Kukwezva kweBasalt Fiber
Pfungwa yekugadzira fibers kubva kubasalt haisi itsva. Yekutanga patent yekugadzira basalt fiber yakapihwa muna 1923, uye mukati me1950s nema1960s, tsvakiridzo yakakura yakanangana nekushandiswa kwayo kwechiuto. Kutotungamira Girazi Fiber vagadziri vakaongorora kugona kwebasalt panguva iyoyo, kunyangwe vakashandura kutarisa kwavo kweR&D muma1970 kuenda kumhando yepamusoro-yegirazi fibers seS-2. Kwemakumi emakore, kufarira basalt fiber composites kwakachinja, asi mumakore achangopfuura, yakawedzera zvishoma nezvishoma.
Tichifunga kuti basalt inotangira kubva kune magnesium- uye iron-rich lava inokurumidza kunyoroveswa mudombo, hazvishamisi kuti basalt fibers inoratidza yakasarudzika yekupisa yekupisa, kudzivirira moto, uye kugadzikana kwepamusoro-tembiricha. Izvi zvimiro zvinovaita zvakajairwa zvinhu zvepamusoro-tembiricha insulation. Semuyenzaniso, mugadziri weRussia basalt fiber Kamenny Vek anopa indasitiri yemotokari yeUS nezvigadzirwa zvekuburitsa system insulation uye inopa zvinhu zvinodzivirira kupisa zvekushandisa mumaindasitiri.
Kupfuura thermal performance, basalt fiber's musanganiswa wesimba, kuoma, kukanganisa kuramba, uye Chemical inertness inoita kuti ive yekusimbisa inoyevedza kune macomposites. Mune fiber-reinforced plastic (FRP) maapplication, maitiro ayo ekuumba akafanana neaya egirazi fiber. Inenge chero girazi fiber molding tekinoroji inogona kuchinjirwa basalt fiber ine zvidiki zvigadziriso kune akakosha paramita. Basalt fiber inowiriranawo neese akajairwa resin masisitimu.
Kunyangwe huremu hwebasalt (2.63 g/cm³) hwakati darikei pane girazi faibha, mabhenefiti ayo ekuita anogonesa kureruka uye mamwe dhizaini-anochinjika macomposites.
Basalt fiber's thermal properties iri kuwana tarisiro kupfuura insulation. Macomposites ayo ari kuwedzera kushandiswa mumashandisirwo anoda huwandu hwekushisa. Kupikisa kwaro kunowedzerawo girazi uye carbon fibers. Zvidzidzo zvekutanga neGermany Integrative Lightweight Construction Center neTextile Technology Institute paRWTH Aachen University zvakaratidza kuti basalt hybrid yarn jira (HYWF)-yakasimbiswa polyamide 6 inotora 35% yakananga simba pane girazi faibha HYWF uye 17% kupfuura kabhoni faibha HYWF.
Iron uye aluminium oxides mubasalt inobatsira kune mamwe mabhenefiti. Semuyenzaniso, basalt faibha inoratidzira zvirinani kuonda nekudzikisira moto pane E-girazi. Ongororo yakaitwa neIreland's Mafic neCanada's Fraunhofer Project Center yakasimbisa kuti basalt fiber/epoxy test panels vakawana 40% yakakwirira tensile modulus, tensile simba, uye interlaminar shear simba, pamwe ne20% yakakura kuomarara, zvichienzaniswa neE-girazi/epoxy mapaneru akagadzirwa neresin imwechete uye maitiro. Kamenny Vek ataura mhedzisiro yakafanana.
Basalt fiberKunyura kwemvura kwakadzikira kwakakosha pakuvaka uye kushandiswa kwepombi. Haisi-conductive uye, sechinhu chinongoitika, chiri nyore kudzokorodza pane zvekugadzira fibers-yakakosha kufunga nezvemotokari uye mamwe maindasitiri. Gencarelle inotsanangura basalt fiber se "yakaonda, yakasvibira, uye yakaoma" pane dzimwe nzira, ichiisa macomposites ayo sebhiriji rekuita-mutengo pakati peE-girazi necarbon fiber. Sezvakataurwa naThompson, "Tiri kuzadza mukaha uripo pakati pekabhoni negirazi fibers-musika unoshuvira mhinduro yakadaro."
Kuchinja kubva kucarbon kuenda kubasalt fiber kunonzi kuri nyore pane kuchinja kubva kuE-girazi, kunyangwe zvese zviri kuitika. Kune vashandisi vekabhoni fiber, mari yekuchengetedza inofambisa shanduko, nepo basalt yakaenzana kuita-kune-mutengo reshiyo inokodzera maapplication uko kabhoni-yepamusoro-yepamusoro performance isingakoshe. Maitiro avo ekukundikana anosiyanawo: kabhoni fiber inotadza kutadza zvakanyanya (semuenzaniso, kuparara), nepo basalt fiber inoratidza zvishoma nezvishoma, kukundikana kwakachengeteka. Streetman anoenzanisira, kuti: “Gumbo resimbi rinoumbwa nekabhoni rinofa kamwe kamwe, richikonzera kuwa; gumbo rinoumbwa nebasalt rinobvumira mushandisi kugara pasi.”
Nepo kuvandudzwa kwekugadzira kuri kuderedza mitengo, basalt fiber inoramba ichidhura zvakapetwa kaviri seE-girazi mune yakakwirira-vhoriyamu application. Kururamisa iyo premium, hukuru hwayo humiro-hukuomeswa kwepamusoro, simba, kukanganisa kupikisa, makemikari / mvura kuramba, uye yakachengeteka kutadza modes-inofanirwa kuendesa kukosha kwakakosha. Sezvo tekinoroji ichifambira mberi, dombo rinoputika iri kuveza niche yakasarudzika munyika yezvinhu zvepamberi.
