Mooney Viscosity Determination Of Rubber With A Charm Filler

Abstract

Research on the Determination of Viscosity Mooney From Rubber by Fillers Charcoal has been done. Each latex was added into the coconut shell charcoal ( particle size 80 mesh ) were 36 , 38 , 40 , 42, and 44 gram. Then the latex is coagulated with formic acid in pH 4.7. Formic acid is used as a control for the rubber crumple without the addition of coconut shell. Research carried out by measuring the quality of rubber Money Viscosity. From the results of research it turns out that the value of the viscosity of the money obtained by the addition of charcoal to the rubber in the latex is 72.5 ; 74 ; 75.5 ; 77 ; and 75. It can be seen that the value of the best rubber Mooney viscosity of 75 , so the rubber with medium Mooney viscosity value able to provide a meeting point between the energy efficient with superior physical properties .

A Predictive Adaptive Learning Method for Multivariable Time Series With Mooney Viscosity Prediction as an Application Case

“…L encoder (S i , S j ; φ, γ) (17) where µ is the weight hyperparameter, in the second term, we calculate the average distribution distance of all pairwise cycles. Formula ( 17) can be used to perform segmented training mechanism, and γ is learned by boosting based importance evaluation algorithm [23].…”

“…Mooney viscosity [17] serves as an intuitive feedback indicator for assessing the quality of rubber tempering, pivotal in determining whether the physical properties of rubber align with prescribed standards. Each stage of rubber tempering necessitates distinct processing operations, resulting in notable disparities in dynamic time series variables (e.g., capacity, current) and influenced by static characteristics of pre-tempering processing (e.g., raw material ratio, equipment number).…”

Kinetics Study of Gold (III) on Chitosan-Silica Coated Magnetic Material

“…Karakterisasi XRD dilakukan pada bahan magnetik pasir besi sebelum dan setelah dilakukan pelapisan silika-kitosan untuk melihat pengaruh pelapisan silika-kitosan terhadap fasa oksida bahan magnetik pasir besi. Perbedaan pola difraksi dari BMSK dibandingkan dengan bahan magnetik yang belum terlapis adalah adanya puncak melebar pada sudut 2θ = 20-27° yang menunjukkan keberadaan silika-kitosan yang bersifat amorf 15,16 . Selain itu, adanya penurunan intensitas kristalinitas juga terjadi setelah bahan magnetik dilapisi silikakitosan, misalnya indeks bidang [311] dari bahan magnetik belum terlapis dengan BMSK, seperti yang tersaji pada tabel 2.…”
