Niaj hnub no, cov kev pabcuam luam ntawv tau nrov heev hauv ntau qhov kev lag luam: phau ntawv, nplooj ntawv thiab offset luam ntawv yog qhov xav tau thoob plaws ntiaj teb.
Kev lag luam luam ntawv siv ntau qhov sib txawv thiab cov khoom siv hauv nws cov haujlwm. Cov peev txheej thiab cov khoom siv no tau siv ntau heev, ua rau muaj kev cuam tshuam tsis zoo. Cov no tuaj yeem yog ornaments, tshem tawm, pleev xim, tsim tawm, rags, thiab lwm yam.
Cov khib nyiab xws li cov ntawv pov tseg yog qhov tsis tuaj yeem zam tau vim tias cov ntaub ntawv pov tseg yuav muaj cov khoom tsis zoo rau ib puag ncig, xws li tshuaj lom neeg hauv cov xim hauv cov ntaub ntawv luam ntawv.
Kev pov tseg ntawm kev luam ntawv pov tseg
Sau cov khib nyiab rov ua dua uas muaj cov khoom kho thiab tsim tawm, thiab rov qab cov nyiaj sib txuas los ntawm nws.
Cov kua roj vanish thiab luam ntawv tus lej suav txog li 5% ntawm tag nrho cov pov tseg, tab sis lawv yuav cuam tshuam rau cov txheej txheem rov ua dua tshiab. Thaum cov ntawv siv rov ua dua tshiab, deinking yuav tshwm sim, tab sis cov pov tseg yuav raug cais raws li hom ntawv ua ntej. Tom qab crushing nyob rau hauv rhuab dej alkaline nruab nrab. Tshem cov xim los ntawm kev sib cais ntawm cellulose fibers. Cov khoom siv rov ua dua tshiab yog siv los ua cov khoom siv rov ua dua tshiab rau kev tsim cov duab los qhia thiab ntawv.
Thaum luam ntawv nrog ib puag ncig-phooj ywg number case, cov khib nyiab tuaj yeem siv ua chiv.
Kev tshem tawm ntau yam dyes los ntawm kev luam ntawv pov tseg yog nyob ntawm qhov xwm txheej ntawm dyes:
Cov qauv sib txuas ntawm cov toner thiab UV number case ua rau lawv tsis yooj yim tshem tawm.
Mineral oil based paints thiab hnyav raws li cov xim tuaj yeem tshem tawm tau yooj yim.
Cov roj zaub yuav cuam tshuam cov xim tshem tawm vim oxidative polymerization.
Txhawm rau ua kom tiav, peb tuaj yeem txiav txim siab tias cov ntaub ntawv zoo ib puag ncig thiab nyab xeeb dua, cov txheej txheem rov ua dua yuav yooj yim dua.
Kev kho cov ntawv pov tseg
Niaj hnub no, cov txheej txheem hauv qab no yog siv los daws cov ntawv pov tseg:
Kev ua haujlwm;
Crush (txiav);
Hlawv.
Safe Disposal Technology of Printing Waste
Cov khib nyiab tsim los ntawm kev lag luam luam ntawv yog hloov cov ntaub ntawv raw xws li cellulose, ntoo thiab pulp.
Lub tshuab pov tseg kev nyab xeeb ntawm kev luam ntawv pov tseg txhais tau tias yog ob-theem ntub dej ntxuav cov ntaub ntawv, kom cov khib nyiab tuaj yeem siv los tsim cov ntawv thiab cov duab los qhia.
Technology muaj xws li cov haujlwm hauv qab no:
Cov ntaub ntawv pov tseg - hauv hydraulic diluent, pov tseg yog crushed thiab decomposed rau hauv fibers;
Tshem tawm ntau yam impurities los ntawm cov ntawv pov tseg;
Ntxiv decomposition ntawm pov tseg rau hauv fibers;
Kev tu zoo tab tom ua.
