Imikhiqizo yepulasitikisebeyingxenye ebalulekile yokuphila kwethu kwansuku zonke.Amapulastiki angena cishe kuzo zonke izici zomhlaba wanamuhla, kusukelai-kitchenware to electronics, imishini yezokwelaphaezintweni zokwakha.Kodwa-ke, ukukhathazeka okukhulayo mayelana nomthelela wemvelo wepulasitiki kuye kwabangela ukuhlolwa kwezinye izinto ezifana nama-silicones.
I-Silicone iyimpahla yokwenziwa etholakala ku-silicon, into eyenzeka ngokwemvelo etholakala esihlabathini ne-quartz.Inezimfanelo eziningi ezifiselekayo, ezifana nokumelana nokushisa okuphezulu, ukuguquguquka nokuqina, okwenza kube indawo enhle kakhulu yamapulasitiki ezinhlobonhlobo zezicelo.Ukusetshenziswa kwayo ku-kitchenware, i-electronics, imishini yezokwelapha kanye nezinto zokwakha kuye kwanda kancane kancane.
Enye yezinto ezibalulekileimithelela yezemveloimikhiqizo yepulasitiki ukungcola kanye nemfucuza.Ipulasitiki ithatha amakhulu eminyaka ukubola, okwenza imfucuza inqwabelane ezindaweni zokulahla imfucumfucu futhi ingcolise izilwandle zethu kanye nemisele yamanzi.Ngakolunye uhlangothi, imikhiqizo ye-silicone inomthelela ophansi emvelweni ngoba ihlala isikhathi eside futhi ingasetshenziswa kabusha.Ngaphezu kwalokho, ama-silicone anobungane bokulahla imfucumfucu futhi abola abe izinto ezingenabungozi njenge-silica ne-carbon dioxide.
Kukhona nokukhathazeka ngokuthi amakhemikhali asezintweni zepulasitiki angangena ekudleni naseziphuzweni.I-Phthalates ne-bisphenol A (BPA) yizithasiselo ezivame ukusetshenziswa ekukhiqizeni ipulasitiki futhi zixhunywe nokukhathazeka kwezempilo.Ngokuphambene, imikhiqizo ye-silicone ibhekwa njengezinga lokudla futhi ayikhiphi amakhemikhali ayingozi lapho ithinta ukudla noma iziphuzo.Lokhu kwenza i-silicone ibe inketho ephephile ku-cookware, iqinisekisa ukuthi azikho izinto ezingaba ubuthi ezingcolisa ukudla kwethu.
Ku-electronics, umthelela wepulasitiki wemvelo ubonakala enkingeni ekhulayo ye-e-waste.Imishini kagesi iqukethe izingxenye zepulasitiki okunzima ukuzigaya kabusha futhi ngokuvamile zigcina sezisendaweni yokulahla imfucumfucu noma ezindaweni zokushisisa.I-Silicone inikeza isisombululo esimeme kakhudlwana ngenxa yokuqina kwayo okuphezulu kanye nokumelana namazinga okushisa aphezulu.Ingakwazi ukumelana nezimo ezinzima futhi kulula ukuyigaya kabusha kunepulasitiki, kunciphisa umthwalo wemvelo ohambisana ne-e-waste.
Imishini yezokwelapha ingenye indawo eya ngokuya yamukela i-silicone.Izingxenye zepulasitiki kumishini yezokwelapha zingadala izingozi ezifana nokungezwani komzimba nokuvuza kwezinto eziyingozi emzimbeni.I-silicone, ngakolunye uhlangothi, i-biocompatible, ayinabo ubuthi futhi i-hypoallergenic, okwenza kube yisinqumo sokuqala sezinhlelo zokusebenza zezokwelapha.Ikhono layo lokumelana nokuvala inzalo okuphindaphindiwe futhi liyanezela ekuthandeni kwayo.
Uma kukhulunywa ngezinto zokwakha, amapulasitiki asetshenziswa kakhulu ngenxa yokuguquguquka kwawo, ukufinyeleleka kwawo kanye nesisindo esilula.Kodwa-ke, izinto zokwakha zepulasitiki zikhiqiza imfucuza enkulu ngesikhathi sokukhiqiza nokulahlwa.I-Silicone inikeza enye indlela evumelana nemvelo njengoba igaywa kabusha, ihlala isikhathi eside futhi iyonga amandla.Izinkampani ziya ngokuya zihlola ukusetshenziswa kwezinto ze-silicone ekwakheni ukuze kuncishiswe umthelela wemvelo ohambisana namapulasitiki.
Sengiphetha, kunomehluko omkhulu emthelela wemvelo wei-silicone nemikhiqizo yepulasitiki.Nakuba imikhiqizo yepulasitiki ibangela ukungcola, ukunqwabelana kwemfucuza kanye nezingozi ezingase zibe yingozi empilweni, ama-silicone anikeza isisombululo esimeme kakhudlwana.Ukuqina kwayo, ukusebenziseka kabusha kanye nemvelo engenabo ubuthi kuyenza ibe indawo ekhethwayo ezimbonini ezihlukahlukene ezifana ne-kitchenware, electronics, imishini yezokwelapha kanye nezokwakha.Njengoba umhlaba ufuna ukunciphisa imiphumela emibi yepulasitiki, ukwamukelwa kwemikhiqizo ye-silicone kungadlala indima ebalulekile ekwakheni ikusasa eliluhlaza.
