Common problems of fireproof board and their solutions

Fireproof board, also known as fire-resistant board, scientific name is thermosetting resin impregnated paper high-pressure laminate, English abbreviation is HPL {pecrativehigh pressure lcminate}, which is a fire-resistant building material for surface decoration. It has rich surface color, texture and special logistics performance, and is widely used in interior decoration, household appliances, kitchen cabinets, laboratory tables, external walls and other fields. The fireproof board is made of base paper (titanium powder paper and kraft paper) through the impregnation process of melamine and phenolic resin and high temperature and high pressure.

Introduction to common problems and treatment methods of fireproof board

Defects and solutions in the production of fireproof board

1、 There are white flowers on the board surface

Causes:

1. The glue content of the top paper is insufficient or the local resin is solidified during drying

2. The volatile content of surface paper is too low

3. Hot pressing type: uneven pressure

4. Cushion material is inelastic

5. Stainless steel plate indicates unevenness

6. The resin reaction is too old, the molecule is too large, and the resin fluidity is large

Solution:

1. Increase the resin content of surface paper or control the drying temperature to prevent local resin curing

2. Improving volatile content of surface paper

3. Overhaul the hot press and improve the uniformity of the pressing surface

4. Replace cushion materials regularly

5. Regular polishing of stainless steel plate

6. The resin shall be analyzed and inspected, and shall be stopped when the unqualified index is required
