Q:What's the technical standards of geomembrane?
The national standards of geomembrane is GB / T17642-2008. Geomembrane 1. longitudinal and transverse breaking strength. 2. Vertical and horizontal elongation corresponding to the standard strength. 3. CBR bursting strength 4. 5 vertical and horizontal tearing strength. 5, hydrostatic pressure resistance. 6. peel strength. 7. vertical penetration index. 8, width deviation, the above technical requirements that confirm to the national standard are national standard geomembrane.
Q:What are the specifications of the reinforced glass fiber?
The glass fiber reinforced earth grid is a new type of excellent soil base material to enhance the road surface and roadbed. The product is made of high quality enhanced alkali free glass fiber yarn, and the introduction of foreign advanced warp knitting machine made. It is with very high tensile strength, low elongation, high elastic modulus, resistance to high and low temperature performance of excellent properties, through excellent modified asphalt coating, with excellent alkali resistance and aging resistance, widely used in the asphalt pavement, cement concrete pavement and roadbed enhancement, whether hard pavement and flexible pavement is universal, and traditional pavement ratio can reduce the cost, prolong the life span and preventing the road reflective crack, the product can also be used for the enhancement of railways, airports, water conservancy, dams and other soft soil and enhance the pavement. Performance specifications: EGA1 * 1 EGA1 * 1 EGA1 * 1 EGA1 * 1 EGA1 * 1 EGA1 * 1 EGA1 * 1 EGA1 * 1 EGA2 * 2 EGA2 * 2 radial fracture strength (KN\m) = 30 = 50 = 50 = 80 = 100 = 120 = 140 = 160 = 60 = 80 = zonal 30 = 50 = 60 = 80 = 100 = 120 = 140 = 160 = 60 = 80 = 4% = 4% elongation% = 4% = 4% = 4% = 4% = 4% = 4% = 4% = 4% mm 25.4 x 25.4 mesh size 25.4 x 25.4 x 25.4 25.4 25.4 x 25.4 x 25.4 x 25.4 25.4 25.4 25.4 25.4 x 25.4 x 25.4 x 12.7 x 12.7 12.7 12.7 7676767676767676 7676 width elastic modulus (m) 1-6 1-6 1-6 1-6 1-6 1-6 1-6 1-6 1-6 1-6 temperature (DEG C) -100-280 -100-280 -100-280 -100-280 -100-280 -100-280 -100-280 -100-280 -100-280 -100-280 guttacontent% = 20% = 20% = 20% = 20% = 20% = 20% = 20% = 20% = 20% = 20% at the surface High quality modified asphalt
Q:How to lap geomembrane?
filament geotextile, the lap joint of film should be more than 10cm, the destroyed place should be repaired with welding gun. it's materials include HDPE geomembrane, short fiber geotextile is thick or thin, the lap joint of geomembrane is welded with special welder.
Q:How to use electrothermal film?
Clip must be used on one of the ends of the wire and then connect the wire, wrap with daub and black rubber in case of electric leakage, and on another end of the wire should be wrapped with professional daub and black rubber in case of electric leakage. It is about 200 watts per square meter.
Q:What is the welding method of geotextile?
It is easy to weld the geotextiles that manual rolling and paving is enough. The surface should be flat with some deformation allowance left. The long or short nonwoven geotextiles are often bonded by lapping, seaming and welding. The seamed and welded overlap is generally more than 0.1m wide. The lapped overlap is generally more than 0.2m wide. For geotextiles with long exposure time, methods of welding and seaming are recommended. Continue seaming until the all the work is completed. (disconnected seaming is not allowed.) Before being bonded, the overlaps should not be less than 150mm wide. The minimum distance of seams to the edges (the exposed edge of material) is 25mm. The thread for seaming should be made from resin with tensile strength no less than 60N, with chemical resistance and UV resistance that are the same with that of geotextile or exceed that of geotextile. Any "missed stitch" should be avoid. Actions should be taken accordingly to prevent emission of soil, particulate matters or foreign matters.
Q:What is 3m film?
It is very good for use. The 3M Innovative technology can provide a superior screen protection against scratching and damage and give the lasting protection. It allows your digital reproduction equipment a more aesthetically pleasing look and clearer images. 3M special optical glue to make your screen protector easy attachment and removal without leaving any traces when cleaning. The 3M Scotchgard ™ technology can easily erase the fingerprints and the greasy dirt.
Q:Does thermal insulation glass need to stick membrane ?
1, That depends on your requirement for ultraviolet-proof amount. If the coated glass has met you demand, you don't have to stick membrane. of 2, If not, sticking a layer of membrane is ok. If you choose deep color glass, it would be better not to stick membrane again.
Q:Does rock wool look like glass wool ?
No, there are two kinds of products. Main raw material of rock wool is basalt while that of glass wool is glass.
Q:Painting film thickness standard
there is no specific criteria. no matter what kind of painting you are sparying, you can not brush until the treament of coating surface, otherwise there is no way to guarantee quality. brushing by hand for 2 - 3 times. Simple brushing needs at least two sides, if advanced brush need to be able to see the film thickness, it would need the N side. brushing until you are satisfied, pay attention to the quality of spraying, and pay attention to environmental protection
Q:These two kinds of glass wool are used as insulation materials, but one keeps 0.3 in specific gravity while the other keeps 0.5 in specific gravity. Which one should be chosen?
It mainly depends on what would you use it for and what temperature of thermal insulation do you need. You can directly look through thermal insulation property of glass wool for further information. If you needs better thermal insulation effect, you can choose heavier specific gravity. If you are not so demanding, you can choose lighter ones.
