Abstract
A kind of method for oxidation for preparing lead oxide powder, it is under normal temperature condition, is catalyzer with water or hydrogen peroxide, the finely-divided metal lead powder is under the moisture state grinds, and is oxidized to PbO gradually.Because oxidation under moisture state so can not produce steam, avoids lead powder to fly upward, and has prevented pollution.Again owing to do not need F.D. and dust collecting system etc., thereby simplified technology, saved the energy, reduced cost, and plumbous oxidation area is big, speed of response is fast, oxidisability is high.
Description
The present invention relates to a kind of method for oxidation for preparing lead oxide powder.
At present, be the method for feedstock production lead oxide powder in the world with powdered metallic lead, can be divided into three kinds substantially.A kind of is Tianjin (Shimadzu) formula, the metallic lead oxidation style of promptly dry grinding.Because this method is carried out in air, collect lead oxide powder by cyclone scrubber, when air-flow provides oxygen, taken away lead powder again, cause waste.Another kind is Ba Dun (Barton) formula, i.e. the plumbous oxidation style of molten metal.Plumbous liquid carries out in reactor because this method is a fused, and technology is comparatively complicated.Also having a kind of is to utilize special device, and lead is oxidized to smoke-like, and sedimentation forms then, and this method energy consumption is big, cost is high and fail practicality.Above-mentioned prior art is at " Journal of Power Sources " .23(1988) reflection is arranged in 8791 " the INNOVATONS AND DEVELOPMENTS IN OXIDE PRODUCTION FOR LEAD/ACID BATTERIES " literary composition.
The objective of the invention is to overcome the deficiency of prior art, is raw material with the finely-divided metal lead powder, carries out abrasive method under the state of moistening and aerobic existence, makes powdered metallic lead be oxidized to plumbous oxide compound-PbO gradually.
Mechanism of the present invention is such, when adding entry in metallic lead (Pb) powder and grind as catalyzer, just can make leady oxide become lead oxide powder (PbO) gradually.Obviously, the prerequisite here is to add water, and prerequisite is to grind, and Neither of the two can be dispensed.Its chemical equation is:
The catalyzer that is adopted among the present invention can also be a hydrogen peroxide.Its chemical equation is:
The present invention is owing to be to grind gradually under moisture state that oxidation forms, so, can not produce steam like this, avoid lead powder to fly upward, thereby, improved envrionment conditions, prevented pollution.Again owing to do not need F.D. and dust collecting system etc., thereby, simplified technology, saved the energy, reduced cost, and plumbous oxidation area is big, speed of response is fast, the oxidisability height.
Realization of the present invention can illustrate with following several examples:
Example 1:
80 mesh sieve powdered metallic leads: 70 parts
Clear water: 20 parts
Under normal temperature condition, in proportion lead powder is poured into wetting back the grinding 30 minutes to 1 hour in the water, be oxidized to PbO gradually, its oxidisability can reach more than 80%.
Example 2:
40 mesh sieve powdered metallic leads: 70 parts
Hydrogen peroxide: 10 parts
Under normal temperature condition, in proportion lead powder is poured in the hydrogen peroxide and ground 30 minutes to 1 hour, be oxidized to PbO gradually, its oxidisability can reach more than 80%.
Claims (1)
- A kind of method for oxidation for preparing lead oxide powder, it is characterized in that: lead is the finely-divided metal lead powder, and catalyzer is water or hydrogen peroxide, under normal temperature condition, powdered metallic lead poured into it is in behind the moisture state ground 30 minutes to 1 hour, and be oxidized to lead oxide powder gradually.
