II. Effect of Coagulants on the Quality of Rubber

Abstract. 1. Whatever coagulant is used for coagulation, a certain proportion of inorganic components, proteins and resins (1/9, 1/7, 1/5, respectively) of those originally present in latex remains adsorbed on rubber. 2. One-half of the total solids are eliminated with serum during coagulation. 3. The quality of rubber does not vary with a coagulant. 4. The molecules of latex

The binary classification model, which differentiates the industry-accepted formic acid-coagulated rubber cup coagulum from those which are not, exhibited satisfactory reliability, as evidenced by a 92% overall prediction accuracy and 71.4% cross-validation accuracy. Abstract A support vector machine classification algorithm was formulated to differentiate rubber cup

The percentage dirt of natural rubber is measured by dissolving a small sample of rubber in a rubber solvent, usually alongside a small amount of peptizer, at 125°C until the rubber has dissolved. This process generally takes about 3 hours.

Keywords: Natural Rubber production, Rubber products, Crepe Rubber INTRODUCTION Crepe rubber is coagulated latex that is rolled out in crinkled sheets and commonly used to make soles for shoes and boots but also a raw material for further processed rubber products. Crepe rubber is processed from fresh latex coagulum or cutting of Ribbed Smoked

1 INTRODUCTION. The rubber industry has experienced growth over time, reaching 30 million tons of rubber consumption per year in 2021, of which almost 14 million tons were natural rubber; this amounts to 2 kg of natural rubber per year for every person on the planet. [] Natural rubber is lauded for being a renewable resource and for being the most

Microbial communities in natural rubber coagula during

Aim: To characterize microbial communities present in natural rubber (NR) coagula from Hevea brasiliensis latex during maturation and identify microbial taxa (bacteria and fungi) having an impact on dry NR properties. Methods and results: Microbial community dynamics in NR coagula maturated under controlled conditions were compared and related with the evolution of dry NR

This review synthesizes the current knowledge on microbial populations in latex and natural rubber coagula of H. brasiliensis and the changes they induce on the biochemistry and technical properties of natural rubber during maturation. Natural rubber, produced by coagulation of the latex from the tree Hevea brasiliensis, is an important biopolymer used in
