COMPOUND FOR SETTING RADIATORS OF HIGH-TEMPERATURE COMPARTMENTS AND LOW-TEMPERATURE CHAMBERS ON TUBES OF ABSORPTION REFRIGERATOR HEAT EXCHANGERS

摘要

The invention makes it possible to mechanize and automate the process of applying a retention composition to the tubes of the heat exchanger of the absorption refrigerator when pouring heat insulation from polyurethane foam. To increase the penetration and syneresis and thereby ensure the pumpability of the composition through pipelines, 520% by weight of petrolatum and 30-45% by weight of spun oil are used as an adhesive component, and talc in an amount up to 100% by weight of the composition is used as a capillary matrix. The components of the composition are mixed on any known two-rotor mixer, for example, 3 L 200-VRU, heated to 100 C about the camera. At the beginning, petrolatum and spun oil are loaded into the mixer, CO, and talc after melting of petrolatum. Mixing lead for 30 minutes. 1 tab.
