Umujyi wa Xinxiang, nk'itsinda ry'ingenzi ry'ibikoresho byo kuyungurura mu gihugu, ufiteakayunguruzo k'umwuka gatuma umwuka uhagarara nezaInganda zikora ibikoresho by’ibanze mu buryo bw’ “ishusho nk’iy’udupira”. Inganda zitanga ibikoresho by’ibanze nka meltblown fabric na fiberglass ziherereye mu Karere ka Fengquan mu majyaruguru y’umupaka w’inganda, mu gihe inganda zikora ibikoresho by’ibanze zikorera mu gace k’Iterambere ry’Ubukungu ko mu majyepfo, zigakora uruhererekane rwuzuye rw’ibicuruzwa. Abahanga mu bya siyansi bo mu gace batangaje ko ubu buryo bwo gukwirakwiza ibintu butuma urwego rw’ubwikorezi ruguma hagati y’ibikoresho by’ibanze n’ibicuruzwa byuzuye mu ntera ya kilometero 30, bigabanura neza ikiguzi cy’ibikoresho.
Udushya mu ikoranabuhanga twabaye urufunguzo rwo kunyuramo. Ibigo by’ibikoresho bya Xinxiang muri rusange byongera igipimo cy’ishoramari mu bushakashatsi no mu iterambere kugeza kuri 5%-8%, biruta impuzandengo y’inganda. Umuyobozi wa tekiniki w’ikigo giciriritse yagaragaje imiterere yacyo nshya ya "gradient filter layer": binyuze mu gushyira hejuru y’ibice bitanu by’ibikoresho by’ibirahure bifite ubucucike butandukanye, bigabanya igabanuka ry’umuvuduko wa mbere ho 15% mu gihe bigumana uburyo bwo kuyungurura bwa mikoroni 0.01. Iri koranabuhanga ryabonye patenti y’icyitegererezo cy’ibikoresho, kandi ibicuruzwa bishyigikira byashyizwe ku rutonde rw’abatanga ibicuruzwa muri Sany Heavy Industry.
Isoko rigaragaza itandukaniro rigaragara. Ibigo binini byafunguye amasoko yo mu mahanga binyuze mu cyemezo cya ISO 8573, kandi ibicuruzwa byabyo byoherezwa mu majyepfo y'uburasirazuba bwa Aziya no mu Burasirazuba bwo Hagati. Igipimo cy'ubucuruzi bwo mu mahanga cy'ikigo gikomeye cyageze kuri 35%. Ku rundi ruhande, inganda nto n'iziciriritse zibanda ku masoko yihariye, nko kwibanda ku bintu birwanya static filter elements mu gukata laser cyangwa guteza imbere ikoranabuhanga ryo gusiga hydrophobic rikwiriye ahantu harangwa n'ubushuhe bwinshi. Iri rushanwa ryihariye ryongereye isoko rya Xinxiang filter elements ku isoko ryo hagati mu gihugu kugeza kuri 28% (nk'uko bigaragazwa n'amakuru y'inganda za 2023).
Ariko, kuvugurura inganda bihura n'ibibazo bifatika. Mu gace kamwe k'inganda mu Karere ka Hongqi, ibintu by'ibigo bitatu bito n'ibiciriritse bisangiye laboratwari y'ibizamini birakwirakwiriye cyane. Nyir'ubucuruzi yemeye mu buryo bweruye ati: “Igiciro cy'igikoresho kimwe cyo gupima cyatumijwe mu mahanga kirenze miliyoni imwe y'amayuan, bikaba ari umutwaro uremereye ku nganda nto.” Muri urwo rwego, ubuyobozi bw'ibanze bwayoboye ishyirwaho ry'ihuriro ry'inganda zikora ibikoresho byo kuyungurura, rifasha ibigo bito n'ibiciriritse kugabanya ikiguzi cyabyo cyo gusesengura no guteza imbere ubushakashatsi binyuze mu gusangira ibikoresho, kugura hamwe n'ibindi bikoresho.
Igitutu cy’impinduka cyatewe na politiki yo kurengera ibidukikije nacyo kiragaragara. Amabwiriza mashya y’igihugu agira ati “Imipaka y’Ingufu Ntoya ku Kompresa z’Imyuka” yashyizweho mu 2023 yashyize imbere ibisabwa byinshi ku gipimo cy’ingaruka ku bushobozi bw’ingufu mu byuma biyungurura. Ibigo bya Xinxiang byasubije vuba. Ibicuruzwa byabo by’ingenzi byageze ku rwego rwo gukoresha ingufu neza, kandi bimwe mu bigo byatangiye gushyiraho ubushakashatsi n’iterambere ry’ibikoresho biyungurura ibyuma bishobora gukaraba no kongera gukoreshwa.
Mu rwego rw'inganda, inzira y'iterambere ry'inganda za Xinxiang zikoresha icyuma gishyushya umwuka igaragaza inzira isanzwe y'impinduka mu nganda z'Ubushinwa - mu gihe inyungu z'ibiciro zigenda zigabanuka buhoro buhoro, binyuze mu guhanga udushya duto mu ikoranabuhanga no mu bufatanye mu nganda, hashyizweho uburyo bushya bwo guhangana mu nzego zihariye. Ubu bwoko bw' "ivugurura buhoro buhoro" bushobora kuba budatangaje nk'udushya duhungabanya, ariko butanga icyitegererezo nyacyo cy'iterambere rirambye ry'inganda zo mu karere.
