聚氯乙烯胶泥(以下简称胶泥)于1966年首次在太钢初轧厂钢坯库屋面应用到现在已经十八年。屋面不渗不漏,胶泥接缝仍有弹性。胶泥是属于高分子防水材料,都有老化的趋势,如出现老化膜之后,便无法消除。老化膜是胶泥老化在其外观上的一种表现特征。所以通过对胶泥的老化性能研究,可以认识和掌握胶泥的老化规律性,并利用这种规律,采取恰当的防护措施,延长胶泥的使用寿命。胶泥老化是指它在屋面防水工程上,承
Polyvinyl chloride cement (hereafter referred to as cement) was first applied to the steel billet roof of TISCO’s early rolling mill in 1966 and has now been used for 18 years. The roof is impermeable and the clay joints are still flexible. Mastic is a polymer waterproof material that has a tendency to age. If an aging film appears, it cannot be eliminated. Aging film is a performance feature of cement aging in its appearance. Therefore, by studying the aging properties of cement, it is possible to recognize and master the aging regularity of cement, and to take advantage of this rule and take appropriate protective measures to extend the service life of cement. Cement aging means that it is on the roof waterproofing project.
