Foreword

This standard is not equivalent to the American Society for Testing and Materials standard ASTMC466-2003 "corrosion-resistant chemical curing siliceous clay art condition". The standard in the use of ASTM standards, product technical indicators in addition to the full by the United States ASTMC466 standards, but also increased the state Standard GB 50212-2002 "building construction and acceptance of anticorrosive engineering" required in the final set time, pickling stability of two indicators, So not only in line with US standards ASTMC466 technical requirements, but also with the national standard GB 50212's requirements. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Non-metallic chemical equipment Standardization Technical Committee (SAC/TC162) centralized. This standard was drafted. Tianhua Institute of Chemical Machinery and Automation, Henan Qinyang Shennong clay Co., Jiangxi Pingxiang City, Long Industrial Co., Ltd. The main drafters of this standard. Chen Zheng, Zhang Branch, Guo Yu root, sending and receiving Luo, Hou Yibing. Corrosion-resistant chemical curing siliceous clay technical conditions

1 Scope

This standard specifies the chemical and anti-corrosion member bonded to the silicon corrosion chemical curing mastic technical requirements. This standard applies to chemical corrosion cured siliceous clay.

3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 Corrosion-resistant chemical curing siliceous clay chemicalysettingsilicatechemical-resistantmortars Silicate adhesive powder mixture, a curing agent and a chemically inert filler consisting of a single package, mixed with tap water at room temperature And; or in liquid silicates or silica binder, a powdered mixture with a curing agent and chemically inert filler formed of mixing at room temperature Spreadable like clay, and because the curing agent and a binder from a chemical reaction for curing cement. Category 4 4.1 corrosion chemical curing siliceous cement its packaging products divided into two types, namely, single-component solid clay and solid-liquid two-component Clay. 4.1.1 solid single component is a mixture of the powdered cement binder, a curing agent and chemically inert filler, and after adding water mixing shape Spreadable into clay. 4.1.2 is a solid-liquid two-component mastic adhesive after the liquid, powder curing agent and chemically inert filler mixture, mixing formed Apply clay. 4.2 corrosion chemical curing siliceous cement their type of binder divided into three categories, namely sodium type, potassium silicate and silica type type.

5 Chemical composition

Corrosion-resistant chemical curing siliceous clay used in the curing agent should be able to chemically react with acidic siliceous binder material, or with silica React chemically to form an insoluble silicate gels basic compound. The choice of filler should not be in contact with corrosive chemical media, fillers The range is determined by the manufacturer.

6 Physical and Chemical Properties

Siliceous clay corrosion chemical cure physical and chemical properties shall be in accordance with Table 1. ......
