Kev ua haujlwm ntawm cov kua nplaum txheej tshuab tsis tsuas yog cuam tshuam rau gluing zoo ntawm veneer, tab sis kuj txiav txim siab tus nqi ntawm cov kua nplaum siv, uas cuam tshuam rau cov nqi ntawm cov plywood. Yog li ntawd, cov txheej txheem hauv qab no yog tsim los ntawm cov kua nplaum txheej tshuab.
1. Txhim kho lub uniformity ntawm cov kua nplaum txheej ntawm tag nrho cov dav ntawm veneer. Cov kev ntsuas tshwj xeeb yog raws li hauv qab no:
(1) Ua kom muaj kev tsim khoom thiab kev teeb tsa raug ntawm cov kua nplaum txheej tshuab qhov chaw. Piv txwv li, xyuas kom meej tag nrho ntawm qhov ua hauj lwm nto ntawm cov kua nplaum txheej cov menyuam thiab nyem cov menyuam mus rau lub axis, lub parallelism ntawm sab sauv thiab qis cov kua nplaum txheej rollers, thiab cov parallelism ntawm nyem cov menyuam thiab cov kua nplaum txheej cov menyuam.
(2) Tsim nyog nce txoj kab uas hla ntawm cov kua nplaum txheej rau cov menyuam.
(3) Raws li kev sib txawv ntawm cov kua nplaum, cov roj hmab coated los ntawm cov kua nplaum txheej cov menyuam tau txais kev sib txawv hardness, thiab qhov zawj ntawm cov menyuam yaus siv cov duab sib txawv thiab qhov loj me.
2. Txhawm rau hloov mus rau veneers ntawm cov thicknesses sib txawv, qhov sib txawv ntawm cov txheej txheem ntawm cov kua nplaum sab saud thiab qis qis yuav tsum tau kho, thiab cov tuab ntawm cov nplaum txheej yuav tsum yooj yim los tswj thiab kho. Lub thickness ntawm cov kua nplaum txheej yog tsuas yog txiav txim los ntawm qhov sib txawv ntawm cov kua nplaum squeezing cov menyuam thiab cov kua nplaum txheej cov menyuam. Kev hloov kho qhov tseeb ntawm qhov sib txawv yuav tsum tau tswj ntawm li 0.01mm, thiab cov kua nplaum txheej yog feem ntau tswj nyob rau hauv thaj tsam ntawm 105-430g/m2.
3. Txhim kho qhov hnav tsis kam thiab xeb tsis kam ntawm qhov chaw ntawm lub tshuab ua kua nplaum, thiab teeb tsa cov cuab yeej tiv thaiv kev nyab xeeb tsim nyog los ua kom lub neej ntawm cov kua nplaum txheej tshuab thiab ua kom muaj kev nyab xeeb.
