板面局部有白花

　　產(chǎn)生原因：表層紙含膠量不足或干燥中局部樹脂固化；表層紙揮發(fā)物含量過低；熱壓式壓力不均勻；忖墊材料無彈性；不銹鋼板表明不平；樹脂反應(yīng)過老，分子太大，樹脂流動(dòng)性大。

　　解決方法：提高表層紙樹脂含量或控制干燥溫度，防止局部樹脂固化；提高表層紙的揮發(fā)物含量；檢修熱壓機(jī)，改進(jìn)加壓面的均勻性；定期更換忖墊材料；不銹鋼板定期拋光；樹脂應(yīng)分析檢驗(yàn)，不合格指標(biāo)要求時(shí)停止使用。

　　There are some white flowers on the surface

　　Causes: insufficient glue content of surface paper or local resin curing in drying; The volatile content of surface paper is too low. Hot pressing type pressure is not uniform; Gasket material inelastic; Stainless steel plate shows uneven; Resin reaction too old, too large molecules, resin fluidity.

　　Solution: increase resin content of surface paper or control drying temperature to prevent local resin curing; Increase the volatile content of surface paper; Repair the hot press, improve the uniformity of the pressure surface; Regular replacement of gasket material; Stainless steel plate regularly polished; Resin should be analyzed and tested, discontinue use when unqualified indicators are required.

　　板面有濕花（水汽），邊緣較為嚴(yán)重

　　產(chǎn)生原因：浸膠紙干燥后揮發(fā)物含量太高；印刷木紋的油墨或染料所用的溶劑不合適；浸膠干燥后的膠膜紙吸濕（回潮）。

　　解決方法：降低浸膠紙干燥后的揮發(fā)物含量；調(diào)換油墨（染料）用的溶劑；注意膠膜紙的存放，一般可用塑料布遮蓋；

　　There are wet flowers (moisture) on the board surface with severe edges

　　Causes: the volatile content of immersion paper is too high after drying; Inks or dyes used in printing wood grain are not suitable solvents; After soaking and drying, the film paper is hygroscopic (moisture return).

　　Solution: reduce the volatile content of the paper after drying; Change ink (dye) with solvent; Pay attention to the storage of film paper, generally can be covered with plastic cloth;

　　防火板表面開裂

　　產(chǎn)生原因：樹脂反應(yīng)過嫩，分子太??；樹脂固化不完全；表層膠膜紙含膠量太高。

　　解決方法：不合格的樹脂停止使用；適當(dāng)提高熱壓溫度或延長(zhǎng)熱壓時(shí)間；控制表層膠膜紙的含膠量。

　　Cracked surface of decorative board

　　Causes: resin reaction is too tender, the molecule is too small; Resin curing is not complete; Surface film paper contains too much glue.

　　Solution: stop using unqualified resin; Appropriately increase the hot pressing temperature or prolong the hot pressing time; Control the glue content of surface film paper.

　　裝飾板分層

　　產(chǎn)生原因：膠膜紙揮發(fā)物含量太低，膠膜紙?jiān)诟稍飼r(shí)局部樹脂固化；膠膜紙樹脂含量不夠；壓力過低或熱壓時(shí)間不夠；膠膜紙之間有雜物。

　　解決方法：控制揮發(fā)物含量不要過低，干燥溫度不要過高，時(shí)間不要過長(zhǎng)、防止樹脂局部固化；提高膠膜紙含膠量；適當(dāng)提高壓力含延長(zhǎng)加熱時(shí)間；鋪模時(shí)注意清楚雜物。

　　Decorative lamination

　　Causes: the volatile content of film paper is too low, the local resin curing of film paper when drying; Resin content of film paper is not enough; Pressure is too low or hot pressing time is not enough; There are sundries between the coated papers.

　　Solution: control volatile content should not be too low, drying temperature should not be too high, time should not be too long, to prevent local curing of resin; Increase the glue content of film paper; Appropriately increase the pressure including prolong the heating time; Pay attention to clear sundries when laying molds.

　　富美家防火板翹曲

　　產(chǎn)生原因：各種原紙組織成分厚薄不均勻；膠膜紙含膠量不均勻，各處壓力不一致；壓制過程中保溫后未能進(jìn)行充分冷卻；

　　解決方法：各種原紙應(yīng)符合工藝要求；保持樹脂濃度均勻，調(diào)整擠壓輥軸的間隙；冷卻到50度以下在進(jìn)行卸壓00。

　　Warping of fumei's fire protection board

　　Causes: the thickness of tissue components of various base paper is not uniform; Film paper glue content is not uniform, the pressure is not consistent; Not enough cooling after heat preservation in the process of pressing;Solution: all kinds of base paper should meet the process requirements; Keep the resin concentration uniform, adjust the clearance of the extrusion roller shaft; Cool to below 50 degrees before pressure relief 00.
