Red phosphorus flame retardant - Names and Identifiers
Red phosphorus flame retardant - Introduction
Red phosphorus is a common flame retardant with the following properties:
1. Physical properties: Red phosphorus is dark red crystal, amorphous and fixed two forms. At room temperature, red phosphorus is more stable, but when the temperature exceeds 240 ℃, red phosphorus will be ignited by oxygen.
2. Flame retardant performance: Red phosphorus has good flame retardant effect, can effectively prevent the flame and oxygen supply. It can be added as a flame retardant to plastics, rubber, coatings and textiles and other materials to improve its flame retardant properties.
3. Preparation method: There are two main methods for preparing red phosphorus flame retardant. The first is to extract red phosphorus directly from natural phosphate rock. The second is the preparation of red phosphorus by oxidation of white phosphorus.
4. Use: Red phosphorus flame retardant is widely used in all kinds of materials, especially polymer materials, such as plastic, rubber and so on. It can significantly improve the fire resistance of these materials and reduce the occurrence of fire accidents.
5. Safety information: Red phosphorus is a toxic substance, the skin and respiratory tract irritation, inhalation of red phosphorus dust may lead to poisoning. When handling red phosphorus, pay attention to wearing personal protective equipment such as protective gloves, masks and glasses, and ensure that the operating environment is well ventilated. When storing and using red phosphorus, keep away from fire and flammable materials. In the treatment of waste red phosphorus, appropriate methods should be adopted to avoid environmental pollution.
Please carefully read and follow the relevant safety procedures when using red phosphorus flame retardant to ensure safe use.
