Chii chinonzi fr4 pepa rezvinyorwa?

Rudzii rwezvinhu zvemberi Ndehupi hunhu hwayo uye kushandisa?

Bheji reBrown rumwe rutivi rweEpoxy pepa, "fr" ipfupiso ye "murazvo unodzoreredza", uye bepa reFr4 ndiwo murazvo unodzora zvinhu izvo zvinosangana negwaro re "Fr4". Fr4 pepa iri kupisa uye unyoro rinodzivirira, uchisimbisa uye murazvo unodzoreredza, uye une yakanaka michina uye dielectric zvivakwa. Kupisa uye unyoro hwekupokana, kusimbisa uye kupfumisa kudzoreredza, uye kune zvakakwenenzverwa zvivakwa, zvinowanzoshandiswa mumabhodhi edunhu, zvinoshandiswa nemhando dzakasiyana siyana, kudhiraivha mapads uye kumwe kugadzirwa.

Chii chinonzi fr4 pepa?

Fr4 pepa rudzi rwechirambidzo yepepa (epoxy resin pepa), inova zvinhu zvinoumbwa zvakagadzirwa neepoxy resin, iyo organic polymer yakaenzana, uye girazi fiber. "

Kune akawanda mavara eFR4 pepa, akadai seyena, dema, girini, bhuruu uye zvichingodaro.

Ndezvipi zvinhu zveFr-4 epoxy pepa?

Sei uchiti Fr-4 ePoxy Boxy Box Production uchishandisa epoxy Boy, iri nyore kugadzirwa uye maitiro, isu tinogadzira Fr-4 ePoxy Box Boxy inogona kutemwa kuita zvakasiyana Size zvichienderana nekutenda kwevatengi, uye ine michero yakakwira uye dielectric zvivakwa: Insulation Boot Suppliers, kupisa kwakanaka uye unyoro, uye michina yakanaka.

Fr-4 EPOXEL BHUKU RINOGONESA ZVESE ZVESE ZVESE ZVESE ZVESE ZVESE ZVESE ZVESE ZVESE ZVESE ZVAKAITWA ZVAKAITWA ZVAKAITIKA CUPLETION DZIMWE DZESVONDO chimiro) uye chinogona kushandiswa mumamiriro ezvinhu epakiremera emamiriro ekunze uye kushandura mafuta.

Unhu hwakasiyana-siyana hwe epoxy board:

1.A marudzi akasiyana mafomu. Mhando dzakasiyana-siyana dzesvomhu, kurapa vamiririri, modifiers system zvakakwanisa kuenderana nezvinodiwa zvezvinhu zvakasiyana-siyana zvinyoreso zvakataurwa.

2.strong denderedzwa. Epoxy resin molecular chain inherent in the polar hydroxyl and ether bonds exist so that it has a high adhesion to various types of substances.

3.Mechanical zvivakwa. Akarapa epoxy resin system ine yakanaka michina.

4.wl lowlinkage. Epoxy resin uye maitiro ekurongedza mumiririri anoshandiswa ari kuburikidza nekuwedzera kwekuwedzera kwekuita kana epoxy resin molecule mune yekuvhenekera polymerization maitiro ekuti hapana mvura kana zvimwe zvigadzirwa zve-zvisina kujairika zvakaburitswa.

5.Electrical zvivakwa. Akaporeswa Epoxy resin system ndeye yakanaka yekuchinja zvinhu neyakanyanya dielectric zvivakwa, kuramba kune yepamusoro yekukara, arc kuramba.

6.Kunyange kuri nyore. Iko kushandiswa kwemhando dzakasiyana siyana dzekurapa kwehurongwa hwekuratidzira epoin system kunogona kurapwa mune tembiricha yekudziya ye 0-180 ℃.

7.chemical kugadzikana. General akarapwa epoxy resin system ine yakanaka alkali kuramba, acid kuramba uye solvent kuramba. Kufanana nekuporesa ipoxy system yehumwe hunhu hweimwe chete, makemikari kugadzikana kunoenderana neyekugadzirisa uye kurapa mumiririri anoshandiswa. Kushandiswa zvine mwero kwe epoxy inoisa uye kurapa vamiririri, kunogona kuita kuti ive neyakakosha makemikari kugadzikana kuita.

8. Dimensional kugadzikana. Iko kusanganiswa kwehuwandu hwezvakawanda zviri pamusoro maitiro eiyo epoxy resin system ine dimensional kugadzikana uye kusimba.

9, kupokana kunoita mold. Iyo yakarongedzwa epoxy resin system inodzivirira kune yakawanda kuumbwa uye inogona kuiswa mumamiriro ezvinhu akaoma ekupisa.

2.Application yeFR4 pepa

Bepa reFr4 rine rakawanda rakawanda rekushandisa, kunyanya rinoshandiswa mumagetsi, magetsi, kutaurirana, aerospace uye mamwe minda. Izvi zvinotevera zvinoshandiswa mainini:

1. Matunhu ematunhu

MuPepa remagetsi kugadzira, Fr4 pepa rinowanzoshandiswa mukugadzirwa kwemabhodhi edunhu. Inogona kushandiswa seyakajeka zvinyorwa zvemabhodhi edunhu kuti ive nechokwadi chekugadzikana uye kuvimbika kwemabhodhi edunhu.

2. Spacer uye kuzviparadzanisa zvinhu

Fr4 Sheet ine Superb Inosimbisa Zvivakwa uye Yakanyanya kupisa tembiricha, saka inogona kushandiswa seyakawandisa uye yekuzviparadzanisa zvinhu zviri muhurongwa hwemagetsi. Izvi hazviratidzi chete kuchengetedzwa kwemagetsi kwemidziyo, asi zvakare kudzivisa tsaona kunokonzerwa nekukanganisa kwemagetsi.

3. Mechanic zvikamu

Fr4 pepa rinogona kushandiswawo seyakagadzirwa nezvikamu zvemakwenzi, zvakadai semapuranga ekushandisa zvikwangwani uye emaindobile injini inovhara. Iyo ine yakanakisa manhamba emagetsi uye makemikari kugadzikana, uye inogona kushandiswa mune dzakasiyana mashini masisitimu.

In conclusion, FR4 sheet, as an important electrical material with excellent electrical properties, mechanical strength and chemical stability, is widely used in aerospace, communications, electronics, electrical and other fields. Zvemabhizimusi eMagetsi ekugadzira, kusarudza yakakwirira-mhando fr4 pepa rinogona kuvabatsira kuvandudza zvigadzirwa zvemhando yepamusoro uye yemusika kukwikwidza.
