Cellulose ether yog ib yam ntawm cov khoom siv ntuj tsim los ntawm polymer, uas muaj cov yam ntxwv ntawm emulsification thiab ncua kev kawm ntawv. Ntawm ntau hom, HPMC yog ib qho uas muaj qhov tso zis ntau tshaj plaws thiab siv dav tshaj plaws, thiab nws cov zis tau nce sai.
Nyob rau hauv xyoo tas los no, ua tsaug rau kev loj hlob ntawm kev lag luam hauv teb chaws, kev tsim cov cellulose ether hauv kuv lub teb chaws tau nce xyoo los ntawm xyoo. Nyob rau tib lub sij hawm, nrog rau kev loj hlob ntawm domestic science thiab technology, high-end cellulose ethers uas Ameslikas xav tau ib tug loj npaum li cas ntawm imports tam sim no maj localized, thiab export ntim ntawm domestic cellulose ethers tseem nce. Cov ntaub ntawv qhia tau hais tias txij Lub Ib Hlis Ntuj txog Lub Kaum Ib Hlis 2020, Tuam Tshoj cov cellulose ether xa tawm mus txog 64,806 tons, ib xyoos ib zaug nce ntawm 14.2%, siab dua li cov khoom xa tawm tag nrho ntawm 2019.
Cellulose ether cuam tshuam los ntawm cov nqi paj rwb:
Cov khoom siv tseem ceeb ntawm cellulose ether suav nrog cov khoom ua liaj ua teb thiab hav zoov suav nrog cov paj rwb zoo thiab cov khoom siv tshuaj xws li propylene oxide. Cov khoom siv ntawm cov paj rwb refined yog paj rwb linters. kuv lub teb chaws muaj ntau cov paj rwb ntau lawm, thiab cov chaw tsim khoom ntawm paj rwb linters feem ntau yog nyob rau hauv Shandong, Xinjiang, Hebei, Jiangsu thiab lwm qhov chaw. Cov paj rwb linters yog plentiful thiab nyob rau hauv plentiful mov.
Paj rwb occupies ib tug kuj loj feem nyob rau hauv cov khoom ua liaj ua teb kev lag luam qauv, thiab nws cov nqi yog cuam tshuam los ntawm ntau yam xws li tej yam ntuj tso tej yam kev mob thiab thoob ntiaj teb mov thiab kev thov. Ib yam li ntawd, cov khoom siv tshuaj xws li propylene oxide thiab methyl chloride kuj raug cuam tshuam los ntawm cov nqi roj av thoob ntiaj teb. Txij li cov khoom siv raw suav nrog ntau qhov kev faib ua feem ntawm tus nqi ntawm cellulose ether, kev hloov pauv ntawm cov khoom siv raw khoom ncaj qha cuam tshuam rau tus nqi muag ntawm cellulose ether.
Nyob rau hauv teb rau cov nqi siab, cellulose ether manufacturers feem ntau hloov lub siab mus rau downstream industries, tab sis cov kev hloov pauv tau cuam tshuam los ntawm cov complexity ntawm technical cov khoom, ntau yam khoom thiab cov khoom nqi ntxiv tus nqi. Feem ntau, cov tuam txhab lag luam uas muaj kev cuam tshuam kev lag luam siab, cov khoom lag luam nplua nuj, thiab cov nqi ntxiv muaj txiaj ntsig zoo dua, thiab cov tuam txhab lag luam yuav tswj hwm qib qis ntawm cov txiaj ntsig tag nrho; txwv tsis pub, cov lag luam yuav tsum tau ntsib tus nqi siab dua. Tsis tas li ntawd, yog tias qhov chaw sab nraud tsis ruaj khov thiab qhov ntau ntawm cov khoom hloov pauv loj, cov tuam txhab cov khoom siv raw khoom tau txaus siab xaiv cov neeg siv khoom qis nrog cov khoom loj thiab muaj zog ua tiav kom ntseeg tau cov txiaj ntsig kev lag luam raws sij hawm thiab txo cov kev pheej hmoo. Yog li ntawd, qhov no txwv txoj kev loj hlob ntawm me me cellulose ether tuam txhab rau ib tug tej yam uas.
Downstream Market Structure:
Nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, kev lag luam qis qis yuav loj hlob raws li. Nyob rau tib lub sijhawm, cov peev txheej ntawm cov ntawv thov hauv qab yuav tsum tau nthuav dav ntxiv, thiab cov kev xav tau qis qis yuav tswj kev loj hlob tsis tu ncua. Hauv kev lag luam downstream qauv ntawm cellulose ether, cov khoom siv hauv tsev, kev tshawb nrhiav roj, zaub mov thiab lwm yam kev lag luam nyob hauv txoj haujlwm tseem ceeb. Ntawm lawv, cov khoom siv hauv tsev yog cov neeg siv khoom lag luam loj tshaj plaws, suav txog ntau dua 30%.
Kev tsim kho kev lag luam yog cov neeg siv khoom loj tshaj plaws ntawm HPMC cov khoom:
Hauv kev tsim kho kev lag luam, HPMC cov khoom lag luam ua lub luag haujlwm tseem ceeb hauv kev sib txuas thiab tuav dej. Tom qab sib tov ib qho me me ntawm HPMC nrog cov cement mortar, nws tuaj yeem ua kom cov viscosity, tensile thiab shear zog ntawm cov cement mortar, mortar, binder, thiab lwm yam, yog li txhim kho kev ua tau zoo ntawm cov khoom siv hauv tsev, txhim kho kev tsim kho thiab kev tsim kho tshuab. Tsis tas li ntawd, HPMC tseem yog ib qho tseem ceeb retarder rau kev tsim khoom thiab kev thauj mus los ntawm kev lag luam pob zeb, uas tuaj yeem kaw dej thiab txhim kho rheology ntawm pob zeb. Tam sim no, HPMC yog lub ntsiab cellulose ether cov khoom siv hauv tsev cov ntaub ntawv sib khi.
Kev tsim kho kev lag luam yog ib qho kev lag luam tseem ceeb ntawm kuv lub teb chaws kev lag luam. Cov ntaub ntawv qhia tau hais tias thaj tsam ntawm kev tsim vaj tsev nyob tau nce los ntawm 7.08 billion square metres hauv 2010 txog 14.42 billion square meters hauv 2019, uas tau txhawb nqa kev loj hlob ntawm cellulose ether kev lag luam.
Tag nrho txoj kev vam meej ntawm kev lag luam vaj tse tau rov zoo, thiab kev tsim kho thiab kev muag khoom tau nce xyoo ib xyoos. Cov ntaub ntawv pej xeem qhia tau hais tias xyoo 2020, kev poob qis hauv ib lub hlis ntawm xyoo ntawm kev tsim kho tshiab ntawm cov vaj tsev nyob hauv kev lag luam tau nqaim, thiab kev txo qis xyoo ib xyoos yog 1.87%. Hauv xyoo 2021, qhov kev rov qab los xav tias yuav txuas ntxiv mus. Txij lub Ib Hlis mus txog Lub Ob Hlis xyoo no, qhov kev loj hlob ntawm thaj chaw muag khoom ntawm cov vaj tsev ua lag luam thiab cov tsev nyob tau rov qab mus rau 104.9%, uas yog qhov nce ntau.
Roj Drilling:
Kev lag luam kev lag luam kev lag luam yog qhov cuam tshuam tshwj xeeb los ntawm kev tshawb nrhiav thiab kev tsim kho thoob ntiaj teb, nrog kwv yees li 40% ntawm kev tshawb nrhiav thoob ntiaj teb tau mob siab rau cov kev pabcuam drilling engineering.
Thaum lub sij hawm roj drilling, drilling kua ua lub luag haujlwm tseem ceeb hauv kev nqa thiab tshem tawm cov txiav, ntxiv dag zog lub qhov phab ntsa thiab ntsuas qhov tsim siab, txias thiab lubricating laum khoom, thiab xa cov quab yuam hydrodynamic. Yog li ntawd, nyob rau hauv cov roj drilling ua hauj lwm, nws yog ib qho tseem ceeb heev kom muaj cov av noo, viscosity, fluidity thiab lwm yam kev ntsuas ntawm drilling kua. Lub polyanionic cellulose, PAC, tuaj yeem ua kom tuab, lubricate lub laum me ntsis, thiab xa cov zog hydrodynamic. Vim yog qhov nyuaj geological tej yam kev mob nyob rau hauv cov roj cia cheeb tsam thiab qhov nyuaj ntawm drilling, muaj ib tug loj thov rau PAC.
Pharmaceutical accessories kev lag luam:
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 zaj duab xis qub. Nws yog siv rau zaj duab xis txheej thiab nplaum ntawm cov tshuaj ntsiav tshuaj, thiab kuj yuav siv tau rau ncua kev kawm ntawv, ophthalmic npaj, floating ntsiav tshuaj, thiab lwm yam. Txij li thaum cov tshuaj qib cellulose ether muaj stricter yuav tsum tau rau lub purity thiab viscosity ntawm cov khoom, cov txheej txheem raug kuj. nyuaj thiab muaj ntau cov txheej txheem ntxuav. Piv nrog rau lwm qib ntawm cov khoom lag luam cellulose ether, tus nqi sau qis dua thiab cov nqi tsim khoom ntau dua, tab sis tus nqi ntxiv ntawm cov khoom kuj tseem siab dua. Pharmaceutical excipients feem ntau yog siv rau hauv kev npaj cov khoom xws li tshuaj npaj, suav tshuaj patent thiab biochemical khoom.
Vim qhov pib lig ntawm kuv lub teb chaws cov tshuaj excipients kev lag luam, tam sim no tag nrho cov kev loj hlob theem yog tsawg, thiab kev lag luam mechanism yuav tsum tau txhim kho ntxiv. Nyob rau hauv cov khoom tsim tawm tus nqi ntawm kev npaj tshuaj hauv tsev, tus nqi tsim tawm ntawm cov khoom siv tshuaj kho mob hauv tsev muaj feem tsawg ntawm 2% mus rau 3%, uas yog qis dua qhov feem pua ntawm cov tshuaj txawv teb chaws, uas yog kwv yees li 15%. Nws tuaj yeem pom tau tias cov khoom siv tshuaj hauv tsev tseem muaj ntau chav rau kev txhim kho., Nws xav tias yuav ua kom muaj txiaj ntsig zoo rau kev loj hlob ntawm kev lag luam cellulose ether.
Los ntawm qhov kev xav ntawm domestic cellulose ether ntau lawm, Shandong Lub taub hau muaj peev xwm ntau tshaj plaws, suav txog 12.5% ntawm tag nrho cov peev txheej, ua raws li Shandong RUITAI, Shandong YITENG, North TIANPU Tshuaj thiab lwm yam lag luam. Zuag qhia tag nrho, kev sib tw hauv kev lag luam yog qhov hnyav, thiab kev xav tias yuav tsum nce ntxiv.
