A sulfate test chamber with a high-temperature resistant layer

Abstract

A sulfate test chamber with a high-temperature resistant layer is provided. The sulfate test chamber comprises a machine case, a test piece case and an electric control case. A water box, a refrigerating system, a heating system and a liquid feeding and discharging system are disposed in the machine case. A microcomputer is disposed in the electric control case and is used for system integration control of the systems in the machine case. Water streams in the water box are conveyed to the test piece case through the liquid feeding and discharging system after temperatures of the water streams are respectively adjusted by the refrigerating system and the heating system. A bracket is disposed in the test piece case. A test piece is disposed on the bracket. The high-temperature resistant layer is disposed on the inner wall of the test piece case and comprises a stainless steel liner layer, a high-temperature resistant mineral wool layer, a polyurethane high-temperature resistant layer and a surface layer. The high-temperature resistant mineral wool layer is disposed at one side of the polyurethane high-temperature resistant layer, and the surface layer is disposed at the other side of the polyurethane high-temperature resistant layer. The stainless steel liner layer is disposed at the other side of the high-temperature resistant mineral wool layer.

Description

technical field [0001] The invention relates to the field of building material test equipment, in particular to a sulfate test box with a high temperature resistant layer. Background technique [0002] The sulfate test chamber is designed and manufactured according to the requirements of the national standard GB / T50082-2009 "Standard for Test Methods for Long-term Performance and Durability of Ordinary Concrete". Special equipment for air drying, heating drying, drying heat preservation, cooling and other processes. The device can perform experimental functions such as parameter setting, communication setting, test control, data collection, data calculation, and real-time monitoring. However, since the test often alternates between cold and heat, the internal temperature is often difficult to be uniform, which often causes a temperature difference between the upper part and the lower part, thereby affecting the test data. Contents of the invention [0003] The technical ...
