Introduction of GB 50212-2002

1 General Provisions 1.0.1 This specification is formulated with view to improving the construction level of anticorrosive engineering of buildings, strengthening the quality acceptance control during construction process of anticorrosive engineering and ensuring the anticorrosive engineering quality of buildings and structures. 1.0.2 This specification is applicable to the construction and acceptance of anticorrosive engineering constructed, renovated or extended buildings and structures. 1.0.3 The materials used for construction of anticorrosive engineering of buildings must be accompanied with product quality proof documents, and their quality shall not be inferior to the requirements of the relevant current standards of the nation; where there is no such relevant current standards of the nation, their quality shall meet the requirements of this specification. 1.0.4 The product quality proof documents shall cover the following contents: 1 Product quality certificate and material test report. 2 Quality and technical indexes and test methods. 3 Reinspection report or technical appraisal document. 1.0.5 The materials to be prepared on site must be determined through test, and their mix proportion shall also meet the requirements of Annex A. The mix proportion determined through test shall not be changed at will. 1.0.6 The construction of anticorrosive engineering of buildings must be carried out according to the requirements of design documents. Where it is needed to change design, substitute materials or adopt new materials, the consent of design department is required. 1.0.7 In addition to the requirements of this specification, the construction of anticorrosive engineering of buildings shall also comply with the relevant standards and codes of the nation.   2 Terms 2.0.1 potassium silicate material acid-proof and heat-proof silicate material prepared with potassium silicate aqueous solution as the binder, condensed aluminium phosphate as the curing agent and silicon-aluminum oxides as powder and aggregate by adding a small amount of auxiliary materials 2.0.2 a set of matched coating composite coating composed of various compatible coatings via reasonable combination in such aspects of material selection, structure matching and coating process 2.0.3 tolerant coating ground coating which can be directly applied on the steel base course surface with rusting grade of A or B and still has certain antirust function 2.0.4 self-leveling coating high build coating which presents certain flowing and extending capacity during coating construction, has a at least 300μm dry film thickness of each coating layer, has no construction trace after drying and also has decoration effect 2.0.5 high build coating solvent volatilizing coating with the one-time formed dry film thickness no less than 60μm or chemical reaction (crosslinked) coating with the one-time formed dry film thickness no less than 100μm 2.0.6 glass flake coating high build coating processed with anticorrosive synthetic resin as the main film forming material as well as the specially-treated flake glass, pigments, fillers and additives
