Nguwuphi umahluko phakathi kwezinto ze-PS kunye nezixhobo ze-AS zeekomityi zamanzi zeplastiki

Ziziphi izinto ezisetyenziswayo ngoku kwiikomityi zamanzi zeplastiki kwiimarike, ezifana ne-Tritan, i-PP, i-PPSU, i-PC, i-AS, njl njl. I-PS ayifane ikhankanywe njengezinto eziqhelekileyo kwiikomityi zamanzi zeplastiki. Ndaye ndadibana neemfuno zokuthenga zomthengi waseYurophu. Umhleli wayenofikelelo kwizinto ze-PS. Abahlobo abaninzi ababandakanyeka kurhwebo lwangaphandle bayazi ukuba yonke imarike yaseYurophu, njengeJamani, inyanzelisa imiyalelo yothintelo lweplastiki. Isizathu kukuba izinto zeplastiki akulula ukubola kunye nokuphinda zisetyenziswe, kwaye izinto ezininzi zeplastiki ziqukethe i-bisphenol A, enokubangela ingozi kumzimba womntu emva kokuba yenziwe kwiikomityi zamanzi. Ngokomzekelo, izixhobo ze-PC, nangona zingcono kune-AS kunye ne-PS kwezinye iinkalo zokusebenza, zivaliwe kwimarike yaseYurophu ukuveliswa kweebhotile zamanzi kuba ziqulethe i-bisphenol A.

I-PS, ngokwemiqathango ye-layman, yintlaka ye-thermoplastic engenambala kwaye ecacileyo kunye nokuhanjiswa okuphezulu. Xa kuthelekiswa nezinto zeplastiki ezikhankanywe ngasentla, ixabiso layo eliphantsi liyinzuzo yalo, kodwa i-PS ibuthathaka kwaye inobunzima obunzima, kwaye le nto iqulethe iikomityi zamanzi eziphindwe kabini ezenziwe ngephenol A kunye ne-PS izinto azikwazi ukuzaliswa ngamanzi ashushu aphezulu, ngaphandle koko. baya kukhupha i-bisphenol Aharmful substances.

I-AS, i-acrylonitrile-styrene resin, i-polymer material, engenambala kunye ne-transparent, ene-transmittance ephezulu. Xa kuthelekiswa ne-PS, ixhathise ngakumbi ukuwa, kodwa ayinakuhlala ixesha elide, ngakumbi ayixhathisi ukuhluka kweqondo lokushisa. Ukuba ukongeza ngokukhawuleza amanzi abandayo emva kwamanzi ashushu, umphezulu wezinto eziphathekayo uya Ukuba kukho ukuqhekeka okucacileyo, kuya kuphinda kuqhekeke xa kufakwe efrijini. Ayinayo i-bisphenol A. Nangona ukuyizalisa ngamanzi ashushu kuya kubangela ukuba indebe yamanzi iqhube, ayiyi kukhulula izinto ezinobungozi, ngoko inokudlula uvavanyo lwe-EU. Iindleko zezinto eziphathekayo ziphezulu kune-PS.
Indlela yokugweba kwimveliso egqityiweyo ukuba indebe yamanzi yenziwe nge-PS okanye i-AS impahla? Ngokuqwalasela, kunokubonwa ukuba ikomityi yamanzi engenambala kwaye ecacileyo eyenziwe ngezi zinto zimbini iya kubonisa ngokwendalo isiphumo esiluhlaza. Kodwa ukuba ufuna ukufumanisa ngokuthe ngqo ukuba yi-PS okanye i-AS, kufuneka usebenzise izixhobo zovavanyo lobuchwephesha.
