Abstract
The invention discloses a process for recycling waste toothpaste aluminum-plastic composite packaging material. The process is characterized by comprising the following steps: (1) treating crushed materials; (2) separating aluminum and plastics; (3) granulating plastics and producing a finished product; and (4) producing aluminum-silver powder. In the process, the toothpaste aluminum-plastic composite packaging material is used as a raw material, and reagents are all non-toxic, therefore the high-quality polyethylene plastic product and aluminum powder can be produced; and the whole process for recycling the waste toothpaste aluminum-plastic composite packaging material does not generate any industrial pollution. The process is simple to operate and environmentally friendly and has the characteristics of low cost, high benefit, no toxicity, low process condition requirement and the like.
Description
Technical field
The present invention relates to a kind of technique of recycling as raw material take waste toothpaste aluminium plastic composite packaging plastics.
Background technology
In recent years along with China's expanding economy, all kinds of aluminum-plastic packagedly rise rapidly.The annual use amount of China is more than 8,000,000 tons according to statistics, and with annual 20% speed increase.China has 70% packing articles to be dropped after use every year, and the environmental pollution that aluminum-plastic packaged discarded object brings is only second to water pollutes, the position of being number four.According to the authoritative department data: 2008, the plastic package material total amount of China production reached 1690.8 ten thousand tons, and with annual 15% speed increase.For solving the wasting of resources and problem of environmental pollution, a lot of developed countries are all " changing rejected material to useful resource " emphasis as national economic development in the world.The recent statistics data that Britain's environment, food and Rural Affairs section and Britain environment administration announce show: 2008, the container package that Britain uses had 2/3 to accomplish recycling.In the same year, Britain enterprise has reclaimed the packaging waste more than 7,000,000 tons, and wherein recycling reaches 6,600,000 tons.Increasing of commodity also brought increasing of packaging waste, wherein much packs manufacturer and adopted aluminium plastic composite packaging for the shelf-life of improving product, particularly some high-grade goods such as food, medicine, cosmetics.Aluminium plastic composite packaging refers to a kind of aluminium the pool and the high-grade packaging material of plastics by being combined with each other after processing, and some developed countries are universal already in the west.
China all produces the aluminum-plastic packaged discarded object of millions of tons every year at present.Because plastic-aluminum combined refuse can not be directly produced regeneration and granulation as plastic wastes, also can't work as aluminium waste recovery smelting, so many salvage collections department rejects this type of discarded object.The processing of have to burning of a lot of places had so not only caused serious environmental pollution but also had wasted valuable social resources.In these aluminum-plastic packaged discarded objects, plastic material is main component.Only have these Plastics Packaging Wastes are recycled or regeneration, could solve the pollution problem that these plastic refuses bring to surrounding environment.The recoverable rate of plastics has very high economic worth, and regenerated plastics are than the energy consumption low 30% of recycled writing paper.So the regeneration of aluminum-plastic packaged thing discarded object will promote the packing material innovation and turn to " resource regeneration " from " green revolution ".Make packaging waste from burning, the unicity such as landfill are processed and are turned to the resource recycling.
Summary of the invention
The purpose of this invention is to provide in the aluminum-plastic packaged MAT'L recycling process of a kind of whole waste toothpaste and do not produce any industrial pollution; Aluminium, mould separate easily, recovery rate is fast, processing cost is low, store transport again raw product easily toothpaste aluminum-plastic composite packaging recycle technique.
The technical solution used in the present invention is: a kind of process for recycling waste toothpaste aluminum-plastic composite packaging is characterized in that: comprise the steps:
Described step
The concrete technology parameter that plastic granulating and finished product are produced modified particles production is as follows:
Technological temperature (℃) 1 district's 2 district's 3 district's four district's heads
175±5 180±5 185±5 190±5 195±5
Melt pressure: melt pressure≤7.0Mpa.
the present invention is in a large amount of aluminum-plastic separation production practices, characteristics according to the aluminum-plastic separation reaction, the useless aluminum-plastic packaged material of toothpaste is being carried out sorting, clean, broken, after drying waits treatment step, adopt the separating reaction container, aluminum-plastic separation soaks bleeding agent, screening installations etc. carry out aluminium to aluminum-plastic packaged broken material, the separation of moulding material, aluminium and plastics after separation are dried separately, aluminium is directly produced aluminium silver powder with the production of aluminum powder device, after the plastics clean dry, produce modified particles by modification, modified particles is for the production of emulsion explosive-packaging tube, a whole set of technique has not only improved the efficient of aluminum-plastic separation reaction, and greatly reduce energy consumption, reduced pollution, extended simultaneously the industrial chain that the waste-old aluminium-plastic composite is recycled.
The present invention is take toothpaste aluminum-plastic composite packaging as raw material, agents useful for same is all nontoxic, produce and have high-quality vinyon product and aluminium powder, do not produce any industrial pollution in whole waste toothpaste aluminium plastic composite packaging recycling process simultaneously, have the characteristics such as cost is low, high efficiency, and nontoxic, process conditions requirement is low, simple to operate, environmentally friendly.
Description of drawings
Fig. 1 is process chart of the present invention.
The specific embodiment
Be described further technical scheme of the present invention below in conjunction with the drawings and specific embodiments:
As can be seen from Figure 1, technique of the present invention comprises following several step:
One, broken material is processed
Sorting: elect in waste product toothpaste is aluminum-plastic packaged, remove impurity;
Broken: the toothpaste of choosing is aluminum-plastic packaged, directly put into hammer mill and be with water to be broken into diameter at the fragment of 2-3 centimeters;
Clean: clean by cleaning equipment, the toothpaste of the aluminum-plastic packaged upper existence of toothpaste is cleaned up.
Two, aluminum-plastic separation
Soak and separate: the aluminum-plastic packaged broken material of the toothpaste that cleans up, join in aluminum-plastic separation equipment, then add aluminum-plastic separation to soak bleeding agent, at the temperature of 30 ℃～40 ℃, soaked 1～4 hour, then be warmed up to 50 ℃～70 ℃, insulation 30min;
Plastic-aluminum sorting: will add the plastic-aluminum screening installation through soaking the plastic-aluminum combined broken material after separating, aluminium is thoroughly separated with plastics.
Three, plastic granulating and finished product production
Dry modification: after the recycled plastic of separating cleans, through dry in centrigugal swing dryer dry after, add modifier through the row modification;
