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: this month bought a 180 thousand of the equipment and issued a value-added tax invoices, this sum of money can be deducted? How much deduction?Previously fixed assets are not deductible? Is this a policy that has just been changed this year? What's the tax rate? Thank you！: Can be deducted from the value-added tax invoices on value-added tax deductible, in addition to the purchase of equipment costs, if there are qualified transport documents, you can also by freight * 7% deduction of input tax

Q: Plastic blank in the gear hobbing machine processing, hob and workpiece is not to heat, then plastic is not easy to stick on the machine body.Just want to know the plastic gear processing technology is how, and ordinary steel gear processing technology difference where?.The more detailed, the better. Thank you: This problem, we have the right to speak, first of all, the plastic material relative to steel are quite soft, so the heating problem, processing on hobbing machine, the heat can be ignored, and, in the gear processing machine will have cooling facilities, to cool the workpiece. So this question, Louzhu worry too much.Also, plastic gears, casting molding, but also useful blank after cutting and forming, and this steel and gear is no big process difference......

Q: What is plastic processing of moulds?: Although the structure of the mold may be varied because of the variety and performance of plastics, the shape and structure of plastic products and the type of injection machine, but the basic structure is consistent. The mold is mainly composed of pouring system, temperature regulating system, molding parts and structural parts. The gating system and molding parts are in direct contact with the plastic parts and products as plastics and change, is the most complex in the mold, the biggest change, part of the processing requirements of the highest accuracy and smoothness.Pouring system refers to the flow of plastic from the nozzle into the mold cavity, including the main road, cold material hole, diversion channel and gate. Forming parts are parts of the shape of the product, including moving die, fixed mold and cavity, core, forming rod and exhaust port, etc..China plastic mould in promoting high technology driven and pillar industry application requirements, formed a huge industrial chain, from upstream raw materials industry and machining and testing equipment to the downstream machinery, automobile and motorcycle, household appliances, electronic communications, building materials and other major industrial applications, the development of a plastic mold vitality.With the rapid development of China's automotive, home appliances, electronic communications, building materials.

Q: How much does it cost to run a small waste plastics processing plant?: Hello, you need to tell me in which city and set up factories in general a small waste plastic particles Factory granulation machine and rolling machine related maintenance tools almost one hundred and twenty thousand or so this is the lowest level for the continuous operation of the workers to four hundred pounds or twenty total count down several flat covering but the mechanical and artificial need not one hundred and eighty thousand factory covers an area of such the words of small plastic granulation plant can take 25

Q: Which kind of engineering plastics has good processability?: Organic glass rods and plates, PTFE rod material, nylon rod, PVC sheet and other mechanical processing performance is good.

Q: Do waste plastics recycling processing, the state subsidies, and now the prospects are good?: Plastic machinery production of this piece, I personally think that Shandong is still a lot of production enterprises. All regions have done, and quite a lot, forming a production chain of processing. Shandong outstanding people, saints land, people are very real. Suggest that you go to Shandong site visits, compared to, not light, cheap, the most important thing is to look at the quality of the machine, after-sales service. Just like my friend bought a machine, the price is not very cheap, but the quality of the machine is good, and there is nothing wrong with it.

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.

Q: Want to buy an injection molding machine to do some plastic products, equipment about how much money ah? What needs to be prepared?: Used cheap, close to the product will also be very cheap

Q: Why is the dimensional accuracy of molded plastic parts much lower than the accuracy of machined products?: Therefore, the precision of plastic products is lower than that of machined products by 1~2 grades.
