Taw qhia rau lamination ntawm tus kheej lubricating board mica board
1. Daim kab xev txiav: Cov txheej txheem yog txiav daim kab xev rau ib qho me me. Cov cuab yeej txiav tuaj yeem yog qhov txuas txuas ntxiv-ntev-ntev, lossis nws tuaj yeem txiav los ntawm tes. Rau daim kab xev txiav, qhov loj me yuav tsum yog qhov tseeb. Muab cov kab xev txiav kom zoo, muab cov kab xev sib txawv nrog cov kua nplaum sib txawv thiab cov dej ntws sib cais, thiab sau thiab khaws cia rau tom qab siv.
2. Kev xaiv cov ntaub nplaum: Cov txheej txheem ntawm cov ntaub nplaum xaiv 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 ntawv nplaum nrog 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 dhau. Yog hais tias cov ntsiab lus volatile loj heev, nws yuav tsum tau qhuav ua ntej siv.
3. Cov txheej txheem kub kub: Cov txheej txheem tseem ceeb tshaj plaws hauv cov txheej txheem nias yog cov txheej txheem tsis ua haujlwm, cov txheej txheem tseem ceeb tshaj plaws yog 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 sib txuas; tiv thaiv lub phaj kom tsis txhob deformed thaum nws txias. Qhov loj ntawm molding siab yog txiav txim siab raws li tus yam ntxwv curing ntawm cov resin. Feem ntau cov epoxy / phenolic laminate yog 5.9MPa, thiab cov ntawv epoxy yog 3.9-5.9MPa.
4. Kev kho tom qab: Lub hom phiaj ntawm kev kho tom qab yog txhawm rau kho cov resin ntxiv kom txog thaum nws kho tau tag nrho, thaum ib nrab tshem tawm cov kev ntxhov siab sab hauv ntawm cov khoom thiab txhim kho kev sib txuas 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.
