Indlela yokukhetha indebe yePlastiki eLahliweyo?

Iikomityi zeplastiki ezilahlwayo zohlulwe ubukhulu becala zibe ziintlobo ezintathu ngemathiriyeli ekrwada

1. PET indebe

I-PET, i-1 yeplastiki, i-polyethylene terephthalate, esetyenziswa ngokuqhelekileyo kwiibhotile zamanzi amaminerali, iibhotile zesiselo ezahlukahlukeneyo kunye neekomityi zokusela ezibandayo. Kulula ukonakala kwi-70 ℃, kwaye izinto ezinobungozi emzimbeni womntu ziyanyibilika. Musa ukutshisa elangeni, kwaye ungafaki utywala, ioli kunye nezinye izinto.

2. PS indebe

I-PS, i-6 yeplastiki, i-polystyrene, inokumelana nokushisa malunga ne-60-70 degrees. Ngokuqhelekileyo isetyenziswa njengesiselo esibandayo. Iziselo ezishushu ziya kukhupha i-toxins kwaye zibe ne-brittle texture.

3. PP indebe

I-PP, i-5 yeplastiki, i-polypropylene. Xa kuthelekiswa ne-PET kunye ne-PS, ikomityi yePP yeyona nto idumileyo yesikhongozelo seplastiki, enokumelana nobushushu obuyi-130 ° C kwaye kuphela kwezinto zeplastiki ezinokufakwa kwi-oven microwave.

Xa ukhetha iikomityi zamanzi ezilahlwayo zeplastiki, chonga uphawu olusezantsi. No. 5 PP indebe ingasetyenziselwa zombini iziselo ezibandayo kunye nezishushu, kwaye No. 1 PET kunye No. 6 PS ingasetyenziselwa kuphela iziselo ezibandayo, khumbula.

Nokuba yikomityi yeplastiki elahlayo okanye ikomityi yephepha, kungcono ukuba ungayisebenzisi kwakhona. Iziselo ezibandayo nezishushu kufuneka zohlulwe. Amanye amashishini angekho mthethweni asebenzisa amaphepha asetyenzisiweyo asetyenzisiweyo kunye neeplastiki ezisetyenzisiweyo ukuze kuxhamle abanye. Kunzima ukubala konke ukungcola, kodwa iqulethe iindidi zesinyithi ezinzima okanye ezinye izinto ezinobungozi. Ngoko ke, kungcono ukhethe iimveliso ezivela kubavelisi abaqhelekileyo. Yintoni abathengi abaqhelekileyo abangayiqondiyo kukuba phakathi kweekomityi zeplastiki ezilahlayo kunye neekomityi zephepha, izinto zeplastiki ziphezulu kunephepha. Inokuqwalaselwa kwimiba emibini: 1. Inkqubo yokwenziwa kweekomityi zeplastiki ezilahlayo zilula, kwaye ucoceko lulula ukulawula. Iikomityi zephepha zintsonkothile, zineekhonkco ezininzi zemveliso, kwaye ugutyulo akulula ukulawula. 2. Ikomityi yeplastiki elahlayo esemgangathweni, engeyotyhefu kwaye ayinangcoliseko. Nkqu neekomityi zephepha eziqeqeshiweyo kulula ukwahlula imicimbi yangaphandle. Ukongezelela, izinto ezisetyenziselwa iikomityi zephepha zivela kwimithi, edla ubutyebi behlathi ngokugqithisileyo kwaye ibe nefuthe elikhulu kwindalo.
