タイトルまたは説明

The oil-soluble polyurethane grouting material is a kind of chemical grouting material which is composed of a complex polymerized polyol and a polyisocyanate to form a terminal containing isocyanato groups. The material immediately after the reaction of water to produce gas, the volume of expansion and produce a water insoluble and have a certain strength of the foam, not only waterproof plugging, more suitable for reinforcement reinforcement. The reaction speed, construction convenience, in the rescue can play an immediate role. Expansion rate, do not shrink, the normal slurry and water reaction can form ****0 times the foam, which can further enrich the gap, play a waterproof plugging effect. Areas that are in contact with drinking water can also be used with environmental performance.
