Report of passing year survey of heat insulations and waterproofing at heat storage tank

Abstract

This report shows passing year survey of heat insulations and waterproofing at heat storage tank that constructed by PVC resin sheet. As a result, aging waterproofing sheet was shown that still remained the function of tensil strength and coefficient of extension yet. Furthermore, many part which heat insulations transformed was escaped damage of waterproofing by the favor of PVC sheet’s extension. From this, it is important that makes clear the function of PVC sheet’s extension and criteria for selection of thermal insulation to be used. A futre subject is positive accumulation of data and examined experimental validity on that materials.
