Dukurikije imibare ihari, ubushobozi bw’umusaruro w’inzitizi y’amazi mu Bushinwa ugera kuri toni 2000 ku kwezi mu 2023, ibyo bikaba byiyongereye cyane ugereranije na toni 800 ku kwezi umwaka ushize.Nyamara, ubwo bushobozi bwagize uruhare runini mu nganda zikora impapuro.Ikibaho cy’amazi gishingiye ku mazi mu Bushinwa ahanini kigenewe gupakira ibiryo, kandi kigurishwa cyane cyane ku isoko ryo hanze.Niba bizakomeza iterambere ryiza mugihe kizaza ahanini biterwa no guhitamo politiki mugihugu ndetse no mumahanga.
Duhereye aho duhagaze, dore inzira zingenzi zamazi ashingiye kumazi.
Abakiriya muri iki gihe ntibagihaze ubwiza bwa barrière.Bashakisha ibisubizo byabugenewe kugirango bashoboze gupakira neza mubikorwa bitandukanye.Ikibaho kigomba kuba gifite amazi kandi kidashobora kwihanganira amavuta hamwe nuburinganire bwihariye nkumuvuduko ukabije w’imyuka yoherezwa mu kirere (MVTR) cyangwa igipimo cyohereza umwuka wa ogisijeni (OTR), gisabwa mu gusaba gukoreshwa.Kurugero, OTR, nkibiri munsi ya 0,02 cm3 / m2 / kumunsi kugeza ubu, ikundwa mugupakira imbuto zumye.Mu buryo nk'ubwo, gupakira ibikoresho by'ifu bisaba MVTR nkeya.Ikwirakwizwa rya acrylic gakondo rishobora gutanga gusa agaciro ka MVTR hagati ya 100 kugeza 200g / m 2 / kumunsi, ariko Ikwirakwizwa rya High Performance Barrier (HPB) rishobora gutanga agaciro ka MVTR kari munsi ya 50g / m 2 / kumunsi cyangwa na 10g / m 2 / kumunsi.
Guhindura buhoro buhoro HPB kuva muri plastiki byagaragaye mugukoresha ikoreshwa rya HPB kurwego rwinganda.Bitandukanye no gupakira ibiryo byita cyane kumutekano, gupakira inganda byibanda kumikorere ya barrière nigiciro cyumusaruro.Ipaki ya HPB irashobora kugabanywamo ibicuruzwa byinshi bipfunyika hamwe nibicuruzwa bya buri munsi.Inganda zipakurura inganda bivuga ubwoko bwose bwimifuka ya valve ikoreshwa mugutwara ibikoresho bya granular, nka sima nifu ya chimique.Imifuka yimpapuro zisanzwe ziboneka mubunini bwa 25 kg cyangwa 50 kg.Inzitizi ishingiye ku mazi, nkuburyo burambye bwa plastiki, irashobora kwemeza ubushyuhe hamwe nigiciro cya MVTR kugirango dushyigikire neza gupakira imikorere yimifuka yimpapuro mumashanyarazi yihuse.Ibigo byabapayiniya biteza imbere iterambere ryibicuruzwa bya HPB birimo Alou, BASF, na Covestro.HPB irashobora gutanga inzitizi yifuzwa ariko inyungu zayo nayo ifite ubucuruzi.Igiciro cy'umusaruro ni imwe mu mbogamizi zo kuzamuka kw'isoko.Ibikoresho bya buri munsi bipfunyika bivuga gupakira ibicuruzwa nka detergent, shampoo, hamwe no kwita ku ruhu, ibyinshi muri byo ni imifuka ya garama magana kugeza kuri kilo ebyiri.Ibicuruzwa bya chimique bya buri munsi birasabwa cyane muburyo bwo gukora inzitizi kuruta imifuka ya valve.Irasaba ibintu bikomeye nko kugenzura ubushuhe, guhumeka neza no kurinda urumuri.
Urebye ko plastiki idashobora kwangirika, ibikoresho bishobora kuvugururwa bifatwa neza n’abakiriya n’ibidukikije byangiza ibidukikije, ibyinshi muri byo bikaba ari inzitizi zishingiye kuri bio.Mu gihe kirenga umwaka, ababikora bake batangije ibicuruzwa byabo bishingiye kuri bio, biteza imbere ikoreshwa mubikorwa bitandukanye, cyane cyane inganda zipakira ibiryo.Kuva kuri bariyeri ikwirakwizwa kugeza gucapa wino, bio-ishingiye kubicuruzwa biri hagati ya 30% na 90%.Kwinjiza ibikoresho bya nanocellulose byarushijeho gutandukanya portfolio yinzitizi zishingiye kuri bio.Ibigo bitanga ibinyabuzima bishobora kubamo ibinyabuzima birimo Basf, Covestro, Siegwerk, Wanhua, Shengquan, Qihong, Tangju n'ibindi. Iterambere ry'ibikoresho bya nanocellulose ku isoko mpuzamahanga biracyari mu ntangiriro.Ubushakashatsi bwakorewe mubikorwa byinshi ninganda, harimo gukora impapuro, gutwika, imiti ya buri munsi na bateri yingufu.Nyamara, ubushakashatsi bwinshi bufatwa nkibisanzwe muriki cyiciro, ubushakashatsi bwimbitse kandi burakenewe.Ubushakashatsi bujyanye no gushyira mubikorwa bigomba kuba mubufatanye bwa hafi.Kwiga no gukora iperereza bigomba kurenga Cellulose Nanofibrils (CNF) cyangwa Microfibrillated selulose (MFC), kugirango utange amahitamo menshi kubakiriya bahitamo imwe ishobora gushyigikira neza ibyo bapakira.
80% by'ibicuruzwa bikomoka ku mbogamizi zirambye bituruka ku masoko yo mu Bushinwa yo hanze, nk'Uburayi, Amerika y'Amajyaruguru na Ositaraliya.Ibisabwa ku mbaho zishingiye ku mazi ku isoko rya Ositaraliya byiyongereye cyane mu myaka yashize.Politiki yo kubuza plastike muri Hong Kong nayo yagize uruhare mu kuzamura ikibaho gishingiye ku mazi.Kugeza ubu icyifuzo cy’imbere mu Bushinwa kiracyafite intege nke muri iki gihe.Iterambere ryo gukwirakwiza amazi ntirishingiye gusa ku mbaraga z’ibicuruzwa gusa ahubwo no kuri politiki y’inganda.Umwaka ushize cyangwa urenga, abayobozi b’ibanze mu Bushinwa bahindutse bava mu guteza imbere plastiki ishobora kwangirika bahinduka ubundi buryo budafite amashanyarazi butandukanye, cyane cyane ibikoresho bisubirwamo kandi bishobora kuvugururwa.
