Application Study Of BL-environmental Concerned Fire-retardant In Particleboard

The research firstly digests, absorbs and innovates the overseas technique, then through a great deal of improvement and small trial, gains the scientific research fruit: BL-environmental concerned fire-retardant which is used to manufacture fire-retarded Particleboard with environmental concern. Study goes together with doing adaptabilitic experiment of BL- environmental concerned fire-retardant and urea resin. And made use of the liquid and solid fire-retardant to manufacture particleboard. Examining the oxygen index number, formaldehyde emission, internal bond strength etc. various function. Make sure the using quantity of fire-retardant and urea resin, and hot pressing technics condition. At the same time, particleboard is treated with BL-environmental concerned fire-retardant. Then the excellent processing method and consistence of fire retardant are elementary confirmed.In study process, utilize orthogonal experiment design to analyze the technology. With the help of oxygen index apparatus, formaldehyde apparatus, environment scanning electron microscope (ESEM) etc., and interrelated experiment measures, the following main results are obtained.1. BL-environmental concerned fire-retardant has three very obviously innovation points.The method that the usage reaction kettle produce is initiated at home and abroad;The cost is lowest,and is a local of the same kind product of 1/2~2/3;The composition of environmental concerned fire-retardant is not polyphosphate amine, elementary authenticated for a differential phosphorus-nitrogen series liquid reagent.2. BL-environmental concerned fire-retardant is phosphorus-nitrogen series liquid reagent that has many virtues such as a high concentration,environmental concern, innocuity one reagent with two functions, low cost, easiness to produce and use. Because it...
