본 발명은 일정한 두께의 철판(아연도 강판)표리면에 동시적으로 일정한 두께(1m/mt)의 폴리에틸렌(P.E)시트를 접착하는 방법에 대한 것으로 종래에는 일단 철판으로 필요한 형상의 제품(예로서 파이프등)을 제조한 다음 P.E분말을 제품 표면에 포설한 다음 가열하여 P.E분말을 용융시켜서 제품표면에 용착되도록 하여 PE가 접착된 파이프등의 제품을 제조하여 왔다.The present invention relates to a method of bonding a polyethylene (PE) sheet of a constant thickness (1 m / mt) to the front and back surfaces of a certain thickness of the iron plate (zinc steel sheet) at the same time. Pipes, etc.) and then PE powder is installed on the surface of the product and then heated to melt the PE powder to be deposited on the surface of the product has been manufactured products such as PE bonded pipe.

종래 철판제품의 표리면에 P.E분말을 포설한 다음 가열하여 P.E분말이 용융되어 제품표면에 용착되게 하는 방법은 일예로서 파이프일경우에는 파이프를 가열하게 됨에 따르는 별도시설을 설치해야하는 경제적인 부담뿐아니라 P.E분말을 제품 표면에 포설할 시 분말이 주변으로 비산되어 환경오염등의 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 a conventional iron plate product and then melting the PE powder to be deposited on the product surface is one example. In the case of a pipe, not only the economic burden of installing a separate facility due to heating the pipe. When PE powder is placed on the surface of the product, the powder is scattered to the surroundings, making it difficult to manufacture a product that satisfies various problems such as environmental pollution and poor working environment and meets various specifications required by consumers.

When the iron plate (2) is horizontally charged from the (1) to the shot blaster (3), the shot is discharged at a high pressure by a plurality of injection nozzles (4) mounted up and down inside the shot blaster (3) The balls hit the front and back of the iron plate to cause the impurity such as the film adhered to the front and back of the iron plate (2) due to the impact impact. The iron plate (2) from the shot braster (3) continuously has high frequency induction. It is horizontally loaded in the heat (5) to instantaneously heat the front and back surface of the iron plate (2) at a constant temperature (temperature range 120 ℃ ~ 500 ℃), and the iron plate (2) heated to this constant temperature is rolled up separately at the top and bottom (6) Polyethyl of predetermined thickness wound in (6a) The PE sheet (7) (7a) is pressed on the surface and the back of the iron plate (2) by the upper and lower press rollers (8) (8a), and the polyethylene sheet contact surface is melted and attached to the front and back of the iron plate. (S) and a plurality of pressing rollers (10, 10a) are provided on the upper and lower sides via the PE sheet feeder (9) to be welded to the front and back surface of the iron plate (2) passing between the pressing rollers (10, 10a) A plurality of air nozzles 12 and 12a are pressed up and down through a pressing rolling machine 11 which compresses the polyethylene sheets 7 and 7a at a constant pressure up and down to maintain a uniform and strongly adhered welding surface. It is provided through the cooling tunnel (Cooling Tunnel) 13 to cool the high temperature inherent in the product material (S) by spraying cooling air from the air nozzle (12) (12a) to dissipate the latent heat of the product material (S) The product material (S) made of this board is wound with a winding machine (14) to complete and ship the product material (S) Tablets are constructed.

참고로 다양한 제품의 소재로 사용될 제품소재(S)의 구성요소를 설명하면 먼저 기재가 되는 철판(2) 표리면에 아연도금층(20)(20a)이 적층되고 아연도금층(20)(20a)외면에 전도성 폴리에틸렌층(HDPE)(21)(21a)이 적층되고 전도성 폴리에틸렌층(21)(21a)외면에 일반 폴리에틸렌층(22)(22a)이 일체로 고착된 구성으로 된다.For reference, when explaining the components of the product material (S) to be used as a material of various products, the galvanized layers 20 and 20a are laminated on the front and back surfaces of the iron plate 2, which is the base material, and then the galvanized layers 20 and 20a are external surfaces. The conductive polyethylene layers (HDPE) 21 and 21a are laminated on the surface, and the general polyethylene layers 22 and 22a are integrally fixed to the outer surfaces of the conductive polyethylene layers 21 and 21a.

상기와 같이 아연도 강판 표리면에 폴리에틸렌시트층을 고주파유도가열(高周波誘導加熱 : high - frequency induction heating : 나선형상으로 감은 도체에 고주파 전류를 인가하여 고주파 자계를 형성되게 하고 그 자계속에 놓인 도체의 와전류손에 의한 발열을 이용하는 기술)에 의하여 폴리에틸렌 시트를 철판에 접착하므로서 내식성 내구성등이 탁월한 폴리에틸렌시트피복 철판을 다양한 제품의 소재로 공급할 수 있을 뿐아니라 작업환경이 청결하고 접착시간이 대폭 단축되면서도 피복 표면 상태가 지극히 평활한 양질의 제품을 생산할 수 있는 효과가 있다.High-frequency induction heating (high-frequency induction heating): A high-frequency induction heating is applied to the conductors wound on the front and back of the galvanized steel sheet to form a high-frequency magnetic field, and the conductor is placed on the magnetic field. Technology that uses heat generated by eddy current loss) to provide polyethylene sheet coated iron sheet with excellent corrosion resistance and durability by attaching polyethylene sheet to iron plate, as well as providing a clean working environment and significantly shortening the adhesion time. It has the effect of producing a good quality product with a very smooth coating surface.
