Kodi msika wapansi wa cellulose ndi chiyani?

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 ndiye gawo lofunikira kwambiri pazinthu zachilengedwe za 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.

OKubowola

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 Prermaceutical

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 za mapiritsi opanga mankhwala, ndipo amathanso kugwiritsidwa ntchito poyimitsidwa, mapiritsi oyandama, ndi zina zopangidwa ndi mankhwalawa. 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 zopatsa mphamvu zapakhomo zimakhalabe ndi malo ambiri kuti zitheke, zikuyembekezeka kulimbikitsa kukula kwa msika wa elewel elel.

Kuchokera pakupanga kwa celluunt yapakhomo, mutu wa Shandong ali ndi mphamvu yayikulu kwambiri yopanga, yowerengera shandong ru ting, Shandong ru teng, North Tian Pun Chemical ndi Mabizinesi ena. Ponseponse, mpikisano mu malonda ndi wowopsa, ndipo kupsinjika kumayembekezeredwa.
