| 1. 聚丙烯和ABS工程塑料的水泥模具，在浇筑预制前一定要在塑料模具内壁涂抹一定厚度的脱模剂，脱模剂一般可以是费机油、洗 涤液或其他一些有机溶剂，在根据水泥预制件的形状配合相关脱模机械设备来进行脱模，最为方便，而且水泥预制件脱模完成整体 质量更为优质，不太容易会造成其缺角、表面裂纹等次品产生。相关的配套机械设备，比如如果是普通的水泥平石、盖板等，水泥 模具及预制件都是平底结构，那么可以使用振动台来调整震动频率，非常容易。又或者一些水泥栏杆的预制脱模，可以使用离心机 转动脱模，道理其实跟振动台差不多，只是用离心机可以更好的保障圆柱体形状的水泥预制件质量更佳。 1. Before pouring the cement mould of polypropylene and ABS engineering plastics, a certain thickness of release agent must be applied on the inner wall of the plastic mould. The release agent can generally be used as engine oil, washing liquid or some other organic solvents. It is most convenient to release the mould according to the shape of the cement prefabricated parts and the relevant release machinery and equipment. Moreover, the overall quality of the demoulding of cement prefabricated parts is better, and it is not easy to cause defective products such as angle gap and surface crack. Relevant supporting machinery and equipment, such as ordinary cement flagstone, cover plate, etc., cement mold and prefabricated parts are flat bottom structures, so it is very easy to use the shaking table to adjust the vibration frequency. Or the prefabricated demoulding of some cement railings can be done by rotating centrifuge, which is similar to the shaking table, but the centrifuge can better guarantee the quality of cement prefabricated parts with cylindrical shape. 2.钢铁材质的水泥模具，一般采用钢铁材质的水泥模具尺寸都较大，所以在生产水泥钢模具时候会以锁扣可拆卸的设计来生产模具 ，在预制前也可以在水泥钢模具内涂抹一些脱模剂，然后直接拆卸锁扣、螺丝、螺母等固定配件即可完美脱模。 2. Cement moulds made of iron and steel are generally larger in size, so in the production of cement steel moulds, the design of detachable locking will be used to produce moulds. Before prefabrication, some release agents can also be applied to the cement steel moulds, and then the fixed parts such as locking, screw and nut can be directly removed. Perfect demoulding can be achieved. 3.硅胶类的水泥模具，此类材质的模具脱模最为麻烦，一般尺寸较小，比较常见的有预制小花盆的水泥硅胶模具，预制完成一般直 接用手抠就可以，但是如果没有控制好硅胶模具的原料气泡，那么可能在水泥制品表面也会产生相对数量的小气泡，所以实际是比 较难控制且重复使用次数较低的一种水泥模具材质。 3. Silica gel type of cement mold, this kind of material's mold demoulding is the most troublesome, the general size is small, the more common cement silica gel mold with prefabricated small flowerpot, prefabricated completion can generally be directly hand-picked, but if the raw material bubbles of the silica gel mold are not well controlled, it may also produce on the surface of cement products. Relative number of small bubbles, so it is actually a relatively difficult to control and reuse of a low number of cement mold materials. |
