Abstract

This invention discloses a coiled mosquito-repellent paper incense and its production method. The paper incense is made by coiling two flat elongated strips. The cross section of the strip is approximately rectangle and the long edge is in the width direction. The paper incense comprises base material and mosquito-repellent solution sprayed on the base material. The base material is composed of 450-700 parts plant fiber, 150-450 parts wood charcoal powder and/or bamboo charcoal powder, 100-200 parts light calcium carbonate and/or kaolin by weight. The mosquito-repellent incense has good smoldering capacity and impurities have small impact onits combustion time and intensity. The mosquito-repellent incense has no naked fire and produces little smoke. Besides above advantages, since the mosquito-repellent incense is not subject to break, the production efficiency is increased highly and the damage rate during transportation is lowered. Wood charcoal or bamboo charcoal has porous structure, so the mosquito-repellent incense also has bactericidal effect.

Description

 Disc type paper mosquito coil and production process thereof

 The invention relates to a disc paper mosquito coil and a special production process for the mosquito coil.

Background technique:

 Traditional black mosquito-repellent incense, green mosquito-repellent incense, red mosquito-repellent incense and other raw materials are broken into powder by burning wood powder with trees and trees, and extruded with a binder. Such traditional mosquito coils have poor combustion properties and are produced. The mosquito-repellent material has poor bonding strength and low strength, and the finished product rate is low, and the finished product is easy to be broken. The slight incorporation of impurities in the main raw material toner affects the ignition time and the strength of the mosquito-repellent incense, and the mosquito smoke burns after the smoke is large. Stimulating the human body has an adverse effect on people's health. The absorption of mosquito repellent drugs is not good. Traditional mosquito coils use wood raw materials in a large amount, which makes the already insufficient wood resources more tense.

 The mosquito-repellent incense film, which is now popular, uses electric heating to volatilize the insect repellent in the tablet. However, this mosquito-repellent tablet has a large amount of volatilization in the early stage of heating, although it is also marked as sustainable.

8 --- 10 hours, but the concentration of volatilization is different before and after. When it is just powered on, the amount of volatilization is large, and the effect of repellent is good. After 6 hours of electric heating, the effect of repellent is obviously reduced because the liquid has basically evaporated. Therefore, the effect of mosquito repellent on the mosquito repellent during the whole mosquito repellent period varies greatly. Summary of the invention:

 In view of the deficiencies of the prior art, the present invention provides a disk with good combustion performance, small influence of impurities on ignition time and strength, long burning time, no flameout, small smoke generation, and uniform mosquito repellent effect in the whole effective mosquito repellent time period. Mosquito-repellent incense, this kind of mosquito-repellent incense, high strength, good toughness, high production yield, low breakage rate of handling, not easy to break, uniform release of drugs, mildew resistance, and sterilization function.

 Each strip of musk has a width of 2 mm - 6.5 mm, a thickness of 2 mm - 5 mm, and a logo or pattern or text or color on the disc surface; the two coils are wound from the center and are coiled in a nearly rectangular shape. The ends of the center are each provided with an approximately rectangular receptacle.

 The plant fiber in the present invention can be selected from paper fibers, especially waste paper raw materials. Since the raw materials can be selected from waste paper, it is also called paper mosquito coil.

 The production process of the mosquito coil of the present invention comprises the following steps:

 (1) removing plastic impurities in waste paper, especially foam plastics;

 (2), waste paper is added to the hydraulic pulper, and water is broken into plant fibers;

 (3) adding water to the slurry, washing, screening with a sieve machine to remove impurities and fiber bundles;

(4), the slurry is added to the slurry tank, concentrated, and the concentration of the slurry is 5-8%;

 (5), beat with a disc machine, control the degree of beating 28-35 ° SR;

 (6), ingredients in the matching tank: 450 parts --- 700 parts of plant fiber

 150 ^ ^-- 450 parts of charcoal powder and / or bamboo charcoal powder, 100 parts --- 200 parts of light calcium carbonate and / or kaolin, appropriate amount of enhancer, neutral glue, combustion improver;

 (7), using a paper machine to form a wet paper tire;

The process of the invention uses waste paper as a raw material, has low cost and is easy to obtain, and at the same time avoids the use of wood in a large amount and destroys the ecological environment. It is very important to remove the plastic impurities in the waste paper and the waste paper slurry to remove impurities. In order to remove various rubber fillers in the waste paper slurry and remove impurities such as plastic sheets, if mixed in the slurry, it will affect the burning time of the finished product. And causing flameout; of course, the choice of using pure wood to directly make plant fibers, can also save the process of impurities.

 Beating with a disc grinder, so that the beating degree of the slurry is 28-35° SR is high in a certain range, and the paper forming strength is good. In order to obtain a suitable beating degree, the pulp concentration of the grinding disc machine is crucial, which is 5-8%. .
