Leqephe la PP le thibelang malakabe ke leqephe la polasetiki le entsoeng ka resin ea PP, le nang le lintho tse fapaneng tse sebetsang tse eketsoang ka ho ntša, ho lokisa lik'halori, ho pholisa, ho seha le lits'ebetso tse ling. Leqephe la PP le thibelang malakabe ke thepa e semi-crystalline. Le thata ho feta PE 'me le na le ntlha e phahameng ea ho qhibiliha. Hobane mocheso oa PP oa homopolymer o fokola haholo ka holimo ho 0C, thepa e mengata ea khoebo ea PP ke li-copolymer tse sa reroang tse nang le 1-4% ea ethylene kapa li-block copolymer tse nang le ethylene e phahameng. Lisebelisoa tsa PP tsa Copolymer li na le mocheso o tlase oa ho sotha mocheso (100°C), ponaletso e tlase, khanya e tlase, le ho tiea ho tlase, empa li na le matla a matla a tšusumetso. Joale, u ka khetholla boleng ba leqephe la PP le thibelang malakabe joang?
1. Hlahloba ho benya ha bokaholimo ba eona. Ho benya ho fokolang ke polasetiki e sebelisitsoeng hape.
2. Hlokomela ho tiea ha eona. Leqephe la PP le hloekileng le thibelang malakabe la thepa e tala le na le ho tiea ho hoholo 'me le ka kobeha hanyane.
3. Hlahloba bokaholimo ba ho seha. Kamora ho seha polasetiki e sebedisitsweng hape, ho tla ba le mefuta e fapaneng ya ditshila ka mebala e fapaneng.
4. Hlahloba boima ba eona. Boima ba polypropylene ea PP ke 0.92 ~ 0.93. Lintho tsohle tse phaphametseng holim'a metsi ke polypropylene.
5. Leqephe la PP le thibelang malakabe le futhumatsoa le ho tjhesetswa. Mosi o tswa ha ho tjhesetswa polasetiki e sebedisitsweng hape.
6. Phetiso e bobebe, polasetiki e sebedisitsweng hape e na le phetiso e fokolang ya lesedi.
7. Ho tiea, polasetiki e sebelisitsoeng hape le eona e mpe haholo.
8. Botenya ba pampiri ea PP e thibelang malakabe, e lahlele ka metsing ho bona hore na e phaphametse holim'a metsi, boholo ba metsi a sebelisitsoeng hape a teba ho ea tlaase.
