摘要
The NW-3-7 high-temperature clay anti-plumping agent is a new generation of product developed in 1993 by the Binhu Jiufan Group Corporation. According to cation polymer’s function of peridium flocculation, the product uses a small molecular weight of cation organic compound to function as a peridium for a clay surface, thus reducing hydrability, swelling and the dispersion of slurry and stabilizing mineral content of sensitive sandy clay. Such an effect creates a high anti-plumping and anti-sanding
