FOR300H1 Lecture Notes - Lecture 3: Fiberboard, Resorcinol, Hot Press
Document Summary
Glued laminated lumber. beams wood based architecture ex ago small diameter woods. Potential for high efficiency of wood use by engineering design. very nice and smooth. fiberboard used in table can be divided in by the compressed percentage. At the forming station, they put fibers at there. < video: wisa plywood production process > one single continuous panel- multilayers. < video: particle board> image: like the cork of the wine bottles. Norbord- canadian company log size is so much smaller than previous one. low quality it is hard to hold the heavy things. Bc is the first one: michael green at ted2013. ex. < hot press> density heat will activate the glue. Urea formaldehyde - one of the cheapest thing not a good one. not stable. < resorcinol resins> bit expensive. no need of heat. Mdi- no color, can also react with water, very good glue. Make beams carry a lot of log. black glue line - endurable.
