Cad é an sraithadhmad is láidre atá ar fáil? Tá sraithadhmad ar cheann de na hábhair is láidre a úsáidtear i dtógáil. Bíonn tionchar ag na sraitheanna grán ar leith atá suite díreach suas go dtí a chéile agus iad ag baint úsáide as gliú trí ardbhrú le linn an phróisis déantúsaíochta, bíonn tionchar ag a déine. Tá cruthúnas sáraithe go bunúsach déanta as sraithadhmad don phróiseas iomlán. Is iad na gnéithe eile a chuireann le déine na sraithadhmaid ná an tiús, na sraitheanna, an cineál gliú a úsáidtear, agus solúbthacht.
Sraithadhmad Mara mar an Sraithadhmad is Láidre
Má bhí tú fiosrach a fháil amach cad é an sraithadhmaid is láidre, ansin is é an freagra ar do cheist sraithadhmaid Mara. Cén fáth é sin? Is é an fáth go simplí ná go bhfuil na heilimintí atá riachtanach do shraithadhmad i seilbh sraithadhmaid Mara. Mar sin, tá sé aitheanta gurb é an tsraithadhmad is géire agus is láidre i measc na sraithadhmaid eile a tugadh isteach sa mhargadh.
Tá an Sraithadhmad Mara nasctha le gliúnna den scoth, dá bhrí sin feicfidh tú go bhfuil a chuid plies struchtúrach láidir agus nach féidir leo taise a chosaint. De ghnáth tugtar an sraithadhmad seo isteach i ngrád A-A, rud a thugann le tuiscint gur féidir leat aon cheann dá taobhanna a úsáid chun a thaispeáint ar an dromchla.
Cad a Dhéanann Sraithadhmad Mara an Ceann is Láidre?
Tá tionchar ag roinnt fachtóirí ar neart na sraithadhmaid mara. Léigh ar aghaidh agus bíodh a fhios agat cad a chuireann le neart sraithadhmaid na Mara.
Tiús
Cuirtear sraithadhmad na Mara, mar an sraithadhmaid is láidre i bhfeidhm ar urláir thionsclaíocha, ardaithe staighre, agus ar fhoirmeacha coincréite. Tá tiús 1-orlach ag sraithadhmaid den chineál seo agus tagann sé freisin le trims groove agus teanga a bhuaileann le chéile chun neart níos fearr a bhaint amach.
Other plywood that is commonly used has a thickness of ¾-inch and this is one of the most commonly applied thicknesses in all plywood. With a 12 x 36-inch piece of plywood in 3/4 –inch thickness, it can keep up a maximum of 50 pounds. The strength of the plywood tumbles once its thickness dwindles. For instance, a single 12 x 36-inch plywood at 1/4- inch thickness can only keep up a maximum of 5 pounds before warping.
Sraitheanna
Déantar sraithadhmad trí shraitheanna. Comhcheanglaíonn cainníocht na sraitheanna a bhaineann leis an sraithadhmad láithreach le neart. Is féidir gach ciseal a chainníochtú trí imeall na sraithadhmaid a sheiceáil. Tá sraithadhmaid na Mara comhdhéanta de níos mó ná 7 sraithe, rud a fhágann gurb é an sraithadhmaid is láidre é agus úsáidtear an t-ábhar seo go hidéalach le haghaidh tionscadail ar leith.
If you see lesser than 4 layers in ¾-inch plywood, then it would be logical to believe that it has minimal strength. This is commonly pertained to as shop-type plywood, the cheapest kind of plywood. Compared to other types of plywood, it easily breaks or bends. If the plywood is consisting of 4 to 7 layers, you can tell that it has an average extent of strength and can be employed for cabinets or nearly any other kind of project.
Cineál Gliú a Úsáidtear
Cúis eile a bhfuil sraithadhmad mara rangaithe mar an sraithadhmaid is láidre ná mar gheall ar an gcineál gliú a úsáidtear le linn déantúsaíochta. Úsáideann sraithadhmad mara gliú uiscedhíonach. Is é an buntáiste is mó a bhaineann leis an gliú seo a úsáid i sraithadhmad Mara ná nach dtiocfaidh meath ar an sraithadhmaid fiú dá n-aimseofaí é i gcoinne taise, nó teocht ard fiuchphointe, nó taise an-mhór.
Because of this, the layers of the marine plywood will not flake or crumble. You should know by now that this is an essential trait of a plywood's design especially if you are creating a boat hull using plywood. If by any chance that the protective finish of the hull is impaired and the wood is drenched, the marine plywood will stay architecturally unharmed.
Solúbthacht
The flexibility of the Marine plywood is commonly neglected. For exterior applications such as sheathing commonly positioned over 2 x 4 studs on the outer part of the home, the flexibility of the plywood is certainly an edge. Exterior grade 5/8 or 3/4 – inch plywood has adequate flexibility to defy breaking when used to rough frame structures if they are being constructed, or while adjusting the structure. This trait is called shear strength and it adds astounding strength to the structures of the frame.
Before nailing the plywood to the frame, the latter is very frail and can be easily snuffed out by a heavy wind. But once the fir plywood is used as sheathing, the flexibility of the structure dramatically upgrades, strengthening the structure. The shear strength of the plywood is incomparable to any other materials for construction.
Conclúid
Plywood is a flexible material built from resin-covered veneer pieces joined together. It can be customized to fit a comprehensive scope of structural, exterior, and interior applications. You now know the answer to the question, "what is the strongest plywood?"
Tá an sraithadhmaid is láidre nasctha le cineál níos fearr de gliú a fhágann go bhfuil na plies daingean go bunúsach agus dúshlánach i gcoinne taise. Mar gheall ar an gcineál seo sraithadhmaid láidir, is rogha iontach iad le haghaidh íoslaigh, seomraí folctha, agus mar bhunábhar le haghaidh urláir crua-adhmaid comhchoite a chur.
