First, GCL (GCL) Note: 1, waterproof blanket of storage should be waterproof, moisture, strong sunlight prolonged sun exposure. Floors should be taken during storage overhead paving method, transported to the site of waterproof blanket should be used the same day. 2, during the next process or an adjacent construction, has completed the process of coping waterproof blanket properly protected, without any man-made damage. 3, should avoid wearing spiked shoes, high heels stepping on the GCL; vehicles and other machinery can not be compacted bentonite waterproof blanket. 4, the construction GM / GCL composite liner, the GCL has paved the completion date of the construction should be completed in the laying of 300mm HDPE film or thick clay layer of protection, the date can not complete the construction HDPE film or a protective layer of clay, bentonite response waterproof blanket were covered to prevent rain snow before leaving the GCL is hydrated and strong sunlight for prolonged sun exposure Waterproof blanket. So far, that the bentonite in the water, there are three forms: a water-free water, namely bentonite particles adsorbed water, heated to above 100 ℃, can remove free water Edison geotextile material waterproof blanket, freed from free water bentonite, bonding capacity is not affected; two water is strongly bound water, prolonged heating at 110 ℃, bentonite free water can be completely removed, but will not remove strongly bound water. Free water has been completely removed 3500g bentonite waterproof blanket, and then heating will continue to lose weight at a higher temperature (such as 200 ℃, 300 ℃), explained there is still moisture loss. Bentonite After this heat dehydration, just add water, to fully recover bonding capacity; three water lattice water, it was also known as structured water. Lattice water only at relatively high temperatures to remove part or all. Lattice water swelling water after removing waterproof blanket, namely the loss of bonding capacity, become a dead clay. Different bentonite, loss of bonding capacity of different temperatures. By differential thermal analysis results show: In general, natural sodium bentonite failure temperature of 638 ℃ waterproof blanket construction, calcium bentonite as 316 ℃. Artificial activation of sodium bentonite, as different activation conditions, failure temperature varies, but lower than the natural sodium bentonite. 5kg waterproof blanket | GCL | Edison New Material Co., Ltd. new material provided by Edison.
