The invention discloses an air source heat pump with a detachable defrosting device based on a super-hydrophobic fin heat exchanger and a working method thereof. The air source heat pump includes a gas-liquid separator, a compressor, a four-way commutator, a first heat exchanger, a second heat exchanger, a first fan, a liquid storage branch, a defrosting water circuit, and a defrosting refrigerant delivery branch. The defrosting water circuit includes a defrosting device, a first solenoid valve, and a second solenoid valve; the defrosting refrigerant delivery branch is installed between the refrigerant output end of the compressor and the first heat exchanger, and the defrosting cooling An electric regulating valve is installed on the agent delivery branch; the defrosting device is located below the first heat exchanger, and the frost layer condensed on the fin surface of the first heat exchanger can just fall off into the defrosting device; the defrosting device melts the frosting layer The heat comes from the heat released by the subcooling of the refrigerant output from the refrigerant delivery channel inside the second heat exchanger. In the defrosting process of the present invention, the frost layer on the surface of the fins falls off as a whole, which greatly reduces the defrosting time and effectively reduces the energy consumption of defrosting.

The invention discloses a steel pipe marking method and equipment. The method comprises the following steps: drying the steel pipe: drying the inner wall or the outer wall at the mouth of the steel pipe for use; painting the steel pipe: spraying the dried steel pipe on the mouth of the steel pipe Spray the paint on the inner or outer wall of the steel pipe for standby; steel pipe spray marking: when the painted steel pipe waits for a preset time and the paint is not dry, use ink to spray the inner or outer wall of the steel pipe nozzle. The ink includes the following Ratio of ingredients: cyclohexanone: 20‑30%, titanium dioxide: >10%. The equipment includes a mechanical arm, a transmission device and a marking assembly, and the transmission device is used to transmit steel pipes; the marking assembly includes a spraying head, a paint spraying head and a pneumatic water removal device, and the spraying head, a paint spraying head and a pneumatic water removal device Fixed on the mechanical arm, the pneumatic dewatering device is used to dewater the steel pipe. Adopting the above steel pipe marking method and equipment can increase the marking speed, and make the code sprayed on the steel pipe clearer and not easy to fall off.

The invention discloses a method for detecting the electrode plate joint shedding phenomenon of an electrothermal concrete pavement. The method comprises the steps of S1, measuring the current strength Ii of each power supply branch of the electrothermal concrete pavement, and judging whether each power supply branch is a suspected faulty line or not, wherein i is larger than or equal to 1; S2, powering on each suspected faulty line, and measuring the strengths of magnetic fields at each measuring point of a live line and each measuring point of a null line; S3, through the formula (img file = 'DDA 0001226839360000011. TIF 'wi = '177 'he = '118 ' / ), calculating the ratio of magnetic field strengths at each measuring point measuring point of the live line and each measuring point of the null line, wherein Ri represents the ratio of magnetic field strengths at the i measuring point, mli and mni respectively represent the magnetic field strengths at the i measuring points of the live line and the null line; S4, calculating the change rate of the magnetic field strength according to each magnetic field strength, and determining the shedding position of an electrode plate joint according to the change rate of the magnetic field strength. Based on the method provided in the invention, the specific shedding position of the electrode plate joint can be rapidly and accurately determined. Therefore, the lossless diagnosis for the electrode plate joint shedding phenomenon of the electrothermal concrete pavement can be realized.

The invention provides a low-carbon high-efficiency compound magnesium silicate energy-saving and heat-insulating material, comprising the following raw materials in percentage by weight: 21-27 percent of sepiolite, 10-13 percent of silicate pulping cotton, 6-8 percent of perlite, 5-7 percent of diatomite, 1-3 percent of sodium silicate, 1-2 percent of magnesia, 14-23 percent of aluminum silicatehigh-temperature cotton, 14-22 percent of brucite, 6-8 percent of high-temperature binding agent, 1-3 percent of stabilizing agent and 3-4 percent of penetrating agent.

The invention relates to a rotary garlic splitting device, which includes: a sorting input mechanism, which includes a sorting feeding component, a support platform, and a conveying component, and the center of the output end of the support platform is provided with a through slot along its length direction; the garlic transmission mechanism , which includes a transmission assembly and a first guide assembly; a kneading mechanism, which includes a support frame and two sets of kneading assemblies symmetrically arranged on the support frame, a kneading space is formed between the two sets of kneading assemblies, and the ejection assembly matches the transmission and kneading assembly ; Splitting mechanism, which includes a turnover assembly for driving the garlic on the transmission assembly to rotate and split the garlic and a garlic root shedding assembly that drives the garlic root on the transmission assembly to automatically fall off; the invention solves the problem of fixing the end of the fine needle as a barb type, and then complete the fixing of the garlic root, but the root is extremely inconvenient when dismantling, and it is easy to cause damage to the fixed needle simultaneously, reducing the technical problem of the fixed needle service life.

The invention discloses anti-sticking and weather-resisting paint, a sticking layer for sticking a water-stopping belt and concrete and a compound waterproof system. The paint is prepared from the following formula raw materials: heavy calcium carbonate, talcum powder, titanium dioxide and waterborne emulsion; and the waterborne emulsion contains a functional group which can be subjected to coordinated complexation with an alkaline group in the concrete. According to an anti-sticking and weather-resisting coating formed by the anti-sticking and weather-resisting paint, the functional group, which can be subjected to coordinated complexation with the alkaline group in the concrete, in the waterborne emulsion is subjected to the coordinated complexation with the concrete, so that chemical bond compounding is formed by the anti-sticking and weather-resisting coating and the concrete, and the adhesion force between the anti-sticking and weather-resisting coating and the concrete is enhanced. The anti-sticking coating is arranged on a pressure-sensitive adhesive layer and forms an adhering layer, and the adhering layer forms a wholly continuous and microscopic three-dimensional porous structure; and in a process of curing the post-poured concrete and the adhering layer, slurry formed by the post-poured concrete and the microscopic three-dimensional porous structure in the adhering layer form mechanical occlusion, so that the adhering layer and the concrete are tightly attached and adhered and do not easily fall off.
