We all know that plywood is a building board that we often use. This board is not cut out of a piece of wood but is glued together with a thin board of wood. People sometimes worry that the plywood produced by plywood manufacturers will have poor glueability and will not crack during use. Here plywood manufacturers will give you how to measure the plywood's glue strength.
Different types of plywood determination methods are different. For Type 2.1 plywood, it must be cooked in boiling water for four hours and it should be completely immersed in water. It is then dried for 20 hours in an air convection oven placed around 63 degrees Celsius. Then boil it in boiling water for 4 hours, take it out and cool it for 10 minutes, and observe whether there is any gel opening at the plate joint. The method used for Type 2.2 plywood and Type 2.3 plywood is the same, except that the time and drying time in hot water are different. 2.5 plywood is mainly determined by means of a testing machine.
Mastering the method of measuring plywood can test whether the quality of the plywood you purchased is reliable.
