哪种彩钢板使用寿命更久


彩钢板涂料(涂料)品种(实际使用寿命远比美观寿命长)1:PE(一般聚酯),美观寿命7-10年,盐雾试验周期480h,使用量最大,耐久性一般,主要用于一般工业厂房、仓储物流。仓库,机械加工厂;2:SMP(硅改性聚酯),漂白。光亮寿命8-12年,盐雾试验周期600小时,是普通聚酯PE的1.25倍。


彩钢板涂层坚硬,耐磨,不易粉碎。适用于风沙、铁矿、煤矿等恶劣地区。涂料成本为350元/吨3:HDP:高耐久性聚酯,15年质量保证,720小时盐试验周期,是聚酯的1.5倍,具有良好的耐久性和高性价比。涂料成本仅高于普通聚酯。酯类700元/吨。
PVDF氟碳聚偏氟乙烯20年质量保证,盐雾试验周期720小时,是普通聚酯的两倍,色板王、抗紫外线、耐酸碱能力很强,国家重点工程(永久工程、高铁站、体育馆等)一般采用的涂料成本仅比普通聚酯2340元/吨高耐久性聚酯彩钢板和氟碳彩钢板高。有色金属运动、钢厂、电厂、化工厂等高污染行业和地区),沿海高盐雾、高紫外线地区美好生活。
涂料从失光到变色的时间(不同的环境和职业对美观寿命也有一定的影响),实际使用寿命比美观寿命长得多。使用寿命包括:涂层的光泽损失<涂层变色<涂层粉末化<涂层开裂<涂层起泡<白锈(涂层腐蚀)<红锈(钢板)。腐蚀)<钢板穿孔<钢板损耗效应。
Yellow Stone Color Steel Plate Coating (Paint) Varieties (Practical Service Life is far longer than Beautiful Life) 1:PE (General Polyester), Beautiful Life 7-10 years, Salt Spray Test Cycle 480h, the largest usage, durability is general, mainly used in general industrial plant, warehouse logistics warehouse, mechanical processing plant; 2:SMP (Silicon modified polyester), bleaching. Bright life 8-12 years, salt spray experiment period 600 hours, is 1.25 times that of general polyester PE.
 
Coatings are hard, wear-resistant and difficult to pulverize. They are suitable for areas with severe wind and sand, iron ore and coal mining. Coatings cost is 350 yuan/ton 3:HDP: high-durability polyester with 15-year quality guarantee and 720 hours salt spray test cycle, which is 1.5 times of polyester with good durability and high performance-price ratio. Coatings cost is only higher than general polyester. Esters cost 700 yuan/ton.
 
PVDF fluorocarbon-polyvinylidene fluoride 20 years of quality assurance, salt spray test cycle 720 hours, is twice the general polyester, color board king, anti-ultraviolet, acid and alkali resistance is very strong, only the cost of paint than the general polyester 2340 yuan/ton high-durable polyester color steel plate and fluorocarbon color steel plate are generally used in national key projects (permanent construction, high-speed railway station, gymnasium, etc.). Non-ferrous metal exercise, steel works, power plants, chemical plants and other highly polluting occupations and areas), coastal high salt fog, high ultraviolet area beautiful life.
 
The years from gloss loss to discoloration of coatings (different environments and occupations also have certain effects on beautiful life), so the useful life in practice is much longer than that of beautiful life. The useful life includes: gloss loss of coatings < discoloration of coatings < powdering of coatings < cracking of coatings < foaming of coatings < white rust (corrosion of coatings) < red rust (steel plate). Corrosion) < steel plate perforation < steel plate loss effect.
