Nylon is a material that is easy to absorb moisture. The toughness of fully hygroscopic nylon is about 8 times higher than that of dry nylon. Nylon can also increase its toughness to 1.5 to 2 times when it fully absorbs in the normal air environment, but it takes a long time to absorb moisture in the natural environment. In terms of nylon molecular structure, nylon molecules are water-absorbing molecules. Once saturated with water, the toughness of the material can be enhanced. The PA6 PA66 PA66/6 series has a higher water absorption rate.
The greater the proportion of amide groups, the greater the water absorption rate, and the product must be subjected to moisture absorption treatment after molding, so as to improve the reinforcement and toughness of the plastic parts of the product, and improve the mechanical properties. Wewon’s nylon products moisture absorption equipment is an environmentally friendly, energy-saving and high-efficiency equipment, which can accelerate the improvement of the moisture absorption efficiency of products in a short time.

Wewon’s nylon products moisture absorption equipment has changed the traditional boiling method and the pollution to the environment, Modification of nylon, strengthening and toughening without watermark, reducing enterprise cost, fast and stable moisture absorption. The main component of nylon material is polyamide, and the amide group (NHCO) is that nylon has both water absorption and dehydration double-sided properties. Nylon material without water absorption has strong brittleness. It is easy to break during the assembly process and cause unnecessary losses, but after saturated water absorption, the toughness of the material can be increased, and the dimensional stability can be improved at the same time.
Nylon products are generally placed in the natural environment (temperature 23°C, humidity 50%RH), and it takes 1 to 3 months for natural moisture absorption, but the use of Wewon’s nylon products with constant temperature and humidity water treatment can compress the moisture absorption time to within a few hours , so that nylon materials (PA6/PA66 and modified materials) can quickly reach a saturated moisture absorption state, and the materials treated by Wewon’s nylon products with constant temperature and humidity water treatment can be used directly without drying, wiping and blowing.
