Ungayikhetha Kanjani Inkomishi Yepulasitiki Elahlwayo?

Izinkomishi zepulasitiki ezilahlwayo zihlukaniswa kakhulu zibe izinhlobo ezintathu ngezinto ezingavuthiwe

1. PET indebe

I-PET, ipulasitiki engu-1, i-polyethylene terephthalate, evame ukusetshenziswa emabhodleleni amanzi amaminerali, amabhodlela eziphuzo ezihlukahlukene nezinkomishi zesiphuzo esibandayo. Kulula ukuguqulwa ku-70 ℃, futhi izinto eziyingozi emzimbeni womuntu ziyancibilika. Ungashisi elangeni, futhi ungafaki utshwala, amafutha nezinye izinto.

2. Inkomishi ye-PS

I-PS, No. 6 ipulasitiki, i-polystyrene, ingakwazi ukumelana nokushisa okungaba ngu-60-70 degrees. Ngokuvamile sisetshenziswa njengesiphuzo esibandayo. Iziphuzo ezishisayo zizokhipha ubuthi futhi zibe nokuthungwa okuphukayo.

3. Inkomishi yePP

PP, No. 5 plastic, polypropylene. Uma kuqhathaniswa ne-PET ne-PS, inkomishi ye-PP iyinto ethandwa kakhulu yesiqukathi sepulasitiki, esingamelana nezinga lokushisa elingu-130 ° C futhi iwukuphela kwento yesitsha sepulasitiki esingafakwa kuhhavini wemicrowave.

Lapho ukhetha izinkomishi zamanzi alahlwayo zepulasitiki, khomba ilogo engezansi. Inkomishi engu-5 ye-PP ingasetshenziselwa kokubili iziphuzo ezibandayo nezishisayo, futhi No. 1 PET kanye No. 6 PS zingasetshenziselwa iziphuzo ezibandayo kuphela, khumbula.

Kungakhathaliseki ukuthi inkomishi yepulasitiki elahlwayo noma inkomishi yephepha, kungcono ukungaphinde uyisebenzise. Iziphuzo ezibandayo nezishisayo kufanele zihlukaniswe. Amanye amabhizinisi angekho emthethweni asebenzisa amaphepha agaywe kabusha namapulasitiki agaywe kabusha ukuze kuzuze abanye. Kunzima ukubala konke ukungcola, kodwa futhi iqukethe izinsimbi ezihlukahlukene ezinzima noma ezinye izinto eziyingozi. Ngakho-ke, kungcono ukukhetha imikhiqizo evela kubakhiqizi abajwayelekile. Lokho abathengi abajwayelekile abangakuqondi ukuthi phakathi kwezinkomishi zepulasitiki ezilahlwayo nezinkomishi zephepha, izinto zepulasitiki ziphakeme kunephepha. Kungacatshangelwa ezicini ezimbili: 1. Inqubo yokukhiqiza izinkomishi zepulasitiki ezilahlwayo ilula, futhi ukuhlanzeka kulula ukulawula. Izinkomishi zamaphepha ziyinkimbinkimbi, zinezixhumanisi eziningi zokukhiqiza, futhi ukukhucululwa kwendle akulula ukulawula. 2. Inkomishi yepulasitiki elahlwayo efanelekayo, engenabuthi futhi ayingcolisi. Ngisho nezinkomishi zephepha ezifanelekayo kulula ukuhlukanisa izindaba zangaphandle. Ngaphezu kwalokho, izinto ezisetshenziselwa izinkomishi zephepha zivela ezihlahleni, ezidla imithombo yehlathi ngokweqile futhi zibe nomthelela omkhulu emvelweni.
