Plastic blind ditch

Plastic blind ditch material is called Geocomposite dreinage systems (GDS), also known as three-dimensional drainage board, and drainage drainage dark channel material for civil engineering. The three-dimensional porous material is obtained by heating and melting a thermoplastic synthetic resin, extruding the fiber filaments through a nozzle, and sintering the joints.

The composition of the plastic blind ditch is about 2mm, and the joints are sintered and formed into a three-dimensional mesh body. The principle is the same as the truss principle of the steel structure. The surface opening is 95-97%, which is more than 5 times that of the perforated tube, 3-4 times that of the resin mesh tube, and the surface water absorption rate is extremely high.



Because it is a three-dimensional structure, its void ratio is 80-95%, the space is the same as that of management, and the pressure resistance is 10 times stronger than that of the tube structure. Therefore, even if it is pressed due to overload, it is a three-dimensional structure. Therefore, the residual space is also more than 50%, there is no problem of water leakage, and it is not necessary to consider being crushed by the earth pressure. The compressive strength is large, and the compression ratio is less than 10% under a pressure of 250 KPa. With anti-aging agent, it is durable and can be stable under water and in the middle of the earth for several decades.

The plastic blind ditch is a three-dimensional porous material obtained by heating and melting a thermoplastic synthetic resin, extruding the filaments through a nozzle, and dissolving the joints. The geotextile is wrapped around the main body as a filter membrane, which has a porous rectangular shape, a hollow rectangular shape, a porous circular shape, and a hollow circular shape, and has various sizes and specifications. It has been used abroad for more than 20 years and is widely used in tunnel anti-seepage drainage, roadbed drainage of railway roads, soft foundation embankment, retaining wall anti-filtration, slope and slope drainage, drainage and moisture protection of underground buildings, and drainage of lawns. The system, the drainage of the Tiantai Garden, the sewage treatment plant and the landfill, and other projects have been widely welcomed by the engineering community.

In the past 20 years, a large number of engineering examples at home and abroad have fully demonstrated the reliability of this product. The product has been tested by the Ministry of Communications, the Ministry of Water Resources and the Nanjing Institute of Water Resources of the Ministry of Power Industry. The product quality and performance indicators have reached national standards. Some indicators have surpassed Japan, and prices are far lower than those imported from Japan.

Hengshui Yifeng Technology Co., Ltd. specializes in producing water-proof and waterproof materials for various water conservancy projects. There are many types of products, complete models and quality assurance. Users in need are kindly requested to call to discuss business. Sales hotline

Polyacrylamide (PAM)is a kind of water soluble polymer, has unique effect to increase the viscosity of water or to promote the flocculation of particles present in water, it can also reduce the frictional resistance between the liquid.

According to the different ion characteristics, PAM has three types: Anionic PAM, Cationic PAM and Nonionic PAM.

Application

(1) As a flocculating agent, mainly used in industrial solid-liquid separation process, including settlement, to clarify, concentrate and sludge dewatering processes. Applications for all the major sectors are: Urban Sewage Treatment, Paper, Food Processing, Petrochemical, Metallurgical Processing, Dyeing and the Sugar and all kinds of industrial wastewater treatment.

(2) In the paper industry can be used as dry strength agents, retention agent, filter aid. They can be greatly improved as paper quality, enhance the physical strength of paper and reduce the loss of fiber, can also be used in the treatment of white water at the same time, in the deinking process can play a significant flocculation.

(3)In the mining, coal mining industry can be used for waste water, coal washing waste water clarifier.

(4)They Can be used for dyeing wastewater, leather wastewater, oily wastewater treatment, so that turbidity removal, decolorization, to achieve the emission standards.

(5)For the tap water in the river water treatment plant flocculant
