Vuba aha, umushakashatsi windirimbo zingirakamaro, ikigo cya tianjin cyibinyabuzima cy’inganda, ishuri ry’ubumenyi mu Bushinwa, yashyizeho ikoranabuhanga rya bio-textile enzyme, risimbuza soda ya caustic mu rwego rwo kwitegura ibikoresho byo gucapa no gusiga irangi, bizagabanya cyane imyuka y’amazi, ikiza amazi n’amashanyarazi. , kandi yasuzumwe n'inganda nk'ikindi kintu gishya cy'ikoranabuhanga mu bucuruzi bwo gucapa no gusiga amarangi mu Bushinwa.
Waba warigeze utekereza kubijyanye na T-shirt, jeans, cyangwa imyenda wambara?Nkukuri, imyenda yamabara izana kwangiza ibidukikije.Inganda zo gucapa no gusiga amarangi zahoraga zihagarariye ubushobozi bw’umusaruro w’inyuma hamwe n’umwanda mwinshi hamwe n’ingufu nyinshi.Mu myaka yashize, inganda nyinshi zo gucapa no gusiga amarangi, cyane cyane iziri mu mijyi yo mu cyiciro cya mbere, zagiye zimurwa buhoro buhoro cyangwa zirafungwa.
Muri icyo gihe, gucapa no gusiga irangi ni ingenzi mu nganda z’imyenda.Kubera igitutu cya politiki, inganda zo gucapa no gusiga amarangi zihora zishakisha udushya mu ikoranabuhanga kandi zigana ku cyerekezo cyo gucapa no gusiga irangi.
Ibinyabuzima byateguwe nindirimbo zingirakamaro, umushakashatsi wo mu kigo cya tianjin cy’ibinyabuzima by’inganda, ishuri ry’ubumenyi ry’Ubushinwa, risimbuza soda ya caustic mu rwego rwo kwitegura ibikoresho byo gucapa no gusiga irangi, birashobora kugabanya cyane gusohora amazi y’amazi, kuzigama amazi n’amashanyarazi, kandi afite yasuzumwe n'inganda nk'ikindi kintu gishya cy'ikoranabuhanga mu bucuruzi bwo gucapa no gusiga amarangi mu Bushinwa.
Inganda zo gucapa no gusiga amarangi zikeneye byihutirwa kurwanya umwanda. ”Ikibazo cy’umwanda kiriho mu nganda z’imyenda mu Bushinwa kigeze aho byihutirwa kugikemura.Umusaruro gakondo wimyenda ntabwo uzana umwanda kubidukikije gusa, ahubwo unatanga imiti yubwoko bwose bwangiza, bikangiza ubuzima bwacu.Umuryango wose ugomba gufatanya kurwanya inzira y’umwanda kandi ikangiza "" "Ku isi hari nibura imiti 8000 ikoresha imiti yica udukoko 25% mu guhinga ipamba itari kama mu gihe cyo guhindura ibikoresho fatizo mu myenda". yarekuwe n'Imihigo y'Isi.Ibi bizatera kwangirika bidasubirwaho abantu nibidukikije, kandi bibiri bya gatatu byangiza imyuka ya karubone bizakomeza nyuma yimyenda iguzwe.Bisaba litiro nyinshi z'amazi kugirango utunganyirize imyenda, cyane cyane gusiga irangi, bisaba litiro 2,4 z'amazi.
Ibarurishamibare ry’ibidukikije mu Bushinwa ryerekana ko inganda z’imyenda ari umwanda mwinshi mu nganda zikomeye.Isohora ry’imyanda y’inganda y’inganda iri mu myanya ya mbere mu nganda 41 zo mu Bushinwa, kandi isohoka ry’ibikorwa byo gucapa no gusiga irangi rirenga 70% by’amazi y’imyanda.
Byongeye kandi, nk’isoko ikomeye y’umwanda w’amazi, inganda z’imyenda mu Bushinwa nazo zikoresha umutungo munini w’amazi, zikaba zisigaye inyuma cyane ku isi mu bijyanye no gukoresha neza amazi.Raporo yerekeye gukumira no kurwanya ihumana ry’inganda mu nganda z’ingenzi zashyizwe ahagaragara n’ikinyamakuru cy’ubumenyi bw’ibidukikije mu Bushinwa, impuzandengo y’imyanda ihumanya mu Bushinwa mu gucapa no gusiga irangi amazi y’amazi yikubye inshuro 2-3 ugereranije n’ibihugu by’amahanga, kandi ikoreshwa ry’amazi ni ryinshi inshuro 3-4.Muri icyo gihe, gucapa no gusiga amarangi y’amazi ntabwo yanduye gusa mu nganda, ahubwo ni umwanda ukorwa no gucapa no gusiga amarangi y’amazi afite ibibazo bimwe na bimwe mu kuyivura.
Muri byo, umwanda uterwa no gukoresha soda nyinshi ya caustic mu kwitegura ibikoresho byo gucapa no gusiga irangi birakomeye.Ati: “Ugomba kuyivura ukoresheje soda ya caustic, kuyikomera cyane, hanyuma ukayitandukanya na aside hydrochloric, ikaba ari amazi menshi.”Ati umuyobozi wari umaze imyaka myinshi akora umwuga wo gucapa no gusiga amarangi.
Kugira ngo iki kibazo gikemuke, itsinda riyobowe nindirimbo zingirakamaro, umushakashatsi mu kigo cya tianjin cy’inganda zikoresha ikoranabuhanga mu nganda zishingiye ku ishuri ry’ubumenyi ry’Ubushinwa, ryabanje kwibanda ku iterambere ry’imisemburo mishya ishobora gusimbuza soda ya caustic.
Gutegura imisemburo ya biologiya ikemura ikibazo cyo gucapa no gusiga Irangi gakondo yo kubanza gucapa no gusiga irangi igizwe nintambwe eshanu: gutwika, gutesha agaciro, gutunganya, guhumura no kudoda.Nubwo ibigo bimwe byamahanga byahoze bitanga imisemburo ya enzyme mbere yo gucapa no gusiga irangi, ariko byakoreshwaga gusa mugushaka.
Indirimbo Hui yavuze, gutegura enzyme ni ubwoko bunoze bwo gukora neza, gukoresha bike, catisale y’ibinyabuzima idafite uburozi, kuvura ibinyabuzima bishingiye ku buryo bwo gutegura enzyme ni ugukemura inganda zo gucapa no gusiga amarangi inzira nziza yo kwanduza cyane no kuyikoresha cyane, ariko, nyuma ubwoko butandukanye bwo gutegura enzyme, igiciro kimwe cyinshi cyo gutegura enzyme yo gutegura uruganda no kutagira aho bihurira nubushakashatsi bwabafasha mu myenda, inzira yuzuye yo kwisiga irangi irangi.
Iki gihe, itsinda ryindirimbo zingenzi hamwe nibigo byinshi byageze kubufatanye bwa hafi.Nyuma yimyaka itatu, bateje imbere ubwoko butandukanye bwimyenda yo mu bwoko bwa bioenzyme yimyenda nuburyo bwo kuyibyaza umusaruro, harimo amylase, pectinase ya alkaline, xylanase na catalase.
“Gutegura - gutunganya imisemburo ya enzyme ikemura byakemuye ikibazo kitoroshye cyo gutesha ipamba ya polyester hamwe nigitambara cyiza cya polyester.Mubihe byashize, amylase desizing yashoboraga gukemura gusa imyenda yumukara hamwe nubunini bwa krahisi, kandi umwenda wumukara hamwe nuruvange rwa PVA washoboraga gutekwa no kuvanwaho hamwe na alkali yubushyuhe bwinshi.Iminsi izunguruka mu matsinda mukuru wa injeniyeri Ding Xueqin yavuze, ibice birimo silike retardant silk, ubwoko bwa polyester ubwoko bwimyenda yo hejuru yubushyuhe bwo hejuru bwa alkali guteka, bitabaye ibyo bikazagabanuka, kandi gukoresha enzyme ya biologique enzyme yingirakamaro nibyiza cyane, kugirango wirinde kugabanuka kwimyenda, kurekura na krahisi, PVA kandi bisukuye, kandi nyuma yo gutunganya imyenda wumva byoroshye kandi byoroshye, nabyo bikemura ikibazo cya tekiniki muruganda.
Zigama amazi n'amashanyarazi kandi ugabanye gusohora imyanda Dukurikije indirimbo zingirakamaro, iyo enzymatique desizing no gutunganya birangiye, ntabwo ikiza gusa ubushyuhe bwo hejuru bwibikorwa gakondo byo kuvura, ahubwo binagabanya ubwinshi bwamazi akoreshwa mugikorwa cyo kwitegura hasi. ubushyuhe, kuzigama cyane gukoresha ingufu zamazi.Ugereranije nibikorwa gakondo, bizigama 25 kugeza 50% byamazi na 40% byamashanyarazi.
Enzymatique yo kwitegura gusimbuza ikoranabuhanga gakondo rya soda ya caustic desizing hamwe na soda ya caustic yo gutunganya, ubundi bivuze ko ibicuruzwa biva muri fermentation biologiya caustic soda, imiti itunganya nindi miti, kubwibyo rero, bishobora kugabanya cyane gutunganya amazi yanduye pH nagaciro ka COD, imiti yimiti nka gusimbuza neza umukozi wo gutunganya arashobora gukora mugutegura amazi yanduye COD agaciro kazagabanuka kurenga 60%.
“Gutegura enzyme ya biocomposite ifite ibiranga uburyo bwo kuvura bworoheje, gukora neza no kwihariye.Gukoresha imiti ya bioenzyme ntacyo byangiza kuri fibre yipamba, kandi bifite ingaruka mbi zo kwangirika kumasaka ya krahisi na PVA kumyenda yumukara, bishobora kugera kubintu byiza. ”Indirimbo yavuze ko ubwiza bwa fibre fibre ikoreshwa nubu buhanga iri hejuru cyane yuburyo bwa gakondo.
Ku bijyanye n’ikibazo cy’ibiciro kireba imishinga yo gucapa no gusiga amarangi, indirimbo yingirakamaro yavuze ko imikorere ya enzyme ya biocomposite ikora neza, dosiye iri hasi, igiciro ni kimwe nabafasha muri rusange imyenda, ntabwo bizongera igiciro cyo gutunganya, inganda nyinshi z’imyenda zirashobora byemere.Byongeye kandi, gukoresha imisemburo y’ibinyabuzima mu kwitegura bishobora kugabanya cyane ikiguzi cyo kwitegura no kuzamura inyungu z’ubukungu bw’inganda z’imyenda mu kugabanya ingufu zikoreshwa n’amazi, gukuraho ikiguzi cyo gutunganya amazi y’amazi ya alkaline, no kugabanya umubare w’imiti itandukanye ya sida y’imiti. .
Ati: "Mu gukoresha tekinoroji yo kwisuzumisha ya tianfang, kwitegereza imisemburo ya metero 12,000 igitambaro cyiza cya pamba na metero 11,000 aramid ashyushye ya cabb irashobora kugabanya igiciro cya 30% na 70% ugereranije nuburyo gakondo bwa alkaline."“Ati ding.
