KLZ-01 For cement grinding aids, new raw materials

This product is based on polyol molecules, molecular modification. By accessing functional groups with strong complexing ability, the dispersion of products is improved, and the hydration ability of synthetic products on cement is improved. Direct single use or compound of other materials as grinding aids can ensure the strength requirements of cement while ensuring grinding aids. This product can reduce the dependence of grinding aids on high-priced chemical raw materials (such as triethanolamine), and at the same time has no adverse effect on the strength of cement in the later stage, and can also ensure the performance of concrete in the later stage. The product is chlorine-free, non-flammable green product.
