The main problems of fire retardant coatings in China
For example, the production scale of most enterprises is not large, the level of process automation is not high, and the formulation process of many products is similar, lacking intrinsic characteristics; insufficient research on raw materials dedicated to fireproof coatings, lack of resin dedicated to intumescent fireproof coatings; Coating production and construction equipment is not matched; fireproof coatings are applied in engineering, and there are problems in the selection of types and types, the determination of the thickness of protective layers, the supervision of construction quality, and the maintenance and repair during use.
According to the similar technical experience of foreign developed countries and the higher requirements put forward by the majority of users in China, there are still some gaps and problems in the development and application of fire retardant coatings.
In the actual work, it was found that the fire-retardant supervision of various decorative surface materials in the current fire protection law enforcement still stays in the “experience ageâ€, and it is burned by eye, hand touch and lighter. It is undeniable that this method is simple and easy, but its biggest drawback is inaccuracy. It is not sure whether the fire rating is level 1 or 2 after flame retardant treatment, and it is easily blinded by the supervision department: use some counterfeit and shoddy products. Spray and install on the finishing material. At the same time, some entertainment venues are willing to fire-retardant all kinds of combustible decoration, their fire prevention awareness is not strong, there is a sense of luck, and the price of fire retardant coating is high, and the flame retardant effect is also an important reason why they are not willing to use it. .
