A. Kuchuluka kwa ntchito
Muyezowu umatchula zofunikira pachitetezo cha chilengedwe cha pulasitiki, mapepala, nkhuni ndi zida zina zoyikapo zomwe zimagwiritsidwa ntchito pazinthu.
B. Zofunikira pachitetezo cha chilengedwe pakuyika zinthu
1. Chiwerengero cha zigawo za katundu wa katundu sichiyenera kupitirira zigawo za 3, ndipo chiwerengero chopanda kanthu sichiyenera kupitirira 40%;
2.Zinthu zonyamula katundu ziyenera kupangidwa ndi chinthu chimodzi momwe zingathere.
3. Chiwopsezo chonse cha lead, mercury, cadmium ndi hexavalent chromium pamapakedwe azinthu siziyenera kupitirira 100mg/kg;
4. Zomwe zili muzinthu zowonongeka (VOCs) mu inki zomwe zimagwiritsidwa ntchito popanga katundu ndi kusindikiza siziyenera kupitirira 5% (Kulemera);
5. Mitundu yosindikizira yomwe ikuwonetsedwa pamatumba apulasitiki sayenera kupitirira mitundu 6;
6. Kuyika kwa mankhwala a pepala kuyenera kupangidwa ndi zinthu zopitilira 75% zongowonjezwdwa za fiber;
7. Zida zopangira zida zamatabwa ziyenera kubwera kuchokera kunkhalango zongowonjezereka.
C. Njira zodziwira
1. Kuzindikira kuchuluka kwa zitsulo zolemera ( lead, mercury, cadmium, hexavalent chromium) m'mapaketi azinthu ndizogwirizana ndi GB/T 10004-2008, gwiritsani ntchito njira ya Mafilimu opangidwa ndi Pulasitiki ndi matumba kuti mutengere gulu lowuma komanso lopangidwa ndi extrusion. kupitiriza.
2. Kuzindikira kwa zinthu zosakhazikika za organic (VOCs) mu inki yomwe imagwiritsidwa ntchito posindikiza zinthu zopangira zinthu kumachitika molingana ndi njira yomwe yafotokozedwa mu GB/T 23986-2009, gwiritsani ntchito njira yakutsimikiza kwa zinthu zosasinthika (VOC) zomwe zili mu utoto ndi ma vanishi - Chromatography ya gesikupitiriza.
Zindikirani: Zomwe zili pamwambazi ndizomwe boma lathu likugwiritsira ntchito pazomwe mukugwiritsira ntchito.Tikuyembekezera miyezo / zofunikira zanu kuti mugwirizane.Kusindikiza kwa rotogravure, matumba ndi zikwama, zipangizo zam'madzi ndi zinthu zina zosinthika, chonde titumizireni kuti mudziwe zambiri.
