The use of maleic anhydride as a compatiblizer between wood particles and bisphenol A-based polyesters resins has been investigated (Han etal., 1991). In this study, the MA was added directly to the composition of woody matrix filler and resin rather than by pre-modification of the wood. It was found that composite properties were improved by addition of MA, probably due to esterification of the wood occurring during the kneading process. The modification of sawdust using maleic anhydride has been performed in order to provide a compatible filler for polyester resins (Marcovich etal., 1996). Modification was performed at room temperature using a solution of maleic anhydride in acetone, in some cases catalysed with sulphuric acid. It was claimed that bonding occurred under these mild conditions from IR spectroscopic evidence only. 

For starch-Bionolle compound production process, we obtain data of product yield and mixing ratios of Bionolle, starch, plasticizer, and water from actual site data provided by Showa Denko. Data of electric power consumption for kneading process are taken from actual site data from Showa Denko. 

For starch-Bionolle compound, Bionolle production from succinic acid and 1,4-butanediol corresponded to approximately one-quarter (one-half excluding disposal) of the total life cycle. Production of succinic acid and 1,4-butanediol account for about 10% (around 20%, excluding disposal) of the total life cycle. In addition, the starch kneading process accounts for about 5% of the total life cycle. Sea transport for starch account for around 3% of the total life cycle. 

The material obtained from the kneading process should be, after drying and blending, compressed to tablets. The compressing capabilities and the tablet characteristics (content uniformity, thickness, hardness, friability, weight variances, and disintegration time) should meet the finished product specification for the compressed tablets. 

This principle of mixing by means of suspended wheels was not introduced until the end of the nineteenth century before then the kneading process in edge runners was the most dangerous operation in the manufacture of blackpowder. Wooden... 

In this study, the foregoing methodology of dimensional analysis was applied to a kneading process of drug-cyclodextrin complexation. Aoustin kneader with dual Z blades was instrumented for torque measurements and multiple runs were made at two scales (2.5 and 5L).

Formulation of poly (vinyl chloride) into sheet goods is often beset with color problems. The kneading process takes place in the presence of dibutyltin maleate to initiate cross-linking reactions. The presence of AMS dimer in the kneading process leads to less yellowing and better thermal stability for the PVC sheet.485... 

The wear situation is likely to be aggravated should hard additives of a coarser grain fraction be embedded in a softer matrix, such as clay, as the result of an upstream kneading process. This may lead to grain sliding wear (besides a two-body and even a proper three-body abrasive wear), which could, in the absence of an intermediate lubricating medium, have drastic consequences. Similarly, lack of an intermediate medium will favour any likely adhesive wear.

To solve these problems, a kneading process of previously adding a surfactant to a resin has been employed. According to the kneading process, the surfactant bleeds out from the inside to the surface of the resulting molded article to form a surfactant layer, and thereby exhibits performance such as antistatic properties and antifogging properties. These properties may sustain to some extent even when the surfactant at surface is wiped off, because the surfactant in the inside of the resin bleeds out again to thereby recover the properties. 

Direct observation of boehmite paste texture by cryomicroscopy is shown to be a very promising approach for the understanding of phenomena occuring in a continuous kneading process. This technique makes possible the characterization of a state of boehmite peptization in relation with the operating parameters. The porosity of the final extrudate can be related to the peptization state and could be tailored through a better control of this latter. Present studies are carried out to achieve a more quantitative description of peptized pastes. 

The aroma is influenced by the recipe but also by the fermentation, e. g., the Strecker aldehydes increase and those from lipid peroxidation decrease if the dough matures at lower temperatures (Table 15.60). An extension of the kneading process... 

The molecular weight, MW, of PES samples subjected to different kneading process are also reported in Table 4. As shown, MW increases with time at the same speed of the roller (15 rpm), and it also increases with the speed of the roller after the same duration.
