Lintho tse tala tsa polasetiki ke resin ea maiketsetso, e ntšoang ebe e entsoe ka petroleum, khase ea tlhaho kapa ho phatloha ha mashala.Oli, khase ea tlhaho, joalo-joalo, li senyehile ho ba metsoako ea limolek'hule tse tlase (joalo ka ethylene, propylene, styrene, ethylene, vinyl alcohol, joalo-joalo), 'me metsoako ea limolek'hule tse tlase li entsoe ka polymer ho etsa metsoako ea limolek'hule tse phahameng tlasa maemo a itseng. , ebe li-plasticizers, Lubricant, fillers, joalo-joalo, li ka etsoa ka lisebelisoa tse sa tšoaneng tsa polasetiki.Ka kakaretso, li-resin li etsoa ka granules hore li sebelisoe habonolo.Hangata li bōptjoa ka lisebelisoa tse nang le libopeho tse itseng tlas'a maemo a futhumatsang le khatello.
Lintho tsa 'mele tsa polasetiki.Ho na le mefuta e mengata ea thepa ea 'mele ea polasetiki, tse latelang ke tse fokolang feela tse hlokang ho utloisisoa bakeng sa ho ithuta theknoloji ea toning:
1. Relative density: Relative density ke karo-karolelano ea boima ba sampuli ho boima ba bophahamo bo lekanang ba metsi mochesong o itseng, 'me ke mokhoa oa bohlokoa oa ho khetholla thepa e tala.
2. Sekhahla sa ho monya metsi: Thepa e tala ea polasetiki e entsoe sampole ea boholo bo boletsoeng, e qoelisoa ka metsing a kolobisitsoeng ka mocheso oa (25±2) ℃, le karo-karolelano ea metsi a monngoang ke sampole ho thepa e tala. ka mor'a lihora tse 24.Boholo ba ho monya metsi bo etsa qeto ea hore na thepa e tala ea polasetiki e hloka ho apehoa le bolelele ba nako ea ho baka.
3. Mocheso oa ho bopa: Mocheso oa ho bopa o bolela mocheso o qhibilihang oa thepa e tala ea resin
4. Mocheso oa ho bola: Mocheso oa ho bola o bolela mocheso oo ketane ea macromolecular ea polasetiki e robehang ha e futhumala, hape ke e 'ngoe ea matšoao a ho khetholla mocheso oa polasetiki.Ha mocheso o qhibilihang o feta mocheso oa ho bola, boholo ba lisebelisoa tse tala li tla fetoha mosehla, esita le ho chesoa le ho ba ntšo, 'me matla a sehlahisoa a tla fokotseha haholo.
