| PP ntim khoom noj | PS khoom noj khoom haus | EPS ntim khoom noj | |
| Cov khoom tseem ceeb
| Polypropylene (PP) | Polyethylene (PS) | Ua npuas ncauj polypropylene (Polypropylene nrog tshuab tshuab) |
| Kev ua haujlwm thermal | Kev kub siab ua haujlwm, tuaj yeem microwaved rau cua sov PP, siv kub: -30 ℃ -140 ℃ | Tsawg kub tsis kam, PS kev khiav hauj lwm kub -30 ℃ -90 ℃ | Tsawg kub tsis kam EPS ua haujlwm kub ≤85 ℃ |
| Lub cev muaj zog | Siab zog, siab hardness thiab siab elasticity | Tsawg cuam tshuam lub zog, tawg thiab tawg | Tsawg toughness, tsis zoo impermeability |
| Tshuaj stability
| Kev ruaj ntseg tshuaj lom neeg (tshwj tsis yog cov concentrated nitric acid thiab concentrated sulfuric acid), cov nyhuv antiseptic siab | Tsis tuaj yeem thauj cov kua qaub thiab cov ntaub ntawv muaj zog
| Tsis tshua muaj tshuaj stability, tshuaj reacts nrog muaj zog acids, muaj zog bases, flavors thiab lwm yam khoom |
| Kev cuam tshuam ib puag ncig | Decomposition tuaj yeem nrawm los ntawm kev ntxiv cov khoom degradable, yooj yim rau rov ua dua | Yooj yim rau degrade | Yooj yim rau degrade |
PP microwave ntim khoom noj yog tiv taus kub ntawm 130 ° C.Qhov no yog lub thawv yas nkaus xwb uas tuaj yeem muab tso rau hauv lub qhov cub microwave thiab tuaj yeem rov qab siv tau tom qab ua tib zoo tu.Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qee lub thawv noj su hauv microwave, lub thawv lub cev yog ua los ntawm No. 05 PP, tab sis lub hau yog ua los ntawm No. 06 PS (polystyrene), PS muaj cov pob tshab zoo, tab sis tsis tiv taus qhov kub thiab txias, muaj kev nyab xeeb, tshem lub hau ntawm lub thawv ua ntej muab tso rau hauv lub microwave.
PS yog cov khoom siv los ua cov tais ntim cov noodle cov thawv thiab cov thawv ntim khoom noj ceev ceev.Nws yog kub-resistant thiab txias-resistant, tab sis tsis tuaj yeem muab tso rau hauv lub qhov cub microwave kom tsis txhob tso cov tshuaj vim yog kub dhau.Thiab tsis tuaj yeem siv kom muaj cov kua qaub uas muaj zog (xws li kua txiv kab ntxwv), muaj zog alkaline tshuaj, vim nws yuav decompose polystyrene uas tsis zoo rau tib neeg lub cev.Yog li ntawd, koj yuav tsum sim tsis txhob siv cov thawv ntim khoom noj ceev kom ntim cov zaub mov kub.
EPS lub thawv khoom noj yog ua los ntawm Polypropylene nrog lub tshuab tshuab, thiab nws tsis nrov dua vim BPA, uas yuav ua rau tib neeg noj qab haus huv.Meanwhile nws muaj kev ua haujlwm tsis zoo ntawm thermal lub cev thiab tshuaj lom neeg ruaj khov, nyuaj rau degrade, cuam tshuam tsis zoo rau ib puag ncig.
