Problems solved by technology

Due to the high viscosity of the fire retardant coating, the construction temperature of the material needs to be kept at 50 to 60°C, so the performance requirements for the construction equipment are relatively high, and the spraying method is also relatively complicated
At present, the problems of this kind of paint spraying equipment are as follows: 1. The heating cycle of the equipment paint is completed by the proportioning plunger pump, which aggravates the wear of the proportioning plunger pump, thereby changing the cylinder volume of the proportioning plunger pump, and the paint is easy to seep Leakage increases the error of the proportioning accuracy, shortens the service life of the equipment, and increases the cost of accessories
2. The heat preservation of the paint pipeline is in the form of hot water, but only the heating measures are taken for the section from the mixing pump to the mixer, and there is no heating measure between the A and B material tanks and the mixing pump, so that when the second When working for the first time, the A and B materials between the A and B material tanks and the mixing pump are not well heated and kept warm, which will cause uneven mixing for a period of time at the beginning of the system, resulting in unnecessary waste of paint and product quality. question
In addition, the thermal insulation performance and efficiency of the system are low. Before spraying, the paint is only heated with hot water. When the paint reaches the predetermined temperature, it needs to be preheated for a long time in advance, resulting in high energy consumption and inconvenient on-site operation.
3. Coating ratio The main pump is a fixed volume ratio (2.33:1), and the scope of application of the coating ratio is narrow, which cannot fully adapt to the ratio of the types of fire-resistant coatings used in current projects.
In addition, the spraying pressure is low (52:1), so it will be very difficult to spray paint with relatively high viscosity, so the adaptability is poor
4. Before the construction of the fire retardant coating, it needs to be stored in the air-conditioned insulated container for too long (about 24 hours) and the temperature is too high (30 to 33°C), which leads to low efficiency and high energy consumption.

The dual-component high-pressure proportion-adjustable fire retardant coating spraying device comprises a control mechanism, a main air feed pump, a feeding mechanism, a heating mechanism, a proportioning mechanism, a spraying mechanism and a cleaning mechanism. The control mechanism is a digital electronic controller, the input end of the main air feed pump is connected with an external air source, the output end of the main air feed pump is connected with the feeding mechanism, the heating mechanism, the proportioning mechanism, the spraying mechanism and the cleaning mechanism through an air pressure adjusting device, and a switch of the main air feed pump is connected with a main air switch of the digital electronic controller. The dual-component high-pressure proportion-adjustable fire retardant coating spraying method includes the steps of adding A-component coatings and B-component coatings into an A-component coating bucket and a B-component coating bucket; heating the A-component coatings, the B-component coatings and coating pipes; when the temperature of the A-component coatings and the temperature of the B-component coatings reach the set temperature, adjusting the proportion of the A-component coatings to the B-component coatings, and carrying out proportion testing; mixing the A-component coatings and the B-component coatings through a far end mixer; adding the A-component coatings and the B-component coatings which are completely mixed into a mixed coating pipe; carrying out spraying; cleaning the device after spraying is completed; stopping the device. The spraying efficiency is high, and the coating quality is good.

Description

technical field [0001] The invention relates to a two-component, high-pressure, adjustable-ratio fireproof paint spraying equipment and method. Background technique [0002] At present, many brands of fireproof coatings (Chartek.Chartek1709.FiretexM90.Pitt-charXP, etc.) have been widely used in the field of marine engineering, and the demand for spraying equipment is increasing. Due to the high viscosity of the fire retardant coating, the construction temperature of the material needs to be kept at 50 to 60°C, so the performance requirements of the construction equipment are relatively high, and the spraying method is also relatively complicated.
