Fiber Glass ine mabhenefiti akasiyana senge kusimba kwesimba, huremu huremu, corrosion resistance, tembiricha yakakwira, uye kuita kwakanaka kwemagetsi ekudzivirira, izvo zvinoita kuti ive imwe yezvinhu zvinowanzo shandiswa zvinoumbwa.Panguva imwecheteyo, China zvakare ndiyo inogadzira pasi rose fiberglass.
1) chii chinonzi fiberglass?
Girazi faibha is inorganic isiri-metallic zvinhu zvine mashandiro akanaka.Icho chicherwa chechisikigo chinonyanya kugadzirwa nesilika, ine chaiyo simbi oxide mineral raw materials yakawedzerwa.Mushure mekusanganiswa zvakaenzana, inonyunguduka pakupisa kwepamusoro, uye mvura yegirazi yakanyungudutswa inoyerera ichibuda nemumuromo wekudonha.Pasi pesimba rekumhanya-mhanya, inotambanudzwa uye inokurumidza kutonhodzwa uye yakasimbiswa kuita mafibhi akanyanya kunaka anoenderera.
Iyo dhayamita yegirazi fiber monofilament inotangira kubva kune mashoma mamicrons kusvika anopfuura makumi maviri mamicrons, akaenzana ne1 / 20-1 / 5 yebvudzi, uye imwe neimwe bundle yefiber inoumbwa nemazana kana kunyange zviuru zvemonofilaments.
Basic zvimiro zvegirazi fiber: Chitarisiko chakapfava cylindrical chimiro chine yakazara denderedzwa muchinjiko-chikamu, uye denderedzwa muchinjiko-chikamu chine simba rekutakura mutoro;Gasi uye mvura ine kushomeka kwepasi, asi nzvimbo yakatsetseka inoderedza kuwirirana kwemafibers, izvo zvisingakodzeri kubatana neresin;Density inowanzova pakati pe2.50 ne2.70 g/cm3, kunyanya zvichienderana nekuumbwa kwegirazi;Kusimba kwesimba kwakakwira kupfuura mamwe masikirwo faibha uye synthetic fibers;Brittle zvinhu zvine kureba kwakadzika kwazvo panguva yekuzorora;Mvura yakanaka uye kupikisa asidhi, asi kushomeka kwe alkali.
2) Girazi fiber classification
Nekureba kupatsanurwa, inogona kukamurwa kuita inoenderera girazi fiber, pfupi girazi fiber (yakagadziriswa kureba girazi fiber), uye refu girazi fiber (LFT).
Kuenderera mberi kwegirazi fiber parizvino ndiyo inonyanya kushandiswa girazi fiber muChina, iyo inowanzonzi "refu fiber".Vagadziri vanomiririra Jushi, Mount Taishan, Xingwang, nezvimwe.
Fixed urefu hwegirazi fiber inowanzonzi "short fiber", iyo inowanzo shandiswa nekunze-inopihwa mari yekugadziridza zvidyarwa uye mamwe mabhizinesi epamba.Vagadziri vanomiririra iPPG, OCF uye yepamba CPIC, uye nhamba diki yeJushi Mount Taishan.
LFT yakabuda muChina mumakore achangopfuura, nevagadziri vanomiririra vanosanganisira PPG, CPIC, uye Jushi.Parizvino, mabhizinesi epamba akadai seJinfa, Shanghai Nayan, Suzhou Hechang, Jieshijie, Zhongguang Nuclear Juner, Nanjing Julong, Shanghai Pulit, Hefei Huitong, Changsha Zhengming, uye Rizhisheng ese ane kugadzirwa kwakawanda.
Zvinoenderana nealkali metal content, inogona kupatsanurwa kuita alkali isina, yakaderera yepakati yakakwira, uye kazhinji yakagadziridzwa uye yakasimbiswa nealkali isina, kureva E-girazi faibha.MuChina, E-girazi fiber inowanzoshandiswa kugadzirisa.
3) Kushandisa
Zvinoenderana nekushandiswa kwechigadzirwa, zvakakamurwa kuita zvikamu zvina: zvakasimbiswa zvinhu zve thermosetting mapurasitiki, girazi faibha yakasimbisa zvinhu zve thermoplastics, simende gypsum yakasimbisa zvinhu, uye girazi fiber textile zvinhu.Pakati pavo, zvinhu zvakasimbiswa zvinokwana 70-75%, uye girazi fiber textile zvinhu zvinokwana 25-30%.Kubva pakuona kwekuda kwemvura yakadzika, zvivakwa zvinokwana 38% (kusanganisira mapaipi, kuchenesa mvura yegungwa, kupisa kwemba uye kudzivirira mvura, kuchengetedza mvura, nezvimwewo), zvekufambisa zvinokwana 27-28% (yachts, mota, njanji inomhanya kwazvo, etc.), uye zvemagetsi zvinokwana 17%.
