旧家具回收可利用率高

  据了解,通过拆解后的不同类别的家具废料,在回收市场会分别被相应的摊位回收,并送往各自需要的渠道,真正必须焚烧或者填埋的非常少,甚至不到1%。
  回收市场作为一个平台,除了完成拆解工作外,还会将同种类的废旧材料打包,比如金属材料会通过金属剪切机统一剪成相应的尺寸,再由金属压块机压成同样大小的块状,便于在送往钢厂的过程中搬运和称重;海绵、布料也会分别包成一袋一袋的;木质材料在去除五金配件后,也会将大小材质差不多的板材放到一起打包。
  这其中,被运走的木质材料分为两种,实木材料就直接送往一些家具厂,大件的实木可以直接再利用做成小件的家具,具体只需要去除一下表面的油漆即可;非实木多为人工板材,包括胶合板、刨花、纤维板等。据中国木材节约发展中心总工程师陶以明介绍,人造板因为本身就是由胶粘剂粘成的,其中还含有甲醛类的物质,处理起来就相对麻烦。需要先粉碎成颗粒,将原来加进去的胶取出来,所以处理的成本会高一些,但打碎后一样可以再做成新的人造板,处理过程如果控制严格也不会造成污染。
  至于危险废料,陶以明表示,木制品家具里的危废并不多,比如有些人造木材里面加防腐剂、防虫剂等,这些物质里一般会含有重金属,所以处理时如果直接燃烧,必然会污染空气,必须粉碎后再次利用,以减少对环境的污染。另外,家具表面的油漆里面可能会有苯、甲醛等,也需要做同样的处理。Learned, after dismantling the furniture of different categories of waste, and the market will be the corresponding respectively in recycling stall recovery, and sent to the respective needs of channels, really have to burn or bury very few, even less than 1%.
Recycling market as a platform, in addition to the complete dismantling work, also will be the same kind of waste packaging materials, such as metal materials will be through the metal shearing machine cut into appropriate size, again by metal press pressure into the same size of the block, facilitate to the steel mill in the process of handling and weighing; Sponge, cloth, also can respectively pack into a bag of a bag; Woodiness material after removal of hardware accessories, can also with packaging material similar to the size of the plate together.
In that shipped the woodiness material is divided into two kinds, real wood material is directly sent to some of the furniture factory, bulk solid wood can direct reuse of small furniture, specific you just need to get rid of the surface paint. The solid wood for artificial plate, including plywood, wood shavings, fiberboard, etc. According to the development of Chinese timber saving center chief engineer of the tao to Ming, man-made board because itself is made up of a adhesive glue, which also contains formaldehyde class material, is relatively complicated to handle. Need to smash into particles, the original add glue out, so the processing cost will be higher, but after the break can make new man-made board, strict process if control don't cause pollution.
As for hazardous waste, tao yiming, said the waste in the wood furniture is not much, such as some artificial wood preservatives, pest control, etc., these substances generally contain heavy metals, so if direct combustion, when processing will pollute the air, must use again, after crushing in order to reduce pollution to the environment. In addition, the paint on the surface of the furniture inside may have such as benzene, formaldehyde, also need to do the same.
