Corrugated boards feem ntau muab faib ua ntau txoj hauv kev raws li qhov chaw thov, board yoj qhov siab, ncej puab, thiab cov khoom siv.
Cov txheej txheem kev faib ua feem ntau yog raws li hauv qab no:
(1) Raws li kev faib tawm ntawm cov khoom siv, nws tau muab faib ua lub ru tsev panels, phab ntsa panels, pem teb decks thiab qab nthab panels. Hauv kev siv, cov xim hlau phaj yog siv los ua cov phab ntsa kho kom zoo nkauj tib lub sijhawm, thiab cov nyhuv kho kom zoo nkauj architectural yog qhov tshiab thiab tshwj xeeb.
(2) Raws li kev faib tawm yoj qhov siab, nws muab faib ua lub siab yoj phaj (yoj qhov siab ≥70mm), nruab nrab yoj phaj thiab qis yoj phaj (yoj qhov siab <30mm)
(3) Kev faib tawm los ntawm cov khoom siv substrate - muab faib ua kub-dip galvanized substrate, kub-dip galvanized aluminium substrate, thiab kub-dip galvanized aluminium substrate.
(4) Raws li cov qauv ntawm lub rooj tsavxwm seam, nws muab faib ua ncej puab, undercut thiab tuav cov qauv, thiab lwm yam. Ntawm lawv, lub undercut thiab crimped nruab nrab thiab siab yoj boards yuav tsum tau siv raws li lub ru tsev panels nrog siab waterproof: lapped nruab nrab thiab siab nthwv dej galvanized los xij yog siv los npog hauv pem teb; cov lapped low wave boards yog siv los ua phab ntsa panels.
