Product Description: Construction Price per Square Meter for Black Asphalt Pavement Color ChangePerformance Characteristics of Colored Spray Coating:1. Aesthetic Color: The sprayed surface does not adhere to dust or particles. The entire binder system offers high strength and wear resistance, ensuring long-lasting color retention and aesthetics. It is oil-resistant, waterproof, UV-resistant, and suitable for long-term outdoor durability.2. Wide Application Range: Suitable for color restoration of colored asphalt pavements, as well as color change and beautification of cement, asphalt concrete roads, and various pedestrian pavements in any color.3. Simple Construction Process and Quick Traffic Opening: Compared to colored anti-skid paving, the construction process is simpler and more cost-effective. The seal coat offers brighter, more vibrant, and durable colors, with better adhesion, strength, weather resistance, and wear resistance compared to the original surface. Conventional spraying techniques can be applied directly to stable asphalt pavements, cement concrete, and pedestrian pavement surfaces. Each kilogram can cover 2–3 square meters, enabling rapid completion of large-area paving. A single spraying device can cover over 1,000 square meters per day, with fast curing in 1 hour. Traffic can be opened 2 hours after construction.4. Long Service Life: Its main component is a high-molecular inorganic composite material, which significantly outperforms common epoxy resin systems in terms of weather resistance, toughness, adhesion, and plasticity. One-time spraying can maintain color for 3–5 years without fading.5. Economical and Eco-Friendly: Low cost, environmentally friendly materials, and no pungent odor.6. Minimal Impact from Construction Environment: Can be applied quickly at room temperature using a spray painting machine, making construction simple and convenient. The surface appearance is improved, and the color is more durable. Even low temperatures do not hinder construction: it performs well in cold conditions and can be applied normally at temperatures as low as -30°C.III. Application Scope of Colored Spray Coating:Road color change, landscape roads, colored pavement restoration.Colored pavement spraying is a highly advanced road material widely used on various highways, pedestrian overpasses, non-motorized vehicle lanes, urban slow-traffic lanes, sidewalks, crosswalks, garden squares, factory and warehouse areas, school campuses, residential areas, parking lots, underground garages, stairways, and more.IV. Construction Steps for Colored Spraying Machine: Pre-Construction Base Treatment1. New black asphalt surfaces require fine-grained asphalt leveling, compaction, and cooling.2. Old asphalt pavements need repair, cleaning, and primer treatment before spraying.3. Before construction, ensure the availability of water and electricity, traffic access, mixing and storage areas, temporary sheds, warehouses, and fire safety facilities.4. Pay attention to environmental protection during construction.Pavement Construction1. Mix materials thoroughly according to the required ratio.2. Apply masking tape as per road design requirements to prevent contamination.3. Mix modified polymer emulsion with colored powder in proportion using a high-speed mixer for 3 minutes, let stand for 3 minutes, then mix for another 2 minutes before use.4. Pour the mixed material into the spraying container. Stir while spraying.5. After the polymer coating dries (2–4 hours), spray the colored surface layer.6. After construction, allow 1–2 days for curing and cleaning before opening to traffic.V. Key Considerations for Colored Pavement Spray Coating Construction:1. Newly paved asphalt surfaces have not undergone the elastic kneading action of vehicle tires, so the asphalt in the mixture may not fully bleed, leaving larger voids. During spraying, the color-changing agent may penetrate these voids and react slightly with free asphalt.2. For newly paved asphalt surfaces, color change construction should be performed at least 1 week after opening to traffic. If the schedule is tight, within 2 days after paving and under clear weather conditions, use a tire roller to repeatedly compact and knead the new pavement to improve asphalt bleeding before color change construction. If yellowing occurs during spraying, increase the distance between the spray nozzle and the pavement or adjust the sprayer pressure to 6 MPa. Spray at a 45-degree angle to the pavement (this method reduces the penetration of the color-changing agent into asphalt particles, preventing complete encapsulation of aggregate particles and loss of the oil film). For non-new pavements, the pressure should be 8 MPa, still at a 45-degree angle.3. For white primer spraying on asphalt pavement, maintain a distance of 40–1250 px between the spray nozzle and the ground. Apply two coats with an interval of at least 40 minutes between coats.4. Colored topcoat spraying should be performed after the primer has fully cured. Generally, apply two coats with an interval of at least 40 minutes between coats. more>

Product Description: Construction of Pig Farming GreenhousesIn many rural areas, greenhouse pig farming is practiced to effectively reduce costs and improve breeding efficiency. The first step in greenhouse pig farming is building the pigpen, 1. Site SelectionGreenhouses lack the sturdiness of walls, so they should be located in leeward areas or windbreaks. Additionally, the greenhouse should be built on relatively high ground with low groundwater levels, dry conditions, good transportation access, ample water sources, and no pollution. The overall construction area should be flat, without slopes.2. Pigpen DesignFirst, the size of the greenhouse should be determined based on the scale of farming. Typically, it is about 12 meters wide and 80 meters long, with the pigpen oriented east-west to maximize sunlight. Roll-up curtains should be installed around the pigpen for effective ventilation. The floor can be made of concrete, and the pigpen should have separate pigsties, each partitioned with bricks or iron railings. Each pigsty should have a sloped manure and urine gutter. 3. Greenhouse ConstructionFor the materials of the pigpen greenhouse, steel pipes can be used, and the roof can be arched. Openings should be left on both sides of the greenhouse to facilitate ventilation. Inside the greenhouse, feeding troughs and water troughs should be installed. Additionally, a space of 1 to 1.5 meters should be reserved for storing feed materials. The feed shed and the pigpen should be separated by feeding troughs, with a movable door connecting them.4. Roof CoveringAfter the main structure of the greenhouse is built, it should be covered with film. Double-layer ethylene drip-free film or single-layer film can be used, or colored film can be substituted depending on specific needs. Additionally, 2-3 ventilation holes should be created at the top of the greenhouse film, and operable openings should be installed to expel harmful gases generated inside the pigpen. more>

Product Description: Building a sheep shed has its own advantages, making it more suitable for raising sheep in the cold winter regions of the north. It is cheaper than brick structures, warmer in winter, and has low construction costs—these are the benefits of a sheep shed. So, how do you build a sheep shed?First, prepare the necessary materials. These include plastic, nails, steel, breeding film, etc. Once these materials are ready, you can proceed to the next step.Next, find a suitable location and dig four holes. These holes mainly serve to support the entire shed, and then place steel pipes into them. After that, start using the steel pipes to build the roof. Once the roof is set up, secure it with nails and film ropes to prevent it from being blown down by strong winds or heavy rain.Then, build fences around the steel pipes. After all, sheep are quite strong, so adding fences around the steel frame will further reinforce the shed.Finally, cover the shed with plastic. The plastic should also be secured with nails to prevent it from being blown away by the wind and to ensure it stays in place. more>

Product Description: For raising rabbits, a greenhouse is more suitable as it can provide shade, shelter from rain, ventilation, and warmth.In areas with vast grasslands, wild rabbits tend to choose sparse vegetation areas to build their nests, such as on the prairie. In areas without grass, they will try to find places with grass to nest, even if it's just a clump of grass—they will nest right under that clump. A typical example is in deserts, where wild rabbits are more easily found in places with grass.During hot summers, wild rabbits choose to hide in shaded ditches or embankments, often not sticking to a fixed hiding spot; they may change locations after a night or two.In colder winters, wild rabbits opt for sunny, grassy ridges or embankments to hide. As long as the withered grass in their hiding place remains intact, they will use it for a relatively long time. In the even colder northern regions with sandy soil, wild rabbits dig burrows in dry and concealed spots to hide, staying there for at least the entire winter.During spring, summer, and autumn, when the climate is warmer, the fields are filled with green grass and tender crops. Wild rabbits have no shortage of food, nest and give birth more casually, and generally move around frequently. more>

Product Description: Nowadays, more and more people are starting to raise livestock to make money, and sheep farming is a relatively popular choice. Mutton is tender and flavorful, highly nutritious, and can even help keep warm when eaten in winter, which is why many people enjoy it. Nowadays, many sheep farmers prefer to build greenhouses for raising sheep, and selecting the site for the pen is crucial.The site for constructing the greenhouse should be chosen in a high and dry area to prevent water backflow and ensure smooth drainage. At the same time, factors such as disease prevention, convenient transportation, sufficient water sources, good water quality, and avoiding windy locations should also be considered. Determining the orientationTo make full use of solar energy, the pen should be built facing south, with a north-south orientation. The deviation to the east or west should not exceed 15°. If the sheep pen must be oriented north-south due to site constraints, the roof can be a fully arched plastic shed, with a central corridor and double rows on both sides. There should be no tall buildings in front of the sheep pen within a certain distance to avoid obstructing sunlight, which is more suitable. The slope of the plastic film in the greenhouse refers to the angle between the plastic film and the ground plane. It should be controlled between 40° and 55° to achieve a higher light transmission rate. more>

Company: Hebei Baofei New Materials Co., Ltd.

Product Description: Performance Aspects · Dimensional and Shape Stability: Pellets can maintain their original size and shape under high temperatures without significant expansion, contraction, deformation, or fragmentation due to thermal stress and other factors. For example, in the blast furnace ironmaking process, if pellets have poor thermal stability, they may break into small pieces or powder in the high-temperature zones of the furnace, affecting the permeability of the furnace burden column and the smooth operation of the furnace. · Strength Stability: Pellets can maintain a certain mechanical strength in high-temperature environments without experiencing a sharp decline in strength. Sufficient strength is necessary to withstand the pressure from the upper burden in the blast furnace and the forces from rising gas, preventing pellets from breaking due to collision and compression during transportation, charging, and smelting. · Chemical Stability: The chemical composition of pellets remains stable under high temperatures, without excessive oxidation, reduction, decomposition, or other chemical reactions, to avoid affecting pellet performance and subsequent ironmaking processes. For instance, iron oxides in certain pellets should undergo reduction according to the expected reaction pathway at high temperatures, rather than abnormal reactions that alter pellet properties. Importance · Ensuring Blast Furnace Permeability: Pellets with good thermal stability can remain intact in the blast furnace, maintaining reasonable gaps between the burden materials, allowing gas to pass through the burden column evenly and smoothly. This facilitates good gas-solid mass and heat transfer processes, improving blast furnace production efficiency and gas utilization. · Maintaining Blast Furnace Operational Stability: Stable pellets enable more uniform burden flow and temperature distribution within the blast furnace, reducing fluctuations in furnace conditions caused by pellet breakage and pulverization. This lowers the probability of abnormal situations such as furnace wall erosion and channeling, ensuring stable blast furnace operation and extending its service life. · Improving Ironmaking Quality and Output: Good thermal stability of pellets ensures that reduction and other reactions proceed according to the predetermined mechanisms in the blast furnace, making the iron reduction process smoother and more efficient. This helps improve the quality and output of molten iron while reducing energy consumption and production costs. Influencing Factors · Raw Material Characteristics: The type, particle size distribution, and chemical composition of the ore powder can affect the thermal stability of pellets. For example, impurities and moisture content in the ore powder, if too high, may have adverse effects during heating. · Binder Usage: The type, dosage, and performance of binders are crucial for pellet thermal stability. Suitable binders can form strong bonds between pellet particles, enhancing thermal stability; conversely, improper binder selection or insufficient dosage can lead to issues such as pellet breakage under high temperatures. · Production Processes: These include pelletizing, drying, and roasting processes. For instance, improper control of roasting temperature and time may result in insufficient or excessive roasting, affecting the crystal structure and strength of pellets, thereby reducing thermal stability. more>
