Faibha yegirazi (Girazi reFiberglass) chinhu chisina simbi chinoshanda zvakanyanya, chakagadzirwa negirazi rakanyungudutswa, chine huremu hwakareruka, simba guru, chinodzivirira ngura, chinodzivirira kupisa uye humwe hunhu hwakanaka. Dhayamita yemonofilament yayo idiki ma microns kusvika anopfuura makumi maviri ma microns, yakaenzana ne1/20-1/5 yebvudzi, uye bundle rega rega refaibha isina kubikwa rinoumbwa nemazana kana kunyange zviuru zve monofilaments.
Yakavakirwa pa chlorite, jecha re quartz, limestone, dolomite, boron calcium stone, boron magnesium stone nezvimwe zvicherwa sezvinhu zvakagadzirwa nekunyunguduka kwekupisa kwakanyanya, kukweva, kumonerera, kuruka uye mamwe maitiro mujira, ibasa rakanaka kwazvo rezvinhu zvisiri zvesimbi zvisingasanganisike, zvakanakira zvakawanda zvekuputira zvakanaka, kuramba kupisa, kuramba ngura, simba remakanika rakawanda, asi kushaya simba kwehunhu hwe brittle, kuramba kupfeka kwakaderera. Kazhinji muchimiro che monofilament,shinda, jira, kunzwa nezvimwewo.
01, maitiro ekugadzira girazi fiber
1. Kugadzira zvinhu zvisina kugadzirwa: sanganisa jecha re quartz, limestone nezvimwe zvinhu zvisina kugadzirwa zvichienderana nehukuru hwaro.
2. Kunyunguduka kwemvura pakupisa kwakanyanya: kunyunguduka mugirazi pakupisa kwakanyanya kupfuura 1500℃.
3. Kudhirowa nekugadzira: kudhirowa nekumhanya kukuru kuburikidza neplate yekudonha kweplatinum-rhodium alloy kuti igadzire fiber inoenderera mberi.
4. Kurapa pamusoro: yakafukidzwa nechinhu chinonyorovesa kuti faibha igone kuchinjika uye kubatana kwayo neresin.
5. Kugadziriswa mushure mekugadzira: kugadzirwa kuita shinda, jira,kunzwanezvimwe zvigadzirwa zvinoenderana nekushandisa.
02, Hunhu hwegirazi faibha
Simba guru: simba rekudhonza rakakwirira kupfuura simbi yakajairika, asi huwandu hwayo ihafu yechina yesimbi.
Kuramba ngura: kuramba ngura zvakanaka kunokonzerwa neacid, alkali, munyu nemamwe makemikari.
Kudzivirira: kusafambisa mafambiro emhepo, kusafambisa mafambiro emhepo, chinhu chakanaka kwazvo chinodzivirira mafambiro emhepo.
Huremu: hushoma, hwakakodzera kushandiswa huremu.
Kudzivirira kupisa kwakanyanya: kunogona kushandiswa kwenguva yakareba pakati pe -60℃ kusvika 450℃.
03. Minda mikuru yekushandisa yegirazi faibha
1. Munda wekuvaka
Bhawa reGFRP: imwe nzira yesimbi panzvimbo pesimbi yenzvimbo dzinoparadza dzakadai semainjiniya egungwa uye mafekitori emakemikari.
Zvinhu zvekudzivirira madziro ekunze: zvakareruka, hazvitsvi uye zvinodzivirira kupisa.
Kusimbiswa kwekongiri: kuvandudza kuramba kusingatsemuke uye kugara kwenguva refu.
2. Kutakurwa
Zvishoma zvemotokari: zvinoshandiswa mumapaneru emuviri, mabumpers, chassis nezvimwe zvikamu.
Kutakurwa kwechitima: kunoshandiswa mungoro dzechitima dzinomhanya zvikuru, mukati mechitima chepasi pevhu, nezvimwewo.
Mudenga: inoshandiswa pakugadzira mafairingi endege, ma radomes, nezvimwewo.
3. Simba idzva
Mapazi emhepo: anoshandiswa sezvinhu zvinosimbisa simba remapazi uye kushanda zvakanaka kwekuneta.
Zvigadziko zve photovoltaic: hazvipindi ngura, zvakareruka, uye zvinogara kwenguva refu.
4. Zvemagetsi nemagetsi
Chigadziko chebhodhi redunhu: chinoshandiswa pabhodhi rakaputirwa nemhangura reFR-4.
Zvinhu zvinodzivirira kupisa: Zvinoshandiswa pakudzivirira kupisa kwemota, transformer nezvimwe zvishandiso.
5. Nzvimbo yekudzivirira zvakatipoteredza
Zvinhu zvekusefa: zvinoshandiswa pakusefa gasi rinopisa zvakanyanya, kurapwa kwemvura, nezvimwewo.
Kurapa tsvina: kunoshandiswa kugadzira matangi nemapombi anodzivirira ngura.
04, mafambiro ekuvandudza girazi remagirazi mune ramangwana
1. Kushanda kwepamusoro: kugadzira girazi fiber rine simba rakawanda uye modulus.
2. Kugadzira zvinhu zvisina tsvina: kuderedza kushandiswa kwesimba rekugadzira uye kusvibiswa kwezvakatipoteredza.
3. Mashandisirwo ehungwaru: akasanganiswa nemasensa ezviumbwa zvine hungwaru.
4. Kubatanidzwa kwemiganhu: kusanganiswa nekabhoni faibha, faibha yearamid, nezvimwewo, kuwedzera nzvimbo yekushandisa.
