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:Would you please use the collected nylon and plastic film to wash them and machine them?
The particles are collectively called colloidal particles". Mainly used in the quality of plastic products are not demanding. Such as cabbage tube, Christmas leaves etc..
Q:I want to find a rag processed into plastic granules manufacturers, can you help me?
You mean it woven rags! Use a plastic granulator.
Q:The manufacturing process of plastic products? Who knows?
(4) blow molding: hollow blow molding or hollow molding. Blow molding is resin parison with compressed air pressure in the heat of the closed mold blowing for a method of hollow products, including blow molding and blow molding hollow blown film products two methods. By blowing method can produce film products, all kinds of bottles, cans, pots and containers of children's toys.(5) calender is resin processing is expected to close by various additives (kneading, filter etc.) through the calender of two or more in favor of the opposing calender roll gap is processed into a film or sheet, then from the calender roller peeling off, and then by a molding method for cooling and shaping. Calendering is mainly used in the molding process of PVC resin. It can make films, sheets, plates, artificial leather, floor tiles and other products.(7) foaming material (PVC, PE and PS etc.) adding proper foaming agent to make plastic produce microporous structure. Almost all thermosetting and thermoplastic plastics can be made into foam plastics. According to the pore structure is divided into open celled foams (feel most connected with each other and closed cell foam pores) (most pores are separated from each other), which is mainly composed of manufacturing methods (including chemical foaming, physical foaming and foaming machine) decision. I hope it helps, thank you
Q:Where are home plastic products, plastic products for daily use, plastic products processing, plastic products, mold
You are looking for people to give you the processing mold, is it, then you go to the hook online to find ah, above doing this factory a lot
Q:I'd like to open a plastic bag factory. How much do I need to buy the equipment?
It depends on what plastic bags you need to make, and the size and size of the big plastic bags are also crucial. I make plastic bags.
Q:What is the function of adding filler in the processing of plastic products?
1., increase the strength: with glass fiber, can greatly increase the mechanical properties of plastics, tensile strength, bending strength, impact strength2., reduce costs: without reducing the strength of plastic, the addition of some fillers, such as talc, calcium carbonate, etc., can reduce the cost of plastics, but also increase the strength of the role.3., flame retardant effect: add flame retardant can be made into refractory plastic products.4. anti-aging: the addition of antioxidants can increase the anti-aging properties of plastics.5. lignite wax: to improve the flow of plastic, improve injection molding effect.
Q:What are the requirements for processing PET waste plastic bottles processing plant?
Then don't do it. Baidu can't support you in such a big deal. Because big bosses rarely disclose business experience on Baidu - find a reliable master or technician and learn from it
Q:I would like to do plastic crushing processing,
Different kinds of waste plastics have different characteristics. As far as impurity content is concerned, waste materials in the middle and outer corners of the factory produce impuritiesThe content of less than 0.1%, piled up scrap for a period of time and other products used for% impurity content 0.1 ~0.5%, mixed with aluminum, cloth and paper composite plastic waste impurities are often more than 10%. For used waste plastics,According to different use conditions, will include ultraviolet radiation, heat, oxygen aging effect, pollutants.Ring. For different shapes of waste plastics, the volume density of materials after crushing is very different, film, sheet, flatThe volume density of the crushing material is smaller, which is a problem that must be considered in the process of waste plastics recycling and granulation.Two. Pretreatment of waste plasticsFrom discarded packages, such as bags, shopping bags, bottles, cans, boxes and waste agricultural film waste plastics, inPretreatment prior to granulation. The pretreatment process mainly includes classification, cleaning, crushing and drying.Classification work is the classification of miscellaneous waste plastics products according to the type of raw materials and product shapes classification. By raw materialsClass sorting requires operators to have a good knowledge of identifying plastic varieties, and the purpose of sorting is to avoid different speciesThe resulting polymers are incompatible with recycled materials and have poor performance. They are classified according to the shape of the product to facilitate the use of waste plasticsThe crushing process can be carried out smoothly, because the film, flat and fabric used in crushing equipment with some thick and hard wareThe crushing equipment often can not replace each other.
Q:What kind of equipment and materials do you need for a plastic packing bag processing plant?
Film blowing machine, bag making machine, printing machine, raw material, PE granule, printing ink
Q:What are the machines needed for plastic processing???! Ten
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.
