Le mveliso yenziwe ngeilaphu elingalukwangaSisizukulwana esitsha sezixhobo ezinobuhlobo nokusingqongileyo. Ziyakwazi ukumelana nokufuma, ziyaphefumla, ziyaguquguquka, zilula, azitshi, kulula ukuzibolisa, azinatyhefu kwaye azicaphukisi, zinemibala emininzi, zixabiso liphantsi kwaye ziyaphinda zisetyenziswe.
Le nto inokubola ngokwendalo emva kokuba ibekwe ngaphandle kangangeentsuku ezingama-90. Inokuhlala ixesha elide ukuya kuthi ga kwiminyaka emi-5. Ayinatyhefu, ayinavumba kwaye ayinazo izinto eziseleyo xa itshisiwe, ngoko ke ayingcolisi okusingqongileyo kwaye yaziwa kwihlabathi liphela njengemveliso enobuhlobo nokusingqongileyo ekhusela indalo yomhlaba.
Iingenelo:
1. Ubunzima obulula: I-polypropylene resin yeyona nto iphambili esetyenziswayo ukuvelisa. Ubunzima obuthile yi-0.9 kuphela, ziinxalenye ezintathu kwezihlanu kuphela zomqhaphu, othambileyo kwaye uvakala kamnandi.
2. Ayinatyhefu, ayicaphukisi: Le mveliso iveliswa ngokwemigaqo ye-FDA yezinto ezikrwada zokutya, ayinazo ezinye izinto zeekhemikhali, isebenza kakuhle, ayinatyhefu, ayinavumba, kwaye ayilucaphukisi ulusu.
3. Iiarhente ezilwa neentsholongwane kunye neekhemikhali: I-Polypropylene yinto ethambileyo ngokweekhemikhali, engangeni zimpethu, kwaye inokwahlula iintsholongwane kunye nezinambuzane kulwelo. Iimveliso ezilwa neentsholongwane, ukubola kwe-alkali, kunye neemveliso ezigqityiweyo azichaphazeli amandla ngenxa yokukhukuliseka.
4. Iipropati ezilungileyo zomzimba: Yenziwa ngokujikelezisa i-polypropylene ngokuthe ngqo ibe yi-mesh, kwaye amandla emveliso angcono kunalawo eemveliso zefayibha eziqhelekileyo, amandla awo awakho kwicala, kwaye amandla obude kunye nawasecaleni ayafana.
5. Ngokuphathelele ukhuseleko lokusingqongileyo, izinto ezisetyenziswa kakhulu kwilaphu ezingalukwanga yipolypropylene, kwaye izinto ezisetyenziswa kwiingxowa zeplastiki yipolyethylene. Nangona ezi zinto zimbini zinamagama afanayo, zinezakhiwo zeekhemikhali ezahlukeneyo kakhulu. Ulwakhiwo lweemolekyuli zekhemikhali zepolyethylene luzinzile kakhulu kwaye kunzima kakhulu ukubola. Ke ngoko, kuthatha iminyaka engama-300 ukuba ingxowa yeplastiki ibole. Ulwakhiwo lweekhemikhali zepolypropylene alunamandla, kwaye uthotho lweemolekyuli lunokuqhekeka lula, ukuze lubole ngempumelelo. Kwaye kwimo engeyiyo ityhefu kumjikelo olandelayo wokusingqongileyo, iibhegi yokuthenga engalukwangainokubola ngokupheleleyo kwiintsuku ezingama-90. Ngaphezu koko, ingxowa yokuthenga engalukwanga inokusetyenziswa kwakhona izihlandlo ezingaphezu kwe-10, kwaye izinga longcoliseko lokusingqongileyo emva kokulahlwa li-10% kuphela yengxowa yeplastiki.
