1. Ngenxa yokuba ibhiya inezithako ze-organic ezifana ne-alcohol, kwaye iplastiki ekwiibhotile zeplastiki yeyezinto eziphilayo, ezi zinto ze-organic ziyingozi kumzimba womntu.Ngokomgaqo wokuhambelana okuneenkcukacha, ezi zinto ze-organic ziyakunyibilika kwibhiya.I-Toxic organic matter ifakwe emzimbeni, ngaloo ndlela ibangela ingozi kumzimba womntu, ngoko ke ibhiya ayipakishwanga kwiibhotile zeplastiki.
2. Iibhotile zeglasi zineenzuzo zeempawu ezintle zokuthintela igesi, ixesha elide lokugcina, ukucaca kakuhle, kunye nokuphinda kusetyenziswe kwakhona, kodwa kukho iingxaki ezifana nokusetyenziswa kwamandla aphezulu kwimveliso, ubunzima, kunye nokuqhuma okulula kunye nokulimala.
Kutshanje, uphuhliso kunye nophando lweebhotile ze-PET ezinezithintelo eziphezulu kunye nokupakishwa kwebhiya njengoko eyona nto kujoliswe kuyo iye yaba yindawo eshushu kushishino, kwaye inkqubela enkulu yenziwe emva kwexesha elide lomsebenzi wophando olubanzi.Ubhiya bubuthathaka kakhulu ekukhanyeni nakwi-oxygen, kwaye ubomi beshelufu buhlala bufikelela kwiintsuku eziyi-120.I-oxygen permeability yebhotile yebhiya iyadingeka ukuba ingabi ngaphezu kwe-1 × 10-6g kwiintsuku ze-120, kwaye ukulahlekelwa kwe-CO2 akukho ngaphezu kwe-5%.
Le mfuneko yi-2 ~ 5 amaxesha epropathi yesithintelo sebhotile ye-PET ecocekileyo;Ukongeza, ezinye ii-breweries zisebenzisa indlela ye-pasteurization yebhiya, efuna ukumelana nobushushu obuphezulu ukufikelela kwi-298 ℃, ngelixa amandla, ukumelana nobushushu, umqobo wegesi webhotile ye-PET ecocekileyo. ukubaleka ukuphanda nokuphuhlisa imathiriyeli entsha kunye neenkqubo ezintsha zemiqobo eyahlukeneyo kunye nophuculo.
Okwangoku, iteknoloji yokutshintsha iibhotile zeglasi kunye neetoti zetsimbi zebhiya kunye neebhotile ze-polyester zikhulile, kwaye inkqubo yokuthengisa iqalile.Ngokwengqikelelo yemagazini ye-"Modern Plastics", kwiminyaka emi-3 ukuya kwe-10 ezayo, i-1% ukuya kwi-5% yebhiya yehlabathi iya kuguqulwa ibe yi-PET ibhotile.
