Packaging steel strip polyester belt performance analysis

by:Hongmei     2020-07-04
Packaging steel strip polyester belt on the tensile strength and toughness are enough to meet the needs of the iron core of binding, on the insulation, heat resistance, transformer oil resistance are through strict inspection, had no other effect on product performance. Here are using thermogravimetric method on the thermal stability of insulation test: decomposition temperature ( ℃) 一个= C - 3/7 ( B - C) The heat index ( ℃) Tg=( A + B) / 2 x B: 50% lost key temperature ( ℃) C: 15% lost key temperature ( ℃) Results: B = 406. 70℃,C=375. 58℃,= 362。 24 ℃, heat resistant index: Tg = 179. 66℃( X = 2。 14) ; Tg=170. 12℃( X = 2。 26) ; Tg=162. 22℃( X
