Have you ever seen moldy objects? Tell me why they become moldy.

I would like to introduce you to the four major factors for mold growth:

1. Mold must be in contact with the air. It is difficult for mold to reproduce under vacuum conditions. For example, food packaging uses vacuum aluminum film packaging.

2. Mold needs a suitable temperature and humidity to reproduce in large quantities. For example, in a dark and humid place, water molecules will penetrate into the object or attach to the surface of the object. The reason why the product humidity exceeds the standard is the highest factor of mold, but it is also a link that can be controlled by humans at low cost.

3. Mold is a kind of microorganism and also needs a nutrient source, such as starch in glue. , protein, oil in leather and fiber in wood are all nutritional sources for mold.

4. Mold is everywhere, in the air, dust, soil, and sweat, and it is particularly easy to Stay on some uneven surfaces, such as product seams, fabric and wood surfaces.
