(1) Surface wear layer
The biggest feature: wear resistance, durability
Factors of wear resistance: Al2O3 or silicon carbide (SIC) is uniformly and finely attached to the surface of the decorative layer.
u Measure the good or bad wear resistance: depending on the content of AL2O3 and SIC in the wear layer, the more the content, the greater the surface wear resistance.
(2) Decorative layer
u One layer of printing paper, printed by computer simulation technology.
u decorative layer has two structures: one decorative paper and two decorative papers and the bottom paper
The effect of the bottom paper: the decorative layer has a certain thickness and mechanical strength, and the thickness is about 0.2-0.3 mm. Decorative paper patterns are: flat, inlaid stone, pearl, convex and concave, wood grain
(3) Substrate layer
The substrate is the main structure of the laminate flooring and determines the quality of the product.
Medium-density fiberboard, high-density fiberboard (HDF), particleboard, usually made of fast-growing wood such as pine, poplar, and miscellaneous wood. The living home uses high-density fiberboard.
How to distinguish between good and bad substrates: look, smell, cook
(4) Balance layer (and moisture barrier)
The laminate, impregnated paper or veneer is decorated with a thermosetting resin.
The thickness is approximately equal to the wear layer plus the decorative layer, which has the function of moisture proof and stable product size, so that the floor is evenly stressed during processing and use.
DIN Flanges are circular flanges for pipes, valves, fittings, and accessories. There are DIN Standard Flange,DIN2566 Threaded Flanges,DIN Plate Flanges.
