Fiberglass strand mat zvinoreva jira risiri rakarukwa rakagadzirwa negirazi faibha monofilaments rakarukwa kuita network uye rinorapwa neresin binder.Iyo inorganic isiri-simbi zvinhu zvine kuita kwakanakisa., Good corrosion resistance and high mechanical simba, asi iyo yakashata ndeye brittleness uye kusapfeka kusakara.3m fiberglass mat inowanzo shandiswa sechinhu chinosimbisa muzvinhu zvinosanganiswa, magetsi ekudzivirira zvinhu uye thermal insulation materials, circuit substrates uye mamwe minda yehupfumi hwenyika.
一、 Hunhu uye kushandiswa kwegirazi fiber mat
Girazi fiber mat ine hunhu hwekupisa kupisa kwekushisa, kunaka kwekushisa kwekushisa, kukwirira kwemutsindo kunyura, kupera kwegasi kucheneswa kwemagetsi, corrosion resistance, anti-moth-eaten, anti-mildew, low absorption rate, good vibration resistance, moto. retardant, light weight zvichingodaro.
Yakakora fiberglass mat inoshandiswa zvakanyanya se fiberglass base jira, anti-corrosion, thermal insulation, fire-retardant, waterproof material, epoxy copper clad laminate uye zvigadzirwa zvemagetsi zvekudzivirira.Yakakodzera kuenderera mberi kwekushanda kwemuchina kana kuisa ruoko kugadzira akasiyana FRP zvigadzirwa (FRP), mahwendefa, pombi, matangi, matangi, yachts, hutsanana ware uye zvimwe zvigadzirwa.
E-girazi fiber inonzwa inoshandiswa kune epoxy copper clad laminates uye zvigadzirwa zvemagetsi zvekudzivirira.Alkali girazi faibha yakaonda inonzwa ndeyepamusoro-mhando zvinhu zvekuparadzanisa bhatiri, denga rekudzivirira mvura, gypsum board ekudzivirira mapaneru, pasi epurasitiki uye kemikari pombi linings ye-anti-leakage uye anti-corrosion.
二、Glass fiber mat application zvinodiwa
Kuisa ruoko-kumusoro: Kuisa-maoko ndiyo nzira huru yekugadzira FRP munyika yangu.Girazi faibha yakachekwa tambo mat, inoenderera mat uyeFiberglass Tsono Mat zvose zvinogona kushandiswa kuisa maoko-up.Iko kushandiswa kwe-stitch-bonded inonzwa kunogona kuderedza nhamba yezvikamu uye kugadzirisa kushanda kwemaoko ekuisa-up mashandiro.Zvisinei, nekuti stitchbonded felt ine shinda dzakawanda dzekemikari fiber stitchbonding, mabubbles haasi nyore kudzinga, uye zvigadzirwa zvefiberglass zvine mafuro akawanda akaita setsono, uye pamusoro pacho panoita seyakakwasharara uye isiri kutsvedzerera.Pamusoro pe,Needle Mat'skufukidzwa kwe mold ipfupi pane iyo yekucheka yanzwa uye inoramba ichinzwa.Paunenge uchigadzira zvigadzirwa zvine maumbirwo akaomarara, zviri nyore kugadzira voids pakubhenda.Iyo ruoko yekuisa-up process inoda kuti mat ive nehunhu hwekukurumidza resin infiltration rate, kubviswa kuri nyore kwemabhuru emhepo uye yakanaka mold kufukidzwa.
Pultrusion: Iyo pultrusion process ndeimwe yemashandisirwo makuru eFiberglass combo mat nemameti akasonwa.Kazhinji, inoshandiswa pamwe chete neroving isina kutenderera.Kushandisacombo mat uye zvakasonanidzwa zvinonzwika sezvigadzirwa zvakanyungudutswa zvinogona kuvandudza zvakanyanya hoop uye kuchinjika kusimba kwezvigadzirwa uye kudzivirira zvigadzirwa kubva pakutsemuka.Iyo pultrusion process inoda kuti mat ive neuniform fiber kugovera, yakakwirira kusimba simba, kukurumidza resin infiltration rate, yakanaka kuchinjika uye mold kuzadza, uye mat inofanira kuve nehumwe hurefu hunoenderera.
RTM: Resin transfer molding (RTM) ndeye yakavharwa-mold mold process.Iyo inoumbwa nehafu-molds, yevakadzi mold uye murume mold, pombi inodzvinyirira uye jekiseni pfuti, isina muchina.Iyo RTM maitiro anowanzo shandisa anoenderera mberi nemateti akasonwa panee-girazi rakachekwa tambo mat.Pepa rinonzwa rinodiwa kuti rive nehunhu hwekuti shiti rinonzwa rinofanira kunge rakazara neresin, kunaka kwemhepo kupenya, yakanaka resin scour kuramba uye yakanaka overmoldability.
Maitiro ekupeta: Kazhinji, tambo yakachekwa uye meti inoenderera inoshandiswa kupeta uye kugadzira resin-yakapfuma dhizaini inonyanya kushandiswa kune zvigadzirwa, zvinosanganisira yemukati lining layer uye yekunze.Izvo zvinodikanwa zvegirazi fiber mat mukuita mhepo inotenderera zvakangofanana neizvo zviri muruoko yekuisa-up nzira.
Centrifugal casting molding: yakachekwa tambo mat inowanzo shandiswa seyakabikwa.Iyo yakachekwa tambo mat inogadzikwa mu mold, uye ipapo resin inowedzerwa mukati inotenderera yakavhurika mold mhango, uye mabhuru emhepo anoburitswa ne centrifugation kuita kuti chigadzirwa chiwedzere.Iyo inonzwa pepa inodiwa kuti ive nehunhu hwekupinda nyore uye kunaka kwemhepo.
三、Girazi fiber mat classification
Girazi fiber mats anowanzo kupatsanurwa muzvikamu zvitatu: pamusoro pemateti, anoenderera mberi uye akachekwa tambo mats.
1.Fiberglass Surface Mat: Kazhinji, kuvandudza maitiro epamusoro uye kuderedza pesvedzero yejira patani pamusoro, inopfapfaidzwa kubva kune fiber tambo;
2. Inoramba ichinzwa: Nzira yekugadzira inopfapfaidzwa neinoenderera mberi fiber tambo;chinowanzo shandiswa sechinhu chinonatsiridza, tambo yakachekwa inonzwika ichashandiswa zvishoma muruvoko kuisa-up maitiro kuwedzera simba remukati, uye rinoshandiswa zvishoma.
3.Chopped strand mat zvinhu: Nzira yekuumba inopfapfaidzwa nekapfupi fiber tambo;
Musiyano uripo pakati pekunzwa kwepamusoro, kuenderera kunonzwa uye kuchekwa tambo inonzwa
Iyo yekumusoro inonzwa inowanzo shandiswa kunatsiridza maitiro epamusoro uye kuderedza simba rejira patani pamusoro; Musiyano uripo pakati pemata anoenderera uye akachekwa tambo mats, sekureva kunoita zita, ndeyekuti nzira yekugadzira ndeye kushandisa pfupi fiber filaments kana. continuous filaments.Inoenderera mberi inonzwa inowanzoshandiswa sechinhu chinoshandiswa, uye tambo yakachekwa inonzwa inoshandiswa zvishoma mukugadzirisa ruoko kuisa-up kuti iwedzere simba re interlayer uye rinoshandiswa zvishoma.
