Problems solved by technology

The disadvantage of the former is that the burning speed is unstable and occupies a large area. Although the latter avoids the disadvantages of the former, it has caused new problems. To ensure that the ignition powder is pressed on the main charge, the required amount of ignition powder is large and the process is complicated

Embodiment Construction

[0021] With reference to accompanying drawing, specific embodiment of the present invention is: under normal temperature and pressure, selects under the 100 mesh sieves of particle size, and purity is ten groups (55%, 58%, 60% in the potassium perchlorate weight ratio 55-75% of 98%) . Ten groups (45%, 42%, 40%, 38%, 36%, 35%, 33%, 30%, 38%, 25%) correspond to each other in 45%, and the sum of the weight ratios of each group is 100%. At room temperature and normal pressure, mix the above-mentioned ten groups of potassium perchlorate and fine spherical aluminum powder to form ten groups of solid materials, and set aside; then take the active energy binder solution weight ratio (addition) 2%, the active energy The proportion of components contained in the adhesive solution is: 30-40 grams of nitrocellulose is divided into ten groups (30 grams, 31 grams, 32 grams, 33 grams, 34 grams, 35 grams, 36 grams, 37 grams, 38 grams, 39 grams , 40 grams), respectively mixed with 1 liter of ...

Abstract

The invention provides a detonation and ignition charge in extinguishing devices and its coating process, which comprises mixing potassium perchlorate and fine ball-type aluminum dust into solid article, mixing with external adhesive solution, coating onto the main charge and ignition surface, then air-drying.

Description

1. Technical field [0001] The invention relates to a starting ignition powder in a fire extinguishing device, in particular to a coating process of a novel high-energy ignition powder. 2. Background technology [0002] So far, the high-energy ignition powder composed of potassium perchlorate and aluminum powder is mainly combined with the main charge in two forms. One is placed on the main charge in the form of bulk pressing, and the other is mixed with a binder and made into granules by forced sieving, and then placed on the main charge and mixed with the main charge. Press together. The disadvantage of the former is that the burning speed is unstable and occupies a large area. Although the latter avoids the disadvantages of the former, it has caused new problems. To ensure that the ignition powder is pressed on the main charge, the required amount of ignition powder is large and the process is complicated. 3. Contents of the invention [0003] The purpose of the prese...
