Dab tsi yog qhov poob hauv Cov Txheej Txheem Ntau Lawm ntawm Plywood
Aug 10, 2022
Nyob rau hauv tag nrho cov txheej txheem ntawm plywood, ziab ntawm cov tub ntxhais lub rooj tsavxwm, kev ua tiav ntawm qhov khoob, kub nias, trimming, thiab xuab zeb muaj kev cuam tshuam rau cov ntoo poob, uas tau muab faib ua tangible poob (nrog rau cov khoom seem) thiab tsis pom kev poob (qhuav shrinkage thiab compression). Kev poob ntoo muaj feem cuam tshuam nrog rau yam xws li hom cav, cav specifications, cov cuab yeej siv, txheej txheem thev naus laus zis, thiab cov txheej txheem ua tiav.
Core board drying: Lub core board tom qab txiav cov khoom muaj cov ntsiab lus siab noo noo, thiab cov core board yuav tsum tau qhuav kom ua tau raws li cov txheej txheem gluing. Qhov loj ntawm cov ntoo ua me me tom qab ziab, uas yog hu ua drying shrinkage. Raws li cov ntsiab lus noo noo txo, qhov ntev, dav thiab thickness ntawm cov tub ntxhais yuav shrink. Lub shrinkage poob yog muaj feem xyuam rau cov ntoo hom ntawm lub core board, noo noo cov ntsiab lus ntawm lub core board thiab thickness ntawm lub core board. Qhuav shrinkage poob tus nqi feem ntau yog 4 feem pua rau 10 feem pua.
Kev sib dhos ntawm qhov khoob: Kev ua tiav ntawm qhov khoob muaj xws li txiav, sib dhos thiab kho. Txiav cov sawb-zoo li tus core board thiab xoom-thooj core board rau hauv specification core board thiab splicable core board, lub nqaim sawb core board yog spliced rau hauv ib tug tag nrho core board, thiab lub puas core board yuav tsum tau kho kom tiav cov txheej txheem. Cov kev xav tau zoo. Tus nqi ntawm cov khib nyiab core board tsim nyob rau hauv cov txheej txheem no feem ntau muaj feem xyuam rau tus neeg teb xov tooj kom paub txog cov txheej txheem core board thiab qhov zoo ntawm cov core board. Tus nqi poob feem ntau yog 2 mus rau 4 feem pua.
Kub nias: Cov nplaum nplaum nplaum nplaum nplaum nplaum ua ke los ntawm qee qhov kub thiab qhov siab. Thaum lub sij hawm kub nias, raws li qhov kub thiab noo cov ntsiab lus ntawm cov slab hloov, cov ntoo yog maj mam compressed, thiab lub thickness ntawm lub slab yuav maj mam txo. Qhov kev poob no yog compression poob, uas muaj feem xyuam rau qhov kub nias kub, chav tsev siab, kub nias lub sij hawm, hom ntoo thiab noo noo cov ntsiab lus ntawm plywood. Tus nqi poob feem ntau yog 3 feem pua rau 8 feem pua.
Trimming: Txiav cov ntaub plaub kub nias rau hauv cov ntawv qhia tshwj xeeb. Tus nqi ntawm kev txiav ntug khib nyiab yog cuam tshuam nrog kev ua haujlwm pub dawb ntawm cov plywood thiab qhov loj ntawm qhov dav. Qhov loj dua qhov dav ntawm cov plywood, qhov tsawg dua qhov txiav ntug poob, feem ntau 4 feem pua rau 6 feem pua.
Sanding: Xuab zeb rau saum npoo ntawm cov plywood ua kom lub ntsej muag du thiab zoo nkauj. Cov khib nyiab tsim nyob rau hauv cov txheej txheem no yog sanding hmoov. Thaum qhov zoo ntawm lub rooj tsavxwm yog qhov zoo, cov xuab zeb xuab zeb me me, thiab cov xuab zeb poob feem ntau yog 2 mus rau 5 feem pua.
