Product Description:

HDPE one method/two method polyurethane heat preservation pipe production line

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.

   2. HDPE One /Two step method polyurethane heat preservation pipe production line Isolate heat layer and anti-corrosion layer are wrapped on steel pipe at the same time, continuous production, high efficiency and low cost. In-line ball blast and de-rust, in-line painting and antirust treatment; In line complete automatic hydraulic deviation revising machine, high precision, stable and reliable. Multi-roller pressing transmission to convey steel pipe. Steel pipe range:Φ45-Φ1420mm.

Q:Plastics are processed into raw materials. How much raw material and energy do we need to process a kilogram of plastic?
Is the necessary equipment for extrusion blow molding machine, you must first set up the company, production workshop, production equipment, testing equipment, inspection personnel and production licenses for the government, as the raw material is plastic particles, costs and profits can not be known, see you how to operate.
Q:What kind of problems do we need to know about the new waste plastics recycling process?
Four major matters needing attention in investment of recycled plasticsPlastic recycling is a sunrise industry, the country, not only the effective utilization of resources and protect the environment, reduce the white pollution, from 2004 recycled plastics market, considerable benefits, as a new way of friends, is the author contact situation (editor's note), there are many aspects should be prepared in the first period, not to fight the battle without. The main problems are concentrated in the following aspects:1, blind follow-upAccording to the renewable materials market in 2004 prices, had been recycled most of the people have a better income, as for friends, in the test stage, on the surface has the advantages of simple process, low equipment investment, the product basically in short supply, technology content is not high, ordinary people can do at the same time, the raw material is us around the most familiar things, everywhere, everywhere can buy. Rough calculation, such as waste 2000 yuan can receive, the product can sell 4000 yuan, absolutely profitable.
Q:Where has the machine which sells the plastic processing, wants the true, begs the answer
What should I do? I have an injection molding machine here
Q:What plastic products can ABS be used for?
4. office equipment ABS has excellent impact resistance, good dimensional stability and rigidity. Forming, housing for manufacturing all kinds of office equipment, economic and practical. Such as fax machines, photocopiers, typewriters and computer monitors and other office equipment. The higher requirement on the fire, so usually are made of flame retardant ABS grade manufacturing.5. die model because ABS plastic machining performance, light weight, low price, in recent years has been widely used to mold model making industry, automobile, electronic appliances, machinery and equipment testing instrument. The rapid forming machine model Dimension is currently the world's most advanced ABS manufacturing standard stereo prototype as raw materials, then you can test of new product appearance, suitable degree and related functions. With the best price in similar products.
Q:What kind of equipment does the groove on the PP plastic board work on?
It can be machined with a shaper or engraving machine
Q:What plastics products are used in daily plastic products?
What do you want to see the plastic products, such as water pipes, electric wire slot need is extruder; plastic film, plastic bags and other needs is the film blowing machine; plastic bottle blowing machine; like most plastic stool, pots, barrels, and other appliances to the injection molding machine shell.
Q:The difference between plasticization and processability of plastics in extrusion process
I. Introduction of extruderIn 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 tube, rod, profile, also can be used for plastic modification and granulation. The basic mechanism of extrusion is very simple a screw in the cylinder to rotate and move forward the plastic. 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.
Q:What sewage treatment equipment should be used for waste plastics processing granules?
Waste water produced by processing plastic particlesFirst of all, determine the composition of sewage, and then according to the cost, floor space, water quantity, water quality, local effluent indicators, whether the effluent is used to determine the sewage process, and then use the equipmentYou said so simple, I think your sewage composition will not be too complicated, with integrated sewage equipmentA company can provide a three year warranty! Don't be cheap. Environmental protection will only get tighterAfter three months, the water is out of balance
Q:Is there a difference in melt index before and after processing?
If no additives are added during processing, the melt index is the same as that before processing.
Q:How much does it cost to process disposable plastic bags?
The package of blow molding machine, cutting machine, switchboard, mixing machine totaling about 120 thousand
