Plywood Ntau Lawm Txheej Txheem Ntsuas

Plywood, tus txiv neej tseem ceeb -}}}} siv nyob rau hauv rooj tog vaj tse, kho kom zoo nkauj, thiab ntim. Nws cov txheej txheem ntau lawm tau ua tiav dhau sijhawm, ua rau muaj kev sib txawv thiab cov khoom siv tsim tau zoo. Tus txheej txheem no feem ntau suav nrog cov kauj ruam tseem ceeb xws li cov khoom siv khoom siv, veneer npaj, gluing thiab sib dhos, thiab tshaj tawm {{3} {{kev ua.

Cov khoom lag luam raw yog qhov tseem ceeb ntxiv rau hauv kev tsim khoom. Plywood feem ntau siv sai -}}}}}}}}, ntoo thuv, uas xav tau cov kev hloov kho thiab qee yam tsis xws luag. Tom qab pom, lub cav yog ntu mus rau hauv qhov ntev rau kev ua tiav.

Veneer npaj yog ib tug txheej txheem tseem ceeb. Lub cav yog tev lossis hlais los tsim cov pa dej ntawm cov khaub ncaws tsis zoo (feem ntau 0.5 {{3 hli). Peeling is suitable for high-volume production and offers high efficiency, while slicing produces smoother veneers and is often used in high-end products. Cov pas dej tau qhuav los tswj cov ntsiab lus ya raws ntawm 8% -12% los xyuas kom zoo thaum lub sijhawm gluting.

Thaum lub sijhawm cov txheej txheem gluing thiab cov txheej txheem sib dhos xws li urea - Daim ntawv tso cai los yog tusyees siv rau qhov chaw nyob. Tus nqi ntawm cov nplaum yuav tsum tau nruj me ntsis tswj hwm kom ntseeg tau lub zog thiab ib puag ncig ua phooj ywg. Tom qab ntawd cov pa yuav tsum tau npaj ua tus lej khib ntawm cov khaubncaws sab nraud povtseg ntawm cov khaubncaws sab nraud povtseg (xws li 3, lossis 7), nrog cov fibers ntawm cov txheej txheem nyob ib sab cov neeg kho tshuab ruaj khov ntawm lub rooj tsavxwm. Tom qab sib dhos, ua ntej ua ntej -} nias yuav tsum tau pib ruaj khov cov qauv thiab tshem tawm huab cua.

Kev nias kub yog ib kauj ruam tseem ceeb hauv kev txiav txim siab cov kev ua tau zoo ntawm plywood. Tom qab pre -} Nias, cov Veneers tau nias nyob rau hauv cov kub (0.8-1.5 MPa) los kho cov nplaum thiab ruaj ntseg cov khaubncaws sab nraud povtseg ua ke. Lub sijhawm nias kub nias nyob ntawm qhov tuab ntawm lub rooj tsavxwm, feem ntau tau los ntawm ob peb feeb txog ntau feeb.

Tshaj tawm -} kev suav nrog trimming, sanding, thiab tshuaj xyuas. Trimming tshem tawm burrs, sanding smoothes saum npoo, thiab thaum kawg, ntsuas pom, thickness, thiab brickness, thiab brickness, thiab bond zog ua kom muaj zog ua kom ua tiav.

Lub Plywood Cov Txheej Txheem Ntau Lawm ua kom cov tsis muaj zog ntawm txhua qhov txuas, thaum kawg- lub zog, ruaj khov, cov tswv cuab thiab cov tswv yim ua lag luam kom tau txais kev lag luam sib txawv.
