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

Nekukura nekukurumidza mumunda wemapurasitiki akasimbiswa negirazi,zvinhu zvakagadzirwa ne phenolic resindzave dzichishandiswa zvakanyanya mumaindasitiri akasiyana-siyana. Izvi zvinokonzerwa nehunhu hwadzo hwakasiyana, simba radzo remuchina, uye mashandiro adzo akanaka kwazvo. Chimwe chezvinhu zvinonyanya kukosha ndechezvinhu zve phenolic girazi fiber resin.

Phenolic girazi faibha, 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 kwezvinhu zvemagirazi ephenolic fiber. 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.

Phenolic girazi fiber resininowanzo sarudzwa sematrix yezvinhu 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 zvisingatsvedzeri, zvichipa kugona kutakura 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 zvinoita kuti chinhu chacho chive nesimba uye kusimba. Mafiber akajairika, anosanganisira magirazi, mafiber eorganic, mafiber esimbi, uye mafiber emaminerari, anoita basa rekugadzirisa simba rekudhonza rechinhu chacho.

 Kutakura Mutoro Muzvinhu Zvinosanganiswa Uye Kukanganisa Kwemukati weFiber

In zvinhu zvinoumba girazi re phenolic fibermasisitimu, zvose zviri zvivirifibers 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 muhuwandu hwegirazi fiber hunogona kuwedzera simba re phenolic girazi fiber composites.

Mhedzisiro yekuyedza inoratidza zvinotevera:

• Phenolic girazi fiber composites ine 20% girazi fiber contentzvinoratidza 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, zvichikonzerasimba rakakwirira rekuchinjika.
• Kana huwandu hwegirazi fiber huri 70%, huwandu hwakawanda hwefiber hunoita kuti pave nehuwandu hushoma 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 materialinowanzo kudzikira.

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