Cellulose ether ndi mtundu wa zinthu zachilengedwe zochokera polima, zomwe zimakhala ndi emulsification ndi kuyimitsidwa. Pakati pa mitundu yambiri, HPMC ndi yomwe ili ndi mphamvu zambiri komanso yogwiritsidwa ntchito kwambiri, ndipo zotsatira zake zikuwonjezeka mofulumira.
M'zaka zaposachedwapa, chifukwa cha kukula kwa chuma cha dziko, kupanga ma cellulose ether m'dziko langa kwawonjezeka chaka ndi chaka. Pa nthawi yomweyi, ndi chitukuko cha sayansi ndi zamakono zapakhomo, ma ethers apamwamba a cellulose omwe poyamba ankafuna kuchuluka kwa katundu wochokera kunja tsopano akupezeka pang'onopang'ono, ndipo kuchuluka kwa katundu wa cellulose ethers kukupitiriza kuwonjezeka. Zambiri zikuwonetsa kuti kuyambira Januware mpaka Novembala 2020, kutumiza kunja kwa cellulose ether ku China kudafika matani 64,806, chiwonjezeko chapachaka cha 14.2%, chokwera kuposa kuchuluka kwa kunja kwa chaka chonse cha 2019.
Ma cellulose ether amakhudzidwa ndi mitengo ya thonje yokwera:
Zopangira zazikulu za cellulose ether zimaphatikizapo zinthu zaulimi ndi nkhalango kuphatikiza thonje woyengedwa ndi mankhwala kuphatikiza propylene oxide. Zopangira za thonje woyengedwa ndi thonje linters. dziko langa lili ndi thonje wochuluka wopanga, ndipo madera opangira ma linters a thonje amakhala makamaka ku Shandong, Xinjiang, Hebei, Jiangsu ndi malo ena. Zovala za thonje ndizochuluka kwambiri komanso zimapezeka zambiri.
Thonje amakhala ndi gawo lalikulu pazachuma chazaulimi, ndipo mtengo wake umakhudzidwa ndi zinthu zambiri monga chilengedwe komanso kupezeka ndi kufunidwa kwamayiko akunja. Momwemonso, mankhwala monga propylene oxide ndi methyl chloride amakhudzidwanso ndi mitengo yamafuta amafuta padziko lonse lapansi. Popeza kuti zopangira zimakhala ndi gawo lalikulu la mtengo wa cellulose ether, kusinthasintha kwamitengo yamafuta kumakhudza mwachindunji mtengo wamalonda wa cellulose ether.
Poyankha kukakamizidwa kwa mtengo, opanga mapadi a cellulose ether nthawi zambiri amasamutsa kukakamizidwa kupita kumakampani akumunsi, koma kutengerako kumakhudzidwa ndi zovuta zaukadaulo, kusiyanasiyana kwazinthu komanso mtengo wamtengo wowonjezera. Nthawi zambiri, mabizinesi omwe ali ndi zotchinga zapamwamba kwambiri, magulu olemera azinthu, komanso mtengo wowonjezera amakhala ndi zabwino zambiri, ndipo mabizinesi azikhala ndi phindu lokhazikika; Kupanda kutero, mabizinesi amayenera kukumana ndi chitsenderezo chokulirapo. Komanso, ngati chilengedwe chakunja ndi wosakhazikika ndi osiyanasiyana kusinthasintha mankhwala ndi lalikulu, kumtunda makampani zopangira ndi okonzeka kusankha kutsika makasitomala ndi sikelo yaikulu kupanga ndi amphamvu mabuku mphamvu kuonetsetsa phindu pa nthawi yake zachuma ndi kuchepetsa zoopsa. Chifukwa chake, izi zimalepheretsa kukula kwa mabizinesi ang'onoang'ono a cellulose ether kumlingo wina.
Kapangidwe ka Msika Wapansi:
Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, msika wofuna kutsika ukukula molingana. Panthawi imodzimodziyo, kuchuluka kwa mapulogalamu otsika pansi akuyembekezeredwa kuti apitirize kukula, ndipo kufunikira kwapansi pamtsinje kudzapitirizabe kukula. Pamsika wamsika wa cellulose ether, zida zomangira, kufufuza mafuta, chakudya ndi magawo ena amakhala ndi udindo waukulu. Pakati pawo, gawo lazomangamanga ndilo msika waukulu kwambiri wa ogula, wowerengera oposa 30%.
Makampani omanga ndi gawo lalikulu kwambiri lazinthu za HPMC:
M'makampani omanga, zinthu za HPMC zimagwira ntchito yofunika kwambiri pakumangirira ndi kusunga madzi. Pambuyo kusakaniza pang'ono HPMC ndi matope simenti, akhoza kuonjezera mamasukidwe akayendedwe, kumakoka ndi kukameta ubweya mphamvu ya simenti matope, matope, binder, etc., potero kupititsa patsogolo ntchito zomangira, kuwongolera zomangamanga ndi luso makina zomangamanga. Kuphatikiza apo, HPMC ndiyonso yolepheretsa kupanga ndi kutumiza konkire yamalonda, yomwe imatha kutseka madzi ndikuwonjezera kumveka kwa konkriti. Pakadali pano, HPMC ndiye chinthu chachikulu cha cellulose ether chomwe chimagwiritsidwa ntchito pomanga zida zosindikizira.
Ntchito yomanga ndi ntchito yofunika kwambiri pazachuma cha dziko langa. Deta ikuwonetsa kuti malo omanga omanga nyumba adakwera kuchokera pa 7.08 biliyoni masikweya mita mu 2010 mpaka 14.42 biliyoni masikweya mita mu 2019, zomwe zalimbikitsa kwambiri kukula kwa msika wa cellulose ether.
Kutukuka konse kwamakampani ogulitsa nyumba kwawonjezeka, ndipo malo omanga ndi ogulitsa akuwonjezeka chaka ndi chaka. Zambiri pagulu zikuwonetsa kuti mu 2020, kutsika kwapachaka kwa mwezi ndi mwezi m'malo atsopano omanga nyumba zamalonda kwakhala kukucheperachepera, ndipo kuchepa kwachaka kwakhala 1.87%. Mu 2021, njira yochira ikuyembekezeka kupitiliza. Kuyambira mu Januwale mpaka February chaka chino, kukula kwa malo ogulitsa nyumba zamalonda ndi nyumba zogonamo kunabwereranso ku 104.9%, zomwe zikuwonjezeka kwambiri.
Kuboola Mafuta:
Msika wamakampani opanga zobowola umakhudzidwa makamaka ndi kuwunika kwapadziko lonse lapansi ndi chitukuko, pafupifupi 40% ya ntchito zowunikira padziko lonse lapansi zomwe zimaperekedwa pantchito zauinjiniya.
Pobowola mafuta, madzi akubowola amatenga gawo lofunikira pakunyamula ndi kuyimitsa zodulidwa, kulimbitsa makoma a mabowo ndi kulimba kwa mapangidwe, kuziziritsa ndi zobowola mafuta, komanso kutumiza mphamvu ya hydrodynamic. Chifukwa chake, pantchito yoboola mafuta ndikofunikira kwambiri kukhalabe ndi chinyezi choyenera, kukhuthala, fluidity ndi zizindikiro zina zamadzimadzi obowola. Polyanionic cellulose, PAC, imatha kukhuthala, kuthira mafuta pobowola, ndikutumiza mphamvu ya hydrodynamic. Chifukwa cha zovuta za geological m'malo osungiramo mafuta komanso zovuta kubowola, pakufunika kwambiri PAC.
Makampani opangira mankhwala:
Nonionic cellulose ethers amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala monga mankhwala opangira mankhwala monga thickeners, dispersants, emulsifiers ndi opanga mafilimu. Izo ntchito ❖ kuyanika filimu ndi zomatira wa mapiritsi mankhwala, ndipo angagwiritsidwenso ntchito suspensions, mankhwala ophthalmic, mapiritsi akuyandama, etc. zovuta ndipo pali njira zambiri zochapira. Poyerekeza ndi magiredi ena a zinthu za cellulose ether, kuchuluka kwa zosonkhanitsira kumakhala kotsika ndipo mtengo wopangira ndi wokwera, koma mtengo wowonjezera wa mankhwalawo ndiwokwera. Zothandizira pazamankhwala zimagwiritsidwa ntchito kwambiri pokonzekera zinthu monga kukonzekera mankhwala, mankhwala a patent aku China ndi mankhwala am'chilengedwe.
Chifukwa chakumapeto kwa makampani opanga mankhwala m'dziko langa, chitukuko chonse chili chochepa, ndipo njira zamakampani ziyenera kukonzedwanso. Pakutulutsa kwamankhwala opangira mankhwala apakhomo, kuchuluka kwa mavalidwe amankhwala apanyumba kumakhala kochepa kwambiri kwa 2% mpaka 3%, komwe kumakhala kotsika kwambiri kuposa kuchuluka kwamankhwala akunja, komwe kuli pafupifupi 15%. Zitha kuwoneka kuti othandizira mankhwala apakhomo akadali ndi malo ambiri otukuka., Akuyembekezeka kulimbikitsa kukula kwa msika wokhudzana ndi cellulose ether.
Kuchokera pamalingaliro akupanga zoweta za cellulose ether, Shandong Head ili ndi mphamvu yayikulu yopanga, yowerengera 12.5% ya mphamvu zonse zopanga, ndikutsatiridwa ndi Shandong RUITAI, Shandong YITENG, North TIANPU Chemical ndi mabizinesi ena. Ponseponse, mpikisano wamakampaniwo ndi wowopsa, ndipo ndende ikuyembekezeka kuchulukirachulukira.
