Kafukufuku ndi kusanthula mmene zinthu zilili panopa chitukuko cha Ma cellulose etere makampani China.Cellulose etere ku China anayamba mochedwa, mayiko otukuka kukhala msika oyambirira ndi okhwima, panopa, mayiko odziwika bwino mapadi etere kupanga mabizinesi ndi zikuluzikulu padziko lonse mkulu- mapeto a msika, kumvetsa kugwiritsa ntchito zipangizo zamakono, poyerekeza ndi ogwira ntchito yachilendo chinkhoswe mu kafukufuku ndi kupanga mapadi etero ku China, chiwerengero cha nkhokwe ndi mkulu mlingo akatswiri, ali ndi kusiyana kwina mu kafukufuku ndi chitukuko ndi ntchito luso.
Monga kukulitsa chidziwitso cha chitetezo cha chilengedwe ndi malamulo okhwima a chilengedwe, zofunikira zachilengedwe zimakwera ndikukwera kwa zida zomangira, kuphimba kwakukulu kwa chitetezo cha chilengedwe, ndi kuchuluka kwa ogula, zomwe zidapangitsa kukula mwachangu kwa zokutira zomanga m'zaka zaposachedwa, kumalimbikitsa kukula kwa ma cellulose ethers. Kufunika kwa msika nthawi yomweyo, ether ya cellulose imapangidwa makamaka ndi cellulose ethyl, methyl cellulose, methyl cellulose, hydroxyethyl cellulose, etc.
Dongo lowuma losakanizika makamaka limagwiritsa ntchito mapadi osungunuka m'madzi, omwe amatha kugawidwa m'mitundu yosungunuka mwachangu komanso mtundu wosungunuka wochedwa.
Kuphatikiza apo, ether ya cellulose ingagwiritsidwe ntchito m'minda yomwe ikugwirizana kwambiri ndi ife, monga mabatire, mankhwala otsukira mano, zotsukira, zopangira mapepala, zoumba, nsalu ndi zina zotero.
Malinga ndi kapangidwe ka mankhwala gulu la m'malo, akhoza kugawidwa mu anionic, cationic ndi non-ionic ethers.
Non-ionic cellulose ether imagwiritsidwa ntchito makamaka kunsi kwa mankhwala, chakudya ndi kuyesa, zokutira ndi zotsukira, mankhwala a tsiku ndi tsiku, mafakitale obowola mafuta.Malinga ndi Chinese Cellulose Association deta ziwerengero, mu 2012, China sanali ionic mapadi efa kupanga pafupifupi 100,000 matani, kuti 2018 China sanali ionic mapadi efa kupanga anakula kwa matani 300,000.Pali zifukwa ziwiri zazikuluzikulu zakukula mwachangu kwamakampani:
Kumbali imodzi, kupindula ndi kupititsa patsogolo chitukuko cha anthu akumidzi komanso kupititsa patsogolo ndondomeko za dziko, kufunikira kwa msika wa ether osakhala ionic cellulose kuzinthu zomangira kalasi kumawonjezeka.
mbali ziwiri, makamaka mapalulo etere kupanga palokha ndi kafukufuku ndi chitukuko mlingo akupitiriza bwino, mu kalasi chakudya ndi mankhwala ndi mapadi etero zoweta katundu pang'onopang'ono m'malo gawo la imports pang'onopang'ono kuchuluka, ndi mapadi etero ku malowedwe msika kumtunda ndi kukoka katundu, tsogolo. Msika wa cellulose ether ukuyembekezeka kupitiliza kukula.
Pakalipano, chitsanzo cha msika wa msika wa cellulose ether wa China wamwazikana, kusiyana kwa mankhwala ndi kwakukulu, mpikisano wa msika wotsika kwambiri umakhala wovuta kwambiri, chifukwa cha zakudya ndi mankhwala ndi mitundu yapamwamba kupita kumalo apamwamba, opanga ochepa.Ndi gulu lalifupi lamakampani aku China a cellulose ether.
Ma cellulose ether malinga ndi gawo la ntchito: kalasi yazakudya ndi kalasi yamankhwala ndi zida zomangira kalasi ndi mankhwala atsiku ndi tsiku, msika wazinthu zomangira msika wa cellulose ether ndi wawukulu, mpaka kufunika kwa msika wonse, kuphatikiza zomangamanga ndi zokutira ndi gawo la PVC lowerengera 80. %, kuphatikizapo ❖ kuyanika munda amawerengera oposa 60% ya dziko, mu yachilendo mapadi efa chimagwiritsidwa ntchito tsiku ndi tsiku mankhwala ndi mankhwala ndi chakudya minda, chakudya China ndi mankhwala ndi ntchito mankhwala tsiku ndi tsiku ndi 11% okha, ndi kukula mosalekeza wa m'munda ntchito, kufunika kwa cellulose ether ntchito m'munda akupitiriza kukula.
M'zaka zaposachedwapa, China mapalo efa msika ankafuna malinga ndi pachimake maukonde "2019-2024 Chinese mapadi eteri msika kafukufuku ndi mpikisano njira chiyembekezo kusanthula lipoti" msika kafukufuku ndi kusanthula deta zikusonyeza kuti mu 2012, China mapalo efa kutsika msika amafuna 336,600. matani kuti theka loyamba la 2016 mapadi efa amafuna matani 314,600, Kufuna msika pachaka ndi matani 635,100, kufunika msika mu 2019 ndi oposa 800.000 matani, ndipo ananeneratu kuti kufunika msika mu 2020 adzakhala oposa 900,000 matani. .2019-2025 China cellulose ether msika mphamvu pawiri pachaka kukula kwa 3% kukula, kufunikira kwa msika kukulitsa madera atsopano, msika wamtsogolo uwonetsa mayendedwe a liwiro lapakati pakukula.
