Gas rigid gelled material' Lime. _ grouting material in guangzhou - the latest price The cement slurry injection

grouting material in guangzhou guangzhou guangzhou grouting grouting material manufacturer material price lime is used for a long time on the building, a kind of widely used gas rigid gelled material. Due to its wide raw material sources, simple production process, low cost advantages, is widely used in construction field. Lime production: production lime raw materials based on calcium carbonate ( CaCO3） As the main component of natural minerals, such as limestone, chalk, dolomitic limestone, etc. Will get the lime (raw material calcined at high temperature can be The massive quicklime) 。 Its main component is calcium oxide. In the process of the reaction due to the raw material also contains a certain amount of magnesium carbonate, decompose at high temperature for the magnesium oxide and carbon dioxide, so products will be aerobic no JiGuan slurry magnesium exist. In general, under the condition of normal temperature and burning time of calcined lime with a porous, small, small volume density, and particle characteristics such as fast reaction with water, the lime, called normalizing lime. And the actual production process due to the calcination temperature too low or too high will produce subcooling or limestone. Such as calcination temperature is low, not only make the calcining time is too long, and the center of the lime piece is still not fully decomposition, lime contains no decomposition of calcium carbonate, now called the subcooling lime, it will reduce the utilization rate of lime, but subcooling lime when use won't harm. & N good grouting material manufacturer telephone BSP; Such as calcination temperature is exorbitant, after the calcination of lime compact structure, small porosity, bulk density, coarse grains, vulnerable to glass material package, so it is with water chemical reaction speed is very slow, called it a burned lime. Normalizing lime hydration, and began to condense sclerosis, and far hydrated lime began, before and after the hydration products of the reaction volume expansion, caused the structure to produce crack or split have hardened, the phenomenon such as uplift, the use of lime is very bad.
