高速公路铁路里程碑模具
The prefabricated milestone mold is often used on both sides of the highwayBspore B����, so as to play a warning role. Therefore, when making these milestones, the corresponding prefabricated milestone mold can be used. When using these highway milestone molds, what should be paid attention to? First of all, because the dimensions of these used milestones are not very large, so in the selection of materials Because the price of plastic is relatively cheap, the cost will be reduced. Moreover, because the plastic does not react with water and is not easy to be oxidized, it can ensure that in the process of use, it will not cause the loss of mold To ensure that the service life of the products is greatly increased, it is actually necessary to pay attention to one point in the process of use, because the raw materials commonly used in the production of these prefabricated milestone molds are cement, concrete and other things, so these materials are liquid. In the process of filling, there may be bubbles in, so it is in operation In the process of making, it needs to be placed in a vibration environment for oper
