Hais txog kev qhia txog kev siv laminated board nplaum
Polyboard nplaum yog tus neeg sawv cev sib txuas siv rau kev sib koom ua ke cov khoom siv ntoo, tsim rau kev sib koom ua ke laminated boards hauv kev siv tsis yog cov qauv thiab cov qauv.
Lub ntsiab tivthaiv ntawm Polyboard nplaum yog ib qho tshwj xeeb uas tsim los ntawm polyvinyl acetate emulsion nrog cov khoom siv dej tsis zoo, thaum tus neeg sawv cev kho feem ntau yog isocyanate. Cov nplaum nplaum tseem ceeb yog cov kua qaub-dawb, thiab cov tshuaj tua kab mob yog lub teeb xim av. Lub ntsiab nplaum tseem tuaj yeem siv nws tus kheej ua tus ntiv tes sib koom ua ke.
Polyboard nplaum, alkaline nyob rau hauv cov xwm, yuav tsum tsis txhob nyob rau hauv ntev kev sib cuag nrog daim tawv nqaij. Thaum ntsib qhov muag, yaug tam sim nrog dej ntau thiab nrhiav kev kho mob. Nws yog tshuaj lom thiab yuav tsum tsis txhob noj, ua rau muaj kev phom sij rau kev noj qab haus huv.
Hauv kev lag luam woodworking machinery, kev siv Polyboard nplaum yog qhov tseem ceeb. Kev xaiv thiab siv cov khoom kom raug tuaj yeem hloov kho ntoo rau hauv cov txheej txheem tej yam yees siv. Nov yog qee qhov yuav tsum xav txog thaum siv Polyboard nplaum:
Ib qho kev nthuav dav ntawm Polyboard nplaum cov khoom yog kub. Ntsuas qhov kub thiab txias ntawm cov ntoo saum npoo kom raug. Qhov kub thiab txias ua lub luag haujlwm hauv kev txiav txim siab qhov nrawm ntawm qhov sib txuas ntawm cov tshuaj tiv thaiv kab mob. Ntawm qhov kub sib txawv, lub sij hawm muaj rau plywood bonding txawv; Nws feem ntau yog nyob rau hauv 30 feeb ntawm kev sib tov, tab sis nyob rau hauv txias txias thaum lub caij ntuj no, nws yuav ntev mus rau 60 feeb.
Lwm qhov kev nthuav dav yuav tsum xav txog yog cov dej noo ntawm cov ntoo. Tom qab ziab, lub substrate yuav tsum tau rov qab noo noo, thiab cov ntsiab lus noo noo yuav tsum tau tswj ntawm 7% thiab 12%. Hauv qab 7%, kev nkag mus ntau dhau thiab cov kua nplaum tsis txaus ntawm qhov sib txuas yuav tshwm sim, ua rau substrate tawg. Hloov pauv, cov dej noo ntau dhau tuaj yeem ua rau ua pa tsis zoo, tiv thaiv kev tsim cov kua nplaum rau ntawm tes thiab ua rau tsis tiav kev sib txuas sib txuas, ua rau delamination.
Thaum kawg, kev saib xyuas yuav tsum tau them rau qhov xwm txheej ntawm lub substrate nws tus kheej. Lub substrate yuav tsum tsis txhob ua qhov tsis xws luag xws li "lub taub hau gnawing" los yog "tail tom," thiab lub substrate yuav tsum muaj squareness zoo uas tsis muaj "plating marks," "pom cov cim," los yog "carbonization" nyob rau hauv daim ntawv cog lus. Nws yog nruj me ntsis txwv tsis pub kom muaj txiaj ntsig zoo ntawm cov substrates uas tau kis los ntawm cov roj, plua plav, lossis lwm yam kuab paug rau ntawm qhov chaw sib txuas.
