Girazi faibha ine zvakawanda zvakanaka zvakadai sesimba rakakwirira uye uremu huremu, kushorwa kwecorrosion, kushomeka kwekushisa kwepamusoro, kuita kwakanaka kwemagetsi ekudzivirira, etc. Ndiyo imwe yezvinowanzo shandiswa mbishi zvinhu zvinoumba composite.Panguva imwecheteyo, China ndiyo zvakare inogadzira pasi rose yegirazi fiber.
1. Chii chinonzi fibergirazi?
Girazi faibha is an inorganic non-metallic material ine mashandiro akanakisa, is a natural mineral with silica as the main raw material, wedzera chaiyo simbi oxide mineral raw materials, yakasanganiswa zvakafanana, yakanyungudutswa pakupisa kwepamusoro, yakanyungudutswa yegirazi mvura inoyerera nepa funnel outflow, basa repamusoro-speed kudhonza simba rinokwevera rinokweva uye nekukasira kutonhodzwa uye kuporeswa kuita faibha yakanaka kwazvo inoenderera.
Girazi fiber monofilament dhayamita kubva kune mashoma mamicrons kusvika kune anopfuura makumi maviri mamicrons, akaenzana nevhudzi re1 / 20-1 / 5, rimwe nerimwe bundle re fiber rinoumbwa nemazana kana kunyange zviuru zve monofilaments.
Girazi faibha basic zvimiro:Kutaridzika kweyakatsetseka cylindrical pamusoro, muchinjiko-chikamu denderedzwa rakazara, rakatenderedzwa muchinjiko-chikamu kuti rimire kuremerwa;gasi uye mvura kuburikidza nekupikisa idiki, asi iyo yepamusoro inotsvedza kuitira kuti simba rekubata refiber ridiki, risingafambisi kusanganiswa neresin;density inowanzo mu 2.50-2.70 g / cm3, zvichienderana zvakanyanya nekugadzirwa kwegirazi;kusimba kwesimba kupfuura mamwe mafibhi echisikigo, masisitimu ekugadzira ave akakwirira;brittle zvinhu, kureba panguva yekuzorora kudiki kwazvo Kupokana kwemvura uye asidi kuramba kwakanaka, nepo alkali kuramba kwakashata.
2.Girazi fiber classification
Inogona kukamurwa kuita inoenderera girazi fiber, pfupi girazi fiber (yakagadzika kureba girazi fiber) uye refu girazi fiber (LFT) kubva pakureba kupatsanurwa.
Kubva pane alkali simbi yemukati inogona kukamurwa kuita alkali-isina, yakaderera, yepakati uye yakakwira, kazhinji yakagadziridzwa nealkali-isina, kureva, E girazi faibha, shanduko yemumba inowanzoshandiswa E girazi fiber.
3.Chii chinogona kushandiswa girazi fiber
Girazi faibha ine yakakwira kusimba simba, kunyungudika, kusapisa, makemikari kuramba, kunyura kwemvura yakaderera, kuita kwakanaka kwekugadzirisa uye humwe hunhu hwakanaka, kazhinji sechinhu chinoumbwa mune inosimbisa zvinhu, magetsi ekudzivirira zvinhu uye zvekudzivirira, redunhu substrate, nezvimwe. ., inoshandiswa zvakanyanya munzvimbo dzakasiyana-siyana.
Kune dzimwe nyika girazi fiber yakakamurwa kuita zvikamu zvina maererano nekushandiswa kwechigadzirwa: inosimbisa zvinhu zve thermosetting mapurasitiki, girazi faibha inosimbisa zvinhu zve thermoplastics, simende gypsum yekusimbisa zvinhu, uye girazi fiber textile zvinhu, izvo zvinosimbisa zvinhu zvinomiririra 70-75% uye girazi. fiber textile zvinhu zvinokwana 25-30%.Kubva pakudiwa kwemvura yakadzika, zvivakwa zvinokwana 38% (kusanganisira pombi, kubvisa munyu, kudziya kwemba uye kudzivirira mvura, kuchengetedza mvura, nezvimwewo), zvekufambisa zvinokwana 27-28% (yacht, mota, njanji inomhanya, nezvimwewo) uye zvemagetsi zvinokwana 17%.
To sum up, nzvimbo dzekushandisa dzegirazi faibha dzinenge dzekufambisa, zvekuvakisa, indasitiri yemagetsi, indasitiri yemagetsi, indasitiri yepetrochemical, nhandaro netsika, uye tekinoroji yekudzivirira yenyika.
