Abstract
The invention discloses a sorting method for PVC waste materials. The sorting method comprises the following steps: (1) determining the color categories of same or similar PVC waste materials; (2) classifying the colors with large differences of the PVC waste materials into a variety of color systems, and preparing a color system comparison strip; (3) integrating the waste materials of the same color system, crushing and grinding into powder; and (4) adjusting charging according to physicochemical properties of the PVC waste materials of the color system, and carrying out the production of the PVC profile again to realize recycling of the waste materials. According the invention, the PVC waste materials are sorted according to the color systems, the operation is intuitive, a common worker can make the color system comparison strip, so as to rapidly sort the PV waste materials, the work efficiency is improved, the work amount of technical workers is reduced, raw material resources are saved, the performances of a recycled product are guaranteed, the production cost of the PVC profile is reduced, and the pollution of the PVC waste materials to the environment is overcome.
Description
Technical field
The present invention relates to PVC waste recovery technical field, be specifically related to a kind of sorting technique of PVC waste material.
Background technology
In the extrusion of PVC section bar, because a variety of causes (as quality debugging, troubleshooting, normal start-stop car etc.) there will be a large amount of waste materials; Meanwhile, in door and window production process, also can produce a large amount of leftover bits.If these waste materials do not reclaim, can affect the economic benefit of enterprise; As reclaim improperly, can affect section quality.Therefore, PVC waste recovery is an important very important job.The PVC waste material that different extrusions produce, not only processing characteristics and serviceability have very big difference, also can produce aberration in various degree simultaneously, and therefore, the classification of PVC waste material is reclaimed and is seemed particularly important.
The classification of traditional PVC waste material is very complicated, that the waste material of PVC section bar of the same race is classified, then reclaim several times, recovery process complexity, for the comparatively similar also differentiated treatment of PVC waste material of properties, organic efficiency is low, or the PVC waste material directly producing throws away, and causes a large amount of wastes and environmental pollution.
Summary of the invention
The object of the invention is to overcome and recycled the PVC waste material difficult technical problem of classifying in the past, a kind of sorting technique of PVC waste material is provided.
The present invention is achieved through the following technical solutions: a kind of sorting technique of PVC waste material, comprises the following steps:
(1) determine identical, the color category of close PVC waste wood;
(2) color of PVC waste wood larger difference is divided into multiple colour system, and makes colour system comparison bar;
(3) waste material of same colour system is integrated, fragmentation, breaks into powder;
(4) according to the physicochemical property of this colour system PVC waste wood, adjust and feed in raw material, re-start the production of PVC section bar, realize being recycled of waste material.
Due to the different PVC section bars different color distortion of bad student in process of production, the physico-chemical property that color is close is similar, so first will determine and use how many kinds of colour system that waste material is classified, is generally no more than five kinds of colour systems.After dividing good class, be made into colour system contrast bar, use colour system contrast bar, being placed on PVC waste material place compares, can determine the PVC waste material which kind of colour system this PVC waste material is, convenient and swift, common staff also can distinguish fast, and good classification effect, be difficult for makeing mistakes, PVC waste material is broken into powder, reach after powder, the convenient physicochemical characteristic of surveying PVC waste material, determine that the PVC waste wood powder of different physicochemical characteristics can manufacture the type of PVC section bar again, according to the physicochemical property of this colour system PVC waste wood, adjust reinforced, detection reaches after use standard, dropped into PVC profile-forming machine and carried out the production of PVC section bar, realize being recycled of waste material.
Further, in described step (2), colour system classification comprises coffee colour system, yellow system, green system, white color system, grey colour system.These five kinds of colour systems, are the classification existing in the situation of most species, any PVC waste material all within these five kinds of colour systems.
Further, in described step (3), breaking into powder is to be undertaken by flour mill.The apparatus that PVC can be reached to waste material is incessantly a kind of, and preferred powder grinding machine is as the apparatus that PVC waste material is broken into powder here.
Further, described powder diameter is 600 ~ 800 orders.600 ~ 800 object powder diameters are optimum states of surveying PVC waste material physico-chemical property, therefore select to be reached 600 ~ 800 orders.
Further, in described step (4), adjust in reinforced process, feed in raw material and comprise stone flour, plasticizer, stabilizing agent, flexibilizer and PVC virgin material.According to the physico-chemical property that detects PVC waste material, feed in raw material and adjust its physico-chemical property, generally add stone flour, plasticizer, stabilizing agent, flexibilizer and PVC virgin material are adjusted the physico-chemical property of PVC waste material, and how many ratios are determined by practical operation.
Further, the particle diameter of described stone flour is 200 ~ 300 orders.The particle diameter of described stone flour, using 200 ~ 300 orders as preferably, can reach same texts stone flour particle diameter here, also can meet the demands.
Further, described stabilizing agent is zinc stearate.Here preferably zinc stearate, as stabilizing agent, adds PVC waste material powder, the stability of Reinforced PVC waste material powder, and the stabilizing agent that can reach effect of the same race all can be selected.
Further, described flexibilizer is ACR.Here preferably ACR, as stabilizing agent, adds PVC waste material powder, the pliability of Reinforced PVC waste material powder, and the flexibilizer that can reach toughening effect of the same race all can be selected.
Further, described plasticizer is epoxyoleic acid butyl ester.Here preferably epoxyoleic acid butyl ester, as stabilizing agent, adds PVC waste material powder, the plasticity of Reinforced PVC waste material powder, and the plasticizer that can reach effect of the same race all can be selected.
The present invention compared with prior art, the advantage having and beneficial effect are: the present invention is by colour system to the processing of classifying of PVC waste material, and comparatively directly perceived, common work employee just can complete, and become colour system contrast bar according to colour system classification system, can fast PVC garbage area be separated, improve operating efficiency, reduce technical staff's workload, raw material resources are saved, ensure to reclaim the performance of product, reduced the production cost of PVC section bar simultaneously, overcome the pollution of PVC waste material to environment.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this, without departing from the idea case in the present invention described above, according to ordinary skill knowledge and customary means, make various replacements and change, all should comprise within the scope of the invention.
Embodiment:
The present embodiment discloses a kind of sorting technique of PVC waste material, comprises the following steps:
