防火板有哪些常见的问题,怎么处理

  防火板的常见问题及处理方法介绍
  Introduction of common problems and treatment methods of fire-proof board
  一、板面局部有白花
  I. There are white flowers on the surface of the board.
  产生的原因:
  Reasons for this:
  1、表层纸含胶量不足或干燥中局部树脂固化
  1. Local resin curing in surface paper with insufficient gum content or in drying
  2、表层纸挥发物含量过低
  2. Low Volatile Content of Surface Paper
  3、热压式压力不均匀
  3. Hot Pressure Non-uniformity
  4、忖垫材料无弹性
  4. Inelasticity of cushion materials
  5、不锈钢板表明不平
  5. Stainless steel plate shows unevenness
  6、树脂反应过老,分子太大,树脂流动性大
  6. The resin reacts too old, the molecule is too big and the fluidity of the resin is high.
  解决的方法:
  Solutions:
  1、提高表层纸树脂含量或控制干燥温度,防止局部树脂固化
  1. Increase the resin content of surface paper or control the drying temperature to prevent local resin curing.
  2、提高表层纸的挥发物含量
  2. Increasing the Volatile Compound Content of Surface Paper
  3、检修热压机,改进加压面的均匀性
  3. Maintenance of hot press to improve the uniformity of pressure surface
  4、定期更换忖垫材料
  4. Regular replacement of cushion materials
  5、不锈钢板定期抛光
  5. Regular polishing of stainless steel plate
  6、树脂应分析检验,不合格指标要求时停止使用
  6. Resin should be analyzed and tested, and should be discontinued when unqualified indicators are required.
  二、板面有湿花(水汽),边缘较为严重
  2. Wet flowers (water vapor) on the surface of the board and serious edges
  产生的原因:
  Reasons for this:
  1、浸胶纸干燥后挥发物含量太高
  1. The volatile content of dipping paper is too high after drying.
  2、印刷木纹的油墨或染料所用的溶剂不合适
  2. Inappropriate solvents for printing wood-grain inks or dyes
  3、浸胶干燥后的胶膜纸吸湿(回潮)
  3. Hygroscopicity (moisture regain) of film paper after dipping and drying
  解决的方法:
  Solutions:
  1、降低浸胶纸干燥后的挥发物含量
  1. Reducing the Volatile Compound Content of Dipping Paper after Drying
  2、调换油墨(染料)用的溶剂
  2. Solvents for Transferring Inks (Dyes)
  3、注意胶膜纸的存放,一般可用塑料布遮盖
  3. Pay attention to the storage of film paper, which can be covered with plastic cloth.
  三、装饰板表面开裂
  3. Surface cracking of decorative board
  产生的原因:
  Reasons for this:
  1、树脂反应过嫩,分子太小
  1. The resin reacts too tenderly and the molecule is too small.
  2、树脂固化不完全
  2. Incomplete curing of resin
  3、表层胶膜纸含胶量太高
  3. The glue content of surface film paper is too high
  解决的方法:
  Solutions:
  1、不合格的树脂停止使用
  1. Discontinuation of unqualified resins
  2、适当提高热压温度或延长热压时间
  2. Appropriate increase of hot pressing temperature or prolongation of hot pressing time
  3、控制表层胶膜纸的含胶量
  3. Controlling the Glue Content of Surface Film Paper
  四、装饰板分层
  IV. Decorative Panel Layering
  产生的原因:
  Reasons for this:
  1、胶膜纸挥发物含量太低,胶膜纸在干燥时局部树脂固化
  1. The volatile content of the film paper is too low, and the film paper cures locally when it is dried.
  2、胶膜纸树脂含量不够
  2. Insufficient resin content in film paper
  3、压力过低或热压时间不够
  3. Low pressure or insufficient hot pressing time
  4、胶膜纸之间有杂物
  4. Impurities between film paper
  解决的方法:
  Solutions:
  1、控制挥发物含量不要过低,干燥温度不要过高,时间不要过长、防止树脂局部固化
  1. Control volatile content should not be too low, drying temperature should not be too high, time should not be too long, prevent local curing of resin.
  2、提高胶膜纸含胶量
  2. Improving the glue content of film paper
  3、适当提高压力含延长加热时间
  3. Increasing pressure appropriately and prolonging heating time
  4、铺模时注意清楚杂物
  4. Pay attention to the sundries when laying moulds
  五、装饰板翘曲
  V. Warpage of Decoration Board
                                                    澳门新莆京娱乐网站
  产生的原因:
  Reasons for this:
  1、各种原纸组织成分厚薄不均匀
  1. Inhomogeneous thickness of tissue components of various base papers
  2、胶膜纸含胶量不均匀,各处压力不一致
  2. The adhesive content of film paper is not uniform and the pressure is not uniform everywhere.
  3、压制过程中保温后未能进行充分冷却
  3. Failure to cool sufficiently after heat preservation during pressing
  解决的方法:
  Solutions:
  1、各种原纸应符合工艺要求
  1. All kinds of base paper should meet the technological requirements.
  2、保持树脂浓度均匀,调整挤压辊轴的间隙
  2. Keep the resin concentration uniform and adjust the clearance of extrusion roller
  3、冷却到50度以下在进行卸压
  3. Cooling below 50 degrees for pressure relief
