Ma cellulose ether: zida zopangira kumtunda zimakhala ndi mphamvu yayikulu, ndipo msika wakumunsi ukukula.
Ma cellulose ether ndi mtundu wa zinthu zachilengedwe zochokera ku polima, zomwe zimakhala ndi emulsification ndi kuyimitsidwa.Mumitundu yambiri, hydroxypropyl methyl cellulose ether yomwe ndi HPMC ndiyo yokolola kwambiri, yomwe imagwiritsidwa ntchito kwambiri, kupanga kwake kukuchulukirachulukira.
M'zaka zaposachedwa, kupindula ndi kukula kwachuma cha dziko, kupanga ma cellulose ether a dziko lathu kumakwera chaka ndi chaka.Pa nthawi yomweyi, ndi chitukuko cha sayansi ndi zamakono zapakhomo, kufunikira koyambirira kuitanitsa chiwerengero chachikulu cha ether chapamwamba cha cellulose tsopano chimazindikira pang'onopang'ono kutanthauzira, ndipo kutumiza kunja kwa cellulose ether yapakhomo ikukwera.Zambiri zikuwonetsa kuti kuyambira Januware mpaka Novembala 2020, China idatumiza matani 64,806 a cellulose ether, kukwera ndi 14.2% chaka chilichonse, kuposa chaka chonse cha 2019.

Ma cellulose ether omwe akhudzidwa ndi mitengo ya thonje yokwera
Zopangira zazikulu zama cellulose ethers zimaphatikizapo zinthu zaulimi ndi nkhalango, kuphatikiza thonje woyengedwa, ndi mankhwala, kuphatikiza propylene oxide.Zopangira za thonje woyengedwa ndi thonje lalifupi la cashmere, ndipo thonje lalifupi la cashmere limapangidwa makamaka ku Shandong, Xinjiang, Hebei ndi Jiangsu.Gwero la ubweya wa thonje ndi wochuluka kwambiri komanso wokwanira.
Thonje ndi gawo lalikulu pazachuma zaulimi wamalonda, ndipo mtengo wake umakhudzidwa ndi chilengedwe komanso kufunikira kwa mayiko.Momwemonso, propylene oxide, chloromethane ndi mankhwala ena amakhudzidwanso ndi mitengo yamafuta padziko lonse lapansi.Popeza kuti zopangira zimakhala ndi gawo lalikulu la mtengo wa cellulose ether, kusinthasintha kwa mtengo wamtengo wapatali kumakhudza mwachindunji mtengo wogulitsa wa cellulose ether.
Pofuna kuthana ndi kupanikizika kwa mtengo, opanga mapadi a cellulose ether nthawi zambiri amasamutsa kukakamizidwa kumakampani akumunsi, koma kutengerako kumakhudzidwa ndi zovuta zaukadaulo, kusiyanasiyana kwazinthu komanso kuchuluka kwa mtengo wazinthu ndi mtengo wowonjezera.Nthawi zambiri, mabizinesi omwe ali ndi zotchinga zaukadaulo, magulu olemera azinthu komanso mtengo wowonjezera amakhala ndi zabwino zambiri ndipo amakhalabe ndi phindu lokhazikika.Kupanda kutero, mabizinesi amayenera kukumana ndi zovuta zotsika mtengo.Komanso, ngati chilengedwe kunja ndi wosakhazikika ndi osiyanasiyana kusinthasintha mankhwala ndi lalikulu, kumtunda mabizinezi yaiwisi ndi wokonzeka kusankha makasitomala kunsi kwa mtsinje ndi lalikulu kupanga sikelo ndi amphamvu mabuku mphamvu, kuti kuonetsetsa kuti nthawi yake phindu zachuma ndi kuchepetsa zoopsa.Chifukwa chake, izi zimalepheretsa kukula kwa mabizinesi ang'onoang'ono a cellulose ether kumlingo wina.
Ma cellulose ether ndi mtundu wa zinthu zachilengedwe zochokera ku polima, zomwe zimakhala ndi emulsification ndi kuyimitsidwa.Mumitundu yambiri, hydroxypropyl methyl cellulose ether yomwe ndi HPMC ndiyo yokolola kwambiri, yomwe imagwiritsidwa ntchito kwambiri, kupanga kwake kukuchulukirachulukira.
Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, msika wofuna kutsika ukukulirakulira, ndipo kuchuluka kwa ntchito zotsika kukuyembekezeka kukulirakulira mosalekeza, ndipo kufunikira kwakutsika kukukulirakulira.Mumsika wakumunsi wamsika wa cellulose ether, zida zomangira, kuchotsa 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, kusunga madzi ndi zotsatira zina.Pambuyo kusakaniza pang'ono HPMC ndi matope simenti, mamasukidwe akayendedwe, kukokera ndi kukameta ubweya mphamvu ya simenti matope, matope ndi binder akhoza ziwonjezeke, kuti patsogolo ntchito zipangizo zomangira, kusintha khalidwe la zomangamanga ndi makina zomangamanga Mwachangu.Kuphatikiza apo, HPMC ndiyonso yolepheretsa kupanga ndi kunyamula konkire yamalonda, yomwe imathandizira kutseka kwamadzi ndikukulitsa mawonekedwe a konkriti.Pakadali pano, HPMC ndiye chinthu chofunikira kwambiri cha cellulose ether chomwe chimagwiritsidwa ntchito pomanga zida zosindikizira.
Makampani omanga ndi gawo lalikulu lazachuma cha dziko lathu.Zambiri zikuwonetsa kuti malo omanga nyumba adakwera kuchokera pa 7.08 biliyoni masikweya mita mu 2010 mpaka 14.42 biliyoni masikweya mita mu 2019, ndikuyendetsa kwambiri kukula kwa msika wa cellulose ether.
Kukula kwakukulu kwamakampani ogulitsa nyumba kudayamba, ndipo malo omanga ndi kugulitsa adakwera chaka ndi chaka.Zambiri zapagulu zikuwonetsa kuti mu 2020, kutsika kwapachaka kwapachaka m'malo atsopano omanga nyumba zamalonda kukupitilirabe, kutsika ndi 1.87% pachaka, 2021 ikuyembekezeka kupitiliza kukonza.M'miyezi iwiri yoyambirira ya chaka chino, chiwopsezo cha kukula kwa malo okhala nyumba zamalonda chinabwereranso ku 104.9%, kuwonjezeka kolemekezeka.
Kubowola mafuta
Msika wamakampani opanga zobowola umakhudzidwa makamaka ndi ndalama zapadziko lonse lapansi za E&P, pomwe pafupifupi 40% ya ntchito zowunikira padziko lonse lapansi zimaperekedwa pantchito zauinjiniya.
Pakubowola ndi kupanga mafuta, madzi akubowola amatenga gawo lofunikira pakunyamula ndi kuyimitsa tchipisi, kulimbitsa makoma a mabowo ndikuwongolera kukakamiza kwa mapangidwe, kuziziritsa ndi kupaka mafuta pang'ono, komanso kusamutsa mphamvu za hydrodynamic.Choncho, pobowola mafuta, ndikofunikira kwambiri kusunga chinyezi choyenera, kukhuthala, fluidity ndi zizindikiro zina zamadzimadzi obowola.Polyanionic cellulose, kapena PAC, imatha kukhuthala, kuthira mafuta pang'ono, ndikusintha mphamvu za hydrodynamic.Chifukwa cha zovuta za geological za malo osungiramo mafuta komanso kuvuta kubowola, pali kuchuluka kwakukulu kwa PAC yogwiritsa ntchito.
Makampani opangira mankhwala
Ma cellulose ethers omwe si a ionic amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala monga mankhwala opangira mankhwala, monga thickeners, dispersants, emulsifiers ndi opanga mafilimu.Amagwiritsidwa ntchito popaka filimu ndi zomatira pamapiritsi amankhwala, komanso angagwiritsidwe ntchito poyimitsa, kukonzekera maso, mapiritsi oyandama ndi zina zotero.Chifukwa cha zofunika kwambiri pa chiyero ndi mamasukidwe akayendedwe a mankhwala cellulose ether mankhwala, njira kupanga ndi zovuta kwambiri ndipo ndondomeko kuchapa ndi zovuta kwambiri.Poyerekeza ndi zinthu zina zama cellulose ether, mtengo wosonkhanitsira ndi wotsika, mtengo wopangira ndi wokwera, koma mtengo wowonjezera wamafuta ndiwokwera.Ma excipients amankhwala amagwiritsidwa ntchito kwambiri popanga mankhwala, mankhwala a patent aku China, mankhwala achilengedwe ndi biochemical ndi zinthu zina zamankhwala.
Chifukwa makampani othandizira mankhwala adayamba mochedwa, kukula kwachitukuko ndi kotsika pakadali pano, makina amakampani akuyenera kukonzedwanso.Pakati pa linanena bungwe mtengo wa mankhwala zoweta mankhwala, linanena bungwe mtengo wa zoweta mankhwala mavalidwe nkhani ndi otsika gawo la 2% -3%, amene ndi otsika kwambiri kuposa excipients mankhwala achilendo (pafupifupi 15%).Zitha kuwoneka kuti pakadali malo abwino opangira zopangira mankhwala apakhomo, zomwe zikuyembekezeka kuyendetsa bwino msika wa cellulose ether.
