SDS-986 double-metal composite passivator |
| Brief
SDS-986 double-metal composite passivator is made of inorganic quinqueva-lence antimony, stannic and other auxiliaries. It can reduce the poisoning of nickel and vanadium to catalyst. Its eefct is similar to the antimony passivator ; at the same time, it can reduce the crystal damage casued by vanadium . It has good solubility in the water and high decomposed temp. There are no special equipment for this agent
Adding procedure:
passivator is stored in the tank, the adding pump is plunger pump. the passivator is put into feeding pipe, this pipe must has emptying valve on it.
