Detailed technical retardant polyethylene plates on; polyethylene retardant board uses a wider scope, in chemical engineering, power generation, coal processing, metallurgy, concrete, grain, mining, military, nuclear power plants and other aspects of the application is very extensive. So we want to do something polyethylene retardant board full understanding, here to talk about on polyethylene flame retardant board technology, the use of a wide temperature range polyethylene sheet, polyethylene sheet can be achieved through the use of flame retardant additives effect, the use of halogenated flame retardants in a very long time now because of the constant innovation of technology, there has been an inorganic filler flame retardant technology white polyethylene sheet, the study found, metal hydroxide Al (OH) 3, Mg (OH) 2 (need for crosslinking treatment) has a rich source of inexpensive, low smoke and toxic combustion, etc., become the most widely used non-halogen flame retardant. Another graduate output by adding a relatively small amount to the production of polyethylene intumescent flame retardant polyethylene panels are the results of flame retardant technology development board. More than one way of manufacturing polyethylene plate burning flame and low smoke, low toxicity, a better environment friendly. Welded polyethylene sheet divided into the following steps: First, ready for use before welding work, in accordance with the use of test welding method to determine the travel speed and hot wedge temperature. Second, the tape surface and the surface of the hot wedge welder on the wheel if there are hot melt adhesion of the impermeable membrane material residue or other debris, it will affect the quality of welding heat conduction and, therefore, must always clean, keep tape and heat wedge surface cleaning. Three, pe plate welds for two polyethylene sheet, each 10mm wide, the two middle seam about 15mm cavity to check the quality of welding. 2 as a weld quality to meet the requirements, while additionally a good wear polyethylene sheet, and may be due to thermal welding wedge is not perpendicular to the traveling direction, the hot wedge can be adjusted a little spring. Fourth, the tape up and down pressure welder wheel strut axle pressure generated by the agency, if the pressure is too small, resulting in slippage between the upper and lower wheels tape, if the pressure is too large, it will lead to increased friction resistance, welder difficult to walk, and even cassette phenomenon. Adjustment must be shut down when the pressure is inappropriate. Five, will be welded plates were inserted into the lower pe hot wedge of black polyethylene sheet by the left and right along the welding machine running direction, to be the temperature reaches 250 ℃ ~ 300 ℃, moving the roller handle automatic clamping pressure pe plates, welding machine forward, hot wedge surface melt adhesive waterproof board.
