Wake wacabanga ukuthi ipulasitiki yenziwa kanjani? Kuyinqubo ethakazelisayo! Konke kuqala ngohlobo olukhethekile lwezinto ezibizwa ngokuthi ama-polymer. Ama-polymer ayizinhlanganisela ezinde zezingcezu ezincane ezibizwa ngokuthi ama-molecule. Amanye ama-polymer avela emvelweni, njengalawo esiwabona ezitshalweni, kuyilapho amanye enziwa ososayensi ema-laboratory ngenqubo ekhethekile ebizwa ngokuthi i-polymerization. Lapho-ke lapho izingcezu ezincane zihlangana zibe imicu emikhulu.
Amanomoni amahlukene aninzi okulandelwa ngamakhulu ababekhetha ukuyongeza kwiimepholimari ezidingezwe. Amanomoni akhuphe amanqaku angaphakathi, ngoba bayingeni ukufika ngeemoli zonke izinto, njengeesithombe esingafuneka ukuze ufikelele ngendlela engasenziyo. Ngokukhetha amanomoni amaningi nokuyongeza kubanye nalokugcineni, ababekhetha bazokwenza umbango omncane wokuvela kwedabi edingekayo. Kuzo kusetyenziswa ngazo kuminingi emibhalweni, phakathi kweentoyi, iikonteyinir, kunye neemakhadi yamashumi aselula, ngoba ngalokho lokuhlala kweephrojela eliphakamisileyo.
Kunezinye izincwadi ezidinga ukufakwa kweplastik ngonyaka, futhi bavumelelwa ngeemkhakha engaphezulu. Amacala amabili osebenzisi kakhulu ayiqinileyo neephetroleumi ehlukene phakathi kweDibhali, umoya wendawo, ubhiyikho kunye namanye amacala amahluke aqinileyo njengo mahashi nezisobhu. Amacala amanje amahluke ngokuthi abesetyenziswa ukusuphesha iimikhakha ezidinga ukufakwa kweplastiki. Ukubuyiselwa kweamacala amangaphambili emangamnyama kulo plasti kuqhutyentlwano lokusebenza noma isiliso sasendle kunye nosizo!
Amanqaku apho angenzi iplastiki akhutshelwa kwezinto ezifanyane nezingca zokuthengisa. Amaxesibhenzisi abaningi ngezinto eziyizamanje. Kufuneka bayekho amandla kunye nokuhlola, okungakho ukuba zingatshonalendawo lomngeni lokugcina kunye nokukhathalika. Lokhu kuhluke ngokushesha ngoba iplastiki inikwe emuva yezinto ezinikezeliyo kwindawo yokusukela, kwiindlebe zemanzini kwi-toys. Ukubhala konke izinto ezidinga ukuhlola lokhu kuzobuyisela iiplastiki engayazi njalo — bavakalayo, babonakalayo kunye nokusetshenziswa kwindawo ezininzi.
I-Resin: Lento lenkululeko leliplastiki (kakhulu), kunye nokudibanisana ngezinye izigaba ze-resin. Kunezigaba eziningi ze-resin nesintle esikhundleniwe, futhi kunokuthi zihlukaniseleleyo ngokwesicwangciso sokusetshenziswa kunye nokuphumelela, ngakho ke kufuneka zisetshenziswa ngokupheleleyo ngokwesigaba sasinye phakathi kwazo.
Izithasiselo: Izinto ezengeziwe ezifakwa emapulasitiki ukuze kuthuthukiswe izakhiwo zawo. Izithako ezivamile yizinhlobonhlobo zombala ezenza ipulasitiki ibe nombala, iziqinisi ezisiza ipulasitiki ukuba ihlale isikhathi eside elangeni nezithambisi ezenza ipulasitiki ibe mnene futhi ihlale ithambile.
Izithako: Izithako ziyizinto eziqinisa ipulasitiki ziyenze iqine. Zihlanganisa izikhala zepulasitiki futhi ziyincede igcine ukuma kwayo. Izithako ezivame kakhulu zokugcwalisa yizintambo zengilazi, ezinikeza amandla, izintambo zikagesi nezinye izinto eziwusizo ezingashintsha ukuzwela noma isisindo sepulasitiki.
