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.
