preparation example Construction

[0031] In an embodiment, the preparation method of smokeless mosquito-repellent incense comprises the following steps:

[0032] S1: After the sludge is dried at 106-110°C for 20-23h, under the protection of nitrogen or carbon dioxide, the temperature is raised to 500-600°C at a rate of 20-25°C / min, carbonized for 0.6-1h, and cooled to obtain Sludge carbon, after the sludge carbon is crushed through a 60-80 mesh sieve, sludge carbon powder is obtained;

[0033] S2: Take 140-200 parts of sludge carbon powder prepared in step S1, 6-8 parts of anthracite, 24-32 parts of binder, 4-6 parts of mica powder, and 400-500 parts of water, at a temperature of 60-70 °C, stirring at a speed of 200-300r / min for 1-2h to obtain a paste;

[0034] S3: Put the paste prepared in step S2 into a mold, compact and demould, and then dry at 45-55°C until the water content is ≤10%, to obtain a dry mosquito coil;

[0035] S4: Spray the mosquito-repellent incense potion evenly on the surface of the dried...

Embodiment 1

[0044] A preparation method for smokeless mosquito-repellent incense, comprising the following steps:

[0045] S1: After drying the sludge at 106°C for 23 hours, under the protection of nitrogen, raise the temperature to 500°C at a heating rate of 20°C / min, carbonize for 1 hour, obtain sludge carbon after cooling, and pulverize the sludge carbon Sludge carbon powder is obtained after passing through a 60-mesh sieve;

[0046] S2: Take 140 parts of sludge carbon powder, 6 parts of anthracite, 24 parts of binder, 4 parts of mica powder, and 400 parts of water prepared in step S1, and stir for 2 hours at a temperature of 60 °C and a speed of 200 r / min to prepare get a paste;

[0047] S3: Put the paste prepared in step S2 into a mold, compact and demould, and then dry at 45°C until the water content is 10%, to obtain a dry mosquito coil;

[0048] S4: Spray the mosquito-repellent incense potion evenly on the surface of the dried mosquito-repellent coil prepared in step S3 and dry ...

Embodiment 2

[0056] A preparation method for smokeless mosquito-repellent incense, comprising the following steps:

[0057] S1: After the sludge was dried at 110°C for 20 hours, under the protection of nitrogen or carbon dioxide, the temperature was raised to 600°C at a heating rate of 25°C / min, carbonized for 0.6h, and sludge carbon was obtained after cooling. Carbon pulverized through 80 mesh sieve to obtain sludge carbon powder;

[0058] S2: Take 200 parts of sludge carbon powder, 8 parts of anthracite, 32 parts of binder, 6 parts of mica powder, and 500 parts of water prepared in step S1, and stir for 1 hour at a temperature of 70 °C and a speed of 300 r / min to prepare get a paste;

[0059] S3: Put the paste prepared in step S2 into a mold, compact and demould, and then dry at 55°C until the moisture content is 8%, so as to obtain a dry mosquito coil;

[0060] S4: Spray the mosquito-repellent incense liquid evenly on the surface of the dried mosquito-repellent coil prepared in step S...

Abstract

The invention discloses a smokeless mosquito-repellent incense and belongs to the technical field of mosquito-repellent incense preparation.The smokeless mosquito-repellent incense is prepared from, by weight, 140-200 parts of sludge coal powder, 6-8 parts of anthracite, 24-32 parts of a binding agent, 4-6 parts of mica powder and 400-500 parts of water.According to the smokeless mosquito-repellent incense, sludge coal serves as an incendiary agent, inorganic matter in the sludge coal serves as a flame retardant, a novel approach is provided for resource utilization of sludge coal, a large amount of disafforestation in the mosquito-repellent incense industry is avoided at the same time, and thus environment protection is promoted.The smokeless mosquito-repellent incense is nontoxic, harmless and capable of meeting the requirement for the environment friendliness of the product; after the smokeless mosquito-repellent incense is burnt and absorbed by the human body, asthma, nerve positioning and cancer cannot be caused; the smokeless mosquito-repellent incense is smooth in appearance and free of cracks, the fracture resistance force reaches 431-463 g, the light time reaches 8.71-9.09 h, no smoke is generated in the combustion process, and end breakage and flameout can be avoided when the mosquito-repellent incense passes through an iron tooth disk.

Description

technical field [0001] The invention belongs to the technical field of mosquito-repellent incense preparation, and in particular relates to a preparation method of smokeless mosquito-repellent incense. Background technique [0002] Municipal sludge is the solid matter separated during the treatment of domestic sewage. These solid substances may already exist in sewage, such as suspended substances intercepted in various natural sedimentation tanks; they may also be transformed during sewage treatment, such as biological treatment and chemical treatment, from the original dissolved substances and colloids Biological flocs and suspended matter derived from material transformation. But generally speaking, the sludge of urban sewage treatment plants belongs to organic sludge, which is characterized by high organic matter content (60%-80%), fine particles (0.02-0.2mm), and low density (1.002-1.006g / cm 3 ), into a colloidal structure, accounting for about 0.3%-0.5% of the total ...
