Ukusetshenziswa kwezikhwama zepulasitiki ezilukiwe izinzuzo nemisebenzi kwaziwa kabanzi, ekukhiqizweni kwezikhwama eziningi zokuthenga ezinyatheliswa ngombala kanye nokusetshenziswa okuningi ngesikhathi esifanayo, izikhwama zepulasitiki ezilukiwe zokugcinwa okufushane okuvamile, ukubekwa kwemithetho evimbelayo nakho kuyadingeka ukuqonda, njengo-Ann kumele anciphise ukuguga kwezikhwama zepulasitiki ezilukiwe, andise ukusetshenziswa kokuphila?
Isikhwama esilukiwe sepulasitiki sakhiwe kakhulu ngesikhwama se-polypropylene kanye nesikhwama se-polyethylene. Ngokwendlela yokuthunga, sihlukaniswe ngesikhwama esingezansi sokuthunga, isikhwama esingaphansi sokuthunga esinobuhlalu, isikhwama esingaphansi sokuthunga esingasetshenziswanga. Manje sisetshenziswa kabanzi ekupakisheni okusheshayo, umanyolo, usimende, irayisi, imikhiqizo yamakhemikhali kanye nezinye izinto zokupakisha.
Ukuze kuhlolwe umsebenzi wokulwa nokuguga kwesikhwama sepulasitiki esilukiwe, singalinganiswa ngokuhlolwa kokuguga okusheshayo okwenziwe kanye nokuhlolwa kokumelana nesimo sezulu embonini yesikhwama esilukiwe sokuphrinta umbala.
Ukuhlolwa kokuguga okusheshayo kokwenziwa ukufaka isampula yesikhwama sepulasitiki esilukiwe emishinini yokuhlola, futhi ingabhekana nemiphumela yokukhanya, umoya-mpilo, ukushisa kanye nomswakama ngesikhathi esifanayo noma endaweni efanayo. Ngaphansi kwezimo ezinjalo, imingcele eyinhloko yemvelo ingaba eqinile futhi ilula, ngakho idatha etholiwe ingaba nokuphindaphindeka okuhle kakhulu.
Ngokusho kwe-ultraviolet engenhla esheshise ukuguga ngemva kokutholwa kwemikhiqizo efanelekile, ekusetshenzisweni kwangempela kwemvelo, umphumela wokulwa nokuguga uzohluka, ikakhulukazi uma kwenzeka ukwanda kwezinto zokugcwalisa ezivimbelwe yi-amine photosensitive agent, umphumela wayo wokulwa nokuguga awuzinzile.
Nakuba ukuhlolwa kokuchayeka ensimini kwezikhwama ezilukiwe kuthatha isikhathi eside futhi kudinga ukutshalwa kwezimali okukhulu kwabasebenzi kanye nezinsizakusebenza zezimali, idatha yokuhlola etholakele ngokuyisisekelo ihlangabezana nezidingo zokusetshenziswa ezisebenzayo futhi ingasetshenziswa ekuhlolweni kwekhwalithi yokulwa nokuguga kanye nokuqapha umphumela wokulwa nokuguga kwezikhwama ezilukiwe. Ekusetshenzisweni kwansuku zonke kwezikhwama ezilukiwe, izinga lokushisa elizungezile, umswakama, ukukhanya nezinye izimo zangaphandle zithinta ngqo impilo yezikhwama ezilukiwe. Ikakhulukazi ekubekweni ngaphandle, ukuhlasela kwemvula, ukukhanya kwelanga okuqondile, umoya, izinambuzane, izintuthwane kanye namagundane kuzosheshisa ukubhujiswa kwekhwalithi yamandla okudonsa ezikhwama ezilukiwe. Izikhwama zokulwa nezikhukhula kanye nokulawula izikhukhula, izikhwama zamalahle ezibekwe emoyeni ovulekile, njll., kufanele zicabangele ikhono lokulwa ne-ULTRAVIOLET lokulwa ne-oxidation lezikhwama ezilukiwe ngokwazo.
Izikhwama ezilukiwe ezisetshenziswa yimindeni noma izisebenzi kanye nabalimi kufanele zibekwe ngaphakathi endlini lapho kungekho khona ukukhanya kwelanga okuqondile, lapho kungekho khona isithukuthezi, futhi lapho kungekho khona izinambuzane, izintuthwane kanye namagundane. Ukuzifihla akuvunyelwe ngokuphelele.
