cinnamene การใช้

The article analyze the concrete drying shrinkage mechanism , find the major factors of affecting the drying shrinkage , analyze the lack of shrinkage reducing agent , who be of low molecular weight and line chain , design a new shrinkage reducing agent ? ? shrinkage reducing agent of poly - acrylate . the shrinkage reducing agent of poly - acrylate is mainly composed of crylic acid 、 cinnamene 、 poly - glycol 、 solicitating agent 、 chain transferring agent and activator , which come by these processes of polymerization 、 esterifing and neutralization to form a pectinate polymer , which have a high molecular weight and many poly - oxidative alkenes
