Isikhwama esingalukiwe (esivame ukubizwa ngokuthi isikhwama esingalukiwe) siwumkhiqizo oluhlaza, oqinile futhi ohlala isikhathi eside, muhle ngokubukeka, ukungena komoya okuhle, ongasetshenziswa kabusha, uwasheke, ukukhangisa kwesikrini sikasilika, ukumaka, impilo ende yesevisi, efanele noma iyiphi inkampani, noma iyiphi imboni njengesikhangisi Sokukhangisa nezipho.Abathengi bathola isikhwama esihle esingalukiwe ngenkathi bethenga, futhi amabhizinisi athola okungcono kakhulu emhlabeni ngokukhangisa okungabonakali, ngakho izindwangu ezingalukiwe ziya ngokuya ziduma emakethe.
Izikhwama zokuthenga ezingalukiwe ziyizindwangu ezingalukiwe ezenziwe ngepulasitiki.Abantu abaningi bacabanga ukuthi indwangu iyimpahla yemvelo, kodwa empeleni kuwukungaqondi.Impahla eluhlaza esetshenziswa kakhulu yendwangu engalukiwe i-polypropylene (PP ngesiNgisi, evame ukubizwa nge-polypropylene) noma i-polyethylene terephthalate (PET ngesiNgisi, eyaziwa ngokuthi i-polyester).Impahla eluhlaza yezikhwama zepulasitiki i-polyethylene, nakuba amagama ezinto ezimbili ezifanayo., Kodwa ukwakheka kwamakhemikhali kuhluke kakhulu.Isakhiwo samangqamuzana amakhemikhali e-polyethylene sizinzile futhi kunzima kakhulu ukusehlisa, ngakho kuthatha iminyaka engu-300 ukuthi izikhwama zepulasitiki zibole;ngenkathi isakhiwo samakhemikhali se-polypropylene singenamandla, iketanga lamangqamuzana lingaphulwa kalula, elingase lihlehliswe ngokuphumelelayo , Futhi faka umjikelezo wemvelo olandelayo ngendlela engeyona enobuthi, isikhwama sokuthenga esingenalukiwe singachithwa ngokuphelele phakathi kwezinsuku ezingu-90. .Empeleni, i-polypropylene (PP) iwuhlobo olujwayelekile lwepulasitiki, futhi ukungcoliswa kwemvelo ngemva kokulahlwa kungama-10% kuphela ezikhwama zepulasitiki.
Umkhiqizo usebenzisa indwangu engalukiwe njengempahla eluhlaza.Kuyisizukulwane esisha sezinto zokwakha ezinobungani bemvelo.Inezici zobufakazi bomswakama, obuphefumulayo, obuguquguqukayo, isisindo esincane, esingashi, ukubola kalula, okungewona ubuthi futhi okungacasuli, okucebile ngombala, okuphansi kwentengo, nokuphinda kusetshenziswe kabusha.Impahla ingabola ngokwemvelo uma ibekwe ngaphandle izinsuku ezingama-90, futhi inempilo yesevisi efinyelela eminyakeni emi-5 uma ibekwe endlini.Ayinabuthi, ayinaphunga, futhi ayinazo izinto ezisele lapho ishile, ngakho ayingcolisi imvelo.Iqashelwa emhlabeni wonke njengomkhiqizo ohambisana nemvelo ovikela imvelo yomhlaba.
