Cellulose ether ndi mtundu wa zinthu zachilengedwe zochokera ku polima, zomwe zimakhala ndi mawonekedwe a emulsification ndi suspension. Pakati pa mitundu yambiri, HPMC ndi yomwe ili ndi mphamvu yotulutsa kwambiri komanso yomwe imagwiritsidwa ntchito kwambiri, ndipo mphamvu yake ikuwonjezeka mofulumira.
M'zaka zaposachedwapa, chifukwa cha kukula kwa chuma cha dziko, kupanga kwa cellulose ether m'dziko langa kwawonjezeka chaka ndi chaka. Nthawi yomweyo, ndi chitukuko cha sayansi ndi ukadaulo wa m'dziko, ma cellulose ether apamwamba omwe poyamba ankafunika zinthu zambiri zotumizidwa kunja tsopano akuchulukirachulukira, ndipo kuchuluka kwa ma cellulose ether otumizidwa kunja kukupitirirabe. Deta ikuwonetsa kuti kuyambira Januwale mpaka Novembala 2020, kutumiza kwa cellulose ether ku China kunafika matani 64,806, kuwonjezeka kwa 14.2% pachaka, kuposa kuchuluka kwa kutumiza kunja kwa chaka chonse cha 2019.
Cellulose ether yakhudzidwa ndi mitengo ya thonje yomwe ikukwera：
Zipangizo zazikulu zopangira cellulose ether zimaphatikizapo zinthu zaulimi ndi nkhalango kuphatikiza thonje loyengedwa bwino ndi mankhwala kuphatikizapo propylene oxide. Zipangizo zopangira thonje loyengedwa bwino ndi thonje lopangidwa ndi thonje. Dziko langa lili ndi thonje lochuluka, ndipo madera opangira thonje lopangidwa ndi thonje ali makamaka ku Shandong, Xinjiang, Hebei, Jiangsu ndi malo ena. Thonje lopangidwa ndi thonje ndi lochuluka kwambiri ndipo likupezeka paliponse.
Thonje limakhala ndi gawo lalikulu kwambiri mu kapangidwe ka chuma cha ulimi, ndipo mtengo wake umakhudzidwa ndi zinthu zambiri monga zachilengedwe komanso kupezeka ndi kufunikira kwa mayiko. Mofananamo, zinthu za mankhwala monga propylene oxide ndi methyl chloride zimakhudzidwanso ndi mitengo ya mafuta osakonzedwa padziko lonse lapansi. Popeza zinthu zopangira zimakhala ndi gawo lalikulu mu kapangidwe ka mtengo wa cellulose ether, kusinthasintha kwa mitengo ya zinthu zopangira kumakhudza mwachindunji mtengo wogulitsa wa cellulose ether.
Poyankha kupsinjika kwa mtengo, opanga ma cellulose ether nthawi zambiri amasamutsa kupsinjika kupita ku mafakitale otsika mtengo, koma zotsatira zake zimakhudzidwa ndi zovuta za zinthu zaukadaulo, kusiyanasiyana kwa zinthu ndi mtengo wowonjezera wazinthu. Nthawi zambiri, mabizinesi omwe ali ndi zopinga zambiri zaukadaulo, magulu olemera azinthu, ndi mtengo wowonjezera wapamwamba amakhala ndi zabwino zambiri, ndipo mabizinesi azikhala ndi phindu lokhazikika; apo ayi, mabizinesi amafunika kukumana ndi kupsinjika kwakukulu kwa mtengo. Kuphatikiza apo, ngati malo akunja ndi osakhazikika ndipo kusinthasintha kwa zinthu kuli kwakukulu, makampani opanga zinthu zapamwamba amakhala ofunitsitsa kusankha makasitomala otsika mtengo okhala ndi kupanga kwakukulu komanso mphamvu zambiri kuti atsimikizire phindu lazachuma panthawi yake ndikuchepetsa zoopsa. Chifukwa chake, izi zimalepheretsa chitukuko cha mabizinesi ang'onoang'ono a cellulose ether mpaka pamlingo winawake.
Kapangidwe ka Msika Wotsika：
Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, msika wofunikira womwe ukutsikira udzakula moyenerera. Nthawi yomweyo, kuchuluka kwa ntchito zomwe zikutsikira kukuyembekezeka kupitiliza kukula, ndipo kufunikira komwe kukutsikira kudzakhalabe kokhazikika. Mu kapangidwe ka msika wa cellulose ether, zipangizo zomangira, kufufuza mafuta, chakudya ndi madera ena ali ndi malo akuluakulu. Pakati pawo, gawo la zipangizo zomangira ndilo msika waukulu kwambiri wa ogula, womwe uli ndi oposa 30%.
Makampani omanga ndi gawo lalikulu kwambiri la ogula zinthu za HPMC：
Mu makampani omanga, zinthu za HPMC zimagwira ntchito yofunika kwambiri pakumanga ndi kusunga madzi. Mukasakaniza HPMC pang'ono ndi simenti, zimatha kuwonjezera kukhuthala, mphamvu yokoka ndi kumeta kwa simenti, simenti, binder, ndi zina zotero, motero zimathandizira magwiridwe antchito a zipangizo zomangira, kukonza ubwino wa zomangamanga komanso kugwira ntchito bwino kwa makina omangira. Kuphatikiza apo, HPMC ndi chida chofunikira kwambiri popanga ndi kunyamula simenti yogulitsa, chomwe chingatseke madzi ndikuwonjezera kusinthasintha kwa simenti. Pakadali pano, HPMC ndiye chinthu chachikulu cha cellulose ether chomwe chimagwiritsidwa ntchito popanga zinthu zomangira.
Makampani omanga ndi mizati yofunika kwambiri pa chuma cha dziko langa. Deta ikuwonetsa kuti malo omanga nyumba awonjezeka kuchoka pa 7.08 biliyoni mita za sikweya mu 2010 kufika pa 14.42 biliyoni mita za sikweya mu 2019, zomwe zalimbikitsa kwambiri kukula kwa msika wa cellulose ether.
Kupita patsogolo kwa makampani ogulitsa nyumba kwakweranso, ndipo malo omanga ndi ogulitsa awonjezeka chaka ndi chaka. Deta ya anthu onse ikuwonetsa kuti mu 2020, kuchepa kwa mwezi uliwonse kwa malo atsopano omanga nyumba zamalonda kwachepa, ndipo kuchepa kwa chaka ndi chaka kwakhala 1.87%. Mu 2021, kuyambiranso kwachuma kukuyembekezeka kupitirira. Kuyambira Januwale mpaka Febuluwale chaka chino, kuchuluka kwa malo ogulitsa nyumba zamalonda ndi nyumba zogona kwakweranso kufika pa 104.9%, zomwe ndi kuwonjezeka kwakukulu.
Kubowola Mafuta:
Msika wamakampani opanga ntchito zaukadaulo wobowola umakhudzidwa makamaka ndi ndalama zofufuzira ndi chitukuko padziko lonse lapansi, ndipo pafupifupi 40% ya ndalama zonse zofufuzira padziko lonse lapansi zimaperekedwa ku ntchito zaukadaulo wobowola.
Pakuboola mafuta, madzi oboola amachita gawo lofunika kwambiri pakunyamula ndi kuyimitsa zidutswa, kulimbitsa makoma a mabowo ndi kulimbitsa mphamvu yopangira, kuziziritsa ndi kudzola zidutswa za kuboola, komanso kutumiza mphamvu ya hydrodynamic. Chifukwa chake, pantchito yoboola mafuta, ndikofunikira kwambiri kusunga chinyezi choyenera, kukhuthala, kusinthasintha ndi zizindikiro zina za madzi oboola. Polyanionic cellulose, PAC, imatha kukhuthala, kudzola mafuta a boola, ndikutumiza mphamvu ya hydrodynamic. Chifukwa cha zovuta za geological m'malo osungira mafuta komanso zovuta zoboola, pali kufunikira kwakukulu kwa PAC.
Makampani opangira zida zamankhwala:
Ma ether a cellulose omwe si a ionic amagwiritsidwa ntchito kwambiri mumakampani opanga mankhwala monga zinthu zothina, zothina, zosakaniza, ndi zopanga filimu. Amagwiritsidwa ntchito popaka filimu ndi zomatira pamapiritsi a mankhwala, ndipo angagwiritsidwenso ntchito poyimitsa, kukonza maso, mapiritsi oyandama, ndi zina zotero. Popeza ether ya cellulose ya mankhwala ili ndi zofunikira kwambiri pa kuyera ndi kukhuthala kwa chinthucho, njira yopangira ndi yovuta kwambiri ndipo pali njira zambiri zotsukira. Poyerekeza ndi mitundu ina ya zinthu za cellulose ether, mtengo wosonkhanitsira ndi wotsika ndipo mtengo wopangira ndi wokwera, koma mtengo wowonjezera wa chinthucho ndi wokweranso. Zinthu zothina zamankhwala zimagwiritsidwa ntchito makamaka popanga zinthu monga mankhwala okonzekera, mankhwala a patent aku China ndi zinthu za biochemical.
Chifukwa cha kuyamba mochedwa kwa makampani opanga mankhwala mdziko langa, kuchuluka kwa chitukuko komwe kukuchitika pakadali pano kuli kotsika, ndipo njira yogwirira ntchito yamakampaniyi ikufunika kukonzedwanso. Mu mtengo wopangidwa ndi mankhwala apakhomo, mtengo wopangidwa ndi zodzoladzola zamankhwala apakhomo ndi wochepa kwambiri wa 2% mpaka 3%, womwe ndi wocheperako poyerekeza ndi kuchuluka kwa mankhwala akunja, omwe ndi pafupifupi 15%. Zikuoneka kuti mankhwala apakhomo akadali ndi malo ambiri oti apangidwe. Akuyembekezeka kulimbikitsa bwino kukula kwa msika wogwirizana wa cellulose ether.
Poganizira za kupanga ether ya cellulose m'nyumba, Shandong Head ili ndi mphamvu zambiri zopangira, zomwe zimapangitsa kuti ikhale 12.5% ya mphamvu zonse zopangira, kutsatiridwa ndi Shandong RUITAI, Shandong YITENG, North TIANPU Chemical ndi mabizinesi ena. Ponseponse, mpikisano mumakampani ndi woopsa, ndipo kuchuluka kwa anthu omwe akuyembekezeka kukwera kwambiri.
