Description:

1. Such three layer PE system mainly contains blasting section, coating section, inspection section and so on. The three-layer PE anticorrosion structure includes fusion bonded epoxy-powder bottom layer, polymer adhesive middle layer and polyethylene top layer. The epoxy powder is a kind of thermosetting nontoxic coating, forming the high molecular weight cross-linking structure coating after solidifying, featuring good chemical anticorrosion and higher mechanical properties. The function of epoxy-powder bottom layer is to form continuous coating, providing excellent adhesion by agglutinating and solidifying the steel tube surface with good chemical resistance and cathodic disbanding resistance. The function of polymer adhesive is to agglutinate the epoxy powder before gelation, and to agglutinate the polyethylene top layer, which unites all three layers together. The three-layer PE process, with the epoxy powder coating as bottom layer, binding and bundling through polyethylene PE and adhesive, is widely used in anticorrosion of steel pipes at home and abroad, and applied to the oil pipeline and gas pipeline, as well as to the gas supply and water supply for civil use.

Q: The next 5 to 10 years, small workshops waste plastics processing prospects for development?: China's plastic machinery industry production enterprises are large, most enterprises seriously deviate from the economic scale, production equipment backward, technical progress difficult situation is still serious. But some enterprises grasp the trend of market demand and technical development, through technical transformation effectively seize market opportunities, develop economic indicators of economic scale backbone enterprises begun to take place before the sort of product sales enterprises accounted for about twice the total domestic plastic machinery sales. So far, China's plastic machinery products are still medium, small as the mainstream, production has been in the world for many years.In 2012, China exported 69297 sets of plastic machinery, with a total amount of 1 billion 618 million 868 thousand US dollars, with an increase of 10.5% over the same period of last year, and the growth rate fell by 17.9% compared with 2011. Imports of plastic machinery 10482 units, total 2 billion 126 million 350 thousand U. S. dollars, the number of imports and the amount of year-on-year decrease, of which the amount of imports decreased by 2.4%. The year 2012 presses trade deficit of $507 million 485 thousand, compared with 2011 deficit significantly reduced.In 2013 the number of China machinery import 10052 units, the amount of imports of about $1 billion 820 million, and last year fell by 4% and 15%; exports, total exports in 2013 China machine 135213 units, the export amount of approximately $1 billion 720 million, an increase of 94% and 7% respectively.In the first half of 2014, China imported 4156 injection molding machines, an increase of 63%, and imports amounted to 398 million 650 thousand U. s.dollars, an increase of 18%.

Q: Types of plastic machinery: There are many kinds of plastic machinery. According to the processing process is divided into extruder, injection molding machine and blow molding machine three major categories. In the screw extruder is under the action of the molten plastic extrusion through fixed shape extrusion, water cooling after cutting in the traction machine under the same section is mainly used for a variety of products. A large number of continuous production, such as pipe, rod profiles, also can be used for plastic modification and granulation.The basic mechanism of extrusion is simple - a screw rotates in the barrel and pushes the plastic forward. The screw is actually a ramp or slope that is wound around the center layer. The aim is to increase the pressure to overcome the greater resistance. Is an extruder, there are 3 kinds of resistance to overcome: solid particles (feed) on the cylinder wall friction and screw rotation before laps (feed) the mutual friction between them; melt in the cylinder wall adhesion; melt pushed forward when the resistance of the internal logistics.It is divided into single screw extruder and twin screw extruder. The injection molding machine is injecting molten plastic into the mold, cooling after the product. The use is very extensive, according to the different use of plastic, where is different. The injection molding machine is used in processing machinery and plastic processing industry the largest amount, not only a large number of productsCan direct production of injection molding machine, and it is composed of injection stretch blow moulding equipment key.

Q: What kind of equipment do household workshops need to process plastic products? Can you make money? What are the sales channels?: The biggest investment is the injection molding machine, as well as three-phase power, it is best to understand the machinery will repair the mold, there is a stable processing order, you do not need to sell it!

Q: What are the processes and machines used in the manufacture of plastic products?,: In recent years, the proportion of plastic products is increasing rapidly in many fields, such as household appliances, instruments and meters, building materials, automobile industry, daily hardware and so on. The requirement of high precision and high performance of plastic products increases with each passing day, which makes the precision forming technology progress constantly. Injection molding is one of the most important plastic forming methods, and many factors affect the precision injection molding. 1. in the early stage of the design of plastic products, injection molding materials should be selected according to their application environment. 2. precision molds, rational design of precision injection mold is the basis and necessary prerequisite for precision products. Precision molds are indispensable to produce precision products. The precision of the die is usually affected by the temperature control of the die, the precise manufacture of the die and the choice of the plastic shrinkage when the die is designed. 2.1 control of the mold temperature due to the effect of mold temperature on shrinkage molding, but also directly affects the mechanical properties of plastic products, can also cause various defects of product surface flooding, so must keep mold in the specified temperature range, but also to make the mold temperature changes over time. In the injection molding of general precision parts, the temperature of the die is controlled mainly to increase productivity. But the impact of temperature control of mold for injection molding is great, it affects parts of the shrinkage, shape, crystallization, internal stress, so the design of mold hot loop temperature distribution at the request reasonable precise control accuracy, the best use of mold temperature machine and cold water machine control.
