Henan Jutai Door Industry (steel wood fire door, wooden fire door, steel fire door, fire shutter door) is a kind of industrial and trade enterprise that integrates R&D, production, sales and service. Why can we prevent fire? We know the fire door. There are two kinds of wooden fire doors and steel fire doors. The steel door fire is well understood. How can this wooden fire door be fireproof? Some consumers don't understand it. Let's take a look at the process comparison; The flame retardant quality of wood is related to the fire endurance of wooden fire doors. Therefore, many fire door manufacturers have set up this process as a special process control point in the production process, but due to the lack of mature process regulations in the flame retardant process, the various manufacturers Zhejiang The fire-retardant process of wooden fire doors is different, the flame-retardant process is not reasonable, and the flame-retardant quality cannot be guaranteed. In severe cases, the fire-resistance limit of fire doors is reduced, which poses potential hidden dangers to the lives and property of the people.

Commonly used flame retardant methods for wood are: spraying method, soaking method, cooking method, vacuum method, vacuum pressing method, and the like. The spraying method and the immersion method are generally applied to the surface of wood which is no longer shaved, and the flame-retardant treatment of the sheet having a thickness of less than 10 mm, and is not suitable for the production of wooden fire doors. Although the vacuum method and the vacuum press method have excellent flame retardant effects, they are not used in some fire door manufacturers because of their high equipment.
At present, most fire door companies use the cooking method for flame retardant treatment. Jutai Industry believes that the wood-insulated fire-proof door should pay attention to the following points when using the cooking method for flame-retardant treatment: the moisture content of the wood to be fire-retardant is not important. The moisture content of the fire retardant wood is an important factor affecting the flame retardant quality of the wood. factor. Because the dried wood is more likely to absorb the flame retardant after entering the flame retardant pool, the amount of flame retardant absorbed by the wood directly affects the flame retardant quality of the wood, and its absorption is proportional to the oxygen index and flame retardant depth of the flame retardant wood. relationship. The more wood absorbs the flame retardant liquid, the better the flame retardant performance of the wood, the higher the oxygen index and the deeper the flame retardant depth. However, many companies believe that wood is still wetted by flame retardant liquid when it is flame retardant. Therefore, the moisture content of wood has little to do with low point. The wood to be fire-retarded is generally not dried, and some enterprises will even The wet wood that has just been sawed is flame retardant. I do not know that the moisture content of wood will affect the flame retardant quality, resulting in unstable flame retardant quality of fire retardant wood. According to the test, under the same flame retardant conditions, wood with a moisture content of less than 15% can be increased by more than 5 oxygen indexes and wood flame retardant depth by more than 3 mm.
