我厂铸钢车间是采用水玻璃砂来生产车辆用铸钢件的。在实际生产中发生粘模问题,过去曾采用煤油加桐油以及用硝基磁漆来徐刷模型防止水玻璃砂的粘模和对模型的腐蚀,但效果都不理想。为此我们近来研制了LF型水玻璃砂快干脱模剂,经使用检验,获得良好效果,深受生产工人的欢迎。一 LF型脱模剂的防粘砂效果为了验证LF型脱模剂的防粘砂效果,我们分别在平板润湿实验及在金属型、本型、塑料型 Our steel plant is the use of sodium silicate to produce steel castings. Adhesion problems occur in actual production. In the past, kerosene plus tung oil and nitrocellulose lacquer were used to prevent sticking of water glass sand and corrosion of the model, but the results were unsatisfactory. To this end we have recently developed LF-type sodium silicate quick-drying release agent, the use of testing, access to good results, welcomed by the production workers. A LF release agent anti-stick sand effect In order to verify the LF release agent anti-sticking sand effect, respectively, in the plate wetting experiments and in the metal, this type, plastic type
