Cellulose ether rudzi rwezvinhu zvinobva mupolymer yechisikigo, zvine hunhu hwe emulsification uye suspension. Pakati pemhando dzakawanda, HPMC ndiyo ine simba guru uye inonyanya kushandiswa, uye simba rayo riri kuwedzera nekukurumidza.
Mumakore achangopfuura, nekuda kwekukura kwehupfumi hwenyika, kugadzirwa kwe cellulose ether munyika yangu kwakawedzera gore negore. Panguva imwe chete, nekuvandudzwa kwesainzi netekinoroji yemuno, cellulose ethers dzemhando yepamusoro dzaida huwandu hwakawanda hwezvinhu zvinotengeswa kunze kwenyika ikozvino dzava kuwanikwa zvishoma nezvishoma, uye huwandu hwezvinhu zvinotengeswa kunze kwenyika hwe cellulose ethers dzemuno huri kuramba huchiwedzera. Data rinoratidza kuti kubva muna Ndira kusvika Mbudzi 2020, cellulose ether yekuChina yakasvika matani 64,806, kuwedzera kwegore negore kwe14.2%, kwakakwira kupfuura huwandu hwezvinhu zvinotengeswa kunze kwenyika mugore rese ra2019.
Cellulose ether inokanganiswa nemitengo yedonje iri kukwira：
Zvinhu zvikuru zvekushandisa mu cellulose ether zvinosanganisira zvigadzirwa zvekurima nemasango zvinosanganisira donje rakacheneswa uye zvigadzirwa zvemakemikari zvinosanganisira propylene oxide. Zvinhu zvekushandisa mu donje rakacheneswa idonje rakacheneswa. Nyika yangu ine kugadzirwa kwedonje kwakawanda, uye nzvimbo dzekugadzira donje dzakanyanya kuungana muShandong, Xinjiang, Hebei, Jiangsu nedzimwe nzvimbo. Zvigadzirwa zvedonje zvakawanda uye zviripo zvakawanda.
Donje rine chikamu chikuru muchimiro chehupfumi hwezvekurima, uye mutengo waro unokanganiswa nezvinhu zvakawanda zvakaita semamiriro echisikigo uye kuwanikwa nekudiwa kwenyika dzese. Saizvozvowo, zvigadzirwa zvemakemikari zvakaita sepropylene oxide nemethyl chloride zvinokanganiswawo nemitengo yemafuta asina kucheneswa pasi rose. Sezvo zvinhu zvisina kucheneswa zvichiverengera chikamu chikuru muchimiro chemutengo we cellulose ether, kuchinja kwemitengo yezvinhu zvisina kucheneswa kunokanganisa zvakananga mutengo wekutengesa we cellulose ether.
Mukupindura kumanikidzwa kwemutengo, vagadziri ve cellulose ether vanowanzo endesa kumanikidzwa kumaindasitiri ari pasi pemvura, asi mhedzisiro yekufambisa inokanganiswa nekuoma kwezvigadzirwa zvehunyanzvi, kusiyana kwezvigadzirwa uye kukosha kwemutengo wezvigadzirwa. Kazhinji, mabhizinesi ane zvipingamupinyi zvepamusoro zvehunyanzvi, mapoka ezvigadzirwa akapfuma, uye kukosha kwakawedzerwa kune zvakanakira zvikuru, uye mabhizinesi achachengetedza mwero wakadzikama wepurofiti yakazara; zvikasadaro, mabhizinesi anofanira kutarisana nekumanikidzwa kwemutengo kwakanyanya. Pamusoro pezvo, kana nharaunda yekunze isina kugadzikana uye huwandu hwekuchinja kwezvigadzirwa hwakakura, makambani epamusoro-soro anoda kusarudza vatengi vari pasi pemvura vane huwandu hukuru hwekugadzira uye simba rakasimba rekuona kuti mabhenefiti ehupfumi anowanikwa panguva yakakodzera uye kuderedza njodzi. Naizvozvo, izvi zvinoganhurira kukura kwemakambani madiki e cellulose ether kusvika pamwero wakati.
Maumbirwo eMusika wePasi：
Nekufambira mberi kwesainzi netekinoroji, musika wezvinodiwa uchakura zvinoenderana. Panguva imwe chete, huwandu hwekushandiswa kwezvinodiwa zvicharamba huchikura, uye zvinodiwa zvicharamba zvichikura. Mumamiriro emusika we cellulose ether, zvinhu zvekuvaka, kutsvaga mafuta, chikafu nezvimwe zvinhu zvine chinzvimbo chikuru. Pakati pavo, chikamu chezvinhu zvekuvaka ndicho musika wevatengi vakawanda, chinodarika 30%.
Indasitiri yekuvaka ndiyo munda mukuru wevatengi vezvigadzirwa zveHPMC：
Muindasitiri yekuvaka, zvigadzirwa zveHPMC zvine basa rakakosha mukubatanidza uye kuchengetedza mvura. Mushure mekusanganisa huwandu hushoma hweHPMC nesimbi yesimbi, zvinogona kuwedzera viscosity, kusimba kwekukwesha uye kupwanya simende, simbi, binder, nezvimwewo, nokudaro zvichivandudza mashandiro ezvigadzirwa zvekuvaka, kuvandudza kunaka kwekuvaka uye kushanda zvakanaka kwekuvaka. Pamusoro pezvo, HPMC zvakare isimbi yakakosha pakugadzira nekufambisa kongiri yekutengeserana, iyo inogona kukiya mvura uye kuwedzera rheology yekongiri. Parizvino, HPMC ndiyo chigadzirwa chikuru che cellulose ether chinoshandiswa mukuvaka sealing zvinhu.
Indasitiri yekuvaka iindasitiri huru yehupfumi hwenyika yangu. Ruzivo rwunoratidza kuti nzvimbo yekuvaka dzimba yakawedzera kubva pamamita 7.08 bhiriyoni muna 2010 kusvika pamamita 14.42 bhiriyoni muna 2019, izvo zvakakurudzira zvikuru kukura kwemusika we cellulose ether.
Kubudirira kweindasitiri yezvivakwa kwakawedzera, uye nzvimbo yekuvaka nekutengesa yakawedzera gore negore. Ruzivo rweveruzhinji runoratidza kuti muna 2020, kudzikira kwemwedzi wega wega kwenzvimbo itsva yekuvaka dzimba dzekutengeserana kwave kudzikira, uye kudzikira kwegore negore kwave kuri 1.87%. Muna 2021, maitiro ekupora anotarisirwa kuramba achienderera mberi. Kubva muna Ndira kusvika Kukadzi gore rino, mwero wekukura kwenzvimbo yekutengesa dzimba dzekutengeserana nedzimba dzekugara wakawedzera kusvika 104.9%, inova kuwedzera kukuru.
Kuchera Oiri:
Musika weindasitiri yemabasa einjiniya yekuchera unokanganiswa zvakanyanya nekudyara mari pasi rose mukutsvaga nekusimudzira, neinenge 40% yenzvimbo dzekuongorora pasi rose dzakatsaurirwa kumabasa einjiniya yekuchera.
Panguva yekuchera mafuta, mvura yekuchera inoita basa rakakosha mukutakura nekumisa zvidimbu, kusimbisa madziro emaburi uye kuenzana kwekumanikidzwa kwekugadzira, kutonhora nekuzora mabhora ekuchera, uye kutumira simba remvura inonaya. Saka, mubasa rekuchera mafuta, zvakakosha kuchengetedza hunyoro hwakakodzera, viscosity, fluidity nezvimwe zviratidzo zvemvura yekuchera. Polyanionic cellulose, PAC, inogona kukora, kunyorovesa bhora rekuchera, uye kutumira simba remvura inonaya. Nekuda kwemamiriro ezvinhu akaomarara munzvimbo yekuchengetera mafuta uye kuoma kwekuchera, pane kudiwa kukuru kwePAC.
Mishonga accessories indasitiri:
MaNonionic cellulose ethers anoshandiswa zvakanyanya muindasitiri yemishonga sezvinhu zvinobatsira mumishonga zvakaita sezvikukutu, zvinoparadzira, zvinosanganisa makemikari uye zvinogadzira firimu. Inoshandiswa pakuputira firimu uye kunamira mapiritsi emishonga, uye inogona kushandiswawo pakumisikidza, kugadzira maziso, mapiritsi anoyangarara, nezvimwewo. Sezvo pharmaceutical grade cellulose ether ine zvinodiwa zvakanyanya pakuchena uye kusimba kwechigadzirwa, maitiro ekugadzira akaomarara uye kune nzira dzakawanda dzekusuka. Zvichienzaniswa nedzimwe mhando dzezvigadzirwa zve cellulose ether, mwero wekuunganidza wakaderera uye mutengo wekugadzira wakakwira, asi kukosha kwekuwedzera kwechigadzirwa kwakakwirawo. Mishonga inobatsira mumishonga inonyanya kushandiswa muzvigadzirwa zvekugadzirira zvakaita sekugadzira makemikari, mishonga yeChina patent uye zvigadzirwa zvebiochemical.
Nekuda kwekutanga kweindasitiri yezvinobatsira mishonga munyika yangu, huwandu hwekuvandudzwa kwazvino hwaderera, uye mashandiro eindasitiri iyi anofanira kuvandudzwa zvakanyanya. Mukukosha kwekugadzirwa kwemishonga yemuno, kukosha kwezvinobatsira mishonga yemuno kunosvika chikamu chidiki che2% kusvika 3%, icho chiri pasi zvakanyanya pane chikamu chezvinobatsira mishonga yekunze, icho chiri 15%. Zvinogona kuonekwa kuti zvinobatsira mishonga yemuno zvichiri nenzvimbo yakawanda yekuvandudzwa. Zvinotarisirwa kukurudzira kukura kwemusika we cellulose ether wakabatana.
Kubva pamaonero ekugadzirwa kwe cellulose ether yemuno, Shandong Head ndiyo ine simba guru rekugadzira, ichitora 12.5% yesimba rese rekugadzira, ichiteverwa neShandong RUITAI, Shandong YITENG, North TIANPU Chemical nedzimwe makambani. Kazhinji, makwikwi muindasitiri iyi akanyanya, uye huwandu hwevanhu vanotarisirwa kuwedzera.
