Cov Khoom Siv Tsevneeg Ntawm FRP Sandwich Panels

Cov khoom siv saum npoo yog xaiv raws li qhov xav tau ntawm cov khoom. Fiberboard feem ntau yog siv rau phab ntsa panels, ru tsev ntoo thiab nplooj qhov rooj ntawm cov tsev txawb; plywood lossis veneer feem ntau yog siv rau cov rooj tog txaj txee. Thaum cov khoom siv saum npoo thiab cov khoom siv tseem ceeb yog cov xim txuas, lub hauv paus feem ntau muab tso rau hauv tus ncej ntoo, tuab ntawm ntoo thav duab zoo ib yam li cov tuab ntawm cov khoom tseem ceeb, thiab cov khoom siv sab saud thiab qis dua yog them nrog glued. saum npoo board. Cov kua nplaum hom siv nyob ntawm cov khoom siv saum npoo av. Yog tias txheej saum npoo yog cov khoom ntoo, txawm yog kua nplaum urea-formaldehyde lossis kua nplaum phenol-formaldehyde tuaj yeem siv tau. Tom qab ntawd kub xovxwm, lub zog siv yuav tsum tsis txhob siab dhau, txwv tsis pub, cov khoom siv tseem ceeb yuav muab zaws thiab deformed lossis tso tawm rau ntawm lub veneer, feem ntau yog 0.2 txog 0.3 MPa. Qhov glued honeycomb vaj huam sib luag tiav lawm tom qab ua tiav, ua phiaj xwm, perforated ntawm ntug (ua pa) thiab kho saum npoo.
