变压器中柱用什么胶？

很多变压器磁芯中柱开气隙后要求点胶,点胶主要是减震降低嗓音，防止磁芯在磁场的作用下发生震动而产生的噪声

降低变压器本体噪声,平稳、隔振调整

那变压器磁芯中柱用什么胶好呢？考虑到磁芯的易碎及电感的敏感性，行业上大部分采用的是软性的环氧树脂胶水，此类胶水固化后柔软，胶水自身应力较小，因此很适合中柱的填充，对磁芯及电感的影响很小。

Many transformer cores require glue after the air gap is opened. The main purpose of glue dispensing is to reduce the noise caused by vibration of magnetic core under the action of magnetic field

Reduce the transformer body noise, stable, vibration isolation adjustment

What kind of glue should be used for the core of transformer? Considering the fragility of the magnetic core and the sensitivity of the inductance, the soft epoxy resin glue is mostly used in the industry. This kind of glue is soft after curing, and the stress of the glue itself is small. Therefore, it is very suitable for the filling of the central column, and has little influence on the magnetic core and inductance.

Huachuang materials magnetic core column special one component soft epoxy resin adhesive, for the magnetic core structure research and development, nearly 15 years of market application, stable quality, excellent performance.

The range of hardness can be adjusted, and the hardness can be reduced or increased according to the actual product requirements, and the viscosity curing time can be adjusted according to the requirements.

1. Viscosity adjustment: from high fluidity to no flow

2. Curing time: adjustable curing time and quick drying (affecting storage life)

3. Hardness adjustment: the hardness can be adjusted from 20d to 80D

4. Function adjustment: adjustable thermal conductivity; thermal conductivity adjustable range: 0.3-1.5
