一般来说，造成塑料护栏模具脱模困难主要有一下几点因素，1、使用混凝土配料配比不当。2、浇筑前所涂抹的脱模剂不当。3、蒸养过程时间过长过短温度过高过低都会影响到成型的水泥制品外观以及脱模效果。
Generally speaking, there are several main factors that make it difficult to demould the plastic guardrail mould. 1. The improper proportion of concrete ingredients. 2. The mold release agent applied before pouring is improper. 3. The appearance and demoulding effect of the formed cement products will be affected by too long steam curing time, too short steam curing time and too high or too low temperature.
脱模剂的使用不当，脱模剂的种类有很多种类，主要有硅系脱模剂、氟系脱模剂、蜡( 油) 系脱模剂、表面活性剂系脱模剂、其他类型脱模剂、内加型脱模剂以上六种，洞口思多园模具制造厂年来销售的经验下，大多数的客户都是使用柴油为脱模剂，在价格上也较为便宜，效果也较为客观，对塑料护栏模具的损害不大。
There are many kinds of release agents, such as silicon release agent, fluorine release agent, wax (oil) release agent, surfactant release agent, other types of release agent, and internal release agent. Most of the customers are satisfied with the sales experience of Dongkou Siduoyuan Mould Factory in recent years. Diesel oil is used as demoulding agent, which is cheaper in price and more objective in effect, and has little damage to the plastic fence mould.
在模具内部使用好脱模剂后，在将混凝土倒入混凝土圆弧型路牙石模具中通过使用震动的方式，将水泥模具内的空气进行排放，让浇筑成型的水泥预制件外观更为美观使用寿命更为长久。
After using the release agent in the mould, the air in the cement mould is discharged by pouring the concrete into the concrete circular-arc dental stone mould by vibration, which makes the appearance of the cast-in cement prefabricated parts more beautiful and has a longer service life.
