Bahlahisi ba matla a phahameng a phahameng a modulus polyethylene fiber ba hlahisitse ts'ebetso ea eona
(1) Tšusumetso e ntle ea ho hanyetsa
UHMWPE fiber ke faeba ea thermoplastic e nang le mocheso o tlase oa phetoho ea khalase.E na le toughness e ntle mme e monya matla ts'ebetsong ea deformation ea polasetiki.Ka hona, thepa ea eona e kopantsoeng e ntse e e-na le thepa e ntle ea mochine ka tekanyo e phahameng ea khatello le mocheso o tlaase.Khanyetso ea tšusumetso e phahame ho feta ea carbon fiber, arylon fiber le metsoako ea khalase ea fiber.Tšusumetso e khethehileng ea matla a ho monya Et/P ea motsoako oa fiber ea UHMWPE ke makhetlo a 1.8, 2.6 le a 3 a fiber ea carbon, fiber ea aramide le fiber ea khalase ea E, ka ho latellana.Bokhoni ba likulo ba motsoako oa fiber ea UHMWPE bo phahame ka makhetlo a 2.5 ho feta fiber ea aramide.Matla a tšusumetso ea fiber ea UHMWPE a batla a tšoana le a nylon, 'me ho monngoa ha matla ha fiber ea UHMWPE tlas'a tšusumetso ea lebelo le phahameng ho habeli ho feta fiber ea PPTA le fiber ea nylon.Tshebetso ena e loketse haholo bakeng sa ho etsa lisebelisoa tse thibelang likulo.
(2) Ts'ebetso e ntle ea ho khumama
Polyethylene fiber e phahameng ea boima ba molek'hule e na le mekhoa e metle ea ho kobeha 'me e ka etsa likhoele tsa ho loha le lihlooho tse tlamang ntle le ho robeha.Lintho tse kobehang tsa fiber ea khalase, fiber ea carbon le fiber ea arylon ha li ntle.Papiso ea thepa ea ho sebetsa ea likhoele tse fapaneng e bonts'a hore polyethylene e boima ba molek'hule e na le matla a holimo a tlamahano le matla a ho etsa lesale, 'me fiber ea UHMWPE e na le ts'ebetso e ntle ea ho etsa lesale ho feta fiber ea aramid.
(3) Khanyetso ea Creep ea fiber
Ts'ebetso ea creep ea HSHMPE fiber e itšetlehile ka mocheso le mojaro oa tikoloho ea ts'ebetso.Ts'ebetso ea creep ea HSHMPE fiber ho 35 ℃ le 1g / d mojaro e bontšoa ho Lethathamo la 3. Ha e bapisoa le fiber e tloaelehileng, ts'ebetso ea khanyetso ea creep ea HSHMPE fiber e ntle haholo.
(4) ho hanyetsa mongobo hantle le lik'hemik'hale tsa kutu ea lik'hemik'hale
Ka lebaka la sebopeho se bonolo sa lik'hemik'hale sa polyethylene, se na le khanyetso e ntle ea kutu.Lihlahisoa tse entsoeng ka fiber ena li ke ke tsa lahleheloa ke matla a tsona ka ho kopana le li-acids, alkalis, metsi a leoatle a litšila, joalo-joalo UHMWPE fiber e na le mokhoa o phahameng oa limolek'hule le crystallization, sebaka sa cross-sectional sa macromolecules se senyenyane, kahoo tlhophiso ea ketane e haufi, e le ho thibela ka katleho khoholeho ea limolek'hule tsa metsi le lik'hemik'hale tsa lik'hemik'hale, e le hore e be le khanyetso e ntle ea solvent solubility.Li-Spectra fibers li boloka matla a tsona ka ho feletseng ha li qoelisoa halofo ea selemo mecheng ea litaba e fapaneng, e kang metsi, oli, asiti le litharollo tsa motheo.Fiber ea Spectra e boloka matla a eona ka mor'a ho qoelisoa ka metsing ho fihlela lilemo tse peli 'me e boetse e hanyetsana le ho bola ha likokoana-hloko.Lethathamo la 1 --8 le thathamisa matla a ho boloka matla a Spectra fiber le Kevlar fiber mecheng ea litaba tse fapaneng tsa lik'hemik'hale.UHMWPE fiber macromolecular chain ha e na reng efe kapa efe e nkhang hamonate, sehlopha sa amino, sehlopha sa hydroxyl kapa lihlopha tse ling tsa lik'hemik'hale tse kotsing ea tlhaselo ea reagent e sebetsang, crystallinity e phahame, kahoo matla a tikolohong e fapaneng ea caustic a bolokiloe ho feta 90%, ha fiber ea aramid e le teng. acid e matla, setsi se matla se fokotseha haholo.
(5) Apara khanyetso
Ho hanyetsa ho roala ha thepa ka kakaretso ho fokotseha ka modulus e kholo, empa bakeng sa fiber ea UHMWPE, mokhoa ona o fapane, sena ke ka lebaka la coefficient ea eona e tlaase ea likhohlano, kahoo e na le nako e telele ea nako e telele.Thapo ea faeba ea Spectra900PE e na le nomoro ea cycle ea ho robeha ka makhetlo a 8 ho feta fiber ea aramid, 'me e na le matla a ho khathala a holimo ho feta aramid fiber.Ka lebaka la ts'ebetso ea eona e bonolo, e na le tebello e ntle ea ts'ebeliso indastering.Apara khanyetso ea UHMWPE moqhaka oa polasetiki, makhetlo a 'maloa ho feta tšepe ea carbon, Huang Gang e haneloa, ho hanyetsa ha eona ho feta makhetlo a mangata ho feta polyethylene e tloaelehileng,' me ka boima bo phahameng ba limolek'hule, ts'ebetso e thibelang ho roala e ntlafatsoa le ho feta, empa ka mor'a hore boima ba molek'hule bo fihle boemong bo itseng, ho hanyetsa ha eona ha ho sa fetoha ka boima bo phahameng ba molek'hule.
(6) Ho kenya motlakase le ho hanyetsa khanya
Phetisetso ea likhomphutha tse matlafalitsoeng tsa fiber ea UHMWPE ho maqhubu a radar e phahame ho feta ea likhalase tse matlafalitsoeng ka likhalase ka lebaka la boleng bo tlase ba dielectric le tahlehelo ea dielectric le maqhubu a seng makae a bonts'ang radar.Thepa ea dielectric ea polyethylene le boleng ba tahlehelo ea matla e nyane, e loketseng ho etsoa ha li-radomes tse fapaneng.Ho phaella moo, matla a dielectric a UHMWPE a ka bang 700kV / mm, a ka laolang ho fetisoa ha arc le spark ea motlakase.
Le kamora khanya ea 1500h, sekhahla sa ho boloka matla sa fiber ea UHMWPE se ka ba liperesente tse 68, athe likhoele tse ling li ka tlase ho liperesente tse 50.
