In the fast-paced world of construction, water-based release agents have become an indispensable tool for engineers and contractors to improve the performance of concrete surfaces. These chemical admixtures, also known as concrete release agents, play a vital role in controlling the set release of concrete to ensure its usability in pouring and finishing operations. With the latest advances in materials science, these products are now more effective than ever in meeting modern challenges, from sustainability to efficiency.
Water-based release agent, also known as water-based release agent, is developed from organic polymer materials, easily soluble in water, water, and then brushed directly onto the formwork to form a very slippery isolation film, which completely prevents direct contact between the concrete and the formwork and helps the air bubbles at the point of contact between the concrete and the formwork to spill out quickly when the concrete is being poured, so that the beams and columns do not have air holes, and is aesthetically pleasing. It does not affect the strength of concrete after use and has no corrosive effect on steel reinforcement, non-toxic, harmless, green products.
Water-based release agents for cast iron mold demoulding, need to be targeted to optimize the operation:
1 pretreatment before use: thoroughly clean the mold and remove rust, oil and residues, if necessary, with solvent wiping or sandblasting to ensure that the surface is flat.
2 film formation and penetration control cast iron pore more, it is recommended that several times thin coating or high solid content formula, to avoid the release agent penetrating the pores lead to release failure or residue. Spraying to maintain uniformity, the formation of a dense isolation film prevents liquid raw materials from penetrating the microporous adhesion.
3 Anti-corrosion and maintenance Priority is given to the use of water-based release agents containing anti-corrosion agents, and the molds are cleaned in time after demolding to avoid rust and corrosion caused by water retention.
Coated with antirust oil before long-term deactivation, double protection of the cast iron surface.
