I-Sodium Carboxyl methyl Cellulose (iCarboxyl methyl Cellulose), ekubhekiselwa kuyo njenge-CMC, yi-cellulose ether, i-carboxyl methyl ephuma kwi-cellulose, ekwabizwa ngokuba yi-cellulose gum, yeyona gum ye-ionic cellulose ibalulekileyo. Yayiveliswe ngezorhwebo eYurophu ekuqaleni kweminyaka yoo-1910 kwaye yayisetyenziswa njenge-colloid kunye ne-binder. Ngo-1947, yavunyelwa ukuba isetyenziswe njengesongezo kwishishini lokulungisa ukutya kwaye inomphumela wokutyeba. Isisombululo samanzi se-sodium carboxymethyl cellulose sinemisebenzi yokuqina, ukudibanisa, ukubunjwa kwefilimu, i-adhesive ekhuselayo, ukugcinwa komswakama, i-emulsification kunye nokumiswa, njl. Phakathi kwabo, i-CMC ye-battery-grade isetyenziswa njenge-binder ye-lithium ibhetri ye-electrode sheets, kwaye imfuno yayo yemarike ikhule ngokukhawuleza kwiminyaka yamuva nje ngokunyuka kweshishini elitsha lemoto yasekhaya.

Itekhnoloji yenkqubo

Inkqubo yokuvelisa i-sodium carboxymethyl cellulose ibandakanya indlela ephakathi kwamanzi, indlela ye-solvent ephantsi, indlela ye-slurry (iendlela ezininzi zokunyibilikisa) njalo njalo. Izinto eziphambili zekrwada yiselulosi esulungekileyo, kwaye umahluko phakathi kwendlela enamanzi kunye nezi zimbini zokugqibela kukuba "akukho nto i-solvent ye-organic efana notywala njengendlela yokusabela kwinkqubo ye-alkalization kunye ne-etherification". Umda wobugcisa wendlela ephakathi kwamanzi awukho phezulu, kodwa ukucoceka kunye nokutshintshwa okufanayo kweemveliso eziveliswayo aziphezulu, kwaye zinokusetyenziswa kuphela kwintsimi yemfuno ephantsi. Iimveliso eziphakamileyo zokucoceka nazo zifuna ukucokiswa, iCMC ecociweyo inomqobo ophezulu - utyalo-mali lwezixhobo eziphambili kunye nenkqubo eyandisiweyo iya kutyhala kakhulu iindleko, indlela yodaka yinkqubo ephezulu kakhulu.

Ubume boshishino

I-CMC yorhwebo sele iphantse ibe yikhulu leminyaka, iteknoloji yenkqubo ikhulile kakhulu kwaye akukho mpumelelo enkulu iminyaka emininzi, iyeyemveliso yeekhemikhali zemveli, kungekhona ingqalelo yamashishini amakhulu ekhemikhali, imveliso yangoku yangaphandle yamashishini e-CMC aneHerklex (Ashland), ukhuphiswano Lu, iphepha laseJapan njalo njalo. Ushishino lwasekhaya lweCMC lwangena kumzila okhawulezayo wophuhliso emva ko-1998. Ngokukodwa, ekuqaleni kwenkulungwane yama-21, imfuno ye-sodium carboxymethyl cellulose kwiimarike zasekhaya nezamazwe ngamazwe iyakhula, kwaye umyinge wokukhula wonyaka wokusetyenziswa kwe-CMC yasekhaya phakathi ko-2006 no-2010 ufikelele kwi-17%, eye yavelisa iinkqubo ezininzi ze-carboxymethyl kunye nezixhobo ezilula ze-carboxymethyl kufuphi ne-cellulose ye-carboxymethylprises. Incopho, iinkqubo zabo ziyafana. Umahluko phakathi kweenkampani kukubonelelwa okuzinzileyo kwemathiriyeli ekrwada etshiphu, iindleko zokusebenza ezihambelana nokusingqongileyo kunye nomgangatho wemveliso.

Ukususela kumbono wexesha lokungena kwishishini, ukungena kwamashishini kwaqala ngo-1998, kwaqhubeka kwada kwayi-2016, kwaye kwafikelela kwincopho ngo-2014. Phakathi kwabo, i-2001-2009 yithuba legolide lophuhliso loshishino lwasekhaya lwe-CMC, amashishini amatsha ayaqhubeka nokusekwa, amashishini angaphandle angenile. Ukususela kwi-2010 ukuya kwi-2016, isantya kunye nenani lamashishini atshintshayo, kunye nexesha lotyalo-mali elingenanto kunye nencopho yotyalo-mali kwi-2014. Kwi-2016, nangona umthamo wasekhaya wokuthumela ngaphandle kwe-carboxymethyl cellulose kunye neemveliso zayo zetyuwa zanda ngokukhawuleza, ixabiso lokuthumela kwamanye amazwe liye lawela kwimbali ephantsi. Emva kowama-2017, utyalo-mali kushishino lwasekhaya lwe-CMC luphole kakhulu, ngamashishini amatsha amabini kuphela. Itekhnoloji kunye neemveliso zabo zikhuphisana ngakumbi. Umzekelo, iHebi Fangrui Chemical yasekwa ngokufunxa iDuPont Danisco (Zhangjiagang) izixhobo zenkampani ye-hydrophilic colloid kunye nobuchwepheshe obunxulumeneyo kunye nabasebenzi bemveliso. Fujian Meiyarui New Materials Inkampani imveliso kuphela ibhetri grade cellulose iimveliso ether, kuba amaxesha Ningde lithium iibhetri ukwenza izinto ezixhasayo.

isiphelo

1, ukucutheka komthamo weshishini lasekhaya le-sodium carboxymethyl cellulose, ngokungakhethi cala ngenxa yokwehla kokukhula kwemfuno yemalike esezantsi, njengemveliso yokutya yasekhaya emva kowama-2017 ukuya kwixesha lokukhula ngesantya esisezantsi. Ukuzaliswa kwemfuno kwiindawo zesicelo zendabuko kuya kukhokelela ngokwemvelo kukhuphiswano lwexabiso kunye nokuphelisa amandla okuvelisa. Ukuvela kwemfuno entsha kuya kuvelisa amashishini amatsha kunye nomthamo omtsha wemveliso, njengeFujian Meiyarui New Materials Company kunye neShandong Lihong Baoguan Cellulose Co., LTD., Ezandisa imigca yemveliso yeemveliso zebhetri. I-2, imodeli efanelekileyo yophuhliso lweshishini iteration yetekhnoloji eqhubekayo, idala rhoqo iimfuno ezintsha, kukho umsantsa wobugcisa phakathi kwabakhuphisana nabo. Nangona kunjalo, ingxaki yophuhliso lweshishini lemveli kukuba iteknoloji yenkqubo imile, ukukhula kweemfuno kuzinzile, kwaye xa abakhuphisana abaninzi behlangana kwinqanaba elifanayo lobugcisa, ukhuphiswano lwe-homogenization luvulwa. Xa into yetekhnoloji ayinakuphinda iphindwe, ezinye izinto eziphindaphindwayo zentengiso kufuneka zenziwe. 3. Ukuphindaphindwa kweminye imiba yemalike, njengemiba yemali, abasebenzi, umhlaba kunye nokusingqongileyo kwendalo, kuxhomekeke kwisandla esingabonakaliyo semarike ixesha elide, kwaye kufuneka kuxhomekeke kwisandla esibonakalayo somgaqo-nkqubo: ulawulo lokusingqongileyo; Amazinga asezantsi esaphulelo kwirhafu yokuthumela ngaphandle; Ukuphucula umgangatho wemveliso; Phakamisa umda wokungena kumthamo omtsha wemveliso.
