| Chinhu chikuru chinoshandiswa
| Polypropylene (PP) | Polyethylene (PS) | Polypropylene ine furo (Polypropylene ine mushonga wekuputira) |
| Kushanda kwekupisa | Kudzivirira kupisa kwakanyanya, kunogona kuiswa mu microwave kuti kupise PP, tembiricha yekushandisa: -30℃ -140℃ | Kudzivirira kupisa kwakaderera, tembiricha yekushanda yePS -30℃ -90℃ | Kupisa kushoma EPS tembiricha yekushanda ≤85℃ |
| Zvimiro zvemuviri | Simba guru, kuomarara kwakanyanya uye kusimba kwakanyanya | Simba shoma rekukanda, rinopfava uye rinotyoka | Kusimba kwakaderera, kusakwana kwemvura |
| Kugadzikana kwemakemikari
| Kugadzikana kwakanyanya kwemakemikari (kunze kwe nitric acid yakakangwa uye sulfuric acid yakakangwa), mhedzisiro yakakura yekurwisa utachiona | Haikwanise kurodha zvinhu zvine acid yakasimba uye zvinhu zvine base yakasimba
| Kugadzikana kwemakemikari kwakaderera, kunosangana nemakemikari nemaacid akasimba, mabhesi akasimba, manakiro nezvimwe zvinhu |
| Kukanganisa kwezvakatipoteredza | Kuora kunogona kukurumidziswa nekuwedzera zvinhu zvinoora, zviri nyore kudzokorodza | Zvakaoma kuderedza | Zvakaoma kuderedza |
Chirongo chePP che microwave chinodzivirira kupisa kwakanyanya kwe130°C. Iri ndiro bhokisi repurasitiki chete rinogona kuiswa muovheni ye microwave uye rinogona kushandiswazve mushure mekucheneswa nekungwarira. Zvakakosha kuziva kuti mamwe mabhokisi ekudya kwemasikati e microwave, muviri webhokisi wakagadzirwa nenhamba 05 PP, asi chivharo chakagadzirwa nenhamba 06 PS (polystyrene), PS ine kujeka kwakanaka, asi haidziviri kupisa kwakanyanya. Kuti zvive zvakachengeteka, bvisa chivharo chemudziyo usati waisa mu microwave.
PS chinhu chinoshandiswa kugadzira ndiro dzemabhokisi enoodles anokurumidza uye mabhokisi eforo anopupuma. Haidziviriri kupisa uye haitonhori, asi haigone kuiswa muovheni ye microwave kudzivirira kuburitswa kwemakemikari nekuda kwekupisa kwakanyanya. Uye haigone kushandiswa kuva nemaacids akasimba (senge muto weorenji), zvinhu zvine alkaline yakasimba, nekuti inoora polystyrene iyo isina kunaka kumuviri wemunhu. Saka, unofanira kuedza kudzivirira kushandisa mabhokisi eforo anokurumidza kutakura chikafu chinopisa.
Chirongo chechikafu cheEPS chakagadzirwa nePolypropylene chine mushonga wekuputira, uye hachichanyanyi kufarirwa nekuda kweBPA, izvo zvingakuvadza hutano hwevanhu. Panguva iyi hachina simba rakawanda pakupisa kwemuviri nemakemikari, hachina simba rekuparadza, uye hachina simba rakaipa kunharaunda.
