Sodium carboxymethyl cellulose (tseem hu ua carboxymethyl cellulose sodium ntsev, carboxymethyl cellulose, CMC luv luv) tau ua tiav los ntawm lub teb chaws Yelemees thaum ntxov xyoo pua 20th, thiab tam sim no tau dhau los ua cov khoom siv fiber ntau hauv ntiaj teb. Hom neeg tsis noj nqaij. Sodium carboxymethyl cellulose yog lub npe hu ua "kev lag luam monosodium glutamate", thiab nws cov kev siv qis qis yog qhov dav. Raws li cov kev xav tau tshwj xeeb, nws muab faib ua qib industrial, qib zaub mov thiab qib tshuaj. Cov cheeb tsam xav tau tseem ceeb yog cov khoom noj, tshuaj, tshuaj ntxuav tes, tshuaj ntxuav tes, luam yeeb, papermaking, ntawv hlau, cov ntaub ntawv hauv tsev, ceramics, textile printing thiab dyeing, roj drilling thiab lwm yam. Nws muaj cov yam ntxwv ntawm thickening, bonding, film forming, water retention, suspension, emulsification and shaping, and is used in corresponding fields.
Muaj ob txoj hauv kev tsim khoom tseem ceeb ntawm CMC: cov txheej txheem dej raws thiab cov txheej txheem organic hnyav. Txoj kev siv dej yog ib hom kev tshem tawm ntev dhau los. Txoj kev tsim cov dej uas twb muaj lawm hauv kuv lub tebchaws feem ntau siv cov txheej txheem ib txwm siv, thiab feem ntau ntawm lwm cov txheej txheem siv cov txheej txheem kneading hauv cov txheej txheem organic hnyav. Cov khoom tseem ceeb ntawm CMC xa mus rau purity, viscosity, degree ntawm kev hloov, PH tus nqi, particle loj, hnyav hlau thiab cov kab mob suav, ntawm cov ntsuas tseem ceeb tshaj plaws yog purity, viscosity thiab degree ntawm kev hloov.
Judging los ntawm cov txheeb cais ntawm Zhuochuang, muaj ntau manufacturers ntawm sodium carboxymethyl cellulose nyob rau hauv kuv lub teb chaws, tab sis kev faib ntawm manufacturers yog tawg. Lub peev xwm ntau lawm ntawm cov tuam txhab loj loj suav nrog ntau qhov kev faib ua feem, thiab muaj ntau lub lag luam me thiab nruab nrab, feem ntau nyob hauv Hebei, Henan, Shandong thiab lwm qhov chaw. . Raws li kev txheeb cais tsis tiav ntawm Zhuochuang, tag nrho cov peev txheej ntawm sodium carboxymethyl cellulose hauv kuv lub teb chaws tau tshaj 400,000 tons / xyoo, thiab tag nrho cov zis yog kwv yees li 350,000-400,000 tons / xyoo, uas ib feem peb ntawm cov peev txheej tau siv rau. export noj, thiab cov khoom seem yog digested domestically. Kev txiav txim siab los ntawm kev ntxiv tshiab yav tom ntej raws li Zhuo Chuang cov txheeb cais, tsis muaj ntau lub lag luam tshiab ntawm sodium carboxymethyl cellulose hauv kuv lub teb chaws, feem ntau yog nthuav tawm ntawm cov khoom siv uas twb muaj lawm, thiab cov peev txheej tshiab yog li 100,000-200,000 tons / xyoo. .
Raws li kev lis kev cai txheeb cais, carboxymethyl cellulose sodium ntsev txawv teb chaws tag nrho ntawm 5,740.29 tons nyob rau hauv 2012-2014, ntawm cov ntshuam loj tshaj plaws nyob rau hauv 2013 mus txog 2,355.44 tons, nrog ib tug compound kev loj hlob ntawm 9.3% nyob rau hauv 2012-2014. Los ntawm 2012 mus rau 2014, tag nrho cov export ntim ntawm sodium carboxymethyl cellulose yog 313,600 tons, uas loj tshaj export ntim nyob rau hauv 2013 yog 120,600 tons, thiab cov compound kev loj hlob ntawm 2012 txog 2014 yog hais txog 8.6%.
Raws li kev lag luam tseem ceeb ntawm sodium carboxymethyl cellulose, Zhuochuang tau faib cov zaub mov, cov khoom siv ntxhua khaub ncaws (tsuas yog tshuaj txhuam hniav), tshuaj, papermaking, ceramics, ntxhua hmoov, kev tsim kho, roj av thiab lwm yam lag luam, thiab muab raws li kev lag luam tam sim no. faib proportions. Cov dej hauv qab ntawm sodium carboxymethyl cellulose yog siv hauv kev lag luam ntxhua khaub ncaws, feem ntau hauv cov hmoov ntxhua khaub ncaws, suav nrog cov ntxhua khaub ncaws, suav txog 19.9%, ua raws li kev tsim kho thiab kev lag luam khoom noj, suav txog 15.3%.
