Ib tug neeg soj ntsuam qhov sib txawv ntawm qhov kev siv tshuaj ntawm cov txheej txheem gravure thiab cov txheej txheem flexo nrog cov ntaub ntawv tseeb. Ntawm txoj kev xam qhov no, nws pom tau tias cov ntawv luam tawm flexo yog ib qho kev lag luam hauv nruab siab uas zoo rau kev luam ntawv thaum piv rau gravure printing.
Qhov hnyav noj ntawm ib lub tshuab luam ntawv gravure rau ib hnub yog li ntawm 5.544 tons.
Dab tsi yog qhov nyiaj ntawm cov organic hnyav emissions hauv cov txheej txheem gravure yog dab tsi? Ib cov ntaub ntawv qhia: 1 zaj duab xis gravure xovxwm nrog kev ceev ceev ntawm 300 m / min, ib qho kev khiav ntawm 20 xuab moos tauj ib hnub, ib zaj duab xis dav ntawm 1 m, thiab ib hnub tawm ntawm 360,000. Cov square meter yog xam los ntawm qhov nruab nrab ntawm cov xuab zeb siv ntawm 7 gram ib square meter (ntawv cim: nws yog ntub number case, tsis muaj kua mem qhuav), thiab nws xav haus 2520000 grams number case, uas yog 2.52 tons. Hauv cov txheej txheem gravure, nws yog ib qho tsim nyog kom kho cov tawv nqaij ntawm tus cwj mem xaj nrog qhov hnyav. Cov lus piv txwv yog 1: 2, uas yog, 1 kg ntawm tus number case yuav tsum tau 2 kg ntawm hnyav, uas muaj xws li ob leeg ntxiv hnyav ntxiv rau lub tev tus choj thiab qhov hnyav noj thaum ntxuav. Qhov kev hais haum yog ncaj qha ntsig txog rau ntawm qhov chaw tswj ntawm qhov chaw ua haujlwm. Feem ntau hais lus, kev tswj hwm theem siab yog siab, qhov hnyav noj yog me me, thiab lwm tus hloov dua siab tshiab. Yog hais tias peb xam raws li kev tswj theem ntawm lub tuam txhab, uas yog, qhov sib piv yog 1: 1.5, ces nws siv 3.78 tons ntawm hnyav thaum haus 2.52 tons ntawm number case. Vim tias cov ntsiab lus ntawm qhov hnyav hauv qhov hnyav yog tsis siab, 70% ntawm 2.52 tons ntawm tus lej yog hnyav, los yog 1.764 tons, xam ntawm 30%. Nyob rau hauv no txoj kev, qhov hnyav noj ntawm ib lub pob zeb gravure rau ib hnub yog siab li 5.544 tons. Cov ntaub ntawv no tsis yog txhob txwm tshaj tawm.
Qhov no yog vim hais tias: qhov kev luam ntawm 300 m / min tsis yog qhov siab tshaj plaws hauv cov tshuab luam ntawv loj, tsis hais qhov qhia txog ntau lub teb chaws loj-ceev gravure luam ntawv hauv cov kev lag luam gravure xyoo dhau los; lub sijhawm booting zoo 20 xuab moos hauv ib hnub tsis yog ntev tshaj plaws. Cov lag luam loj thiab nruab nrab ntawm cov chaw luam ntawv tsis nres thaum noj mov los yog hloov cov hauj lwm; 7 grams ntawm tus lej ntawm ib lub 'meter' meter yog tseem zoo, thiab lub tsev number case ntawm ib co gravure luam lag luam tau deb dhau qhov nqi, tab sis tsis muaj qhov kev txiav txim siab. Tshaj nkaus xwb; qhov nyiaj ntxiv hnyav ntxiv yog qhov tsawg tshaj li 1: 1.5, thiab kev tswj theem ntawm gravure printing yuav luag 1: 2. Tshaj tej ntawm, cov ntsiab lus ntawm qhov hnyav hnyav ntawm qhov hnyav yog twb tau siab tshaj los ntawm 30%. Qhov tseeb, cov ntsiab lus ntawm ntau lub hauv paus hauv plhaub yog tsawg dua 30% ntawm tag nrho, hauv ib qho lus, cov ntsiab lus hnyav ntawm 1 kg ntawm tus lej siab dua.
Lwm cov ntaub ntawv kuj siv tau los xyuas los ntawm sab nraud: Hauv qee cov tuam txhab gravure uas tau txhawj xeeb txog kev tiv thaiv ib puag ncig, cov nqi loj ntawm cov tshuaj hnyiab tau raug kho thiab siv, thiab cov txiaj ntsig zoo tsim los ntawm nws tau ua cov ntsiab tseem ceeb ntawm cov neeg ua haujlwm . Qee cov neeg nyob hauv txoj kev ua lag luam tau kawm txog ib lub chaw tsim khoom lag luam kom paub zoo thaum lub sij hawm. Cov khoom ntawm lub Hoobkas yog nyob rau qhov kawg ntawm lub khw muag khoom lag luam yooj yooj yim, nrog ib xyoo cov nqi tawm ntawm ntau pua lub vam, tab sis cov nyiaj muaj txiaj ntsig los ntawm cov hnyav ua dua tshiab, yog li ntawd lub tuam txhab tau xa Peb qhov tseem ceeb rau kev kho kom zoo dua qub thiab hloov cov khoom siv rov ua kom rov zoo, thiab txuas ntxiv mus tso nyiaj thiab hloov cov khoom ua kom rov zoo dua qub. Nrog ib lub nrooj ntawm tag nrho cov tsov txaij, cov organic solvents yuav tau tawm ncaj qha yam tsis muaj kev kho mob, thiab cov nyiaj emissions yuav loj loj!
Vim li cas thiaj li muaj cov txheej txheem ua kom muaj kev thaj yeeb zoo li thaj tsam ntawm tus phooj ywg?
Yuav ua li cas yog tias rooj plaub muab hloov rau cov txheej txheem flexo? Cov flexo cwj pwm zaj duab xis yog thinner, thiab cov xim hnyav ua kua flexo muaj ib cov xim piv rau ze dua ob npaug ntawm cov hnav khaub hlab, thiab cov ntsiab lus ntawm cov ntsiab lus yog me ntsis siab, kuj xam ntawm 30%. Cov square mis feem ntau yog 2 grams. Vim tias lub tshuab luam ntawv flexo luam tawm feem ntau yog siv lub qauv hauv cov qauv, txhua lub tshuab luam ntawv txais ib hom kaw ntiag tug, thiab tus number case nyob rau hauv lub lauj kaub tso rau hauv lub raj xa dej, uas yog qhib tag nrho zoo li tus number case tank ntawm lub tshuab luam ntawv gravure, hnyav yog volatilized. Tus nqi tsawg. Qhov piv ntawm flexo number case los hnyav yog feem ntau 1: 1, thiab lub tuam txhab nrog kev tswj theem siab dua tuaj yeem mus txog 1: 0.7. Rau kev xam qhov yooj yim, nws yog xam raws li 1: 1 ntawm no. Tseem nyob rau hauv raws li cov khoom noj hais saum toj no, qhov hnyav noj ntawm ib lub flexo xovxwm rau ib hnub tsuas yog 1.224 tons, uas yog 22% ntawm cov txheej txheem gravure printing. Nws tsis muaj qhov xav tias cov kuab tshuaj sib xyaws kuj raug siv. Kev lag luam yuav teev cov ntawv luam tawm flexo ua ib tus txheej txheem ntawm kev nyab xeeb, thiab gravure printing ua ib qho kev tsis-ib puag ncig. Yog hais tias cov ntaub ntawv luam tawm flexo luam ntawv siv dej raws li cov phom sij, qhov sib piv yog dab tsi? Cov txiaj ntsim tau xav txog.
Hauv 10 lub xyoo dhau los, gravure hnyav hnyav hauv thom khwm tau de-benzeneized, tab sis lawv tsis tuaj yeem tsim. Keeb kwm thiab kev muaj tiag tau ceeb toom peb tias cov hnyav hnyav hauv cov mos lwj yuav tsum muab hloov nrog dej-raws li cov phev, txawm tias muaj ntau yam teeb meem.
