Tips for the Safe Production of Water - based Adhesives
Hits: 652 img
Formulate production plans and strengthen workshop management; clarify employees' responsibilities and ensure division of labor and cooperation.
Weigh the additives by category and place them separately to ensure convenient access. Timely clean and organize the workshop.
Equip high - pressure water guns to clean the reaction kettle in a timely manner. Equip post - elimination tanks and storage tanks to achieve semi - continuous production.
During the heat - preservation stage, prepare the pre - emulsion for the next batch. The specific methods are as follows: for continuous production, add all the pre - emulsified raw materials and stir thoroughly; for semi - continuous production, only add water, emulsifier and the main monomer and stir evenly. The separately placed additives are added when the production starts.
Improve the ventilation conditions in the workshop.
Eliminate the phenomena of running, emitting, dripping and leaking.
Improve the condensation efficiency of the condenser.
Appropriately increase the reaction temperature during the heat - preservation stage to make the reaction complete. Operate strictly in accordance with the post - elimination process.
During the heat - preservation process, release 10 - 20 kilograms of glue from the bottom of the kettle and pour it back into the reaction kettle. This can be repeated as necessary.
After cooling to 50 °C, open the lid of the reaction tank intermittently. If necessary, evacuate to remove residual monomers.
For the ammonia volatilization caused by high temperature, the method of adjusting the pH value by mixing monoethanolamine and ammonia water at a ratio of 1:1 can be adopted. The AMP - 95 multifunctional additive may cause filtration difficulties, so it is not recommended.
If it is caused by the excessive residual alcohol ethers in the water - soluble resin, the resin should be replaced with a new one.
