What kind of aspects do you need to identify the quality of the strengthened wooden door? Many people are confused about it. Today, let me analyze for you and purchase the knowledge points of the strengthened wooden door.
It is impossible to judge the inner of the reinforced wooden door from the weight alone. Sometimes the weight of the particleboard is heavier than that of the solid wood. Although the raw material used to make the particleboard is made of broken wood scrap, many adhesives are applied during the production process, and the adhesive occupies a considerable proportion of the material after curing. The result is not light. In addition, due to the difference in the size and thickness of the door leaf and the filler of the door core, it also causes the weight of the wooden door to be different. Therefore, the specific weight is not the most reasonable basis for judgment.
The quality of the strengthened wooden doors is mainly judged from the treatment of the paint surface. Some problems can be seen. Look, pay attention to two points, one is to see if the paint surface is flat, whether there is any pitting. Generally speaking, the good strengthened paint wooden door is in place in the treatment of the paint surface. The second is to see whether the splicing of the wooden door and the groove are handled carefully. The good products and the secondary products are not distinguishable from the large surface, mainly the details.
