Description
Technical field
The present invention relates to the process to fire extinguishing protective garment outer layer of the security against fire field, be specifically related to a kind of method improving fire extinguishing protective garment outer layer water permeability resistance and recovery outer layer original appearance.
Background technology
Fire extinguishing protective garment can protect fireman not encroached on by flame and radiant heat, and fire extinguishing protective garment includes outer layer, waterproof ventilative layer, thermal insulation layer and comfort liner. Relevant criterion requires that outer layer has certain surface moisture resistance (spray rating >=3 grade), but the water permeability resistance of outer layer is not required, and simply the water permeability resistance of waterproof ventilative layer has been done requirement, for the poisture-penetrability of outer layer also without being required. In actually used process, the water of fire-fighting lance ejection is easy to splash fireman after reflection or refraction and puts out a fire on protective garment outer layer, even penetrates outer layer and enter on waterproof ventilative layer, can along the downward diffluence in the surface of waterproof ventilative layer at these water of normal temperature environment, but these water can build-up ice quarrel at low ambient temperatures, even makes protective garment become nilas and affect Operational Effectiveness Rat. Therefore, the Research Significance of the freezing ability particularly water permeability resistance of fire extinguishing protective garment is great, the present invention is directed to this problem and proposes a solution, to improving fireman's Operational Effectiveness Rat under cold district low temperature environment.
Summary of the invention
The current research for fire extinguishing protective garment outer layer water permeability resistance is less, and the present invention proposes a kind of method improving fire extinguishing protective garment outer layer water permeability resistance and recovery outer layer original appearance with regard to this. The method processes through powerful glue spraying, glazing wax spray processes and first time waterproof spray processes, it is possible to improve its water permeability resistance (hydrostatic pressing brings up to 5-8kPa) further when keeping superficies moisture resistance (spray rating >=4 grade). Impulsive force after hydraulic giant reflection or refraction can weaken significantly, and when this part water splashes fire extinguishing protective garment outer layer, owing to the outer layer after processing has higher surface moisture resistance, the water being bonded at outer layer can be eliminated along outer layer landing. Owing to the outer layer after processing has a higher water permeability resistance, and then eliminate major part and penetrate the water of outer layer. Therefore the fire extinguishing protective garment outer layer of high surface moisture resistance and high water permeability resistance has certain freezing ability, although poisture-penetrability declines to some extent after processing simultaneously, but does not affect fire extinguishing protective garment use at low ambient temperatures. When protective garment of putting out a fire needs to use under normal temperature environment, glue spraying, wax spray and spray can be removed by abluent, recover poisture-penetrability and the water permeability resistance of outer layer, and process, by second time waterproof spray, the surface moisture resistance recovering outer layer, and then recover the original appearance of outer layer.
The present invention adopts the technical scheme that: a kind of method improving fire extinguishing protective garment outer layer water permeability resistance and recovery outer layer original appearance, it is characterised in that the method comprises the following steps:
Step one: powerful glue spraying processes
Using powerful glue spraying that the outer layer of fire extinguishing protective garment is vertically sprayed, jet length is 0.1-0.3m, and injection duration is 1-2s, and injecting times is 1-3 time, and each interval time is 10-20s, obtains the fire extinguishing protective garment outer layer after powerful glue spraying processes;
Step 2: glazing wax spray processes
Powerful glue spraying places 300-400s after processing, glazing wax spray is used to continue the outer layer of fire extinguishing protective garment is vertically sprayed, jet length is 0.1-0.3m, injection duration is 2-5s, injecting times is 1-2 time, each interval time is 10-20s, then uses rag to smear uniformly, obtains the fire extinguishing protective garment outer layer after glue spraying, wax spray process;
Step 3: first time waterproof spray processes
500-700s after wax spray process, use hair-dryer that glue spraying, wax spray are solidified, then 1800s-3600s is waited, waterproof spray is used to continue the outer layer of fire extinguishing protective garment is vertically sprayed, jet length is 0.1-0.3m, and injection duration is 2-3s, and injecting times is 1-2 time, each interval time is 5-10s, obtains the fire extinguishing protective garment outer layer after glue spraying, wax spray, first time waterproof spray process;
Step 4: abluent processes
Fire extinguishing protective garment outer layer tiling after glue spraying, wax spray, first time waterproof spray are processed, then abluent is used vertically to spray, jet length is 0.1-0.2m, and injection duration is 3-5s, and injecting times is 1-4 time, every minor tick 1-2s, obtain the fire extinguishing protective garment outer layer of abluent spraying, then manually rub, and be positioned in water and wash, obtain the fire extinguishing protective garment outer layer after removing glue spraying, wax spray, spray, and be dried;
Step 5: second time waterproof spray processes
By dry fire extinguishing protective garment outer layer tiling, using waterproof spray vertically to spray, the distance of injection is 0.1-0.3m, injection duration is 2-3s, injecting times is 1-2 time, and each interval time is 5-10s, has finally recovered the original appearance of fire extinguishing protective garment outer layer.
Fire extinguishing protective garment outer layer is carried out powerful glue spraying process with having the benefit effect that by advantages of the present invention, it is possible to raising processes the water permeability resistance at position (area more than 95%); The process of glazing wax spray solves water permeability resistance in powerful glue spraying processing procedure on the one hand and improves to obtain problem of non-uniform, also reduces the viscosity processing position glue spraying on the other hand, the water permeability resistance of comprehensive raising process position (area 100%); Processed by waterproof spray and improve the surface moisture resistance that powerful glue spraying processes and glazing wax spray process position reduces, and then the fire extinguishing protective garment outer layer of be maintained original surface moisture resistance (spray rating >=4) and water permeability resistance raising (hydrostatic pressing is up to 5-8kPa), fire extinguishing protective garment after so processing has higher water permeability resistance and surface moisture resistance, and then there is certain freezing ability, can effectively alleviate chance water freezing problem when low temperature environment uses. Adopt this method can also recover the original appearance of fire extinguishing protective garment outer layer, it is simple to fire extinguishing protective garment being continuing with under normal temperature environment simultaneously, and do not affect its poisture-penetrability. Glue spraying, wax spray and spray can be removed by the process of abluent, and processing, by second time waterproof spray, the surface moisture resistance that can recover to reduce because of process, waterproof spray processes does not affect the fire extinguishing hardness of protective garment outer layer, fire resistance, physical property etc. In a word, the present invention is favorably improved fireman's Operational Effectiveness Rat under cold district low temperature environment, can also recover the original appearance of fire extinguishing protective garment outer layer simultaneously, it is ensured that the fireman's normal use under non-cryogenic environment.
