Changsha thin fireproof coatings

The coating thin fireproof coatings Fire Research Institute of Ministry of Public Security Hubei The fire protection properties of the steel structure of petrochemical enterprises in 1992 successfully developed a new type of fireproof coatings, filling the domestic blank outdoor fireproof paint. The coating series a high inorganic compound intumescent fire retardant coating, adhesive strength, good fire resistance, resistance to exposure, moisture resistance, excellent acid oil, corrosion resistance, weather resistance freezing and thawing, widely used in petrochemical enterprises outdoor steel fire protection structures. A note performance indicators (based on GB14907-2002 [fireproof coatings]) Appearance and color: gray wet heat resistance (h): 504 state in the container: uniformly thick fluid state, without caking. Freeze-thaw cycle resistance (times): 15 Surface drying time (h): 3 Acid (h): 360 initial drying crack resistance: No crack alkali resistance (h): 360 bond strength (Mpa): 0.25 Resistance salt spray corrosion (time): 30 violent resistance to heat (h): 720 II. Use 1. coating application should have been made rust in steel. Rust treatment, and removal of dust and grease on its surface after. 2. Construction should be taken at least 5's degree. Stir the paint before construction shall, with fighter 0.4-0.6Mpa air pressure sprayer with spray, the first pass basically cover the bottom can, after each time the thickness should not exceed 3mm, head over the basic dry and then spray a second time until a predetermined thickness. Different fire resistance of the desired coating thickness as follows: fire endurance, after h 1.0 1.5 2.0 2.5 3.0 coating thickness, mm 3.0 3.2 4.5 4.8 5.3 3. spray coating surface is uniform granular surface, usually not smooth, as requested When smooth, conducted after the last spraying again. 4. The coating is suitable for outdoor, construction process and prior to drying and curing the coating, the coating should be avoided suffered rain soaked. Shower. III. Storage 1. This product should be within 5-35 degrees Celsius dry warehouse storage, you have to pay the storage period of six months. This product is non-combustible. Non-explosive non-toxic No Corrosion security products, storage and transportation of attention to sealing
