The application relates to the technical field of concrete, and specifically discloses a permeable concrete and a construction method thereof. The raw materials of the permeable concrete include, in parts by weight: 100-140 parts of water, 1300-1700 parts of gravel, 400-550 parts of cement and 150-300 parts of polyurea. The construction method includes the following steps: S1: stirring and mixing; S2: paving and vibrating; S3: demoulding; S4: curing; S5: coating sealant; S6: rolling coating; Polyurea; After S6 treatment, permeable concrete is obtained. Since the application uses polyurea in the pervious concrete, the compressive strength of the final pervious concrete is enhanced.

The invention discloses a high-low temperature environment air-cooled chiller unit and a control method thereof. By adopting the cooperation of a water system and a cooling system, the overall unit is reasonable in design, intelligent in control, wide in adaptation environment range and stable and reliable in operation, energy is saved, and important significance on improving the reliability, operated for a long term and under the limiting ambient temperature, of the air-cooled chiller unit used in a data center or a process requirement place where cooling is still needed under the high temperature environment and low temperature environment is achieved.

The invention relates to the technical field of metal material anticorrosion, and specifically discloses a basic iron oxide anticorrosion coating and a preparation method thereof. The anticorrosion coating comprises the following components (by weight): 1%-8% of lithium, 50%-69% of iron, and 30%-35% of oxygen. The coating is a single-layer or multi-layer composite structure, which can be used for high and low temperature corrosion protection of iron, iron-based alloys, and steel metal materials in water, atmosphere, soil, industrial media, and molten salt electrolytes, and has a wide range of environments and temperatures. range, especially resistant to Cl ‑ and F ‑ erosion, showing excellent anti-aging ability.

The invention relates to a multi-medium heat storage type warming water tank, which is a warming water tank for storing heat by using media such as electromagnetic oven heated water and the like, infusing hot water by using a manual or electric water feeding device and achieving heat storage and warming by using electricity, fuel combustion, hot water of a solar water heater and geothermal water. The warming water tank comprises a warming panel, a warming cavity, a plastic or metal plate, a cotton cloth layer and a water cavity, wherein the water cavity is provided with a water inlet pipe, a water outlet pipe, a stainless iron warming plate and a special bearing rack; a heat insulation layer and a plastic (or metal) protective shell are arranged outside the water cavity; the warming water tank for hands and feet of a single person is provided with a detachable heat insulation base; a water passage of the warming water tank for feet of multiple persons is provided with a three-way pipe and a heat resistant pipe connected with a water pipe of the water cavity; and the warming water tank mainly applied to warming of households and individuals and warming of feet of multiple persons also can supply hot water and shower, the heating transfusion device type warming water tank can be used for warming, and the manual or electric water feeding device is used for feeding water to the water tank. The warming water tank has the advantages of convenient operation, safety, environmental protection, energy conservation, sanitation, warming comfortableness, duration, high utilization of heat efficiency, wide available energy and durability.

The invention discloses a superhydrophobic sponge, its preparation method and application. The method is to put the prepared polydivinylbenzene into absolute ethanol, stir ultrasonically to prepare a polydivinylbenzene suspension, soak the cleaned and dried sponge for 3 min, and then put it in an oven to dry to obtain Superhydrophobic sponge. Compared with other processes, the preparation process of the present invention is simple and feasible, the environment is mild, and there is no requirement for complicated equipment and instruments. The contact angle can reach 154.4°, showing superhydrophobic and superlipophilic properties, which can effectively separate oil-water mixtures and also have good adsorption for volatile organic compounds. The superhydrophobic sponge prepared by the invention can be widely used in the fields of water pollution control, air pollution control and the like.
