摘要:
A thermally diffusible composite comprising a thermally diffusible medicine such as allethrin, a thermogenic composition including an alkali metal sulphide or the like, carbonaceous material or the like and, if desired, a filler such as cellulose. In one embodiment, this invention relates to such a thermally diffusible composite the thermogenic composition or the whole of which is enclosed in an oxygen-impermeable container.
摘要:
An improved mosquito coil composition comprising from 72-83% by weight based on dry ingredients of a carrier selected from sawdust having a particle size between 70 and 200 mesh, coconut shell flour, pyrethrum marc, and mixtures thereof, from 16-26% by weight based on dry ingredients potato starch and 0.5-3% by weight based on dry ingredients of an insecticide. The process comprises dispersing the starch in water heated to a temperature of from 40.degree.-65.degree. C., adding water having a temperature of between 80.degree.-95.degree. C. to the dispersed water-starch mixture, mixing the starch-water gel with the filler and insecticide, extruding the mixture into a ribbon, forming the mosquito coils from this ribbon, and drying the formed mosquito coils.
