如何正確選用彩涂板？

How to choose the color coating board correctly?

正確選擇彩涂板應(yīng)考慮建筑物所處的自然環(huán)境、使用環(huán)境、設(shè)計年限、結(jié)構(gòu)特點(diǎn)，來選擇與之相匹配的鋼種、規(guī)格、鍍層及涂層等。建筑師、工程業(yè)主及加工方考慮的是建筑物的安全性能（耐沖擊、抗震、防火、抗風(fēng)壓、抗雪）、居住性能（防水、隔音、隔熱）、耐久性能（耐污染、耐久、外觀保持性）、經(jīng)濟(jì)性（成本低、易加工、易維護(hù)、易更換）等。彩涂鋼板的性能要求主要有材料的力學(xué)性能（抗拉強(qiáng)度、屈服強(qiáng)度、延伸率）、鍍層性能（鍍層種類、鍍層厚度和鍍層附著力）和涂層性能（涂料品種、顏色、光澤、耐久性能、加工性等）。其中抗風(fēng)、抗沖擊、抗雪、抗震等都和材料的力學(xué)性能有關(guān)，當(dāng)然也和彩色壓型鋼板的波形、鋼板的厚度、跨度、檁距有關(guān)，如果選擇合適的彩涂鋼板再配合適當(dāng)?shù)膲盒弯摪逶O(shè)計，既能滿足建筑物的安全系數(shù)又能降低工程造價。而材料的耐久性、加工性能及外觀保持性則大部分由涂層和鍍層的耐久性決定。

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

對底漆的選擇來說，最重要的因素有兩條，其一考慮底漆和面漆以及基板的附著力，其二就是底漆提供涂層大部分的耐腐蝕性能。從這個角度看，環(huán)氧樹脂是不二選擇。如果考慮柔韌性、考慮耐紫外線的話，也可以選擇聚氨脂底漆。

▎ 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

對背面涂層來說，最正確的選擇就是如果彩涂鋼板使用狀態(tài)是單板的話，選擇兩層結(jié)構(gòu)，即一層背面底漆，一層背面面漆。底漆和正面相同品種，面漆選擇一層淺顏色（如白色）的聚酯。如果彩涂鋼板使用狀態(tài)是復(fù)合或夾心板的話，背面涂上一層粘接性和耐蝕性都優(yōu)秀的環(huán)氧樹脂就行。

▎ 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

目前現(xiàn)在還有很多功能性彩涂鋼板，如抗菌彩涂、抗靜電彩涂、隔熱彩涂、自潔彩板等。這些產(chǎn)品的開發(fā)是以滿足用戶特殊需求為目的的，但是有時侯不能兼顧彩涂產(chǎn)品其他性能。因此，用戶選擇功能性彩涂鋼板時一定要明確自己的真正需求。

▎ 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.
