Raws li koj tuaj yeem pom hauv cov qauv teeb duab ntawm lub qhov cub ntoo ntsuas qhov rooj, muaj sab hauv txheej txheej npe hu ua crossband adhering rau cov tub ntxhais tiv thaiv hluav taws. Nquag, nws yog plywood lossis MDF.
Thiab hnub no, peb yuav los saib txog plywood, ib daim txiag uas nkawd yooj yim to taub tab sis ua tsis tau.
Plywoodyog cov ntoo txua khoom tsim los ntawm cov khaubncaws sab nraud povtseg ntawm nyias cov ntoo ntawm cov ntoo veneer uas yog lo ua ke. Nws tau pom raws li ib tus tswv cuab ntawm tsev neeg ntawm cov rooj tog zaum tsim.
Raws li ntoo tiag tiag, nws tseem yog lub ntuj tsim hluav taws xob, thiab yog li muab kev tiv thaiv zoo thaum kub. Kuj nrog nws cov cuab yeej zoo tiv thaiv hluav taws, nws yog qhov kev xaiv zoo rau cov hluav taws kub ntoo qhov rooj.
Muab ib daim tshev ze ntawm daim plywood, koj tuaj yeem pom qhov ua tau zoo thiab tsim qauv nws muaj.
Ua ntej, me thiab lower-zoo plywood tuaj yeem tsuas cais nws cov khaubncaws sab nraud povtseg ntawm cov ces kaum kom sib tau. Cov khoom ua tau zoo tshaj ua cov plywood yuav muab faib ua 5 txheej hauv qib 45 degrees (0, 45, 90, 135, thiab 180 degrees) los muab lub zog ua kom ruaj khov. Qhov no pab ntxiv dag zog rau tag nrho cov qhov rooj nplooj qauv ntawm cov ntoo hluav taws nyob qhov rooj.
Qhov thib ob, plywood ib txwm muaj tus lej ntawm cov txheej txheej, xws li 3, 5, 7. Yog li ntawm no tuaj rau lo lus nug: Vim li cas lawv txhua tus-txheej? Lub hom phiaj ntawm kev siv tib txheej ntawm plywood yog ua kom cov plywood muaj cov txheej nruab nrab, uas tuaj yeem ua cov phaj nyias ntawm ob sab los txwv los ntawm cov tub ntxhais txheej, kom lub nruab nrab txheej kuj tseem muaj nyob hauv txheej txheej sab nraud. Yog li ntawd, nws ib txwm muab cov ntawv lo nplaum ua ke nrog ib qho kab rov tav raws li cov noob, thiab ib qho yog sib tshooj thiab nplaum ua ke kom cov khaubncaws sab nraud povtseg sib tshooj sib xyaw thiab tsis yooj yim rau kev ua kom tawg lossis tawg.
