Abstract

Spongy polyethylene is attached to a steel plate to prevent dew from forming on the rear surface of the plate, which is used as roofing material. The polyethylene is applied using a highfrequency induction heater at 170-200≰C and a 150 mm/sec plate transportation velocity. The spongy PE(2) is uniformly and densely attached through uniform heating and easy thermal control of the heater giving maximum thermal efficiency.

Description

도장강판(塗裝鋼板)에 스폰지상 포리에칠렌의 부착방법Method of attaching sponge-like polyethylene glycol to coated steel sheet

제1도는 스폰지상 포리에칠렌(Polyetlylene) 이 부착된 결로방지 지붕재 모형도.1 is a model of the anti-condensation roofing material with sponge-like polyethylene (Polyetlylene) attached.

제2도는 도장강판과 스폰지상 포리에칠렌이 이탈되는 상태도.2 is a state in which the coated steel sheet and sponge-like Pho ethylene is separated.

본 발명은 공장건물 등의 지붕재로 사용되는 결로(結露) 방지용 강판(鋼板)에 관한 거으로써 스폰지상의 포리에칠렌(Polyehtylene)을 칼라쉬트(Color sheet)나 염화비닐 코팅을 한강판 등에 부착하는 방법에 관한 것이다. 본 결로(結露) 방지용 지붕재는 주로 공장건물 등 외부와 온도차가 심하여 결로현상이 일어나 지붕재의 손상이 심하여 쉽게 교체하는 예가 허다하였다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel sheet for preventing dew condensation used as a roofing material of a factory building, and the like, to a method of attaching sponge-like polyhylene to a color sheet or a vinyl chloride coating on a steel sheet. It is about. This condensation preventive roofing material has a large temperature difference from the outside such as factory building mainly due to condensation phenomenon and damage of the roofing material was severe, and there were many cases of easy replacement.

종래의 공장지붕재는 칼라쉬트나 염화비닐 코팅한 도장강판(塗裝鋼板)을 그대로 사용하여 왔으나 공장 외부와 내부의 온도차에 의한 결로현상 때문에 지붕재는 산화가 심하여 자주 교체하여 막대한 비용이 증가 되었으며 또한 결로현상을 방지하기 위하여 두께가 2-3cm 정도의 스폰지상의 포리에칠렌을 접착제 등을 사용하여 부착하였으나 접착력이 약하여 쉽게 이탈현상을일으켜 실용화를 이루지 못하였다. 이들은 일반 포트식(Pot type furnace) 가열로에 의해서 열융착시켜 왔으나 노내의 특성에 의하여 일정온도의 관리도 어려우며 열편차가 생겨 고르게 부착되지 않아 이러한 접착부분의 연약성이 더욱 심했다. 이러한 방법에 의하여 제조된 결로방지 지붕재는 쉽게 접착부분이 탈락되어 결로 현상으로 인한 공장내 환경은 악화되고 하였다. 특히 접착제로 부착하는 방법은 부착공정이 많아 시간의 낭비는 물론 접착제가 고가품이며 인력 소비로 크기때문에 원가상승으로 인하여 더욱 실사용에 어려움이 있었다.Conventional factory roofing materials have used color sheets or vinyl chloride coated steel sheets as they are, but due to the dew condensation caused by the temperature difference between the outside and the inside of the factory, the roofing material is oxidized frequently and the enormous cost is increased. In order to prevent the phenomenon, 2-3cm thick sponge-like ethylene was attached by using an adhesive or the like, but the adhesive strength was weak so that it was easily detached and could not be put to practical use. They have been heat-sealed by a pot-type furnace, but due to the characteristics of the furnace, it is difficult to manage a constant temperature. The anti-condensation roofing material manufactured by this method was easily debonded and the environment of the factory due to the condensation was deteriorated. In particular, the method of attaching with an adhesive has a lot of attachment processes, which is a waste of time, as well as an expensive product and a large size due to manpower consumption.

이러한 종래의 방법으로는 부착된 결로방지용 지붕재의 결점들을 완전해결된 것으로 첨부도면에 의거 상세히 설명하면 다음과 같다. 결로 방지용 지붕재 본체(1)를 제조함에 있어 고주파수유도로(高周波誘導爐)를 강판상(鋼板床)과 같이 편형(編型)이 되게하고 열효율을 최대로 높이고 고주파로내 온도를 170℃-200℃ 범위로 하고 가압성형통판 속도를 초당 150미리로 스폰지상 포리에칠렌(2)을 융해부착하면 강판(3)과 스폰지상의 포이에칠렌(2)은 융해융착이 골고루치밀하게 부착되며 이 때 고주파 가열로의 열콘트롤이 용이함과 균일가열의 특성 때문에 균일하게 융착된다. 이때 사용되는 스폰지상 포리에칠렌은 불난연성(不難燃性)이기 때문에 이것의 융점이 220℃이므로 이온도 이하에서 행하여야 하며 변형온도가 170℃ 인것을 시험결과 알 수 있었다. 상술한 바와 같이 이러한 최적조건하의 부착방법을 얻기위 해서는 여러조건의 시험을 실시한 결과 그 시험조건과 시험결과는 표-1,표-2와 같다.This conventional method is described in detail based on the accompanying drawings as a complete solution to the defects of the attached condensation preventing roofing material as follows. In manufacturing the condensation preventing roof body 1, the high frequency water flow path is flattened like a steel plate, the thermal efficiency is maximized, and the temperature in the high frequency furnace is 170 ° C-200 ° C. If the fusion-bonded sponge-like polyethylene glycol (2) is melted at a pressure of 150 mm / s and the pressure forming plate is in the range, the fusion-fusion of the steel plate (3) and the sponge-like phoylene (2) is evenly adhered at this time. Thermal control is fused evenly due to the ease of heating and the uniform heating characteristics. At this time, since the sponge-like polyethylene glycol is nonflammable, its melting point is 220 ° C., so it should be carried out under ionicity, and the test result shows that the deformation temperature is 170 ° C. As described above, in order to obtain the attachment method under such optimum conditions, the test conditions and the test results are shown in Table 1 and Table 2 as a result of various tests.

이상과 같은 실험결과를 보면 유도로에 있어 각종 도장강판에 스폰지상의 포리에칠렌 부착방법으로는 고주파 유도로의 노내온도는 170-200℃이며 통판속도(通板속速度)는 150-160미리/초가 적합한 것이 입증되었다. 이상과 같은 조건하에서 각종 도장강판에 융착된 결로방지용 지붕재의 사용효과를 설명하면 융착이 균일하게 강도를 유지하며 별도의 접착재의 사용이 없어 원가도 대폭절감될 뿐 아니라 제조공정도 간소 화되어 대량생산에 적합할뿐 아니라 각종공장 지붕재에 사용시 고열작업의 공장에서도 도장강판과 스폰지상의 포이칠렌이 불리 이탈되는 일이 없어 도장강판의 수명까지 사용할 수 있어 아주 안가(安價)하게 결로방지용 지붕재를 생산할 수 있는 실용적인 포장강판에 스폰지상의 포리에칠렌의 접착 방법이다.According to the above experimental results, in the furnace, the furnace-like temperature of the high frequency induction furnace is 170-200 ℃ and the plate speed is 150-160mm / sec. It has been proved to be suitable. Explaining the use effect of the condensation prevention roofing material fused to various painted steel sheets under the above conditions, the fusion is uniformly maintained and the cost is not only greatly reduced due to the use of separate adhesive material, and the manufacturing process is simplified and mass production In addition, it is suitable for the roofing materials of various factories, and even in the factory of high-temperature work, it is possible to use the coated steel sheet and the life span of the coated steel sheet without any dislocation of the coated steel sheet and sponge-like poylene. It is a method of bonding sponge-like polyethylene glycol to a practical packaged steel sheet.
