Hauv qhov no, puas yog cov khob polypropylene rov ua dua tshiab?
Polypropylene yog polymer yas uas yog tus tswv cuab ntawm 'polyolefin' (polymers tsim los ntawm alkenes) tsev neeg. Nws yog cov khoom siv tau zoo thiab muaj zog uas muaj ntau yam txiaj ntsig ntawm lub cev, thiab qhov tseem ceeb tshaj plaws nws kuj yog rov ua dua tshiab . Cov PP tam sim no kev lag luam tau kwv yees kom ncav cuag $ 133 nphom los ntawm 2023.
Qhov thib ob, puas yog polypropylene biodegrade? Cov plastics feem ntau siv cov roj av xws li polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), thiab polystyrene (PS) tsis yog biodegradable.
Yog li, Polyethylene puas tuaj yeem siv tau?
HDPE tsis yog biodegradable thiab tau siv sijhawm ntau pua xyoo los rhuav tshem, yog li nws yog qhov tseem ceeb uas cov hnab thiab ntim khoom no yog rov ua dua thiab siv dua. Rov ua dua HDPE muaj ntau yam txiaj ntsig. Piv txwv li, nws raug nqi ntau dua los tsim cov khoom lag luam los ntawm rov ua dua HDPE dua li nws yog los tsim 'nkauj xwb' yas. Rov ua dua lub thoob
