Lintho tse fapaneng tsa polasetiki li etsa qeto ea hore na li sebelisoa joang indastering.Ka tsoelo-pele ea theknoloji, lipatlisiso mabapi le phetoho ea polasetiki ha lia emisa.Litšobotsi tsa mantlha tsa polasetiki ke life?
1. Bongata ba lipolasetiki li boima bo bobebe, li tsitsitse lik’hemik’hale, ’me ha li na mafome;
2. Tšusumetso e ntle ea ho hanyetsa;
3. E na le pepenene e ntle le ho hanyetsa ho apara;
4. Ho kenya letsoho hantle le ho fokotsa mocheso o tlaase;
5. Sebopeho se akaretsang le colorability li ntle, 'me litšenyehelo tsa ho sebetsa li tlaase;
6. Lipolasetiki tse ngata li na le mocheso o fokolang oa mocheso, lebelo le phahameng la ho atolosa mocheso le ho chesa habonolo;
7. Mafutsana dimensional botsitso le bonolo ho deform;
8. Li-plastiki tse ngata li na le mocheso o fokolang oa ho hanyetsa mocheso, li fetoha brittle mocheso o tlaase le ho tsofala habonolo;
9. Li-plastiki tse ling li qhibiliha habonolo ka har'a lihlapolli.
10. Plastiki e ka aroloa likarolo tse peli: thermosetting le thermoplastic.Ea pele e ke ke ea etsoa bocha hore e sebelisoe, 'me ea morao-rao e ka hlahisoa hape.Thermoplasticity e na le bolelele bo boholo ba 'mele, ka kakaretso ke 50% ho isa ho 500%.Matla ha a fapane ka ho feletseng ka li-elongations tse fapaneng.
Ha e le hantle ho na le mefuta e 'meli ea mehaho ea limolek'hule tsa polasetiki: ea pele ke mohaho o nang le mela,' me motsoako oa polymer o nang le mohaho ona o bitsoa motsoako oa polymer linear;ea bobeli ke sebopeho sa 'mele,' me motsoako oa polymer o nang le mohaho ona o bitsoa motsoako.Ke motsoako oa polymer ka bongata.Li-polymers tse ling li na le liketane tse nang le makala, tse bitsoang li-polymers tsa branched, tseo e leng tsa sebopeho sa mela.Le hoja li-polymers tse ling li na le li-cross-link pakeng tsa limolek'hule, empa li-cross-link tse fokolang, tse bitsoang sebopeho sa marang-rang, ke tsa sebopeho sa 'mele.
Mehaho e 'meli e fapaneng, e bonts'ang thepa e 'meli e fapaneng.Sebopeho sa linear, ho futhumatsa ho ka qhibiliha, ho fokotseha ho thata le ho brittleness.Sebopeho sa 'mele se na le boima bo boholo le bo brittleness.Plastiki e na le meaho e 'meli ea li-polymers, thermoplastics e entsoeng ka li-polymer tse melang, le lipolasetiki tsa thermosetting tse entsoeng ka li-polymer tse ngata.
