Have you ever encountered this phenomenon? White fluff appeared on the wood, and some were all over the box board. With the naked eye or 5 times magnifying glass, we can observe the colors of black, yellow, white, orange and green nettles. There are colonies with different colors and shapes, such as bud, ball and flake. In fact, these molds fall into two categories: Penicillium and Aspergillus. Let's take a look at the reasons why wooden furniture is moldy!

Excessive humidity

Using wet wood to make wooden pallet and wooden boards, in wet and rainy seasons, will be the main factors leading to mildew.

Main mold

The main molds are Trichoderma and Aspergillus Niger, which can cause green and black spots on the wood surface respectively.

The temperature is too high or too low

Mold can only grow in a certain temperature range, with its most suitable growth temperature, highest growth temperature and lowest growth temperature. The optimum temperature for fungal growth is 24℃ ~ 30℃, which is lower than 10℃ and higher than 40℃, the growth rate of fungi is slow.

Excessive moisture content in wood.

When the moisture content of wood exceeds 20%, mold can grow slowly; When the humidity of wood is above 35% and other growth conditions are suitable, mold will multiply in large numbers.

Remedial measures after mildew

Remedial measures after mildew generally include: drying, fumigation, heat treatment, anti-corrosion, mildew prevention, painting or varnish!
