冬季低温蓝球场施工难题怎么解决

?? ?发布时间:2020-03-03
      冬季随着气温降低,用于硅PU的催化活性降低,温度低于10℃,基本不起催化作用。因聚氨酯有较好的稳定性、耐化学性、回弹性和力学性能等优点,现广泛应用于不同领域,如防水涂料、塑胶跑道(硅PU)、工程机械防腐等。但也存在冬天时,成胶时间长,施工难度大等问题。成胶受温度的影响,温度越低,成胶时间越长。因此,行业内都会选择在聚氨酯原料中添加催化剂(有机锡)。
1、防水涂料
目前,国内以单组份涂料为主,不同企业,解决问题的方法不同。部分企业会搭配胺类的催化剂使用,但该方法存在储存风险;部分企业是后添加助剂(扩链剂),但需要施工时添加,会增加工人操作工序。

2、蓝球场
主要增加传统催化剂(有机锡)的用量来解决问题,但效果不佳。

3、工程机械防腐
常用的两种方法是烘烤和添加快速固化剂。但烘烤的方法受机械制品大小的限制而快速固化剂,价格高,性价比低。州优润低温高效快干催化剂WS2。
针对目前行业存在的问题,亚博ag真人体育紧贴市场需求,为客户提供一款单组分低温高效环保催干剂WCAT-WS2/WCAT-WS8。同时,防水涂料行业可以搭配我司的厚涂快干剂YRFS-A/B;塑胶跑道行业可选择厚涂快干剂YRHT-01。

WCAT-WS2/WS8亚博ag真人特点
1、低粘态可流动时间长,有效减少气泡和鼓包;固化后表面镜面光亮,而T-12固化后表面亚光失色。
2、催化后期材料实干迅速。
3、 冬季低温下表干实干快,有效提高低温条件下的成胶速度,缩短施工工期。
4.、材料环保。
