Wax Emulsion Manufacturing Methods
I. Introduction
Wax emulsion is an important raw material for chemical production, which is widely used in many fields such as coatings, printing, textile and paper making. In this paper, a common wax emulsion manufacturing method will be introduced.
II. Materials and Equipment
1. Materials: paraffin wax, emulsifier, stabilizer, water and so on.
2. Equipment: emulsifying tank, stirrer, heater, cooler, etc.
3. Manufacturing steps
1. Dosing: add paraffin, emulsifier, stabilizer and water into the emulsifying tank according to a certain proportion.
2. Heating: Turn on the heater and heat the material in the emulsifying tank to a certain temperature to melt the paraffin.
3. Emulsification: Start the stirrer and mix the materials well to form emulsion.
4. Cooling: Cool the emulsified emulsion to room temperature.
5. Discharge: Discharge the produced wax emulsion from the emulsifying tank for packaging or storage.
4. Precautions
1. Strictly control the proportion of each component to ensure product quality.
2. During heating and cooling, constant temperature and rate should be maintained to avoid affecting product quality.
3. Stirring speed and time need to be adjusted according to the equipment and production requirements to ensure the emulsification effect.
4. Keep the equipment clean during the production process to prevent impurities from mixing into the product.
V. Quality test
1. Appearance: the wax emulsion produced should be milky white liquid, without impurity and odor.
2. Stability: Put the wax emulsion in constant temperature box and observe whether there are phenomena such as delamination and precipitation.
3. Particle size distribution: Detect the particle size distribution of the particles in the wax emulsion by laser particle size meter to evaluate the product performance.
VI. Packing and storage
1. Packing: according to the customer's demand, use appropriate packing materials for packing.
2. Storage: Store the packed wax emulsion in a cool, dry and ventilated warehouse, avoiding direct sunlight and high temperature environment.
VII. Waste disposal
Waste generated in the production process should be properly disposed of in accordance with environmental protection requirements to avoid pollution to the environment.
VIII. Safe production
1. Operators should be professionally trained and familiar with the production process and equipment operating procedures to ensure the safety of the production process.
2. The production site should be equipped with corresponding fire-fighting equipment and first-aid medicines to cope with emergencies.
3. Regularly check the operation of the equipment to ensure the normal operation of the equipment and prevent the occurrence of safety accidents.
9. Summary
This paper introduces a common wax emulsion manufacturing method, including the steps of batching, heating, emulsifying, cooling and discharging. In the production process, the proportion of each component, temperature and stirring speed and other parameters should be strictly controlled to ensure product quality. Meanwhile, attention should also be paid to issues such as safe production and waste disposal to ensure the smooth progress of the production process.
