Nakong ea ho etsa polasetiki ea lisebelisoa tse tala tsa polasetiki, maemo a le mong kapa a mangata a latelang a atisa ho etsahala, joalo ka rheology ea lipolymers le liphetoho tsa thepa ea 'mele le ea lik'hemik'hale, tseo hangata li khetholloang ka thepa e latelang:
1. Fluidity: The fluidity ea thermoplastics ka kakaretso e ka khethoa ho tloha letoto la li-indices tse kang boima ba molek'hule, melt index, Archimedes spiral flow length, viscosity e bonahalang le karolelano ea phallo (bolelele ba ts'ebetso / botenya ba lebota la polasetiki).sekaseka.
2. Crystallinity: Ntho e bitsoang "crystallization phenomenon" e bua ka ketsahalo ea hore limolek'hule tsa polasetiki li fetoha ho tloha ho tsamaea ka bolokolohi 'me li senyeha ka ho feletseng ho limolek'hule li emisa ho tsamaea ka bolokolohi' me li hlophisitsoe ka mokhoa o tsitsitseng hanyenyane ho etsa mohlala oa pontšo ea limolek'hule ho tloha ho qhibilihisitsoeng. boemo ho ya ho condensation.
3. Ho utloisisa mocheso: Ho utloisisa mocheso ho bolela hore lipolasetiki tse ling li khona ho mamella mocheso.Ha nako ea ho futhumatsa e le nako e telele mocheso o phahameng kapa phello ea ho kuta e le khōlō, mocheso oa thepa oa eketseha 'me o atisa ho fetoha le ho senyeha.Ha lipolasetiki tse sa utloeng mocheso li senyehile, ho hlahisoa lihlahisoa tse kang monomers, likhase le lintho tse tiileng.Haholo-holo, likhase tse ling tse bolileng lia halefisa, li senya kapa li chefo 'meleng oa motho, lisebelisoa le hlobo.
4. Hydrolysis e bonolo: Esita le haeba li-plastiki tse ling li na le metsi a fokolang feela, li tla bola tlas'a mocheso o phahameng, khatello e phahameng, 'me thepa ena e bitsoa bonolo hydrolysis.Lipolasetiki tsena (tse kang polycarbonate) li tlameha ho futhumatsoa le ho omisoa
5. Khatello ea maikutlo: Li-plastiki tse ling li na le bothata ba ho imeloa kelellong, 'me li na le khatello ea kelello ea ka hare nakong ea ho bōptjoa, e leng brittle le e bonolo ho phunyeha, kapa likarolo tsa polasetiki li phunyeha tlas'a ketso ea matla a ka ntle kapa solvent.Ketsahalo ena e bitsoa khatello ea maikutlo.
6. Qhibiliha fracture: Polima e qhibilihang ka sekhahla se itseng sa phallo e feta ka lesoba la nozzle mocheso o sa fetoheng.Ha sekhahla sa phallo se feta boleng bo itseng, mapetsong a totobetseng a pota-potileng a hlaha holim'a metsi a qhibilihang, a bitsoang fracture ea qhibiliha.Ha ho khethoa sekhahla sa phallo ea ho qhibiliha Ha ho etsoa thepa e tala ea polasetiki ea boleng bo holimo, li-nozzles, limathi le likou tsa phepelo li lokela ho holisoa ho fokotsa lebelo la ente le khatello, le ho eketsa mocheso oa thepa.
