一种新型混凝土养护剂,在桂林市金桂化工厂研制成功,并投入了批量生产。这种养护剂是以聚乙烯下脚料、松香为原料,经高温反应而成。性能好,使用方便。用水稀释后,喷涂在初凝的混凝土表面,即可满足养护条件,改变了过去的浇水、遮物等传统工艺。使用该产品,每平方米养护成本仅0.25元。养护期过后,养护剂自身自行脱落,不影响建筑物表面装修。解决了一些混凝土建筑如渠道的坡面、隧道的顶面难以养护的课题。对 A new type of concrete curing agent was successfully developed at Guilin Jingui Chemical Plant and put into mass production. This curing agent is made of polyethylene waste and rosin as raw materials and reacted at high temperatures. Good performance, easy to use. Diluted with water and sprayed on the concrete surface of the initial setting, the conditions for curing can be satisfied, and the traditional techniques such as watering and covering are changed. With this product, the maintenance cost per square meter is only 0.25 yuan. After the curing period expires, the curing agent will fall off on its own without affecting the surface decoration of the building. Solved the problem that some concrete buildings, such as the slope of the channel, the top surface of the tunnel difficult to maintain. Correct
