Cellulose ether ni ubwoko bwa polymer karemano ikomoka, ifite ibiranga emulisation no guhagarikwa. Mu bwoko bwinshi, HPMC nimwe ifite umusaruro mwinshi kandi ikoreshwa cyane, kandi ibisohoka biriyongera vuba.
Mu myaka yashize, bitewe n'izamuka ry'ubukungu bw'igihugu, umusaruro wa selulose ether mu gihugu cyanjye wiyongereye uko umwaka utashye. Muri icyo gihe, hamwe n’iterambere ry’ubumenyi n’ikoranabuhanga mu gihugu, ether zo mu rwego rwohejuru za selile zasabwaga mbere na mbere ibicuruzwa byinshi byatumizwaga mu mahanga ubu bigenda byinjira buhoro buhoro, kandi ibicuruzwa byoherezwa mu mahanga bya selile zo mu gihugu bikomeje kwiyongera. Imibare irerekana ko kuva muri Mutarama kugeza mu Gushyingo 2020, Ubushinwa bwohereza mu mahanga selulose ether bwageze kuri toni 64,806, umwaka ushize bwiyongereyeho 14.2%, bukaba bwaruta ubwinshi bwoherezwa mu mahanga muri 2019 yose.
Cellulose ether yibasiwe nigiciro cyo hejuru cya pamba：
Ibikoresho by'ibanze bya selulose ether birimo ibikomoka ku buhinzi n’amashyamba birimo ipamba itunganijwe n’ibicuruzwa bivangwa na oxyde ya propylene. Ibikoresho fatizo by'ipamba itunganijwe ni ipamba. igihugu cyanjye gifite umusaruro mwinshi w'ipamba, kandi ahakorerwa ibicuruzwa by'ipamba byibanda cyane cyane muri Shandong, Sinayi, Hebei, Jiangsu n'ahandi. Imyenda y'ipamba ni myinshi kandi itanga byinshi.
Ipamba ifata umwanya munini ugereranije nubukungu bwubuhinzi bwibicuruzwa, kandi igiciro cyacyo kigira ingaruka kubintu byinshi nkibihe kamere nibitangwa mpuzamahanga nibisabwa. Mu buryo nk'ubwo, ibikomoka ku miti nka propylene oxyde na methyl chloride nabyo bigira ingaruka ku biciro bya peteroli mpuzamahanga. Kubera ko ibikoresho fatizo bifite uruhare runini muburyo bwibiciro bya selile ya selile, ihindagurika ryibiciro fatizo bigira ingaruka ku buryo bwo kugurisha igiciro cya selire ya selile.
Mu rwego rwo guhangana nigitutu cyibiciro, abakora selile ya selile bakunze kwimurira ingufu mu nganda zo hasi, ariko ingaruka zo kwimura ziterwa nuburemere bwibicuruzwa bya tekiniki, ibicuruzwa bitandukanye nibicuruzwa byongerewe agaciro. Mubisanzwe, ibigo bifite inzitizi zubuhanga buhanitse, ibyiciro byibicuruzwa bikungahaye, nagaciro kongerewe agaciro bifite inyungu nyinshi, kandi ibigo bizakomeza urwego ruhamye rwinyungu rusange; bitabaye ibyo, ibigo bigomba guhura nigitutu kinini. Byongeye kandi, niba ibidukikije byo hanze bitajegajega kandi n’urwego rw’imihindagurikire y’ibicuruzwa ni runini, amasosiyete y’ibikoresho byo mu rwego rwo hejuru yiteguye guhitamo abakiriya bo hasi bafite umusaruro mwinshi n’imbaraga nini zuzuye kugira ngo inyungu z’ubukungu ku gihe kandi zigabanye ingaruka. Kubwibyo, ibi bigabanya iterambere ryinganda ntoya ya selile ether yinganda kurwego runaka.
Imiterere yisoko ryo hepfo：
Hamwe nogukomeza gutera imbere mubumenyi nikoranabuhanga, isoko ryo hasi ryisoko riziyongera. Muri icyo gihe, ingano yimikorere yo hasi iteganijwe gukomeza kwaguka, kandi ibyifuzo byo hasi bizakomeza iterambere rihamye. Muburyo bwo kumasoko yimbere ya selulose ether, ibikoresho byubaka, ubushakashatsi bwamavuta, ibiryo nindi mirima bifite umwanya wingenzi. Muri byo, urwego rwibikoresho byubaka nisoko rinini ryabaguzi, rirenga 30%.
Inganda zubaka nu murima munini wabaguzi wibicuruzwa bya HPMC：
Mu nganda zubaka, ibicuruzwa bya HPMC bigira uruhare runini mu guhuza no gufata amazi. Nyuma yo kuvanga umubare muto wa HPMC na sima ya sima, irashobora kongera ubukonje, ubukana ndetse nogukata imbaraga za sima ya sima, minisiteri, binder, nibindi, bityo bikazamura imikorere yibikoresho byubwubatsi, kuzamura ubwubatsi nubwubatsi bwububiko. Byongeye kandi, HPMC nayo idindiza cyane gukora no gutwara beto yubucuruzi, ishobora gufunga amazi no kuzamura imvugo ya beto. Kugeza ubu, HPMC nigicuruzwa nyamukuru cya selulose ether ikoreshwa mukubaka ibikoresho bifunga kashe.
Inganda zubaka ninganda zingenzi zubukungu bwigihugu cyanjye. Aya makuru yerekana ko ubuso bwubatswe bw’imyubakire y’amazu bwiyongereye buva kuri metero kare 7.08 muri 2010 bugera kuri metero kare 14.42 muri 2019, ibyo bikaba byaratumye iterambere ry’isoko rya selile ryiyongera.
Iterambere rusange muri rusange ryinganda zitimukanwa ryongeye kwiyongera, kandi aho kubaka no kugurisha byiyongereye uko umwaka utashye. Amakuru rusange yerekana ko muri 2020, igabanuka rya buri kwezi-ku-mwaka mu gice gishya cy’imyubakire y’amazu atuyemo y’ubucuruzi cyagabanutse, kandi kugabanuka kw’umwaka kwabaye 1.87%. Muri 2021, biteganijwe ko inzira yo gukira izakomeza. Kuva muri Mutarama kugeza Gashyantare uyu mwaka, ubwiyongere bw’ahantu hagurishwa amazu y’ubucuruzi n’amazu yo guturamo bwongeye kugera kuri 104.9%, bikaba byiyongera cyane.
Gucukura peteroli:
Isoko rya serivisi zikora inganda zikora ibicuruzwa byibasiwe cyane nubushakashatsi niterambere ryisi yose, hafi 40% byumushinga wubushakashatsi ku isi wahariwe serivisi zubwubatsi.
Mugihe cyo gucukura amavuta, gucukura amazi bigira uruhare runini mugutwara no guhagarika ibiti, gushimangira inkuta zumwobo no kuringaniza umuvuduko wogukora, gukonjesha no gusiga amavuta, no gukwirakwiza ingufu za hydrodinamike. Kubwibyo, mubikorwa byo gucukura peteroli, ni ngombwa cyane gukomeza ubushuhe bukwiye, ubwiza, amazi nibindi bimenyetso byerekana amazi. Cellulose ya polyanionic, PAC, irashobora kubyimba, gusiga amavuta bito, no kohereza imbaraga za hydrodynamic. Bitewe nuburyo bugoye bwa geologiya mububiko bwa peteroli hamwe ningorabahizi yo gucukura, harakenewe cyane PAC.
Inganda zikoreshwa mu bya farumasi:
Ether ya nonionic selulose ikoreshwa cyane mubikorwa bya farumasi nkibikoresho bya farumasi nkibibyimbye, ibitatanya, emulisiferi hamwe nabakora firime. Ikoreshwa mugutwikira firime no gufatisha ibinini bya farumasi, kandi irashobora no gukoreshwa muguhagarika, gutegura amaso, gutegura ibinini bireremba hejuru, nibindi. Kubera ko imiti ya selireose yo mu rwego rwa farumasi isabwa cyane kubijyanye nubuziranenge nubwiza bwibicuruzwa, inzira yo gukora irasa bigoye kandi hariho uburyo bwinshi bwo gukaraba. Ugereranije nandi manota yibicuruzwa bya selulose ether, igipimo cyo gukusanya kiri hasi kandi nigiciro cyumusaruro kiri hejuru, ariko agaciro kiyongereye kubicuruzwa nako kari hejuru. Ibikoresho bya farumasi bikoreshwa cyane mubicuruzwa byateguwe nko gutegura imiti, imiti yipatanti yubushinwa nibicuruzwa bya biohimiki.
Bitewe no gutangira gutinda kw’inganda zikoresha imiti mu gihugu cyanjye, urwego rusange rwiterambere ruri hasi, kandi n’inganda zigomba kurushaho kunozwa. Mu gaciro k’imyororokere y’imiti yo mu gihugu, agaciro k’imyambarire y’imiti yo mu rugo kangana na 2% kugeza kuri 3%, ibyo bikaba biri hasi cyane ugereranije n’ibicuruzwa biva mu mahanga biva mu mahanga, bingana na 15%. Birashobora kugaragara ko imiti yimiti yo murugo igifite ibyumba byinshi byiterambere., Biteganijwe ko bizamura neza iterambere ryisoko rya selile ifitanye isano.
Urebye umusaruro wa selile yo mu gihugu imbere, Shandong Head ifite ubushobozi bunini bwo gukora, bingana na 12.5% yubushobozi bwose bwo gukora, ikurikirwa na Shandong RUITAI, Shandong YITENG, Amajyaruguru ya TIANPU n’inganda n’ibindi bigo. Muri rusange, amarushanwa mu nganda arakaze, kandi biteganijwe ko kwibandaho biziyongera.
