How to deal with the moisture problem of SMC szigetelőlap nyersanyagok

In order to ensure the better quality of the SMC insulation board, it is necessary to dehumidify its raw materials. The following content will give you a detailed explanation of how to dehumidify the raw materials of the product. Please understand it carefully.

There are two kinds of drying equipment for SMC insulation board raw materials, namely hot air dryer and dehumidification dryer.

The principle of the hot air dryer is to use hot air to blow away the moisture in the raw material of the SMC insulation board. The temperature range is 80-100c, and the drying time is mostly 40-60min.

The principle of the dehumidification dryer is to replace the moisture in the hot air with molecular sieves, and then use the drying air to blow away the moisture in the raw materials of the SMC insulation board. Using this method, the moisture in the raw materials can be reduced to less than 0.1%, and the drying temperature is generally At 80-100oc, the drying time is generally 2-3h, and a dryer with stable performance can reduce the dew point of the drying air to below -30°C; if the moisture content in the raw material is greater than 0.08%, a hot air dryer needs to be used for pre-drying.

For the demander of SMC insulation board, the level of drying equipment is an important factor to judge whether the product with stable quality can be produced.
