CHIKWANGWANI cha UHMWPE chili ndi zinthu zambiri zabwino kwambiri, monga makina abwino kwambiri, kukana kwamphamvu kwambiri, kukana kuvala bwino, kukana kwa dzimbiri, kukana kwamphamvu kwamagetsi ndi zina zambiri.
1. Makina abwino kwambiri a UHMWPE fiber.
UHMWPE CHIKWANGWANI chili ndi makina abwino kwambiri. Pansi pa kachulukidwe komweko, mphamvu yamakokedwe ya UHMWPE CHIKWANGWANI ndi kuwirikiza ka 15 kuposa chingwe chachitsulo chachitsulo. Ndiwokwera 40% kuposa ulusi wa aramid, womwenso ndi umodzi mwamipangidwe itatu yapamwamba kwambiri padziko lonse lapansi, komanso nthawi 10 kuposa ulusi wachitsulo wapamwamba kwambiri komanso ulusi wamankhwala wamba. Poyerekeza ndi chitsulo, E-galasi, nayiloni, polyamine, carbon fiber ndi boron fiber, mphamvu zake ndi modulus ndizoposa zazitsulozi, ndipo mphamvu zake ndizopamwamba kwambiri pakati pa zipangizo zamtundu womwewo.
2.Kukaniza kwakukulu kwa UHMWPE fiber
Ultra high molecular weight polyethylene fiber imakhala ndi kukana kwambiri. Kuthekera kwake kutengera mphamvu ndikukana kukhudzidwa panthawi yopindika ndi kuumbidwa ndikwapamwamba kuposa ulusi wa aramid ndi kaboni fiber, zomwenso ndi "zingwe zitatu zapamwamba kwambiri padziko lapansi". Poyerekeza ndi polyamide, aramid, E glass fiber, carbon fiber ndi aramid fiber, UHMWPE fiber imakhala ndi mayamwidwe apamwamba kwambiri kuposa mphamvu.
3. Kukana kovala bwino kwa UHMWPE fiber
Nthawi zambiri, ma modulus akakula kwambiri, kumachepetsa kukana kwazinthu, koma kwa fiber ya UHMWPE, zosiyana ndizowona. Chifukwa CHIKWANGWANI cha UHMWPE chimakhala ndi kagawo kakang'ono kakukangana, kukulitsa modulus, kumapangitsa kukana kuvala. Poyerekeza ndi friction coefficient ya UHMWPE fiber ndi ya carbon fiber ndi aramid fiber, kukana kuvala ndi kutopa kopindika kwa UHMWPE fiber ndizokwera kwambiri kuposa za carbon fiber ndi aramid fiber. Choncho kukana kwake kuvala kuli bwino kusiyana ndi ulusi wina wapamwamba kwambiri. Chifukwa cha kukana kwake kovala bwino komanso kukana kupindika, ntchito yake yokonza ndi yabwino kwambiri, ndipo ndiyosavuta kupangidwa kukhala zinthu zina zophatikizika ndi nsalu.
4.Chemical dzimbiri kukana UHMWPE CHIKWANGWANI
Kapangidwe kakemidwe ka CHIKWANGWANI ka UHMWPE n'kosavuta ndipo mankhwala ake ndi okhazikika. Kuphatikiza apo, imakhala ndi mawonekedwe a crystalline kwambiri, omwe amapangitsa kuti asakhale pachiwopsezo cha kuukira kwa majini olimba mu ma acid amphamvu ndi maziko amphamvu, ndipo amatha kukhalabe ndi zida zake zoyambira komanso kapangidwe kake. Choncho, mankhwala ambiri zinthu si zophweka dzimbiri izo. Mayankho ochepa chabe a organic omwe amatha kukulitsa pang'ono, ndipo kuwonongeka kwake kwamakina kumachepera 10%. Kusungidwa kwa mphamvu kwa UHMWPE fiber ndi fiber aramid mumitundu yosiyanasiyana yamankhwala kunayerekezedwa. Kukana kwa dzimbiri kwa CHIKWANGWANI cha UHMWPE mwachiwonekere ndikwambiri kuposa ulusi wa aramid. Ndiwokhazikika makamaka mu asidi, alkali ndi mchere, ndipo mphamvu zake zimangotayika mu sodium hypochlorite solution.
5.Kukana kuwala kwabwino kwa UHMWPE fiber
Chifukwa kapangidwe kake ka ulusi wa UHMWPE ndi wokhazikika, kukana kwake kumakhalanso kopambana pakati pa ulusi wapamwamba kwambiri. Ulusi wa Aramid sulimbana ndi UV ndipo ungagwiritsidwe ntchito pokhapokha popewa kuwala kwa dzuwa. Poyerekeza CHIKWANGWANI cha UHMWPE ndi nayiloni, aramid yokhala ndi modulus yayikulu komanso yotsika modulus, kusungidwa kwamphamvu kwa UHMWPE fiber ndikokwera kwambiri kuposa ulusi wina.
6.Zinthu zina za UHMWPE fiber
CHIKWANGWANI cha UHMWPE chilinso ndi katundu wabwino wa hydrophobic, kukana kwamadzi ndi chinyezi, katundu wamagetsi wamagetsi komanso moyo wautali wovutitsa. Ndi fiber yokhayo yapamwamba kwambiri yomwe imatha kuyandama pamadzi, komanso ndi chinthu choyenera kutentha kwambiri.
Koma ilinso ndi zovuta zake, ndiko kuti, malo osungunuka ndi otsika. Pakukonza, kutentha sikuyenera kupitirira 130 ℃, apo ayi, chodabwitsa chidzachitika ndipo moyo wautumiki udzafupikitsidwa chifukwa cha mphamvu yofooka pakati pa maunyolo amtundu wa UHMWPE. Palibe gulu la utoto pa ulusi wa UHMWPE, womwe umapangitsa kunyowa kwake kukhala kosauka. Ndizovuta kuti utoto ulowe mu ulusi, zomwe zimapangitsa kuti utoto usagwire bwino ntchito. Zolakwika izi zimakhudza kukula kwa ntchito yake.
