WebOct 1, 2024 · When the concentration of flammable gas reaches the UFL, the oxygen content in the environment will become very low. If the content of the flame retardant is slightly increased, the flammability of R1234yf will be significantly suppressed. When the oxygen concentration drops to 16.0%, the LFL and UFL will become one point. Web136 rows · Temperature, pressure, and the concentration of the oxidizer also influences flammability limits. Higher temperature or pressure, as well as higher concentration of the oxidizer (primarily oxygen in air), results in lower LFL and higher UFL, hence the gas …
WebYes, flammability is a chemical property. We know this because burning something results in a chemical change (for example, creating carbon dioxide for burning carbon in oxygen or water from burning hydrogen in oxygen) that is not easily reversible. WebFlammability is related to the safety of clothing and textile products, which are closely related to our daily life because flammability of textiles can directly lead to serious bodily injury or fatality and loss of property.
