Thepa e tsitsitseng ea lipeipi tsa phepelo ea metsi tsa HDPE

Peipi ea metsi ea HDPE e hokae?

Ka lebaka la melemo ea eona e ikhethang,Pipe ea phepelo ea metsi ea HDPEho pharaletseng sebelisoa ka boenjiniere kaho phepelo phala ea metsi, patoa drainage phala, kaho boenjiniere bohareng futhumatsang, phaephe ea khase, tjheseletsa le thepa ea puisano tlhokomelo e sa keneleng metsi, liphaephe tsa boemo ba indasteri, lipeipi tsa temo le liphoofolo tse ruuoang, joalo-joalo E sebelisoa haholo phepelong ea matla, tlhaho. nosetso ea khase le temo litoropong tse kholo.Thepa e ntle haholo e etsa hore sehlahisoa se sebelisoe haholo.Thepa e tsitsitseng ea peipi ea phepelo ea metsi ea PE e tla hlahisoa ka botlalo ka tlase.

Lits'ebetsong tsa lipeipi tsa phepelo ea metsi tsa HDPE, lisebelisoa tsa polymer li na le thepa ea 'mele e hlokahalang.Thepa ea 'mele ea li-polymers tse ngata e phahametse thepa e tsitsitseng ea lisebelisoa tse ling tsa HDPE.Bareki ba bangata ba lumela hore ha re sebelisa lisebelisoa tsa HDPE e le liphaephe tsa phepelo ea metsi, ha re tsotelle thepa e tsitsitseng e le index ea ts'ebetso, empa ha re sebelisa lisebelisoa tse tala, re hloka thepa ea 'mele ea thepa ea polymer.

Ka kakaretso, ho na le lifilimi tse fokotsang mocheso le lifilimi tse honyehang, tse hlokang lisebelisoa tse phahameng tsa lisebelisoa tse tala.Ha e le hantle, lihlahisoa tse khethehileng tsa lisebelisoa tsa HDPE hangata li na le thepa e tsitsitseng e ka bang 200%.Joalo ka ts'ebeliso ea lisebelisoa tsa HDPE, lipalo-palo tsena li nepahetse 'me thepa e tsitsitseng e ntle haholo.Ka lebaka la ho otlolla ho feta tekano, tšepe ea phepelo ea metsi ea HDPE ha e na pelaelo.

HDPE e bapala karolo efe molemong oa ho tiea ha lipeipi tsa metsi?

Ha li-polymer li sebelisoa e le lisebelisoa, bareki ba bangata ha ba thahaselle thepa e hlokahalang ea mochini.Lits'ebetsong tse ngata tsa li-polymers, thepa ea mochini e bohlokoa haholo ho feta lisebelisoa tse ling tsa 'mele.Har'a lisebelisoa tsohle tse tsebahalang, li-polymers li na le mefuta e mengata ka ho fetisisa ea thepa ea mochini.Lebaka ke hore li-macromolecules li entsoe ka limolek'hule tse telele tsa ketane tse nang le thepa ea bohlokoa ea ho phomola ha molek'hule.Ha polymer elongation e phahame, bolelele ba ho robeha ha PE e tloaelehileng ke 90% ho 950% (linear low density polyethylene LLDPE e na le bolelele bo phahameng).Ka ts'ebetso e khethehileng ea tlhahiso, boleng ba bolelele ba lisebelisoa tse ling bo ka ba ho feta 1000%, 'me nako ea khefu ea thepa e tloaelehileng ea polymer e ka fihla ho 50% -10%.Ka kakaretso, filimi e nyenyefatsang mocheso, filimi e tsitsitseng, joalo-joalo, thepa e tsitsitseng ea litlhoko tse phahameng tsa thepa.

Ts'ebetso ea phepelo ea metsi ea HDPE e sebetsa hantle, ha ho bonolo ho e senya, bophelo bo bolelele ba ts'ebeletso.Haholo-holo e loketseng likopo tsa phepelo ea metsi.Tlhokomelo e etsoa nakong ea tšebeliso ho eketsa nako ea tšebeliso.
