JY型混凝土养护剂是以聚乙烯为主要原料,加入适量的表面活性剂、成膜剂、稀释剂而成的水溶性材料。它用于混凝土浇筑成型后,喷洒在混凝土表面,使其形成一层密实的薄膜,从而有效地阻止混凝土内部多余水分的过早蒸发,达到自养护目的。并且养护剂有渗透和固化作用,能向混凝土表面下渗透1～3mm,形成一个较坚硬的表面层,进一步提 JY concrete curing agent is based on polyethylene as the main raw material, adding an appropriate amount of surfactant, film-forming agent, thinner made of water-soluble materials. It is used for concrete pouring, sprayed on the concrete surface, making it a dense film, which effectively prevent premature evaporation of excess moisture inside the concrete to achieve self-curing purposes. And curing agent penetration and curing effect, can penetrate the concrete surface 1 ~ 3mm, forming a harder surface layer, to further mention
