Kev piav qhia ntxaws ntawm Cov Khoom Ntoo Ntoo Plywood Manufacturing Process
Khoom ntoo spliced panels yog tsim los ntawm gluing nqaim strips ntawm ntoo ua ke horizontally thiab thov ib tug veneer. Txhawm rau txhim kho kev zoo nkauj thiab ua haujlwm ntev, qhov saum npoo feem ntau npog nrog cov tawv ntoo veneer lossis embossed. Cov hom muaj xws li cedar boards thiab rubberboard boards.
Ncaj splicing (flat splicing) yog ib txoj kev siv dav dav, cov tub ntxhais uas ua kom cov seams nruj thiab tiaj tus. Cov txheej txheem tseem ceeb yog raws li nram no:
I. Kev xaiv cov khoom siv: Tshem tawm cov ntoo uas pom tseeb, cov kab nrib pleb, lossis lwm yam tsis xws luag kom ntseeg tau tias cov khoom siv raw zoo sib xws thiab lav qhov zoo thiab ruaj khov ntawm cov khoom tiav los ntawm qhov chaw.
II. Kev Npaj Khoom Siv: Siv lub rooj pom los txiav cov ntoo ntxhib kom loj me ntsis ntawm lub hom phiaj loj, tawm hauv cov nyiaj ua haujlwm.
Siv lub planer thiab thickness planer los ua cov ntoo mus rau ib qho tuab tuab, feem ntau tawm 2-3 hli ntau tshaj qhov kawg lub hom phiaj kom them nyiaj rau cov xuab zeb tom ntej.
III. Sib dhos: Teem thiab phim cov laug cam raws li cov ntoo lis, xim, thiab cov ntsiab lus noo noo. Kev sib sau ua ke zoo sib npaug ntawm cov kev ntxhov siab sab hauv ntawm cov ntoo, uas yog qhov tseem ceeb rau kev tiv thaiv deformation thiab tawg ntawm cov khoom tiav.
IV. Daim ntawv thov kua nplaum
Siv cov kua nplaum ntoo sib npaug rau qhov sib txuas ntawm qhov chaw, tswj tus nqi thiab ua kom muaj kev faib tawm los lav kev sib raug zoo ntawm lub zog thiab tsis txhob muab cov kua nplaum dhau ntawm lub rooj tsavxwm.
V. Clamping thiab kho
Siv cov clamps los siv lub siab sib xws rau cov laug cam, kom ntseeg tau tias muaj kev sib haum xeeb ntawm cov pob qij txha.
Cia cov laug cam kho nyob rau hauv ib qho chaw zoo kub thiab av noo kom cia cov nplaum rau tag nrho cov tawv nqaij. Thaum lub sijhawm txheej txheem no, tswj kev ntxhov siab ntawm cov laug cam kom tiv thaiv kev ntxhov siab deformation.
Cov yam ntxwv txheej txheem
Direct splicing yog txheej txheem yooj yim nrog kev ua haujlwm siab thiab siv cov khoom siv zoo. Cov khoom tiav lawm muaj qhov zoo xws li cov qauv kev ruaj ntseg, siab nto flatness, thiab yooj yim ntawm kev ua haujlwm tom qab, ua rau nws yog ib txoj hauv kev tsim cov rooj tog ntoo thiab cov ntaub ntawv zoo nkauj.
Los ntawm kev xaiv cov khoom siv, kev ua tiav, thiab cov txheej txheem gluing, ncaj qha splicing khoom ntoo boards tuaj yeem khaws cov khoom zoo nkauj ntawm cov ntoo thaum txhim kho qhov ntev thiab kev siv cov khoom siv.
