Zvinhu Zvakagadziriswa Zvinobudirira Zvikuru: Girazi Fiber Yakagadziriswa Yakagadziriswa Phenolic Resin (FX-501)

Phenolic Girazi Fiber, pakati pemaresini ekutanga ekugadzira zvinhu, inowanzova polycondensate inoumbwa nekuumbwa kwephenols nealdehydes kana paine alkaline catalyst. Zvimwe zvinowedzera zvinozoiswa kuti zvibatanidze chimiro che macromolecular, zvichichichinja kuita chimiro che macromolecular chisinganyungudike uye chisinganyungudike, nokudaro chichiva chimiro chakajairika. zvinhu zvepolymer zvinogadzirisa thermosettingMaresin ephenolic anokosheswa zvikuru nekuda kwehunhu hwawo hwakanaka, kusanganisira kunonoka kwemurazvo, kugadzikana kwechimiro, uye simba rakanaka remuchina. Hunhu uhwu hwakakurudzira kutsvagurudza kwakakura uye kushandiswa kwezvinhu zvephenolic glass fiber resin.

Sezvo hupfumi hwemaindasitiri huchifambira mberi nekukurumidza, zvinodiwa zviri kuwedzera pakushanda kwe phenolic Zvinhu zveGirazi zveFibers. Nekuda kweizvozvo,magirazi e-phenolic akagadziridzwa ane simba guru uye anodzivirira kupisadziri kugadzirwa uye kushandiswa zvakanyanya. Resin yegirazi yakasimbiswa nefaibha yakagadziriswa phenolic resin (FX-501)parizvino ndeimwe yezvinhu zvakagadziriswa zvemagirazi e-phenolic fiber resin zvinobudirira zvikuru. Imhando itsva yezvinhu zvakagadziriswa uye zvakasimbiswa zve-phenolic zvakagadzirwa nekubatanidza magirazi fibers mu-resin matrix yekutanga kuburikidza nekusanganisa.

Zvivakwa zveMichina uye Mabasa eVamiririri

Phenolic girazi fiber resininowanzo sarudzwa sematrix ye zvinhu zvisingapfeki, zvinorema, uye zvinodzvinyiriranekuda kwesimba rayo rakanaka rekudhonza, kuramba zvinonyungudutsa, uye hunhu hwakanaka hwemakanika senge kunonoka kwemurazvo. zvinhu zvematrixinonyanya kushanda sechinobatanidza, ichibatanidza zvikamu zvese. Magirazi egirazidzinoshanda sezvikamu zvikuru zvinotakura mutoro muzvinhu zvisingapfeki, zvichipa kugona kwekutakura mutoro, uye kushanda kwadzo kwepamusoro kunokanganisa zvakananga simba rekusimbisa matrix.

Basa rematrix nderekubatanidza zvakasimba zvimwe zvikamu zvechinhu chinodhonza, zvichiita kuti mutoro ufambe zvakaenzana, ugovaniswe, uye ugoiswa kune magirazi akasiyana-siyana. Izvi zvinopa simba rakati uye kusimba kune chinhu chacho. Mafiber akajairika, anosanganisira magirazi, mafiber eorganic, Fiber yeSimbis, uye mineral fibers, zvinobatsira pakugadzirisa simba rekudhonza rechinhu chacho.

Kutakura Mutoro Muzvinhu Zvinosanganiswa Uye Kukanganisa Kwemukati weFiber

Mukati masisitimu ezvinhu zvakagadzirwa negirazi re phenolic fiber, zvose zviri zviviri fibers uye matrix resin zvinotakura mutoro, negirazi fibers richiramba riri iro guru rinotakura mutoro. Kana ma phenolic glass fiber composites akakomberedzwa kana kumanikidzwa, kushushikana kunotamiswa zvakaenzana kubva ku matrix resin kuenda kugirazi fibers yega yega kuburikidza ne interface, zvichinyatso paradzanisa simba rinopfuudzwa. Maitiro aya anovandudza hunhu hwemuchina wezvinhu zvakasanganiswa. Nokudaro, kuwedzera kwakakodzera mu huwandu hwegirazi fiber hunogona kuwedzera simba re phenolic girazi fiber composites.

Mhedzisiro yekuyedza inoratidza zvinotevera:

• Zvinhu zvinosanganisa girazi nefiber zvine 20% yegirazi nefiberzvinoratidza kupararira kwefaibha kusina kuenzana, dzimwe nzvimbo dzichitoshaya faibha.
• Phenolic girazi fiber composites ine 50% girazi fiber contentzvinoratidza kupararira kwefaibha kwakafanana, nzvimbo dzisina kugadzikana dzakatsemuka, uye hapana zviratidzo zvakakosha zvekubuda kwefaibha yakawanda. Izvi zvinoratidza kuti faibha dzegirazi dzinogona kutakura mutoro pamwe chete, zvichikonzera simba rakakwirira rekuchinjika.
• Kana huwandu hwegirazi fiber huri 70%, huwandu hwakawanda hwefiber hunoita kuti pave nehuwandu hwakaderera hwe matrix resin. Izvi zvinogona kukonzera zviitiko "zvisina resin" mune dzimwe nzvimbo, zvichikanganisa kutamiswa kwekushushikana uye kugadzira huwandu hwekushushikana munzvimbo. Nekuda kweizvozvo, hunhu hwese hwe phenolic glass fiber composite material inowanzo kudzikira.

Kubva pane zvakawanikwa izvi, Kuwedzerwa kwakanyanya kunobvumidzwa kwegirazi fiber mu phenolic glass fiber composites i50%.

Kuvandudza Mashandiro uye Zvinhu Zvinopesvedzera

Kubva padata renhamba, zvinhu zvakagadzirwa negirazi re phenolic fiber zvine 50% girazi fiberratidza zvinenge simba reflexural rakapetwa katatuuye simba rekudzvanya rakapetwa kana kupfuurazvichienzaniswa neresin yakachena yephenolic. Pamusoro pezvo, zvimwe zvinhu zvinopesvedzera kusimba kwemapurasitiki akasimbiswa nefekitori yegirazi yephenolic zvinosanganisira kureba kweshinda dzegiraziuye yavo kurongeka.
