Basalt geogrid-玄武岩土工格栅

Basalt continuous fiber material uses basalt ore as raw material. After crushing the ore, it is added to the furnace. After melting at 1450 ℃ to 1500 ℃, the uniform molten material is first drawn into coarse fibers through wire drawing leakage plates. Then, the coarse fibers are drawn into various specifications of continuous fibers by wire drawing machines, and different agents are used for treatment according to subsequent uses. Compared with other high-performance fibers such as glass fiber, carbon fiber, aramid fiber, etc, Basalt fiber not only has excellent mechanical properties, but also has many excellent functional properties, such as good high-temperature resistance, continuous operation within the range of -260~700 ℃, acid and alkali resistance, strong UV resistance, low moisture absorption, and better resistance; Good insulation performance, high temperature filtration, radiation resistance, etc. Therefore, basalt fiber is a low-cost substitute for carbon fiber and the fourth largest high-tech fiber after carbon fiber, aramid fiber, and ultra-high molecular weight polymer fiber.

Production process: Panjin epoxy resin sealant is a dark blue production adhesive, strictly following *. The S in asphalt should be changed according to the three aspects of swelling, cutting, and design. The swelling rate of S accelerates with the increase of temperature, and its relative density of swelling components ranges from 0.97 to 1.01g/cm3, which is close to the relative density of aromatic components.

One is soil erosion. Tourists and horses are willing to walk on grass, and the small paths they tread on are eroded and eroded by rainwater, forming erosion gullies. The soil in the gullies is poor, often without any grass or rocks. The second is the grazing of cattle and sheep. The surrounding villagers graze freely, leaving behind cow manure and sheep manure with high fertility, which can harm the grassland. Thirdly, tourists ride horses.

(1) Due to the presence of joints and cracks, the overall strength of the old cement concrete pavement as the base layer is maintained, and under external forces, the asphalt overlay is in a three-dimensional stress state. When vehicles pass through discontinuous slabs, due to the vertical reflection crack displacement difference between adjacent plates on both sides of the joints and cracks, the asphalt overlay layer experiences significant shear stress at the corresponding position. This shear stress is the main reason for the reflection cracks in the asphalt overlay layer.

Basalt fibers are resistant to acid, alkali, and water corrosion. The components such as K2O, MgO, and TiO2 contained in basalt fibers play an important role in the chemical corrosion resistance and waterproof performance of the fibers. Basalt fibers have good durability in saturated Ca (OH) 2 solutions and alkaline media such as cement, and can maintain a high degree of durability.

The ground gap grouting adhesive should use asphalt concrete as the raw material, and modify the asphalt concrete according to the production process of *. Ground gap grouting adhesive has low cost, good moisture resistance, and no fluidity in summer. Different solid models can be selected for different temperature zones. Introduction to Panjin Epoxy Resin Joint Sealant - Ground Filling and Sewing Adhesive: Panjin Epoxy Resin Joint Sealant Ground Filling and Sewing Adhesive, also known as Road Sealing Adhesive, is a raw material for ground filling and sewing.

Basalt geogrid is a flat network material made of basalt fiber yarn that is alkali resistant, acid resistant, and corrosion resistant, woven into a substrate using advanced warp knitting machines from abroad. It adopts a warp knitting oriented structure, fully utilizing the yarn in the fabric to have good tensile strength, strength, and creep resistance. It is also coated with high-quality modified asphalt to form a network. The basalt geogrid has the advantages of basalt fiber, such as high temperature resistance, freeze-thaw resistance (-260-650 ℃), consistent with the thermal coefficient of asphalt concrete, high tensile strength, UV protection, good chemical resistance, aging resistance, etc., which can be used for road reinforcement, resistance to cracks and ruts and other road diseases, ending the problem of difficult reinforcement of asphalt pavement.

Vegetation blankets are suitable for highways and railways: to protect the slopes on both sides of embankments and road surfaces, and to prevent soil erosion. 2. River and water bank: Protect the river and water bank from soil erosion caused by erosion. 3. Mountain: Protection of soil and water, vegetation survival rate, and greening rate. 4. Use soil and water conservation blankets as reinforcement for road engineering drainage channels.

The amount of road sealing adhesive used to fill the gap is divided into two stages, with each stage filling 4/5 of the groove depth. The second stage of road sealing adhesive is used to fill the gap and a 60mm wide and 3mm thick sealing layer is formed on both sides of the groove. (6) Spreading and curing. Spread stone powder or fine sand on the surface of the newly filled sealant, and allow the sealant to cool to room temperature before opening to traffic. The general cooling time is 15 minutes.
