Munguva pfupi yapfuura, yakakosha rwiyo muongorori, tianjin Institute of industrial biology, Chinese academy of sciences, yakagadzira bio-textile enzyme tekinoroji, iyo inotsiva caustic soda mukugadziriswa kwekudhinda uye dhayi zvinhu, ichaderedza zvakanyanya kusvibiswa kwemvura inobuda, kuchengetedza mvura nemagetsi. , uye yakaongororwa neindasitiri seimwe yakakosha hunyanzvi hwetekinoroji muindasitiri yekudhinda nekudhaya yeChina.
Wati wambofunga nezvemamiriro akaita T-shirt, jini, kana rokwe raunopfeka here?Sezvineiwo, zvipfeko zvine mavara zvinounza kukanganisa kukuru kune zvakatipoteredza.Indasitiri yekudhinda uye yekudhaya yakagara iri mumiriri wekudzokera kumashure kwekugadzira nekusvibiswa kwakanyanya uye kushandiswa kwesimba kwakanyanya.Mumakore achangopfuura, maindasitiri mazhinji emuno anodhinda nekudhaya, kunyanya ari mumaguta ekutanga, akabviswa zvishoma nezvishoma kana kutovharwa.
Panguva imwecheteyo, kudhinda uye kudhaya chinhu chakakosha muindasitiri yemachira.Pasi pekumanikidzwa kwemitemo, indasitiri yekudhinda nekudhaya inogara ichitsvaga hunyanzvi hwetekinoroji uye ichienda kwakanangana nekudhinda kwegirinhi nekudhaya.
Iyo biotechnology, yakagadziridzwa nerwiyo rwakakosha, muongorori kubva kuTianjin Institute of Industrial biology, Chinese academy of sciences, iyo inotsiva caustic soda mukutanga kudhindwa uye dhayi zvinhu, inogona kuderedza zvakanyanya kubuda kwetsvina, kuchengetedza mvura nemagetsi, uye ine yakaongororwa neindasitiri seimwe yakakosha tekinoroji innovation muChina indasitiri yekudhinda nekudhaya.
Indasitiri yekudhinda nekudhaya inoda nekukurumidza kurwisa kusvibiswa”Dambudziko riripo iye zvino rekusvibisa muindasitiri yemachira yekuChina rasvika padanho rekuti rigadziriswe nechimbichimbi.Kugadzirwa kwemavara echinyakare hakungounzi kusvibiswa kwezvakatipoteredza, asi kunoburitsa marudzi ese emakemikari anokuvadza, zvichikonzera kukanganisa kuhutano hwedu.Sosaiti yese inofanirwa kuramba pamwe chete kusvibisa uye kugadzirwa kwekudya ""Kune makemikari anosvika zviuru zvisere pasirese anoshandisa zvikamu makumi maviri neshanu muzana zvemishonga yekuuraya zvipembenene kurima donje risiri reorganic mukuchinja chinja zvinhu kuita machira," sekureva kwedata. yakaburitswa nePasi Pledge.Izvi zvinotungamira mukukuvadzwa kusingagadziriswe kuvanhu uye nharaunda, uye zvikamu zviviri kubva muzvitatu zvekubuda kwekabhoni zvichaenderera mberi mushure mekunge zvipfeko zvatengwa.Zvinotora makumi emarita emvura kugadzira jira, kunyanya kudhayiwa kwejira, izvo zvinoda marita 2.4 emvura.
Huwandu hwezvakatipoteredza hweChina hunoratidza kuti indasitiri yemachira ndiyo inonyanya kusvibisa mumaindasitiri akakosha.Kuburitswa kwemvura yetsvina yeindasitiri yemachira kuri pakati pepamusoro pakati pemaindasitiri makumi mana nerimwe muChina, uye kuburitswa kwekudhinda nekudhaya kunodarika makumi manomwe muzana emvura inoraswa yemachira.
Pamusoro pezvo, senzvimbo yakakosha yekusvibiswa kwemvura, indasitiri yemachira yekuChina inoshandisawo huwandu hukuru hwezviwanikwa zvemvura, kuseri kwepasirese maererano nemashandisirwo emvura.Zvinoenderana neshumo pamusoro pekudzivirira uye kudzora kusvibiswa kwemaindasitiri mumaindasitiri akakosha akaburitswa neChina yezvesainzi yezvemamiriro ekunze, avhareji yetsvina muChina inodhinda uye kudhaya mvura yetsvina yakakwira zvakapetwa ka2-3 pane yedzimwe nyika, uye kushandiswa kwemvura kwakakwira zvakanyanya. se 3-4 nguva.Panguva imwecheteyo, kudhinda uye kudhayira mvura yakasvibiswa haisi iyo chete inonyanya kusvibisa muindasitiri, asiwo sludge inogadzirwa nekudhinda uye kudhaya tsvina yemvura ine mamwe matambudziko mukurapa.
Pakati pavo, kusvibiswa kunokonzerwa nekushandiswa kwehombe yakawanda ye caustic soda mukugadzirisa kudhindwa uye kudhaya zvinhu kunonyanya kuipa."Unofanirwa kuibata necaustic soda, woipisa nesimba, wobva waibvisa nehydrochloric acid, inova mvura yakawanda inorasa."Akadaro maneja akanga ashanda muindasitiri yokudhinda nokudhaya kwemakore akawanda.
Kugadzirisa mamiriro ezvinhu aya, chikwata chinotungamirwa nerwiyo rwakakosha, muongorori wepaTianjin Institute of Industrial Biotechnology pasi peChinese academy of sciences, chakatanga kunanga kugadzirwa kwegadziriro itsva dzeenzayemu inogona kutsiva caustic soda.
Biological enzyme kugadzirira inogadzirisa dambudziko rekudhinda uye kudhayaIchinyakare pre-kudhinda uye kudhaya maitiro ane matanho mashanu: kupisa, kudhiza, kunatsa, kuchena uye silking.Kunyangwe mamwe makambani ekunze aimbogadzira gadziriro ye enzyme asati adhinda uye kudhaya, asi aingoshandiswa mukuita dhizaini.
Song Hui akati, gadziriro ye enzyme imhando yekushanda kwepamusoro, kushandiswa kwakaderera, kusina-chepfu biological catalyst, biological treatment yakavakirwa pane enzyme yekugadzirira nzira ndeyekugadzirisa kudhinda uye kudhaya indasitiri nzira yakanaka yekusvibiswa kwepamusoro uye kushandiswa kwakanyanya, asi, mushure mekuita. iwo marudzi ekugadzirira enzyme, imwe chete yakakwira mutengo wekugadzira enzyme yekomboni uye kushomeka kwekuenderana neanobatsira machira ekutsvagisa, yakazara dhayi enzymatic pretreatment process haisati yaumbwa.
Panguva ino, rwiyo rwakakosha timu uye akati wandei makambani asvika pakubatana.Mushure memakore matatu, vakagadzira akasiyana emhando yepamusoro machira bioenzyme kugadzirira uye maitiro avo ekugadzira, anosanganisira amylase, alkaline pectinase, xylanase uye catalase.
"Desizing - kunatsa komboni enzyme kugadzirira kwagadzirisa dambudziko rakaoma rekugadzira polyester donje uye yakachena polyester grey jira.Kare, amylase desizing yaingokwanisa kugadzirisa jira grey ne starch sizing, uye jira grey nePVA musanganiswa waigona kungobikwa nekubviswa nekupisa kwakanyanya alkali.Days spinning group chief engineer Ding Xueqin akati, macompounds ane flame retardant sirika, polyester jira remhando dzakasiyana tembiricha alkali yekubika desizing, zvikasadaro inodzikira, uye kushandiswa kwebiological compound enzyme desizing effect yakanaka kwazvo, kudzivirira jira racho kuderera, kuregererwa. uye starch, PVA uye yakachena, uye mushure mekugadzira jira rinonzwa rakapfava uye rakapfava, rinogadzirisawo dambudziko rehunyanzvi kufekitori.
Chengetedza mvura nemagetsi uye kuderedza kubuda kwetsvinaMaererano nerwiyo rwakakosha, kana iyo enzymatic deizing uye yekunatsa yapera, haingochengetedze tembiricha yepamusoro yemaitiro echinyakare kurapwa, asi zvakare inoderedza huwandu hwehupfu hunoshandiswa mu pretreatment process pakadzika. tembiricha, zvakanyanya kuchengetedza iyo steam simba rekushandisa.Zvichienzaniswa nemaitiro echinyakare, inochengetedza 25 kusvika 50 muzana yemhepo uye 40 muzana yemagetsi.
Enzymatic pretreatment process inotsiva yechinyakare tekinoroji ye caustic soda desizing uye caustic soda yekunatsa maitiro, imwe nzira inoreva kuti biological fermentation chigadzirwa caustic soda, yekunatsa ajenti uye mamwe makemikari, saka, inogona kudzikisa zvakanyanya kugadzirisa tsvina yemvura pH kukosha uye COD kukosha, iwo makemikari anoshandisa senge. zvinobudirira kutsiva yekunatsa mumiririri anogona kuita mune pretreatment tsvina COD kukosha kuchaderedzwa neinopfuura 60%.
"Biocomposite enzyme gadziriro ine hunhu hwemamiriro ekurapa akapfava, kushanda kwepamusoro uye kunaka kwakanaka.Iko kushandiswa kwebioenzyme kurapwa kune kukuvadza kushoma kune fiber yekotoni, uye ine inoshanda yekusvibisa mhedzisiro pane starch slurry uye PVA slurry pamucheka wegrey, inogona kuita yakanaka deizing maitiro. "Hunhu hwekotoni fiber inobatwa neiyi tekinoroji yakakwira zvakanyanya kupfuura iyo yemaitiro echinyakare, rwiyo rwakadaro.
Nezve mutengo wenyaya ine chekuita nemabhizinesi ekudhindisa uye kudhaya, rwiyo rwakakosha rwakataura kuti biocomposite enzyme chiitiko chakakwira, muyero wakaderera, mutengo wakafanana neakajairwa machira ekubatsira, haungawedzere mutengo wekugadzirisa, mazhinji emabhizinesi emachira anogona. zvigamuchire.Pamusoro pezvo, kushandiswa kwema enzymes ebhayoloji pakugadziriswa kunogona kuderedza zvakanyanya mutengo wekugadzirira uye kugadzirisa hupfumi hweindasitiri yemachira nekudzikisa kushandiswa kwesimba rehutsi, kubvisa mutengo wekuchenesa mvura yealkaline, uye kuderedza huwandu hweakasiyana makemikari AIDS. .
"Mukushandiswa kweenzymatic pretreatment tekinoroji yetianfang, iyo enzymatic pretreatment ye12,000 metres pure donje jira uye 11,000 metres aramid hot-wave cab inogona kuderedza mutengo ne30% ne70% zvakateerana zvichienzaniswa nemaitiro ealkaline.""Akadaro ding.
