Fire prevention of the hottest paint production pr

Fire prevention of paint production process

paint is also called paint. In the early days, paint was made of oil and paint, but now the paint used is chemical products, usually composed of oil, phenol, resin, pigment, solvent, etc

I. fire hazard

1. The production of paint must use xylene, alkyd resin, nitrocellulose paint solvent, nitrocellulose and other flammable and explosive organic substances. The whole production process needs to be heated at many places, and a little carelessness can cause a fire

2. During the use of paint, the commonly used solvents are gasoline, toluene, xylene, trichloroethylene, etc. when treated with open fire or sprayed with air 13 concrete pumping agent, some coatings that diffuse with the air greatly increase the risk of fire. In addition, the high-voltage static electricity generated during electrostatic spraying and the open fire heat source used for heating during drying all pose great fire hazards

II. Fire prevention measures

1. Paint production

during the production of alkyd resin varnish, it is necessary to strictly follow the operating procedures, control the heating rate, accurately connect the proportion and feed, so as to prevent the boiler from rising and overflowing caused by too fast heating rate or too much feeding. In order to accurately measure the temperature, it is better to equip two sets of temperature measuring devices on the reaction kettle, which should be interlocked with the heating system. When heating with gas, you should ignite first and then turn on the gas. The reaction kettle heated by open fire should be tested regularly and replaced in time. It is strictly forbidden to contain water when adding xylene. The content of wetting agent in plastic bag or iron bucket used as wetting agent should reach 3O%. When using, it should adhere to the principle of "first in, first out" and should not be stored for a long time. When using in the workshop, it should be received as soon as it is used, and it should not exceed the consumption of one shift. When taking it, handle it with care, and do not use ferrous tools to take it out. The scattered nitrocellulose lint and dust should be treated in time. Nitrocellulose should not be exposed to organic limbs and oxidants, especially m-phenylenediamine. When grinding, pay attention to ventilation to prevent steam accumulation. It is best to install a combustible gas alarm device. When mixing paint, it is necessary to observe the feeding sequence. It is best to select pieces of material with smaller particles as the "king of new materials" to avoid blockage during feeding, such as modifying experimental data. Before adding pieces of material, first unplug the pipe conveying solvent to the mixing drum, so that the pieces of material are easy to fall into the mixing drum. If there is blockage, do not use iron to dredge it

2. Paint use

(1) when using flame for surface treatment of paint, prevent "boiling over", and the equipment should be kept in good condition to prevent running, emitting, dripping and leakage. When adding turpentine, the flow rate should not be too fast to prevent static electricity. The filtration pressure should not exceed o.o25 MPa. The filter cloth should be cleaned regularly. After being discarded, the sample should be clamped on the tensile machine to measure the stripping force of each point. The filter cloth should be properly handled. The filter plant should be well ventilated and no open fire is allowed

(2) during the production of color paint, it is strictly forbidden to use iron tools to open the bucket cover containing thinner and semi-finished products; Cotton yarn and other objects with thinner shall not be thrown around, but shall be placed in a covered iron bucket; Motor vehicles entering the workshop should wear spark arresters, and electrical equipment should meet explosion-proof requirements
