Laminating txheej txheem ntawm mica board ua

Cov txheej txheem lamination ntawm mica board yog txheej txheem tseem ceeb hauv lamination molding. Cov txheej txheem lamination yog kom phim cov ntaub nplaum impregnated rau hauv ib lub slab raws li qhov xav tau ntawm cov thickness, muab tso rau hauv polished hlau template, thiab muab tso rau ntawm kub xovxwm kom sov, nias, solidify thiab txias ob txheej ntawm templates. , Demoulding, post-processing, thiab lwm yam.

1. Daim kab xev txiav. Cov txheej txheem no yog txiav daim kab xev rau ib qho loj 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 tau ua kom raug. Muab cov kab xev txiav kom huv si, 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. Cov ntaub nplaum sib txuam. 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 dhau. Yog hais tias cov ntsiab lus volatile loj heev, nws yuav tsum tau qhuav ua ntej siv.

3. Kub nias txheej txheem. 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 qhov kub, siab thiab lub sijhawm. Kev kov yeej lub vapor siab ntawm cov volatiles, ua rau cov khoom sib txuas ua ke, thiab ua rau cov ntaub nplaum nplaum sib txuas; 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.Post-processing. 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.
