- Q: Environmental impact of foam plastics reprocessing
- In addition, due to the difficult degradation of disposable plastic tableware, many cities are now promoting the use of green tableware - paper tableware, the principle is the composition of paper products, cellulose can be degraded by microorganisms. However, it is unwise to use paper tableware instead of foamed plastic tableware. First of all, paper tableware also brings visual pollution. Their degradation rate is not very fast, and they often do not degrade thoroughly in dozens of days or even months. Secondly, the paper tableware, in addition to straw pulp, rice pulp, but also to join about 1/3 of wood pulp, if fully promoted, will inevitably cause a large number of wood consumption, leading to deforestation intensified. But our country forest coverage rate is only 13.92%, the per capita forest area is only equivalent to the world average per capita level 17.2%. Third, the pulp system has always been a large water consumption, energy consumption and large sewage. The pulping process requires a great deal of water, while China is a country with a shortage of water resources. If the sewage is not treated and discharged into the river directly, it will cause water pollution. The paper tableware needs to be dried immediately after molding, which will require a great deal of energy. China's energy structure is dominated by coal, which will increase the content of SO2 in the air, causing acid rain.
- Q: How can we deal with the pollution of waste plastic particles?
- First of all waste plastics discarded in the environment is the environmental pollution, the recycling of this method to the society generally recognized. In addition to our impression of and also stop at the plastic granulator sewers, the pungent smell of stage. But now the situation has gone for ever. With the times and the progress of technology two kinds of pollution, all have a great improvement.

Preparation before moldingA, grain preheating and drying: if the grain is affected with damp, it should be dried;B, insert preheating: in order to reduce the gap between the cooling shrinkage value of metal and plastic, the larger metal insert should be preheated.C, barrel cleaning: when changing the product, changing the raw materials, cleaning cylinder is required.2, injection molding process feeding - plasticizing - injection - holding pressure - cooling - die opening piecesA, feeding: each feeding should be quantitative, in order to ensure uniform plasticization;B and plasticization: the grains are heated to a molten state in a barrel;C and injection: the injection molding machine uses a screw to inject molten plastic into the mold cavity;D, keep pressure: after the mold is finished, maintain the pressure for a certain time;E and cooling: keep cool for a certain time in the mold cavity;F, mold opening parts: mold open, take out the product.3, plastic parts after treatment: plastic parts after treatment:A, remove the fly edge, material handle.B, inspection and packing.
- Q: How are the plastic products made of this texture processed?
- FormingKey links in plastic processing. The various forms of plastic (powder, granular, solution or dispersion) made products or blank of desired shape. As many as 30 kinds of molding method. Its choice is mainly determined by the type of plastic (thermoplastic or thermosetting), the starting form, and the shape and size of the product. The commonly used methods for processing thermoplastics are extrusion, injection molding, calendering, blow molding and thermoforming. Thermosetting plastics are generally molded, delivered and molded by injection molding. Lamination, molding and thermoforming are the processes of forming plastics on a flat surface. The plastic processing method can be used for rubber processing. In addition, there are liquid monomers or polymers as raw materials such as casting. In these methods, extrusion and injection molding are the most widely used and the most basic molding methods.MachiningThe use of metal and wood processing methods, such as the manufacture of very accurate or small amount of plastic products, can also be used as molding auxiliary processes, such as extrusion section sawing. Because the thermal conductivity of plastic and metal and wood properties of different plastics, thermal expansion coefficient, low elastic modulus, when the fixture or tool pressure is too large, easy to cause deformation, cutting heat melting, and easy adhesion on the cutter. Therefore, the plastic processing, the tools used and the corresponding cutting speed, etc., should be adapted to plastic characteristics.The commonly used mechanical processing methods are sawing, cutting, punching, driving, planing, drilling, grinding, polishing, thread processing and so on. In addition, the plastic can also be used laser cutting, punching and welding.
- Q: What chemicals should be used in plastic products?
- Several commonly used plastic additivesPlastic additives can be divided into seven categories according to their specific functions: additives for improving processability, such as thermal stabilityA constant agent, lubricant, etc. Additives for improving mechanical properties, such as plasticizers, toughening agents, etc.. The changeAdditives for good surface properties, such as antistatic agents, coupling agents, etc.. Additives to improve optical properties, such asColorant, etc.. Additives to improve aging properties, such as antioxidants, light stabilizers, etc.. The reduction of plasticAn additive such as an extender, a filler, etc.. The specific effect of giving other additives such as foaming agent,Flame retardant and anti mildew agent etc..Additives are meant to be dispersed in the plastic molecular structure without serious impactA chemical structure of plastics that improves its properties or reduces its cost. Addition of additives, energyThe plastic can improve the processing, physical and chemical functions of the base material and increase the physics and chemistry of the base materialCharacteristic。
- Q: I would like to ask you how to produce plastic products, the need for mold, but also the need for large machinery, thank you all
- Plastic products according to the process can be divided into blow molding, plastic suction, extrusion, injection molding, etc.. Mineral water bottles are blown, the advertising light box characters are plastic, plastic injection of the most widely used, daily necessities, industrial production, most of which are injection molding products.No matter which process is needed, the mold needs to be produced. Their processing equipment is different, the most common is the injection molding machine. Then, some auxiliary equipments are needed for injection molding, such as mould temperature machine, cooling tower, air compressor and so on.
- Q: tooling mold design, processing, whether the need for quality certification system?
- Management system certification is basically looking at the enterprise's own needs, nor is it mandatory, but if you are here, if useful in the car, you have to do TS certification
- Q: The plastic bottle processing plant needs those machines
- The plastic bottle processing into extrusion blow and injection blowing, equipment, plastic bottle blowing materials are not the same, PE and PVC are PET bottles are extrusion blowing, injection blowing.First of all, to have bottle blowing machine, bottle blowing machine must also have the injection stretch blow moulding machine, extrusion blow without.A crusher is a bottle that breaks down and is used to crush bottles and recycle waste materials.
