Iimveliso zePlastiki, njengezinto eziyimfuneko kwishishini lanamhlanje kunye nobomi bemihla ngemihla, zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ngenxa yeenzuzo zazo zokusebenza ezizodwa. Ukusebenza kwabo kubonakaliswa ngokuyintloko kumzimba wabo, iikhemikhali, kunye neepropathi zokucubungula, ezithi xa zidibene zigqibe umda kunye nexabiso leplastiki.
Ngokwenyama, iiplastiki zibonakaliswa ngobunzima obulula kunye namandla aphezulu. Ngelixa uxinano lweplastiki ezininzi inye kuphela-ikota ukuya kwenye{2}}yesibhozo yesinyithi, iindlela zokulungisa (ezifana nokuqinisa ifayibha okanye izihluzi zeminerali) zingaphucula kakhulu iimpawu zabo zoomatshini, okukhokelela kumthwalo ogqwesileyo{3}}ukuthwala nokunxiba{4}}ukumelana nokusebenza. Ngaphaya koko, iiplastiki zibonelela ngeempawu ezigqwesileyo zokugquma, zizenza izinto eziyimfuneko kwiimveliso zombane nezombane. Ngokomzekelo, i-polyethylene (PE) kunye ne-polypropylene (PP) isetyenziswe ngokubanzi kwi-insulation of wires kunye neentambo ngenxa yeempawu zabo ze-dielectric ezigqwesileyo.
Ngokubhekiselele kwiipropathi zeekhemikhali, iiplastiki zixhaphake ngokuxhathisa ukubola kunye nokuguga. Ngokungafaniyo neentsimbi, ezinokuthi zichaphazeleke kwi-asidi kunye ne-alkali corrosion, iiplastiki zizinzile kwiindawo ezinobungozi beekhemikhali kwaye ke zisetyenziswa ngokuqhelekileyo kwizixhobo ezifana nemibhobho yekhemikhali kunye neetanki zokugcina. Nangona kunjalo, ezinye iiplastiki, ezifana ne-polystyrene, ziyakwazi ukuthotywa phantsi kwexesha elide lokuvezwa kokukhanya kwe-ultraviolet, nto leyo efuna ukongezwa kwezizinzisi ukuphucula ukumelana nemozulu. Ukuqhubekeka kolunye uncedo olukhulu lweeplastiki. Iiplastiki zinokubunjwa ngeenkqubo ezahlukeneyo, kubandakanya ukubunjwa kwenaliti, i-extrusion, kunye nokubunjwa kokuvuthela, ukuziqhelanisa noyilo oluntsonkothileyo olunobuchule obuphezulu kunye neendleko eziphantsi. Ngokomzekelo, i-thermoplastics inokufudumeza ngokuphindaphindiweyo ukuthambisa, okwenza kube lula ukuphinda isetyenziswe kwaye ihambelane neemfuno zophuhliso oluzinzileyo.
Nangona ukusebenza kakuhle kweemveliso zeplastiki, ubuhlobo babo bendalo buhlala buyinto ephikisanayo. Impumelelo yexesha elizayo kwi-bio{1}esekwe kuphando lwemathiriyeli kunye nophuhliso kunye nobuchwepheshe bokurisayikilisha zithembisa ukunciphisa ngakumbi impembelelo ye-ikholoji yeeplastiki ngelixa zigcina ukusebenza kwazo okuphezulu. Ngokubanzi, ukusebenza kweemveliso zeplastiki kuzenza zibe yimathiriyeli ebalulekileyo exhasayo kuphuhliso loluntu lwanamhlanje.
