Sawubona, abafowethu! Ngosuku lwesibini, sizofunda ngenkinga lokubonisa ukuthi zonke izinto zingasetyenziswa ukwenza imayiphi. Sibona imayiphi ngendawo eyona kunesikhatsi esikhulu. PLACEHOLDER-ENDSYSTEM Sibona ukuthi kudinga ukwenzela ukuthi siyazi ukuba phansi kanjani lemilenzele yemayiphi kunye nokuthi ifundekayo. Ngakho ke, ngaphandle kwezinye izinsiza, vuma ngalokho sibalele kule ndaba elitshele!
I-plastic iyishintshwale eshiyekelwa ngeminyaka eminingi elizama lokulandelwa, kodwa ezindleni zokungena kakhulu ziyi-crude oil kunye ne-natural gas. Leli lula yamatirhali ahlukile ngoba kukho okuthi uhlamvu wakhe wonke umkhuhlane we-hydrocarbons. Lokhu kulula ngokuba i-hydrocarbons izivele ezidinga ukusetyenziswa kwe-plastic. Umsebenzi oluzama uluhlola ukusetshenziswa kwesi plastic isebenza njengomsebenzi wesigodlo esimiswe nge-polymerization. Umsebenzi omncane ongqo ophambili le nto uphinda amahhweba angama-hydrocarbons ngokuphambili kwi-polymers. Amahhweba amaphambili amaningi amalungelelanisi kwalendawo yokugcina kanye nokubhedelela kwalendawo lesi plastic, oku kuyinto engazange libe lokuqinisekileyo kanye nokubhedelela, lokunye nokuba yilokhu luchasene nesiphumo sokuqinisekisa.
Manje, ngizobhekisa amonotha. Amonotha ayiqinile ezilindezelana ukwenzela iplastiki. Ungahambisana nge-amonotha nalokho nakwesihlanu labo legumbi elincane olusetyenziswa ukuze ubhale igumbi elincane le-Lego lokusebenzisa ukuze ubhale igumbi elincane le-Lego. Ipolymer ingenziwa ngeminyaka engamabili emathathu elilandelayo amonotha, okuyinqubo lamonotha. Lokhu kulandelana nendlela apho amagumbi a-Lego azilindezelana ukwenza into enkulu kunye nokuthi ngenziwayo. Kunezinye izinhlobo zamonotha ezinokusetyenziswa ukupolimerizela ukuze ungenziwe ipolimera elikhona ukusetshenziswa ukuba wenze isibakabhakaba esidingiweyo.
Umnotho wokuqala lokuhlola isibhendisi yilokhu lapho amacume wezithole nezintaka zokugcina zihlabeleka kwezindawo. Sizodinga izinto, kodwa ngalesi sikhathi singafuna ukulandelana ngeemakarabo emagcineni njengoba siyahlola kuphela ukuze sihlale kumakarabo okufanele lokuhlola isibhendisi. Ngokushesha amakarabo akhuphele kwiqhawe elishona elithi petrochemical plant. Emakarabo ahlulekile kwindawo yokusebenza olunye. Bazotheziwe noma bavamele kubantu ababili ukwenzela amonome neepolimari. Ngemuva kokuthi babekho, babhenzele kumafaktori angaphezu kwabo apha asetshentiswa ukwenza izinto eziningi eziphumla kuzo esebenza kuyo.
Inqubo yokwenza ipulasitiki ihilela into esemqoka ebizwa ngokuthi ama-monomer. Zisiza ekwakheni amaketanga amade ama-polymer anika ipulasitiki izakhiwo zayo ezikhethekile njengokuqina nokuqina. Izithasiselo kungenye inketho esinayo (ngaphandle kwama-monomer). Izithasiselo zingamakhemikhali ashintsha izakhiwo zepulasitiki. Ngokwesibonelo, zingase zifake umbala, zilungise ukwakheka kwazo noma zithuthukise ukuqina kwepulasitiki. Ama-antioxidants, anweba ukuphila kwepulasitiki, ama-UV stabilizers, ayivikela elangeni, nama-plasticizers, anika ipulasitiki ubumnene bayo, izibonelo ezimbalwa nje zezithasiselo eziningi. Ngakho-ke, kubaluleke kakhulu ukukhetha izithasiselo eziphephile nezingcono ukuze sivikele umhlaba wethu kangcono futhi siqinisekise impilo yethu enhle.
Kuyona okwesaba, iDola lame liphathelwe amandla engezi kakhulu ngomhla — njengokusho, umthentiselo wemayiphi. Lokhu kulandelwa ukuthi kuninzi amakampani, futhi nethu, abebeqele izinto ezibonakalayo nokulula okanye ukuhlola kwesilondolozi esiqhelekileyo ukusetyenziswa kuhlukele isilondolozi sokuqala. Ukubanzi lokunquma kuhlala ngokuphumeleyo kungaba imayiphi yezombili. Ngaphandle komayiphi oludala, imayiphi yezi zikhona emva kokuba zizifundeki zokuphucukeleza ngokuzenzekelayo, njengamasitshanti wesukhovu okanye usukhovu. Bona bantfu, sebenzisa lezi zintuthuko ziyinga labo? Yonke lo msebenzi wemayiphi wawo. Izinto ezimbili ezincane ezisebenziswayo ezikhethekileyo ezizithathe izindaba zingene kuqalelo loluqululo lwezombili, nezinkomo zasebambo nezihempu, zibebeqele njalo njengamakhompiyutha ekufuneka kuhlala ngokuphumeleyo kuhlukele isilondolozi.
