A Study on the Polymer Blend Application Based on Natural Rubber Latex and Acrylic Resin as a Binder for Wall Paints| Chapter 4 | Research Aspects in Chemical and Materials Sciences Vol. 4

 The polymer blends established natural rubber tinted covering and acrylic sticky substance were created in this study. It was therefore used as a paint binder. The mixing ratios of open rubber latex and tinted covering resin ranged from 30/70, 40/60, 50/50, 60/40, and 70/30 (w/w), accompanying the natural elastic latex being pre-vulcanized before being blended accompanying acrylic resin. The survey was monitored through the tangible and mechanical properties of the blends. Highest stiffness and elongation at break were found at the synthesizing ratio at 30/70 (w/w) of normal rubber latex and tinted covering resin. Some tangible and mechanical properties as coagulate content and tensile property of pre-vulcanized unrefined rubber tinted covering, acrylic resin and each polymer blends were too investigated. This may be assign to the compatibility middle from two points elastic phase of the unaffected rubber and hard phase of tinted covering resin. When adjoining higher ratio of unrefined rubber latex, the stiffness and elongation at break discontinued continuously, indicating inhomogeneity of these two states. To confirm the compatibility of the blend at 30/70 (w/w), the coagulate content was also noticed. Using a high-performance cover results in a paint with excellent devotion. In this work, a polymer blend of natural elastic and acrylic resin in an best ratio was employed as a cover for wall paints. Unlike added blending ratios, this join totally dissolved in non-cold solvent. As a result, this synthesizing ratio is highly urged and suited for use as a paint cover.

A Detailed Experimental Investigation on IC Engine Using Alternate Fuels for Material Compatibility of Piping and Fitting System | Chapter 9 | Advanced Aspects of Engineering Research Vol. 5

 The entire world is concerned about the effects of environmental contamination these days, and car emissions as a result of the use of petroleum products are seen as a significant contribution to it. Because of its strong eco-friendly features, biodiesel has shown to be the greatest substitute for diesel. Despite the fact that biodiesel is a superior fuel than fossil fuel, the automobile industry is not ready to accept it due to a lack of study into material compatibility with biodiesel. This causes a delay in the adoption of fully biodiesel engines in autos. Biodiesel is made up of unsaturated fat esters, whereas diesel is made up of hydrocarbons. This study focuses on the experimental analysis of the influence of biodiesel on elastomeric materials used in automobiles, as well as the recommendation of acceptable materials in that field that are more biodiesel compatible. The approach entails immersing elastomeric materials such as NBR, CR, EPDM, Silicone, and Natural Rubber in biodiesel for 250 hours and analysing mechanical properties. The trials reveal that NBR > CR > EPDM > Silicone > Natural rubber is the best elastomer for biodiesel.

An Advanced Study of Quality Improvement of Natural Rubber Products by Drying Methods | Chapter 5 | Current Perspectives on Chemical Sciences Vol. 5

 The rubber industry relies heavily on a large number of inputs from the source of natural rubber (NR), which, due to its specific inherent properties, is one of the most used rubber materials. This experimental study was carried out to check the quality improvement of natural rubber products by drying methods and to determine to what degree the properties shown were affected by the different drying methods. During this analysis, natural rubber coagulum samples were collected and each sample was subjected to one of the following three drying methods: air, smoke and oven. The characteristics of the dried rubber samples from the three drying methods were then investigated. The quality parameter adopted in this analysis was the Plasticity Retention Index (PRI), which offered a measure of quality in terms of the oxidative resistance of natural rubber. By using the Wallace plastimeter, the plasticity retention index was tested. For the samples, the PRI values were determined. Results obtained from this analysis showed that, as shown in the PRI levels, the characteristics of natural rubber samples were actually affected to various observable levels depending on drying methods. The findings further provided the basis for our assumptions that smoke-dried rubber samples had the lowest qualities, with the lowest PRI values, followed by oven and air-dried samples, respectively, in terms of their PRI. The best features, as shown by the maximum PRI values. It would be recommended, on the basis of the results obtained from this experimental analysis, that the air drying of coagulated natural rubber samples should be carried out in preference to the other two alternatives and should be adopted as the drying method of choice wherever possible.
