Abstract: In this study, shell powder was modified by sodium stearate surface modifier for improving the compatibility of SP with polymer materials. The surface modifiers influence on the physical and chemical properties of SP were studied by scanning electron microscope (SEM), fourier infrared spectrum (FT-IR), surface contact angle meter, XRD diffraction analysis meter and other modern instruments and analysis method. The results showed that the surface modifier was successfully coupled to the shell powder surface. After surface modifier modification, the interfacial compatibility of the shell powder with polymer materials was effectively improved. The contact angle of shell powder surface increased from 73.5 ° to 110.8 ° , along with the dosage of sodium stearate surface modifier was 4.0%. All results suggested that modified shell powder is promising for using as a reinforcement filler in polymer materials.

Abstract: Based on the removal of SO₂ as the research background, this paper focuses on the research of mono-component experiment and orthogonal experiment of compound sulfur-fixing agent composed of shell powder and red mud (at the mass ratio of 8:2) at the temperature of 1000°C and Ca/S was 2.0, by adding manganese dioxide, fly ash, magnesium oxide and potassium carbonate as the sulfur-fixing additive. The experimental results showed that the sulfur fixation capacity of desulfurizer is increased to different extents and the optimal ratio to additive is obtained after addition of the additive.

Abstract: The aim of this study was to put forward a new method to improve the ballistic impact performance of unidirectional plate (UD plate) by adding shell powder into matrix. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR) spectra revealed that modified shell powder was dispersed uniformly in the matrix. The results of ballistic tests and temperature adaptation tests demonstrated that the bulletproof property of modified UD plate was improved about 20%. The heat-resistant temperature was increased approximately 5°C.
