摘要/Abstract

摘要： 氟石膏的强酸性与较低水化活性限制了其在抹灰石膏领域的应用,为解决这一难题,本文选用CaO、Ca(OH)₂为中和剂,Na₂C₂O₄、Na₂SO₄、K₂SO₄、K₂SiO₃、半水石膏为激发剂,对氟石膏水化活性进行改性,探究中和剂与激发剂种类、掺量对改性效果的影响。结果表明:3%(质量分数)的中和剂可以将氟石膏pH值提高至9左右,并使氟石膏中游离氟含量维持在0.02%(质量分数)左右,基于成本考虑,选择价格更低的CaO为中和剂;K₂SO₄、Na₂SO₄和半水石膏作为激发剂均有较好的激发效果,其中Na₂SO₄激发效果最好,经1.0%(质量分数)Na₂SO₄激发制备的抹灰石膏初凝时间为119 min,终凝时间为252 min,抗压强度为10.30 MPa,抗折强度为3.85 MPa,各项指标均达到《抹灰石膏》(GB/T 28627—2023)的要求。

Abstract: The high acidity and low hydration activity of fluorgypsum restrict its application in the field of plastering gypsum. In order to solve this problem and promote the large-scale application of fluorgypsum in plastering gypsum, CaO and Ca(OH)₂ were selected as neutralizer while Na₂C₂O₄, Na₂SO₄, K₂SO₄, K₂SiO₃ and gypsum hemihydrate were selected as activator, to modify fluorgypsum. The effects of type and dosage of activator and neutralizer on modification effect were investigated. The results show that 3%(mass fraction) neutralizer can improve the pH value of fluorgypsum to around 9 and keep its free fluorine content around 0.02% (mass fraction). Considering the cost, the cheaper CaO is choose as neutralizer. In addition, K₂SO₄, Na₂SO₄ and gypsum hemihydrate as activator have good excitation effect, among which Na₂SO₄ has the best excitation effect. Plastering gypsum excited by 1.0% (mass fraction) Na₂SO₄ is prepared, with initial setting time of 119 min and final setting time of 252 min. Moreover, the compressive strength is 10.30 MPa while the flexural strength is 3.85 MPa. It should be noted that all indicators reach the requirements of “Plastering gypsum”(GB/T 28627—2023).

Key words: fluorgypsum, neutralizer, activator, setting time, compressive strength, flexural strength, hydration rate
