Kwiminyaka yakutshanje, ilizwi lokukhuselwa kwendalo likhula ngokunyuka, kwaye iinkqubo ezahlukeneyo zokukhusela indalo ziye zavela ngokungapheliyo, eziye zandiswa ngokunzulu kwishishini lokushicilela, ngakumbi ukupakisha kunye nokushicilela. Njengoko sisazi, ii-VOCs eziguquguqukayo yinkqubo yoshicilelo inxulumene nomxholo we-VOC kwi-inki, isinyibilikisi kunye neekhemikhali ezinxulumeneyo ezisetyenzisiweyo, ikwanxulumene nokuguquguquka kwe-plate roller kunye ne-inki roller kwinkqubo yoshicilelo, kunye nokuguquguquka kwesiqingatha semichiza. -igqityiwe ipleyiti yoshicilelo kwinkqubo yoshicilelo. Iiseti zombala ezigqithisileyo zeemveliso zoshicilelo kunye noshicilelo olupheleleyo luya kukhokelela ngokwendalo ekwandeni kwee-VOCs eziguquguqukayo kwinkqubo yoshicilelo.
Ulawulo lwee-VOCs ayingomsebenzi woshicilelo kuphela.
Oku kukhutshwa kwee-VOC kunezibonakaliso ezimbini ezibalulekileyo, enye ingumxholo opheleleyo we-VOC kwi-inki, i-solvent kunye neekhemikhali, enye yimali epheleleyo yeenki, i-solvents kunye neekhemikhali ezisetyenziswa ngamashishini afanelekileyo. Kwimeko yangoku, amashishini afanelekileyo kwi-inki, ulawulo lokhetho lweekhemikhali lube ngqongqo kakhulu, apho umxholo we-VOCs ube uphantsi ngokwentelekiso, kukho amashishini amaninzi emva kokwenza umsebenzi wesikolo owaneleyo unokunciphisa inani le-solvent ukuya kumda, nangona iinkampani zoshicilelo ziye zazama. nzima, oku kusetyenziswa ngokupheleleyo ngumsantsa ongenakoyiswa.
Esinye sezizathu kukunciphisa ukupakishwa kunye noyilo lokushicilela. Okwangoku, iilebhile kwimarike ikakhulu liqela lemibala emininzi kunye noshicilelo olupheleleyo. Itotali yokusetyenziswa kwe-inki, isinyibilikisi kunye nemichiza enxulumene noko ayilolungiselelo lobungakanani xa lithelekiswa noshicilelo lweencwadi. Khawucinge nje ngeshishini lokupakisha kunye noshicilelo, ukusetyenziswa konyaka kweetoni ezingama-40 ze-inki yokuprinta, iitoni ezili-10 ze-solvent, iitoni ezi-5 zeekhemikhali ezinxulumeneyo, ngokwe-inki ye-VOCs umxholo ongekho ngaphezu kwe-3% yomda ophezulu, unyaka wokusetyenziswa kwemveliso. , umxholo we-inki we-VOCs ufikelele kwiitoni ze-1.2, kunye ne-solvents kunye neekhemikhali ezinxulumene nazo kwii-VOCs, le mali iya kuba ngaphezulu.
Ulawulo lwee-VOCs kufuneka luthathwe kumthombo
Ukushicilela iimfuno zomgaqo-nkqubo wokukhuselwa kokusingqongileyo, ngakumbi ukukhutshwa kwee-VOCs, imvakalelo okwangoku ikukungaqondi kakuhle, kugxininiswa ngakumbi kulawulo lokukhutshwa kwamakhonkco okushicilela. Imigaqo-nkqubo eyahlukeneyo yokusingqongileyo ikwayithintele ngokungqongqo inkqubo yoshicilelo, ngokuqinisekileyo, i-inki nemichiza enxulumeneyo ukuya kumlinganiselo othile. Kodwa nokuba ukusetyenziswa kwezixhobo eziluhlaza kunye nezincedisayo ezihambelana nokusingqongileyo kuya kuvelisa inani elithile le-VOCs, nokuba ukusetyenziswa kwamanyathelo olawulo oluphezulu akunakuba yi-100% yolawulo lwee-VOC ezenziweyo.
Ngoko ke, iimfuno zethu kukhuseleko lokusingqongileyo yoshicilelo, kungekuphela nje ukuqwalasela ukuba izinto ezisetyenzisiweyo zihambelana nokusingqongileyo, kodwa ukuphumeza ukuncipha okusisiseko, ukucutha okuhambelanayo kwezinto ezisetyenziswayo kwikhonkco yoshicilelo kukuthomalalisa kuphela, ingcambu yokwenene nayo. kwikhonkco yoyilo lweleyibhile. Ngenxa yokuba lo ngumthombo yonke yoshicilelo, imveliso, xa uyilo ileyibhile ukunciphisa iqela umbala, ukunciphisa ushicilelo epheleleyo, ingakwazi ngokusisiseko ukufikelela inki, isinyibilikisi, imichiza ezinxulumene ezifana ukucuthwa ngqo iimveliso eziqulathe VOCs.
Sisebenza nzima, ukusuka kulawulo lwee-VOCs, kunye nokukhutshwa kwekhabhoni, kunye nokunciphisa ukukhutshwa kwekhabhoni kungenza zombini iimpawu kunye nezizathu ezisisiseko.
