Ngowuphi umahluko phakathi kwemathiriyeli ye-PS kunye nempahla ye-AS yeekomityi zamanzi zeplastiki?

Kumanqaku angaphambili, umahluko phakathi kwezinto zeplastiki zeiikomityi zamanzi zeplastikizichaziwe, kodwa uthelekiso oluneenkcukacha phakathi kwe-PS kunye ne-AS imathiriyeli ibonakala ingachazwanga ngokweenkcukacha.Ukuthatha inzuzo yeprojekthi yakutshanje, sithelekise izixhobo ze-PS zeekomityi zamanzi zeplastiki kunye Makhe ndihlanganyele nawe umahluko wezinto ze-AS.

Ngaphambi kokwabelana, makhe ndabelane ngeengcinga zam zobuqu ngokubhala amanqaku malunga neekomityi zamanzi kule minyaka idlulileyo.Saqala ukubhala amanqaku malunga neekomityi zamanzi kwi-2022. Ukususela ekubhaleni okungaqhelekanga ukuya kuthi ga ngoku, sinokuyihlalutya ngokubanzi kunye nesayensi kubahlobo bethu.Ekubhaleni amanqaku kule minyaka idlulileyo, ndiye ndazuza lukhulu, kodwa ukubhala kuyadika kwaye kuyadika.Ukususela kwintlungu yokungakwazi ukubhala amanqaku aqondakalayo kwaye atyebileyo ekuqaleni, kwintlungu yokungakwazi ukubhala inqaku elinye yonke imihla njengemihla yokuqala.Inani labahlobo abasilandelayo liya lisanda ngokuthe ngcembe.Amanye amanqaku atyhalwa ngokwendalo ngenxa yomgangatho wawo ophezulu, kodwa kusekho amanqaku amaninzi angacetyiswayo.Sinethemba elinyanisekileyo lokuba abahlobo abathanda ukwabelana ngamanqaku kwiwebhusayithi nabanokunceda ngamanqaku baya kusilandela.iwebhusayithi, kwaye usincede ukwabelana ngamanqaku ocinga ukuba axabisekile ukuze abahlobo abaninzi bawabone.Ngenxa yokudinwa kwezinto zokudala apha, ndiyathemba kwakhona ukuba wonke umntu uya kubuza omnye umbuzo kunye nempahla malunga neekomityi zamanzi kunye neeketile.Ndibulela kakhulu ngenkxaso yenu.

Kwinqaku elidlulileyo, ndikhankanye ukuba zeziphi izinto ezisetyenziswayo ngoku kwiikomityi zamanzi zeplastiki kwiimarike, ezifana ne-Tritan, PP, PPSU, PC, AS, njl. I-PS ayifane ikhankanywe njengento eqhelekileyo kwiikomityi zamanzi zeplastiki.Ndaye ndadibana nomnye abathengi baseYurophu badibana nezixhobo ze-PS kwiimfuno zabo zokuthenga.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 elincinci liyinzuzo yalo, kodwa i-PS i-fragile kwaye inobunzima obunzima, kwaye le nto iqulethe iikomityi zamanzi eziphindwe kabini ezenziwe nge-phenol A kunye ne-PS izinto azikwazi ukuzaliswa ngamanzi ashushu aphezulu, ngaphandle koko. baya kukhupha i-bisphenol A izinto eziyingozi.

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 kumahluko obushushu.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.
