Abstract:

AbstractThe removal of indoor air contaminants by reactivity with air filters coated with reagents has been found to be effective for aldehydes, acidic and basic vapours as well as isocyanates Coatings of polymeric amines were used for formaldehyde trapping as well as for the removal of acidic vapours and for the removal of isocyanates. The addition of glycerol as a plasticizer for the coating can also be an effective reagent.

Abstract:

Abstract Polymer melts can be mixed with many monomers, plasticizers, antistatics or foaming additives. Properties of such mixtures can change during blending because of chemical reactions like polymerization or crosslinking. The process may be carried out either in stirred tanks, extruders or in motionless mixers. In this paper we focused on the mixing time and the diffusion time of reagent, plasticizer and polymer thanks to rheological tools, and on the way how rheological properties can be studied during chemical reaction in polymer blending.

Abstract:

It is shown that the use of water-coal fuel mixtures as an energy resource in the production of heat and electric energy can not only significantly expand the resource base of the heat and power industry, but also improve the environmental performance of coal combustion on heat power equipment. One of the main problems of using coalwater fuel is its high viscosity, which complicates the processes of pumping and spraying during combustion. Optimization of the viscosity and other rheological properties of these fuel mixtures is achieved by adding chemical reagents-plasticizers. The experimental

The main factor contributing to the destruction of cement stone under dynamic loading is its low deformation properties.

It is also used in the production of plasticizers, flame retardants, hydraulic fluids, insecticides, pharmaceuticals, gasoline additives and dye intermediates. Phosphoryl trichloride is also used as chlorinating agent, pH regulator, catalyst, solvent in cryoscopy, dopa

AbstractAs of today, oil and gas wells are 6,000 m deep or more. In view of this, increased requirements are imposed on the grouting materials used in wells. Grouting fluids must have rheological properties with low values of dynamic shear stress (τ) and plastic viscosity (η). Reducing the values of τ and η will provide a turbulent flow regime of cementing fluids, which is favourable in terms of complete replacement of the washing fluid with the cementing fluid. In the course of the research, it was found that the Melamine-Formaldehyde Anionic-active Resin superplasticiser is a reagent that ha

BackgroundChemical plastics cause global environmental pollution and can take hundreds of years to be naturally removed from the environment; therefore, eco-friendly alternatives are sought. In that regard, marine algae are considered a promising source for bioplastics. However, macroscopic algae from the Arabian Gulf, despite being produced in massive quantities every year, have never been exploited for this purpose. Moreover, most of the available studies have been primarily based on the extraction of specific components of algae to prepare algal bioplastics, which is laborious and costly an

This versatile reaction operates under ambient conditions, on a gram scale, and accommodates a wide range of alcohols, amines, and anhydrides. The one‐pot process involves a two‐step sequence, starting with the nucleophilic opening of the anhydride, facilitated by either an amine or an alcohol, followed by esterification. TMSCl serves a dual role, acting as a sacrificial reagent to remove in situ water and as a Lewis acid cat
