Problems solved by technology

[0004] In the actual operation process of the existing coating process, the degreasing process is completed in one step. If the temperature of the degreasing liquid drops too fast, the degreasing effect will be deteriorated. The processed raw materials have poor anti-corrosion ability and short anti-corrosion time. Phosphorus and other harmful chemicals need to be used. For this reason, we propose a surface coating process for fire-fighting equipment processing

Embodiment 1

[0031] see Figure 1-2 , a surface coating process for fire-fighting equipment processing, comprising the following steps:

[0032] S1: Pre-degreasing treatment. The surface of the fire-fighting equipment is rinsed by a flushing device. The water temperature is 60°C, the flushing time is 1min, and the flushing pressure is 0.15Mpa. The degreasing liquid is sprayed on the surface of the fire-fighting equipment by the flushing device for pre-degreasing For treatment, the degreasing liquid is made of degreasing agent mixed with water, the temperature of the degreasing liquid is 50°C, the free alkalinity of the degreasing liquid is 25pt, the spraying pressure is 0.15Mpa, and the spraying time is 1.5min;

[0033] S2: Main degreasing treatment. The fire-fighting equipment treated in S1 is immersed in a degreasing tank filled with degreasing liquid for degreasing soaking treatment. There is a stirring device inside the tank to ensure that the degreasing tank liquid is even and in con...

Embodiment 2

[0047] see Figure 1-2 , a surface coating process for fire-fighting equipment processing, comprising the following steps:

[0048] S1: Pre-degreasing treatment. The surface of the fire-fighting equipment is rinsed by a flushing device. The water temperature is 80°C, the flushing time is 1min, and the flushing pressure is 0.18Mpa. The degreasing liquid is sprayed on the surface of the fire-fighting equipment by the flushing device for pre-degreasing For treatment, the degreasing liquid is made of degreasing agent mixed with water, the temperature of the degreasing liquid is 70°C, the free alkalinity of the degreasing liquid is 35pt, the spraying pressure is 0.18Mpa, and the spraying time is 1.5min;

[0049] S2: Main degreasing treatment, immerse the fire-fighting equipment after S1 treatment in a degreasing tank filled with degreasing liquid for degreasing soaking treatment, the free alkalinity of the degreasing liquid is 30-40pt, the temperature of the degreasing liquid is 70...

Embodiment 3

[0063] see Figure 1-2 , a surface coating process for fire-fighting equipment processing, comprising the following steps:

[0064] S1: Pre-degreasing treatment. The surface of the fire-fighting equipment is rinsed by a flushing device. The water temperature is 70°C, the flushing time is 1min, and the flushing pressure is 0.17Mpa. The degreasing liquid is sprayed on the surface of the fire-fighting equipment by the flushing device for pre-degreasing For treatment, the degreasing liquid is made of degreasing agent mixed with water, the temperature of the degreasing liquid is 58°C, the free alkalinity of the degreasing liquid is 28pt, the spraying pressure is 0.17Mpa, and the spraying time is 1.5min;

[0065]S2: Main degreasing treatment. Immerse the fire-fighting equipment after S1 treatment in a degreasing tank filled with degreasing liquid for degreasing soaking treatment. There is a stirring device inside the tank to ensure that the degreasing tank liquid is even and in con...

Abstract

The invention relates to the technical field of fire-fighting equipment, and discloses a surface coating process for processing fire-fighting equipment. The process comprises the following steps of S1, pre-degreasing treatment; S2, main degreasing treatment; S3, clear water treatment; S4, activating treatment; S5, secondary water washing; S6, silane treatment; and S7, drying treatment. According to the scheme, operation is easy, an adopted treating agent is stable in performance and environmentally friendly, phosphorization and chromaking technologies are effectively replaced, the dead corners of the fire-fighting equipment can be effectively cleaned, the problem that the coating efficiency is low due to the fact that rust and surface oxidation films cannot be completely cleaned due to the fact that some dead corners cannot be polished is solved, through processing of the primer in the coating step and the polishing step, the roughness of the outer surface of a machined part is changed while the internal micro-structure of the machined part is modified, so that primer adhesion is facilitated, and meanwhile, the primer layer is polished again, so that the adhesion effect of finish paint can be improved.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to a surface coating process for processing fire-fighting equipment. Background technique [0002] Firefighting tools refer to some equipment used for firefighting. There are many kinds of firefighting tools, such as: fire axes, fire hydrants, fire barrels, fire hooks and so on. Firefighting tools should be checked regularly by custodians. In order to do a good job in firefighting work, extinguish fires in time, and prevent accidents, strictly strengthen the management of firefighting facilities and firefighting equipment. Firefighting equipment is the most important fire extinguishing tool at the fire scene, and correct mastery and use of firefighting equipment will play an irreplaceable role in reducing casualties and property losses in fires. Therefore, the correct use of various fire-fighting equipment is an extremely important part of fire-fighting work. [0...
