Ukuhlola ukuhambisana kwezinto
Umtjhini wokuThuthukisa iKopi yePlastiki
Isingeniso:
Nakuziwa ekwenzeni iinkomitjhana zeplastiki, imitjhini yokwenza iinkomitjhana zeplastiki zidlala indima eqakathekileko ekuguquleni izinto ezisetjenziswako zibe mikhiqizo eqediweko. Enye into eqakathekileko ekufuze uyicabangisise lokha nawuthenga umtjhini onjalo kukuvumelana kwawo. Esihlokweni lesi, sizokuhlolisisa izinto ezihambisanako ze- umtjhini wokwenza ikopi yeplastiki, ukutjheja izinto ezisetjenziswa khulu ezifaka hlangana i-PS, i-PET, i-HIPS, i-PP, kanye ne-PLA.
PS (Polystyrene):I-polystyrene yinto edumileko esetjenziselwa ukwenza iinkomitjhana zeplastiki ngebanga lokukhanya kwayo, ukulula, nokungabizi. Umtjhini wokwenza ikopi yeplastiki evumelana ne-PS ungakghona ukubumba begodu ubumbe izinto lezi zibe ziinkomitjhana ezihlukahlukeneko.
I-PET (Polyethylene Terephthalate):
I-PET yinto ehlukileko eyaziwa ngokukhanya kwayo, ukuqina, nokujamelana nokutjhayisana. Ivamise ukusetjenziswa ekukhiqizeni iinkomitjhana zeplastiki ezikhanyako, ngombana inikela ukubonakala okuhle begodu ikhulisa ubuhle bomkhiqizo wokugcina. Khangela umtjhini wokwenza iinkomitjhana zeplastiki ikghona ukusebenza nge-PET ukwenza iinkomitjhana ezisezingeni eliphezulu.
I-HIPS (High Impact Polystyrene):
I-HIPS yinto ehlala isikhathi eside nengathintekiko esetjenziswa khulu embonini yokupakisha ukudla. Inikela ngokuqina okuhle nokuzinza kwemilinganiso, okwenza bona ilungele ukukhiqiza iinkomitjhana zeplastiki eziqinileko. Imitjhini yokwenza iinkomitjhana zeplastiki ekhambisana ne-HIPS ingabumba kuhle into le, ukuqinisekisa bona iinkomitjhini zikghona ukujamelana nobujamo obubudisi bokusetjenziswa.
PP (Polypropylene):
I-polypropylene yinto ehlukileko eyaziwa ngokujamelana namakhemikhali nokubekezelela amazinga womtjhiso aphezulu. Ukwenza iinkomitjhana zeplastiki umtjhini owenzelwe ukuphatha i-PP ungakhiqiza iinkomitjhana ezilula, kodwana eziqinileko nezingatjhiswako. Iinkopi lezi zivame ukusetjenziselwa kokubili iinselo ezitjhisako nezibandako.
I-PLA (Polylactic Acid):
I-PLA yinto esekelwe ekuphileni, evuselelekako evela emithonjeni yeentjalo ezifana nesitashi sommbila nofana umoba. Iya ngokuya ithandwa njengenye indlela engalimazi ibhoduluko yokwenza iinkomitjhana zeplastiki. Umtjhini wokwenza iinkomitjhana zeplastiki ekhambisana ne-PLA ingakghona ukusebenza kuhle izinto ezibolako, okurholela ekutheni kube neenkomitjhana ezingaba mquba ezifaka isandla ekwehliseni umthelela webhoduluko.
Isiphetho:
Lokha nawucabanga ngokuthenga umtjhini wokwenza ikopi yeplastiki, ukuzwisisa ukuhambisana kwayo kwezinto kuqakathekile. Imitjhini ekghona ukusebenza ngezinto ezihlukahlukeneko, okufakahlangana i-PS, i-PET, i-HIPS, i-PP, kanye ne-PLA, inikela ukutjhuguluka okukhulu nokuguquguquka ekukhiqizeni ikopi. Noma ngabe ufuna ukukhanya, ukuqina, ukujamelana nokutjhisa, nofana ukukhetha okunobungani nemvelo, qiniseka bona umtjhini owukhethako uhambisana neemfuneko zezinto ozifunako. Ngokukhetha umtjhini ofaneleko, ungazuza ukukhiqizwa okusebenzako nokuthembekileko kweenkopi zeplastiki ezisezingeni eliphezulu, ezihlangabezana neendingo zabathengi ezihlukahlukeneko ngesikhathi zihlangabezana namazinga webubulo.
