Eminyakeni yamuva, izwi lokuvikelwa kwemvelo liya ngokuya likhuphuka, futhi izinqubomgomo ezihlukahlukene zokuvikela imvelo ziye zavela ngokungapheli, eziye zanwetshwa ngokujulile embonini yokunyathelisa, ikakhulukazi ukupakisha nokunyathelisa.Njengoba sazi, ama-VOC aguquguquka inqubo yokuphrinta ahlobene nokuqukethwe kwama-VOC kuyinki, i-solvent namakhemikhali ahlobene asetshenziswa，Kubuye kuhlobane nokushintshashintsha kwe-roller yepuleti kanye ne-inki roller ekuphrinteni, kanye nokushibilika kwe-semi. -iqedile ipuleti lokuphrinta kunqubo yokuphrinta.Amasethi ombala oweqile wemikhiqizo yokuphrinta nokuphrinta okugcwele ngokwemvelo kuzoholela ekwandeni kokuguquguquka kwama-VOC enqubweni yokuphrinta.
Ukulawula ama-VOC akuwona umsebenzi wokuphrinta kuphela.
Lokhu kukhishwa kwama-VOC kunezinkomba ezimbili ezibalulekile, enye ingqikithi yama-VOC ayinki, i-solvent namakhemikhali, enye iyisamba senani likayinki, izincibilikisi namakhemikhali asetshenziswa amabhizinisi afanelekile.Esimweni samanje, amabhizinisi afanelekile we-inki, ukulawulwa kokukhethwa kwamakhemikhali kuye kwaba nzima kakhulu, okuqukethwe kwe-VOCs bekulokhu kuphansi, kukhona amabhizinisi amaningi ngemuva kokwenza umsebenzi wesikole okwanele anganciphisa inani le-solvent lifinyelele umkhawulo, nakuba izinkampani zokunyathelisa ziye zazama. kanzima, lokhu kusetshenziswa okuphelele kuyigebe elingenakunqotshwa.
Esinye sezizathu ukunqunywa komklamo wokupakisha nokuphrinta.Njengamanje, amalebula emakethe ikakhulukazi ayiqembu elinemibala eminingi kanye nokuphrinta kohlelo olugcwele.Ingqikithi yokusetshenziswa kukayinki, i-solvent namakhemikhali ahlobene akuyona i-oda lobukhulu uma iqhathaniswa nokunyatheliswa kwezincwadi.Cabanga ngebhizinisi lokupakisha nokuphrinta, ukusetshenziswa kwaminyaka yonke kwamathani angama-40 kayinki wokuphrinta we-offset, amathani ayi-10 we-solvent, amathani ayi-5 wamakhemikhali ahlobene, ngokusho kokuqukethwe kwe-inki ye-VOCs okungengaphezu kuka-3% womkhawulo ongaphezulu, unyaka wokusetshenziswa kokukhiqiza. , okuqukethwe kukayinki VOCs kufinyelele amathani angu-1.2, kanye nezincibilikisi namakhemikhali ahlobene kuma-VOC, leli nani lizoba ngaphezulu.
Ukulawulwa kwama-VOC kufanele kuthathwe emthonjeni
Ngokuphrinta izidingo zenqubomgomo yokuvikelwa kwemvelo, ikakhulukazi ukukhishwa kwe-VOCs, umuzwa okwamanje usekungaqondini kahle, kugcizelelwa kakhulu ekulawuleni ukukhishwa kwezixhumanisi zokuphrinta.Izinqubomgomo ezehlukene zezemvelo nazo ziyibekela imingcele ngokuqinile inqubo yokuphrinta, yebo, uyinki namakhemikhali ahlobene ngokwezinga elithile.Kodwa noma ngabe ukusetshenziswa kwezinto ezingavuthiwe neziyisizayo ezivikela imvelo kuzokhiqiza inani elithile lama-VOC, noma ngabe ukusetshenziswa kwezinyathelo zokuphatha ezithuthukisiwe kungeke kube ukubusa okungu-100% kwama-VOC akhiqiziwe.
Ngakho-ke, izidingo zethu zokuvikelwa kwemvelo kokunyathelisa, hhayi kuphela ukucabangela ukuthi izinto ezisetshenziswayo zihambisana nemvelo, kodwa futhi ukuze sizuze ukuncipha okuyisisekelo, ukunciphisa okuhambisanayo kwezinto ezisetshenziswayo kusixhumanisi sokunyathelisa kuwukuphulukisa kuphela, impande yangempela nayo. kusixhumanisi sokuklama ilebula.Ngoba lokhu kuwumthombo wonke ukunyathelisa, ukukhiqizwa, lapho ukuklama ilebula ukunciphisa iqembu umbala, ukunciphisa ukunyathelisa okugcwele, kungaba ngokuyisisekelo kuzuzwe uyinki, i-solvent, amakhemikhali ahlobene ezifana ukunciphisa ngokuqondile imikhiqizo equkethe VOCs.
Sisebenza kanzima, kusukela kubaphathi be-VOC, ngisho nokukhishwa kwekhabhoni, kanye nokunciphisa ukukhishwa kwekhabhoni kungenza zombili izimpawu nezimbangela.
