   防火板是目前市場上較為常用的材質,其優點是防火、防潮、耐磨、耐油、易清洗,而且花色品種較多。防火板因其色澤艷麗,花樣選擇多、耐磨、耐高溫、易清潔、防水、防潮等特性,已成為櫥柜市場的主導產品,并被越來越多家庭選擇與接受。
Fire-proof board is the most commonly used material in the market at present. Its advantages are fire-proof, moisture-proof, wear-resistant, oil-resistant, easy to clean, and more varieties. Fire-proof board has become the leading product in the cabinet market because of its brilliant color, many patterns, wear resistance, high temperature resistance, easy cleaning, waterproof, moisture-proof and other characteristics, and has been chosen and accepted by more and more families.
優質防火板的特點有:
The characteristics of high quality fireproof boards are:
1、圖案很清晰透徹、效果較逼真、立體感較強。
1, the pattern is clear and penetrating, the effect is more realistic, and the three-dimensional feeling is stronger.
2、版面沒有任何色差。
2, there is no color difference in the layout.
3、表面平整且光滑、較耐磨。
3. The surface is smooth and smooth.

一、 裝飾板表面開裂產生的原因:
First, the reasons for the surface cracking of decorative panels are:
1、 樹脂反應過嫩,分子太小
1, the resin is too tender, and the molecule is too small.
2、 樹脂固化不完全
2. Incomplete curing of resin.
表層膠膜紙含膠量太高解決的方法:
The way to solve the problem of too high glue content in surface adhesive paper is:
1、 不合格的樹脂停止使用
1, disqualified resin stop use.
2、 適當提高熱壓溫度或延長熱壓時間
2, increase the hot pressing temperature or extend the hot pressing time.
3、 控制表層膠膜紙的含膠量。
3, control the glue content of the surface film paper.
二、 裝飾板分層產生的原因:
Two, the reasons for layering of decorative panels are:
1、 膠膜紙揮發物含量太低,膠膜紙在干燥時局部樹脂固化。
1, the volatile content of adhesive film is too low, and the adhesive film is cured when drying.
2、 膠膜紙樹脂含量不夠
2. The resin content of adhesive film is not enough.
3、 壓力過低或熱壓時間不夠。
3, pressure is too low or hot pressing time is not enough.
 
膠膜紙之間有雜物解決的方法:
There is a way to solve the problem of debris between plastic films.
1、 控制揮發物含量不要過低,干燥溫度不要過高,時間不要過長、防止樹脂局部固化。
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、 提高膠膜紙含膠量。
2, increase the adhesive content of adhesive paper.
3、 適當提高壓力含延長加熱時間。
3, increase pressure and prolong heating time.
4、 鋪模時注意清楚雜物
4. Pay attention to sundries while laying the mold.
三、 裝飾板翹曲產生的原因:
Three. Causes of warpage of decorative panels:
1、 各種原紙組織成分厚薄不均勻
1. Uneven tissue thickness of all kinds of base paper
2、 膠膜紙含膠量不均勻,各處壓力不一致
2, the adhesive content of film paper is uneven, and the pressure varies everywhere.

壓制過程中保溫后未能進行充分冷卻解決的方法:
The method of insufficient cooling after heat preservation is solved:
1、 各種原紙應符合工藝要求
1, all kinds of base paper should meet the technological requirements.
2、 保持樹脂濃度均勻,調整擠壓輥軸的間隙3、 冷卻到50度以下在進行卸壓。
2. Keep the resin concentration uniform, adjust the clearance of the extrusion roll shaft 3, and cool to below 50 degrees for pressure relief.
防火板是牛皮紙原紙經過三聚氰胺與酚醛樹脂的浸漬工藝,高溫高壓而成,防火板是否開裂主要看封邊與防火板壓貼 。
Fire-proof board is made of kraft base paper impregnated by melamine and phenolic resin under high temperature and pressure. Whether the fire-proof board cracks depends mainly on the sealing edge and the pressing of the fire-proof board.
飾面防火板施工安裝時,在運到現場后,應用干毛巾擦去浮塵,保持防火板的清潔。 所有飾面防火板都應該放平,底部和面部各放一張基材板,這樣可使板材保持平整,不要豎著放,這樣就可以防止面板開裂、起翹。選擇合適的防火板厚度,正確的施工。
When decorative fireproof board is constructed and installed, dry towel should be used to wipe off floating dust and keep the fireproof board clean after it arrives at the scene. All decorative fire-proof panels should be laid flat, with a base plate on the bottom and face, so that the panels can be kept flat, not vertical, so that the panel can be prevented from cracking and warping. Choose the proper thickness of the fireproof board and correct construction.
