Simba repamusoro rakakwirira modulus polyethylene fiber vagadziri vakaunza mashandiro ayo
(1) Yakanakisa kukanganisa kupikisa
UHMWPE faibha ndeye thermoplastic faibha ine yakaderera girazi shanduko tembiricha.Iine kusimba kwakanaka uye inotora simba mukuita kwepurasitiki deformation.Naizvozvo, zvinhu zvaro zvakasanganiswa zvichine zvakanaka zvemichina padanho repamusoro uye tembiricha yakaderera.Iko kukanganisa kupikisa kwakakwira kupfuura iyo kabhoni fiber, arylon fiber uye girazi fiber composite.Iyo chaiyo inokonzeresa yekunyudza simba Et/P yeUHMWPE faibha inoumbwa ndeye 1.8, 2.6 uye 3 nguva iyo yecarbon fiber, aramide faibha uye E girazi fiber, zvichiteerana.Iyo bulletproof kugona kweUHMWPE faibha composite ndeye 2.5 times yakakwirira kupfuura iyo aramide fiber.Kusimba kwesimba reUHMWPE faibha rinenge rakangofanana neironi, uye kunyudzwa kwesimba kweUHMWPE faibha pasi pekumhanya kwakanyanya kakapetwa kaviri kwePPTA faibha uye naironi faibha.Kuita uku kwakanyatsokodzera kugadzira zvinhu zvisingapindi bara.
(2) Kuita kwakanaka kwekukotama
Yakakwira molecular huremu polyethylene faibha ine yakanaka yekukotama zvivakwa uye inogona kugadzira makoiri ekuruka uye kupfumba misoro pasina kutyoka.Iyo yekukotama zvimiro zvegirazi fiber, kabhoni faibha uye arylon fiber hazvina kunaka.Kuenzanisa kwekugadzirisa zvivakwa zvemafayibha akasiyana-siyana kunoratidza kuti yakakwira molecular uremu polyethylene ine yakakwira bonding simba uye mhete yekugadzira mhete, uye UHMWPE faibha ine zvirinani kuumba ring performance pane aramid fiber.
(3) Creep kuramba fiber
Iyo inokambaira kuita kweHSHMPE fiber inoenderana nekupisa uye mutoro wenzvimbo yekushandisa.Iyo inokambaira yeHSHMPE fiber pa 35 ℃ uye 1g / d mutoro inoratidzwa muTebhu 3. Inofananidzwa neyakajairwa fiber, creep resistance performance yeHSHMPE fiber yakanakisa.
(4) yakanaka mwando kuramba uye kemikari ngura kuramba
Nekuda kwechimiro chakareruka chemakemikari ye polyethylene, ine yakanaka corrosion resistance.Zvigadzirwa zvakagadzirwa nefiber iyi hazvizorasikirwi nesimba razvo nekusangana neasidhi, alkali, mvura yegungwa yakasviba, etc. UHMWPE fiber ine high molecular orientation uye crystallization, nzvimbo ye-cross-sectional macromolecules iduku, saka urongwa hweketani huri pedyo, kuitira kuti zvibudirire kudzivirira kukukurwa kwemamorekuru emvura uye kemikari reagents, kuitira kuti ive neyakagwinya solubility resistance.Spectra fibers inochengetedza simba rayo zvachose kana yakanyudzwa kwehafu yegore mune dzakasiyana siyana media, senge mvura, oiri, asidhi, uye base mhinduro.Iyo Spectra fiber inochengetedza simba rayo mushure mekunyudzwa mumvura kweanosvika makore maviri uye zvakare inoshingirira kune biological corrosion.Tafura 1 - 8 inonyora kuchengetedza kwesimba kweSpectra fiber uye Kevlar fiber mune akasiyana makemikari media.UHMWPE fiber macromolecular chain haina chero rin'i inonhuhwirira, boka reamino, boka rehydroxyl kana mamwe mapoka emakemikari ari panjodzi yekurwiswa reagent, iyo crystallinity yakakwira, saka simba munzvimbo dzakasiyana-siyana dze caustic rinochengetwa kupfuura 90%, nepo aramid fiber in. asidhi yakasimba, hwaro hwakasimba hunoderera zvakanyanya.
(5) Pfeka kuramba
Kupfeka kwekupokana kwechinhu kunowanzo kuderera neiyo hombe modulus, asi kune UHMWPE fiber, maitiro anopesana, izvi imhaka yeyakaderera coefficient yekupokana, saka ine yakanyanya kusimba.Spectra900PE faibha tambo ine 8 yakapetwa kasere yekupwanya kutenderera nhamba N pane aramid fiber, uye ine yakakwira kupfeka nekukotama kuneta simba kupfuura aramid fiber.Nekuda kwekugadzirisa kwayo kuri nyore, ine tarisiro yakanaka yekushandisa muindasitiri.Pfeka kuramba kweUHMWPE mukorona yepurasitiki, kakawanda kupfuura kabhoni simbi, Huang Gang kupfeka-resisting, kusamira kwayo kupfeka kwakapetwa kakapetwa kakawanda kupfuura polyethylene yakajairwa, uye nehupamhi hwema molecular mass, kusapfeka-kuramba kuita kunowedzera kuvandudzwa, asi. mushure mekunge ma molecular mass inosvika pahumwe kukosha, kusamira kwayo hakuchashanduki nehupamhi hwema molecular mass.
(6) Kuvharirwa kwemagetsi uye kupikisa chiedza
The transmittance of UHMWPE fiber reinforced composites kumafungu eradar yakakwirira kudarika iyo yegirazi fiber reinforced composite nekuda kweiyo yakaderera dielectric inogara uye dielectric kurasikirwa kukosha uye mashoma anoratidza radar masaisai.Iyo dielectric yenguva dzose ye polyethylene zvinhu uye simba rekuchengetedza kurasikirwa kukosha idiki, iyo yakakodzera kugadzirwa kweakasiyana radomes.Pamusoro pezvo, iyo dielectric simba reUHMWPE rinenge 700kV/mm, iro rinogona kudzora kutamiswa kwearc uye spark yemagetsi.
Kunyangwe mushure mekuvhenekerwa kwe1500h, chiyero chekuchengetedza simba cheUHMWPE fiber chinenge 68 muzana, nepo mamwe mafiber ari pasi pe50 muzana.
