[0002] Precast concrete parts are building components made in factories with concrete as the basic material. Common ones include precast concrete floor slabs, concrete box beams for bridges, precast concrete roof trusses for industrial plants, culvert frames and precast concrete piles for foundation treatment. In order to ensure the processing quality of precast parts, a release agent is sprayed on the inner wall of the precast mold before the precast concrete parts are molded to play a role in lubrication, isolation and anti-sticking. The release agent can make the concrete demoulding smooth after high temperature, protect the precast concrete parts while avoiding mold damage, reduce the workload of mold cleaning, and improve the quality of precast concrete parts.
