Ubwihindurize bwo Gukora Ibendera: Isesengura ryuzuye, rishingiye ku makuru ku nyungu za FRP (Fibre Reinforced Polymer) Ibikoresho
2023-12-11 10:53:18
Imyenda ya societe yacu ikunze kugereranwa namabendera tuzamura - ibimenyetso byubumwe, indangamuntu, nubwibone. Nkibimenyetso byingirakamaro, inkingi zishyigikira aya mabendera zikwiye kwitabwaho mubwubatsi bwazo. Mu myaka yashize, gukora ibendera ryakorewe inzira y'ubwihindurize, kuva ku biti by'ibiti kugeza ku nkoni z'ibyuma. Uyu munsi, avant-garde muriyi domeni ni ibikoresho bya FRP (Fibre Reinforced Polymer), byerekana imbaraga zikomeye, kuramba, no guhuza n'imiterere. Dushingiye ku makuru afatika, turatanga isuzuma ryuzuye ryerekana impamvu FRP yihuta kuba igipimo cyizahabu mukubaka amabendera.

1. Uburemere na Imbaraga Paradigm:
- Imbaraga-Kuri-Ibipimo.
- FRP ifite imbaraga-uburemere bugereranije inshuro 20 kurenza ibyuma, ibikoresho bisanzwe. Ibinyuranye, aluminium, irindi hitamo ryamamaye, ifite igipimo kizenguruka inshuro 7-10 z'icyuma. Inshingano irasobanutse: FRP itanga imbaraga zingirakamaro hamwe nigice gito cyibiro, byorohereza ubwikorezi bworoshye nuburyo bunoze bwo kwishyiriraho ibiciro.
2. Kwihanganira Ibintu Byangirika:
- Binyuze mu kizamini cyumunyu (ASTM B117), dukura ubushishozi mukurwanya ruswa.
- Ibyuma, nubwo bikomeye, bitangira kugwa mu masaha 96 gusa.
- Aluminium, nubwo hari ukuntu ari nziza, itangira kwerekana piting nyuma yamasaha 200.
- Igitangaje, FRP ihagaze idacogora, ntagaragaza ibimenyetso byo gutesha agaciro na nyuma yamasaha 1.000. Iyi myigaragambyo ikomeye isobanura igihe kinini cyo kubaho kubirindiro bya FRP, cyane cyane mubidukikije byuzuyemo ibintu byangiza.
3. Kwunama ariko kutavunika - Ikizamini cyumuyaga:
- Ibendera rigomba kwihanganira uburakari bwa kamere, cyane cyane umuyaga uhuha.
- Ibiti by'ibyuma byageragejwe kwihanganira umuyaga ugera kuri 90hh.
- Inkingi ya Aluminium, nubwo ari nziza gato, isohoka nka 100hh.
- Ku rundi ruhande, FRP, yerekana ubuhanga budasanzwe, butwara umuyaga ugera kuri mph 120 utiriwe ufata. Uku guhuza n'imihindagurikire y'ikirere ntibisobanura gusa kuramba kw'ibendera gusa ahubwo binagira umutekano, cyane cyane mu bihe bibi.
4. Kwikingira - Umurinzi ucecetse:
- Imitungo ya FRP ituma itandukana cyane nicyuma.
- Kubijyanye nubushyuhe bwumuriro, FRP ipima 0.8 W / m · K, iri munsi cyane ya aluminium ya 205 W / m · K cyangwa ibyuma 43 W / m · K. Ibi bivuze ko FRP ikomeza kuba nziza nubwo haba hari ibihe byinshi.
- Amashanyarazi, FRP mubyukuri ntabwo ikora, inyungu ikomeye kurenza aluminium (37.7 x 10 ^ 6 S / m) hamwe nicyuma (6.99 x 10 ^ 6 S / m), cyane cyane mugihe cyinkuba cyangwa guhura utabishaka ninsinga z'amashanyarazi.
5. Kugumana ubujurire bwiza.
- Kugumana amabara ningirakamaro mugukomeza ibendera ryibendera.
- Ibizamini bya ASTM D2244 byerekana ko mugihe inkingi zicyuma zitangiye kuzimangana mugihe cyimyaka 2, FRP igumana hejuru ya 90% yamabara yayo meza nubwo nyuma yimyaka icumi. Ibara ryibanze muri FRP ryemeza isura ihamye, idashobora kwangirika, ikuraho akazi kenshi.
6. Inyungu z'igihe kirekire mu bukungu:
- Mu myaka icumi, amafaranga yo gufata neza ibyuma agera kuri 15% yikiguzi cyambere, ahanini biterwa no gusiga amarangi no kuvura ingese. Inkingi ya Aluminium, nubwo ari nziza gato, iracyategeka hafi 10% yikiguzi cyambere kubera kuvura pitingi na okiside.
- Mu buryo butandukanye cyane, inkingi ya FRP ikenera ikiguzi cyo gufata neza, munsi ya 2% yigiciro cyambere. Iyo uteganya ibiciro mumyaka icumi cyangwa irenga, imikorere yubukungu ya FRP iragaragara neza.
7. Guhitamo Ibidukikije:
- Ibendera rya FRP rishimangira ubwitange burambye.
- Ugereranije no gukora ibyuma, umusaruro wa FRP wohereza 15% munsi ya CO2. Umusaruro wa aluminium, ukunze kunengwa ingaruka z’ibidukikije, usohora CO2 hafi kabiri ugereranije n’ibyuma. Niyo mpamvu, FRP igaragara nkicyatsi kibisi, haba mubyakozwe ndetse no kuramba kwayo, bigabanya imyanda iterwa no gusimburwa.
Mu ncamake:
Ibendera, nubwo akenshi ryirengagizwa, ni sentine zicecetse zitwara ibimenyetso byubumwe nubwibone. Iyo turebye ku bikoresho bihuza imbaraga, kuramba, ubwiza, hamwe n’ibidukikije, FRP igaragara nkuwiruka imbere, itara ryo gukora ibendera rya kijyambere. Iri sesengura rishingiye ku makuru ashimangira ku buryo budashidikanywaho inyungu zitabarika FRP itanga, bigatuma ihitamo ryibanze ryibendera ryuyu munsi n'ejo.
