一、 Ndeapi akajairika girazi fiber mafomu, unoziva?
Parizvino, fiber yegirazi inoshandiswa zvakanyanya.Girazi fiber inotora mafomu akasiyana zvichienderana neyakasiyana zvigadzirwa, maitiro uye kuita zvinodiwa zvekushandisa, kuitira kuti isangane nezvinodiwa zvekushandisa zvakasiyana.Ndeapi marudzi akasiyana-siyana akajairikafiberglass composite?
1. Twistless Roving
Kurovha kusingapindiki kunokamurwazve kuitazvakanangagirazi fiber roving zvinhu uye plied isina kumonyoroka ichifamba.Yakananga shinda ndeye inoenderera faibha inodhonzwa kubva kugirazi kunyungudika, inozivikanwawo se single-strand untwisted roving.Iyo plied yarn ijecha rakakoshwa rakagadzirwa neakawanda tambo dzakafanana, inongori masanganiswa etambo dzakawanda dzeshinda dzakananga.
Dzidzisai hunyengeri hudiki, nzira yekukurumidza kusiyanisa pakati peshinda yakananga uye plied yarn?Rudzi rumwe runodhonzwa uye runozunguzika nokukurumidza.Iyo yasara ishinda yakati twasa, uye iyo inoparadzirwa kuita tambo dzakawanda ishinda yakapfava.
2. Huru yeshinda
Shinda yakakanyiwa inogadzirwa nekukanganisa uye kuvhiringa magirazi fiber nemhepo yakamanikidzwa kuparadzanisa fiber mufilament glass fiber uye wedzera vhoriyamu, kuitira kuti ive nezvose zvakakwirira simba rekuenderera mberi fiber uye bulkiness yefiberglass yakachekwa.
3. Plaid
Plaid ndiyefiberglass weave jira.Iyo warp uye weft inopindirana pa90 ° kumusoro uye pasi, inozivikanwawo semucheka wakarukwa.Simba re gingham rinonyanya mu warp uye weft nzira.
4. Multiaxial Fabric
Fiberglass Multiaxial Fabric inogadzirwa nekuruka girazi faibha zvakananga pasina kumonyoroka roving pamushini we-axial braiding muchina.
Makona akajairika ndeye 0 °, 90 °, 45 °, -45 °, ayo akakamurwa kuita unidirectional jira, biaxial jira, triaxial jira uye quadriaxial jira zvichienderana nenhamba yezvikamu.
5. Girazi fiber mat
Gfiber matt inounganidzwa pamwe chete se "kunzwa", chigadzirwa-chakafanana neshizha chakagadzirwa netambo dzinoenderera kana tambo dzakachekwa dzisina kutungamirwa nemakemikari anosunga kana mechanical chiito.Felts zvakare yakakamurwa kuitamachira akachekwa, mashizha akasonanidzwa, mapeti akaumbwa, anoenderera mberi, mazamu epamusoro, etc. Main applications: pultrusion, winding, molding, RTM, vacuum sumo, GMT, nezvimwewo.
6.Ar girazi faibha akachekwa tambo
Fiberglass warn inochekwa kuita tambo dzehurefu hwakati.Mashandisirwo makuru: akanyorova akachekwa (yakasimbiswa gypsum, yakanyorova yakaonda inonzwa), BMC, nezvimwe.
二, ndezvipi zvinhu zvinokanganisa simba rekusimba regirazi fiber
Kubuda kweiyo inoyangarara girazi tekinoroji inogona kunzi inopa yakasimba tekinoroji rutsigiro rwegirazi yakadzika kugadzirisa, uye pasi pekutungamirirwa kweiyi inobuda tekinoroji level, mhando dzegirazi dzakadzika kugadzirisa dzave kuwanda, pakati pawo.girazi fiber epoxy compositendeyemagirazi akawanda akadzika kugadzirisa.Imwe yezvikamu, uye girazi fiber yakashandiswa zvakanyanya mumaindasitiri mazhinji neminda munharaunda yemazuva ano kubva pakutsvagisa kwayo nekusimudzira.Saka ndezvipi zvinhu zvinokanganisa kusimba kwegirazi fiber ine basa rakanaka uye simba?
Chinhu chekutanga, dhayamita yefiber uye tembiricha mamiriro enzvimbo iyo inoshandiswa.
Panyaya yechitarisiko, faibha yegirazi hairatidzike kunge yakasiyana zvakanyanya kubva kune yakajairwa shinda yesirika, asi mashandisirwo emhando yegirazi fiber yakakura kupfuura iyo yeshinda yesirika.Kunyangwe zvakadaro, simba rekusimba richava nemhedzisiro pakushandiswa kwekushandisa uye hupenyu hwesevhisi hwechinhu ichi.zvinofurira.Nekudaro, pane zvakawanda zvinhu zvinokanganisa kusimba kwekusimba kwegirazi fibers, kusanganisira dhayamita yefiber pachayo uye tembiricha yenzvimbo iyo zvinhu zvichashandiswa gare gare.Kazhinji, iyo yakaonda iyo fiber dhayamita iri pane yakapihwa tembiricha.Iyo yakakwirira simba rekusimba.
Chinhu chechipiri, kurapwa kwepamusoro kunoshandiswa
Girazi faibha inogadzirwa nekushandisa girazi sechinhu chakabikwa chekugadzirisa zvakadzika, uye nzira dzakakosha dzinodiwa mukuita kwese kwekugadzira kuti uone shanduko kubva pagirazi kuenda kune fiber.Pakati pavo, nzira dzekurapa makemikari uye nzira dzekufambisa ndedzepamusoro nzira dzekurapa.imwe ye.Kana iyo makemikari nzira yekurapa ikashandiswa panguva yekugadzirwa, simba rekusimba rinodzikira mushure mekunge saizi yabviswa nekurapa kwekupisa, asi simba rekusimba refiberglass insulation zvinhuichadzokera kune yakajairika mamiriro mushure mekunamatira kushandiswa pakati.
Izvo zviri pamusoro apa ndeyekuongorora kwezvinhu zvinokanganisa simba rekusimba regirazi fiber.Zvinogona kuoneka kuti dhayamita yefiber pachayo uye tembiricha yeiyo gare gare kushandiswa nharaunda ichakanganisa kusimba kwesimba regirazi fiber nebasa rakanaka uye mutengo wakaderera.Uye zvakare, iyo yekunze nzira yekurapa nzira inoshandiswa negirazi fiber ichakanganisawo kusimba kwayo.
