Cov txheej txheem plywood, qhov siab - Lub zog composite cov khoom siv, yog siv dav siv hauv kev tsim kho, rooj tog zaum thiab kev lag luam. Nws cov khoom lag luam zoo - bearing muaj peev xwm thiab kav ntev ua rau nws cov khoom nyiam rau ntau cov haujlwm. Txawm li cas los xij, kev saib xyuas tsis raug cai tuaj yeem ua rau deformation, tawg, thiab poob ntawm lub zog. Yog li ntawd, kev saib xyuas kom zoo yog qhov tseem ceeb heev.
Ua ntej, tswj ib puag ncig qhuav yog qhov tseem ceeb los tswj cov txheej txheem plywood. Plywood yog ua los ntawm ntau txheej ntawm veneer tau nias ua ke nrog cov nplaum. Kev ua kom ntev ntev rau noo noo tuaj yeem yooj yim nqus dej thiab swell, ua rau delamination lossis pwm. Nws raug nquahu tias cov av noo yuav tswj hwm 40% thiab 60% thaum lub sijhawm khaws thiab siv, thiab kev sib cuag ncaj qha rau dej. Yog tias nws tau ntub, so nws qhuav tam sim ntawd nrog ib daim ntaub qhuav thiab muab tso rau hauv ib qho zoo- pa kom qhuav. Zam kev tshav ntuj ncaj qha lossis siab - kub qhuav kom tiv thaiv cov nplaum los ntawm kev ua tsis ncaj.
Thib ob, kev tu ib txwm tu thiab saib xyuas tuaj yeem txuas ntxiv nws lifespan. Thaum siv txhua hnub, maj mam so cov npoo nrog cov ntaub mos muag thiab tshuaj npauj nruab nrab. Zam txhob siv cov kuab tshuaj acidic lossis alkaline cov kuab tshuaj kom tiv thaiv corrosion ntawm cov plywood nto. Rau cov txheej txheem plywood tau siv sijhawm ntev heev, nws tau pom zoo kom siv cov roj whax lossis cov kua dej tsis txaus ntseeg kom ua rau nws noo noo.
Tiv thaiv kev puas tsuaj puas yog qhov tseem ceeb. Thaum cov txheej txheem txheej txheem txheej txheem muaj lub zog siab, nws tseem yuav muaj kev tiv thaiv los ntawm cov khoom ntse thiab lub siab ntev ntawm cov khoom qub. Thaum lub sijhawm thauj mus los thiab kev teeb tsa, siv cov cuab yeej tshwj xeeb kom tsis txhob rub lossis poob.
Thaum kawg, kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua thiab kev saib xyuas yog qhov tseem ceeb los ua kom tau kev ua tau ruaj khov ntawm cov txheej txheem plywood. Kuaj xyuas kom cov cim ntawm kev tawg, deformation, lossis cov nplaum delamination. Kho txhua qhov teeb meem kom tiv thaiv cov teeb meem me me los ntawm kev muaj xwm txheej loj.
Los ntawm kev txij nkawm zoo, cov txheej txheem plyuam tsis yog tswj hwm nws cov kev pabcuam lub neej, muab kev pabcuam ntau dua thiab txhim khu kev qha ntau rau ntau yam haujlwm.
