ã€China Aluminum Industry Network】Aluminum alloy heat insulation profile is a compound profile with heat insulation function made of heat insulation material connected with aluminum alloy profile. It consists of aluminum alloy profile and heat insulation material. Aluminium alloy heat insulation profiles are divided into two categories according to their composite methods. One is to wear aluminum alloy heat insulation profiles, that is, through the open tooth, wear strips, rolling process, the strip heat insulation material wears aluminum alloy profiles Wear the inside of the groove and make it be firmly meshed with the aluminum alloy section to form the heat insulation section. The other type is a cast aluminum alloy heat insulation profile, that is, the liquid heat insulation material is injected into the aluminum alloy casting groove and solidified, and the temporary connection bridge in the aluminum alloy profile casting groove is cut to disconnect the metal connection through the heat insulation material. Insulation profiles that combine two parts of an aluminum alloy profile that are disconnected.
Inspection of aluminum alloy heat insulation profiles is generally divided into three major parts, namely inspection of aluminum alloy profiles, inspection of heat insulation materials, and inspection of composite aluminum alloy heat insulation profiles. The inspection items of composite aluminum alloy heat insulation profiles include dimensional deviation, surface quality, longitudinal shear test, transverse tensile test, torsion test, high temperature durable load test, and thermal cycle test, among which size deviation, surface quality, and longitudinal shear The cut test is an item that must be inspected in each batch. Transverse tensile test, torsion test, high temperature endurance load test, and thermal cycle test are periodic inspection items, that is, formal inspection.
Aluminum alloy heat insulation profiles commonly used performance testing equipment and devices:
1 Special shear tester for shear test;
2 (electronic) tensile (or hydraulic multifunction) testing machine for tensile and shear tests;
3 Test chambers for high temperature, low temperature shear, tensile and thermal cycle tests (high and low temperature environments);
4 Test chamber for high temperature durable load test;
5 It is used for special test fixtures such as shearing, transverse stretching and torsion test of heat insulation profiles.
