Everyone knows that the cracked wooden door will directly lead to the sound insulation of the house, and the airtightness and aesthetics will be worse. Why do some wooden doors have problems such as cracking and deformation? Although the cracking of the wooden door is congenital, it is not impossible. Avoid it, so it is necessary to understand this knowledge before purchasing it.
1. The joint is cracked, that is, the crosspiece and the vertical gear or the joint with the door core board is cracked:
Insufficient cloth or poor glue quality at the junction;
The flatness of the joint is less than 80%, because the gap is too large, the glue does not work;
The relative humidity of the two components connected is greater than 2% or the solid wood humidity is greater than 12%.
2. The component (wood board) cracks itself:
There is no drying treatment before wood processing. The moisture content of the core of the plate is too high, and the surface is dry. Due to the influence of ambient temperature and humidity, the water will evaporate, causing cracking.
3. Reasons for door panel deformation:
The moisture used in processing is too high;
The paint is not closed enough;
The processing structure is unreasonable.
