1. Cov yam ntxwv zoo
(1) Txoj cai txhawb nqa
Raws li bio-raws li cov khoom siv tshiab thiab cov khoom siv ntsuab thiab ib puag ncig tus phooj ywg, kev siv dav dav ntawmcellulose ethernyob rau hauv kev lag luam teb yog txoj kev loj hlob ntawm kev tsim ib puag ncig-phooj ywg thiab kev pab txuag lub neej yav tom ntej. Txoj kev loj hlob ntawm kev lag luam yog nyob rau hauv txoj kab nrog kuv lub teb chaws lub hom phiaj ntawm kev ua tiav kev lag luam ruaj khov. Tsoomfwv Suav tau tshaj tawm cov cai thiab kev ntsuas ua tiav xws li "National Medium thiab Long-Term Science thiab Technology Development Plan (2006-2020)" thiab "Kev Tsim Kho Kev Lag Luam "Twelfth Five-Year Plan" Development Plan" los txhawb kev lag luam cellulose ether.
Raws li "2014-2019 Tuam Tshoj Pharmaceutical Food Grade Cellulose Ether Market Monitoring and Investment Prospect Analysis Report" tso tawm los ntawm Tuam Tshoj Kev Lag Luam Xov Xwm Network, lub teb chaws kuj tau tsim cov qauv kev tiv thaiv ib puag ncig nruj, uas tau hais txog kev tiv thaiv ib puag ncig rau ib qho tshiab. qib. Kev nplua loj dua rau kev ua qias tuaj ib puag ncig tau ua lub luag haujlwm zoo hauv kev daws teeb meem xws li kev sib tw tsis sib haum xeeb hauv kev lag luam cellulose ether thiab kev koom ua ke kev lag luam muaj peev xwm.
(2) Lub zeem muag ntawm cov ntawv thov hauv qab yog dav thiab qhov kev thov nce ntxiv
Cellulose ether yog lub npe hu ua "kev lag luam monosodium glutamate" thiab tuaj yeem siv rau ntau yam kev lag luam hauv lub tebchaws. Kev loj hlob ntawm kev lag luam yuav inevitably tsav kev loj hlob ntawm cellulose ether kev lag luam. Nrog rau kev txhim kho txuas ntxiv ntawm kuv lub teb chaws txoj kev lag luam hauv nroog thiab tsoomfwv cov peev txheej ruaj khov thiab cov vaj tse pheej yig, kev tsim kho thiab cov khoom siv hauv tsev yuav ua rau muaj kev xav tau ntawm cellulose ether. Hauv kev lag luam tshuaj thiab zaub mov, tib neeg txoj kev paub txog kev noj qab haus huv thiab kev tiv thaiv ib puag ncig yog maj mam nce. Physiologically harmless thiab non-polluting cellulose ether cov khoom xws li HPMC yuav maj mam hloov lwm yam ntaub ntawv uas twb muaj lawm thiab tsim sai heev. Tsis tas li ntawd, daim ntawv thov ntawm cellulose ether hauv txheej, ceramics, tshuaj pleev ib ce, tawv, ntawv, roj hmab, tshuaj niaj hnub thiab lwm yam kev lag luam tau dhau los ua ntau thiab ntau dua.
(3) Kev nce qib hauv kev tsim kho kev lag luam
Nyob rau theem pib ntawm txoj kev loj hlob ntawm kuv lub teb chaws txoj kev lag luam cellulose ether, ionic carboxymethyl cellulose ether (CMC) yog cov khoom tseem ceeb. Nrog rau kev tsim khoom ntawm ionic cellulose ether sawv cev los ntawm PAC thiab non-ionic cellulose ether sawv cev los ntawm HPMC Nrog rau kev txhim kho thiab kev loj hlob ntawm cov txheej txheem, daim ntawv thov teb ntawm cellulose ether tau nthuav dav. Cov thev naus laus zis tshiab thiab cov khoom lag luam tshiab yuav hloov pauv cov khoom lag luam cellulose ether yav dhau los thiab txhawb txoj kev loj hlob ntawm kev lag luam.
2. Yam tsis zoo
(1) Kev tsis sib haum xeeb hauv kev ua lag luam
Piv nrog rau lwm cov dej num tshuaj, lub sij hawm tsim kho ntawm cellulose ether project yog luv luv thiab cov khoom siv dav siv, yog li muaj qhov tshwm sim ntawm kev tsis sib haum xeeb hauv kev lag luam. Tsis tas li ntawd, vim tsis muaj cov qauv kev lag luam thiab cov qauv kev lag luam uas tsim los ntawm lub xeev, muaj qee cov tuam txhab me me uas tsis tshua muaj kev txawj ntse thiab cov peev nyiaj tsawg hauv kev lag luam; Qee qhov ntawm lawv muaj teeb meem ib puag ncig rau kev sib txawv ntawm cov txheej txheem tsim khoom, thiab siv cov khoom siv tsis zoo, cov nqi qis thiab cov nqi qis coj los ntawm kev tiv thaiv ib puag ncig qis tau cuam tshuam rau kev lag luam cellulose ether, ua rau muaj kev sib tw tsis sib haum xeeb hauv kev lag luam. . Tom qab kev qhia txog cov thev naus laus zis tshiab thiab cov khoom tshiab, kev tshem tawm cov txheej txheem ntawm kev ua lag luam yuav txhim kho lub xeev uas twb muaj lawm ntawm kev sib tw tsis sib haum xeeb.
(2) Cov khoom siv high-tech thiab cov khoom muaj nqis ntxiv yog raug rau kev tswj xyuas txawv teb chaws
Kev lag luam txawv teb chaws cellulose ether tau pib ua ntej, thiab cov tuam txhab tsim khoom sawv cev los ntawm Dow Chemical thiab Hercules Group hauv Tebchaws Meskas yog nyob rau hauv txoj haujlwm tseem ceeb ntawm cov qauv tsim thiab thev naus laus zis. Kev txwv los ntawm kev siv thev naus laus zis, cov tuam txhab hauv teb chaws cellulose ether feem ntau tsim cov khoom lag luam qis-nqi ntxiv nrog cov txheej txheem yooj yim thiab cov khoom lag luam uas tsis tshua muaj siab dawb paug, thaum cov tuam txhab txawv teb chaws tau ua lag luam rau cov khoom lag luam muaj txiaj ntsig zoo-ntxiv cellulose ether los ntawm kev siv cov txiaj ntsig zoo; Yog li ntawd, nyob rau hauv domestic cellulose ether kev ua lag luam, high-end khoom yuav tsum tau imported thiab low-end khoom muaj zog export raws. Txawm hais tias lub peev xwm tsim khoom ntawm domestic cellulose ether kev lag luam tau loj hlob sai, nws cov kev sib tw hauv kev lag luam thoob ntiaj teb tsis muaj zog. Nrog rau txoj kev loj hlob ntawm kev lag luam cellulose ether, cov txiaj ntsig ntawm cov khoom lag luam uas tsis muaj nqis ntxiv yuav poob mus ntxiv, thiab cov tuam txhab lag luam hauv tsev yuav tsum nrhiav kev ua haujlwm thev naus laus zis los rhuav tshem cov kev lag luam txawv teb chaws hauv cov khoom lag luam siab kawg.
(3) Kev hloov pauv ntawm tus nqi raw khoom
Refined paj rwb, lub ntsiab raw khoom ntawmcellulose ether, yog cov khoom siv ua liaj ua teb. Vim muaj kev hloov pauv hauv ib puag ncig ntuj, cov khoom tsim tawm thiab tus nqi yuav hloov pauv, uas yuav ua rau muaj kev nyuaj rau kev npaj cov khoom siv raw thiab kev tswj tus nqi ntawm kev lag luam downstream.
Tsis tas li ntawd, cov khoom siv petrochemical xws li propylene oxide thiab methyl chloride kuj tseem yog cov ntaub ntawv tseem ceeb rau kev tsim cov cellulose ether, thiab lawv cov nqi cuam tshuam zoo heev los ntawm kev hloov pauv hauv kev lag luam roj av. Cov kev hloov pauv hauv cov xwm txheej thoob ntiaj teb kev nom kev tswv feem ntau muaj kev cuam tshuam rau cov nqi roj av, yog li cov tuam txhab cellulose ether yuav tsum tau ntsib cov kev cuam tshuam tsis zoo ntawm kev hloov pauv ntawm cov nqi roj ntawm lawv cov khoom thiab kev ua haujlwm.
