Manufacturing Method of Fuse Powder
Fuse Powder, chemically known as Sodium Lianodisulfite, is an important raw material for the production of chemicals. It has strong reducing properties and is widely used in textile, printing and dyeing, paper making, food and other industries. This article will introduce the manufacturing method of insurance powder in detail.
I. Raw material preparation
The main raw materials for manufacturing insurance powder are sodium hydroxide, sulfur powder and caustic soda. In order to ensure the quality of the product and the smoothness of the production process, it is necessary to choose high-quality raw materials.
II. Manufacturing process
1. Preparation of lye: Dissolve sodium hydroxide in water and prepare lye of a certain concentration, standby.
2. Melting sulfur: Heat the sulfur powder to the melted state, standby.
3. Reaction: Mix the lye solution with the melted sulfur and carry out the reaction to produce insurance powder.
4. Cooling and crystallization: Cool the reaction liquid to a certain temperature, so that the insurance powder crystallization precipitation.
5. Centrifugal Separation: Separate the crystallized insurance powder from the mother liquor by centrifuge.
6. Washing and drying: Wash the crystallized insurance powder with a small amount of water, and then dry it to a certain moisture content with drying equipment.
3. Precautions
1. Control the reaction temperature: the reaction temperature has a great influence on the yield and quality of the insurance powder, which needs to be strictly controlled.
2. Adjusting pH value: pH value needs to be adjusted during the reaction to ensure the production and stability of the insurance powder.
3. Preventing impurities from entering: impurities should be prevented from entering during the production process so as not to affect the product quality.
4. Yield and quality control
1. Yield: The yield is affected by many factors such as the quality of raw materials, reaction temperature, pH value, etc. It is necessary to determine the optimal process conditions through experiments in order to improve the yield.
2. Quality control: It is necessary to carry out quality inspection on the produced insurance powder, including purity, moisture content, pH value and other indexes, to ensure that the product quality meets the requirements.
V. Environmental protection and safety measures
1. Wastewater treatment: Wastewater produced in the production process needs to be treated to meet the environmental requirements.
2. Waste gas treatment: Collect and treat the waste gas generated in the production process to reduce the impact on the environment.
3. Safety protection: Strictly follow the safety operation regulations during the production process to ensure the safety of employees and equipment.
VI. Packaging and Storage
1. Packaging: Fuse powder is usually packaged in cardboard drums or plastic drums lined with plastic bags to ensure product quality.
2. Storage: Fuse powder should be stored in dry, cool and ventilated warehouse, avoiding direct sunlight and high temperature. During storage, it should be prevented from contacting with oxidizers and acids, so as not to cause fire or explosion.
Through the above manufacturing methods, we can get high quality Fuse Powder. In order to ensure the smooth production process and product quality, we need to strictly control each process condition and strengthen the quality management and environmental protection and safety measures in the production process. At the same time, reasonable packaging and storage is also an important part to ensure product quality and use safety.
