Modified straw fiber preparation method, straw fiber, concrete and preparation method
The invention relates to a modified straw fiber preparation method, straw fiber, concrete and a preparation method, straw is pretreated through enzyme, an enzyme solution comprises at least one of a cellulase solution and a pectinase solution, and the pH value of the enzyme solution is 6.5-8.5; putting the straws into a prepared enzyme solution to be soaked for 4-10 hours, and controlling the temperature of the enzyme solution to be 25-55 DEG C; after soaking is completed, the straw is separated from the enzyme solution and cleaned for multiple times; after cleaning is completed, water in the straw is naturally aired or dried, modified straw fibers are obtained, and the obtained modified straw fibers are used for preparing concrete. On one hand, the invention provides a mode different from an existing straw pretreatment mode, the problem that the concrete is low in strength due to the fact that the straw is directly applied to the concrete is solved, and after the modified straw fiber obtained through pretreatment is applied, the strength of the concrete is improved compared with an existing pretreatment mode.
本发明涉及一种改性秸秆纤维制备方法、秸秆纤维、混凝土及制备方法，通过酶对秸秆进行预处理，酶溶液包括纤维素酶溶液和果胶酶溶液中的至少一种，酶溶液的pH值在6.5‑8.5；将秸秆投入配置好的酶溶液中浸泡4‑10小时，酶溶液的温度控制在25‑55℃；浸泡完成后将秸秆从酶溶液中分离出并清洗若干次；清洗完成后将秸秆中水分通过自然晾晒或烘干，得到改性秸秆纤维，将得到的改性秸秆纤维用于混凝土的制备。本发明一方面提供了一种不同于现有的秸秆预处理方式，解决了秸秆直接应用于混凝土存在的混凝土强度低的问题，通过预处理得到的改性秸秆纤维应用后相比与现有的预处理方式处理增加了混凝土的强度。
