PP chakudya chotengera | PS chotengera chakudya | Chidebe cha chakudya cha EPS | |
Chofunikira chachikulu | Polypropylene (PP) | Polyethylene (PS) | polypropylene thovu (Polypropylene yokhala ndi chowombera) |
Kutentha kwachangu | High kutentha kukana, akhoza microwaved kutentha PP, ntchito kutentha: -30 ℃ -140 ℃ | Low kutentha kukana, PS ntchito kutentha -30 ℃-90 ℃ | Otsika kutentha kukana EPS ntchito kutentha ≤85 ℃ |
Thupi katundu | Mphamvu yapamwamba, kuuma kwakukulu komanso kusungunuka kwakukulu | Mphamvu yocheperako, yofooka komanso yosweka | Low toughness, osauka impermeability |
Kukhazikika kwamankhwala | Mkulu mankhwala bata (kupatula anaikira nitric asidi ndi anaikira sulfuric asidi), mkulu antiseptic kwenikweni | Sizingatheke kuyika asidi amphamvu ndi zida zoyambira zolimba | Kukhazikika kwamankhwala otsika, kumakhudzidwa ndi ma acid amphamvu, zoyambira zolimba, zokometsera ndi zinthu zina |
Kukhudza chilengedwe | Kuwola kumatha kufulumizitsidwa powonjezera zinthu zowonongeka, zosavuta kuzibwezeretsanso | Zovuta kutsitsa | Zovuta kutsitsa |
Chidebe cha chakudya cha PP cha microwave sichimva kutentha kwa 130 ° C.Ili ndi bokosi lokhalo lapulasitiki lomwe limatha kuikidwa mu uvuni wa microwave ndipo litha kugwiritsidwanso ntchito mukatsuka mosamala.Ndikofunika kuzindikira kuti mabokosi ena a microwave nkhomaliro, thupi la bokosi limapangidwa ndi No. 05 PP, koma chivindikirocho chimapangidwa ndi No. khalani otetezeka, chotsani chivindikiro cha chidebecho musanachiike mu microwave.
PS ndi zinthu zomwe zimagwiritsidwa ntchito popanga mbale za mabokosi a noodles pompopompo komanso mabokosi akudya othamanga.Imalimbana ndi kutentha komanso kuzizira, koma siyingayikidwe mu uvuni wa microwave kuti musatulutse mankhwala chifukwa cha kutentha kwambiri.Ndipo sangagwiritsidwe ntchito kukhala ndi ma asidi amphamvu (monga madzi a lalanje), zinthu zamchere zamphamvu, chifukwa zidzawola polystyrene zomwe sizili bwino kwa thupi la munthu.Chifukwa chake, muyenera kuyesetsa kupewa kugwiritsa ntchito mabokosi azakudya mwachangu kuti munyamule zakudya zotentha.
Chidebe cha chakudya cha EPS chimapangidwa ndi Polypropylene yokhala ndi chowombera, ndipo sichidziwikanso chifukwa cha BPA, chomwe chingakhale chovulaza thanzi la munthu.Pakadali pano ili ndi kusachita bwino kwambiri pa Thermal thupi ndi Chemical bata, zovuta kuyipitsa, kukopa koyipa kwa chilengedwe.
