145224-94-8|The Application of MES·H2O in the Construction

       2- (N-morpholine) ethanesulfonic acid monohydrate abbreviated as MES·H2O in English, with CAS 145224-94-8, is an organic compound with molecular formula C6H15NO5S and molecular weight 213.25. MES·H2O (CAS: 145224-94-8) is a biological buffer widely used in laboratory research and development and chemical and pharmaceutical synthesis. In addition, MES·H2O can also be used in concrete crack repair systems. This week, YACOO editor will briefly introduce the preparation method of this concrete crack repair systems.
      The concrete crack repair system consists of four parts: epoxy resin layer 1, thermoplastic sealing layer 2, substrate packaging growth layer 3, and auxiliary heat layer 4;
      The ingredients for the material of plastic sealing layer 2 include: 800-920 parts by weight of foam alkali, 280-320 parts by weight of dimethyl silicone oil, 80-144 parts by weight of sodium carboxymethyl cellulose, 52-86 parts by weight of epoxy soybean oil, 18-36 parts by weight of triethyl citrate, 7-13 parts by weight of diethyl ethanol, 24-56 parts by weight of dimethyl sulfoxide 6-28 parts by weight of 2- (N-morpholine) ethanesulfonic acid monohydrate (CAS: 145224-94-8), 4-28 parts by weight of 1,4-butanediol diglycidyl ether, 5-9 parts by weight of rosin, 26-44 parts by weight of potassium aluminum sulfate, 820-1640 parts by weight of H2O, 34-64 parts by weight of diacetyl tartrate monoglyceride, and 4-22 parts by weight of azodiisobutyronitrile.
      The material of thermoplastic sealing interlayer 2 makes up for the problems of insufficient shear strength, water resistance and freeze-thaw resistance in the actual application of the existing concrete crack inhibitor, and the water resistance and freeze-thaw resistance are better.
