Qhov teeb meem zoo ntawm epoxy board yog ib qho kev xav txog cov teeb meem zoo hauv ntau yam txheej txheem xws li epoxy resin, gluing, thiab nias. Txawm hais tias nias yog txheej txheem tseem ceeb kawg hauv epoxy board manufacturing, qhov zoo ntawm cov khoom semi-tiav uas tsim nyob rau hauv cov txheej txheem dhau los yuav muaj kev cuam tshuam ncaj qha rau ntawm lub rooj tsavxwm zoo.
(1) Nto pitting. Qhov tshwm sim no feem ntau tuaj yeem tshwm sim hauv daim hlau nyias, feem ntau nrog cov ntaub nplaum nplaum, tshwj xeeb tshaj yog cov khoom siv nrog cov nplaum nplaum, cov ntsiab lus tsis tshua muaj kuab lom, thiab cov khoom siv tsis zoo. Yog tias tsuas yog cov ntawv nyias nyias vim muaj cov khoom tshwj xeeb cov kev txwv, cov ntawv ncoo yuav tsum tau ua kom tuab thiab hloov ntau zaus. Lub sij hawm preheating yuav tsum tsis txhob ntev dhau, thiab lub siab yuav tsum ua raws li zoo. Tsis tas li ntawd, qhov kub ntawm lub phaj kub yuav tsum tsis txhob siab dhau thaum cov kua nplaum ntws.
(2) Qhov saum npoo tsis sib xws thiab corrugated. Qhov tshwm sim no feem ntau tshwm sim hauv daim ntawv nplaum nplaum nrog cov ntsiab lus siab resin thiab solubility tsawg. Vim qhov tsis tshua muaj dej ntawm cov resin, qhov tsis sib xws ntawm cov nplaum thaum lub sij hawm gluing yog qhov tsis sib xws thiab corrugated nto tshwm sim ntawm lub laminated board.
(3) Laminate cracking phenomenon. Nws feem ntau tshwm sim ntawm cov ntawv tuab thiab cov ntaub ntawv tuab, thiab hauv cov xwm txheej hnyav, kev tawg tshwm sim hauv laminates nrog lub thickness ntawm 5 hli lossis ntau dua. Epoxy phenolic iav ntaub board tsis yooj yim rau tawg, uas yog vim muaj zog nplaum quab yuam ntawm cov nplaum.
(4) Cov xim nyob nruab nrab ntawm qhov chaw yog tsaus. Whitening ib ncig yog vim qhov loj ntawm cov teeb meem tsis zoo nyob rau hauv daim kab xev nplaum. Thaum lub sij hawm preheating, volatile teeb meem yog ib qho yooj yim kom dim ib ncig, thiab muaj ib tug loj npaum li cas ntawm residual volatile teeb meem nyob rau hauv nruab nrab. Yog li ntawd, cov cheeb tsam ib puag ncig yog xim dawb thiab xim nruab nrab yog tsaus. Qhov no tuaj yeem txiav txim siab los ntawm qhov tsis muaj hluav taws xob tsis zoo ntawm qhov nruab nrab ntawm lub rooj tsavxwm piv rau qhov dawb ntawm ntug, uas tuaj yeem raug ntaus nqi rau cov teeb meem tsis haum.
(5) Nto fracturing. Yog hais tias cov resin yog nias sai heev thaum lub sij hawm khiav, uas yuav ua rau lub substrate puas, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj tus naj npawb ntawm lub sij hawm thiab siab ntawm daim nplaum daim kab xev thaum khiav.
6) Qhov chaw nplaum nplaum. Lub thickness sib txawv ntawm cov khoom siv ntxiv dag zog rau lub cev yog qhov loj, uas tuaj yeem ua rau cov nplaum tsis sib xws lossis tsis muaj peev xwm ntawm lub tshuab gluing, ua rau cov ntaub nplaum nplaum rau cov ntaub iav. Cov ntsiab lus nplaum ntau dhau ntawm ib txoj hauj lwm, qhov dej tsis sib xws, tsis sib xws ntawm cov phaj kub thaum lub sij hawm preheating, siab soluble resin cov ntsiab lus, thiab ceev ceev thaum resin ntws.
(7) Lub thickness sib txawv ntawm lub laminate yog loj. Qhov sib txawv thickness sib txawv yog tias ntug yog tuab thiab nruab nrab yog nyias, uas feem ntau yog tshwm sim los ntawm qhov tsis sib xws ntawm cov hlau phaj. Yog li ntawd, cov ntawv hlau yuav tsum tau ua tib zoo khaws cia, thiab yog tias muaj cov npoo pom tias muaj grooves, lawv yuav tsum flattened ua ntej siv. Kuj tseem muaj qhov tshwm sim ntawm daim nplaum nyias nyias nrog qhov sib txawv loj, uas feem ntau tshwm sim los ntawm kev laus thiab kev sib tw nplaum daim kab xev ib zaug, los yog qhov kub thiab txias ntawm ib sab ntawm lub phaj kub, nrog rau tilting ntawm kub. phaj. Yog li ntawd, thaum npaj cov ntaub ntawv, nws yuav tsum tau sau tseg thiab boil ib feem ntawm daim nplaum nplaum thiab kho nws upside down mus rau 180 degree, thiab lub inlet thiab qhov hluav taws xob ntawm lub raj yog staggered.
(8) Lub rooj tsavxwm swb tawm. Thaum nias, daim kab xev nplaum swb tawm ntawm lub phaj hlau, tshwj xeeb tshaj yog thaum nias epoxy phenolic iav ntaub board, uas feem ntau hu ua "cov ntaub ntawv to". Muaj ntau qhov laj thawj rau cov khoom xau, xws li cov nplaum nplaum ntau dhau ntawm cov nplaum nplaum, tsis sib npaug ntawm cov nplaum nplaum ntawm ob sab, kev npaj cov khoom tsis sib xws, kev thauj khoom tsis zoo, siab dhau thaum preheating thiab kua nplaum ntws, thiab lub zog tsis sib xws ntawm lub phaj kub nws tus kheej. , uas tuaj yeem ua rau cov khoom xau. Cov khoom xau tuaj yeem ua rau tus kheej thiab cov khoom sib tsoo, thiab nws yuav tsum tau ua tib zoo saib xyuas kev tiv thaiv.
