在钢模上浇注混凝土,脱模时的吸附力高达55～400公斤/米~2。在外墙板“反打”新工艺中,底模具有线型、纹理质感,表面积增大,其吸附力也随之增大,为此在选择适当衬模材料的同时,还应注意脱模剂的选择。脱模剂在脱模后不得残留在板面,以免影响装饰材料粘结效果;涂刷脱模剂时不得聚积 The concrete is cast on the steel mold and the adsorption force during demoulding is as high as 55-400 kg/m2. In the new technology of exterior wall panel “backhand”, the bottom mold has a wired type, texture texture, and the surface area increases, and its adsorption force also increases. Therefore, in selecting the appropriate liner material, attention should also be paid to the choice of release agent. . The release agent must not remain on the board surface after demoulding, so as not to affect the bonding effect of the decorative materials; the release agent must not accumulate when brushing the mold release agent.
