3PE anticorrosive spiral steel pipe process and construction requirements
The first step is to inspect and repair the anticorrosive steel pipe so that it meets the premise of the production of Ganzhou 3PE steel pipe and integrates various preconditions to repair the steel pipe.
The second step is to remove the embroidering on the steel pipe, use certain special raw materials to clear the rust on the surface of the steel pipe, so that the steel pipe is not eroded;
The third step is to wear the tube, and the rust-removed and anti-corrosion steel tube is sheathed in the polyethylene tube.
The fourth step is to repair the head and inject the polyurethane foam in the middle so that it can fully fill the hollow space between the steel pipe and the polyethylene pipe to make it become one;
The fifth step is the overhaul of the finished products. The completed finished products of Quzhou 3PE steel pipe are subject to overhauling. The products that meet the specifications are sold, and the unqualified products are refitted and improved.
The specific construction requirements for corrosion protection of steel pipes with anti-corrosion coatings are as follows:
(1) Good corrosion resistance, including chemical, atmospheric, water, acid, alkali, salt, and other solvents.
(2) Having good resistance to media permeability: The excellent shielding effect of heavy anti-corrosion coating requires the coating to have as low a permeability of water and oxygen and other corrosion factors as possible after film formation.
(3) Has good construction performance: The coating reaches a proper thickness, the thicker the coating, the better the shielding effect, of course, there must be a good structural design requirements.
(4) Good adhesion and physico-mechanical properties: Adhesion to steel pipe substrates or other substrates is a prerequisite for obtaining high-quality heavy-duty coating coatings, especially wet film adhesion and low shrinkage. Rate, appropriate hardness, toughness, wear resistance, temperature resistance and so on.
What is track lighting used for?
Led track lighting is a lamp installed on the track. There is no fixed space for the use of track lights. Whether it is commercial lighting or home lighting, it can be used. For example, the commercial lighting, whether the store can attract passersby into the store depends largely on the lighting effect. And LED Track Lights system can be very good lighting effect, can attract customers for your store. Because the Track Light system contains many types of lights, such as ambient lighting, accent lighting, and task lighting.
LED Track line lights and Slim Track linear lights belong to ambient lighting, with a relatively large illumination range to ensure the basic lighting of the environment. It is suitable for commercial places such as supermarkets and clothing stores to give the space a basic brightness so that the eyes can distinguish objects more comfortably.
COB LED Track Light belongs to accent lighting and task lighting. The position and irradiation direction of the Led Spotlight can be adjusted flexibly. Because of the focusing effect, it can better highlight the texture and details of the product and attract people's attention. Such as jewelry, counters, brand signs, window areas and merchandise display areas can use the Cob Spotlight.
