1. When the load is 720kPa and therefore the gradient is 2%, the permeability is 2500m/d and therefore the flow is 13 pm/m.
2. The creep test retained quite 60% thickness after bearing 1200kPa load for 10000 hours.
3. three-rib China storage and drainage sheet factory mesh core lampblack content isn't but 2%, density 0.94g/cm3, lastingness isn't but 36.5kn /m, melting index 1.0g /10min, thickness 7.6mm.
4. Non-woven geotextiles have a clear aperture of 0.18mm, a permeability of 0.26 sec-1, a permeability of 0.2cm/ Sec, a puncture strength of 580N, a trapezoidal tear strength of 356 N, a holding lastingness of 900 N, a holding lastingness of fifty, and a bursting strength of 2750kPa.
With the event of recent industry, the need for environmental cleanliness is higher and better, therefore the need for a composite drainage network is more urgent. the most requirements for the composite drainage network drainage efficiency are small, used as composite drainage network material is usually impermeable membrane, also useful non-woven geotextiles.
The dimple drainage board price is arranged within the fiber orientation, the yarn itself is just too tight, and therefore the warp and weft cross structure, there's an outsized gap between the yarn, the yarn itself Closely, attempt to warp/weft crossover structure, features a large gap between yarn, so as to enhance the filtering effect, general requirements fabric approximate, but it's a filter resistance increases, on the paper, due to the tightly, gap small and fewer, filter material stockpile increased slightly increased quickly filter resistance, the filtering efficiency drops, at an equivalent time its wrinkle resistance is poor, seriously affect its service life.
A composite dimple drainage board factory price network thanks to fiber mixed and disorderly arrangement, and there's no warp/weft intersection, method of melt-blown nonwovens has more fiber thin, fleeciness structure, the gap between fiber and therefore the pore size is little, good wrinkle resistance advantages, composite drainage network can receive high filter efficiency, filter resistance, long service lifetime of composite drainage net effect, at an equivalent time, due to the massive fiber intake capacity between even make the merchandise to stay a particular amount after filtering material can still maintain a coffee filter resistance, if choose polypropylene fiber, due to the fine denier fiber, a specific area is big, good resistance to chemical corrosion, composite drainage net dragon it adapted to the economic filtration material, thanks to the superb characteristics of composite drainage net, In some ways, woven press cloth and paper are replaced by composite drainage nets.
