Pneumatic Brake System Qhuav Siv 4A Molecular Sieve Adsorbents

4A Molecular Sieve, yog alkali alumina silicate. Nws yog daim ntawv sodium ntawm hom A siv lead ua qauv. Nws muaj qhov zoo ntawm qhov pore qhib ntawm li 4 angstroms (0.4nm). Nws yuav adsorb feem ntau cov molecules nrog lub kinetic txoj kab uas hla ntawm tsawg dua 4 angstroms thiab tsis suav cov loj. 4A Molecular Sieve, qhov pore loj faib yog qhov sib xws, muaj cov khoom adsorption zoo heev thiab cov roj adhesion zoo, thiab muaj qee yam tsis zoo alkalinity. Nws yog non-toxic, nyab xeeb thiab txhim khu kev qha rau tib neeg lub cev, thiab tsis muaj kev cuam tshuam rau ecosystem.
