Kungani isikhwama esilukiwe se-PP sithandwa kangaka

Yini aIsikhwama esilukiwe se-PP?Abangane abaningi bayazi, kodwa abanye abangani abangakaze baxhumane naboIsikhwama esilukiwe se-PPAngazi okuningi,Lolu hlobo lwesikhwama yisikhwama esenziwe ngendwangu engalukiwe, esivame ukusetshenziselwa ukupakisha izinto noma ezinye izinjongo.Indwangu engalukiwe iwuhlobo lwendwangu engalukiwe, eyakhiwa ngokusetshenziswa okuqondile kwama-polymer chips, imicu emifushane noma imicu ukuze yakhe imicu ngokugeleza komoya noma inenetha lomshini.

Isisindo seIsikhwama esilukiwe se-PPkufana nesikhwama sephepha esivamile nesikhwama sepulasitiki, kodwa sithandwa yibo bonke ngenxa yokwenzeka kwayo, ubuhle nokuvikelwa kwemvelo.Isikhwama sokupakisha esingalukiwe sinezimpawu ezine ezilandelayo:

I. Umnotho

Kusukela ekukhululweni kwemikhawulo yepulasitiki, izikhwama zepulasitiki zaphuma kancane kancane emakethe yokupakisha, zathathelwa indawo.IIsikhwama esilukiwe se-PPayikwazi ukusetshenziswa ngokuphindaphindiwe kuphela, kodwa futhi namaphethini aphrintiwe kanye nezikhangiso kuwo.Ukusetshenziswa okuphindaphindiwe kwesikhwama kunezinga eliphansi lokulahlekelwa, elingakwazi ukugcina izindleko kuphela, kodwa futhi lilethe izinzuzo zokukhangisa.

II.ISAKHIWO

Impahla yesikhwama sokuthenga yendabuko ilula, kulula ukuphuka, igcina izindleko, ukuze iyenze ibe namandla, izobiza.Izikhwama zokupakisha ezingezona ezilukiwe zixazulula le nkinga, ukuqina okuhle, akulula ukuphuka.Ngaphezu kokuqinile, kodwa futhi nokungangeni kwamanzi, zizwe kahle, izici ezibukeka kahle, nakuba izindleko ziphezulu, kodwa impilo yesevisi yinde kakhulu.

III.Ukukhangisa

A enhleIsikhwama esilukiwe se-PP, akuseyona nje impahla, ukubukeka okuhle okungathandwa, kodwa futhi kungashintshwa kube isikhwama sehlombe esisodwa esilula semfashini, ngaleyo ndlela sibe indawo enhle.Izici eziqinile, ezingangeni manzi, nezinduku zesinyathelo nazo zizoba ukukhetha kokuqala kwamakhasimende, ngaphezu kwalokhoIsikhwama esilukiwe se-PPs ingaphrintwa kulogo noma ukukhangisa, ngaleyo ndlela ilethe umphumela wokukhangisa.

IV.Ukuvikelwa kwemvelo

Ukuze kuxazululwe inkinga yokuvikelwa kwemvelo, umyalo womkhawulo wepulasitiki ukhishwe, futhi ukusetshenziswa okuphindaphindiwe kwezikhwama zokupakisha ezingezona ezilukiwe kuye kwanciphisa kakhulu ukucindezela kokuguqulwa kwemfucumfucu, ngakho-ke inani elingaba khona alikwazi ukushintshwa ngemali, engakwazi ukuxazulula inkinga ukuthi ukupakisha okuvamile akulula ukululaza.
