Problems solved by technology

[0003] The inventor of the present invention has repeatedly studied the raw materials that can be used as the outer tube of fireworks, hoping to develop a paper tube and paper tube that can simplify the necessary complicated procedures when sealing the mud bottom, overcome the existing paper tube and mud bottom. Due to the disadvantage of low impact strength, it is necessary to provide a firework tube with good physical and chemical stability, easy access to raw materials, stable shape, moisture resistance, good safety performance, standardized product specifications, no environmental pollution, and the same effect as the previous fireworks paper tubes. One-time molded fireworks outer tube with bottom and manufacturing method thereof

Embodiment 1

[0021] Put the dried rice straw into a pulverizer and pulverize it into 80-mesh sieve, cut the glass fiber filaments into 30mm pieces, put them into the pulverizer and pulverize them into fine fibers, and dilute polyvinyl alcohol with water at a ratio of 1:10 to form Liquid; take a certain component of calcium sulfate hemihydrate, mix 600# cement and perlite powder and pass through a 100-mesh sieve three times, then add a certain component of filler straw fiber dry powder and liquid polyvinyl alcohol, and then put Stir and mix evenly in the mixer, place a thin steel sheet with a thickness of 12 wires on the inner wall of the self-made special molding die, and place a layer of 80 grams of kraft paper on the inner layer of the thin steel sheet, and finally, take out the mixture in the mixer and inject Into the mold in the molding machine, the outer tube of fireworks with a U-shaped bottom is molded by mold core rotation (the thickness of the center of the U-shaped bottom is 10mm)...

Embodiment 2

[0023] Put the dry bagasse into a pulverizer and pulverize it into 80-mesh sieve, cut the glass fiber into 35mm pieces, put it into the pulverizer and pulverize it into fine fibers, mix the water-soluble starch viscose in a ratio of 1:12 Add water to dilute into a liquid state; take a certain component of calcium sulfate hemihydrate, 600# cement, sepiolite dry powder and mix through a 100 mesh sieve three times, then add a certain component of filler bagasse fiber dry powder and liquid starch viscose Put it into the blender and mix it evenly. Place a thin steel sheet with a thickness of 16 wires on the inner wall of the self-made special molding die, and coat a layer of lubricant on the inner layer of the thin steel sheet. Finally, take out the mixed mixture in the blender. The material is injected into the mold in the molding machine, and the outer cylinder of fireworks with a U-shaped bottom is molded by mold core rotation (the thickness of the center of the U-shaped bottom i...

Embodiment 3

[0025]Put the dry corn stalks into the pulverizer and pulverize them into 80-mesh sieves, cut the glass fiber into 40mm pieces and put them into the pulverizer to pulverize and decompose into fine fibers, dilute the sol with water at a ratio of 1:15 to form a liquid Take a certain component of calcium sulfate hemihydrate, mix 600# cement, perlite powder and sepiolite powder and pass through a 100-mesh sieve three times, then add a certain component of filler corn stalk fiber dry powder and liquid sol, put Stir and mix evenly in the mixer, place a thin steel sheet with a thickness of 20 wires on the inner wall of the self-made special molding die, and place a layer of 80 grams of kraft paper on the inner layer of the thin steel sheet, and finally, take out the mixture in the mixer Inject into the mold in the molding machine, and use the core rotary molding to form the outer tube of fireworks with a U-shaped bottom (the thickness of the center of the U-shaped bottom is 10mm); the...

Abstract

Disclosed is an outer tube of fireworks with bottom, whose characteristics is that its main component are haulm fiber, glass fiber, calcium sulfate, light filler, cement of high level and bond. It is formed by once overall stamp by special machine and natural drying, the product has U-typed bottom, a layer of kraft paper enclosing the outer wall of tube, and its appearance, size and length can be ordered by the size needs of different fireworks products. The invention has the advantages of abundant raw material, advanced technology, excellent chemical and physical stability, stable shape, resistance to humidity, high intension and notable safety, which can be widely used in outer tube of various fireworks products.

Description

technical field [0001] The invention belongs to the field of fireworks materials, and in particular relates to a bottomed fireworks outer cylinder and a method for manufacturing the bottomed fireworks outer cylinder with stem fiber, glass fiber and mineral dry powder as main raw materials. Background technique [0002] In the prior art, the fireworks paper tube generally adopts the traditional production process, that is, the cut multi-layer molding paper is manually rolled into a paper tube of the required specification, and then the fine yellow soil after drying and crushing is manually processed into the paper tube. The bottom cover of one end of the paper tube is tightly sealed. This kind of production process is backward, labor-intensive, time-consuming and labor-intensive, and the production efficiency is very low. At present, many manufacturers have begun to use mechanical reels and mechanically pressed mud bottoms, that is, use multi-layer forming paper through machin...
