Functions

High temperature compressive strength: The instantaneous strength of resin sand samples measured after being kept at high temperature for a period of time. This reflects the compressive strength performance of resin sand during pouring. The measurement method is to place the sample in a furnace that has been heated to a certain temperature, hold it for a period of time, pressurize the sample until it breaks, record the maximum load value, and calculate the maximum compressive stress.
Conditional thermal stability: also known as high-temperature duration, refers to the duration of resin sand maintaining its own strength at a certain temperature and load. Reflecting the ability of resin sand to resist metal thermal and mechanical effects, it indicates to some extent the thermal decomposition rate of resin binder and the strength of resin sand. The unit is s. The measurement method is to apply a constant load to the sample and quickly place it in a furnace that has been heated to a certain temperature, and then start timing until the sample collapses. The time from loading to sample collapse is called conditional thermal stability.
Limited thermal expansion force: The amount of load required to maintain the length of the specimen at high temperatures. Reflects the magnitude of internal stress generated by resin sand in a constrained state. The unit is N. The measurement method is to place the sample in a furnace that has been heated to a certain temperature, while keeping the length of the sample unchanged, record the magnitude of the force applied, and take its maximum value as the limited thermal expansion force.
High temperature expansion rate: The percentage of linear change between the sample's free expansion at high temperature and its original size (%)
