U 型槽是一次模压成型技术，企口处有耐磨层，槽型浅，底部为圆弧状，不容易藏灰。它的优点是好打理不容易藏灰，铺装效果大气美观。但U型槽是蠕动泵 保定建筑设计 保定网站建设 保定网站制作 保定网络公司 保定办公家具 保定轻钢别墅 模压一次成型的，模压时的压力越大，倒角处基材被压溃产生裂纹，被压溃的部位在地板的使用过程中产生不规则的回弹，使倒角边基材的裂纹进一步加强，导致倒角处的耐磨层一起开裂，连接稳定性相对较差。
U-groove is one-time molding technology. There is a wear-resistant layer at the groove. The groove is shallow and the bottom is arc-shaped, so it is not easy to hide ash. Its advantages are good care, not easy to hide ash, paving effect atmosphere beautiful. However, the U-shaped groove is molded at one time. The greater the pressure during molding, the base material at the chamfer is crushed to produce cracks, and the crushed parts produce irregular springback during the use of the floor, which further strengthens the cracks of the base material at the chamfering edge, resulting in the joint cracking of the wear-resistant layer at the chamfering, and the connection stability is relatively poor
