Yakasiyana-siyana ye fiberglass zvigadzirwa
Fiberglass chinhu chakanyanya kunaka inorganic isiri-simbi zvinhu.Girazi fiberrudzi rwechisikigo chisiri-metallic ore senge leucolite, pyrophyllite, kaolin, jecha requartz, limestone, etc. High-grade inorganic fibers ine dhayamita imwe chete yefilament ye microns shoma kusvika kune 20 microns, iyo yakaenzana ne1. /20-1/5 yebvudzi.
Kune marudzi akawanda egirazi fiber, iyo inokodzera mamiriro akasiyana.Girazi fiber inogona kugoverwa mumhando dzakasiyana-siyana maererano nekuumbwa, zvakadai se-non-alkali, medium-alkali, high-alkali, high-simba, boron-isina uye isiri-alkali, etc. Kuita kwakasiyana, uye kunoshandiswa. muminda yakasiyana zvichienderana nemaitiro ayo ekuita.Semuyenzaniso, magirazi faibha ane alkali simbi oxide yemukati isingasviki 0.8%.alkali-isina girazi fibers, iyo ine zvakanaka magetsi ekudzivirira uye mechanical properties, asi yakashata acid resistance, saka inoshandiswa zvakanyanya muzviitiko zvinoda kuvharwa kwemagetsi kana muFRP;Zviri mukati 11.9% -16.4% ndezvepakati-alkali girazi faibha, iyo ine yakasimba asidhi inodzivirira asi isina kunaka kushanda kwemagetsi, uye simba rayo remagetsi rakaderera pane iro risiri-alkali girazi fiber.Inoshandiswa kunze kwenyika kune yakasimbiswa asphalt denga zvinhu zvine yakaderera mechanical simba zvinodiwa;Yakakwirira-yakasimba girasi fiber ine imwe chiyero che zirconia, iyo ine maitiro ekukwirira kwesimba, yakaderera kuburitsa uye kudhura kwakanyanya, saka inonyanya kushandiswa muzvigadzirwa zvemauto;uyezve, yakakwira-alkali fiber ine kusashanda zvakanaka uye yakabviswa zvachose.
Fiberglass Composite
Girazi fiber inogonawo kusanganiswa nezvimwe zvinhu kugadzira girazi fiber composite zvinhu, iyo FRP ndiyo inonyanya chigadzirwa.Girazi fiber inogona kugadzirwa neresin kuita girazi fiber reinforced plastic (FRP), kana kuwedzera asphalt kugadzira girazi faibha yakasimbiswa asphalt.Nekuda kwehukuru hwakakura hwezvinhu zvinogona kuumbwa, parizvino hapana chakajeka kupatsanurwa kwegirazi fiber composite zvinhu.Zvinoenderana nedata reQianzhan Indasitiri Research Institute, FRP inosvika makumi manomwe neshanu muzana emusika wegirazi fiber composite zvinhu uye zvigadzirwa, zvichitora chinzvimbo chikuru.Naizvozvo, isu tinotora FRP semuenzaniso wekuongorora mabhenefiti ekuita kwegirazi fiber composites.
FRP ndiyo imwe nzira ine hunyanzvi hwekuita.FRP chinhu chinoumbwa chine synthetic resin sematrix uye girazi fiber uyefiberglass zvigadzirwa(mat, jira, bhandi, nezvimwewo) sechinhu chinosimbisa.FRP inowana zita rayo kubva kune yayo girazi-sekutaridzika uye simbi-kunge simbi yakasimba.Kuenzaniswa nesimbi yakajairika mukuvaka, kuwanda kwesimbi ndeye 7.85 × 103kg/m3, uye density yeFRP ndeye 1.9 × 103kg/m3, iyo yakareruka kupfuura simbi, uye yayo chaiyo simba uye ngura kuramba kunopfuura kupfuura simbi;kana zvichienzaniswa nealuminium alloy, thermal conductivity yealuminium alloy i203.5W/m.℃, uye thermal conductivity yeFRP i0.3W/m.℃.Thermal insulation performance yeFRP iri nani, uye hupenyu hwesevhisi hweFRP makore makumi mashanu, inova yakapetwa kaviri yealuminium alloy.Nekuda kwekuita kwayo kwakaringana kuita, FRP, sechinzvimbo chemidziyo yechinyakare, inoshandiswa zvakanyanya mukuvaka, njanji, aerospace, yacht berthing uye mamwe maindasitiri.
Girazi fiber indasitiri cheni
Iyo yakakwira mbishi zvinhu zvegirazi fiber zviri nyore kuwana, uye kudzika kwemvura kushandiswa kwakakura.Zvigadzirwa zvekugadzirwa kwegirazi fiber zvinonyanya kuita mineral raw materials uye kemikari mbishi zvinhu, zvinosanganisira pyrophyllite, kaolin, jecha requartz, limestone, nezvimwewo, izvo zvicherwa zvine matura makuru muChina, uye zvakaoma kuwana;simba rinoshandiswa rinonyanya magetsi uye gasi rechisikigo;pasi pemvura application Iyo yakakura, kunyanya inosanganisira zvekuvakisa, zvekufambisa, midziyo yemagetsi, zvigadzirwa zvemaindasitiri, simba uye kuchengetedza kwezvakatipoteredza uye mamwe minda.
Girazi fibrekudiwa kwemusika
Kubva pamaonero makuru, zvinotarisirwa kuti chiyero chegirasi renyika yangu faibha inoda kukura kusvika kuGDP yekukura kwehuwandu hucharamba huri hwepamusoro-soro munguva pfupi.Inofungidzirwa kuti nyika yangu girazi fiber kushandiswa mumakore 22/23 achava mamiriyoni 5.34 matani uye mamiriyoni 6 matani, kuwedzera 13.2% uye 12.5% maererano.
Tichifunga nezvekushandiswa kwakakura kwegirazi fiber, mudzimba macroeconomic zviratidzo zvichine kutungamira kukosha kwekutonga mudzimba girazi fiber kudiwa.Mukuona kwe: 1) iyo per capita yegore kushandiswa kwegirazi fiber yakaderera zvikuru kupfuura iyo yenyika dzakabudirira;2) mwero wekupinda kwegirazi fiber muminda mikuru yegirazi fiber application, senge kuvaka uye mota, yakadzikira kupfuura iyo yenyika dzakabudirira, uye sechinhu chitsva Inotungamirwa nekusimudzira mutemo, tinotenda kuti chiyero chenyika yangu. girazi fiber inoda kukura kwechiyero chekukura kweGDP icharamba iri padanho repamusoro munguva pfupi, uye inotarisirwa kuswedera padyo nemusika wakakura munguva yepakati uye kwenguva refu.
Zvinotarisirwa kuti reshiyo yegirazi renyika yangu fiber inoda kukura mwero kusvika kuGDP yekukura mwero icharamba iri padanho repamusoro munguva pfupi.Pasi pemafungiro asina kwaakarerekera, zvinofungidzirwa kuti chiyero chegirasi faibha chinoda kukura mwero kusvika kuGDP yekukura mumakore 22/23 ichave 2.4 uye 2.4 zvichiteerana, inoenderana negirazi fiber.Chiyero chekukura kwefiber chinodiwa chaive 13.2% uye 12.5% zvakateerana, uye girazi fiber kushandiswa yaive 5.34 uye 6 miriyoni matani zvichiteerana.
