Cellulose etherni ijambo rusange ryibikomoka kubintu bitandukanye byakuwe muri selile karemano (ipamba itunganijwe neza hamwe nimbuto zimbaho, nibindi) Ibicuruzwa bivamo nibikomoka kumasoko ya selile. Nyuma ya etherification, selile irashobora gushonga mumazi, igabanya umuti wa alkali hamwe na solge organic, kandi ifite thermoplastique. Hariho ubwoko bwinshi bwa selile ya selile, ikoreshwa cyane mubwubatsi, sima, irangi, ubuvuzi, ibiryo, peteroli, imiti ya buri munsi, imyenda, gukora impapuro nibikoresho bya elegitoronike nizindi nganda. Ukurikije umubare wabasimbuye, irashobora kugabanywa muri ether imwe hamwe na ether ivanze, kandi ukurikije ionisiyoneri, irashobora kugabanywamo ionic selulose ether na ether ionic selulose ether. Kugeza ubu, ionic selulose ether ionic ibicuruzwa bifite tekinoroji yumusaruro ukuze, gutegura byoroshye, igiciro gito ugereranije, hamwe nimbogamizi zinganda. Zikoreshwa cyane cyane mubyongeweho ibiryo, abafasha imyenda, imiti ya buri munsi nizindi nzego, kandi nibicuruzwa byingenzi kumasoko.
Kugeza ubu, isi yingenzi ya selile ethers niCMC, HPMC, MC, HEC, n'ibindi Muri byo, CMC ifite umusaruro mwinshi, ihwanye na kimwe cya kabiri cy’ibicuruzwa biva ku isi, mu gihe HPMC na MC bingana na 33% by’ibikenewe ku isi, kandiHECbingana na 50% by'ibikenewe ku isi. 13% by'isoko. Imikoreshereze yingenzi ikoreshwa rya carboxymethyl selulose (CMC) ni ibintu byangiza, bingana na 22% by isoko ryo hasi, kandi nibindi bicuruzwa bikoreshwa cyane mubikoresho byubaka, ibiryo nubuvuzi.
Porogaramu yo hasi
Mu bihe byashize, kubera iterambere rike ry’igihugu cyanjye gikenera selile ya selile mu bijyanye n’imiti ya buri munsi, ubuvuzi, ibiryo, ibifuniko, n'ibindi, icyifuzo cya selile ya selile mu Bushinwa cyari cyibanze cyane mu bijyanye n’ibikoresho byo kubaka. Kugeza uyu munsi, inganda zubaka ziracyafite 33% byigihugu cya selulose ether. Icyifuzo cya selile yigihugu cyanjye mubijyanye nibikoresho byubwubatsi cyujujwe, kandi ibisabwa mubijyanye n’imiti ya buri munsi, ubuvuzi, ibiryo, ibifuniko, nibindi biriyongera cyane hamwe niterambere ryikoranabuhanga. Kurugero, mumyaka yashize, capsules yimboga hamwe na selile ya selile nkibikoresho fatizo byingenzi, hamwe ninyama zubukorikori, ibicuruzwa bivuka bikozwe na selile ya ether, bifite ibyifuzo byinshi kandi byikura.
Dufashe umurima wibikoresho byubwubatsi nkurugero, selile ya selile ifite ibintu byiza cyane nko kubyimba, kubika amazi, no kudindiza. Kubwibyo, kubaka ibikoresho bya selile ya selile ikoreshwa cyane mugutezimbere umusaruro wa minisiteri ivanze (harimo minisiteri ivanze na minisiteri yumye), PVC resin, nibindi, irangi rya latex, putty, nibindi, harimo no gukora kubaka ibikoresho. Bitewe n’iterambere ry’igihugu cyanjye mu mijyi, iterambere ryihuse ry’inganda zubaka, gukomeza kunoza urwego rw’imashini zubaka, hamwe n’ibisabwa byiyongera ku bidukikije ku baguzi ku bikoresho by’ubwubatsi byatumye hakenerwa ether ya selile idafite ionic. mu rwego rwo kubaka ibikoresho. Mu gihe cy’imyaka 13 y’imyaka itanu, igihugu cyanjye cyihutishije guhindura imidugudu y’imijyi n’amazu yangiritse, kandi ishimangira iyubakwa ry’ibikorwa remezo byo mu mijyi, harimo kwihutisha ihinduka ry’imijyi ituwe cyane n’imidugudu yo mu mijyi, iteza imbere ivugurura ryuzuye ry’imiturire ishaje, amazu yashaje yangiritse hamwe nudusanduku tutuzuye Amazu avugurura nibindi. Mu gice cya mbere cya 2021, ubuso bw’inyubako nshya zo guturamo zo mu ngo zari miliyoni kare 755.15, ziyongereyeho 5.5%. Ubuso bwuzuye bwamazu bwari metero kare 364.81, bwiyongereyeho 25.7%. Kugarura agace kuzuye k'umutungo utimukanwa bizatera ibyifuzo bijyanye murwego rwa selile yubaka selile.
Uburyo bwo guhatanira isoko
Igihugu cyanjye nikintu kinini gitanga selile ether kwisi. Kuri iki cyiciro, ibikoresho byo murugo ibikoresho bya selile ether ahanini byegereye. Shandong Heda n’umushinga wambere mu bijyanye na selulose ether mu Bushinwa. Abandi bakora inganda zikomeye mu gihugu barimo Shandong Ruitai, Shandong Yiteng, na Chemical Tianpu y'Amajyaruguru, Yicheng Cellulose, n’ibindi. Lotte. Usibye Shandong Heda hamwe nandi masosiyete afite ubushobozi bwa toni zirenga 10,000, hari ninganda nyinshi zikora za ether selile selile zidafite ubushobozi bwa toni 1.000. Ibiribwa byo mu rwego rwo hejuru nibicuruzwa byo mu rwego rwa farumasi.
Kuzana no kohereza hanze ya selile ether
Muri 2020, kubera igabanuka ry’ubushobozi bw’umusaruro w’amasosiyete y’amahanga kubera icyorezo cyo mu mahanga, ubwinshi bw’ibicuruzwa byoherezwa mu mahanga bya selile mu gihugu cyanjye byagaragaje iterambere ryihuse. Muri 2020, kohereza hanze ya selile ya selile bizagera kuri toni 77.272. Nubwo ibicuruzwa byoherezwa mu mahanga byigihugu cyanjyeselile etheryazamutse vuba, ibicuruzwa byoherezwa mu mahanga byubaka cyane ibikoresho bya selile ya selile, mu gihe ibicuruzwa byoherezwa mu mahanga byo mu rwego rw’ubuvuzi n’ibiribwa selulose ether ari bike cyane, kandi agaciro kiyongereye ku bicuruzwa byoherezwa mu mahanga ni bike. Kugeza ubu, ibicuruzwa byoherezwa mu mahanga mu gihugu cya selulose ether bikubye inshuro enye ibicuruzwa biva mu mahanga, ariko agaciro ko kohereza mu mahanga kari munsi yikubye kabiri agaciro kinjira mu mahanga. Mu rwego rwibicuruzwa byo mu rwego rwo hejuru, gahunda yo gusimbuza ibyoherezwa mu mahanga ya selile yo mu gihugu iracyafite ibyumba byinshi byiterambere.
