Abstract

The utility model provides a yarn paper safe ignition wire used for fireworks and crackers, which is mainly composed of an inner core, a cotton yarn antiwear layer and a paint protective layer, wherein, the inner core is made of gun powder and paper, and the external side of the inner core is covered by the cotton yarn antiwear layer made of twelve to thirty pieces of cotton yarn. The moisture-proof paint protective layer is painted outside the cotton yarn antiwear layer. The utility model has the advantages of wear resistant, anti-fold and moisture-proof performances, beautiful appearance, difficult leakage of the gun powder, difficult flameout in use, low material consumption, high efficiency, good effectiveness, high safety factor in produce process, difficult happening of accidents, and good labor protection condition for working persons.

Description

The tissue paper safety firing cable

The utility model relates to a kind of safety firing cable of fireworks and firecrackers, especially for the tissue paper formula safety firing cable of fireworks production.

Traditional firecracker fuse made of paper adopts artificial or mechanical system is made by paper and gunpowder, promptly wraps in addition afterturn of gunpowder with paper bag, and appearance brushes bonding paste.This fuse because tensile property is poor, can loose medicine, burning velocity instability, thereby can not be used for fireworks production.Safety firing cable commonly used in the fireworks production at present is by tens cottons gunpowder to be wrapped, and coats moisture-resisting lacquer in appearance then and forms.This safety firing cable also has following some weak point: at first, because it directly wraps gunpowder with cotton yarn, though its appearance has the paint overcoat, it is antifriction, not anti-folding not, the leakiness medicine, and humidity resistance is poor, can occur disconnected phenomenon during use; Secondly, in process of production, medicine dirt disperses everywhere, and safety coefficient is little, and is dangerous big, and accident potential is arranged; The 3rd, owing in the production environment a large amount of medicine dirt is arranged, the labour protection difficulty influences the healthy of staff; The 4th, the loss of the large usage quantity of cotton yarn, paint, especially gunpowder is bigger, and gunpowder slatterns about 40%, and labor productivity is lower, thereby cost is higher, deficiency in economic performance.

The purpose of this utility model is to provide a kind of antifriction, anti-folding, not leakiness medicine, tissue paper safety firing cable that humidity resistance is good, low, the easy production of its material consumption, and cost is low, profitable.

Technical solution of the present utility model is: it mainly is made up of inner core, cotton yarn antifriction layer and paints and lacquers protection layer; the inner core of making by gunpowder and paper; its outside is wrapped in the cotton yarn antifriction layer that is made of the continuous yarn of 30--12 root, is coated with outside cotton yarn antifriction layer and brushes the moisture-resisting lacquer protective layer.

The utility model compared with prior art has the following advantages:

The first, antifriction, anti-folding, humidity resistance are good, and the leakiness medicine is difficult for flame-out during use;

The second, material consumption is low, efficient is high, has reduced cost, obtains favorable economic benefit.Owing to adopt fuse made of paper, gunpowder is unlikely to be scattered and disappeared everywhere, and gunpowder can save 40%, and simultaneously, cotton yarn saves 30%, and paint saves 10%;

The 3rd, the safety coefficient height is difficult for having an accident in process of production, and provides labour protection condition preferably for the staff;

The 4th, outward appearance is bright-coloured, attractive in appearance.Because directly with the cotton parcel, gunpowder easily leaks the gunpowder of prior art, thereby color is dim behind the anti-moisture-resisting lacquer of brushing in the end, outward appearance is not beautiful.

Accompanying drawing is the structural representation of the utility model embodiment.

Below in conjunction with accompanying drawing the utility model and embodiment are described in further detail:

The utility model mainly is made up of inner core, cotton yarn antifriction layer and 4 on paints and lacquers protection layer; the inner core that adopts special-purpose machineries to make by gunpowder 1 and paper 2; its outside is wrapped in the cotton yarn antifriction layer by 20 cotton 3 afterturns one-tenth, is coated with outside cotton yarn antifriction layer and brushes moisture-resisting lacquer protective layer 4.

The utility model can be according to the specification of different fireworks, adopt 30 or, 16,12 cottons 3 constitute the cotton yarn antifriction layer of different sizes.The utility model also can be used in the firecracker production.

Claims

1. tissue paper safety firing cable; it mainly is made up of inner core, cotton yarn antifriction layer and paints and lacquers protection layer; it is characterized in that: by the inner core that gunpowder and paper are made, its outside is wrapped in the cotton yarn antifriction layer that is made of the continuous yarn of 30--12 root, is coated with outside cotton yarn antifriction layer and brushes the moisture-resisting lacquer protective layer.
