Cellulose ether tau tshem ntawm cov ntawv thov tsawg thiab nrawm hloov pauv thiab kho dua tshiab

Dej-soluble sodium carboxymethyl cellulose, hydrox cellulose, tshuaj tua kab cellulose, cov tshuaj pleev cov tshuaj pleev pob zeb thiab cov neeg sawv cev siv tau hauv cov chaw muag tshuaj expipients. Saib rau hauv lub ntiaj teb, muaj ntau cov tuam txhab ua lag luam txawv teb chaws (shin-etsu Nyij Pooj) tau pom ntau ntau lawm lossis kev sib koom ua ke hauv daim teb no. Daim ntawv thov tawm tswv yim hauv. Dow Wolfe tshaj tawm tias nws yuav ntxiv dag zog rau nws lub siab xav ua lag luam, cov khoom siv thov tshuaj, thiab nws cov cuab yeej tshawb fawb yuav siv zog kom txav ze rau kev ua lag luam. Dow tshuaj Wold Cellulose faib thiab xim Corporation ntawm Tebchaws Asmeskas tau tsim cov kws tshaj lij thoob ntiaj teb, muaj ntau cov neeg ua haujlwm tshawb nrhiav cov kws tshawb fawb hauv kwv yees li 160 lub teb chaws. Ashland muaj cov hauv paus ntau lawm hauv Beijing, Tianjin, Nanjie, Changzhou, Chanpshan thiab tau nqis peev rau peb cov chaw tshawb fawb hauv Shanghai thiab Nanjing.

Raws li kev txheeb cais los ntawm lub vev xaib cellulose koom haum, nyob rau xyoo 2017, lub tsev cellulose ether yog 373,000 tons, thiab ntim ntim yog 360,000 tons. Hauv 2017, qhov muag tiag tiag muag ntim ntawm Ionic CMC yog 234,000 tons, nce ntxiv ntawm 18.61% xyoo ntawm-ionic CMC yog 126,000 tons, nce ntxiv 8.2% thawm xyoo. Ntxiv rau HPMC (tsev cov khoom siv qib), cov khoom lag luam HPM), HPMC (HPC (CareC (HITCRArcing cov qauv thiab lawv cov khoom lag luam thiab muag khoom tau txuas ntxiv ntxiv. Cov cellulic ether tau loj hlob sai rau ntau tshaj kaum xyoo, thiab nws cov zis tau dhau los ua thawj hauv ntiaj teb. Txawm li cas los xij, cov khoom ntawm feem ntau cellulose ether cov tuam txhab yog tsuas yog siv nyob rau hauv nruab nrab thiab qis-kawg teb ntawm kev lag luam, thiab ntxiv tus nqi tsis siab.

Tam sim no, feem ntau hauv cellule cellulose ether cov kev lag luam yog nyob rau hauv lub sijhawm tseem ceeb ntawm kev hloov pauv thiab txhim kho. Lawv yuav tsum txuas ntxiv kev tshawb nrhiav cov khoom lag luam thiab kev tsim kho cov khoom lag luam hauv ntiaj teb, thiab ua tiav cov kev lag luam thoob ntiaj teb, thiab ua tiav benign thiab ntsuab kev loj hlob.
