Scope of application edit
1. Modification of polyester felt base elastomer asphalt Waterproof coiled material is applicable to roof and underground waterproof works of industrial and civil buildings. 2. Glass fiber reinforced polyester felt base coiled material is suitable for single layer waterproof of mechanical fixation, but it needs to pass the wind load test.
3. Glass fiber felt based coiled material is suitable for general roof and underground waterproof works with stable structure; 4. Exposed waterproof coiled material with opaque mineral particles as the upper surface isolation material shall be used.
5. The surface isolation material should be fine sand Waterproof coiled material.
Key points of construction edit
1. Base surface treatment: it is required to be dry (moisture content<8%), clean, solid, flat, free of dust and oil stain. The internal and external corners shall be made into arc shape, and the node parts shall be treated in advance;
2. Priming coating: in order to facilitate construction and ensure the quality of coating film, the "Qinglong" CQ110 crack resistant special base treatment agent is used to evenly coat the base layer, and it can be carried out after it is dry (about 6-8h) coating Construction; 3. Coating construction: evenly apply the coating on the base surface with a rubber scraper or a brown brush. The coating of this product is usually carried out in three times, and each time the coating is about 0.5mm thick; When coating, the next coating can be applied only after the previous coating is completely dry (about 6-8h);
4. Make isolation layer: after the coating is dry (about 3 days), lay a layer of non-woven fabric or glass fiber cloth on its surface as the isolation layer (30-50g/m);
5. Reference dosage: paint: 2.3-2.5kg/m (1.5mm thick) base treatment agent: 0.2kg/m
matters needing attention
1. The coating has precipitation, which is normal, and should be stirred when used;
2. The construction temperature should be above 5 ℃. During construction, the air circulation in the construction environment should be smooth;
3. In the process of coating, if bubbles are found, they should be punctured with a needle roller within half an hour. The coating has unique self-healing ability and does not affect the quality of the coating film;
4. During the construction process, the coating should avoid contacting with xylene, gasoline and other agricultural production system solvents [1] 。
Selection method
1. It's better to go to the manufacturer for field investigation. This link is necessary because the production process of this material seems very simple, but it requires many conditions to do a good job. Several key points should be paid attention to when going to the manufacturer for inspection, including technical status of equipment, raw materials (mainly depending on whether asphalt is recycled, SBS and tire base cloth are available), and laboratory.
2. When selecting materials, it is better to consult the salesmen of several manufacturers face to face to verify. Don't think too much about the samples they provide to you. It is better to take the samples they provide to the warehouse of other units to check whether they are consistent.
3. Don't attach too much importance to price. If you really have a problem with funds, you should not blindly ask SBS. You might as well choose some good manufacturers' - 10 grade materials, whose prices may be even lower [2] 。
