环卫行业随着时代的变迁从98年到16年发生了巨大的变化： The sanitation industry has changed dramatically over the years from 1998 to 16. 第一代是玻璃钢材质的，这种材质敦厚结实方便了各种颜色图案的勾勒，最大的缺陷是，它的不可降解性导致它在废弃后对环境破坏比较大，且不容易清洗。 Is the first generation of glass fiber reinforced plastic material, the material is sturdy and convenient of all sorts of color design, the biggest flaw is that its cause it was abandoned after the degradability of environmental damage is larger, and not easy to clean. 二代产品是选用冷轧钢板焊接的钢结构果皮箱，它的优势在于造型多变，直接通过手工焊接便可成型，加大了其寿命。 Second generation product is made of cold-rolled steel sheet welding steel structure, chendu, its advantage lies in modelling changeable, can be directly through the manual welding forming, increase its life. 三代产品是不锈钢垃圾桶，最大的优点具有防腐蚀功能，还具有防火功能，坚固耐用。 The third generation product is stainless steel garbage can, the biggest advantage has anti-corrosive function, also have fire prevention function, strong and durable. 四代产品就是现代采用锌钢板作为原材料，镀锌可以延缓其生锈，再进入车间处理，一系列的工序，大大增加了垃圾桶使用的寿命。如今静电喷涂也取代了喷漆的老工艺，解决了大片脱落的问题。 The fourth generation product is the modern is made of zinc steel plate as raw material, galvanized can delay the rust, again into the processing workshop, a series of process, greatly increases the life span of the trash can use. Now electrostatic spraying also replaces the old process of spray painting, which solves the problem of large swabbed shedding. [钢木垃圾桶.jpg] [steel dustbin.]
