Abstract
The invention belongs to chemical technology field.Its purpose is to overcome because the shortcoming of sealing the gunpowder explosion that causes and low work efficiency is drawn in consolidating of old technology.The present invention compared with prior art is characterized in that adopting the short hard material coagulating agent of dry powder shape, and consolidating of mixing in proportion of filler drawn the dry powder sealing agent, insert at firecrackers and to draw the back filling and draw admittedly and seal, at room temperature urged naturally to solidify firmly, draw the purpose of sealing admittedly thereby reach through 10-20 hours.
The present invention compared with prior art has the advantage of safety, high efficiency, and work efficiency improves more than 10 times than former technology.
Description
The invention belongs to chemical technology field.
It is to adopt to insert to use after big gun draws manually to beat the way of sealing one by one that consolidating in the existing firecrackers manufacturing drawn sealing tech.Not only dangerous work efficiency but also low often causes and gunpowder explosion causes casualty accident because of beating.
The objective of the invention is to overcome above-mentioned shortcoming, a kind of high efficiency is provided, need not manually beat consolidate to draw sealed new technology.The present invention compared with prior art is characterized in that adopting salt or magnesium chloride (MgCl
2), sodium bicarbonate (NaHCo
3) and the short hard material made such as butter, adopt white cement, quick lime, (Cao) or white lime (Ca(OH)
2), the coagulating agent made such as portland cement, adopt fine sand or silica, calcium carbonate, lightweight carbonic acid etc. to make inserts.To draw the dry powder sealing agent through just making consolidating of dry powder shape after the 80-120 purpose sieve after the above-mentioned material mixing, admittedly draw the dry powder sealing agent and insert at firecrackers and will draw the dry powder sealing agent after big gun draws admittedly and insert around big gun draws above-mentioned, at room temperature urged naturally then to solidify firmly, draw the purpose of sealing admittedly thereby reach through 10-20 hour.The consolidating of above-mentioned composition drawn dry powder sealing agent proportioning and is: short hard material 2-10: coagulating agent 30-160: filler 40-100.
The present invention compared with prior art has the advantage of safety, high efficiency, and work efficiency improves more than 10 times than former technology.
