Sodium Carboxyl methyl Cellulose (Carboxyl methyl Cellulose), yitwa CMC, ni ether ya selulose, carboxyl methyl ikomoka kuri selile, izwi kandi nka selile ya gasegereti, ni gum ya ionic selile. Yakozwe mu bucuruzi mu Burayi mu ntangiriro ya 1910 kandi ikoreshwa nka colloid na binder. Mu 1947, byari byemewe gukoreshwa nk'inyongeramusaruro mu nganda zitunganya ibiribwa kandi bigira ingaruka zikomeye. Igisubizo cyamazi ya sodium carboxymethyl selulose ifite imirimo yo kubyimba, guhuza, gushiraho firime, gufata imiti irinda, kugumana amazi, emulisiyasi no guhagarikwa, nibindi. Muri byo, CMC yo mu rwego rwa batiri ikoreshwa nk'umuhuza w'amashanyarazi ya lithium ya electrode, kandi isoko ryayo ryiyongereye cyane mu myaka yashize hamwe n'izamuka ry’inganda nshya z’imodoka mu gihugu.

Ikoranabuhanga

Umusaruro wa sodium carboxymethyl selulose urimo uburyo bwo hagati bwamazi, uburyo buke bwo gukemura, uburyo bwa slurry (uburyo bwinshi bwo gukemura) nibindi. Ibikoresho by'ibanze byingenzi bitunganijwe neza, kandi itandukaniro riri hagati yuburyo bwamazi nubwa kabiri ni uko "nta muti woguhumeka nka alcool nkibikoresho byifashishwa muburyo bwa alkalisation na etherification". Inzira ya tekiniki yuburyo bwamazi yo hagati ntabwo iri hejuru, ariko ubuziranenge nogusimbuza uburinganire bwibicuruzwa byakozwe ntabwo biri hejuru, kandi birashobora gukoreshwa gusa murwego rwo hasi rusabwa. Ibicuruzwa bifite isuku nini nabyo bigomba gutunganywa, CMC itunganijwe ifite inzitizi ndende - ishoramari ryibikoresho bigezweho kandi uburyo bwiyongera bizamura cyane igiciro, uburyo bwihuse nuburyo bwateye imbere.

Imiterere y'inganda

Ubucuruzi bwa CMC bumaze hafi imyaka ijana, ikoranabuhanga ryatunganijwe rirakuze cyane kandi nta terambere rinini ryabayeho mu myaka myinshi, ni iry'ibicuruzwa gakondo by’imiti, ntabwo bigamije kwitabwaho n’inganda nini z’imiti, umusaruro w’amahanga muri iki gihe w’inganda za CMC ufite Herklex (Ashland), amarushanwa Lu, impapuro z’Ubuyapani n’ibindi. Inganda za CMC zo mu gihugu zinjiye mu nzira yihuse y’iterambere nyuma ya 1998. By'umwihariko, mu ntangiriro z'ikinyejana cya 21, icyifuzo cya sodium carboxymethyl selulose ku masoko yo mu gihugu ndetse no ku rwego mpuzamahanga kiratera imbere, kandi impuzandengo y’ubwiyongere bw’umwaka buri mwaka ikoreshwa na CMC yo mu gihugu hagati ya 2006 na 2010 igeze kuri 17%, ibyo bikaba byabyaye umusaruro mwinshi wa karubisimethyl selulose ya sodiyumu hamwe n’ibikorwa byoroheje kandi bifite ibikoresho byinshi, kandi hari byinshi byoroshye kandi bifite ibikoresho. Itandukaniro hagati yamasosiyete nisoko rihamye ryibikoresho bihendutse bihendutse, ibiciro byangiza ibidukikije nibidukikije.

Urebye igihe cyo kwinjira mu nganda, kwinjira mu bigo byatangiye mu 1998, bikomeza kugeza mu 2016, kandi bigera ku rwego rwo hejuru muri 2014. Muri byo, 2001-2009 ni igihe cyizahabu cy’iterambere ry’inganda z’imbere mu gihugu, imishinga mishya ikomeje gushingwa, imishinga y’amahanga yinjiye. Kuva mu mwaka wa 2010 kugeza 2016, umuvuduko n'umubare w'inganda zirahinduka, haba mu gihe cyo gushora imari ndetse no mu ishoramari mu mwaka wa 2014. Mu mwaka wa 2016, nubwo ibicuruzwa byoherezwa mu gihugu bya carboxymethyl selulose n'ibicuruzwa by’umunyu byiyongereye gahoro gahoro, igiciro cyoherezwa mu mahanga cyagabanutse kugera ku mateka. Nyuma ya 2017, ishoramari mu nganda zo mu gihugu CMC ryakonje cyane, hamwe n’ibigo bibiri gusa. Tekinoroji n'ibicuruzwa byabo birarushanwa cyane. Kurugero, Hebi Fangrui Chemical yashinzwe mugukoresha ibikoresho byambere bya DuPont Danisco (Zhangjiagang) hydrophilic colloid ibikoresho bya societe hamwe nikoranabuhanga rijyanye nabakozi bakora. Fujian Meiyarui Isosiyete Nshya Yibikoresho Numusaruro gusa wa bateri yo mu bwoko bwa selulose ether yibicuruzwa, kubwa Ningde inshuro za batiri ya lithium kugirango ikore ibikoresho bifasha.

umwanzuro

1, igabanuka ryubushobozi bwinganda za sodium yo mu gihugu karboxymethyl selulose, mu buryo bufite intego kubera igabanuka ryikwirakwizwa ry’ibicuruzwa bikomoka ku isoko, nk’umusaruro w’ibiribwa mu gihugu nyuma ya 2017 ukagera mu gihe cyihuta cyo kwiyongera. Kwuzuza ibisabwa mubice gakondo bizakoreshwa mubisanzwe biganisha kumarushanwa yibiciro no gukuraho ubushobozi bwumusaruro. Kugaragara kw'ibisabwa bishya bizateza imbere imishinga mishya n'ubushobozi bushya bwo gukora, nka Fujian Meiyarui Sosiyete Nshya y'ibikoresho na Shandong Lihong Baoguan Cellulose Co., LTD., Yagura imirongo y'ibicuruzwa byo mu rwego rwa batiri. 2, icyitegererezo cyiza cyiterambere ryinganda nuburyo bukomeza ikoranabuhanga, guhora utera ibikenewe bishya, hariho itandukaniro rya tekiniki hagati yabanywanyi. Nyamara, ikibazo cyiterambere cyinganda gakondo nuko ikoranabuhanga ryibikorwa ryahagaze, ubwiyongere bwibisabwa burahagaze, kandi mugihe abanywanyi benshi bateraniye kurwego rumwe rwa tekiniki, amarushanwa yo guhuza ibitsina arafungura. Mugihe ibintu byikoranabuhanga bidashobora gusubirwamo, ibindi bintu byo kwisoko bigomba gushingwa. 3. Gusubiramo ibindi bintu byamasoko, nkibintu byingenzi, umurimo, ubutaka n’ibidukikije, bishingiye ku kuboko kutagaragara kw isoko igihe kirekire, kandi bigomba gushingira ku kiganza kigaragara cya politiki: imiyoborere y’ibidukikije; Igipimo cyo kugabanya imisoro yoherezwa mu mahanga; Kunoza ubuziranenge bwibicuruzwa; Kuzamura urwego rwinjira mubushobozi bushya bwo gukora.
