本文简述了电视机用自熄性灌封料的研制情况,试验了各组份及其含量对性能的影响。本灌封料具有成本较低、配制方便、室温固化、电气性能良好、自熄性较优(符合94V—0级)等特点,已在19英寸及其它型号的黑白电视机行输出变压器灌封中应用。电视机行输出变压器中的高压线圈容易成为火源,导致整机烧毁。为了提高电视机质量,保障用户安全,必须首先对高压线圈
This article describes the development of TV sets with self-extinguishing potting materials, tested the impact of each component and its content on the performance. The potting compound has the advantages of low cost, convenient preparation, room temperature curing, good electrical performance and better self-extinguishing (complying with 94V-0 level), etc., and has been used in 19-inch and other types of black- In the application. TV line output transformer high voltage coil easily become a source of ignition, resulting in the whole machine was destroyed. In order to improve the quality of the television, to protect the safety of users, must first of high voltage coil
