Abstract

The invention discloses a novel potassium perchlorate paper firing line for firecrackers. Firing powders of the paper firing line are made of potassium perchlorate, hemp stem carbon and magnesium oxide by mass percent. The production process comprises the following steps of: uniformly mixing the hemp stem carbon with the magnesium oxide by adopting a mixing machine by mass percent, and then uniformly mixing with the potassium perchlorate to obtain the firing powders; twisting the firing powders in the step one with firing line paper into a semi-finished paper firing line by adopting a firing line twisting machine, wherein the usage of the firing powders is 0.8 catty to 1.2 catties firing powders / 1 kilometer firing lines; and starching the semi-finished paper firing line of the step 2, and air drying, cutting and pouring disks after starching to prepare the finished paper firing line. The invention has the advantages of stable performance, safe and reliable production and transport, simple production process, high burning rate, low rate of moisture absorption, low friction sensitivity and low impact sensitivity, and the performance and the selected materials are all in line with standards in China.

Description

technical field

[0001] The invention belongs to the technical field of fireworks and firecrackers, in particular to a novel potassium perchlorate paper fuse for firecrackers. Background technique

[0002] The production of firecrackers has a history of hundreds of years in my country, and the production of paper fuses has long been in the manual production of family workshops, and it has only developed into mechanical production without isolation and close-range operation in recent years. The paper fuse in the prior art is usually prepared by mixing potassium chlorate and miscellaneous charcoal according to a certain ratio, and the glue used during pulping is polyvinyl alcohol resin. Since potassium chlorate itself has the characteristics of high friction sensitivity and high impact sensitivity, the impact sensitivity and friction sensitivity are both as high as 95%, and some even reach 100%, which leads to a large safety hazard in the production and transportation of paper ...
