The company has introduced an advanced technology from the United States, integrating its extensive experience in product design and strong R&D capabilities in the field of road maintenance machinery. This innovation led to the creation of a new masterpiece: the sand-fogging seal spreader.
The sand-containing seal layer is made up of a blend of mist seal material and sand, primarily composed of modified emulsified asphalt or coal pitch-based materials, along with clay and polymer additives. A specialized high-pressure spray vehicle is used to apply this mixture as a thin layer onto asphalt pavements. This process effectively seals micro-cracks, prevents loose stones from falling off, blocks water infiltration, delays asphalt aging, reduces surface temperature, and maintains the road’s skid resistance, significantly enhancing the overall appearance of the road.
**Technical Characteristics**
1. This innovative pre-conservation technique is ideal for roads in their early stages of use. It helps delay the onset and progression of pavement distresses, maintaining a good service condition at a low maintenance cost. It is especially suitable for roads that have been open for 2 to 3 years and show no severe issues.
2. The technology can also be applied to pavements with severe asphalt aging. Its self-reduction and regeneration properties help improve aged asphalt, leading to a noticeable enhancement in the pavement's appearance.
3. The system offers effective waterproofing and improves the road’s skid resistance. By mixing sand of the right particle size with a reducing agent and applying it under high pressure, it combines the benefits of both a sealing layer and a fog seal, addressing the common issue of poor skid resistance in traditional fog seals and ensuring safer driving conditions.
**Ordinary Benefits**
1. It has good permeability, preventing loose pieces or fine sand loss.
2. It is waterproof and resistant to petroleum compounds, de-icing agents, and more.
3. It is less prone to cracking or peeling, with high viscosity, flexibility, and durability. It can restore asphalt performance and extend its lifespan.
4. It helps reduce annual maintenance costs.
5. It enhances the road’s appearance and improves the visibility of markings on runways, highways, and parking lots.
6. The construction process is simple and fast, allowing for quick reopening of traffic.
**Special Advantages**
1. Utilizes advanced sand spraying technology to ensure road friction remains within a safe range.
2. The sealing material “breathes,†offering both waterproofing and ventilation.
3. It is environmentally friendly, water-based, non-toxic, and emits no irritating gases.
4. It features a unique snow-melting function, lowering the melting point by 5 degrees and reducing chemical corrosion on the road surface.
Cordierite Ceramic
The main raw materials of cordierite ceramics are talc, clay, alumina, feldspar and the like. Made using a general ceramic process. The sintering range is narrow, and the sintering temperature differs only a few degrees from the decomposition temperature of cordierite, making it difficult to obtain a dense body. As an additive, chlorite, magnesium carbonate, cesium carbonate, zirconium silicate, zirconium dioxide, boron trioxide, spodumene, etc. are generally used as additives to lower the sintering temperature, expand the firing temperature range, and improve the dielectric. performance. It can be used as a coil former, an arc-resistant electrical insulating material, a base material of a composite material, a material of a burner nozzle of an electric heating insulating device, and the like.
