Khoom ntoo wood:
Qhov ntau hom khoom ntoo muaj xws li: txhua yam ntawm daim hlau, cov plaub fab, curved ntoo thiab li ntawd. Sheet: Daim ntawv nrog lub thickness ntawm 18 hli yog nyias ntoo, thickness ntawm lub phaj nrab yog 19 ~ 35 hli, thiab lub thickness ntawm cov phaj tuab yog 36mm lossis ntau tshaj.
Zoo: Nws muaj qhov zoo nkauj thiab zoo nkauj kev ntxhib los mos, sov so; tsis txhob ntshai dej nyab, kav ntev thiab ntev lub neej.
Cov kev tsis zoo: ntev lub sij hawm tsim tawm, tsis tshua tawm, nqi siab, me me, kev loj loj los ntawm huab cua, ntev mus yuav deformed.
Lub rooj vaj huam sib luag tsim tau:
Lub rooj tsim khoom thaij sab laj tsuas yog: plywood, particle board, fiberboard, blockboard, hollow core board thiab li ntawm. Plywood. Cov plywood muaj ntau tshaj 3 cov khaubncaws sab nraud povtseg, cov khaubncaws sab nraud povtseg yog khib, thiab txhua txheej yog 11 hli tuab thiab cov ntoo thin yog khov thiab nias. Cov fibers wood nruab nrab ntawm cov khaubncaws sab nraud povtseg ntawm lub plywood yog biased perpendicular rau txhua tus. Lub plywood muaj ib tug loj thiab flat hom, yog loj thiab nruab nrab thickness. Nws tuaj yeem siv los ua ib lub phaj loj-xws li ntau hom ntawm cov qhov rooj, qab nthab thiab pem teb.
Zoo: cov nqi tsawg tsawg; cov me nyuam deev me me vim muaj teebmeem meteorological; hom loj, du thiab du sab nraud, yooj yim txheej txheem; zoo mechanical zog.
Disadvantages: Dej kuj tsis tshua muaj neeg ploj lawm.
Lub thawv rau khoom kom zoo nkauj yog ib lub phaj los ntawm cov tawv nqaij, seem, shavings, ntoo chips thiab zoo li cov txheej txheem ntoo. Lub thawv boxwood cam yog cov plywood, Baoli board, fiberboard, blockboard, particle board, wood board thiab ntoo ntsa board.
Muab piv rau cov ntoo, lub thawv ntawv cog lus muaj ib hom loj loj, me me kev sib txawv, du thiab du nto, thiab tsis muaj anisotropy. Lub thawv ntawv cog paj ncaj nraim yog tiaj thiab tiaj tus. Qhov feem ntau siv ntau yam nyob rau hauv kev ua lag luam yog plywood, particleboard, medium density fiberboard, blockboard thiab fireproof board.
