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.

HDPE pipe range: Φ110-Φ1590mm.

Q: I am engaged in the plastic processing industry, mainly for ABS and PP through chemical agent for processing, will this be harmful to the body?: Alkyl tea sulfonate (ABS) can not only poison the body, but also promote carcinogenic effects of carcinogens. Recently, it has been found that ABS also has the risk of teratogenic changes.Polypropylene (PP) itself is non-toxic, but I do not know what you say powder ingredients, if there are plasticizers, masterbatch and the like, there is a certain toxicity.In the production of ABS containing detergent factory, should pay attention to do a good job of environmental protection, adopt cleaner type production process, in the production process to be closed, to reduce the concentration of ABS in the air of workplace and workers to do protective measures. Some large metal washing plants, paper mills, leather factories, food factories, etc., should be used in the use of mechanized operation, reduce manual operation, prevent long time direct contact with the skin. Pregnant women should change jobs appropriately so as not to influence the next generation. The waste water discharged by the factory should be discharged after the sewage treatment has been purified to meet the national discharge standard so as to ensure that our groundwater resources are free from pollution.

Q: What is plastic processing of moulds?: With the rapid development of plastic industry and the continuous improvement of general and engineering plastics in the field of strength, the range of application of plastic products is also expanding, and the consumption of plastic products is also rising.A plastic mold is a tool for the manufacture of plastic products consisting of a number of parts in which the molding cavity is formed. Injection molding, mold clamping in injection molding machine, the molten plastic is injected into the molding cavity, and cooling in the cavity shape, and then die down to separate out the system through the top products from the top of the left mold cavity, the mold is closed again for the next injection, the injection molding process is carried out of the cycle.The general plastic mould is composed of two parts, the moving die and the fixed mould. The moving die is installed on the moving template of the injection molding machine, and the fixed die is installed on the fixed template of the injection molding machine. In the injection molding, the moving die and the fixed die are closed to form a casting system and a mold cavity. When the mold is opened, the moving die and the fixed die are separated so as to remove the plastic product.

Q: How should be the material after refining to smooth feeding, shredders or other equipment?.: It seems that you are not made of plastic yourself, so don't do it blindly, so as not to make money, spend time, make a pile of waste, and then lose a lot.

Q: from raw material to particle forming, need several devices, what are they? _?: I also want to open such a factory, does the profit? I'm using scrap plastic as a particle here, so I want to check it out.

Q: Would you please use the collected nylon and plastic film to wash them and machine them?: I found that the 2 floor is the way out. Do not know their cloud ah.

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: What's the pollution of plastic processing to environmental protection?: From the ground floor to the surface, to the living to the sky, it is a full range of pollution!

Q: What kind of machine is needed for the production of plastic products?: Seventy thousand or eighty thousand an injection molding machine, a crushing machine, a drying machine forty thousand or fifty thousand, workshop, rent, labor, water and electricity to ten thousand months Duoliangwanyi, mold materials, another operator, of course cost large scale is low.

Q: Benefits of plastic products: 1., light quality 2., no rust 3., can be used to prepare fuel oil and fuel gas

Q: What equipment? How much money do not.. at first. There are several sets of injection molding machine can be about 2... Mainly plastic injection molding. The ABS PA PE PP PVC... Etc. in this area. Please know that a friend told Kazakhstan. Thank you.: Do PVC also dedicated screw, because PVC easily decomposed, and after the decomposition of the cylinder, screw, as well as mold are corrosive. Other material requirements are not high, so when you buy the machine, you must tell the manufacturer of your material.Equipment needed:1. injection molding machine2. pumps {pumps cooling machine mold, two units, the single-phase can be}
