Hebei Messi Biology Co., Ltd. stated that basic magnesium carbonate was surface modified with stearic acid and added to a mixture of low-density polyethylene (LDPE) and ethylene-vinyl acetate (EVA) to prepare flame-retardant composite materials. The effect of basic magnesium carbonate on the flame retardancy and mechanical properties of LDPE/EVA was studied. Scanning electron microscopy (SEM)

Hebei Messi Biology Co., Ltd. stated that this article describes the application of redox method for iron removal in the preparation of magnesium carbonate, and examines the effects of reaction time, reducing agent, oxidizing agent, and complexing agent on the iron removal effect. Experiments show that under optimal reaction conditions, the iron content drops to

Hebei Messi Biology Co., Ltd. stated that carbonate rock is a widely distributed rock type on the earth. Its weathered products will enter the soil and sediments in the area and become the main component thereof. In the carbonate mineral-heavy metal-water solid-liquid system, carbonate minerals can interact with metal ions such as Cu, Pb, Zn,

Hebei Messi Biology Co., Ltd. stated that it uses the sol-gel method to prepare nano-magnesium oxide using magnesite, hydrochloric acid and urea as raw materials, and adding the gelling agent polyethylene glycol. The effects of calcination temperature, gelling agent molecular weight, dispersing agent and their dosage on the experiment were investigated. The results show that
