Sodium Carboxyl methyl Cellulose (Carboxyl methyl Cellulose), yotchedwa CMC, ndi cellulose ether, carboxyl methyl yochokera ku cellulose, yomwe imadziwikanso kuti cellulose chingamu, ndiye chingamu chofunikira kwambiri cha ionic cellulose. Idapangidwa ku Europe koyambirira kwa 1910s ndipo idagwiritsidwa ntchito ngati colloid ndi binder. Mu 1947, idaloledwa kugwiritsidwa ntchito ngati chowonjezera pamakampani opanga zakudya ndipo imakhala ndi mphamvu yokulirakulira. The amadzimadzi njira ya sodium carboxymethyl mapadi ali ndi ntchito za thickening, kugwirizana, filimu mapangidwe, zomatira zoteteza, chinyezi posungira, emulsification ndi kuyimitsidwa, etc. mankhwala ambiri ndi mafuta kalasi, chakudya kalasi, tsiku mankhwala kalasi, kalasi mankhwala ndi batire kalasi CMC. Pakati pawo, CMC ya batire ya batire imagwiritsidwa ntchito ngati chomangira ma sheet a electrode a lithiamu batire, ndipo kufunikira kwake pamsika kwakula kwambiri m'zaka zaposachedwa ndi kukwera kwamakampani opanga magalimoto atsopano.

Njira zamakono

Njira yopangira sodium carboxymethyl cellulose imaphatikizapo njira yapakati pamadzi, njira yosungunulira yotsika, njira ya slurry (njira zingapo zosungunulira) ndi zina zotero. The kiyi zopangira ndi woyengedwa mapadi, ndi kusiyana pakati pa njira amadzimadzi ndi awiri otsiriza ndi kuti "palibe zosungunulira organic monga mowa monga sing'anga anachita mu ndondomeko ya alkalization ndi etherification". Njira yaukadaulo ya njira ya sing'anga yamadzi siili yokwera, koma chiyero ndi kufanana kwazinthu zomwe zimapangidwira sizokwera kwambiri, ndipo zitha kugwiritsidwa ntchito kumunda wofunikira kwambiri. Zogulitsa zoyera kwambiri zimafunikanso kuyeretsedwa, CMC yoyengedwa ili ndi chotchinga chachikulu - kuyika zida zapamwamba komanso njira yowonjezereka idzakweza mtengowo, njira ya slurry ndi njira yotsogola kwambiri.

Mkhalidwe wamakampani

CMC malonda wakhala pafupifupi zaka zana, ndondomeko luso ndi okhwima kwambiri ndipo palibe yotulukira lalikulu kwa zaka zambiri, ndi wa mankhwala chikhalidwe mankhwala, osati tcheru mabizinezi lalikulu mankhwala, panopa akunja kupanga CMC mabizinesi ali Herklex (Ashland), mpikisano Lu, Japan pepala ndi zina zotero. The zoweta CMC makampani analowa mu njanji yachangu ya chitukuko pambuyo 1998. Makamaka, kumayambiriro kwa zaka za m'ma 21, kufunika sodium carboxymethyl mapadi m'misika zoweta ndi mayiko zikuyenda bwino, ndipo pafupifupi pachaka kukula kwa mowa CMC zoweta pakati 2006 ndi 2010 wafika 17%, amene spawned ambiri osavuta ndi sodium carboxymethyl mapadi ndi zipangizo ndi ma cellulose opangidwa ndi sodium carboxyprise ndi ma cellulose. pachimake, njira zawo ndi zofanana. Kusiyana pakati pamakampani ndikukhazikika kwazinthu zotsika mtengo, ndalama zogwiritsira ntchito zachilengedwe komanso mtundu wazinthu.

Kuchokera pamalingaliro a nthawi yolowera makampani, kulowa kwamakampani kudayamba mu 1998, kupitilira mpaka 2016, ndipo adafika pachimake mu 2014. Pakati pawo, 2001-2009 ndi nthawi yagolide ya chitukuko chamakampani am'banja la CMC, mabizinesi atsopano akupitiliza kukhazikitsidwa, mabizinesi akunja alowa. Kuchokera ku 2010 mpaka 2016, mayendedwe ndi chiwerengero cha mabizinesi akusintha, ndi nthawi yonse ya ndalama zopanda ndalama komanso chiwongoladzanja cha ndalama mu 2014. Mu 2016, ngakhale kuti katundu wapakhomo wa carboxymethyl cellulose ndi mankhwala ake amchere adakula pang'onopang'ono, mtengo wamtengo wapatali wogulitsa kunja unatsika kwambiri. Pambuyo pa 2017, ndalama zamabizinesi am'nyumba za CMC zidakhazikika kwambiri, ndi mabizinesi awiri okha. Ukadaulo wawo ndi zinthu zawo zimapikisana kwambiri. Mwachitsanzo, Hebi Fangrui Chemical idakhazikitsidwa potengera zida zoyambirira za kampani ya DuPont Danisco (Zhangjiagang) hydrophilic colloid ndi matekinoloje ofananirako ndi ogwira ntchito opanga. Fujian Meiyarui New Materials Company ndi kupanga batire kalasi mapadi etha mankhwala, kwa Ningde nthawi mabatire lifiyamu kuchita zinthu zothandizira.

1, kuchulukirachulukira kwamakampani apanyumba a sodium carboxymethyl cellulose, chifukwa chakuchepa kwa msika wofunikira kwambiri, monga momwe makampani azakudya am'nyumba amatulutsa pambuyo pa chaka cha 2017 mpaka kukula kocheperako. Kuchuluka kwa kufunikira m'malo ogwiritsira ntchito mwachilengedwe kudzabweretsa mpikisano wamitengo ndikuchotsa mphamvu zopanga. Kutuluka kwa kufunikira kwatsopano kudzakulitsa mabizinesi atsopano ndi mphamvu zatsopano zopangira, monga Fujian Meiyarui New Materials Company ndi Shandong Lihong Baoguan Cellulose Co., LTD., omwe akukulitsa mizere yopangira zinthu zama batire. 2, chitsanzo chabwino cha chitukuko cha mafakitale ndi teknoloji yowonjezereka, nthawi zonse imapanga zosowa zatsopano, pali kusiyana kwaumisiri pakati pa mpikisano. Komabe, vuto lachitukuko cha makampani achikhalidwe ndikuti njira zamakono zakhala zikuyimitsidwa, kukula kwa kufunikira kumakhala kokhazikika, ndipo pamene ochita mpikisano ambiri amakumana pamlingo womwewo wa luso, mpikisano wa homogenization umatsegulidwa. Pamene tekinoloje yaukadaulo siyingabwerezedwe, zosintha zina za msika ziyenera kupangidwa. 3. Kubwereza kwa zinthu zina zamsika, monga zinthu zazikulu, ntchito, nthaka ndi chilengedwe, zimadalira dzanja losawoneka la msika kwa nthawi yayitali, ndipo liyenera kudalira dzanja lowoneka la ndondomeko: kayendetsedwe ka chilengedwe; Misonkho yotsikirapo ya msonkho wa kunja; Kupititsa patsogolo miyezo ya khalidwe la mankhwala; Kwezani polowera kuti muzitha kupanga zatsopano.
