Cov tswv yim tu thiab kev coj ua rau Hardwood Plywood

Hardwood plywood, nrog nws lub zog zoo heev, zoo nkauj nplej, thiab zoo seem ruaj khov, plays lub luag haujlwm tseem ceeb hauv kev kho kom zoo nkauj sab hauv thiab sab nrauv, rooj tog tsim, thiab kev tsim vaj tsev. Txawm li cas los xij, kev ua tau zoo txuas ntxiv ntawm nws qhov zoo nyob ntawm kev tshawb fawb thiab kev saib xyuas zoo. Kev saib xyuas kom zoo tuaj yeem tsis tsuas yog ncua kev laus ntawm cov plywood thiab tiv thaiv kev deformation thiab kev puas tsuaj, tab sis kuj tseem tuav nws qhov siab - zoo li zoo thiab muaj nuj nqi nyob rau lub sij hawm ntev - siv.
Kev saib xyuas ntawm hardwood plywood yuav tsum xub tsom rau kev tswj hwm ib puag ncig. Cov khoom no yog rhiab heev rau cov kev hloov ntawm huab cua humidity thiab kub. Lub sijhawm ntev ntawm cov av noo tuaj yeem ua rau muaj kev nqus dej noo thiab nthuav dav, ua rau pwm loj hlob, thaum qhuav qhuav tuaj yeem ua rau shrinkage thiab tawg. Cov av noo zoo tagnrho rau kev khaws cia thiab siv yuav tsum khaws cia ntawm 45% thiab 65%, thiab qhov kub yuav tsum tau khaws cia ntawm 10 txog 30 degrees Celsius. Xyuas kom muaj qhov cua zoo nyob hauv qhov chaw kom tsis txhob muaj qhov hnyav lossis qhov dej, thiab siv qhov tsim nyog dehumidification lossis humidification ntsuas thaum lub caij hloov pauv lossis huab cua huab cua los txo qhov cuam tshuam ntawm ib puag ncig kev ntxhov siab ntawm cov plywood.
Kev tu txhua hnub yuav tsum tau ua kom maj mam. Siv ib daim ntaub mos muag los yog ib daim ntaub ntub dej me ntsis kom tshem tawm cov plua plav thiab cov stains, tsis txhob yaug dej ncaj qha los yog siv lub dav hlau dej siab siab - kom tsis txhob ya raws ntawm cov plywood. Cov tshuaj ntxuav tu yuav tsum yog nruab nrab thiab tsis yog-corrosive; tsis txhob siv cov khoom uas muaj cov kua qaub, muaj zog alkalis, lossis cov kuab tshuaj organic los tiv thaiv kev puas tsuaj rau cov xim pleev xim rau saum npoo los yog ntoo fibers. Rau hardwood plywood nrog veneers los yog coatings, tsis txhob siv abrasive tu cov cuab yeej los tiv thaiv khawb qhov nto gloss.
Kev tiv thaiv yog ib feem tseem ceeb ntawm kev saib xyuas. Rau cov cheeb tsam uas muaj dej noo, ob sab ntug sealing lossis siv cov dej noo- cov ntaub ntawv pov thawj tuaj yeem txhim kho cov dej tsis kam; Nyob rau hauv qhov chaw raug tshav ntuj ncaj qha los yog qhov kub thiab txias hloov, shading los yog rwb thaiv tsev cov chaw yuav tsum tau muab ntsia kom qeeb deg fading thiab nplaum aging. Thaum tuav thiab teeb tsa, zam kev cuam tshuam hnyav thiab cov khoom ntse khawb. Thaum kho, xaiv cov connectors tsim nyog thiab qhov sib nrug los tiv thaiv lub zos deformation los yog delamination vim kev ntxhov siab concentration.
Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua kuj tseem yog qhov tseem ceeb. Lub vaj huam sib luag saum npoo yuav tsum raug tshuaj xyuas ib ntus rau cov kab nrib pleb, hlwv, pwm, lossis delamination ntawm cov npoo, thiab kho lossis hloov ntsuas yuav tsum tau ua kom sai. Rau cov vaj huam sib luag uas tsis tau siv rau lub sijhawm ntev, cov xwm txheej cia yuav tsum tau rov xyuas dua -, thiab txoj haujlwm yuav tsum tau hloov kho lossis cov hlua txhawb nqa rov qab raws li xav tau kom sib npaug ntawm ib puag ncig. Yog hais tias cov txheej txheej saum npoo qhia tau tias hnav, nws tuaj yeem sanded thiab tiv thaiv cov xim siv raws li cov khoom xav tau los kho nws cov kev tiv thaiv thiab kho kom zoo nkauj.
Zuag qhia tag nrho, kev saib xyuas ntawm hardwood plywood yog txheej txheem txheej txheem uas suav nrog kev tswj hwm ib puag ncig, ntxuav thiab tiv thaiv, thiab tshuaj xyuas tsis tu ncua. Tsuas yog los ntawm kev hais txog ntau yam thiab ua kom muaj kev sib raug zoo tuaj yeem ua rau nws lub sijhawm ntev - ua haujlwm tau zoo thiab txhim khu kev qha tau ua kom ntseeg tau hauv ntau yam kev thov.
