers n'ozuzu ya n'ọdịnihu. Methyl cellulose/hydroxypropyl methyl cellulose (MC/HPMC) nwetara 33% nke ngụkọta oriri, hydroxyethyl cellulose (HEC) ruru 13%, na ndị ọzọ cellulose ethers ruru ihe dị ka 3%.
A na-ejikarị ethers cellulose eme ihe dị ka ndị na-ebu ibu, ndị na-ekekọta, emulsifiers, humectants na viscosity control agents. Ngwa ngwụcha na-agụnye akara na grouts, ngwaahịa nri, agba na mkpuchi, yana ọgwụ ndenye ọgwụ na mgbakwunye nri. Ethers cellulose dị iche iche na-asọrịta mpi n'ọtụtụ ahịa ngwa yana ngwaahịa ndị ọzọ nwere ọrụ ndị yiri ya, dị ka polymers mmiri na-eme ka mmiri na-emepụta ihe na polymers mmiri na-edozi mmiri. Ihe ndị na-eme ka mmiri na-eme ka mmiri sịntetik na-agụnye polyacrylates, polyvinyl alcohols, na polyurethanes, ebe ndị na-emepụta mmiri na-emepụta mmiri na-agụnyekarị xanthan gum, carrageenan, na chịngọm ndị ọzọ.

Na 2022, ngụkọta zuru ụwa ọnụ ahịa carboxymethyl cellulose (CMC) ruru 530,000 ton, nke nwere ike kewaa n'ime ụlọ ọrụ ọkwa (ngwaahịa ngwọta), ọkara-ọcha ọkwa na elu-ọcha ọkwa. Ihe njedebe kachasị mkpa nke CMC bụ nchacha, nke na-eji ọkwa mmepụta ihe CMC, nke na-eme ihe dịka 22% nke oriri; Ngwa mmanụ mmanụ na-eme ihe dịka 20%; na ihe mgbakwunye nri bụ ihe dịka 13%. N'ọtụtụ mpaghara, isi ahịa CMC tozuru oke, mana ọchịchọ sitere na ụlọ ọrụ na-ahụ maka mmanụ na-agbanwe agbanwe ma jikọta ya na ọnụ ahịa mmanụ. CMC na-echekwa asọmpi sitere na ngwaahịa ndị ọzọ, dị ka hydrocolloids nke nwere ike inye arụmọrụ dị elu na ngwa ụfọdụ. Achọ maka cellulose ethers ndị ọzọ na-abụghị CMC ga-akpali site na njedebe ihe owuwu, gụnyere mkpuchi elu, yana nri, ọgwụ na ngwa nlekọta onwe onye.
Ahịa ụlọ ọrụ CMC ka na-ekewa ekewa, yana ndị na-emepụta 5 kachasị elu na-aza naanị 22% nke ikike niile. Ugbu a, ndị China na-emepụta ọkwa CMC na-achịkwa ahịa, na-aza 48% nke ikike niile. Ahịa CMC dị ọcha na-elekwasị anya na mmepụta, yana ndị nrụpụta ise kachasị elu nwere 53% nke ikike mmepụta.
Okirikiri asọmpi nke CMC dị iche na nke cellulose ethers ndị ọzọ, na-enwe ihe mgbochi dị ala maka ịbanye, karịsịa maka ngwaahịa CMC nke ụlọ ọrụ mmepụta ihe na ịdị ọcha nke 65% ruo 74%. Ahịa maka ngwaahịa ndị dị otú ahụ na-ekewa ma na-achịkwa ndị na-emepụta China. Ahịa CMC dị ọcha na-etinyekwu uche karị, yana ịdị ọcha nke 96% ma ọ bụ karịa. Na 2022, oriri zuru ụwa ọnụ nke cellulose ethers na-abụghị CMC bụ 537,000 tọn, na ngwa ndị bụ isi bụ ngwa ụlọ ọrụ metụtara ihe owuwu, na-aza 47%; ngwa nri na ụlọ ọrụ ọgwụ bụ 14%; Ụlọ ọrụ mkpuchi elu bụ 12%. Ahịa cellulose ether ọzọ na-etinyekwu uche karị, yana ndị na-emepụta 5 kachasị elu na-agbakọ ọnụ maka 57% nke ikike zuru ụwa ọnụ.
