Umehluko phakathi Ibhodi epoxy engama-3240 kunye nebhodi ye-fr4 epoxy

1. Izinto eziphambili ze-fr4 epoxy board zithunyelwa ngaphandle kwe-prepreg. Imibala imhlophe, tyheli kunye nohlaza. Isenamandla omatshini aphezulu kwindawo yobushushu obuyi-150℃. Inokusebenza kakuhle kombane kwindawo eyomileyo nemanzi, ibuyisa idangatye, kwaye isetyenziselwa iimveliso zombane neze-elektroniki. Iinsulation structural parts kwamanye amashishini zenziwa ngocoselelo ngemathiriyeli ekrwada ethengwa kumazwe angaphandle, oomatshini bokushicilela basekhaya kunye neenkqubo ezisemgangathweni;

Ibhodi ye-fr4 epoxy inomsebenzi ozinzileyo wokugquma umbane, ukuthambeka okuhle, umphezulu ogudileyo, akukho mingxunya, kunye nemigangatho yokunyamezela ukutyeba. Ilungele iimveliso ezineemfuno zokugquma kwe-elektroniki ezisebenza kakhulu, ezinje ngeebhodi zokuqinisa ze-FPC, iipadi zokomba ze-PCB, kunye ne-glass fiber mesons. , Potentiometer carbon film eprintiweyo iglasi fiber ibhodi, echanekileyo star gear (wafer ukucola), ipleyiti yovavanyo oluchanekileyo, izixhobo zombane (zombane) zokugquma indawo yokuhlala, ipleyiti exhasayo yokugquma, ipleyiti yokugquma isiguquli, ukugqunywa kwemoto, igiya yokusila, iswitshi ye-elektroniki yokugquma ibhodi, njl. .

2. Ibhodi epoxy engama-3240 ngokubanzi ibizwa ngokuba yi-3240 epoxy phenolic glass cloth laminate. Yenziwe ngelaphu leglasi yombane efakwe kwi-epoxy resin, yomisiwe kwaye icinezelwe kushushu. I-epoxy resins ngokubanzi ibhekisa kwiikhompawundi zepolymer eziphilayo eziqulethe amaqela amabini okanye ngaphezulu epoxy kwimolekyuli. Ngaphandle kwabambalwa, ubuninzi babo bemolekyuli abukho phezulu.

Isakhiwo se-molecular ye-epoxy resin ibonakaliswe liqela elisebenzayo le-epoxy kwi-chain chain. Iqela le-epoxy linokuthi libekwe ekupheleni, phakathi okanye kwi-cyclic structure ye-molecular chain. Inkqubo ye-epoxy resin enyangisiweyo yinto egqwesileyo yokugquma eneempawu eziphezulu ze-dielectric, ukumelana nokuvuza komphezulu, kunye nokumelana ne-arc.

Ibhodi ye-epoxy ye-3240 isetyenziswa kakhulu kwi-mechanical, electronic and electronic applications. Ilungele oomatshini, umbane, i-elektroniki, umbane kunye nezinye iinkalo. Ikwasetyenziselwa ukusetyenzwa kweendawo zokugquma kwaye zicutshungulwe kwiindawo ezahlukeneyo zokugquma. Izixhobo zokugquma iindawo zesakhiwo.
