硅藻土是一种分布较广的沉积岩,易磨成粉末,有强烈的吸水性。硅藻土能够杀虫,原因在其粉末的每一细微颗粒都带有非常锐利的边缘,与害虫接触时,可刺透害虫体表,甚至进入害虫体内,不仅能引起害虫呼吸、消化、生殖、运动等系统出现紊乱,而且能吸收3-4倍于自身重量的水分,致使害虫体液锐减,在失去10%以上的体液后死亡。依据硅藻土的杀虫机理,以硅藻土作主要原料,配入其它辅料生产杀虫剂有两种途径。一是以刺杀作用为主。将硅藻土粉碎,适当雾化后可成为能刺杀害
Diatomaceous earth is a widely distributed sedimentary rock, easy to ground into a powder, has a strong water absorption. Diatomaceous earth can kill insects because each tiny particle of the powder has a very sharp edge. When in contact with a pest, it can penetrate the surface of the pest and even enter the body of the pest, which can not only cause the pest to breathe, digest and reproduce , Exercise and other systems appear disorder, but also to absorb 3-4 times its own weight of water, resulting in sharp drop in body fluids of pests, after losing more than 10% of body fluids and death. According to the killing mechanism of diatomite, diatomaceous earth as the main raw material, with other accessories into the production of pesticides in two ways. First, the main role to assassinate. Diatomaceous earth crushed, after appropriate atomization can become a sting kill
