Tea tea in the additive silica is what role do harm?
The national standard prescribed food additives with silica anti caking agent for three, precipitated silica, fumed silica, silica gel three kinds. The three kinds of food additives for synthetic silica with high purity silica white powder. Two synthetic silica has high porosity, large surface area, strong adsorption. Very stable chemical properties, non-toxic, tasteless, after eating inside the human body without rational disease. As a food additive anti caking agent with silica, can keep the medicinal powder drying and mobility, a long time to prevent the phenomenon of agglomeration.
By eating into the body of the additive with silica, alkali, acid and acid environment, cavity environment of weak acid environment on the intestine are not decomposed, does not absorb, finally with the feces discharged together. It is worth noting that the higher value of free silica content in the air (respirable silica dust: the standard of respirable dust collection means the dust in the air dynamics diameter below 7.07 m, and the aerodynamic diameter of 5 mu m dust collection efficiency of 50%. in respirable dust free silica content of more than 10% people called respirable silica dust in the air. The workshop 10%~50% containing free silica respirable silica dust the maximum allowable concentration of 1mg/m3. in the air of workplace with more than 50%~80% of free silica respirable silica dust the maximum allowable concentration of 0.5mg/m3. in the air of workplace containing more than 80% free silica respirable silica dust maximum allowable concentration For 0.3mg/m3.) in this type of work environment, chronic exposure (a few weeks with a weak constitution and a few years of strong constitution) can lead to silicosis
