Sodium Carboxyl methyl Cellulose (Carboxyl methyl Cellulose), inonzi CMC, is cellulose ether, carboxyl methyl inotorwa kubva ku cellulose, inozivikanwawo secellulose chingamu, ndiyo inonyanya kukosha ionic cellulose chingamu. Yakagadzirwa mukutengeserana muEurope mukutanga kwema1910 uye yakashandiswa se colloid uye binder. Muna 1947, yakatenderwa kushandiswa sekuwedzera muindasitiri yekugadzira chikafu uye ine kukora mhedzisiro. Iyo aqueous solution ye sodium carboxymethyl cellulose ine mabasa ekuita thickening, bonding, firimu kuumbwa, inodzivirira inonamatira, kuchengetedza unyoro, emulsification uye kumiswa, etc. Mishonga yakawanda ndeye petroleum giredhi, giredhi rekudya, giredhi remakemikari zuva nezuva, giredhi remishonga uye bhatiri giredhi CMC. Pakati pavo, bhatiri-giredhi CMC inoshandiswa sebhainda reti lithium bhatiri electrode mapepa, uye kudiwa kwayo kwemusika kwakakura nekukurumidza mumakore achangopfuura nekukwira kweindasitiri yemagetsi emagetsi epamba.

Process tekinoroji

Iyo yekugadzira nzira ye sodium carboxymethyl cellulose inosanganisira yemvura yepakati nzira, yakaderera solvent nzira, slurry nzira (yakawanda solvent nzira) zvichingodaro. Izvo zvakakosha zvekushandisa zvakanatswa cellulose, uye mutsauko uripo pakati peaqueous nzira uye maviri ekupedzisira ndewekuti "hapana organic solvent senge doro seyekuita svikiro mukuita alkalization uye etherification". Iyo yehunyanzvi chikumbaridzo chemvura yepakati nzira haina kukwirira, asi kuchena uye kutsiva kufanana kwezvigadzirwa zvinogadzirwa hazvina kukwirira, uye zvinogona kushandiswa chete kune yakaderera-yekupedzisira kudiwa munda. Zvigadzirwa zvehutsanana zvakakwirira zvinodawo kucheneswa, kucheneswa CMC ine chipingamupinyi chakakwirira - yepamberi yekudyara michina uye yakawedzera maitiro anosimudzira zvakanyanya mutengo, slurry nzira idanho repamberi.

Indasitiri mamiriro

Kushambadzira kweCMC kwave kuda kusvika makore zana, tekinoroji yehunyanzvi yakakura kwazvo uye hapana budiriro yakakura kwemakore mazhinji, ndeyezvigadzirwa zvemakemikari echinyakare, kwete zvekutarisisa mabhizinesi makuru emakemikari, ikozvino kugadzirwa kwekunze kwemabhizinesi eCMC ane Herklex (Ashland), makwikwi Lu, Japan bepa zvichingodaro. Indasitiri yeCMC yemumba yakapinda munzira inokurumidza yebudiriro mushure me1998. Zvikurukuru, pakutanga kwezana ramakore rechi 21, kudiwa kwe sodium carboxymethyl cellulose mumisika yemumba uye yepasirese kuri kuwedzera, uye avhareji yekukura kwegore rekushandisa mudzimba CMC pakati pa2006 na2010 yasvika 17%, iyo yakaburitsa akawanda ari nyore kugadzirwa kwesodium uye midziyo yesodium padyo nemidziyo yesodium uye cellulose. peak, maitiro avo akafanana. Musiyano uripo pakati pemakambani ndeyekugadzika kwekupihwa kwezvinhu zvakachipa zvekushandisa, zvakatipoteredza zvine hushamwari mari yekushandisa uye mhando yechigadzirwa.

Kubva pamaonero enguva yekupinda kwemaindasitiri, kupinda kwebhizinesi kwakatanga muna 1998, kwakaenderera kusvika 2016, uye kwakasvika pakakwirira muna 2014. Pakati pavo, 2001-2009 ndiyo nguva yegoridhe yekusimudzirwa kweindasitiri yemumba yeCMC, mabhizimisi matsva anoramba achisimbiswa, mabhizimisi ekunze akapinda. Kubva 2010 kusvika 2016, kukurumidza uye nhamba yemabhizimisi ari kuchinja, pamwe chete nenguva yekudyara isina chinhu uye peak yekudyara muna 2014. Muna 2016, kunyange zvazvo huwandu hwekutengesa kunze kwenyika kwecarboxymethyl cellulose uye zvigadzirwa zvayo zvemunyu zvakawedzera zvishoma nezvishoma, mutengo wekutengesa kunze wakawira kune imwe nhoroondo yakaderera. Mushure megore ra2017, kudyara muindasitiri yemumba yeCMC kwakadzikira zvakanyanya, paine mabhizinesi maviri chete matsva. Tekinoroji yavo uye zvigadzirwa zvakanyanya kukwikwidza. Semuyenzaniso, Hebi Fangrui Chemical yakavambwa nekutora iyo yekutanga DuPont Danisco (Zhangjiagang) hydrophilic colloid kambani michina uye ane hukama matekinoroji nevashandi vekugadzira. Fujian Meiyarui New Materials Company inongova kugadzirwa kwebhatiri giredhi cellulose ether zvigadzirwa, zveNingde nguva lithium mabhatiri kuita zvinhu zvinotsigira.

mhedziso

1, kusimba kweiyo indasitiri yemumba sodium carboxymethyl cellulose, zvine hungwaru nekuda kwekudzikira kwekudzika kwemusika kukura kwemusika, senge indasitiri yechikafu yepamba inobuda mushure megore ra2017 ichipinda munguva yakaderera yekukura. Iyo saturation yekudiwa munzvimbo dzechinyakare dzekushandisa zvinozotungamira kumakwikwi emitengo uye kubvisa huwandu hwekugadzira. Kubuda kwechido chitsva kucharima mabhizinesi matsva uye huwandu hutsva hwekugadzira, seFujian Meiyarui New Materials Company uye Shandong Lihong Baoguan Cellulose Co., LTD., ari kuwedzera mitsara yekugadzira yezvigadzirwa zvebhatiri-giredhi. 2, iyo yakanakira modhi yekusimudzira indasitiri inoenderera tekinoroji iteration, inogara ichigadzira zvitsva zvinodiwa, pane tekinoroji gaka pakati pevanokwikwidza. Nekudaro, dambudziko rekusimudzira indasitiri yechinyakare nderekuti tekinoroji yemaitiro yakamira, kukura kwekuda kwakagadzikana, uye kana vakwikwidzi vakawanda vachisangana padanho rakafanana rehunyanzvi, makwikwi ehomogenization anovhurwa. Kana iyo tekinoroji factor isingagone kudzokororwa, imwe musika factor iterations inoda kugadzirwa. 3. Kudzokororwa kwezvimwe zvinhu zvemusika, zvakadai semari, basa, ivhu uye nharaunda yezvakatipoteredza, inovimba neruoko rusingaoneki rwemusika kwenguva yakareba, uye inoda kuvimba neruoko runooneka rwemitemo: kutonga kwezvakatipoteredza; Mitemo yakaderera yemutero wekutengesa kunze kwenyika; Kuvandudza zvigadzirwa zvemhando yepamusoro; Simudza chikumbaridzo chekupinda kune hutsva hwekugadzira.
