In this study, we have intended to provide the related construction manuals with technical materials and to reduce the defects in the on-site construction, with reviewing the adhesive properties of joint parts according to change of temperature and speed of hot-air sealer for the products that have been made of polyvinyl chloride(PVC) materials in the single waterproof sheet. The result from the experiment is shown as following. 1) Bond strength was shown as high as the welding speed became slower. For the hot-air welding velocity with 3∼6m/min, a stable bond strength has been shown in the range of the hot-air welding temperature with 175∼210℃, while it has been shown in the range of the hot-air welding temperature with 210℃, when the hot-air welding velocity is between 9∼12m/min. 2) If the hot-air welding temperature is lower, the adhesive strength has been shown as higher in the section where the hot-air welding velocity is low, while the adhesive strength has been also shown as higher in the section where the velocity is fast as the hot-air welding temperature becomes higher. The highest bond strength has been shown in the velocity with 3m/min for the hot-air welding temperature with 140±10℃, which is rather low. At 175±10℃, a high bond strength has been shown in the velocity with 3∼6m/min, while the high bond strength has been shown in the velocity with 6∼9m/min at 210±10℃.
