METHOD OF PRODUCING AN IGNESCENT MATERIAL

摘要

Ignitor comprises a thin layer of porous mainly mechanical pulp which is soaked with a flammable organic substance e.g. paraffin. The pulp which is at least 50% mechanical pulp is machine dried under light pressure to form a thin layer having a thickness of 1-4 mm. The density is 150-450 kg/m3. The flammable substance contains less than 1% of non paraffinic hydrocarbons. It has a melting point or melting point interval of 52-54 deg.C. After impregnation and cooling, the material is cut into pieces. Before use these are torn into smaller pieces. (Provisional basic previously advised in week 8505)
