Bonding Dust with Environmentally Safe Compositions on Open Dust-Forming Surfaces in Coal Producing Enterprises
In most current physical models of dust formation, the changes in the interaction power of dust particles are not considered when modifying their surface with chemical substances. Such approach significantly changes the real scientific picture of experiments as it contradicts with empirical facts and doesn’t allow describing the actions of agents with different nature for dust bonding.
In article the dependence of dust bonding features from the level of polarity and molecular weight of plastic binders, the presence of individual functional groups of polymers and SAA, the diameter of salt cations is established; assessment of environmental influence of dust bonding agents is given in respect to the processes of biological recultivation; a complex indicator for selecting dust bonding agents is given, that represents a linear combination of individual indices of adhesive and environmental action of agents and indices of economic assessment of their application; a new scientific and methodological approach to compiling compositions of dust bonding agents is developed.
Disclaimer/Regarding indexing issue:
We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information.
