Frequently Asked Question

To reduce the water absorption of the biodegradable nursery plant pot made from cassava starch bio-adhesive and grinded rubberwood sawdust filler, several modifications can be considered:

- Surface Coating: Applying a water-resistant coating, such as a wax or a thin layer of polymer, can create a barrier that reduces water penetration.

- Crosslinking: Introducing crosslinking agents into the bio-adhesive can enhance the strength and reduce the water absorption of the material.

- Filler Modification: Treating the grinded rubberwood sawdust filler with hydrophobic agents or using alternative fillers with lower water absorption properties can improve the overall water resistance.

- Additives: Incorporating water-repellent additives, such as certain types of clays or cellulose derivatives, into the composite can reduce the water absorption rate.

- Optimization of Formulation: Adjusting the ratio of cassava starch bio-adhesive to grinded rubberwood sawdust filler and optimizing the processing conditions can influence the water absorption properties of the final product.

- Blending with Other Biopolymers: Mixing cassava starch with other biopolymers, such as polylactic acid (PLA) or polyhydroxyalkanoates (PHAs), can improve the overall mechanical strength and water resistance.

- Layered Structure: Designing the plant pot with a layered structure, where the outer layer is more water-resistant than the inner layer, can provide better protection against water absorption.

Additionally, factors such as the size, shape, and porosity of the plant pot can also affect its water absorption rate. By optimizing these parameters and implementing the modifications mentioned above, it is possible to enhance the durability of the biodegradable nursery plant pot while maintaining its eco-friendly nature.
