Ingabe iinkomitjhana zetiye zeplastiki ziphephile?

Ingabe iinkomishi zetiye zeplastiki ziphephile?

Ukusetjenziswa okukhulu kweenkomitjhana zetiye zeplastiki ezilahlwako kulethe ubulula obukhulu epilwenamuhla, khulukhulu iinselo ezithatha ngaphandle neminyanya emikhulu. Kodwana, njengombana ukutjheja iindaba zezamaphilo nezebhoduluko kukhuphukile, ukutshwenyeka ngokuphepha kweenkomitjhana zetiye zeplastiki ezilahlwako nakho kutjhejwe. I-atikili le ihlola ukuphepha kwamakomitjhini la ngeendlela ezihlukahlukeneko, okufaka hlangana ukuphepha kwezinto zeplastiki, umthelela wepilo ongaba khona, ukutshwenyeka ngebhoduluko, kanye namathiphu wokuthi ungazisebenzisa njani iinkomitjhana zeplastiki ezilahlwako ngokuphepha. Ihlose ukusiza abafundi bazwisise ngokuzeleko into ejayelekileko yangelanga.

Ukuhlaziywa kwepahla yeenkomishi zetiye zeplastiki ezilahlwako

Iinsetjenziswa ezisetjenziselwa ukwenza iinkomitjhana zetiye zeplastiki ezilahlwako zifaka hlangana i-Polypropylene (PP) kanye ne-Polyethylene Terephthalate (PET). Iinsetjenziswa lezi zaziwa ngokusebenza kwazo okuhle khulu, ukujamelana nokutjhisa, nokungabizi, okwenza bona zilungele ukukhiqizwa ngobunengi.

I-Polypropylene (PP):

1. Ukujamelana nokutjhisa kuvamise ukusuka ku-100°C ukuya ku-120°C, nge-PP esezingeni eliphezulu ekghona ukujamelana namazinga womtjhiso aphezulu.
2. Ayinabuthi, ayinaphunga, begodu inokuzinza okuhle kwamakhemikhali nokujamelana nokutjhayisana.
3. Isetjenziswa kanengi eentjeni ezisetjenziswa ema-microwave, iinqhema zamabhodlela weenselo, nokunye.

I-Polyethylene Terephthalate (PET):

1. Ngokuvamileko isetjenziselwa ukwenza amabhodlela wesiphuzo angatjhiswako kanye namakhonteyina wokupakisha ukudla.
2. Ukujamelana nokutjhisa kusuka ku-70°C ukuya ku-100°C, ngezinto ze-PET eziphathwe ngokukhethekileko ezikghona ukujamelana namazinga womtjhiso aphezulu.
3. Inikela ukukhanya okuhle, ukuzinza kwamakhemikhali okuphezulu, nokujamelana nokugqwala kwe-asidi ne-alkali.

Imithelela yezamaphilo engaba khona yeenkomitjhana zetiye zeplastiki ezilahlwako

Ukukhutjhwa kwamakhemikhali: Lokha iinkomitjhana zetiye zeplastiki nazisetjenziswa eendaweni ezinetjhisa eliphezulu nofana ezine-esidi, zingakhupha amakhemikhali athileko angabanga ubungozi bepilo, afana ne-Bisphenol A (BPA) kanye nama-phthalates. Izinto lezi zingaphazamisa ihlelo lomzimba lomuntu, begodu ukuvezwa isikhathi eside kungabangela imiraro ehlukileko yezamaphilo, okufaka hlangana ukungalingani kwamahomoni kanye namalwelwe wehlelo lokuzala. Kuqakathekile ukukhetha izinto zeplastiki ezifaneleko.

Indlela yokusebenzisa iinkomitjhana zetiye zeplastiki ezilahlwako ngokuphepha

Nanyana kuneentjhijilo ezithile zokuphepha nezebhoduluko ngeenkezo zetiye zeplastiki ezilahlwako, abathengi banganciphisa ubungozi lobu ngokusebenzisa kuhle nezinye iindlela.

Balekela ukusetjenziselwa amazinga womtjhiso aphezulu: Eenkomitjhini zetiye zeplastiki ezijamelana nokutjhisa okuphasi, khulukhulu lezo ezenziwe nge-polystyrene, kuhle ukugwema ukuzisebenzisela iinselo ezitjhisako ukukhandela ukukhutjhwa kwezinto eziyingozi. Kunalokho, khetha iinkomitjhana ezenziwe ngezinto ezijamelana nokutjhisa njenge-Polypropylene (PP).

Khetha imikhiqizo engena-BPA: Lokha nawuthenga iinkomitjhana zetiye ezilahlwako, linga ukukhetha imikhiqizo ebhalwe ngokuthi "ayina-BPA" ukwehlisa ubungozi bepilo obuhlobene ne-Bisphenol A.

Ezinye iindlela ezingalimazi ibhoduluko: Ezinye iinkomitjhana ezilahlwako ezingalimazi ibhoduluko zenziwa ngezinto ezibolako ezifana ne-PLA (Polylactic Acid), ezinomthelela omncani emvelweni.

Umtjhini wokwenza ikopi ye-hydraulic
Umtjhini wokwenza i-GtmSmart Cup wenzelwe ukusebenza ngamashidi we-thermoplastic wezinto ezihlukahlukeneko ezifana ne-PP, PET, PS, PLA, nezinye, ukuqinisekisa bona unokukghona ukuhlangabezana neendingo zakho zokukhiqiza. Ngomtjhini wethu, ungenza iimfesi zeplastiki ezisezingeni eliphezulu ezingasi zihle kwaphela kodwana ezingalimazi ibhoduluko.
