Problems solved by technology

When firefighters participate in the fire fighting and rescue process, the burning environment is complex and changeable. It has been found in domestic and foreign reports that the pollution of PAHs remains in the fire fighting protective clothing. Due to the toxicity, genotoxicity, mutation and carcinogenicity of PAHs, it can cause serious Various hazards, such as damage to the respiratory system, circulatory system, and nervous system, and damage to the liver and kidneys
At present, there is no efficient targeted cleaning agent and cleaning process for the cleaning of PA Hs in fire-fighting protective clothing, especially for the removal of pollution in multi-layer structures.

Abstract

The invention provides a special cleaning agent for PAHs pollution of fire-extinguishing protective clothing as well as a preparation method and application of the special cleaning agent. Every 100 parts of the cleaning agent comprises the following components in parts by weight: 5-20 parts of a surfactant X1; 1-6 parts of a surfactant X2; 4 to 8 parts of a surfactant X3; 1-3 parts of a dispersant; 1-10 parts of an organic solvent; 0.5 to 1.5 parts of an enzyme preparation; and the balance of water. The special cleaning agent can remove residual PAHs on the surface and the inner layer of the fire extinguishing protective clothing in a targeted manner, and PAHs molecules are fully captured through the emulsification effect of nonionic surface activity in the formula and the dissolving capacity of the organic solvent.

Description

technical field [0001] The invention belongs to the field of cleaning agents, and in particular relates to a special cleaning agent for PAHs pollution of fire-fighting protective clothing and a preparation method and application thereof. Background technique [0002] Polycyclic aromatic hydrocarbons (PAHs for short) are carcinogenic pollutants and belong to semi-volatile fat-soluble compounds. Most of them are produced after insufficient combustion of organic plastics. In the process of firefighters participating in firefighting and rescue, the combustion environment is complex and changeable. Reports at home and abroad have found that the pollution of PAHs remains in firefighting protective clothing. Due to the toxicity, genotoxicity, mutagenicity and carcinogenicity of PAHs, it can cause damage to the human body. A variety of hazards, such as damage to the respiratory system, circulatory system, nervous system, and damage to the liver and kidneys. At present, there is no ...
