Manufacturing Methods of Emulsifiers
I. Introduction
Emulsifiers play an important role in the production of chemicals, they can improve the stability and performance of products. In this paper, we will introduce the manufacturing methods of emulsifiers, including the aspects of raw material selection, production process and equipment requirements.
2. Selection of raw materials
The manufacture of emulsifiers requires the selection of suitable raw materials, which generally include the following:
1. Surfactants: Commonly used surfactants are anionic, cationic, nonionic and amphoteric. When choosing surfactants, it is necessary to consider its hydrophilic and lipophilic balance value (HLB value), foam, stability and other factors.
2. Fats and oils: Fats and oils can be used as oily raw materials for emulsifiers, commonly used vegetable oils, animal oils and synthetic fats and oils.
3. Water: water is one of the main ingredients in emulsifier, need to choose pure water quality.
3. Production process
There are various manufacturing processes for emulsifiers, and the following is a common production process:
1. Dosing: add raw materials such as surfactant, grease and water into the dosing tank according to the formula ratio, and mix well.
2. Emulsification: The materials in the dosing tank are pumped into the emulsifier for high-speed mixing and shearing to fully emulsify the materials. The type and parameters of emulsifier need to be selected according to the product requirements.
3. Blending: Pump the emulsified material into the blending tank and add other additives for blending to make the product performance more stable.
4. Homogenization: The homogenized material enters into the homogenizer for high-pressure homogenization to make the particle size distribution of the product more uniform.
5. Cooling: The homogenized material enters into the cooler for cooling to make it reach the specified temperature.
6. Discharge: The cooled material is discharged through discharge pump for packaging or storage.
4. Equipment Requirements
The manufacture of emulsifier requires the use of various equipments, and the following are the requirements for the main equipments:
1. Dosing Tank: It needs to have enough capacity and stirring device to ensure the materials are stirred evenly.
2. Emulsifier: It needs to have high speed mixing and shearing function to fully emulsify the material. Meanwhile, it should be easy to clean and maintain.
3. Blending Tank: It needs to have heating and cooling functions to ensure that the materials are blended within the specified temperature range. Homogenizer: It needs to have the function of high pressure homogenization, which can ensure that the particle size of the product is uniformly distributed. At the same time, it needs to have the characteristics of easy cleaning and maintenance.
5. Cooler: It needs to have efficient cooling function, which can ensure that the material is cooled to the specified temperature within the specified time.
5. Quality control
In order to ensure the product quality of emulsifier, it is necessary to establish a perfect quality control system. The following are the main requirements for quality control:
1. Quality control of raw materials: it is necessary to strictly control the quality of raw materials to ensure that the raw materials meet the specified requirements.
2. Quality control of production process: It is necessary to carry out comprehensive monitoring of the production process to ensure that the parameters of the production process and the performance of the product meet the specified requirements.
3. Quality control of finished products: It is necessary to carry out quality inspection and testing of finished products to ensure that the products meet the specified quality standards and customer requirements.
VI. Environmental protection
The manufacturing process of emulsifier will produce certain pollutants such as waste water, waste gas and waste residue, which need to pay attention to environmental protection. The following are the main requirements for environmental protection:
1. Wastewater treatment: It is necessary to treat the production of wastewater to ensure that the wastewater meets the national emission standards.
2. Waste gas treatment: It is necessary to treat the production waste gas to reduce air pollution.
3. Waste residue treatment: it is necessary to carry out reasonable utilization or safe treatment of production waste residue to avoid harming the environment.
VII.CONCLUSION
The manufacturing method of emulsifier involves many aspects, including raw material selection, production process, equipment requirements, quality control and environmental protection. Only by considering these factors comprehensively can high quality, stable and reliable emulsifier products be manufactured.
