Daim ntawv thov ntawm cellulose ether yog heev heev, thiab kev txhawb nqa tag nrho ntawm kev lag luam hauv tebchaws yuav tsav cov cellulose kev lag luam ether. Tam sim no, daim ntawv thov ntawmCellulose etherNyob rau hauv Suav teb yog feem ntau concentrated hauv kev lag luam xws li cov ntaub ntawv tsim tsev, kev haus dej thiab cov tshuaj. Nrog rau daim ntawv thov thiab kev txhawb nqa ntawm cellulose ether rau lwm daim teb, qhov kev thov rau cellulose ethers hauv kev lag luam hauv dej yuav loj hlob sai.
Tsis tas li ntawd, lub teb chaws nce nqis peev hauv cov cuab yeej siv thiab kev txhim kho hluav taws xob, thiab lwm thaj chaw tsim kho ntawm cellulents ete dej, roj drilling thiab tshuaj lag luam. Kev lag luam kev loj hlob tsim cov rub tawm.
HPMCCov khoom lag luam yog siv nyob rau hauv ntau daim teb ntawm kev khwv nyiaj txiag hauv tebchaws hauv daim ntawv ntawm cov khoom sib ntxiv, yog li HPMC muaj cov neeg siv khoom siv tsawg dua hauv cov khoom me me. Raws li cov yam ntxwv ntawm cov neeg siv kawg hauv kev ua lag luam, HPMC cov khoom muag feem ntau txais yuav tus qauv tuam txhab.
Cov neeg tsis raug cai ntawm cellulose tau siv dav hauv kev lag luam kws tshuaj zoo li tshuaj, xws li cov tshuaj tawg, dispulsifiers thiab cov neeg sawv cev ua yeeb yaj kiab. Nws yog siv rau zaj duab xis txheej thiab cov nplaum ntawm cov ntsiav tshuaj tshuaj, thiab nws kuj tuaj yeem ua rau cov khoom siv visculs thiab muaj ntau yam ntxiv thiab muaj ntau cov tshuaj ntxuav. Piv nrog rau lwm qib ntawm cellulose khoom siv, sau nqi ntawm cov khoom tiav yog qhov siab, thiab ntxiv tus nqi ntawm cov khoom yog tus nqi qis. siab.
Tam sim no, cov neeg ua haujlwm ua lag luam rau 10-20% ntawm cov zis tawm ntawm tag nrho cov chaw muag tshuaj. Txij li thaum kuv lub teb chaws cov neeg saib xyuas tau pib lig thiab qib siab yog qhov tsawg, tsev txawb chaw muag tshuaj rau cov tshuaj uas tsis tshua muaj tshuaj, li 2-3%. Kws tsim kho cov tshuaj tau tsuas yog siv los ua cov khoom lag luam xws li npaj tshuaj lom neeg npaj tshuaj, suav cov tshuaj patent thiab cov khoom lag luam biochemical. Txij xyoo 2008 txog 2012, tag nrho cov tso zis cov nqi ntawm cov kws tshuaj yog 417.816 billion yuan, 88.77.957 billion yuan thiab 1,053.953billion Yun Riam tau1. Raws li kev faib ua feem ntawm kuv lub teb chaws cov chaw muag khoom suav rau 2% ntawm cov tso zis tag nrho ntawm cov tshuaj uas muaj nqis, 10 txhiab tus nqi, 18 txhiab Yuan thiab 21 Billion
Lub sijhawm "Kaum ob-xyoo phiaj xwm" lub sijhawm, Ministry of Science thiab Technology suav nrog cov kws tshuaj uas tsim nyog tshawb xyuas cov ntaub ntawv tshawb fawb tshiab. Nyob rau hauv "12-xyoo txoj kev tsim kho tsib lub xyoo ntawm cov chaw tsim tshuaj paus thiab cov ntaub ntawv ntim khoom siv tau ua cov khoom siv tseem ceeb rau kev txhim kho kev lag luam ntawm cov tshuaj. Raws li lub hom phiaj ntawm qhov nruab nrab ntawm kev loj hlob txhua xyoo yuav loj hlob ntawm cov tshuaj thiab cov ntaub ntawv siv tau sai sai hauv lub sijhawm yav tom ntej, thiab tib lub sijhawm txhawb nqa kev loj hlob ntawm cov qib tshuajHPMCKev ua lag luam.
