The Additive LS-914A for Two Acids is a product with excellent performance, convenient application, and environmental friendliness, presenting as a light brownish-yellow liquid in appearance. This additive has numerous outstanding characteristics and functions. It can effectively reduce costs by adjusting the concentration of the bath solution to minimize the carry-out of the chemical solution. It is extremely easy to use. Just add it at a ratio of 8% - 12% to the common two-acid polishing bath, and it can be put into use.The operation process is simple. According to the differences in materials and the pre-treatment effects such as the mechanical polishing of workpieces, the addition amount of the polishing agent can be flexibly adjusted to obtain a satisfactory chemical polishing effect. Moreover, it can ensure the stability of the brightness of the polishing effect and the performance of the solution, and has a long service life.It is particularly worth mentioning that the Additive LS-914A for Two Acids does not contain heavy metals and will not produce yellow fumes during the production process, which is very environmentally friendly. It can greatly improve the working environment and at the same time enhance the product quality.In terms of operating conditions, there are clear standards and ranges for its preparation parameters: the ratio of phosphoric acid to sulfuric acid is 4 - 12:1, and the ratio of phosphorus to sulfur needs to be adjusted according to the materials during actual operation; the standard addition amount of DX-914A is 10%, which can vary within the range of 8% - 15%; the standard temperature is 78°C, with a range of 70 - 90°C; the standard time is 60 seconds, with a range of 25 - 180 seconds.
