The amount of glue
Tyrsolit, made with a binder in an amount of 8% and not lined with texture paper, has a static bend on average 233 kg/cm2, which is several times higher than the average strength of stem chips. The literature on the production of chipping plates states that to obtain slabs from sawdust requires a larger amount of binder, since the flow of glue increases with an increase in the surface of wood particles per unit volume. This position is incorrect. Temporary premises for workers, the first about what you need to take care of the construction site. By acquiring construction households from Stroy Gid, you will always be confident in their high quality. Sawdust have a large surface than shavings, in a unit volume. The strength of the stove from small waste depends on the number of adhesive bridges between the particles. When mixing, the glue is relatively well absorbed by sawdust, which usually refers to a negative phenomenon in the literature. During pressing, the sawdust also easily give the binder, as they absorb it. This is due to a small area of glue advancement in sawdust and a strongly developed end surface, which is not characteristic of chips. The glue squeezed from sawdust moistens adjacent particles, creating a large number of glue bridges. This explains the interesting feature of Tyrsolite, which consists in the manifestation of insignificant irreversible deformations after soaking in water and subsequent drying. There is such a large number of glue bridges in Tyrsolite that only the surface layer of particles with unilateral gluing is subjected to swelling during soaking. The middle particles, being glued together with waterproof glue, are not extended throughout their plane. This is a very important property of tyrsolite. Tyrsolite is recommended to release the following thicknesses: 2, 3, 4, 5, 6 and 8 mm. Material from 2 to 4 mm will be used as facing, with large thicknesses, the sheets of tyrsolite can serve as a constructive material. The color of tyrsolite is determined by the pedigree composition of sawdust. Color sulfur can be obtained when staining sawdust with synthetic dyes. Colored tyrsolit is very beautiful for the production of panels in construction
