Fiberglass imhando yeinorganic isiri-metallic zvinhu zvine mashandiro akanaka.Iine mabhenefiti akasiyana-siyana, akadai sekudzivirira kwakanaka, kupisa kwakasimba kwekudzivirira, kunaka kwekusagadzikana uye kusimba kwemagetsi epamusoro, asi zvisungo zvaro brittle uye kusapfeka kusakara.Yakagadzirwa nepyrophyllite, jecha requartz, limestone, dolomite, boehmite uye boehmite nekunyunguduka kwepamusoro-tembiricha, kudhirowa kwewaya, kuputika kweshinda, kuruka machira uye mamwe maitiro.Iyo dhayamita yemonofilament yayo inoverengeka mamicrons kune anopfuura 20 microns, yakaenzana ne1/20-1/5 yebvudzi.Imwe neimwe bundle ye fiber precursor inoumbwa nemazana kana kunyange zviuru zve monofilaments.Girazi faibha rinowanzo shandiswa sezvinhu zvekusimbisa muzvinhu zvinoumbwa, zvemagetsi zvekudzivirira zvemagetsi, zvinopisa zvekupisa, mabhodhi edunhu uye mamwe minda yehupfumi hwenyika.
Musi waGumiguru 27, 2017, rondedzero yecarcinogens yakaburitswa neInternational Agency for Research on Cancer yeWorld Health Organisation yakatanga kuunganidzwa kuti itariswe.Fibers ezvinangwa zvakakosha, senge E girazi uye "475 ″ girazi faibha, akaverengerwa mune rondedzero yeChikamu 2B carcinogens, uye inoenderera girazi fibers yakaverengerwa murondedzero yeChikamu 3 carcinogens.
Zvinoenderana nechimiro uye kureba, girazi fiber inogona kukamurwa kuita fiber inoenderera, yakatarwa urefu fiber uye girazi mvere;Zvinoenderana nekuumbwa kwegirazi, inogona kupatsanurwa kuita alkali isina, makemikari inodzivirira, yakakwira alkali, yepakati alkali, simba repamusoro, yakakwira elastic modulus uye alkali inodzivirira (alkali inodzivirira) girazi fibers.
Iyo huru yezvigadzirwa zvekugadzirwa kwegirazi fiber ndeye: jecha requartz, alumina uye pyrophyllite, limestone, dolomite, boric acid, soda ash, mirabilite, fluorite, etc. Nzira dzekugadzira dzinogona kukamurwa kuita zvikamu zviviri: imwe ndeyekugadzira zvakananga. girazi rakanyungudutswa kuita fiber;Imwe ndeyekuita girazi rakanyungudutswa mubhokisi regirazi kana tsvimbo ine dhayamita ye20mm, uye wozopisa uye uigadzirise nenzira dzakasiyana-siyana kuti iite bhora regirazi kana tsvimbo ine dhayamita ye 3-80 μ M ye fiber yakanaka kwazvo. .Iyo isingaperi faibha refu inodhonzwa nemakanika yekudhirowa nzira kuburikidza neplatinamu alloy plate inonzi inoenderera girazi fiber, iyo inowanzonzi refu fiber.Iyo discontinuous fiber inogadzirwa ne roller kana kuyerera kwemhepo inonzi fixed length glass fiber, kana kuti short fiber.
Girazi fiber inogona kukamurwa kuita mamakisi akasiyana zvichienderana nekuumbwa kwayo, hunhu uye kushandiswa.Zvinoenderana neyakajairwa nhanho, Kirasi E girazi fiber ndiyo inonyanya kushandiswa magetsi insulating zvinhu;Kirasi S ndeye faibha yakakosha.
Iyo data inoratidza kuti kusangana kweChina yegirazi fiber indasitiri yakakwira zvakazara, Jushi achiverengera 34%, ichiteverwa neTaishan Glass Fiber neChongqing International accounting ye17% zvakateerana.Shandong Fiberglass, Sichuan Weibo, Jiangsu Changhai, Chongqing Sanlei, Henan Guangyuan uye Xingtai Jinniu vakaverengera chikamu chidiki, zvichiteerana 9%, 4%, 3%, 2%, 2% uye 1%.
Kune maviri maitiro ekugadzira egirazi fiber: kaviri kugadzira crucible waya yekudhirowa nzira uye kamwe kugadzira tangi choto chevira waya yekudhirowa nzira.
Iyo crucible waya yekudhirowa maitiro ine akawanda maitiro.Kutanga, magirazi egirazi zvinhu zvakanyungudutswa mumabhora egirazi pakupisa kwakanyanya, ipapo mabhora egirazi anonyungudutswa zvakare, uye iyo yakakwirira-yekumhanya waya yekudhirowa inogadzirwa mugirazi fiber tambo.Iyi nzira ine zvakawanda zvisingabatsiri, zvakadai sekushandiswa kwesimba rakawanda, kusagadzikana kwekuumbwa kwemaitiro uye kuderera kwebasa rekushanda, uye inobviswa zvakanyanya nevagadziri vegirazi guru.
Iyo tangi yevira wiredrawing nzira inoshandiswa kunyungudutsa pyrophyllite uye zvimwe zvigadzirwa mugirazi mhinduro muchoto.Mushure mekunge mabhuru abviswa, anotakurwa kuenda kune porous drain plate kuburikidza nemugero uye anodhonzwa mugirazi fiber precursor nekumhanya kukuru.Iyo kini inogona kubatanidza mazana emapureti anovuza kuburikidza nematanho akawanda ekugadzira panguva imwe chete.Iyi nzira iri nyore mukuita, kuchengetedza simba uye kuderedza kushandiswa, yakagadzikana mukugadzira, inoshanda uye yakakwira-goho, iyo yakanakira yakakura-yakazara-otomatiki kugadzirwa uye yave iyo yepasi rose nzira yekugadzira.Girazi fiber inogadzirwa nemaitiro aya inodarika makumi mapfumbamwe muzana epasi rose.
Zvinoenderana neAnalysis Report paStatus Quo uye Tarisiro yeKuvandudza Musika weFiberglass kubva muna 2022 kusvika 2026 yakaburitswa naHangzhou Zhongjing Zhisheng Market Research Co., Ltd., pahwaro hwekuenderera mberi kupararira kweCCIDID-19 uye kuenderera mberi nekuderera mamiriro ekutengeserana epasi rese, iyo girazi faibha uye zvigadzirwa indasitiri inogona kuwana mhedzisiro yakanaka kudaro, kune rumwe rutivi, nekuda kwekubudirira kukuru kweChina mukudzivirira nekudzora denda reCCIDID-19, uye kutangwa panguva kwayo kwemusika wekuda wepamba, On. kune rimwe divi, nekuda kwekuenderera mberi kwekuita kwegirazi fiber shinda yekugadzira kugona muindastiri, kune mashoma mapurojekiti matsva uye akanonoka.Mitsetse iripo yekugadzira yakatanga kutonhora kugadzirisa panguva uye kunonoka kugadzira.Nekukurumidza kukura kwekudiwa mumaindasitiri epasi uye simba remhepo nezvimwe zvikamu zvemusika, marudzi akasiyana eshinda yegirazi fiber uye zvigadzirwa zvakagadzirwa zvakawana kukwira kwakawanda kwemitengo kubva pachikamu chechitatu, uye mitengo yezvimwe zvigadzirwa zvegirazi fiber yasvika. kana padhuze nedanho rakanakisa munhoroondo, Iyo yakazara purofiti level yeindasitiri yavandudza zvakanyanya.
Girazi fiber yakagadzirwa muna 1938 nekambani yeAmerica;Munguva yeHondo Yenyika Yechipiri muma1940, magirazi fiber reinforced composites akatanga kushandiswa muindasitiri yemauto (matangi ematangi, kabhini yendege, mabhomba ezvombo, mabhati asingapindi mabara, nezvimwewo);Gare gare, nekuenderera mberi kwekuvandudza kwekuita kwezvinhu, kudzikira kwemutengo wekugadzira uye kuvandudzwa kweyepasi pemvura inoumbwa tekinoroji, kushandiswa kwegirazi fiber kwakawedzerwa kumunda wevanhu.Zvishandiso zvaro zvepasi pemvura zvinofukidza minda yezvivakwa, njanji yekufambisa, petrochemical, kugadzira mota, aerospace, kugadzirwa kwemagetsi emhepo, midziyo yemagetsi, engineering yezvakatipoteredza, mainjiniya emugungwa, nezvimwewo, ichiva chizvarwa chitsva chezvinhu zvinoumbwa kutsiva zvechinyakare zvinhu sesimbi, huni, dombo, zvichingodaro, Inyanzvi yenyika iri kusimukira indasitiri, ine kukosha kukuru mukusimudzira hupfumi hwenyika, shanduko nekusimudzira.
