Diseño y construcción de un laboratorio para ensayos de envejecimiento acelerado de materiales

Resumen

This project presents the design and construction of a laboratory for the simulation of the aging of fiber cement boards due to changes in temperature and humidity. For the development of the topic, the fundamentals of the design of industrial equipment are addressed, as well as the concept of temperature-accelerated aging chamber and its existing types; As relevant results, it has a fiber cement board manufacturing process by evasive fusion, which has a casting chamber with dimensions of 500 mm long, 275 mm wide and 10 mm thick and vacuum equipment with a range of 50 inHg, in addition to an aging team whose important aspects to know are; a hydraulic system which has passive elements such as pipes, tanks, check valves; actuators such as pumps and solenoid valves that allow the passage of spray water and activate the drainage to close the hydraulic circuit and the high and low level sensors, which are responsible for maintaining the chamber tank within the levels established for the tests; Given the conditions to which the chamber will be subjected, the use of stainless materials was considered for its construction, the maximum operating temperature is 110°C and to guarantee the homogeneity of the heat transfer inside the chamber, 2 special resistances are selected. of 750W at 110 V and a programmable control panel to select the desired test and two displays to show the duration and stages of each test.
