Difference between water-based release agent and oil-based release agent

The main difference between water-based release agents and oil-based release agents is that the raw materials are definitely different, and the methods of use are also different. When using water-based release agents, mix them with water in a certain proportion before spraying. Water based release agents are easy to use, safe, and most importantly, environmentally friendly. Oil based release agents need to be mixed with solvents such as dichloromethane, petroleum ether, and 120 # gasoline before use. Compared to water-based release agents, they have higher costs, safety hazards, and are not environmentally friendly. Water based release agents have high requirements for the temperature of the mold, requiring the moisture inside to evaporate quickly. However, water-based release agents have a better operating environment, low odor, and minimal pollution. Oil based release agents evaporate quickly, so there is no need to raise the mold temperature to evaporate them. But there are more residues, which are relatively difficult to clean and have a strong odor.

水性脱模剂和油性脱模剂区别

Water based release agent, also known as water-based release agent, is developed from organic polymer materials and is easily soluble in water. After mixing with water, it is directly applied to the formwork to form a very smooth isolation film. This film can completely prevent direct contact between concrete and formwork and help the bubbles at the contact between concrete and formwork to quickly overflow during pouring, so that there will be no air holes in the beams and columns, which is aesthetically pleasing. After use, it does not affect the strength of concrete and has no corrosive effect on steel bars. Non toxic, harmless, and green products. Several points to note when using water-based release agents:

 

1. Before use, the membrane board should be cleaned thoroughly to remove cement residue and oil contamination.

2. The water-based release agent can be directly mixed with tap water and used without heating.

Traditional engine oil, also known as oil-based release agents, has high viscosity and consistency, making it difficult for bubbles to escape and causing air holes to appear on the surface after demolding. This seriously affects the adhesion between the subsequent surface plastering mortar and concrete base, and affects the quality of the project.
