Description

一种微生物修复剂生产线及其生产工艺 技术领域
本发明涉及一种生产线及其生产工艺，尤其涉及一种用于混凝土裂缝自修复的微生物修复剂生产线及其生产工艺。
背景技术
混凝土因其本身具有抗压强度高、耐久性好、原材料易得、价格低廉等优点，已成为世界上使用量最大、应用范围最广的建筑材料。然而，由于混凝土材料自身脆性大、抗拉强度低和收缩变形大等缺点，在其服役过程中会不可避免的产生裂缝，大大影响了建筑的美观性与功能性。同时，裂缝的出现会影响混凝土结构的防水性、承载力和使用安全性，裂缝的产生还会促使钢筋锈蚀、碱集料反应及碳化速度的加快，从而引起混凝土结构耐久性的下降并缩短其使用寿命。
微生物自修复混凝土是将满足要求的微生物修复剂通过一定的方式加入到混凝土中，当混凝土产生裂缝后，自然环境中的空气和水等进入到裂缝中，激活处于休眠状态的微生物，通过微生物自身的矿化作用诱导生成与水泥基材料相容性良好的碳酸钙，有效的填充在裂缝中，阻断混凝土内部与外界环境的物质交换，以达到混凝土裂缝自修复的目的，从而延长混凝土使用寿命，提高其耐久性。
由于混凝土内部高碱性和不断密实的孔隙结构的影响，即便是耐碱性强的芽孢也很难长时间存活，这就降低了混凝土后期裂缝的自修复效果。为此，需要对微生物芽孢进行负载保护，制备核-壳结构的微生物修复剂。然而，常用的糖衣包裹技术采用半自动化和手工操作，生产效率低下，只能适用于少量微生物修复剂制备，无法实现规模化、自动化生产，不利于微生物修复剂的批量化制备与使用。
