The Utilization of Informatics in Viscosimetrics Properties Correlation of Elastomers, Determined with Different Apparatus
ABSTRACT. The work presents a product program of rheo - viscosimetric values estimation of the following parameters: plasticity, prevulcanisation and vulcanization time, obtained with the following apparatus: Mooney plastometer, Monsanto rheometer and Brabender plasticorder, on the mathematical base, processed through statistical regression. To realize the correlation of the rheo-viscosimetric results obtained on different apparatus it was elaborated a series of receptures with different degrees of plasticity and also different times of prevulcanisation and optimal times of vulcanization. It was crated data base cumulated for each rheo-viscosimetric parameter using a data base program (FoxPro).
KEY WORDS: product program, parameters, data base program
Manufacturing Technology of Antistatic and Conductive Protective Footwear
ABSTRACT. The work presents the technologies of some special types of footwear, specific of some important domains, with high level of dangerousness. The protective footwear is different in comparison with usual footwear, because must answer to the exigencies imposed by environment conditions of work, to assure the workers legs protection during activities which involves risks factors.
KEY WORDS: special type of footwear, technologies, protective footwear
