Introduction of failure causes of flame retardants after use

Flame retardant is a functional additive that imparts flame retardant to flammable polymers. Can be widely used in fabric, wood, plastic, rubber, polyurethane and other flame retardant. Sometimes, flame retardants fail when applied. So what is the reason why flame retardants fail after they are used? Now let's introduce it.
1. Different flame retardants. Different flame retardants have different maintenance times, such as the failure time of disposable flame retardants and durable flame retardants; The flame retardant effect and failure time of water - based flame retardant and flame retardant varnish are different. Obviously, fire retardant varnish treated wood fire retardant effect and effective time longer.
2. The use of flame retardants. There are two types of flame retardants: internal and external. Adding is adding flame retardant before forming flame retardant, mixing and stirring to form, plus soaking and spraying flame retardant by physical methods. Obviously, the longer you put flame retardants in there, the better.
3. Environmental factors. The effective time of treated flame retardants varies depending on the environment in which they are stored (placed). For example, due to the influence of outdoor sunlight, temperature and air, the failure speed of outdoor is obviously faster than that of indoor.
4. Flame retardant treatment time is too long. If the distance from the last flame retardant treatment more than half a year, the flame retardant effect will be more than the flame retardant start time difference or ineffective.
