Common sense of paint: the danger of paint

Core tip: paint, which belongs to class 3.2 or 3.3 flammable liquid in hazard code, is toxic Its characteristics are: 1 Highly flammable: the reason is that almost all flammable liquids are organic compounds, and the molecular composition mainly contains carbon and hydrogen atoms, which are easy to react with oxygen and burn And the flash point is low and the ignition point is also low, so it is easy to ignite and burn 2 Flammable liquid is highly volatile When the container containing the liquid is damaged or unsealed, the volatile flammable vapor diffuses to the whole space of the warehouse or compartment where the article is stored or carried, and mixes with air Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: paint, belonging to class 3.2 or 3.3 flammable liquid in the dangerous regulations, is toxic Its characteristics are as follows: 1 High flammability: the reason is that almost all flammable liquids are organic compounds, and the molecular composition mainly contains carbon and hydrogen atoms, which are easy to react with oxygen and burn And the flash point is low and the ignition point is also low, so it is easy to ignite and burn 2 Flammable liquid is highly volatile When the container containing the liquid is damaged or unsealed, the volatile flammable vapor diffuses to the whole space of the warehouse or compartment where the article is stored or carried, and mixes with air When the concentration reaches a certain range, i.e reaches the explosion limit, it can cause explosion in case of open fire or spark 3 The molecule and viscosity of flammable liquid are generally very small, which is not only easy to flow, but also because of the penetration, infiltration and capillary phenomenon Even if the container has only very small cracks, the flammable liquid will leak out of the container wall, expand its surface area, and constantly volatilize, so that the concentration of flammable liquid vapor in the air increases, thus increasing the risk of combustion and explosion Risk 4 The expansion coefficient of flammable liquid is relatively large due to its thermal expansion, and the volume is easy to expand after heating Meanwhile, its vapor pressure also increases, so that the internal pressure in the sealed container increases, resulting in "drum" or even explosion There is more than 5% space in the container, which cannot be filled 5 Toxicity, flammable liquid and its vapor have different degrees of toxicity, not only inhalation of its vapor will be toxic, some through the skin absorption will also cause poisoning accidents Identify the types of accidents: fire and explosion, poisoning, container bursting Emergency measures for fire fighting: use foam, carbon dioxide, dry powder, sand to extinguish fire, and fog water to cool the container in the fire First aid: the patient who inhales the steam should be removed from the contaminated area Rest and keep warm Wash eyes with irritant water Send patients to hospital for treatment Skin contact is scrubbed with solvent and then thoroughly washed with soap Wash your mouth immediately and send to hospital for treatment Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
