Iikomityi zamanzi zeplastiki zithandwa ngabantu abaninzi, ngakumbi abantwana, ulutsha, kunye nabantu abathanda ngaphandle, abanjengoomatshini bezolimo, abasebenzi bokwakha, kunye nabasebenzi bokwakha, ngenxa yeemilo zabo ezahlukeneyo, imibala eqaqambileyo, amaxabiso aphantsi, kunye nendalo engonwabanga.Iingcali zikhumbuza ukuba ukusetyenziswa kwexesha elide kweekomityi zamanzi zeplastiki akukhuselekanga kumanzi okusela, kwaye akukhuthazwa ukusebenzisa iikomityi zamanzi zeplastiki.Izizathu zezi zilandelayo:
Okokuqala, iiplastiki zizinto zemichiza yePolymer, zihlala zinemichiza eyityhefu efana nepolypropylene okanye iPVC.Ukusela amanzi kwikomityi yeplastiki ngokuqinisekileyo kusetyenziselwa ukugcina amanzi ashushu okanye amanzi abilayo.Xa usebenzisa iikomityi zamanzi zeplastiki ukubamba amanzi ashushu, ingakumbi amanzi abilisiweyo, imichiza eyityhefu ekwiplastiki inokuphumela lula emanzini.Ukusela amanzi anjalo ixesha elide kuya kubangela ingozi kumzimba womntu.
Okwesibini, iikomityi zamanzi zeplastiki ziqhelekile kwiibhaktheriya kwaye akukho lula ukuzicoca.Oku kungenxa yokuba iplastiki ebonakala inomphezulu ogudileyo ayigudi, kwaye zininzi iipores ezincinci kwi-microstructure yangaphakathi.Ezi pores zincinci zixhomekeke kukungcola kunye nokulinganisa, kwaye azikwazi ukucocwa ngokusebenzisa iindlela eziqhelekileyo.
Okwesithathu, iikomityi ezininzi zamanzi zeplastiki ezithengiswa kwimarike zenziwe nge-polycarbonate, kwaye i-bisphenol A yenye yezinto eziphambili zokuvelisa iiplastiki ze-polycarbonate.I-Bisphenol A yamkelwa kumazwe ngamazwe njengento enokonyusa umngcipheko womhlaza, kwaye inxulumene nomhlaza wamabele, umhlaza wedlala lobudoda kunye nokufikisa kwangaphambili.Ukwenzakala kwayo emzimbeni womntu kuyafana nokutshaya.Emva kokungena, kunzima ukubola, kunomphumo wokuqokelela, kwaye unokudluliselwa kwisizukulwana esilandelayo.Ngokutsho kovavanyo olwenziwa yiHarvard School of Public Health eUnited States, ukusela iziselo kwiibhotile zeplastiki nokutya ukutya okugcinwe kwiibhotile zeplastiki yeyona mithombo iphambili yebisphenol A emzimbeni womntu.
