Nrog kev txhim kho txuas ntxiv ntawm vaj huam sib luag thev naus laus zis, qhov zoo ntawm cov khoom vaj huam sib luag tau zoo heev. Muaj qhov sib txawv ntawm cov txheej txheem tsim khoom thiab cov txheej txheem ntawm ntau lub tuam txhab, raws li cov khoom siv tseem ceeb rau kev tsim cov khoom siv ntoo, cov khoom ntoo lossis cov ntoo laminated, hauv kev tsim khoom thiab cov khoom tiav, yog tias cov txheej txheem ntau lawm tsis zoo tswj, warping thiab cracking phenomenon yog ib qho yooj yim mus tshwm.
Ua ntej, cov teeb meem tseem ceeb
1. Ntau tus neeg siv me me thiab nruab nrab muaj kev nkag siab tsis zoo txog qhov tseeb ntawm cov ntoo (flatness) thiab qhov tseeb ntawm substrate, tias cov ntoo tsis sib xws tsis muaj kev cuam tshuam ntau, thiab cov kua nplaum yuav ua rau qhov khoob. Txhawm rau xyuas seb lub rooj tsavxwm puas tiaj tus, tsuas yog nyem ob peb daim ntoo ntawm tes thiab saib seb puas muaj qhov khoob.
2. Cov teeb meem ntawm cov kua nplaum: hom kua nplaum siv tsis sib xws rau cov khoom siv, yog li lub zog ntawm cov kua nplaum tsis tuaj yeem ua tiav, thiab qhov adhesion yog raws li cov tshuaj tiv thaiv ntawm cov tshuaj tua kab mob thiab cov kua nplaum tseem ceeb. Lub zog tseem ceeb ntawm qhov nkhaus pom cov kua nplaum nws tus kheej yog qhov tsawg, yog li nws yog ib qho tseem ceeb heev uas yuav tsum sib tov cov tshuaj tua kab mob raws li tus qauv. Thaum siv, qhov kev faib ua feem ntawm curing agent yog tsawg, thiab daim ntawv cog lus lub zog thiab dej tsis kam yog txo qis, thiab tus nqi tawg tau zoo heev.
Qhov thib ob, muaj qhov teeb meem ntawm cov tshuab
Lub siab ntawm lub tshuab tsis txaus, thiab qhov deformation yuav tshwm sim los ntawm lub siab tsis txaus lossis tsis sib xws thaum lub sij hawm pressurization. Yog tias lub sijhawm kho tsis txaus, cov kua nplaum yuav tawg thiab tso dej tom qab ua tiav. Plywood laminated ntoo yuav tsum tau muab tso rau tsawg kawg 24 teev ua ntej kev kho mob saum npoo, tshwj xeeb tshaj yog kev kho deg yuav tsum tau muab tso rau lub sijhawm ntev, thiab kev ua haujlwm ceev ntawm kub nias thiab cov plywood ntau zaus yuav nrawm dua.
Yog li ntawd, peb tuaj yeem siv cov kev ntsuas coj los txhim kho qhov zoo ntawm cov khoom ntoo raws li qhov tseeb ntawm qhov muaj pes tsawg leeg, ntau npaum li cas thiab cov cuab yeej siv tshuab ntawm cov nplaum.
1. Thaum lub vaj huam sib luag ntoo uas muaj qhov tsim nyog tau tsim, tib hom ntoo lossis ntoo uas muaj qhov sib txawv ntawm qhov sib txawv tsis ntau tshaj 0.2g / cm³ yuav tsum tau siv. Yog tias siv ntoo nrog qhov sib txawv loj ntawm qhov ntom ntom thiab shrinkage, qhov kev ntxhov siab sab hauv ntawm lub rooj tsavxwm yuav nce ntxiv.
2. Siv cov kua nplaum kom raug. Thaum lub sij hawm kho cov txheej txheem ntawm cov nplaum, cov nplaum dej nplaum yuav txo qis thiab ua kom muaj kev ntxhov siab sab hauv, yog li txo qhov kev sib txuas ntawm lub zog thiab qhov kev ntxhov siab sab hauv yog txo qis.
3. Kev siv cov cuab yeej siv hluav taws xob ntau zaus tuaj yeem daws cov cua kub ceev, cua sov ua haujlwm, tsis siv neeg ntau lawm, kev tiv thaiv ib puag ncig, kev nyab xeeb thiab lwm yam teeb meem.
