Abstract

The invention discloses a leather shrinkage temperature testing device which comprises a detecting box. A motor is arranged in the middle of the detecting box and connected with a driving shaft, the end of the driving shaft is provided with a stirring blade, the stirring blade stretches into the bottom in an electric heating cup arranged below the detecting box, an electric heating wire is arranged at the bottom of the electric heating cup, and a temperature sensor is further inserted into the electric heating cup. The problems that due to the punching fixing mode of a leather sample, the poor sensitivity of a Hall sensor and uneven heating medium temperature, leather shrinkage temperature testing is inaccurate, and certain deviation exists are solved.

Description

technical field [0001] The invention belongs to the field of leather physical parameter testing, and relates to a leather shrinkage temperature test fixing frame device. Background technique [0002] Shrinkage temperature is an important physical parameter test item of leather. Specifically, it refers to the ambient temperature corresponding to the moment when the leather sample begins to shrink and deform in a humid and hot environment with continuous and uniform temperature rise. It is an inherent characteristic of itself. By accurately detecting its shrinkage temperature, it will directly reflect the kneading condition and heat-humidity stability of the leather, provide data support for the determination of chemical materials and environmental conditions in the kneading process, and provide guidance for further processing and production of leather products or use selection . Although with the development of science and technology, there are many methods and devices for ...
