1、三聚氰胺压贴厂工艺标准

建议压贴时间：25-40 秒左右，可根据季节和环境温度环境调整。

压贴温度：185℃-205℃，根据工厂环境、板材厚度不同调整压机上下板温度。

压机压力：16MPa-18MPa，不能低于 12MPa

2、纸张选择

建议选取质量好的三聚氰胺浸渍胶膜纸张。价格低廉的三聚氰胺纸甲醛超标，做好的成品衣柜会因三聚氰胺纸甲醛超标产生异味。

3、板材养生

首先，压贴好的精板，冬季应该在压贴厂养生3天，夏季建议5-7天， 降温释放内应力后，方可打包运走。

其次，精板到家具厂拆包后，建议放置 12 小时，使其适应厂区小气候后再开料。

贴面厂压贴线最好配备晾板线，以利于降温。没有晾板线的，应延长养生时间。在钢制托架上养生。

4、包装

建议精板打包每件不大于 50 张，打包张数过多，由于包装垫方不对齐，或重力等因素，使得板中 内应力向一个方向释放，整体形成一个方向弯曲形变。 

5、存放

精板存放时，要保持地面水平、上下包装垫方处于同一垂直线。49尺板垫方不少于5条，48尺垫方不少于4条。

潮湿地区、潮湿季节，当天开料剩下的精板要做缠绕膜包覆。

6、开背板槽

建议开槽距离半边不小于 10 公分，如果槽位太靠边，内应力不均匀，容易形变。

建议钻孔距离背板槽距离不小于 5 公分，降低形变可能性。

7、封边带选择建议选择表底同色的封边带，廉价封边带打磨后会出现色差。

8、内应力释放不均匀后果

1）板材本身产生形变

2）板材本身形变小，但开背板槽容易，改变内应力，容易形变

3）板材形变后，工厂加工时，钻孔精度产生误差，导致板材安装时产生咬合不齐，影响成品效果。

Spanish brand BORONO OSB instruction manual

1. Process standard of melamine paste factory

Recommended pressing time: About 25-40 seconds, which can be adjusted according to season and ambient temperature.

Sticking temperature: 185 ℃ - 205 ℃, adjust the temperature of the upper and lower plates of the press according to the factory environment and plate thickness.

Press pressure: 16mpa-18mpa, not less than 12MPa

2. Paper selection

It is suggested to select melamine impregnated film paper with good quality. The formaldehyde of cheap melamine paper exceeds the standard, and the finished wardrobe will have peculiar smell due to the excessive formaldehyde of melamine paper.

3. Plate curing

First of all, the pasted fine plate should be kept in the paster factory for 3 days in winter and 5-7 days in summer. It can be packed and transported after cooling and releasing internal stress.

Secondly, after unpacking the refined board in the furniture factory, it is recommended to place it for 12 hours to adapt to the microclimate of the plant before cutting.

The pressing line of the veneer factory should preferably be equipped with an air drying line to facilitate cooling. If there is no drying line, the curing time shall be extended. Curing on steel bracket.

4. Packing

It is suggested that each piece of fine plate should not be more than 50 pieces, and the number of pieces packed is too large. Due to the misalignment of packing cushion, or gravity and other factors, the internal stress in the plate is released in one direction, forming a bending deformation in one direction as a whole.

5. Store

During the storage of fine plates, keep the ground level and the upper and lower packing pads in the same vertical line. There shall be no less than 5 pieces of 49 foot plate cushion and no less than 4 pieces of 48 foot cushion.

In wet areas and wet seasons, the remaining fine plates cut on the same day shall be wrapped with winding film.

6. Back plate slot

It is recommended that the slotting distance should not be less than 10 cm. If the slot is too close to the side, the internal stress is uneven and easy to deform.

It is recommended that the distance between the drilling hole and the back plate groove shall not be less than 5cm to reduce the possibility of deformation.

7. It is recommended to select the edge banding belt with the same color at the bottom of the table. There will be color difference after grinding the cheap edge banding belt.

8. Consequences of uneven internal stress release

1) The plate itself deforms

2) The deformation of the plate itself is small, but it is easy to open the back plate slot, change the internal stress and deform easily

3) After the plate is deformed, the drilling accuracy error occurs during factory processing, resulting in bite during plate installation

Uneven, affecting the effect of finished products.
