Cellulose ether ndi mtundu wa zinthu zachilengedwe zochokera polima, zomwe zili ndi mawonekedwe a emulsization ndi kuyimitsidwa. Mwa mitundu yambiri, hpmc ndi omwe ali ndi zotulutsa zapamwamba kwambiri komanso zomwe zimagwiritsidwa ntchito kwambiri, ndipo zotulutsa zake zikuwonjezeka mwachangu.
M'zaka zaposachedwa, chifukwa cha kukula kwa chuma cha dziko lonse lapansi, kupanga ma cellulose m'dziko langa kwakwera chaka ndi chaka. Nthawi yomweyo, ndikukula kwa sayansi yam'nyumba ndi ukadaulo, ma cellose-a cellulose othamanga omwe poyambirira amafunikira kuti zinthu zambiri zizigwiritsidwa ntchito pang'onopang'ono, komanso kuchuluka kwa ma cellulose omwe akupitilirabe. Zambiri zikuwonetsa kuti kuyambira Januwale mpaka Novembara 2020, Ethel Eleul Exent idafikira matani 64,806, kuchuluka kwa chaka chimodzi.
Cellulose ether imakhudzidwa ndi mitengo ya thonje ya thonje:
Zida zazikulu za cellulose ether ether ethermit ndi zopangidwa ndi nkhalango kuphatikizapo thonje loyenga ndi mankhwala kuphatikiza ma problene oxide. Zinthu zotsekereza za thonje loyengeka ndi mabatire a thonje. Dziko langa lili ndi mafuta a thonje, ndipo madera opangira ma thonje amakhazikika ku Shandong, Xinjiang, Hebei, Jiangsu ndi malo ena. Maukadaulo a thonje ndi ochuluka kwambiri komanso amapeza zambiri.
Thonjeni limakhala ndi gawo lalikulu mu katundu wazomwe alilimi, ndipo mtengo wake umakhudzidwa ndi zinthu zambiri monga momwe zinthu zilili ndi zinthu zina. Momwemonso, zinthu zamankhwala monga Propylene oxide ndi methyl chloride imakhudzidwanso ndi mitengo yamafuta yapadziko lonse lapansi. Popeza akaunti ya raw ya gawo lalikulu pamtengo wokwera mtengo wa ethel ether, kusinthasintha kwa mitengo yaiwisi kumakhudza mtengo wogulitsa wa cellulose.
Poyankha zotsika mtengo, ma cellulose equir opanga nthawi zambiri amasamutsa mafakitale otsika, koma kusintha komwe kumakhudzidwa ndi zovuta zomwe zimakhudzidwa ndi zinthu zaukadaulo, zosiyanasiyana ndi mtengo wake mtengo wowonjezereka. Nthawi zambiri, mabizinesi okhala ndi zotchinga zapamwamba, magulu olemera, komanso phindu lalikulu lili ndi zabwino zambiri, ndipo mabizinesi amakhala ndi phindu lalikulu; Kupanda kutero, mabizinesi amafunika kuthana ndi mavuto ambiri. Kuphatikiza apo, ngati malo akunja ndi osakhazikika ndipo makampani osiyanasiyana, makampani othamanga amakhala ofunitsitsa kusankha makasitomala omwe ali ndi makasitomala akuluakulu opangira nthawi kuti athandize pazachuma nthawi yake ndikuchepetsa ngozi. Chifukwa chake, izi zimatha kukula kwa mabizinesi a cellose a cellose mpaka pamlingo wina.
Kugwa kwa Msika:
Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, msika wotsika mtengo umakula. Nthawi yomweyo, kuchuluka kwa mapulogalamu akuyembekezeredwa kuti apitilize kukula, ndipo kumafuna kukulira kosasunthika. Pamsika wapansi pa cellulose ether, zopangira zomangira, kufufuza kwamafuta, chakudya ndi minda zina zimakhala pamalo akulu. Pakati pawo, zopangira nyumbayo ndi msika wa ogula kwambiri, amawerengera zoposa 30%.
Makampani opanga nyumba ndiye gawo lalikulu kwambiri lazogulitsa za HPMC:
M'makampani omanga, zinthu za HPMC zimagwira ntchito yofunika kwambiri polumikizana komanso kusungidwa kwamadzi. Nditasakanikirana pang'ono ndi matope a simenti, imatha kuwonjezera matope, kusokonekera kwa matope a simenti, matontho, ndi zina zambiri. Kuphatikiza apo, HPMC ndi yofunikanso yobwezera konkriti ndi mayendedwe azamalonda, omwe amatha kutseka madzi ndikuwonjezera rhelogy ya konkriti. Pakadali pano, HPMC ndiye chinthu chachikulu kwambiri cha embi chomwe chimagwiritsidwa ntchito pomanga zida zosindikizira.
Makampani opanga nyumba ndi malo opangira mapiritsi am dziko la dziko langa. Zambiri zikuwonetsa kuti malo omanga nyumba achulukana kuchokera ku mabizinesi a 7.08 biliyoni mu 2010 mpaka 14.42 Biliyoni Square Metres mu 2019, yomwe yalimbikitsa kwambiri kukula kwa msika wa elelul.
Kupambana konse kwa makampani enieni ogulitsa katundu akubweranso, ndipo malo omanga ndi ogulitsa akwera chaka ndi chaka. Zambiri za anthu zikuwonetsa kuti mu 2020, kuchepa kwa chaka cha pamwezi mu gawo latsopano lanyumba zomanga zamalonda kwakhala kuchepa, ndipo kuchepa kwa chaka kwa chaka kwakhala 1.87%. Mu 2021, zomwe zikuchitika zikuyembekezeka kupitiliza. Kuyambira Januwale mpaka mu February chaka chino, kuchuluka kwa malo ogulitsa nyumba zamalonda komanso nyumba zokhalamo zobwezeretsanso mpaka 104.9%, komwe kumawonjezeka.
Kubowola Mafuta:
Msika wogulitsa zamalonda umakhudzidwa kwambiri ndi kupenda dziko lonse komanso chitukuko chogulitsa, pafupifupi 40% ya kupendapondapo kwapadziko lonse komwe akuwonetsa kuti aborere ntchito zomangamanga.
Pa nthawi yamafuta amabowola, madzimadzi amasewera gawo lofunikira pakunyamula ndi kuyimitsa madabwa, kulimbikitsa makoma a mapangidwe a mafoloko, ndikupatsirana ma bits ofunda, ndikupatsira mphamvu hydrodynamic mphamvu. Chifukwa chake, mu ntchito yoboola mafuta, ndikofunikira kwambiri kukhala ndi chilengedwe choyenera, mafakisoni, madzi ndi zisonyezo zina zomwe zimabowola zamadzimadzi. Cellulose ya Polyunionic, Pac, imatha kunenepa, mafuta obowola pang'ono, ndikupereka hydrodynamic mphamvu. Chifukwa cha zovuta zamikhalidwe m'malo osungirako mafuta komanso zovuta zobowola, pamakhala kufunikira kwakukulu kwa Pac.
Mafakitale a Mankhwala:
Cellulose yopanda tanthauzo imagwiritsidwa ntchito kwambiri m'makampani opangira mankhwala monga mankhwala ophatikizira monga obaya, osamwa, ma emulsifiers ndi fomu ya film. Amagwiritsidwa ntchito ngati filimu komanso zomatira zomata za mapiritsi a mankhwala, ndipo amathanso kugwiritsidwa ntchito poimikapo, mapiritsi oyandama, ndi zina zopangidwa ndi mankhwalawa Zovuta ndipo pali njira zotsukira. Poyerekeza ndi magulu ena a ethel ethel, mtengo wosungirako ndi wotsika ndipo mtengo wopanga ndiwokwera, koma mtengo wowonjezera wazomwezo ndiwokweranso. Zosangalatsa za mankhwala zimagwiritsidwa ntchito makamaka pokonzekera kukonzekera kwamankhwala monga kukonzekera kwamankhwala, kutchalitchi cha China Medics ndi zinthu za biocherical.
Chifukwa chakumapeto kwa mafakitale a dziko langa la mankhwala ophatikizira, kuchuluka kwa chitukuko chaposachedwa kuli kochepa, ndipo makina amafunikanso kupitilizidwa. Mu mtengo wobweretsa mankhwala opanga mankhwala opanga mankhwala, mtengo wotulutsa wanyumba yamankhwala pazinthu zosafunikira 2% mpaka 3%, zomwe zimakhala ndi 15%. Itha kuwoneka kuti zothandizira zazomwe zimapezekabe ndi malo ambiri kuti zikhalebe.
Kuchokera pakupanga kwa celluunt yapakhomo, mutu wa Shandong ali ndi mphamvu yayikulu kwambiri yopanga, yowerengera Shandong Ruitai, Shandong Yiting, North Tiacka mankhwala ndi mabizinesi ena. Ponseponse, mpikisano mu malonda ndi wowopsa, ndipo kupsinjika kumayembekezeredwa.
