Talk:Oriented strand board

message: How does OSB differ from chipboard or particle board?
osb:
thickness:6mm 8mm 9mm 12mm 15mm 18mm 21mm
size:1220*2440mm 1250*2500mm
glue:MR,WBP,E1,E2
moisture:3-12%
density:680-740kg/CBM
features of osb
1 tight construction and high strength
2 minimum twisting ,delamination and warping
3 no rotten and decay ,strong against corrosion and fire 
4 water proof ,consistent when exposed in the natural or wet environment
5 low formaldehyde emission
6 good nailing strength ,easy to be sawn,nailed, drilled,grooved,planed,filed or polished
7 good heat and sound resistant,easy to be coated  — Preceding unsigned comment added by 112.228.16.93 (talk) 09:27, 6 June 2013 (UTC)

message: While I like the even-handedness of "there is debate" over the environmental impact of OSB, I don't like the fact there's no second "hand" described.  Or listed.  Or implied.  Just, "on the one hand," OSB can be made from young and/or fast-growing (lower quality) wood.  And they don't emit much formaldehyde, which in the U.S. as a chemical would generally not be capitalized unless it's a brand name or something.
Fascinating article.   I happen to live (and have, for thirty years) downwind of an OSB plant  which, when set up, insisted publicly that it had to be sited here to access Douglas fir, which of all woods was the essential ingredient, a totally bogus claim accepted bya  desperate and ill-informed planning authority.   The introduction of potentially increasingly toxic adhesives by a new owner was handled in a comparable way.   We are now told that the children of a a downwind village several miles away are very fond of the intrusive plume from the chimney, a claim used to ease in an further environmentally intrusive expansion.  Whatever the industry's raw-material and technical safety standards these days, and its environmental record, its environmental claims need closer scrutiny than they now get.81.153.175.218 (talk) 14:26, 19 March 2017 (UTC)

thread_title:  'Buyers should ask whether zinc borate is added to their purchase.' 

message: The article states, "It is manufactured in wide mats from cross-oriented layers of thin, rectangular wooden strips compressed and bonded together with wax and resin adhesives (95% wood, 5% wax and resin)".
Of all the OSB which I have ever seen, the most that can be said is that perhaps slightly more of the flakes are oriented to the long axis on the visible layer of a 4 x 8-Ft sheet.  This is counting any flake which is at less than 45-deg to the long axis.  Who knows what goes on inside a few layers ?  
I think that most users will find the properties of these sheets to be very close to uniform in all directions.  —Preceding unsigned comment added by 68.214.128.139 (talk) 19:37, 8 September 2007 (UTC)
thread_title: WOOD-FLAKE GRAIN ORIENTATION

message: An explanation of how the resin-wax material is applied to the wood chips is needed. The example photo shows the strands laid out prior to pressing but they look very dry.  Is the adhesive applied to the chips before laying, or to the mat after it is laid?  How is consistency in the distribution of the adhesive acheived?  Is the material routinely tested by a certified (ASTM) process as it comes off the production line?
In the chipping process, it can safely be assumed that the cells along the sheer plane of each chip, and long each edge are cut open, crushed, fractured and shattered. These are the surfaces that receive the resin/wax. 
Is the wood that is used in OSB first Kiln dried, dried after chipping, or is green wood used, and assumed to be receive the equivalent of being kiln dried during the pressing process?  This is important to understand regarding the potential for insect, mold, and mildew infestations.
Is the resin typically natural or synthetic?

message: * rm Typically a 15 cm layer will produce a 15 mm panel thickness. Obviously nonsense. Is it the other way? Source? — Xiong熊talk* 23:07, 24 June 2008 (UTC)
replies: text: Seems perfectly believable to me: 15cm thick layer of chips gets compressed down to 15mm.  It's hard to imagine how the panels could be thicker than the input after being squashed. --Jaded-view (talk) 05:33, 31 August 2008 (UTC)
