| | Rubber Mixing | £250.00 | | Rapra Polymer Bulletin |  | | This Polymer Bulletin is a current awareness service from the Polymer Library, the world's largest database dedicated to polymer literature. Each time the abstracts database is updated with new records (approx. every two weeks) you will be sent a bulletin alerting you to any items that relate to rubber mixing. Please see the sample issue below (request further samples)
The art of mixing in the rubber industry has a long history. The origins of the modern mixers in use today can still be clearly traced back to the earliest practical internal mixers developed as long ago as 1916. Mills are also still used extensively for certain compounding applications, and these employ principles that date back still further. Nonetheless developments continue to be made. Increasingly demanding applications for rubber components necessitate improvements in quality, better dispersion, high uniformity and perfect reproducibility. There have been many advances in rotor designs, as well as in drive systems and temperature control, and whilst mixer performance is clearly the most important factor in controlling compound quality, ancillary equipment (supply and downstream) also has an important role to play.
A Current Awareness service from Rapra may be just what you need to update your knowledge with ease and accuracy without having to waste time, effort and money finding the information yourself.
If there are many people within your organisation who would benefit from this information then get in touch to talk to us about our multi-recipient bulletin. | | | | Format: Annual subscription, E-mail delivery every 2 weeks, Variable no. of records | | ISBN: | | |

MODELING AND PRACTICE OF ETHANOL-DEVOLATILIZATION OF SILICA-SILANE RUBBER COMPOUNDS IN AN INTERNAL MIXER.
Dierkes W; Noordermeer J W M
Twente,University
The development of a mathematical model for ethanol devolatilisation of rubber compounds containing silica and silanes during internal mixing is described. The model is based on the penetration theory and includes a chemical reaction replenishing the volatile component during devolatilisation. Mass transfer between the surface layer of the polymeric material and the vapour phase is considered to be the main contributor towards devolatilisation. 18 refs.

STUDY OF RHEOLOGICAL PROPERTIES OF RUBBER/CARBON BLACK COMPOUNDS DURING INCORPORATION STAGE IN INTERNAL MIXERS: A MIXING DEPENDENT APPROACH.
Ravati S; Ghoreishy M H R; Bakhshandeh Gh; Souraki F A
Iran,Polymer & Petrochemical Institute
A rheological study was carried out into the initial mixing of SBR with N330 carbon black in an internal mixer using a rubber process analyser. The content of carbon black in the rubber compound was calculated using three parameters (agglomerate radius, mixing time and initial filler volume fraction) and scanning electron microscopy was utilised to determine mixing stages and decreasing carbon black/rubber agglomerate sizes. Using the data obtained, a relation for predicting the effective filler volume fraction based on the initial volume fraction, mixing time, agglomerate radius and rheometer frequency was derived. 11 refs.

FAST ROUGHNESS PARTICLE SCAN AT MICROSCOPE SCALES TO ENSURE COST SAVINGS IN THE MIXING PLANT.
Philipps J
Pixargus GmbH
A novel extruder quality control system, which is equipped with a digital camera capable of scanning large surface pictures on the microscopic scale, is described and the cost savings achievable with this system are indicated. The extruder/camera system, which is called QS-Extruder, is fitted with a special die for determining rheological parameters, such as shear viscosity and shear stress. 3 refs.

FULLERENE-LIKE STRUCTURES AS INTERACTION SITES BETWEEN CARBON BLACK AND RUBBER.
Cataldo F (Trelleborg Wheel Systems SpA)
The effects of ball milling of carbon black and graphite on their surface activity in compounds with natural rubber were investigated by measurements of bound rubber content (solvent extraction), grafted rubber content and surface area (iodine absorption). The results are compared with those for natural rubber filled with extracted fullerene carbon black, and the role of fullerene-like nanostructures in the formation of bound rubber and grafted rubber is discussed. 42 refs.
