Daim ntawv thov ntawm cellulose ether yog dav heev, thiab tag nrho txoj kev loj hlob ntawm lub teb chaws kev lag luam yuav ncaj qha mus rau txoj kev loj hlob ntawm cellulose ether kev lag luam. Tam sim no, kev siv ntawmcellulose ethernyob rau hauv Tuam Tshoj yog mas concentrated nyob rau hauv kev lag luam xws li cov ntaub ntawv hauv tsev, roj drilling thiab tshuaj. Nrog rau daim ntawv thov thiab kev txhawb nqa ntawm cellulose ether hauv lwm qhov chaw, qhov kev thov rau cellulose ether nyob rau hauv downstream industries yuav loj hlob sai.
Tsis tas li ntawd, lub teb chaws kev nqis peev ntau ntxiv hauv kev tsim khoom vaj tse ruaj khov thiab kev txhim kho hluav taws xob, nrog rau kev tsim kho hauv nroog, thiab kev nce hauv cov neeg siv khoom hauv vaj tse, kev noj qab haus huv thiab lwm yam kev lag luam, yuav muaj kev cuam tshuam zoo rau cellulose ether los ntawm kev siv cov khoom siv, roj drilling thiab kev lag luam tshuaj. Kev lag luam kev loj hlob ua rau indirect rub.
HPMCCov khoom siv feem ntau yog siv nyob rau hauv ntau qhov chaw ntawm lub teb chaws kev khwv nyiaj txiag nyob rau hauv daim ntawv ntawm additives, yog li HPMC muaj cov yam ntxwv ntawm kev siv dav thiab tawg khiav ri niab, thiab downstream kawg cov neeg siv feem ntau yuav nyob rau hauv me me. Raws li cov yam ntxwv ntawm cov neeg siv khoom sib cais hauv kev ua lag luam, HPMC cov khoom muag feem ntau txais yuav tus qauv muag khoom.
Nonionic cellulose ethers yog dav siv nyob rau hauv kev lag luam kws tshuaj raws li kws tshuaj excipients, xws li thickeners, dispersants, emulsifiers thiab film-forming agents. Nws yog siv rau zaj duab xis txheej thiab nplaum rau cov ntsiav tshuaj tshuaj, thiab nws kuj yuav siv tau rau ncua kev kawm ntawv, ophthalmic npaj, sustained thiab tswj kev tso tawm matrix thiab floating ntsiav tshuaj, thiab lwm yam Piv nrog rau lwm qib ntawm cov khoom lag luam cellulose ether, kev sau tus nqi ntawm cov khoom tiav yog tsawg, cov nqi tsim khoom yog siab, thiab tus nqi ntxiv ntawm cov khoom kuj tseem siab. siab.
Tam sim no, txawv teb chaws kws tshuaj excipients account rau 10-20% ntawm tus nqi tso zis ntawm tag nrho cov tshuaj npaj. Txij li thaum kuv lub teb chaws cov tshuaj excipients pib lig thiab tag nrho cov theem qis, cov kws tshuaj hauv tsev suav nrog cov feem tsawg ntawm tag nrho cov tshuaj, txog 2-3%. Pharmaceutical excipients feem ntau yog siv rau hauv kev npaj cov khoom xws li tshuaj npaj, suav tshuaj patent thiab biochemical khoom. Los ntawm 2008 txog 2012, tag nrho cov khoom tsim tawm tus nqi ntawm cov tshuaj yog 417.816 billion yuan, 503.315 billion yuan, 628.713 billion yuan, 887.957 billion yuan thiab 1,053.953 billion yuan feem 1. Raws li qhov kev faib ua feem ntawm kuv lub teb chaws cov tshuaj excipients accounting rau 2% ntawm tag nrho cov zis tus nqi ntawm kev npaj tshuaj, tag nrho cov zis tus nqi ntawm domestic kws excipients los ntawm 2008 mus rau 2012 yog hais txog 8 billion yuan, 10 billion yuan, 12.5 billion yuan, 18 billion yuan.
Thaum lub sij hawm "Twelfth Five-Year Plan", Ministry of Science thiab Technology suav nrog cov thev naus laus zis tseem ceeb rau kev txhim kho cov khoom siv tshuaj tshiab los ua cov ncauj lus tshawb fawb. Nyob rau hauv "12th Tsib Xyoo Kev Txhim Kho Txoj Kev Npaj ntawm Kev Lag Luam Pharmaceutical Industry" tau tshaj tawm los ntawm Ministry of Industry thiab Information Technology, ntxiv dag zog rau kev txhim kho thiab siv cov khoom siv tshuaj tshiab thiab cov khoom ntim tau teev tseg raws li thaj chaw tseem ceeb rau kev txhim kho kev lag luam tshuaj. Raws li lub hom phiaj ntawm qhov nruab nrab txhua xyoo kev loj hlob ntawm 20% nyob rau hauv tag nrho cov zis tus nqi ntawm kev lag luam kws tshuaj nyob rau hauv "Twelfth Tsib-xyoo Plan" ntawm Ministry of Industry thiab Information Technology, lub lag luam loj ntawm cov tshuaj excipients yuav loj hlob sai heev nyob rau hauv lub neej yav tom ntej, thiab nyob rau tib lub sij hawm txhawb txoj kev loj hlob ntawm cov tshuaj qib.HPMCkev ua lag luam.
