Design of experiment of material level settings on the factors affecting the quality of calcium silicate board by using the Taguchi method

Abstract

The main purpose of this paper is to identify and determine the level of regulation on factors that influence the type and characteristics of the pulp so that it can produce optimal quality Calcium Silicate Boards. The experiments were carried out using the Taguchi method and using quality characteristics: strength, deflection, density, and water absorption. Then, the factors that influence product quality are the use of pulp percentage, pulp type, and pulp composition. Data processing uses two analyzes to determine the optimal level setting, which consists of mean analysis and signal to noise ratio analysis, then an experiment is carried out to confirm the predictive value of the level setting factor under optimal conditions. The results showed that the type and composition of the pulp affected the strength and density of the product, the use of the percentage of the pulp affected the deflection of the product, and all factors did not affect the absorption of product water, with an optimal level of regulation: 9.8% percentage of pulp, Y type of pulp, and 100% pulp composition. Confirmation results obtained an average value of the strength test was 154.5 kg / cm2, 13 mm for the deflection test, 1.3275 g / cm3 for the density test and 36.35% for the water absorption test.
