Gulu la chilengedwe

Chifukwa cha ntchito ya stabilizer, plasticizer ndi fillers zosiyanasiyana ndi zina anawonjezera zinthu zachilengedwe mbali zosiyanasiyana ndi osiyana.Nthawi zambiri, zimayesedwa ndi njira zodziwira ndi miyezo ya ROHS kapena REACH.Amagawidwa muchitetezo cha chilengedwe komanso chitetezo cha PVC chopanda chilengedwe.

Chitetezo cha chilengedwe

Zida zama chingwe zoteteza chilengedwe, ndiye kuti, zida zikakonzedwa bwino, zimayesedwa pazida zoyezera za ICP molingana ndi njira zodziwira ndi miyezo ya ROHS kapena REACH.Zomwe zili muzitsulo zolemera,DEHP, nonylphenol, polybrominated biphenyls ndi zinthu zina zoletsedwa ndi zinthu zoyendetsedwa muzinthu zonse zakuthupi sizikhala ndi kuchuluka kwa ndalama.Chifukwa cha miyezo ndi zofunikira zosiyanasiyana za dziko lililonse, miyezo yofananira ya chilengedwe ndi yosiyana.Mayunitsi oyeserera nthawi zambiri amayesedwa mu PPM.

The stabilizer wa chilengedwe chitetezo chingwe zinthu zambiri ntchito calcium ndi nthaka stabilizer.

Chofunikira kwambiri pazida za chingwe cha PVC zomwe zimakwaniritsa mulingo wa REACH ndikuti zinthu za DEHP16 sizingagwiritsidwe ntchito ngati mapulasitiki.

Chitetezo cha chilengedwe

Zipangizo za chingwe zoteteza zachilengedwe zomwe siziteteza chilengedwe nthawi zambiri zimagwiritsa ntchito mchere wamchere ngati chokhazikika, chifukwa zimakhala ndi lead zitsulo zolemera, chromium, cadmium, mercury, barium ndi zitsulo zina zolemera, zingayambitse kuwonongeka kwakukulu kwa chilengedwe komanso thanzi la anthu, ndipo mayiko ambiri amaletsa kapena kuletsa kugwiritsa ntchito.
