护坡模具发展给社会带去了积极的效应
对于市政环境的建设来说,护坡模具的使用占据了很大的一部分,这种水泥制品的使用促使了道路修建水泥预制件的使用,因为模具的制作包含了很多的过程,每一个过程都需要人员的运作,能够促进当地经济的快速发展,模具的使用也促使整个工程降低了劳动量,使得整个生产过程得到了有利的改善,给社会带去了积极的效应。
For the construction of municipal environment, the use of slope protection moulds occupies a large part. The use of this kind of cement products promotes the use of cement prefabricated parts in road construction, because the production of moulds involves many processes, each process requires the operation of personnel, which can promote the rapid development of local economy and the use of moulds. It also reduces the workload of the whole project, improves the whole production process and brings positive effects to the society.
护坡模具在定型之前都存在内应力,如果在模具成型的过程中因操作不当而使内应力过高,则会导致产品的变形或者是出现银纹或破裂。那么,导致模具内应力过高的因素有哪些呢?填充过度或者是厚度不够导致收缩不均;因压力过大而造成脱模困难;结晶性塑料结晶性不充分等,这些都会导致内应力过高。
Internal stress exists in slope protection die before finalization. If the internal stress is too high due to improper operation in the process of mould forming, it will lead to deformation or craze or fracture of the product. Then, what factors lead to excessive stress in the die? Overfilling or insufficient thickness leads to uneven shrinkage; excessive pressure leads to difficult demoulding; inadequate crystallinity of crystalline plastics, etc., which will lead to excessive internal stress.
对于护坡模具的使用,人们常常陷入误区。使用过后不能进行细心的保管,随意堆放在无人看管的室外场地上,这样的使用误区会导致模具弯曲,下次使用时六角护坡模具无法恢复原有的形状、尺寸与精度。在使用模具加工水泥制品时,倒入模具型腔的水泥制品加工材料温度过高或者温度过低。此类型的使用误区会使护坡模具受到高温影响融化或受到低温影响变脆,失去应有的精度和强度。
For the use of slope protection moulds, people often fall into a misunderstanding. After use, it can't be carefully kept and stacked on the unattended outdoor field. Such misuse will lead to the bending of the die. The hexagonal slope protection die can't restore its original shape, size and accuracy when used next time. When using the mould to process cement products, the temperature of the processing material of the cement products poured into the mould cavity is too high or too low. This kind of misuse will cause the slope protection die to melt under the influence of high temperature or become brittle under the influence of low temperature, thus losing its due precision and strength.
