Amandla aphezulu aphezulu emodulus polyethylene fiber abavelisi bazisa ukusebenza kwayo
(1) Ukuchasana kwempembelelo egqwesileyo
Ifayibha ye-UHMWPE yifayibha ye-thermoplastic enobushushu obuphantsi beglasi.Inokuqina okulungileyo kwaye ifunxa amandla kwinkqubo yokuguqulwa kweplastiki.Ngoko ke, izinto zayo ezidibeneyo zisenazo iimpawu ezintle zoomatshini kwizinga eliphezulu loxinzelelo kunye nobushushu obuphantsi.Ukuchasana kwempembelelo kuphezulu kunoko kwe-carbon fiber, i-arylon fiber kunye ne-glass fiber composite.Ifuthe elithile lilonke lokufunxa amandla e-Et/P ye-UHMWPE ifayibha ehlanganisiweyo yi-1.8, 2.6 kunye ne-3 amaxesha e-carbon fiber, i-aramide fiber kunye ne-E glass fiber, ngokulandelanayo.Ikhono le-bulletproof ye-UHMWPE ye-fiber composite ngamaxesha angama-2.5 aphezulu kune-aramide fiber.Amandla empembelelo yefayibha ye-UHMWPE iphantse yafana naleyo yenylon, kwaye ukufunxwa kwamandla e-UHMWPE ifayibha phantsi kwefuthe lesantya esiphezulu kuphindwe kabini ifayibha yePPTA kunye nefibre yenylon.Lo msebenzi ulungele kakhulu ukwenza izinto ezingenwe bulletproof.
(2) Ukusebenza kakuhle kokugoba
I-molecular weight polyethylene fiber ineempawu ezintle zokugoba kwaye inokwenza iikhoyili zokunitha kunye neentloko eziqhina ngaphandle kokwaphuka.Iipropathi zokugoba zefiber yeglasi, i-carbon fiber kunye ne-arylon fiber zihlwempuzekile.Ukuthelekisa iipropathi zokusetyenzwa kweentsinga ezahlukeneyo kubonisa ukuba i-molecular weight polyethylene inamandla aphezulu okubopha kunye namandla okwenza iringi, kwaye ifayibha ye-UHMWPE inomsebenzi ongcono wokwenza umsesane kunefayibha ye-aramid.
(3) Ukumelana ne-Creep yefiber
Ukusebenza kwe-creep ye-HSHMPE fiber kuxhomekeke kubushushu kunye nomthwalo wendawo yokusebenza.Ukusebenza kwe-creep ye-HSHMPE fiber kwi-35 ℃ kunye nomthwalo we-1g / d uboniswe kwiThebhile 3. Xa kuthelekiswa nefiber eqhelekileyo, ukusebenza kwe-creep resistance ye-HSHMPE fiber kuhle kakhulu.
(4) ukuxhathisa okulungileyo kokufuma kunye nokuxhathisa ukubola kweekhemikhali
Ngenxa yokwakheka kweekhemikhali ezilula ze-polyethylene, inokumelana nokugqwala okuhle.Iimveliso ezenziwe kule fiber aziyi kulahlekelwa amandla abo ngokuqhagamshelana ne-acids, i-alkali, amanzi olwandle angcolileyo, njl njl. I-fiber ye-UHMWPE ine-high molecular orientation kunye ne-crystallization, indawo ye-cross-sectional ye-macromolecules incinci, ngoko ke ilungiselelo lekhonkco lisondele, ukuze kuthintelwe ngokufanelekileyo ukhukuliseko lweemolekyuli zamanzi kunye ne-reagents yeekhemikhali, ukuze ibe nokumelana nokunyibilika okuhle kwe-solvent.Iifibers zeSpectra zigcina amandla azo ngokupheleleyo xa zintywiliselwa kwisiqingatha sonyaka kumajelo osasazo ahlukeneyo, njengamanzi, ioyile, iasidi, kunye nezisombululo ezisisiseko.I-Spectra fiber igcina amandla ayo emva kokuntywiliselwa emanzini ukuya kutsho kwiminyaka emibini kwaye iyakwazi ukumelana nokubola kwebhayoloji.Itheyibhile 1 --8 idwelisa ukugcinwa kwamandla e-Spectra fiber kunye ne-Kevlar fiber kwimidiya eyahlukeneyo yeekhemikhali.I-UHMWPE i-fiber macromolecular chain ayinayo nayiphi na iringi enuka kamnandi, iqela le-amino, iqela le-hydroxyl okanye amanye amaqela ekhemikhali asemngciphekweni wokuhlaselwa kwe-reagent esebenzayo, i-crystallinity iphezulu, ngoko ke amandla kwiindawo ezahlukeneyo ze-caustic agcinwa ngaphezulu kwe-90%, ngelixa i-aramid fiber in. iasidi eyomeleleyo, isiseko esomeleleyo siyancipha kakhulu.
(5) Nxiba ukuxhathisa
Ukumelana nokunxiba kwezinto ngokubanzi kuncipha kunye nemodyuli enkulu, kodwa kwifayibha ye-UHMWPE, intsingiselo ichasene, oku kungenxa ye-coefficient yayo ephantsi yokruthakruthwano, ngoko inokuqina okuphezulu.Intambo yefiber yeSpectra900PE inamaxesha ayi-8 aphezulu kumjikelo wokuqhawuka inani le-N kunefayibha ye-aramid, kwaye inamandla aphezulu okunxiba kunye nokugoba okudinwa kune-aramid fiber.Ngenxa yokucutshungulwa kwayo ngokulula, inethuba elihle lokusebenzisa kwishishini.Ukunxiba ukuxhathisa kwe-UHMWPE kwisithsaba seplastiki, amatyeli aliqela kunentsimbi ye-carbon, i-Huang Gang inxiba-ixhathisa, ukuxhathisa kwayo kuphindaphindwe kaninzi kune-polyethylene eqhelekileyo, kunye nobunzima obuphezulu bemolekyuli, ukusebenza okuxhathisayo kuphuculwa ngakumbi, kodwa emva kokuba ubunzima bemolekyuli bufikelela kwixabiso elithile, ukuxhathisa kwayo akusatshintshi kunye nobunzima obuphezulu bemolekyuli.
(6) Ukugquma kombane kunye nokumelana nokukhanya
Ukuhanjiswa kwe-UHMWPE ifayibha eyomeleziweyo edityanisiweyo ukuya kumaza e-radar iphezulu kuneyo yeglasi yefiber eyomeleziweyo yekhompositi ngenxa yedielectric ephantsi engaguqukiyo kunye namaxabiso elahleko ye-dielectric kwaye ambalwa abonakalisa amaza eradar.I-dielectric constant of polyethylene material kunye nexabiso lelahleko yokonga amandla lincinci, elilungele ukwenziwa kweeradomes ezahlukeneyo.Ukongezelela, amandla e-dielectric ye-UHMWPE malunga ne-700kV / mm, enokulawula ukuhanjiswa kwe-arc kunye ne-spark yombane.
Nangona emva kokukhanya kwe-1500h, izinga lokugcinwa kwamandla e-UHMWPE ifayibha malunga neepesenti ze-68, ngelixa ezinye iifayili zingaphantsi kweepesenti ze-50.
