Description

Firework seat and manufacturing method thereof

Technical field

The invention belongs to the technical field of firework production, and relates to a firework seat and a manufacturing method thereof.

Background technique

As people's festive scenes are gradually shifted from the sound of firecrackers to the sound of firecrackers and the colorful seashore, fireworks are used instead of firecrackers. Since ancient times, fireworks invented by Chinese people have become the world's largest production base. In traditional fireworks production, the launch tube uses a paper tube made of straw. Paper costs account for more than 50%, these papers are basically produced by small paper mills. Due to the protection of the environment, many small plants with a capacity of less than 500 tons have been closed successively over the years. As a result, the relationship between the supply and demand of fireworks paper has changed. In particular, the recent ban on the import of foreign garbage has caused the price of paper for fireworks to rise, and the cost of fireworks manufacturers has also increased to a large extent. Therefore, it also provides an opportunity to replace paper fireworks by pressing fireworks with waste paper and plant fibers.

At present, there are two production methods in the existing technology. At present, in Liuyang, Hunan (the world's largest fireworks production base), the firework seat has traditional (manual) and pressed with calcium carbonate and talc powder (the following is called by locals (Referred to as gypsum block). Both methods have certain flaws.

Traditional paper-made firework seats seem to have no pollution to the environment during use, but the most destructive to environmental pollution during the paper manufacturing process. Because in the papermaking process, a large amount of caustic soda is used to corrode the lignin, leaving the fibrin paper lignin, and then neutralizing with hydrochloric acid to adjust the PH value. The wastewater discharged after filtration is extremely polluting to the environment. Due to the low price of straw paper, the added value is small. Only produced in small factories, small factories can not configure filtering environmental protection equipment.

The gypsum block will produce new pollution when it is made, and it will cause pollution everywhere after use. The process of gypsum block is to press the prepared raw materials to be heated in the mold to dry, if it is heated by electricity, the cost is huge. Had to use the boiler, the heat conduction oil boiler currently used. Because boilers using coal as fuel are more polluting the environment than boilers using oil or steam as fuel. So new sources of pollution are created. At the same time, due to the structure and nature of the raw materials, the seat after firing has no recycling value. No one will recycle it. It takes a long time to degrade in nature, so after the fireworks are fired on holidays, this gypsum is everywhere There is no one to pay attention to it, causing visual pollution to the environment. In many places, the law enforcement part resists the fireworks display. Because of this, most fireworks factories also exclude such fireworks, let alone the use of fireworks for export.

Summary of the invention

The purpose of the present invention is to overcome the shortcomings of the above technology and provide an energy-saving and environmentally friendly, low-cost firework holder and a manufacturing method thereof.

The specific technical solution is:

A firework holder, its various components and their mass percentages are:

Waste paper 8.33%

Orange Rod 66.67%

Reinforcing powder 8.34%

Corn starch 8.33%

PVA 5%

Crosslinking agent 0.25%

Moisture-proof agent 0.5%

Release agent 0.83%

Toughener 1.75%.

Further, the cross-linking agent is borax, the moisture-proof agent is polyethylene wax, the release agent is liquid paraffin, and the toughening agent is polyacrylamide.

A method for manufacturing a firework holder of the present invention includes the following steps:

Step 1. Waste paper, orange rods, and reinforcing powder are put into the mixer and mixed at a low speed;

Step 2. Corn starch, PVA, cross-linking agent, moisture-proof agent, mold release agent, high-efficiency toughening agent are put into the reaction kettle, add about 8 times of water, and stir to heat to 90 degrees for 1 hour;

Step 3. Put in a blender and mix well;

Step 4. Quantitative batching through a kneader;

Step 5. Put in a 260 degree hot mold;

Step 6. The mold is heated and formed; the mold is ready for use.

Compared with the prior art, the beneficial effects of the present invention are:

The firework holder for cold pressing of waste paper and straw is to crush the waste paper, and then add the straw powder and use biological materials and organic materials to scientifically mix and press directly. The water vapor is discharged without any pollution to the environment. At the same time, it uses waste paper and does not need to be treated by chemical methods. It is not only environmentally friendly, but also reduces the amount of paper, no exhaust gas and waste water, and no pollution to the environment. It has made new contributions to people getting along with nature. In addition, after it is discharged, because it is a paper cellulose article, it can be recycled and reused after being crushed. The worst processing method can also be used as coal fuel, which has recycling value. Moreover, even after the collection, there is no reuse of raw materials and fuel, as long as the environmental protection personnel can burn it cleanly. Therefore, the traditional fireworks that we are carrying out in the environmental protection field reduces paper consumption and is also the quality of paper. For the gypsum block, there is no new source of pollution. There is recycling value after it is set off, and someone will recycle it. It can't be exported for gypsum seat, and the materials for waste paper seat are the same as those for traditional export products. Can produce fireworks for export.

The paper used for the traditional firework launcher is more than 3,000 yuan / ton, while the waste paper and straw firework holders use less than 600 yuan / ton. The raw material cost is only less than one-third of that of traditional fireworks. Traditional fireworks launching tubes can only be done one by one, the process includes the reel machine pulling the tube, cutting, drying, and mud bottoming, and then, according to the number of fireworks in a single row, each tube is pierced with two holes, two by two Thread the leads, repeat each row in a row, and finally tie it with tape and place it under the sun to dry it for charging. The entire production process is mostly done manually, with low productivity and high labor intensity, which cannot meet the requirements of large-scale production. Need; and labor costs are huge. Our process is to put the crushed material in a blender and mix it. Theorem is to discharge the material. After pressing for 20 seconds and 30 minutes, the product can be produced. The time for loading and unloading is about one minute. If it is a small size Can be 4, 8, 12 out. In terms of cylinders, you can achieve 2400 cylinders at a time. It is conceivable that 400 cylinders will take nearly two hours on the assembly line (others are not counted), which increases labor productivity by at least 50 times. Of course, labor costs are also very low.

A large amount of glue is used to make the tube by the traditional process. After being cut and bound, it is dried in the sun freely. During the drying process, due to the different stress release, it is easy to deform and affect the launch efficiency of the fireworks. The products of this project have the same formula and the same stress, and together with the bottom form a whole composed of several gardens. Restrict each other, connect with each other, form a whole like a honeycomb, will not be deformed. Under the same explosive conditions, the launch height of this product is higher, and it also makes a beneficial contribution to the front companies to improve market competitiveness and reduce costs.

To sum up, 1. Use the waste paper and straw to scientifically dispose the bottom of the firework holder at one time; 2. After discarding, it can be automatically consumed in the nature, or re-made, or used as fuel, without generating new Pollution. 3. High degree of automation, continuous production greatly reduces labor costs. 4. The raw material cost and production cost are extremely low. 5. It can save a lot of space and flow cost of fireworks. Only need to produce effects, assembly workshop, saving more than 2/3 of the site. It is a win-win project.
