본 발명은 일정한 두께의 철판(아연도 강판)표리면에 동시적으로 일정한 두께(1mm)의 폴리에틸렌(P.E)시트를 접착하는 방법에 대한 것으로 종래에는 일단 철판(예로서 파이프등)을 제조한 다음 P.E분말을 제품 표면에 포설한 다음 가열하여 P.E분말을 용융시켜서 제품표면에 용착되도록 하여 P.E가 접착된 파이프등의 제품을 제조하여 왔다.The present invention relates to a method of bonding a polyethylene (PE) sheet of a constant thickness (1 mm) simultaneously to the front and back surfaces of a certain thickness of a steel sheet (zinc steel sheet). The PE powder was laid on the surface of the product and then heated to melt the PE powder to be deposited on the surface of the product to manufacture a pipe such as PE bonded.
종래 철판제품의 표리면에 P.E분말을 포설한 다음 가열하여 P.E분말이 용융되어 제품표면에 용착되게 하는 방법은 일예로서 파이프일 경우에는 파이프를 가열하게 됨에 따르는 별도시설을 설치해야하는 경제적인 부담뿐 아니라 P.E분말을 제품 표면에 포설할 시 분말이 주변으로 비산되어 환경오염 등의 문제점과 작업환경이 열악하고 소비자가 요구하는 다양한 사양을 만족하는 제품을 제조하기가 현실적으로 어려운 실정이다.The method of installing PE powder on the front and back surfaces of conventional iron plate products and then heating the PE powder to be fused to the surface of the product is an example of the economic burden of installing a separate facility due to heating the pipe in the case of a pipe. When PE powder is placed on the surface of the product, the powder is scattered to the surroundings, making it difficult to manufacture products that meet the problems such as environmental pollution and poor working environment and satisfy various specifications required by consumers.

(2) The front and back surfaces are sequentially heated to a constant temperature (temperature range 120 ° C. to 500 ° C.), and the iron plate 2 heated to the constant temperature is wound on the winding rolls 6 and 6 a separately. The polyethylene sheet (PE sheet) 7 (7a) of the predetermined thickness is formed on the surface of the iron plate (2). Pressed by the up and down pressing ruler (8) (8a) while the polyethylene sheet contact surface is attached to the iron plate front and back while melting the product material (S) through a plurality of compression rollers (10) through the polyethylene sheet feeder (9) 10a is provided on the upper and lower sides, and the polyethylene sheets 7 and 7a welded to the front and back surfaces of the iron plate 2 passing between the pressing rollers 10 and 10a are pressed at a constant pressure from the top and bottom to form a weld surface. A plurality of air nozzles 12 and 12a are provided on the upper and lower sides through a welding process passing through the pressing rolling machine 11 to uniformly and strongly adhere and maintain the product material (S). Passing through the cooling tunnel (Cooling Tunnel) (13) for cooling the high heat inherent in the) leads to a cooling process to dissipate the latent heat of the product material (S) winding the product material (S) made of this plate (14) Finished product material (S) by winding process In addition, the entire process is carried out so as to be shipped. In addition, as illustrated in FIGS. 2 and 3, the components of the product material S to be used as materials of various products are first described. The plating layers 20 and 20a are laminated, and the conductive polyethylene layers (HDPE) 21 and 21a are laminated on the outer surface of the galvanized layers 20 and 20a, and the general polyethylene layer is formed on the outer surfaces of the conductive polyethylene layers 21 and 21a. 22) 22a becomes an integral structure. In this way, the inner layer of the polyethylene sheet 7 (7a) to the front and back surfaces of the iron plate (zinc-plated steel) is the conductive polyethylene layer (21) (21a) and the outer layer is composed of the general polyethylene layer (22) (22a). It is not only easily melted and coated by the conductive polyethylene layers 21 and 21a on the front and back surfaces of the iron plate (zinc steel sheet) heated to a predetermined temperature (120 ° C. to 500 ° C.) in the high frequency induction heater 5. This is because the polyethylene layer 22 (22a) can obtain a high quality surface having a very smooth coating surface state.
