Product Introduction ：
FYT-1 improved Waterproof coating (HC-201), a kind of polymer composite, is a national key science and technology promotion project door The relevant personnel prepared for appraisal reach the level of similar products. The product has been tested by the Highway Engineering Testing Center of the Ministry of Communications, and all technical indicators meet the requirements of JT/T575-2005 standard; Comply with JTT041-2000 (Technical Code for Construction of Highway Bridges and Culverts), and adopt special domestic asphalt or Petroleum asphalt As the main raw material, with various surfactants and chemicals auxiliary SBS thermoplastic rubber is used as auxiliary raw material to produce a new composite waterproof coating, which is modified by adding more high molecular polymer resin.
FYT-2 polymer bridge deck waterproof coating (H-C-202) can be used alone or combined with FYT-1 improved waterproof coating for bridge deck waterproofing, which can prevent reinforcement corrosion caused by water leakage of concrete bridge deck and increase the service life of bridge body. The performance indicators of FYT-1 and FYT-2 are evaluated by the Ministry of Construction as domestic levels. The reporter learned from Baotou Transportation Bureau that the construction of Toktor Donghe Section of Provincial Highway 315 will begin in the near future. The starting point of the highway project is located in Tumet Right Banner and Trafigura
Product characteristics: The starting point of the road project is located in the west of Sanyidiu Village, the road at the junction of Tumote Right Banner and Toktor County, along with the provincial highway 315 planned and constructed in Hohhot City, and the end point is in the west of Dengkou Village, Donghe District, connecting with K1800 of Baotou South Ring Road. The road is generally east-west, with a total length of 95.265 kilometers, including 66.191 kilometers of Class I highway and 28.074 kilometers of Class II highway, Another 0.39 km secondary highway connecting line is set, with a design speed of 80 km/h. There are 2 major bridges, 3 medium bridges, 1 separated overpass, 1 toll station and 1 maintenance area along the line. It is estimated that the total investment is 2.489 billion yuan. It is reported that the project will start in April this year and be completed and opened to traffic in August 2019. Within this year, 80% of the subgrade works, 60% of the pavement gravel cushion, and all the bridges and culverts will be completed. The construction of the project is of great significance for promoting the construction of the economic belt along the Yellow River and further promoting the economic and social development of the areas along the line.
1. The construction process is simple. The construction can be done by mechanical spraying or manual painting. The drying is fast and the construction period is short.
2. The waterproof layer is cheap, and generally only needs to be painted three times to achieve waterproof effect.
3. The waterproof layer is firmly bonded with the base course, and the waterproof layer is firmly bonded with the upper asphalt concrete.
Technical indicators:
◆ Main technical indicators (according to JT/T 535-2004 and JC/T975-2005 Waterborne Asphalt Based Waterproof Coatings for Road and Bridge)
Scope of application:
It is suitable for waterproofing works of highway bridges, urban overpasses, bridges and culverts.
Construction, transportation and storage:
1. Preparation of construction tools: Before construction, the mixing bucket, spraying machine or special bristle brush shall be prepared.
2. Base course requirements: the strength of bridge deck and beam concrete shall reach the design mark, and the surface shall be free of loose laitance, peeling, hollowing and serious cracking. The surface flatness shall meet the requirements of bridge specifications. The elevation of the upper opening of the vertical drainage pipe shall be lower than the elevation of the base layer. The drainage outlet must be firmly installed with the base layer without any looseness.
3. The base course shall be clean, dry and free from ponding. 4. Base course treatment: the base surface shall be free of dust, floating ash, impurities, oil stains, etc. Before the waterproof layer is made, the surface can be cleaned by air compressor, water purification, degreasing agent, etc. If there are hard sundries such as concrete and mortar, they should be polished off.
5. Construction steps of waterproof layer: (take three coats as an example)
1) The barreled coating shall be stirred evenly before painting.
2) Before large-area painting, use a small brush to paint the leak twice, and apply waterproof paint three times on the internal corners, and then brush the previous paint on a large area.
3) The second coating can be applied after the previous coating is dried. 4) The second coat of paint shall be applied after the surface is dry.
6. Coating amount: 0.5-1.0kg/m2, coating film thickness is generally 0.6~1.3 mm, and spraying is 0.3 kg/m2.
7. The construction temperature should be 0~35 ℃, and it is not suitable for construction in rainy days and freezing periods.
8. The packaged products are packed in iron drums with lids, each weighing 200kg and 50kg 9. Transportation: The product is harmless and nonflammable, and can be transported by general transportation methods.
10. Storage: The storage period of the product is 6 months, and it should be stored in a warehouse above 0 ℃. In summer, it should be protected from sunlight.
