Isingeniso
I-Polystyrene (PS) ingase ingabi yigama olizwa nsuku zonke, kodwa ukuba khona kwayo ezimpilweni zethu zansuku zonke akunakuphikwa. Njenge-polymer yokwenziwa, i-PS isingene kwinqwaba yezinhlelo zokusebenza, kusukela enkomishini yekhofi okungenzeka ukuthi uyibambe njengamanje kuya ephaketheni elivikele ukuthenga kwakho kwakamuva ku-inthanethi. Kulesi sihloko, sizodabula umhlaba we-PS, sihlola izakhiwo zayo, ukusetshenziswa kwayo okuhlukahlukene, kanye nendima yayo eguqukayo ekulandiseni okusimeme.
Izinhlobo Nezakhiwo zePolystyrene
I-Polystyrene, empeleni, ingaphezu nje kwepulasitiki. Kuyinto enezinhlobonhlobo zezakhiwo ezenza intandokazi ezimbonini ezihlukahlukene. Ake sihlukanise izinhlobo zayo eziyinhloko nezici zazo ezihlukile:
Inhloso Ejwayelekile I-Polystyrene (GPPS)
Izakhiwo Ezibonakalayo:
- Ukungafihli: I-GPPS icace bha, iyenza ilungele izinhlelo zokusebenza lapho ukukhanga okubonakalayo nokucaca kubaluleke kakhulu.
- Ukuqina: Kuyinto eqinile, nakuba ingaba brittle, okusho ukuthi ingaphuka ngaphansi komthelela omkhulu.
- -Lulaphele: Ukuminyana kwayo okuphansi kwenza kube intandokazi emikhiqizweni lapho isisindo siyinkinga.
Izakhiwo Zamakhemikhali:
- Ukuncibilika: I-GPPS ayincibiliki emanzini kodwa ingancibilika kwezinye izinyibilikisi zemvelo.
- Ukuzinza Okushisayo: Ingakwazi ukumelana namazinga okushisa aphakathi nendawo kodwa inephuzu eliphansi lokuncibilika, cishe elingu-240°C (464°F).
I-High Impact Polystyrene (HIPS)
Izakhiwo Ezibonakalayo:
- Ukungaboni kahle: Ngokungafani ne-GPPS, i-HIPS imvamisa i-opaque noma i-translucent.
- Ukuqina: Njengoba igama liphakamisa, i-HIPS inokumelana nomthelela ophezulu, okuyenza ibe brittle kune-GPPS.
- Ukuvumelana nezimo: Inikeza ibhalansi phakathi kokuqina nokuvumelana nezimo, okuvumela izinhlelo zokusebenza ezihlukahlukene.
Izakhiwo Zamakhemikhali:
- Ukuncibilika: Ngokufanayo ne-GPPS, i-HIPS ayincibiliki emanzini kodwa ingancibilika kuzincibilikisi ezithile zemvelo.
- Ukuzinza Okushisayo: I-HIPS ingakwazi ukumelana namazinga okushisa aphezulu kune-GPPS, nendawo yokuncibilika ngaphezu kwe-GPPS.
Ezingeni lamangqamuzana, i-Polystyrene iyi-polymer ye-vinyl. Ngokwesakhiwo, iyiketango elide le-hydrocarbon, nayo yonke enye ikhabhoni exhunywe eqenjini le-phenyl (indandatho yamakhabhoni ayi-6). Lesi sakhiwo sinomthelela ekuqineni kwayo nokumelana nokushisa.
Izicelo Ezihlukahlukene ze-PS
Ukuvumelana nezimo kwe-PS kubonakala ezinhlobonhlobo zezinhlelo zokusebenza:
- Ukupakisha: Cabanga ngokupakishwa kwegwebu, iziqukathi zokudla, nalezo zinkomishi ezilahlwayo eziza nezinto ozithathayo.
- Ukwakha: I-PS ithola indlela yayo ezintweni zokufakelwa kanye namabhodi amagwebu, iqinisekisa ukuthi amakhaya ethu ahlala ewonga amandla.
- Izimpahla Zabathengi: Lawo ma-CD case aqoqa uthuli eshalofini lakho? PS. Amathoyizi izingane zakho ezidlala ngawo ngisho nezinto zokusika ezilahlwayo zesidlo sayizolo ebusuku? Konke ku-PS.
Umthelela Wezemvelo Nokusimama
Ukuhlukahluka kwe-PS kuza nokukhathazeka kwemvelo. I-non-biodegradability yayo kanye nesikhathi eside sokubola kuphakamise ama-alamu. Nokho, indaba iyashintsha:
- Imizamo Yokugaywa kabusha: Ukuqanjwa kabusha ekugayweni kabusha kwe-PS kwenza kube nokwenzeka ukuphinda kusetshenziswe lesi sisetshenziswa, kunciphisa indawo yayo yemvelo.
- Ezinye Izindlela Ezingaboli: Ucwaningo luyaqhubeka lokuthuthukisa izinto ezisimeme ze-PS ezibola ngokushesha futhi zishiye umthelela omncane kwezemvelo.
Ubufakazi Babasebenzisi kanye Nempendulo
Ukuzwa kulabo abasebenzisa imikhiqizo ye-PS nsuku zonke kunikeza umbono olinganiselayo:
“Ngiyakuthanda ukunethezeka kokupakishwa kwe-PS, kodwa ngikhathazekile ngomthelela wayo kwezemvelo.” – UJane D.
“Njengomakhi, ukufakwa kwe-PS kube yisiguquli segeyimu. Isebenza kahle futhi kulula ukuyifaka.” – UMike L.
Amathiphu Okusebenzisa I-PS Ngokunesibopho
Kulabo bethu abasebenzisa imikhiqizo ye-PS, nanka amathiphu okuqinisekisa ukuthi senza ingxenye yethu:
- Recycle: Hlala ubheka izimpawu zokugaywa kabusha emikhiqizweni ye-PS.
- Yehlisa Imfucuza: Khetha ezinye izindlela ezingasetshenziswa kabusha uma kungenzeka.
- Ukulahlwa Okufanelekile: Qinisekisa ukuthi imikhiqizo ye-PS ilahlwa ezindaweni ezifanele.
Ukubheka Phambili: Ikusasa le-PS
Umhlaba we-PS uhlala uvela. Ngokucwaninga okuqhubekayo ezintweni ezisimeme kanye nezinhlelo zokusebenza ezintsha ezivelayo, indaba ye-PS isekude ukuphela. Kungakhathaliseki ukuthi izinto ezintsha ku-PS engaboli noma ukusetshenziswa okusha kwezobuchwepheshe, ikusasa libukeka lithembisa.
Isiphetho
I-Polystyrene, nenqwaba yezicelo nezakhiwo zayo, iwubufakazi bezimangaliso zesayensi yesimanje. Njengoba sizulazula ngezinzuzo nezinselele zayo, kubalulekile ukuhlala unolwazi futhi wenze izinqumo ezinengqondo. Sikumema ukuthi wabelane ngemicabango yakho nolwazi lwakho ne-PS kumazwana angezansi.
