Polyurethane Composites

A teak leaf waste/polyurethane composite has been made for particleboard application. Some fraction variations are performed on the use of polyurethane as a matrix with a range of 0.04–0.20 (w/w). Mechanical and physical properties have been tested on the composites produced. The test results showed that the highest compressive strength of the sample reaches 38.5 MPa for polyurethane fraction of 0.14 (w/w). The composite has a density of 1261 kg m−3 which is in accordance with the result of density on teak. The physical properties have been also investigated and it was found that the lowest value of water absorption is 1.38%. This result indicated that the composites produced are potentially to replace wood raw material in eco-friendly industrial scale.

This study aimed to identify the effects of variety and composition of the adhesive used to the physical properties and the rate of combustion hyacinth biobriquettes. The physical properties referred to are water content, density and heating value. This research is an experimental study with a literacy study conducted in 3 stages, preparing tools and materials, making biobriquettes, and testing biobriquettes. The main ingredients used in the manufacture of biobriquettes are water hyacinth which is obtained at the Batujai Dam, Central Lombok Regency and the adhesive materials used are wheat flour, tapioca flour and cement. The method used to test the water content and density of the biobriquette was oven, while the calorific value and the rate of combustion were by heating water from the biobriquette combustion. The results showed that the biobriquette water content ranged from 5.138% - 13.953%, density 0.412 g/cm3 - 0.513 g/cm3, calorific value 2984.520 cal - 4476.780 cal, and combustion rate 0.029543 g/s - 0.042431 g/s. Based on the test results, it is known that the addition of adhesive material causes the water content, density, and combustion rate of the biobriquette to increase but the calorific value tends to decrease.
