As we all know, laminate flooring is generally composed of four -layer materials, which are wear -resistant layer, decorative layer, high density substrate layer and moisture -proof layer.
What I want to say today is the raw material aluminum oxide used in the outermost wear -resistant layer. For aluminum oxide ,according to manufacturing technique,there are mainly calcined aluminum oxide and fused aluminum oxide. With the development of science and technology,more and more producers have been using fused aluminum oxide to meet endusers’ high requirement. Then white fused aluminum oxide was chosen and what are the characteristics of it?
Fused Aluminum oxide is made of industrial alumina as the raw material and refined crystals by melting. Its hardness is much higher than calcined aluminum oxide (Mohs hardness 7.0). , Strong grinding ability, small heat, high efficiency, acid -alkali resistance, high temperature resistance and high stability.
