Pepa rePP rinodzivisa moto ipepa repurasitiki rakagadzirwa nePP resin, rine zvimwe zvinhu zvinoshanda zvinowedzerwa kuburikidza nekubvisa, kuyera, kutonhora, kucheka nezvimwe. Pepa rePP rinodzivisa moto ipurasitiki ine semi-crystalline. Rakaoma kupfuura PE uye rine nzvimbo yakakwira yekunyunguduka. Nekuti tembiricha yePP ye homopolymer inopfava kupfuura 0C, zvinhu zvakawanda zvePP zvekutengeserana ndezve random copolymers dzine 1-4% ethylene content kana block copolymers dzine ethylene content yakakwira. Zvinhu zveCopolymer PP zvine tembiricha yakaderera yekupisa (100°C), kujeka kwakaderera, kupenya kwakaderera, uye kuomarara kwakaderera, asi zvine simba rakasimba rekubata. Saka, ungaziva sei mhando yepepa rePP rinodzivisa moto?
1. Tarisa kupenya kwayo pamusoro. Kupenya kwacho kusina kunaka ipurasitiki yakadzokororwa.
2. Tarisa kusimba kwayo. Pepa rePP rinodzivisa moto rakachena rine kusimba kwakanaka uye rinogona kukotama zvishoma.
3. Tarisa nzvimbo yekucheka. Mushure mekucheka mapurasitiki akadzokororwa, pachava nemarara akasiyana-siyana ane mavara akasiyana.
4. Tarisa huwandu hwayo. Huwandu hwePP polypropylene i0.92~0.93. Zvinhu zvese zvinoyangarara pamusoro pemvura ipolypropylene.
5. Pepa rePP rinodzivisa moto rinodziiswa uye rinosungirirwa. Utsi hunobuda kana uchibatanidza mapurasitiki akadzokororwa.
6. Kutumira chiedza, mapurasitiki akadzokororwa haana chiedza chakawanda.
7. Kusimba kwepurasitiki, kushandiswazve kwayo kwakaipawo zvikuru.
8. PP sheet density inodzivirira moto, ikande mumvura kuti uone kana ichiyangarara pamusoro pemvura, mvura zhinji yakadzokororwa inonyura pasi.
