Kafukufuku ndi kusanthula momwe zinthu zilili panopa pakukula kwa makampani a Cellulose ether ku China. Cellulose ether ku China inayamba mochedwa, mayiko otukuka akukula msanga msika ndi wokhwima, pakadali pano, makampani odziwika padziko lonse lapansi opanga cellulose ether ndi omwe amapereka msika wapamwamba kwambiri padziko lonse lapansi, amamvetsetsa kugwiritsa ntchito ukadaulo wapamwamba, poyerekeza ndi antchito akunja omwe akuchita kafukufuku ndi kupanga cellulose ether ku China, chiwerengero cha malo osungiramo zinthu ndi akatswiri apamwamba, ali ndi kusiyana kwina mu kafukufuku ndi chitukuko ndi ukadaulo wogwiritsa ntchito.
Popeza chitetezo cha chilengedwe chikuwonjezeka komanso mfundo zokhwima za chilengedwe, zofunikira zachilengedwe zikukwera kwambiri pazida zomangira, kuphimba kwakukulu kwa chitetezo cha chilengedwe, ndi kuchuluka kwa ogula, zomwe zapangitsa kuti mapangidwe omanga nyumba apitirire mofulumira m'zaka zaposachedwa, zimalimbikitsa kukula kwa kufunika kwa msika wa cellulose ethers nthawi yomweyo, cellulose ether imapangidwa makamaka ndi ethyl cellulose, methyl cellulose, methyl cellulose, hydroxyethyl cellulose, ndi zina zotero.
Mtondo wouma wosakaniza umagwiritsa ntchito makamaka cellulose yosungunuka m'madzi, yomwe ingagawidwe m'magulu awiri: mtundu wosungunuka mwachangu ndi mtundu wosungunuka mochedwa.
Kuphatikiza apo, ether ya cellulose ingagwiritsidwe ntchito m'magawo okhudzana ndi ife, monga mabatire, mankhwala otsukira mano, sopo, kupanga mapepala, zoumbaumba, nsalu ndi zina zotero.
Malinga ndi kapangidwe ka mankhwala, zinthu zosinthira zitha kugawidwa m'magulu awiri: anionic, cationic ndi non-ionic ethers.
Etha ya cellulose yosakhala ionic imagwiritsidwa ntchito makamaka m'malo otsatirawa monga mankhwala, chakudya ndi mayeso, zokutira ndi zotsukira, mankhwala a tsiku ndi tsiku, ndi mafakitale obowola mafuta. Malinga ndi ziwerengero za deta za Chinese Cellulose Association, mu 2012, kupanga kwa etha ya cellulose yosakhala ionic ku China kunali pafupifupi matani 100,000, mpaka 2018 kupanga kwa etha ya cellulose yosakhala ionic ku China kunakula kufika matani 300,000. Pali zifukwa ziwiri zazikulu zomwe zimapangitsa kuti makampaniwa apite patsogolo mwachangu:
Kumbali imodzi, kupindula ndi chitukuko chofulumira cha kukula kwa mizinda ya m'nyumba ndi kukwezedwa kwa mfundo za dziko, kufunikira kwa msika kwa zinthu zosakhala za ionic cellulose ether kupita ku zipangizo zomangira kumawonjezeka.
Mbali ziwiri, makamaka kupanga cellulose ether palokha komanso kuchuluka kwa kafukufuku ndi chitukuko kukupitilirabe kukula, mu chakudya chamagulu ndi mankhwala ndi cellulose ether, zinthu zapakhomo pang'onopang'ono zimalowa m'malo mwa kuchuluka kwa zinthu zomwe zimatumizidwa kunja pang'onopang'ono, ndi cellulose ether kupita ku msika wotsikirapo ndikukoka kunja, mphamvu yamsika wa cellulose ether ikuyembekezeka kupitiliza kukula.
Pakadali pano, msika wa makampani a cellulose ether ku China uli wogawanika, kusiyana kwa zinthu kuli kwakukulu, mpikisano wa msika wotsika ndi waukulu kwambiri, pa chakudya ndi mankhwala ndi mitundu yapamwamba kwambiri m'malo okwera, opanga ochepa. Kodi bolodi lalifupi la makampani a cellulose ether ku China ndi makampani afupi.
Cellulose etha malinga ndi gawo logwiritsira ntchito: Gulu la chakudya ndi mankhwala ndi gulu la zipangizo zomangira ndi mankhwala a tsiku ndi tsiku, kufunika kwa msika wa zipangizo zomangira kwa etha ya cellulose ndi kwakukulu, mpaka kufunika kwa msika wonse, kuphatikizapo zomangamanga ndi zokutira ndi munda wa PVC zomwe zili ndi 80%, kuphatikizapo munda wokutira womwe uli ndi oposa 60% ya dziko lapansi, mu etha yakunja ya cellulose imagwiritsidwa ntchito kwambiri mu mankhwala a tsiku ndi tsiku ndi minda ya mankhwala ndi chakudya, chakudya ndi mankhwala ku China ndi ntchito za tsiku ndi tsiku zomwe zili ndi 11% yokha, ndi kukula kosalekeza kwa munda wogwiritsira ntchito, kufunika kwa ntchito ya etha ya cellulose m'munda kukupitirira kukula.
M'zaka zaposachedwapa, msika wa ether wa cellulose ku China ukufuna malinga ndi netiweki yayikulu ya "2019-2024 Chinese cellulose ether industry market research and competitive strategy prospect investment analysis report" deta yofufuza ndi kusanthula msika ikuwonetsa kuti mu 2012, msika wa ether wa cellulose ku China udafuna matani 336,600 mpaka theka loyamba la 2016 mpaka matani 314,600, Kufunika kwa msika pachaka ndi matani 635,100, kufunikira kwa msika mu 2019 ndi matani oposa 800,000, ndipo zikuloseredwa kuti kufunikira kwa msika mu 2020 kudzakhala matani oposa 900,000. 2019-2025 China cellulose ether market capacity compound annual growth rate kuti ipitirire kukula kwa 3%, kufunikira kwa msika kudzakulitsa madera atsopano, msika wamtsogolo udzawonetsa chizolowezi cha kukula kwapakati.
