天气转凉，寒冬将至，胶王公司温馨提醒广大客户，敬请留意PUR热熔胶 (反应型聚氨酯热熔胶) 在冬季使用时的几点注意事项：

首先，在用胶方面的调整，把熔胶系统和涂胶系统的设置温度提高5-10℃，确保胶水在粘合时达到最佳的工作状态。此外，请开启养生房，把做好的产品放到养生房中，要求养生房的温度大于15℃，最佳养生时间为24小时以上。

从产品工艺的角度看，除了上述两点（使用温度和养生环境），生产线的辅助加热系统也要适当开启：

封边

开启板材预热和封边带预热系统，要求板材在涂胶前预热到15℃以上，封边带不低于20℃。

平贴

总则：板材和膜皮在贴合前，最好放入养生房中回暖。

开启板材涂胶前后预热系统，涂胶前板材温度预热到25-35℃之间，涂胶后在贴合时胶面温度保持在25-38℃之间；饰面薄膜在贴合时温度要求高于15℃。

养生：素板贴面养生时间不少于24小时，三聚氰胺板贴面养生时间不少于48小时。具体养生时间可根据养生房的温度和胶水本身的反应速度做适当调整。

包覆

需对线条/型材进行预热，木质基材表面温度不低于25℃，铝材表面温度不低于30℃，并适当增加热风枪，延长胶水的开放时间，确保产品的最佳粘接效果。

胶王公司会一如既往的严把产品质量关，提高合格率，平稳、安全过冬。
