Therefore, the flow of the melt is changed mainly from the pressure. 1, the treatment of plastics is due to the PET macromolecule containing lipid base, which has a certain hydrophilicity. The pellets are sensitive to water at high temperature. When the moisture content exceeds the limit, the molecular weight of PET decreases, and the products are colored and crisp. Therefore, it is necessary to dry the material before processing, and the drying temperature is 150, 4 hours, generally 170, 3-4 hours. The air - ejection method is used to test whether the material is completely dry. Generally, the proportion of the recycled material should not exceed 25%, and the recycled material should be completely dried. 2, PET is chosen for injection molding machine. Because of its short time after melting point and high melting point, it is necessary to choose injection system with more temperature control section and less friction heat when plasticizing, and the actual weight of products (water cut material) should not be less than 2/3 of machine injection volume. Based on these requirements, in recent years, Ramada has developed a small and medium-sized series of PET special plasticizing systems. The clamping force is selected by more than 6300t/m2. 3, mold and gate design, PET bottle embryo is usually molded by hot runner mold. Between the mold and injection molding machine template, it is best to have insulation panels, the thickness is about 12mm, and the heat insulation board will be able to withstand high pressure. The exhaust must be sufficient to avoid partial overheating or fragmentation, but the depth of the exhaust port is generally not more than 0.03mm, otherwise it is easy to produce the fly edge. 4, the temperature of the melt glue can be measured by air ejection method. At 270-295 degrees C, the enhancement level GF-PET can be set to 290-315 degrees C. 5, the injection speed is fast, and it can prevent the early solidification of the injection. But too fast, the high shear rate makes the material fragile. The ejection is usually completed in 4 seconds.

Generally not more than 100bar. It is usually not used. 7. Do not use too long detention time to prevent the decline of molecular weight. Try to avoid the temperature above 300 degrees centigrade. If the shutdown is less than 15 minutes. It is only required to do air - fire treatment; if more than 15 minutes, the viscosity PE should be cleaned and the barrel temperature is reduced to PE temperature until the machine is reopened.

The recycling company collected the bottles, crushed them into pieces or crushed them, and sold it to China at a relatively high price. According to the figures, a bottle of 16 liters of drink can be made into a sweater. Before 1993, all the plastic bottles were in the trash, a small part of the recycling. Since 4 years ago and the implementation of the tank fee, supermarket must recycle empty bottles, PET bottles, embarked on a journey to China, Wan Li: into synthetic crude wool sweater, and then returned to Germany, homecoming. China's textile industry has a huge demand for plastics. Although traders will add a bit more to the price of German recycling companies, imports are cheaper than their own raw materials. The transport from Hamburg to Hongkong was very low, because there were a lot of vacancies on the ship after the freighter came from China and unloaded the textile. The cost of production in China is very low, because the labor force is low, and the environmental and social standards are not perfect. In Chinese factories, these PET materials are classified according to color, cut into fragments and melted. After processing, PET bottles were returned to Germany in the form of textiles and sold in Germany. The value creation here is huge: a synthetic woolen sweater costs between 50 and 100 euros, and the material used is only 32 euro cents. The Far East can't see the end of the old plastic starvation. China has not been able to meet its needs with raw materials. In this context, second hand materials like PET are multiplied. Plastic empty bottles are used as raw materials in China, which shows that there is a world market of used raw materials in fact. 10 years ago, garbage was thrown into a garbage dump. "We were a consumer and discarding society." The example of China's processing Germany reselling illustrates the problem. "This market development shows to all consumers that some rubbish is indeed regenerated and reused."
