Fireproof HPL structure and raw materials
Share with you the structure and raw materials of fire-proof HPL , hoping to help you.
Fire-proof HPL is divided into three basic layers, the most surface layer is transparent wear-resistant layer, the second layer is decorative paper layer, and the third layer is the base layer.
Wear-resistant layer: Increase the surface wear resistance and high temperature resistance of fire-resistant leather.
Decoration layer: play a decorative effect, the main performance of fire-proof board color texture.
Base layer: Strengthen the structural strength of the fire-proof board, can adjust the thickness of the base to adjust the overall thickness of the skin.
Wear-resistant layer: Aluminum trioxide transparent paper or silicon carbide transparent paper, fire resistance and wear resistance mainly depends on this layer of paper.
Decorative layer: Melamine impregnated printing paper, the weight of general paper: 80-120 g/.
Base layer: kraft paper impregnated with phenolic resin or urea-formaldehyde resin. The weight of general paper is 140-180 g/. The thickness of fire-proof board mainly depends on the thickness of the basement layer. The more the basement layer, the thicker the fire-proof board.
What is HPL made of? It consists of about 60-70% paper and about 30-40% thermosetting resins. The latter are of two different types; the inner layers of paper are impregnated with phenolic resin and the outer layers with melamine.如无特殊说明，文章均为本站原创，转载请注明出处。If there are no special instructions, the articles are original, if you want to use or reproduce, please indicate the original source www.plywoodinspection.com,If you find that our articles infringe on your copyrights and interests, please email us at email@example.com in time and we will delete it at the first time.
