Tannin Adhesive from the Mangrove Wood Branch of Black Mangroves (Rhizophora Mucronata) and Their Applications for Particle Boards

Introduction

Mangrove wood types of black mangroves (Rhizophora mucronata) are not only used as raw materials for charcoal production and construction poles, but they also store great potential as a natural source of adhesive. The mangrove bark contains tannin compounds that have many benefits, one of which is as an adhesive. Therefore, there is an opportunity to utilize the skin and mangrove wood more than just raw materials of charcoal, namely by extracting tannins from the wood to be used as adhesive in making particle boards.

The Potential of Mangrove Wood as a Natural Adhesive

Mangrove wood has been used for various purposes, including charcoal production and construction poles. However, its potential as a natural adhesive has not been fully explored. The mangrove bark contains tannin compounds that have been shown to have adhesive properties. Tannins are a type of polyphenol that are found in the bark, leaves, and roots of plants. They are known for their ability to bind to other molecules, making them a potential adhesive.

The Process of Making Particle Boards with Tannin Adhesive

The process of making particle boards with tannin adhesive begins with the preparation of raw materials involving tannin extraction. In this study, tannins were extracted from various sources: bark, wood, and a combination of both. The extraction process was carried out using a pressure pan at a pressure of 10-15 psi for 30 minutes at 116-121 ° C. After extraction, the process of making particle boards involves mixing wood powder with extracted tannins, previously mixed with 37% formaldehyde in a 10ml ratio. The next step is to make a pressing at a compression temperature of 150 ° C for 15 minutes.

The Results of the Study

The results of the study showed that the particle boards produced with tannin adhesive had poor quality or high vulnerability. To overcome this problem, phenol formaldehyde (PF) adhesive was added to the 50:50 ratio. The particle board produced had an average density between 0.62 to 0.65%. The water content varied between 10.14-11.88%, with water absorption between 117.69-144.20%, and the thickness of the thickness between 23.13-31.76%. Modulus of elasticity (MOE) ranges from 535.15-858.25 kg/cm², modulus of rigk (MOR) between 3.17-5.27 kg/cm², and the strength of internal bonds (IB) between 0.19-1.15 kg/cm². Although this particle board meets most of the physical nature conditions based on JIS A 5908 (2003) standards, the thickness of the thickness does not meet the criteria, while the mechanical properties do not reach the established standards.

Additional Analysis and Explanation

The particle board produced from tannin extraction offers an alternative that is environmentally friendly compared to the use of synthetic chemicals. The production process that utilizes local resources, such as mangrove wood, can reduce dependence on raw materials derived from further forests. In addition, the use of natural compounds such as tannins does not only have the potential to reduce environmental impacts, but also increases the selling value of the products produced.

Conclusion

Although the final result of this particle board shows some weaknesses in its mechanical properties, this can still be used as a foothold for further research. For example, by testing various comparisons and tannin extraction techniques, the quality of the particle board produced can be increased. Research can also include testing other types of mangrove wood, with the hope of finding variations that have a higher tannin content and better quality.

Future Research Directions

In the context of sustainability, utilizing resources such as mangrove wood also supports the conservation of rich coastal ecosystems. Therefore, further research in this field is very important to optimize the use of natural ingredients in the particle board industry, which in turn can create products that are more environmentally friendly and sustainable.

The Importance of Mangrove Wood in Coastal Ecosystems

Mangrove wood plays a crucial role in coastal ecosystems, providing habitat for various species of plants and animals. The conservation of mangrove wood is essential for maintaining the health of these ecosystems. By utilizing mangrove wood as a natural adhesive, we can reduce the pressure on these ecosystems and promote sustainable development.

The Potential of Tannin Adhesive in the Particle Board Industry

The use of tannin adhesive in the particle board industry has the potential to reduce the environmental impacts of this industry. Tannin adhesive is a natural and biodegradable adhesive that can replace synthetic adhesives. The use of tannin adhesive can also increase the selling value of particle boards, making them more competitive in the market.

Conclusion

In conclusion, the use of tannin adhesive from mangrove wood branches of black mangroves (Rhizophora mucronata) has the potential to create environmentally friendly and sustainable particle boards. Further research is needed to optimize the use of natural ingredients in the particle board industry, which in turn can create products that are more environmentally friendly and sustainable.
