High Level Product Silicon Magnesium

Silicon magnesium particles have a nanoparticle size and a high positive charge, which gradually decreases as the pH increases; as the grinding time extends, the particle size of silica magnesium decreases, but its positive charge also significantly decreases. When silica magnesium cationic particles are used alone as a retention aid, they have a certain retention effect, but their dosage is large and the effect is average, and they have poor shear resistance, making them not an ideal retention and filtration aid system. The dual retention system composed of silica magnesium particles and APAM has good retention effectiveness, where the system composed of unground silica magnesium particles/APAM has good shear resistance and pH adaptability. Therefore, the retention system composed of unground silica magnesium particles and APAM is an ideal retention and filtration aid system.

1.A one-time forming mechanism for inorganic silicon-magnesium exterior wall insulation composite panels and production process, which includes insulation composite panel surface layers made from magnesium chloride, magnesium oxide, silicon dioxide, glass fiber cloth, bamboo mat pieces, dolomite filler, and modifiers, as well as the intermediate insulation layers and bottom layers also made from magnesium chloride, magnesium oxide, silicon dioxide, glass fiber cloth, dolomite filler, and modifiers. The surface layer, intermediate insulation layer, and bottom layer of the insulation composite panel are formed through a one-time roller pressing process, changing the traditional manual on-site operations. This allows for mechanized factory production using inorganic silicon-magnesium cement materials, saving labor costs and time, significantly improving project quality and the operability of quality acceptance. The weight is one-half to one-third that of traditional exterior wall insulation materials; the impact strength is over twice that of ordinary composite panels; it resists 40 freeze-thaw cycles without any change, surpassing silicate cement boards; it has good toughness and strong wind resistance, making it the best product for current exterior wall insulation composite panels.
