Corrosion prevention and rust prevention of Integrated Housing steel

集成住所原材料发泡水泥复合板全部规范.规范均应表现科学性.可操作性.有效性和规范性。无机保湿砂浆各部门应看重在管理上做文章，对保温材料.规划.工程施工.工程检收.工程保护等环节进行监督管理，做到有章可循，完善准则性保障体系，确保建筑作业顺利推进。

All specifications for foamed cement composite panels of raw materials for integrated housing shall be scientific, operational, effective and normative. All departments of inorganic moisturizing mortar should pay more attention to the management of thermal insulation materials, energy-saving planning, engineering construction, engineering inspection, engineering protection and other aspects of supervision and management, so as to have rules to follow, improve the normative guarantee system, to ensure the smooth progress of building energy-saving operations.

发泡水泥复合板建筑是减排作业的重要组成部分，是全国人民一起的责任，政府.职业.企业都应该围绕努力提高功率这一中心开展作业。

Foam cement composite board building energy conservation is an important part of energy conservation and emission reduction operations, is the responsibility of the people of the country, the government, occupation, enterprises should focus on efforts to improve energy-saving power of this center to carry out operations.

1.咱们要考虑涂料的配套是否正确，咱们知道大部分涂料是有机胶状物质为基料，咱们将涂料每涂一层结成薄膜后，不免会有许多细微的微孔，因而，腐蚀介质会进入腐蚀钢铁。现在咱们触摸的涂料的施工都不是涂单层而是涂多层，其意图就是将微孔降低到低极限，底漆和面漆之间应有杰出的适应性。如过氯乙烯漆与磷化底漆或者铁红醇酸底漆配套运用才会有很好的作用，却不能与油性底漆相配套运用。因为过氯乙烯漆含有强溶剂，会损坏底漆漆膜。

1. We should consider whether the matching of coatings is correct or not. We know that most coatings are based on organic colloidal substances. When we coat the coatings into thin films, there will inevitably be many tiny pores. Therefore, the corrosive medium will enter the corrosive steel. Now we touch the coating is not the construction of a single layer but a multi-layer coating, its intention is to minimize the porosity between the primer and top coat should be outstanding adaptability. If the PVC paint and phosphating primer or iron red alkyd primer matching application will have a good effect, but can not be matched with oily primer application. Because perchloroethylene paint contains strong solvents, it will damage the primer paint film.

2.当然，防腐涂料的底漆，中心漆，面漆有必要配套运用。相关于一般的涂装要求的构件，并选用手工及动力东西除锈时，可选用两道底漆两道面漆的做法。对涂装要求较高的构件，并选用喷发除锈时，宜选用两遍底漆，1-2遍中心漆，两遍面漆的做法，涂层干漆膜总厚度不该小于120μm.150μm.200μm，当然，关于一些需求加剧防腐的部位，可适当增加涂层厚度，20-60μm。关于涂层厚度要均匀，无针孔，接连完好，就可以获得杰出的防腐防锈作用。

2. of course, anticorrosive primers, central lacquers and topcoat are necessary. Two primers and two topcoats are optional for components that are required for general painting and for rust removal by hand and power. When spraying and removing rust, it is advisable to use two times primer, 1-2 times central paint and two times top coat. The total thickness of dry coating film should not be less than 120 micron. 150 micron. 200 micron. Of course, the coating thickness can be increased appropriately in some areas where the demand for corrosion protection is increasing. As for the coating thickness to be uniform, no pinholes, good connectivity, you can obtain outstanding anti-corrosion and anti-rust effect.

3.要考虑施工条件的可能性，有的合适喷涂，有的合适，有的枯燥成膜等。一般情况下，宜用枯燥，便于喷刷的冷固型涂料。

3., we should consider the possibility of construction conditions. Some are suitable for spraying, some are suitable, some are dry and film-forming. Under normal circumstances, it is advisable to use dry, easy to spray cold solid coatings.

4.要考虑结构所在的运用条件及选用涂料的范围一致性，依据腐蚀介质的情况，气相和液相，湿热区域或枯燥区域等条件进行选用，关于有酸性介质，可选用耐酸性能较好的酚醛树脂漆，而相关于碱性介质，应选用耐碱性较好的环氧树脂漆。

4. Considering the application conditions of the structure and the consistency of the range of the coatings to be selected, according to the conditions of corrosive medium, gas and liquid phase, humid and hot area or dry area, etc., the phenolic resin paint with better acid resistance can be selected for the acidic medium, and for the alkaline medium, the phenolic resin paint with better alkaline resistance should be selected. Epoxy resin paint.
