| 多数模板材料都需要采用脱模剂，以防止混凝土与模板表面粘结。如果拆模时模板面与混凝土相互粘 结，模板使用一二次就可能损坏。如果混凝土强度比模板弱，部分混凝土表层便会剥落并粘附在模板上； 如果混凝土强度比模板强，部分模板面层有可能被拉脱并粘在混凝土上。 Most formwork materials need to use demoulding agent to prevent concrete from bonding to the surface of the formwork. If the formwork surface is bonded to the concrete when the formwork is removed, the formwork may be damaged once or twice. If the strength of concrete is weaker than that of formwork, part of the surface of concrete will peel off and adhere to the formwork; if the strength of concrete is stronger than that of formwork, part of the surface of formwork may be pulled off and adhered to concrete. 采用优质脱模剂，可以防止上述 两种情况的发生。脱模剂还能封闭吸水性模板材料的表面，从而延长模板的使用寿命。一般模板油和脱模 剂都能防止粘结，但使用适当品种的脱模剂，更有助于保护模板。正确选用优质脱模剂，可以减少混凝土 的色差、污染、气孔以及提高混凝土表面的耐久性。优质脱模剂在规定的覆盖厚度内容易涂敷均匀，并且有 利于增加模板重复使用的次数。 The use of high quality release agent can prevent the occurrence of the above two situations. The release agent can also seal the surface of the absorbent template material, thus prolonging the service life of the template. Generally, template oils and release agents can prevent bonding, but the use of appropriate types of release agents is more conducive to the protection of templates. Correct selection of high quality demoulding agent can reduce the color difference, pollution, pore and improve the durability of concrete surface. The high quality release agent is easy to be uniformly coated in the prescribed coverage thickness, and is conducive to increasing the number of template reuse. |
