Silicon carbide particle catcher with silicon dioxide protective film and preparation method of silicon carbide particle catcher
The invention discloses a silicon carbide particle catcher with a silicon dioxide protective film. The silicon carbide particle catcher comprises the following components in parts by weight: 72-78 parts of silicon carbide powder, 12-18 parts of silicon powder, 6-9 parts of silicon oxide powder, 40-52 parts of talcum powder, 20-35 parts of aluminum oxide, 8-15 parts of kaolin, 6-9 parts of stearic acid with the concentration of 5-10%, 1-5 parts of methyl cellulose and 1-5 parts of shell powder. The invention also discloses a preparation method of the silicon combined silicon carbide particle catcher. By adopting the design provided by the invention, a silicon dioxide protective film which wraps the main body material and has relatively high porosity can be formed, so that the strength of the product is improved on the premise of keeping the original filtering performance.
本发明公开了一种具有二氧化硅保护膜的碳化硅颗粒捕捉器，按重量份数包括72～78份的碳化硅粉末，12～18份的硅粉，6～9份的氧化硅粉末，40～52份的滑石粉，20～35份的氧化铝，8～15份的高岭土，6～9份浓度为5％～10％的硬脂酸、1～5份的甲基纤维素和1～5份的果壳粉。本发明还公开了此种硅结合碳化硅颗粒捕捉器的制备方法。采用本发明的设计，能够形成包裹了主体料的具有较高气孔率的二氧化硅保护膜，使得在保持原有的过滤性能的前提下，提高产品的强度。
