The Mooney Viscometer is the industry standard test for pre-vulcanisation properties and has long been synonymous with the rubber industry. Typically, Mooney Viscosity (MU) is used as a yardstick the gauge the quality of raw materials, especially in . Within the rubber industry, the viscosity of uncured rubber is expressed using Mooney Units (MU), an arbitrary, unitless scale that is measured using a Mooney Viscometer. Although this viscometer is specific to the rubber industry, the instrument and technique are firmly established throughout the rubber industry, with a long history of use. 아주 대표적인 평가 기기 Mooney Viscometer (무니 점도계)에 대해서 포스트를 해보려고 한다. 대표적인 무니 점도계는 아래와 같이 생겼다. 몇개의 경쟁사가 있겠지만.

Abstract The direct near‐infrared spectroscopic reflectance measurements of prevulcanized natural rubber (brown crepe) was employed for determination of its Mooney viscosity. NIR reflectance spectra were obtained for a total of 100 samples whose Mooney viscosity (VM in the range 68–95 units) have been determined by the standard reference .Superior Die Cooling and Temperature Stability – Thanks to low mass dies and proprietary digital temperature control, Premier MV delivers excellent temperature stability and a 45% reduction in die cooling time compared to previous models. Does your viscometer do that? Multi-Speed Measurement – Controls for multiple shear rates to establish power law curve and other shear .literature (Sherman, 1983) is the Mooney's equation (1951). Using functional analysis, Mooney derived the following equation to describe the relative viscosity/concentration behavior of rigid, spherical particles: T/, =exp[2.54>/(I-aM4>)) (1) where T/, is the relative viscosity, 4> is the volume fraction of the solids, and aM isCertifi cate No. 0395 Certifi cate No. 3088 Technical Specifi cations Design Spec.

It is interesting that the Mooney viscosity for one of the `bad' lots was very close to the Mooney viscosity for the `good' lot (ML1+4 of 93 vs 94). Table 11 gives a description of these three lots. Fig. 31 shows very good separation of the `good' vs the `bad' lots of natural rubber when comparing the uncured tan δ at high strain test conditions.MOONEY VISCOMETER MOONEYCHECK DRIVE Best Application: MOONEY VISCOMETER – MOONEYCHECK DRIVE The Mooney Viscometer – Mooneycheck Drive operates as a Mooney Viscometer, offering the capability to measure Mooney viscosity, Pre-curing (scorch), and Stress Relaxation Characteristics in both uncompounded and compounded rubbers.Features: High mooney viscosity & high ethylene content, high green strength & excellent extrudability, medium vulcanization speed & high filler loading.

Mooney viscosity ML()1 +4 100°C, but also by Mooney elasticity (a +1). 1. Introduction Natural rubber is a biopolymer originating in trees. Properties of this biopolymer are influenced by genetics of tree as well as by other factors. Characterization of . Traditional data-driven empirical models for online prediction of the Mooney viscosity have not utilized the information hidden in lots of unlabeled data (e.g., process input variables during each mixing batch). A simple semi-supervised nonlinear soft sensor method for the Mooney viscosity prediction is developed.
The results have shown that a change of 1 from the test temperature of 100 or 125 results in a 1.5-3% change in Mooney viscosity, depending on the type of rubber tested. 2.2.2. CLOSURE AND HOLDING PRESSURE During the test it is extremely important that the platens and dies be held closed with a force of 11500+500N.3 To obtain the correct .
