Specification:
First, an overview
YH30-PL phosphate free spray degreasing agent. Its main characteristics are: environmental protection and energy saving. A variety of surfactants and phosphate free additives can be used to remove all kinds of oil quickly at low ambient temperature. The bath liquid is stable and the process control is simple and so on. As the degreasing agent is low in concentration and low in alkalinity, the degreasing workpiece can be washed in a short time only with a short time, and the degreasing agent can enter the next process, and the pollution of water is low.
This product is suitable for spraying, soaking operation line. When the room temperature is higher than S C, the degreasing need not be heated. Therefore, it has good environmental protection and energy saving performance.

Tank liquid preparation: in the tank, the 2/3 volume water is filled, the amount of YH30-PL degreasing agent is added to the specified volume, the mixing is uniform, then the test and adjustment to the process range, can be put into use. In the process of treatment, the free alkalinity is reduced and the degreasing ability is reduced. At this time, some degreasing agents must be supplemented to the range of free alkalinity, and the bath liquid can be used for a long time.
Four, packaging and storage and transportation
This product 30kg woven bag packaging, storage and transportation when moisture-proof, thermal protection, storage period of three years.
Five. Security measures
Workers should wear rubber gloves. If the liquid is rubbed on the skin or eyes, rinse immediately with plenty of water and send it to the doctor if necessary.
