Coj koj kom nkag siab txog cov txheej txheem tsim khoom ntawm epoxy iav ntaub board

Kev tsim cov txheej txheem ntawm epoxy iav ntaub board:

(1) Daim kab xev raug txiav tawm. Cov txheej txheem yog txiav cov kab xev rau hauv ib qho me me, thiab cov cuab yeej txiav tuaj yeem ua ib qho txuas ntxiv-ntev-ntev slicer, lossis nws tuaj yeem txiav los ntawm tes. Daim kab xev txiav yuav tsum yog qhov loj me, 3240 epoxy board nqe, pawg txiav daim kab xev kom zoo, 3240 epoxy board manufacturers, pawg cov kab xev nrog cov kua nplaum sib txawv thiab fluidity nyias, ua cov ntaub ntawv thiab khaws cia rau yav tom ntej siv.

(2) Adhesive daim ntaub yog xaiv tau. Cov txheej txheem xaiv ntawm cov nplaum nplaum yog qhov tseem ceeb heev rau qhov zoo ntawm laminate. Yog tias qhov kev xaiv tsis raug, lub laminate yuav tawg thiab qhov chaw tawg thiab lwm yam tsis xws luag yuav tshwm sim. Nyob rau saum npoo ntawm lub rooj tsavxwm xaiv, 2 daim kab xev nplaum uas muaj cov nplaum nplaum nplaum thiab cov kua nplaum siab yuav tsum muab tso rau ntawm txhua sab. Cov ntsiab lus volatile yuav tsum tsis txhob loj heev. Yog hais tias cov ntsiab lus volatile loj heev, nws yuav tsum tau qhuav ua ntej siv.

(3) Kub nias txheej txheem. Tus yuam sij rau cov txheej txheem nias yog cov txheej txheem tsis, cov txheej txheem tsis yog qhov kub, siab thiab lub sijhawm. kov yeej lub vapor siab ntawm volatiles, ua rau cov khoom sib txuas ua ke, thiab ua rau cov nplaum nplaum nyob ze; tiv thaiv lub phaj kom tsis txhob deformed thaum nws txias. Qhov loj ntawm molding siab yog txiav txim raws li tus yam ntxwv kho ntawm cov resin. Feem ntau cov epoxy / phenolic laminate yog 5.9MPa, thiab cov ntawv epoxy yog 3.9-5.9MPa.

(4) Tom qab ua tiav. Lub hom phiaj ntawm kev kho tom qab yog txhawm rau kho cov resin ntxiv kom txog thaum nws kho tau tag nrho, tib lub sij hawm ib nrab tshem tawm cov kev ntxhov siab sab hauv ntawm cov khoom, thiab txhim kho kev sib raug zoo ntawm cov khoom. Tom qab kev kho mob ntawm epoxy board thiab epoxy / phenolic board yog khaws cia ntawm qhov kub ntawm 130-150 ℃ li ntawm 150 min.
