AI Technical Summary
Existing diaper pad foaming materials suffer from poor foaming uniformity, difficulty in controlling cell structure, and insufficient stability in product thickness and porosity. Furthermore, traditional processes lack precise control over the dispersion of chitosan and nanocellulose, leading to a decrease in material degradability and mechanical durability.
Using raw materials such as nanocellulose, biodegradable matrix, bio-foaming agent, chitosan and softener, and through the precise and continuous control of high-speed dispersion homogenizing tank, gradient foaming reactor, casting and padding die head, gradient hot air drying pipe and calendering thickness fixing roller group, the gradient structure control and thickness uniformity of the material are achieved.
This technology enables the refined and continuous preparation of nanocellulose biodegradable foaming materials for diaper pads, improving the biodegradability and mechanical properties of the foaming materials and ensuring the uniformity of product thickness and porosity stability.
