Different processing conditions are needed for treating spruce (Piceaa sperata)o f differentd ensities, with BL-environmentally friendly flame retardant.

This article introduced BL-environment friendly flame-retardant excogitated by wood-based synthetic board research center of BEIJING Forestry University.

This study is one part of my mentor’s item,mainly studies on the technology and method of producing flame-retarded particleboard with environmental concern and environment friendly particleboard using two new-fashioned research fruits: BL-formaldehyde scavenger and BL-environment friendly flame-retardant, and quest for the interrelated principium.

The Application and Study of BL-Environmental Friendly Flame Retardant on the Fabrics for Furnishings;

BL-environmental friendly flame retardant belongs to N-P flame retardant series, and its main raw materials are phosphoric acid and urea the same as ammonium polyphosphate (APP).

Analsysis on retardant properties of fire-retardant medium density fiberboard(MDF) used BL fire retardant chemical scanning electron microscope,oxygen index instrument,thermogravimetry analyser showed that BL fire retardant chemical was an excellent kind of P-N retardant with advantages such as effective fire retardant and smoke suppressant,easy to operate.
