Corrosion prevention and rust prevention of Integrated Housing steel

集成住所原材料發泡水泥復合板全部規范.規范均應表現科學性.可操作性.有效性和規范性。無機保濕砂漿各部門應看重在管理上做文章，對保溫材料.節能規劃.工程施工.工程檢收.工程保護等環節進行監督管理，做到有章可循，完善準則性保障體系，確保建筑節能作業順利推進。

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.

發泡水泥復合板建筑節能是節能減排作業的重要組成部分，是全國人民一起的責任，政府.職業.企業都應該圍繞努力提高節能功率這一中心開展作業。

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.咱們要考慮涂料的配套是否正確，咱們知道大部分涂料是有機膠狀物質為基料，咱們將涂料每涂一層結成薄膜后，不免會有許多細微的微孔，因而，腐蝕介質會進入腐蝕鋼鐵?，F在咱們觸摸的涂料的施工都不是涂單層而是涂多層，其意圖就是將微孔降低到低極限，底漆和面漆之間應有杰出的適應性。如過氯乙烯漆與磷化底漆或者鐵紅醇酸底漆配套運用才會有很好的作用，卻不能與油性底漆相配套運用。因為過氯乙烯漆含有強溶劑，會損壞底漆漆膜。

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.當然，防腐涂料的底漆，中心漆，面漆有必要配套運用。相關于一般的涂裝要求的構件，并選用手工及動力東西除銹時，可選用兩道底漆兩道面漆的做法。對涂裝要求較高的構件，并選用噴發除銹時，宜選用兩遍底漆，1-2遍中心漆，兩遍面漆的做法，涂層干漆膜總厚度不該小于120μm.150μm.200μm，當然，關于一些需求加劇防腐的部位，可適當增加涂層厚度，20-60μm。關于涂層厚度要均勻，無針孔，接連完好，就可以獲得杰出的防腐防銹作用。

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.要考慮施工條件的可能性，有的合適噴涂，有的合適，有的枯燥成膜等。一般情況下，宜用枯燥，便于噴刷的冷固型涂料。

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.要考慮結構所在的運用條件及選用涂料的范圍一致性，依據腐蝕介質的情況，氣相和液相，濕熱區域或枯燥區域等條件進行選用，關于有酸性介質，可選用耐酸性能較好的酚醛樹脂漆，而相關于堿性介質，應選用耐堿性較好的環氧樹脂漆。

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.
