Nsalu Yosapindika ya Basalt Fiber: "Chigoba Cholimbitsa" ndi "Chonyamulira Chogwira Ntchito" cha Zinthu Zophatikiza

Nsalu yosapindika ya basaltndi nsalu yopyapyala yolukidwa kuchokera ku nsalu yopitilira ulusi wa basalt (yosapindika kapena yopindika mofooka) pogwiritsa ntchito njira zosavuta zolukira monga zosavuta komanso zopindika. Phindu lake lalikulu ndi kukulitsa kusungidwa kwa mphamvu zamakanika ndi magwiridwe antchito a ulusi wa basalt kudzera mu kapangidwe kake ka "low twist + high continuity," zomwe zimapangitsa kuti ikhale substrate yoyenera kwambiri yolimbitsa thupi pantchito yopangira zovala zophatikizika.

1. Makhalidwe Abwino: Ubwino Wawiri wa Kusunga Magwiridwe Antchito ndi Kusintha kwa Njira

Kuchuluka Kwambiri kwa Makina Osungira: Kapangidwe kake "kosapindika" kamapewa kupsinjika kwamkati ndi kutayika kwa mphamvu komwe kumachitika chifukwa cha kupindika, zomwe zimapangitsa kuti mphamvu yokoka ndi modulus yotanuka ya nsaluyo ifike pamlingo wa yoyambirira. ulusi wa basalt(mphamvu yokoka imatha kufika pa 3000MPa, elastic modulus pafupifupi 90 ~ 110GPa), yoposa kwambiri ya Ulusi wa Galasi nsalu yosapindika yofanana ndi yomweyi.

Kunyowa bwino kwambiri: Kapangidwe ka nsalu kosasunthika, kofanana, kamapereka malo akuluakulu olumikizirana ndi ma resin (epoxy resin, unsaturated polyester resin, ndi zina zotero), zomwe zimathandiza kuti resin ilowe mwachangu, kuchepetsa zolakwika za thovu la mpweya m'kati mwa zovala zophatikizika, ndikuwonetsetsa kuti chinthu chomalizidwacho chili chokhazikika.

Kukhazikika kwamphamvu: Ulusi wa basalt ili ndi coefficient yotsika ya kukula kwa mzere (pafupifupi 6×10⁻⁶/℃), ndipo nsalu yosapindikaSichimakonda kufooka kapena kusweka chifukwa cha kusintha kwa kutentha kapena kupsinjika panthawi yopangira ndi kugwiritsa ntchito, zomwe zimapangitsa kuti chikhale choyenera kupanga zovala zophatikizika bwino kwambiri.

Kukana kwabwino kwa chilengedwe: Kulandira kukana kwa kutentha kwambiri komanso kotsika (kutentha kwa nthawi yayitali -260℃ ~ 650℃), asidi ndi alkali Kukana Kudzikundikira (kukhazikika kwapamwamba kwambiri ku mayankho monga hydrochloric acid ndi sodium hydroxide poyerekeza ndi ulusi wagalasi), komanso kukana ukalamba (palibe chiopsezo cha kuwonongeka kwa UV), ndi koyenera pamikhalidwe yovuta kwambiri yogwirira ntchito.

2. Phindu Lofunika Kwambiri: Kuchokera ku Kulimbitsa Kapangidwe mpaka Kugwira Ntchito

(1) Chovala Cholimbikitsidwa Chopangidwa ndi Zovala: "Pachimake Pawiri" cha Wopepuka ndi Mphamvu Zapamwamba

Nsalu yosapindikandi "chigoba" chachikulu cha basalt fiber reinforced polymer (BFRP), chomwe chimalowa m'malo mwa nsalu yagalasi ya fiberglass ndi carbon fiber, ndipo chimagwiritsidwa ntchito m'malo omwe mtengo ndi magwiridwe antchito zili bwino. Mu gawo la mayendedwe, chimagwiritsidwa ntchito mu zida zopepuka zamagalimoto (monga mapanelo a zitseko ndi zoteteza chassis), zida zoyendetsera sitima zapamtunda, ndi zigawo zolimbitsa sitima, zomwe zimapangitsa kuti thupi lichepetse ndi 30% ~ 50% pomwe chikuwonetsetsa kuti kapangidwe kake kakukana komanso kukana dzimbiri m'madzi a m'nyanja; mu gawo la zomangamanga ndi zomangamanga, ngati cholimbitsa zovala zolimbitsa mlatho, ngalande, ndi zigawo za konkire, chimapewa mavuto a dzimbiri ndikuwonjezera moyo wa kapangidwe kake (nthawi yogwira ntchito imatha kufika zaka zoposa 50) poyerekeza ndi zitsulo zachikhalidwe, ndipo chimagwiritsidwanso ntchito m'mapaipi a fiberglass ndi matanki osungira kuti chiwongolere kukana kuzizira kwa acid ndi alkali media; mu gawo la zovala zothandizira zamlengalenga, chimalowa m'malo mwa zovala zina zolimbitsa kaboni muzinthu zosanyamula katundu kapena zachiwiri zonyamula katundu monga ma bracket a satellite ndi ma drone fuselages ndi zabwino za "mtengo wotsika + magwiridwe antchito apamwamba," kuchepetsa ndalama zopangira.

(2) Chitetezo ndi Chonyamulira Chotenthetsera Chotentha Kwambiri: "Kusintha Moyenera" ku Zochitika Zogwira Ntchito

Kudalira mphamvu zake zotetezera kutentha kwambiri komanso mphamvu zotetezera kutentha, nsalu yosapindikaImakulitsa ntchito zake zoteteza mafakitale ndi zamagetsi. Ponena za zinthu zoteteza kutentha kwambiri, pambuyo pokonza (monga silicone rabara), imapangidwa kukhala mabulangeti ozimitsira moto, nsalu zoteteza kuwotcherera, ndi makatani oteteza kutentha amakampani achitsulo, omwe amatha kupirira kutentha kwambiri kwa nthawi yayitali kuposa 800°C popanda chiopsezo cha kusungunuka ndi kudontha, zomwe ndi zabwino kuposa zinthu zoteteza za fiberglass. Ponena za zovala zamagetsi zoteteza kutentha, monga chotetezera kutentha kapena tepi yokulunga ya ma mota ndi ma transformer, ili ndi dielectric loss tangent yotsika (20kV/mm), ndipo imalimbana ndi kukalamba kwa kutentha konyowa, komwe kumakwaniritsa zofunikira zogwira ntchito kwanthawi yayitali zamagetsi amphamvu kwambiri.
