I-Sodium Carboxyl methyl Cellulose (i-Carboxyl methyl Cellulose), ebizwa ngokuthi i-CMC, i-cellulose ether, i-carboxyl methyl ephuma ku-cellulose, eyaziwa nangokuthi i-cellulose gum, iyinshingamu ye-ionic cellulose ebaluleke kakhulu. Yakhiqizwa ngokuhweba eYurophu ekuqaleni kwawo-1910 futhi yayisetshenziswa njenge-colloid ne-binder. Ngo-1947, kwavunyelwa ukuthi kusetshenziswe njengesengezo embonini yokucubungula ukudla futhi kunomphumela wokuqina. Isixazululo esinamanzi se-sodium carboxymethyl cellulose sinemisebenzi yokuqina, ukubopha, ukwakheka kwefilimu, i-adhesive evikelayo, ukugcinwa komswakama, i-emulsification nokumiswa, njll. Imikhiqizo evamile yibanga le-petroleum, ibanga lokudla, ibanga lamakhemikhali nsuku zonke, ibanga lemithi kanye nebanga lebhethri CMC. Phakathi kwazo, i-CMC yezinga lebhethri isetshenziswa njengesibopho samashidi e-electrode yebhethri ye-lithium, futhi isidingo sayo semakethe sikhule ngokushesha eminyakeni yamuva nje ngokukhula kwemboni yezimoto zamandla entsha yasekhaya.

Ubuchwepheshe benqubo

Inqubo yokukhiqiza ye-sodium carboxymethyl cellulose ihlanganisa indlela ephakathi kwamanzi, indlela ye-solvent ephansi, indlela ye-slurry (indlela ye-solvent eminingi) njalonjalo. Izinto zokusetshenziswa eziyisihluthulelo ziyi-cellulose ecwengiwe, futhi umehluko phakathi kwendlela enamanzi kanye nalezi ezimbili zokugcina ukuthi "ayikho i-solvent ephilayo efana notshwala njengendlela yokusabela ohlelweni lwe-alkalization kanye ne-etherification". Umkhawulo wezobuchwepheshe wendlela ephakathi kwamanzi awuphezulu, kodwa ukuhlanzeka nokushintshaniswa okufanayo kwemikhiqizo ekhiqizwayo akuphakeme, futhi kungasetshenziswa kuphela emkhakheni wesidingo esiphansi. Imikhiqizo yokuhlanzeka okuphezulu nayo idinga ukucwengisiswa, i-CMC ecwengisisiwe inomgoqo ophezulu - ukutshalwa kwezimali kwemishini ethuthukisiwe kanye nenqubo eyandisiwe izokhuphula kakhulu izindleko, indlela ye-slurry iyinqubo ethuthuke kakhulu.

Isimo semboni

Ukuhweba kwe-CMC sekuyiminyaka engaba yikhulu, ubuchwepheshe benqubo buvuthwe kakhulu futhi akukho mpumelelo enkulu iminyaka eminingi, ingeyemikhiqizo yamakhemikhali yendabuko, hhayi ukunaka kwamabhizinisi amakhulu amakhemikhali, ukukhiqizwa kwamanje kwamanye amazwe kwamabhizinisi e-CMC aneHerklex (Ashland), umncintiswano we-Lu, iphepha laseJapane njalonjalo. Imboni yasekhaya ye-CMC yangena emgudwini osheshayo wentuthuko emva kuka-1998. Ikakhulukazi, ekuqaleni kwekhulu lama-21, isidingo se-sodium carboxymethyl cellulose ezimakethe zasekhaya nezamazwe ngamazwe siyachuma, futhi isilinganiso sonyaka sokukhula kwezinga lokusetshenziswa kwe-CMC yasekhaya phakathi kuka-2006 no-2010 sesifinyelele ku-17%, okuye kwaveza izinqubo eziningi ezilula zokukhiqiza i-carboxymethyl kanye ne-cellulose ye-sodium ne-cellulose eyikhulu. ukuphakama, izinqubo zabo zifana kakhulu. Umehluko phakathi kwezinkampani ukutholakala okuzinzile kwezinto ezingavuthiwe ezishibhile, izindleko zokusebenza ezihambisana nemvelo kanye nekhwalithi yomkhiqizo.

Ngokombono wesikhathi sokungena embonini, ukungena kwamabhizinisi kwaqala ngo-1998, kwaqhubeka kwaze kwaba ngu-2016, futhi kwafinyelela inani eliphakeme ngo-2014. Phakathi kwabo, i-2001-2009 yinkathi yegolide yokuthuthukiswa kwemboni yasekhaya ye-CMC, amabhizinisi amasha ayaqhubeka nokusungulwa, amabhizinisi angaphandle angenile. Kusukela ngo-2010 kuya ku-2016, ijubane nenani lamabhizinisi liyashintsha, kokubili isikhathi esingenalutho sokutshala izimali kanye nenani eliphakeme lokutshalwa kwezimali ngo-2014. Ngo-2016, nakuba ivolumu yokuthekelisa yasekhaya ye-carboxymethyl cellulose kanye nemikhiqizo yayo kasawoti yanda kancane kancane, intengo yokuthekelisa emaphakathi yehle yaba phansi ngokomlando. Ngemuva kuka-2017, ukutshalwa kwezimali embonini yasekhaya ye-CMC sekupholile kakhulu, kunamabhizinisi amasha amabili kuphela. Ubuchwepheshe nemikhiqizo yabo kuncintisana kakhulu. Isibonelo, i-Hebi Fangrui Chemical yasungulwa ngokumunca izisetshenziswa zangempela zenkampani ye-DuPont Danisco (Zhangjiagang) hydrophilic colloid kanye nobuchwepheshe obuhlobene nabasebenzi bokukhiqiza. I-Fujian Meiyarui New Materials Company ikhiqiza kuphela imikhiqizo yebhethri ye-cellulose ether, izikhathi ze-Ningde amabhethri e-lithium ukwenza izinto ezisekelayo.

isiphetho

1, ukuncishiswa kwamandla embonini yasekhaya ye-sodium carboxymethyl cellulose, ngokufanelekile ngenxa yokwehla kokukhula kwemakethe yesidingo esiphansi, njengokuphuma kwemboni yezokudla yasekhaya ngemuva kuka-2017 esikhathini sokukhula ngesivinini esiphansi. Ukugcwala kwesidingo ezindaweni zokusetshenziswa kwendabuko kuzoholela ngokwemvelo emqhudelwaneni wamanani futhi kuqede amandla okukhiqiza. Ukuvela kwesidingo esisha kuzothuthukisa amabhizinisi amasha namandla amasha okukhiqiza, njenge-Fujian Meiyarui New Materials Company kanye ne-Shandong Lihong Baoguan Cellulose Co., LTD., andisa imigqa yokukhiqiza yemikhiqizo yebhethri. 2, imodeli ekahle yokuthuthukiswa kwemboni ukuphindaphinda kobuchwepheshe okuqhubekayo, kudala izidingo ezintsha, kukhona igebe lobuchwepheshe phakathi kwezimbangi. Kodwa-ke, inkinga yokuthuthukiswa kwemboni yendabuko ukuthi ubuchwepheshe benqubo bumile, ukukhula kwesidingo kuzinzile, futhi lapho izimbangi eziningi zihlangana ezingeni elifanayo lobuchwepheshe, umncintiswano we-homogenization uyavulwa. Uma isici sobuchwepheshe singenakuphindwa, okunye ukuphindaphinda kwesici semakethe kumele kudalwe. 3. Ukuphindwaphindwa kwezinye izici zemakethe, njengezici zemali, abasebenzi, umhlaba kanye nemvelo, kuncike esandleni esingabonakali semakethe isikhathi eside, futhi kudinga ukuncika esandleni esibonakalayo senqubomgomo: ukubusa kwemvelo; Amazinga aphansi esaphulelo sentela yokuthumela ngaphandle; Thuthukisa amazinga ekhwalithi yomkhiqizo; Phakamisa umkhawulo wokungenela umthamo omusha wokukhiqiza.
