Chopped carbon fiber pre-dispersion method of carbon fiber anti-radiation concrete
The invention relates to a short carbon fiber pre-dispersion method of carbon fiber radiation protection concrete, which comprises the following steps: adding a dispersing agent into water, and stirring for the first time to form a dispersion liquid; adding short carbon fibers into the dispersion liquid, and performing secondary stirring to form a carbon fiber dispersion liquid; the mixing amount of the dispersing agent is related to the mixing amount of the carbon fiber, and when the mass ratio of the carbon fiber to the water is less than 1%, the mixing amount of the dispersing agent is 0.25-0.35% of the mass of the water; when the mass ratio of the carbon fiber to the water is greater than or equal to 1%, the mixing amount of the dispersing agent is 0.002 * the mass of the water + 0.1 * the mass of the carbon fiber. Compared with the prior art, under the condition that the mixing amount of the dispersing agent is as low as possible, the dispersion degree of the short carbon fibers is improved, and the influence of the dispersing agent on the performance of the carbon fiber radiation protection concrete is reduced as much as possible. According to the method, the surface of the short carbon fiber is not abraded, negative effects on the short carbon fiber are avoided, and the excellent performance of the short carbon fiber is guaranteed to the maximum extent.
本发明涉及一种碳纤维防辐射混凝土的短切碳纤维预分散方法，包括以下步骤：将分散剂加入水中一次搅拌，形成分散液；将短切碳纤维加入分散液中二次搅拌，形成碳纤维分散液；所述分散剂的掺量与碳纤维的掺量有关，当碳纤维占水质量比＜1％时，分散剂的掺量为水质量的0.25％‑0.35％；当碳纤维占水质量比≥1％时，分散剂的掺量＝0.002×水的质量+0.1×碳纤维的质量。与现有技术相比，本发明在分散剂掺量尽可能低的情况下，提高了短切碳纤维的分散程度，并尽量减少分散剂对碳纤维防辐射混凝土自身性能的影响。本发明对短切碳纤维的表面无磨损，不会对短切碳纤维造成负面影响，最大程度的保证了短切碳纤维的自身优异性能。
