在模拟人体温度 37℃条件下 ,进行多孔纤维矿物粉尘与氨基酸作用的实验研究。在 72h内溶解过程中pH值和电导率的变化结果表明 ,多孔纤维矿物在氨基酸中发生的溶解作用与酸的性质有关 ,酸性氨基酸对矿物的溶解能力最强 ,中性次之 ,碱性最弱。其溶解过程在前 8h以内较强 ,以后趋于平缓 ,纤维矿物在氨基酸中的溶解程度从小到大为 :斜发沸石—坡缕石、海泡石—蛇纹石 ,说明斜发沸石有较强的耐蚀能力 ,其生物持久性较高 ,而蛇纹石石棉则表现为相对低的耐蚀性。
The experimental study on the effect of porous fiber mineral dust and amino acids was carried out at a simulated human body temperature of 37°C. The results of pH and conductivity changes during dissolution within 72 h indicate that the dissolution of porous fiber minerals in amino acids is related to the nature of the acid. Acidic amino acids have the greatest ability to dissolve minerals, followed by neutrality, and alkaline. weak. The dissolution process is stronger within the first 8 hours, and then tends to be gentle. The degree of dissolution of fiber minerals in amino acids is small to large: clinoptilolite-pyrochlorite, sepiolite-serpentine, indicating that clinoptilolite is more Strong anti-corrosion ability, its biological durability is higher, and serpentine asbestos shows a relatively low corrosion resistance.
