| Isitsha sokudla se-PP | Isitsha sokudla se-PS | Isitsha sokudla se-EPS | |
| Isithako esiyinhloko
| I-Polypropylene (PP) | I-Polyethylene (PS) | I-polypropylene enegwebu (I-Polypropylene ene-ejenti yokuvunguza) |
| Ukusebenza kokushisa | Ukumelana nokushisa okuphezulu, kungafakwa kuma-microwave ukuze kufudunyezwe i-PP, sebenzisa izinga lokushisa: -30℃ -140℃ | Ukumelana nokushisa okuphansi, izinga lokushisa lokusebenza le-PS -30℃ -90℃ | Izinga lokushisa lokusebenza le-EPS elimelana nokushisa okuphansi ≤85℃ |
| Izakhiwo zomzimba | Amandla aphezulu, ubulukhuni obuphezulu kanye nokuqina okuphezulu | Amandla aphansi okushayisana, abuthakathaka futhi ayaphuka | Ukuqina okuphansi, ukungangeni kahle kwamanzi |
| Ukuqina kwamakhemikhali
| Ukuqina kwamakhemikhali okuphezulu (ngaphandle kwe-nitric acid egxilile kanye ne-sulfuric acid egxilile), umphumela ophezulu wokubulala amagciwane | Ayikwazi ukulayisha izinto eziyisisekelo eziqinile kanye ne-asidi eqinile
| Ukuzinza okuphansi kwamakhemikhali, kuphendula ngamakhemikhali nama-asidi aqinile, izisekelo eziqinile, ukunambitheka nezinye izinto |
| Umthelela kwezemvelo | Ukubola kungasheshiswa ngokungeza izinto ezibolayo, okulula ukuzisebenzisa kabusha | Kunzima ukulihlisa isithunzi | Kunzima ukulihlisa isithunzi |
Isitsha sokudla se-microwave se-PP simelana namazinga okushisa aphezulu angu-130°C. Leli yibhokisi lepulasitiki kuphela elingafakwa kuhhavini we-microwave futhi lingasetshenziswa kabusha ngemva kokuhlanzwa ngokucophelela. Kubalulekile ukuqaphela ukuthi amanye amabhokisi esidlo sasemini se-microwave, umzimba webhokisi wenziwe nge-No. 05 PP, kodwa isivalo senziwe nge-No. 06 PS (polystyrene), i-PS inokukhanya okuhle, kodwa ayimelani namazinga okushisa aphezulu. Ukuze uphephe, susa isivalo sesitsha ngaphambi kokusifaka ku-microwave.
I-PS iyinto esetshenziselwa ukwenza izitsha zamabhokisi e-noodle asheshayo kanye namabhokisi okudla okusheshayo anegwebu. Ayimelani nokushisa futhi ayibandi, kodwa ayikwazi ukufakwa kuhhavini we-microwave ukugwema ukukhishwa kwamakhemikhali ngenxa yokushisa okukhulu. Futhi ayikwazi ukusetshenziselwa ukuqukatha ama-asidi aqinile (njengejusi lewolintshi), izinto ezinamandla ze-alkaline, ngoba izobola i-polystyrene engalungile emzimbeni womuntu. Ngakho-ke, kufanele uzame ukugwema ukusebenzisa amabhokisi okudla okusheshayo ukupakisha ukudla okushisayo.
Isitsha sokudla se-EPS senziwe nge-Polypropylene ene-blowing agent, futhi asisathandwa ngenxa ye-BPA, okungaba yingozi empilweni yomuntu. Okwamanje asisebenzi kahle kakhulu ekuzinzeni kokushisa komzimba kanye namakhemikhali, kunzima ukuwohloka, futhi sinethonya elibi emvelweni.
