The density of the spiral material is 0,4 to 0,7 kg/dm3, and the spiral is coated with the active ingredient. The average size of the wood chips is between 2 x 0,5 x 0,1mm and 10 x 3 x 2mm. The average length of fibres is between 3mm and 15mm. The wood chips/fibres are compressed into panels. A pressure is used, which produces panels, which have the mentioned density when dry. The coils are coated with the active ingredient, by rollers, before or after stamping out. USE/ADVANTAGE - Mosquito coil of simple mfr. does not break, is lightweight and smooth, permits active ingredient to be very effective. |
