Review of common rubber factory problems and published causes and solutions--part I.- A+ w, }" L' h5 s

Rubber is different from other engineering materials in that it is commonly subject to many unique processing problems that are not normally encountered with the processing of other non-rubber materials. In addition, the literature is somewhat limited in discussing some of these problems and their causes. , e3 X/ `/ P& w! c) q( \% l

- S, x4 ~; E& w3 r+ f. A4 y- ?It is very important to realize that any change (or changes) applied to a rubber compound or process is certain to also affect, for better or for worse, many other compound properties (either uncured or cured). Therefore, any change that is made to a rubber compound or process should be thoroughly researched beforehand. These changes should first be tried out on a laboratory scale, determining how all the processing and cured physical properties are affected, including all compound specification properties. Also, there should be a limited factory trial performed to determine more clearly what affects this change (or changes) might have on the process and the rubber product. In addition, limited product field studies should also be performed to assure that there are no hidden long-term problems associated with these changes. All appropriate health and safety precautions should be followed. Only those with advanced scientific training and rubber compounding experience should implement such changes. |
