alwaax

Plywood, oo ay weheliso guddiga qayb ka mid ah jihaysan (OSB), fiberboard cufnaanta dhexdhexaadka ah (MDF), iyo guddiga qayb (ama guddiga qayb), waa mid ka mid ah alaabta injineernimada ee tirada badan ee loo isticmaalo dhismaha.Lakabyada ku jira alwaaxdu waxay tixraacaan maraqa alwaax ah, kuwaas oo la dul saaray midba midka kale xagal 90 darajo ah oo isku xiran.Habaynta beddelka ahi waxay siisaa xoog dhismeed oo loogu talagalay badeecada ugu dambeysa, halka ay ka duwan tahay qaar ka mid ah alaabada kale, alwaaxdu waxay leedahay muuqaal caadi ah oo alwaax ah.

Plywood waa alwaax alwaax ah oo ugu fiican oo loo isticmaalo dhismaha iyo qurxinta ujeedooyinka.Our plywood ayaa la kulma heerka caalamiga ah ee alwaax (sidaEPA,CARB,) .Waxaan bixinaa xaashida alwaaxa sida alwaax adag, alwaax bjørk, alwaax badeed, alwaax poplar, plywood WBP ee gudaha iyo /ama codsiyada dibadda.
Plywood waa guddi ka kooban qaar ka mid ah phies of veneers. The veneers waxaa laga diiray alwaax alwaax ah, sida alwaax, bjørk, poplar, alwaax, geed, iwm. Kuwan alwaax ugu dambeyntii la isku xidhi doonaa si wada jir ah koolo hoos cadaadis sare iyo heerkulka sare .
Noocyada alwaaxda
Waxaa jira noocyo badan oo alwaax ah oo kala duwan, inkastoo ay jiraan laba nooc oo waaweyn oo alwaax ah kuwaas oo si gaar ah ugu badan mashaariicda dhismaha guryaha:

alwaax jilicsan
Caadi ahaan ka samaysan spruce, geed, ama beroosh ama kedar, alwaax jilicsan ayaa loo isticmaali karaa gidaarada, sagxadaha, iyo saqafka.
alwaax adag
Sida alwaax jilicsan, alwaax adag ayaa sidoo kale loo isticmaalaa mashaariicda dhismaha, laakiin waxay u baahan tahay xoog dhismeed sare iyo caabbinta waxyeellada.Badanaa waxaa laga sameeyaa bjørk, geed, ama mahogany.bjørk Baltic waa nooc gaar ah oo alwaax bjørk ah oo laga sameeyay Yurub.Waxay caan ku tahay biyuhu iyo muuqaalkeeda wacan, taas oo ka dhigaysa doorasho caan ah oo loogu talagalay armaajooyinka.
Qoryaha qurxinta
Sida magacu soo jeediyo, alwaax daboolan (ama qurxin) alwaax waxaa loogu talagalay in lagu daboolo saaraha oo ay sameeyaan dusha rinji oo siman.Qoryaha loo isticmaalo in lagu daboolo alwaaxda waxaa ka mid ah dambas, bjørk, mahogany, maple, iyo geedkii.

Laacidda ama alwaax dabacsanaan

Maaddaama tani inta badan aysan ahayn badeeco badan oo lakab ah, laakiin hal lakab oo lakab ah oo alwaax kuleyl ah, waxaa la odhan karaa ma aha mid dhab ah.Alwaax dabacsan ayaa sida caadiga ah loo isticmaalaa armaajooyinka iyo alaabta guriga kale, laakiin adeegsigeeda qaab dhismeedkeeda waxaa ka mid noqon kara jaranjaro wareeg ah iyo saqafyo fidsan.
Qoryaha badda
Alwaax darajada badeed waxaa loogu talagalay xaaladaha laga yaabo inay qoyan yihiin muddo dheer.Tan waxaa ku jiri kara maraakiib, laakiin sidoo kale waxaa badanaa loo isticmaalaa armaajooyinka dibadda, sagxadaha marmar, iyo tas-hiilaadka kale ee bannaanka ee meelaha xeebaha ah.
Qoryaha diyaaradda
Qoryaha diyaaraduhu waxay inta badan ka samaysan yihiin bjørk, Okoume, mahogany, ama spruce, waxaana mararka qaarkood loo isticmaalaa samaynta diyaarad, in kasta oo ay leedahay adeegyo kale oo kala duwan, laga bilaabo alaabta guriga ilaa qalabka muusikada.Waxay si gaar ah u adkaysataa kulaylka waxayna u adkaysataa qoyaanka.

darajada alwaax
Aqoonta darajada alwaaxdu way u fududahay sida A, B,C… dhanka kalena waa tayada darajada B.
J: Tani waa alwaaxa ugu tayada sarreeya, oo leh dusha siman oo aan lahayn guntin ama dayactir.
B: Heerkani asal ahaan ma laha guntin, in kasta oo qaar cidhiidhi ah (in ka yar 1 inch) la aqbali karo.
C: alwaax darajada C waxa ku jiri kara guntiyo ilaa 1.5 inji ah iyo guntiyo ka hooseeya 1 inch.
D: Heerka ugu yar wuxuu yeelan karaa qaybo iyo godadka ilaa 2.5 inji oo dherer ah.Guud ahaan, wixii cillad ah laguma hagaajin alwaax darajada D ah.
X: X waxa loo isticmaalaa in lagu matalo alwaax dibadda ah.Darajada CDX waxay ka dhigan tahay in hal lakab oo alwaax ah uu yahay heerka C-da kalena uu yahay D-grade, oo si gaar ah loogu isticmaalo dibadda.
alwaax darajada guud waxa loo qori karaa sidan soo socota:
Qoryaha B/BB
alwaax darajada BB/CC
alwaax darajada DBB/CC
C+/C alwaax geedeed - ciid & fidsan

Cabbirka alwaax
Cabbirka alwaaxda ugu caansan Maraykanka waa 4 cagood iyo 8 cagood, laakiin 5 cagood iyo 5 cagood ayaa sidoo kale caadi ah.Cabbirrada kale waxaa ka mid ah 2'x2', 2'x4', iyo 4'x10'.
Dhumucdiisuna waxay u dhaxayn kartaa 1/8 inch, 1/4 inch, 3/8 inch… ilaa 1 1/4 inch.Fadlan ogow in kuwani yihiin cabbiro magac-u-yaal ah, cabbirada dhabta ahna ay inta badan yihiin kuwo khafiif ah.Inta lagu jiro habka diyaarinta alwaaxda, qiyaastii 1/32 inch oo dhumucdiisuna waxay lumin kartaa suufka dartiis.
