As we all know, most of the traditional high-molecular decorative materials are easy to be ignited and produce harmful gases. Also, PU materials are no exception. But, it is truly difficult to put out the fire when the air is well-circulated. Therefore, in order to reach the national fireproof standard, we have made great efforts to our PU Decorative Materials.
Methods for PU materials are as follows:
Method 1: Adding Fire Retardants
Currently, adding fire retardants is the most popular way to get a satisfied effect. It refers to adding a certain proportion of fire retardants in the production process of PU decorative materials. Common fire retardants include Halogenated phosphate, dimethyl methylphosphonate, melamine and so on. Some of them are added to liquid raw materials, and the others are added before or during foaming. In this way, the best fireproof effects can be realized.
These two fire retardants are frequently used by H&K Goodware:
1 Liquid fire retardant.
It is added to the PU material by mechanical mixing, which has a plasticizing effect. Unfortunately, it is easy to volatilize after a long-term use.
2 Powder fire retardant.
Added by mechanical mixing, this fire retardant can be well integrated with the raw materials. And then it makes our PU materials a little bit heavier but gives it permanent fire resistance.
Method 2: Spraying Fireproof Coatings on the Surface
We often spray fireproof coating on the surface of PU decorative materials Because these kind of coatings will exert an special effect on the surface, which could slow the fire spread. As a result, we could get a satisfied fireproof effect.
Method 3: Fireproof Preparations Designed in the Beginning
We all know that electrical fire is dangerous safety hazard, which is often caused by electrical short circuit, over load, aging of the circuit, and so on. So, H&K GoodWare® pays high attention on this problem. We cultivate our construction team in a quite high standard, and require them to take fire precaution measures during working. Such as using appropriate materials for different type of products to reach fireproof.
It is significant to select the right raw materials for decoration. Because when the fire happens, we could win valuable time for rescue if the decorative materials are fireproof. Therefore, selecting the right material is closely-related to our health and safety.
