“…Some studies also consider the ability of cool pigments to reduce surface temperature [12,13], the properties of organic pigments [14][15][16] and spinel pigments [17][18][19], color changes of thermochromic pigments under temperature [20][21][22], or color fading [23]. However, there are few studies testing the impact of pigments on the functional and processing properties of waterborne emulsion paints or coatings [24][25][26]. Mentioned studies provide little research on the overall impact that additives can have on the product.…”

The purpose of this research was to evaluate the impact of selected pigments on the performance of waterborne emulsion paint. Each pigment was incorporated into the paint at 5% w/w. Density and viscosity measurements as well as the rub-out test were used to test the wet state properties of the colored paint. Wet-scrub, adhesion-to-substrate, water-uptake, vapor-permeability, UV-aging, and other tests were conducted to evaluate effects of the pigments on the dried paint. Bohemian green earth pigment was found to have the most positive effect, as it improved the water resistance of the paint without changing its rheological properties. Therefore, this pigment was selected for further studies, in which the pigment was included as part of the paint formula rather than as a post-additive. The results were satisfactory, confirming the compatibility of the pigment with the formula. However, a slight change in the rheological profile of the paint was observed during tests on a rotational rheometer. This research shows the need for intensive quality control measures while testing alternative formulations, to both enable early detection of negative effects and identify possible improvements.

“…However, during marble mining and processing, as much as 60% of the total product generated is solid waste material, including waste, waste powder, and waste mud. [1][2][3] These solid waste materials occupy large volumes in landfills, causing serious environmental pollution and threats to public health. [4][5][6][7] Artificial marble wastes (AMWs), which are by-products of artificial marble sawing or polishing, are one of the most common types.…”

The treatment of artificial marble wastes (AMWs) is a difficult aspect of the artificial marble industry and has enormous impacts on the environment. Herein, a series of polybutylene terephthalate (PBT)/AMWs composites were prepared by in situ polymerization. The effects of AMWs content (1–10 wt%) on the thermal stability, crystallization rate, and impact strength of the PBT/AMWs composites were investigated in detail. The results showed that the composites containing 10 wt% of AMWs exhibited the best performance. Due to the high thermal resistance and uniform distribution of the AMWs particles, the heat deflection temperature reached 67.40°C with optimal thermal stability. Additionally, under heterogeneous nucleation, the crystallization rate was also the highest, and impact strength reached 17.29 kJ/m2 due to the partial core-shell structure and hardened matrix effects of the AMWs particles.

“…The high concentration of Zn ions with chromophore properties in the spent electrolytes of Zn plating indicates the possibility of their use for the production of pigments and pigment pastes by the example of other wastes. [20][21][22][23] This direction is especially relevant for some countries where the production of pigments is absent and they are completely purchased abroad.…”

BACKGROUND The volumes of discharged spent plating electrolytes comprise ≈2–3% of the total amount of wastewater from galvanic production. However, the concentration of heavy metal ions they contain is 100–150‐fold higher than in rinsing waters. The periodic nature of such discharges leads to a disruption in the operation of treatment facilities. At the same time, heavy metals could be separated as pigments. RESULTS The article presents the results of studies of the effect of brighteners included in the composition of spent zinc (Zn) plating electrolytes on the composition and structure of the resulting white pigments. The results confirmed the possibility of obtaining white pigments from spent Zn plating electrolytes. It was found that during the deposition of Zn(II) ions from the spent ammonium chloride (NH4Cl) Zn plating electrolytes with sodium phosphate, zinc phosphate predominantly is formed. It was found that the presence of brighteners in the spent NH4Cl Zn plating electrolytes practically did not affect the pH and the degree of deposition of Zn (II) ions, as well as the whiteness of the resulting pigments. CONCLUSION The presence of iron (Fe) ions in the spent zinc plating electrolytes leads to a decrease in the whiteness of the resulting precipitates; however, pigments of the required whiteness can be obtained with contents of Fe(III) of ≤170 mg L−1 and Fe(II) ≤1000 mg L−1. © 2021 Society of Chemical Industry (SCI).
