Ensure steel quality from the hardware, allowing users to buy the rest assured with satisfaction. Anticorrosive epoxy powder FBE pipe outer coating is a new coating developed in the last 30 years, the use of electrostatic spraying epoxy powder coated paint, a film. The coating is applied with a simple operation, clean, good impact resistance and bending performance coatings, and high temperature performance. Features: fast curing, curing time is short, high coating efficiency, suitable for assembly line. Excellent mechanical and physical properties. Excellent corrosion resistance, acid, alkali, salt, oil, and water. Can play a long-lasting effect of corrosion in a wide temperature range. Coating standard SY / T0315-97 and CAN / CSA-Z245.20-98 technical requirements. Construction Description: Application Method: 40 ~ 120KV high voltage electrostatic spraying. Recommend Thickness: ordinary level 300 ~ 400um, to strengthen the level 400 ~ 500um. Theoretical amount: ordinary level 0.42 ~ 0.56 kg / m2 to strengthen the level 0.56 ~ 0.70 kg / m2 Surface treatment: sand or rust more than Sa2.5 level, anchor pattern depth of 50 ~ 80um. Preheat the workpiece: general use frequency heating, the workpiece temperature controlled within the range of 220 ℃ ~ 240 ℃, should not exceed 260 ℃. Spray: regulation and the workpiece, the coating reaches a specified thickness. Quenching time: 230 ℃, the time from spraying to quench coating of not less than 90 s cooling: cooling down to below 95 ℃, surface inspection. Repair leak point: after the leak is detected, roughened, and the use of our heavy-duty liquid epoxy coating SLH07 repair. The powder coating product is applied on top of the preheating of the workpiece, the use of waste heat curing, generally does not require post-baking. But in the wall is too thin piece outside temperature is too low or the need to consider additional heat curing. We always uphold the "pursuit of excellence, quality-oriented" business philosophy and "customer first, Dexing factory" business purposes, committed to building management-based, customer-centric, technology as the guide to quality as the lifeline optimization of business, the company is willing to be your long-term partner, we sincerely welcome your arrival!
