Cellulose ether: kumusoro kwemvura mbishi zvinhu zvine simba rakakura, uye musika wepasi uri kukura.
Cellulose ether rudzi rwechisikigo chepolymer chakatorwa, icho chine emulsification uye kumiswa hunhu. Mumhando dzakawanda, hydroxypropyl methyl cellulose ether iri HPMC ndiyo goho repamusoro, iro rinonyanya kushandiswa, kugadzirwa kwayo kuri kuwedzera nekukurumidza.
Mumakore achangopfuura, tichibatsirwa nekukura kwehupfumi hwenyika, kugadzirwa kwe cellulose ether yenyika yedu inokwira gore negore. Panguva imwecheteyo, nekuvandudzwa kwesainzi yemumba uye tekinoroji, kudiwa kwepakutanga kupinza nhamba huru ye-high-end cellulose ether ikozvino zvishoma nezvishoma inoona nzvimbo, uye kunze kwenyika cellulose ether iri kuwedzera. Data inoratidza kuti kubva muna Ndira kusvika Mbudzi 2020, China yakatumira kunze 64,806 matani e-cellulose ether, yakakwira 14.2% gore negore, yakakwira kupfuura iyo yese ye2019.

Cellulose ether yakakanganiswa nemitengo yedonje iri kumusoro
Zvigadzirwa zvikuru zve cellulose ethers zvinosanganisira zvigadzirwa zvekurima nemasango, zvinosanganisira donje rakanatswa, uye zvigadzirwa zvemakemikari, zvinosanganisira propylene oxide. Iyo mbishi yedonje yakacheneswa ikotoni pfupi cashmere, uye iyo donje pfupi cashmere inogadzirwa zvakanyanya muShandong, Xinjiang, Hebei neJiangsu. Kunobva pamba yekotoni yakawanda kwazvo uye inowanikwa zvakakwana.
Cotton inotora chikamu chikuru muhupfumi hwezvekurima zvekurima, uye mutengo wayo unokanganiswa nemamiriro echisikigo uye kuwanikwa kwenyika uye kudiwa. Saizvozvo, propylene oxide, chloromethane uye zvimwe zvigadzirwa zvemakemikari zvinokanganiswawo nemitengo yemafuta epasi rose. Sezvo mbishi inoverengera chikamu chikuru mumutengo wechimiro che cellulose ether, kuchinjika kwemutengo wezvakagadzirwa kunokanganisa zvakananga mutengo wekutengesa we cellulose ether.
Kuti utsungirire kumanikidzwa kwemutengo, vagadziri ve cellulose ether vanowanzoendesa kudzvanywa kune yakadzika indasitiri, asi iyo yekuchinjisa mhedzisiro inokanganiswa nekuoma kwezvigadzirwa zvehunyanzvi, kusiyana kwechigadzirwa uye mwero wemutengo wechigadzirwa uye kukosha kwakawedzerwa. Kazhinji, mabhizinesi ane yakakwirira tekinoroji zvipingamupinyi, akapfuma zvigadzirwa zvikamu uye yakakwirira yakawedzera kukosha ane mabhenefiti makuru uye anochengetedza yakagadzikana gross purofiti level. Zvikasadaro, mabhizinesi anofanirwa kutarisana nekumanikidzwa kukuru kwemitengo. Uye zvakare, kana nharaunda yekunze isina kugadzikana uye huwandu hwekuchinja kwechigadzirwa hwakakura, mabhizinesi ekumusoro emvura anonyanya kuda kusarudza vatengi vepasi vane hukuru hwekugadzira uye simba rakasimba rakazara, kuitira kuti ive nechokwadi chekubatsira kwehupfumi panguva uye kuderedza njodzi. Naizvozvo, izvi zvinodzikamisa kukudziridzwa kwemadiki-scale cellulose ether mabhizinesi kune imwe nhanho.
Cellulose ether rudzi rwechisikigo chepolymer chakatorwa, icho chine emulsification uye kumiswa hunhu. Mumhando dzakawanda, hydroxypropyl methyl cellulose ether iri HPMC ndiyo goho repamusoro, iro rinonyanya kushandiswa, kugadzirwa kwayo kuri kuwedzera nekukurumidza.
Nekuenderera mberi nekuenderera mberi kwesainzi uye tekinoroji, musika wepasi unodikanwa uri kukura, uye yepasi pemvura chiyero chekushandisa inotarisirwa kuwedzera kuenderera, uye kudiwa kwepasi kuri kuchengetedza kukura kwakagadzikana. Mumusika wepasi pemusika chimiro che cellulose ether, zvekuvaka, kubviswa kwemafuta, chikafu uye mamwe minda zvinotora chinzvimbo chikuru. Pakati pavo, chikamu chezvivakwa zvekuvaka ndicho musika mukuru wevatengi, unoverengera anopfuura makumi matatu%.
Indasitiri yekuvaka ndiyo yakakura kwazvo yekushandisa yeHPMC zvigadzirwa
Muindasitiri yekuvaka, zvigadzirwa zveHPMC zvinotamba chisungo chakakosha, kuchengetedza mvura uye zvimwe zvinokonzeresa. Mushure mekusanganisa zvishoma zveHPMC nesamende dhaka, iyo viscosity, tensile uye shear simba resimende dhaka, dhaka uye binder inogona kuwedzerwa, kuitira kuvandudza mashandiro ezvivakwa zvekuvaka, kuvandudza kunaka kwekuvaka uye mechanic kuvaka kushanda zvakanaka. Pamusoro pezvo, HPMC zvakare yakakosha kudzoreredza kugadzirwa uye kutakura kwekongiri yekutengesa, iyo inoita basa mukuvhara mvura uye kuwedzera rheological zvimiro zvekongiri. Parizvino, HPMC ndiyo inonyanya kukosha cellulose ether zvigadzirwa zvinoshandiswa mukuvaka chisimbiso zvinhu.
Indasitiri yekuvaka ndiyo yakakosha mbiru indasitiri yehupfumi hwenyika yedu. Dhata inoratidza kuti nzvimbo yekuvaka dzimba yakawedzera kubva pa7.08 bhiriyoni square metres muna 2010 kusvika 14.42 bhiriyoni masikweya metres muna 2019, ichifambisa zvakanyanya kukura kwemusika we cellulose ether.
Iyo yakazara boom yeindasitiri yezvivakwa yakatora, uye nzvimbo yekuvaka nekutengesa yakasimuka gore negore. Ruzhinji ruzivo runoratidza kuti muna 2020, kuderera kwepamwedzi-pa-gore munzvimbo itsva yekuvaka yedzimba dzekugara dzekutengesa kuri kuramba kuchidzika, pasi ne1.87% gore pagore, 2021 inotarisirwa kuenderera mberi nekugadzirisa maitiro. Mumwedzi miviri yekutanga yegore rino, chiyero chekukura kwenzvimbo yekugara yekutengeserana yakawedzera kusvika ku104,9%, kuwedzera kunoremekedzwa.
Kuchera mafuta
Musika wekuchera mainjiniya masevhisi eindasitiri musika unonyanya kukanganiswa nekudyara kweE&P kwepasirese, inosvika makumi mana muzana enzvimbo yekuongorora yepasirese iri kupihwa mukuchera mainjiniya masevhisi.
Munguva yekuchera oiri nekugadzira, zvinwiwa zvekuchera zvinoita basa rakakosha pakutakura nekumisa machipisi, kusimbisa madziro egomba uye kuenzanisa kuumbwa kwekumanikidza, kutonhora nekuzora bhiti, uye kufambisa masimba ehydrodynamic. Nokudaro, mubasa rekuchera mafuta, zvakakosha zvikuru kuchengetedza humidity yakakodzera, viscosity, fluidity uye zvimwe zviratidzo zvekuchera mvura. Polyanionic cellulose, kana PAC, inogona kukobvu, kuisa mafuta mabhiti, uye kutamisa masimba ehydrodynamic. Nekuda kweiyo yakaoma geological mamiriro enzvimbo yekuchengetera mafuta uye kuoma kwekuchera, kune huwandu hukuru hwePAC kushandiswa kudiwa.
Pharmaceutical excipients industry
Non-ionic cellulose ethers anoshandiswa zvakanyanya muindasitiri yemishonga semishonga yemishonga, yakadai semakobvu, disperants, emulsifiers uye mafirimu ekare. Inoshandiswa kupfekedza firimu uye kunamira kwemapiritsi emishonga, uye inogona kushandiswawo mukumiswa, kugadzirira maziso, mahwendefa anoyangarara uye zvichingodaro. Nekuda kwezvakaomesesa zvinodiwa pakuchena uye viscosity yemishonga cellulose ether zvigadzirwa, maitiro ekugadzira akaomarara uye nzira dzekugeza dzakanyanya kuoma. Kuenzaniswa nezvimwe zvigadzirwa zve cellulose ether, mwero wekuunganidza wakaderera, mutengo wekugadzira wakakwira, asi chigadzirwa chakawedzerwa kukosha zvakare kwakakwira. Mishonga excipients inonyanya kushandiswa mumakemikari kugadzirira mishonga, Chinese patent mushonga, biological uye biochemical zvigadzirwa uye zvimwe zvigadzirwa zvemishonga.
Nekuti iyo indasitiri yemishonga yekubatsira zvinhu yakatanga kunonoka, huwandu hwekuvandudza hwakaderera pari zvino, iyo indasitiri nzira inoda kuvandudzwa. Pakati pezvinobuda kukosha kwemishonga yemishonga yemukati, kukosha kwekubuda kwemishonga yemumba kunopa chikamu chakaderera che2% -3%, iyo yakaderera zvakanyanya pane yevatorwa mishonga yekunze (inenge 15%). Zvinogona kuoneka kuti kuchine nzvimbo huru yekuvandudzwa kwemishonga yemudzimba, iyo inotarisirwa kufambisa zvinobudirira kukura kweiyo yakakodzera cellulose ether musika.
