Cov npe tshuaj uas nws txwv tsis pub sib tshooj nrog cov khoom tseem ceeb rau PVC, yog li daim ntawv tshaj tawm RoHS muaj qee cov ntaub ntawv muaj txiaj ntsig, tab sis nws tsis yog txoj cai siv rau cov khoom siv hauv tsev. Qhov twg PVC yog ib feem ntawm cov khoom siv hluav taws xob, txoj hauj lwm thim rov qab.
Puas yog Proposition 65 txwv tsis pub muaj npe tshuaj?
Tsis yog. Nws yuav tsum tau ceeb toom kom meej thiab tsim nyog ua ntej nthuav tawm ib tus neeg rau cov tshuaj uas tau teev tseg saum toj ntawm qhov chaw nres nkoj nyab xeeb. Ib yam khoom uas muaj cov khoom teev tseg tsis raug txwv tsis pub muag, yog tias yuav tsum tau ceeb toom. Qhov twg ib qho kev qhia tshwj xeeb hais txog kev ua raws li Txoj Cai 65, nws tsim nyog los tsim seb lub hom phiaj yog kev ceeb toom, qhov pib, lossis lwm yam, vim tias txoj cai xa tawm thawj zaug.
Puas yog XRF xeem ua pov thawj txwv tsis pub ua raws li cov tshuaj?
Tsuas yog rau cov khoom nws tuaj yeem ntes tau. Elemental tshuaj ntsuam xyuas yog siv tau rau txhuas, cadmium, mercury, chromium thiab bromine, thiab dig muag rau txhua yam organic. Phthalate plasticisers thiab feem ntau cov neeg sib tw npe tshuaj yog cov organic, yog li lub vijtsam tseem ceeb hais tsis muaj dab tsi txog lawv. Rau qib hloov tau yooj yim, uas yog qhov tseeb qhov chaw raug tso, uas ua rau cov ntsiab lus tshwm sim tsis tiav cov lus teb tsis yog kev tshem tawm.
Cov qib PVC twg muaj txoj haujlwm yooj yim tshaj plaws?
Rigid qib uas tsis muaj plasticiser, calcium -zinc stabilizer system thiab tsis muaj cadmium los yog lead raws li pigments. Plasticiser yog qhov sib txawv loj tshaj plaws, thiab cov khoom siv nruj tsis muaj, uas tshem tawm tag nrho cov khoom tsis muaj nqi ntxiv lossis ua tiav. Tsis tas li ntawd, cov khoom siv ntxiv tau txiav txim siab cov lus teb, uas yog vim li cas cov formulation tseem ceeb tshaj cov khoom tsev neeg.
Kev hloov xim puas cuam tshuam rau kev tshaj tawm ua raws?
Nws tuaj yeem ua tau, thiab daim ntawv yuav tsum tau muab rov qab yog tias nws ua. Xim yog ntxiv raws li ib tug masterbatch, uas yog ib tug cais formulation nrog nws tus kheej pigments thiab nqa. Cadmium thiab lead raws pigments yog qhov kev txhawj xeeb tseem ceeb, thiab lawv tau siv los tsim cov xim muaj zog. Ib daim ntawv tshaj tawm uas tau tshaj tawm rau qib tsis muaj pigmented tsis tuaj yeem txuas mus rau cov xim xim ntawm nws.
Kuv yuav thov dab tsi raws li qhov tsawg kawg nkaus?
Daim ntawv tshaj tawm npe ntawm cov kev cai, cov qauv ntawm cov npe khoom nrog hnub tim, txawm tias lub hauv paus yog cov ntaub ntawv xov xwm lossis kev sim, cov qib tshwj xeeb thiab xim npog, nws tau tshuaj xyuas ntau npaum li cas, thiab nws tsis npog. Cov khoom kawg yog qhov yuav luag tsis tau muab thiab ib qho uas tiv thaiv kev nkag siab yuam kev feem ntau tom qab.
Nug rau Txoj Cai, Tsis Yog Daim Ntawv Sau
Qhia rau peb paub qhov chaw ua lag luam, daim ntawv thov thiab qib uas koj tab tom txiav txim siab, thiab peb yuav paub meej tias cov khoom siv txwv tsis pub siv thiab cov pov thawj dab tsi peb tuaj yeem muab tawm tsam nws.
