Humidity influence Against MC

Understanding today's society most of the environmental impact of wood around the average was of the view that only the air temperature that makes change the wood MC. The hot air that will attract the water in the timber released into the air. This conditions which has the greatest influence. So, what about the wood in subtropical countries such as Europe or America? Subtropical countries tend to have cooler temperatures, but when we export furniture to it precisely control the MC problem should be more careful. Why? The key answer is in the air humidity. The air around us contains water vapor in the form of water, and especially the tropics such as Indonesia have air humidity high enough. In normal conditions, water content in the air is still far smaller than the water content in the wood while still wet so that when the wood dried in Kiln Dry, there are 'space' in the air to hold moisture. This is also one of the reasons why the air circulation system in the drying room should go well. When the rain season, air humidity drastically increased and to a certain point no longer space for the water vapor from the timber. If you have problems drying process is longer during the rainy season, not the other is due to air humidity. In certain cases even the wood that has dried on the level of 14% when placed in a damp cellar or outdoors, MC levels could go up to the level of 18% even 20%.

Absorber
Especially in the delivery schedule (exports) in the rainy season some plants to add some pockets' desiccant or absorber in the container to absorb moisture in the container. This silica bag capacity is about 3 - 5 times the weight of the bag.
Packaging
Planning a good packaging would help to save your wood products from damage due to MC levels is too high. Plastic is a good packing material to help protect the product from the influence of moist air back into the timber. But keep in mind that still needed some air holes for ventilation.
Relative Humidity
Simply, air humidity affects the level of MC can be seen in the following table. High and low air humidity will affect the maximum MC that can be achieved by the timber.

For example, if the surrounding air humidity is 80%, the MC-normal levels can be obtained is 18%, it is difficult to obtain a lower level because the 'space' to air live 20% water and when the air was 'saturated' is no longer able to hold water so that there is also the power to absorb water from the timber.
