Description

Technical Field

[0001] The utility model relates to the technical field of adhesive storage, in particular to a storage workshop for PU adhesives. Background Art

[0002] PU adhesive is a polyurethane adhesive, which is an adhesive containing urethane group (-NHCOO-) or isocyanate group (-NCO) in its molecular chain. This adhesive is obtained by reacting isocyanate with hydroxyl-containing compounds such as polyester, polyether, castor oil or other polyols, and has excellent properties, such as strong molecular designability, wide range of physical properties, wide range of bonding applications, etc. It is one of the important varieties of synthetic adhesives. PU adhesive can not only cure at room temperature, but also can be cured by heating, and has excellent adhesive properties to a variety of materials such as metal, rubber, glass, ceramic, plastic, wood, fabric, leather, etc. In addition, PU adhesive also has the ability to withstand impact vibration and bending fatigue, especially its extremely excellent low-temperature resistance, which is second to none among existing glues. The application range of PU adhesive is extensive, including but not limited to coating on dry laminators, adjustment of coating amount, drying process, control of bonding temperature, adjustment of compound pressure, and curing process, etc., which are all key steps to ensure its efficient bonding.

[0003] However, the storage of PU adhesive is extremely likely to affect the quality and performance of PU adhesive. PU adhesive is a material with strong moisture absorption. A humid environment and the intrusion of water vapor will affect the use effect of PU adhesive; PU adhesive is prone to aging, embrittlement, etc. under sunlight; the entry of air and impurities will affect the performance and service life of PU adhesive; PU adhesive is not resistant to high temperature and is extremely likely to cause a fire when in contact with a fire source.

The display 224 is provided above the left of the air outlet 222. The display 224 displays the humidity inside the workshop 1 in real time. The humid air is drawn into the dehumidifier 22 through the air suction port 223. Through the heat exchanger, the water molecules in the air are condensed into water droplets at this time. The processed dry air is discharged outside the machine through the air outlet 222. Such a cycle keeps the workshop 1 dry. See the specific details below. Figure 1 , Figure 2 , Figure 3 .

[0025] The fire protection system 3 includes a bracket 31, a fire extinguishing agent bottle 32, an air delivery pipe 33, and a smoke sensor 34. The bracket 31 is placed on the bottom surface of the factory building 1. The bracket 31 includes a combined rack 311 and a support rack 312. The fire extinguishing agent bottles 32 are arrayed in the combined rack 311. The interior of the fire extinguishing agent bottles 32 is filled with carbon dioxide gas. The support rack 312 is supported and fixed at one end of the air delivery pipe 33. The air delivery pipe 33 is connected to the top end of the fire extinguishing agent bottle 32. The air delivery pipe 33 is distributed on the inner top surface of the factory building 1 and is used for the transmission of carbon dioxide gas. There are three smoke sensors 34, all of which are arrayed on the inner top surface of the factory building 1. The smoke sensors 34 are connected to the power supply system 4 via a circuit. Through the real-time monitoring of the smoke inside the factory building 1 by the smoke sensors 34, after detecting the smoke, an instruction can be transmitted to the fire extinguishing agent bottle 32 in the first time, and the valve is automatically opened to discharge the carbon dioxide gas, so as to achieve the effect of extinguishing the fire. The fire extinguishing agent bottle 32 includes a bottle body 321 and a pilot valve 322. There is carbon dioxide gas in the bottle body 321. The carbon dioxide gas is input into the air delivery pipe 33 through the pilot valve 322. The pilot valve 322 is connected to the power supply system 4 and the smoke sensor 34 via a circuit. The air delivery pipe 33 includes a high-pressure hose 331, a manifold 332, a check valve 333, a shunt pipe 334, and a jet nozzle 335. The high-pressure hose 331 is sleeved on the pilot valve 322. The high-pressure hose 331 is threadedly connected to the manifold 332. The manifold 332 collects the carbon dioxide gas in the bodies of multiple fire extinguishing agent bottles 32. A check valve 333 is sleeved at the distal end of the manifold 332. The top end of the check valve 333 is threadedly connected to the shunt pipe 334. The shunt pipe 334 branches on the inner top surface of the factory building 1. The carbon dioxide in the manifold 332 is diffused and discharged into the factory building 1 through the shunt pipe 334, increasing the fire extinguishing range and ensuring the safety inside the factory building 1. The shunt pipe 334 has several air outlet ends. The jet nozzle 335 is threadedly connected to the air outlet end of the shunt pipe 334. The carbon dioxide gas is ejected through the jet nozzle 335. By using the carbon dioxide gas with high density and 100% purity in the fire extinguishing agent bottle 32, it can quickly sink to the bottom of the fire source and squeeze out oxygen, forming a dense protective layer and a stacking layer, effectively reducing the oxygen content in the space, preventing the PU adhesive in the storage area from contacting the fire source, and avoiding the occurrence of fire. The power supply system 4 includes a solar panel 41 and a solar bracket 4231. The solar panels 41 are arrayed on the top surface of the factory building 1 to absorb sunlight and prevent the sunlight from directly shining on the factory building 1. The solar bracket 4231 supports the bottom of the solar panel 41. The solar panel 41 converts solar radiant energy directly or indirectly into electrical energy through the photovoltaic effect or the photochemical effect by absorbing sunlight. The solar panel 41 supplies power to the dehumidifier 22, the group of fire extinguishing agent bottles 32, and the smoke sensors 34 via a circuit. For details, see Figure 4 。
