如何正确选用彩涂板

How to choose the color coating board correctly?

正确选择彩涂板应考虑建筑物所处的自然环境、使用环境、设计年限、结构特点,来选择与之相匹配的钢种、规格、镀层及涂层等。建筑师、工程业主及加工方考虑的是建筑物的安全性能(耐冲击、抗震、防火、抗风压、抗雪)、居住性能(防水、隔音、隔热)、耐久性能(耐污染、耐久、外观保持性)、经济性(成本低、易加工、易维护、易更换)等。彩涂钢板的性能要求主要有材料的力学性能(抗拉强度、屈服强度、延伸率)、镀层性能(镀层种类、镀层厚度和镀层附着力)和涂层性能(涂料品种、颜色、光泽、耐久性能、加工性等)。其中抗风、抗冲击、抗雪、抗震等都和材料的力学性能有关,当然也和彩色压型钢板的波形、钢板的厚度、跨度、檩距有关,如果选择合适的彩涂钢板再配合适当的压型钢板设计,既能满足建筑物的安全系数又能降低工程造价。而材料的耐久性、加工性能及外观保持性则大部分由涂层和镀层的耐久性决定。

The correct selection of color coating plate should consider the natural environment, use environment, design life, structural characteristics of the building, to choose the matching steel types, specifications, coating and coating. The architect, the project owner and the processor are the consideration of the safety performance of the building (impact resistance, seismic, fire prevention, wind pressure resistance, snow resistance), residential performance (waterproof, sound insulation, heat insulation), durability (pollution resistance, durability, appearance maintenance), economy (low cost, easy to process, easy to maintain, easy to replace), etc. The performance requirements of color-coated steel plate mainly include the mechanical properties of the material (tensile strength, yield strength, elongation rate), coating properties (coating type, coating thickness and coating adhesion) and coating properties (coating variety, color, luster, durability, processability, etc.). Among them, wind resistance, impact resistance, snow resistance, earthquake resistance are related to the mechanical properties of the material, of course, and color pressure steel plate waveform, steel plate thickness, span, purlin distance, if the choice of appropriate color coated steel plate with the appropriate pressure steel plate design, can meet the safety factor of the building and can reduce the project cost. The durability, processing performance and appearance retention of materials are mostly determined by the durability of coating and coating.

底漆

对底漆的选择来说,最重要的因素有两条,其一考虑底漆和面漆以及基板的附着力,其二就是底漆提供涂层大部分的耐腐蚀性能。从这个角度看,环氧树脂是不二选择。如果考虑柔韧性、考虑耐紫外线的话,也可以选择聚氨脂底漆。

primer

For the choice of primer, the most important factors are two, one considers the primer and topcoat and the adhesion of the substrate, the other is that the primer provides most of the corrosion resistance of the coating. From this point of view, epoxy resin is the best choice. If you consider flexibility and UV resistance, you can also choose a polyurethane primer.

背漆

对背面涂层来说,最正确的选择就是如果彩涂钢板使用状态是单板的话,选择两层结构,即一层背面底漆,一层背面面漆。底漆和正面相同品种,面漆选择一层浅颜色(如白色)的聚酯。如果彩涂钢板使用状态是复合或夹心板的话,背面涂上一层粘接性和耐蚀性都优秀的环氧树脂就行。

back paint

For the back coating, the most correct choice is that if the color coated steel plate use state is a single plate, choose two layers of structure, that is, a layer of back primer, a layer of back surface paint. Primer and front of the same variety, face paint choose a layer of light color (such as white) polyester. If the color-coated steel plate is used in a composite or sandwich plate, the back is coated with an epoxy resin with excellent adhesion and corrosion resistance.

功能性彩板

目前现在还有很多功能性彩涂钢板,如抗菌彩涂、抗静电彩涂、隔热彩涂、自洁彩板等。这些产品的开发是以满足用户特殊需求为目的的,但是有时侯不能兼顾彩涂产品其他性能。因此,用户选择功能性彩涂钢板时一定要明确自己的真正需求。

functional color board

At present, there are many functional color coating steel plates, such as antibacterial color coating, anti-static color coating, heat insulation color coating, self-cleaning color plate, etc. The development of these products is to meet the special needs of users, but sometimes can not take into account other performance of color coating products. Therefore, users choose functional color coated steel plate must be clear about their real needs.
