The waste plastics that have been sorted and selected can be put into a plastic pulverizer for pulverization and cleaning. Generally, a plastic pulverizer with a cleaning dragon is used. A bracket with a height of about 1.5 meters is placed next to the pulverizer, and a bucket is placed on it.

There is an alkali solution or detergent inside, and a pipe with flow control is used to custom waste plastic recycling machine introduce the detergent into the plastic pulverizer, so that during the pulverization process, the detergent (and a pipe to add clean water) and waste plastic are contained in the pulverizer. After sufficient rubbing, the pulverized material from the pulverizer directly enters the cleaning pool. The general size of the cleaning pool is more than 8 meters long,

1.2 meters wide and 1 meter deep. There are sewage holes at the bottom of the pool, and 3 to 4 guides need to be installed on the cleaning pool. The diversion device for the flow direction of the pulverized film material. The diversion device can evenly distribute about 10 four holes on one side of the 6-point pipe. For directional flow, an automatic feeding machine is installed at the other end of the cleaning tank, so that the crushed material flowing in a directional flow is sent to the drainage area to be processed by the automatic feeding machine.

Material forms commonly used in plastic molding

l There are four commonly used material forms in plastic molding: powder, pellet, solution and dispersion, of which powder is the most used. l This chapter mainly introduces the working principle, preparation method and molding process performance of each component in thermoplastics.

Plastic Pseicle Machine is a granulation machine, mainly for processing waste plastic film (industry Packaging film, large shed, agricultural film, handbag, beer bag, etc.), agricultural convenience bag, woven bag, bucket, pot, fuiture, beverage bottle, daily necessities, etc., suitable for most common waste plastics, is a waste plastic regeneration industry The use and use are a wide range of equipment, and it is also very popular in plastic regeneration machinery.

Plastic pellet machine becomes a very popular plastic regeneration machinery? Special screw design and different configurations are used to produce regeneration and mixing granulation of various  Plastic Granule Cutter plastic products such as PMMA. The gearbox is selected for high torque design, ending without noise operation and other performance. The screw, the cartridge is specially hardened, has the characteristics of wear resistance, high yield, good kneading performance, vacuum exhaust or ordinary exhaust port, can take moisture, exhaust gas in the production process, make the collapse more Strong, the discharge is more stable, ensuring excellent quality. Plastic pellet machine is divided into manual and electric, and the granulator needs often change the net to remove impurities. The extrusion mold is generally 18 holes. After the filter is blocked, the pressure is large, the original manual change network will be more tired, can use electric mold equipment production efficiency is high, the functional facilities should be perfect, the degree of automation is high.

5, the energy saving of the plastic granulator, environmental protection is an indexable indicator. Energy saving, mainly reflecting the plastic granulator in the power drive system, cleaning system, heating system, and cooling system to meet the water saving and power saving capacity of comparison with similar machines under normal process conditions. 6. The humanity design and operability of plastic granulator are also an important indicator of the quality of equipment.

The energy saving of the plastic granulator can be divided into two parts: one is the power part and the other is the heating part. Energy saving in the power part: most of them use frequency converters. The energy saving method is to save the excess energy consumption of the motor. For example, the actual power of the motor is 50Hz, and you actually only need 30Hz in production. Wasted, the frequency converter is to change the power output of the motor to achieve the effect of energy saving. Energy saving in the heating part: Most of the energy saving in the heating part is the use of electromagnetic heaters to save energy, and the energy saving rate is about 30%-70%  wholesale Plastic Shaker Manufacturers of the old-fashioned resistance coil. 1. Compared with resistance heating, the electromagnetic heater has an additional layer of insulation layer, which increases the utilization rate of heat energy.​​

2. Compared with resistance heating, the electromagnetic heater directly acts on the heating of the material tube, which reduces the heat loss of heat transfer.​​
3. Compared with resistance heating, the heating speed of the electromagnetic heater is more than a quarter faster, which reduces the heating time.​​
4. Compared with resistance heating, the heating speed of the electromagnetic heater is fast, the production efficiency is improved, and the motor is in a saturated state, which reduces the power loss caused by high power and low demand. The above four points are the reasons why the electromagnetic heater can save energy as high as 30%-70% on the plastic granulator.

      It is not easy to identify intuitively. The following method is simple and easy to implement: Tear the film and observe the fracture. If there is a sawtooth shape, it is generally a composite film; if the cross section is relatively smooth, it is a single-layer film. Wipe the side of the film with ink on the rougher surface for a few times. If the ink falls off, it is generally a single-layer film; if the ink cannot be wiped off half, it is a composite film. Ignite the film, if there is no characteristic odor, or there is a wholesale Plastic Shaker for sale mixed odor, it is either a composite film; either a copolymer or a blend.
      Identification of plastic films There are many types of plastic films, especially the port materials are more complex, and the identification of materials is very important. Easy to stretch film PE, PP (unstretched), soft PVC is not easy to stretch; heat and melt, heat shrinkage; stretch PP, stretch PVC, polyvinylidene chloride, PS is not easy to stretch; heat and melt; heat shrinkage Polyester and nylon are not easy to stretch; heat does not melt - cellophane to take a film to test its stretchability; another film sample, slowly approach the flame, observe its heat shrinkage and whether it melts.

 Heating identification method Put a small amount of sample into a glass test tube, heat the test tube slowly on the flame, and when the sample is decomposed, take a piece of soaked precision PH test paper and place it at the mouth of the test tube, and measure the pH value of the decomposed gas. PH=0.5 -4.0 Chlorine, bromine-containing polymers, polyvinyl esters, phenolic resins, polyurethane elastomers, fluoropolymers, polysulfides. PH=5.0-5.5 Polyolefins, polyvinyl alcohol, polyvinyl ether, polymethacrylic acid Ester, polyoxymethylene, polycarbonate, linear polyurethane, cross-linked polyurethane. PH=8.0-9.5 Nylon, ABS, acrylic Note: Modified materials will affect identification; halogen flame retardants will also affect identification.
