Combination of inhibitors

Posted on

Although the combination of inhibitors is far less than the combination of collectors , it is still quite a lot. The combination types are:
1. Sulfide ore containing cyanide inhibitor combination
Such combinations are as follows:
Lime and cyanide combination;
Lime in combination with sulfur dioxide and zinc cyanide complexes;
Combination of zinc sulfate and cyanide;
a combination of zinc oxide and cyanide;
Calcium salts are combined with cyanide and zinc oxide.
  Second, sulfide ore non-cyanide inhibitor combination
Such combinations are as follows:
Lime combined with sodium sulfide;
Lime combined with sulfurous acid or with sulfur dioxide;
Lime in combination with sodium sulfide and zinc sulfate;
Lime in combination with sodium sulfide and sulfurous acid;
Lime combined with sodium sulfide, sulfur dioxide and zinc sulfate;
A combination of lime and potassium permanganate;
Lime combined with zinc sulfate;
Sodium carbonate combined with zinc sulfate;
Sodium carbonate in combination with zinc sulfate and sodium sulfide;
Combination of zinc sulfate and sodium sulfide;
Combination of zinc sulfate and sulfurous acid (sodium);
Ferrous sulfate zinc sulfate and combinations thereof;
Sodium sulfide combined with ferrous sulfate;
Sodium sulfide in combination with sulfurous acid;
Sodium thiosulfate combined with sulfurous acid;
Sodium thiosulfate combined with ferrous sulfate;
Sodium thiosulfate combined with zinc sulfate or aluminum sulfate;
Sodium thiosulfate combined with zinc sulfate and high-sulfur sulfate;
Weight of chromium in combination with potassium silicate;
Dichromate in combination with sulfite;
Dichromate in combination with zinc sulfate;
Sodium sulfide is combined with lime, zinc sulfate and water glass.
Third, non-sulfurized mineral inorganic inhibitor combination
Such combinations are as follows:
Sodium silicate combined with ferrous sulfate;
Sodium silicate and magnesium oxide in combination;
Sodium silicate combined with sodium carbonate;
Some sodium silicate with weakly basic polyvalent metal cations in combination.
Fourth, the combination of organic inhibitors such as:
Wheat dextrin combined with white gum and wood pulp;
Carboxymethyl cellulose combined with starch and dextrin;
Carboxymethyl cellulose combined with tannin;
Lignosulfonate in combination with polyacrylamide;
Carboxymethylcellulose is combined with thiourea.
   5. Combinations of organic and inorganic inhibitors such as:
Water glass combined with carboxymethyl cellulose;
Water glass in combination with carboxymethyl cellulose and sulfurous acid;
Water glass combined with chlorinated lignin;
Water glass combined with carboxymethyl cellulose and potassium dichromate; [next]
Combination of carboxymethyl cellulose and zinc sulfate;
Carboxymethyl cellulose in combination with water glass and sodium sulfide;
Carboxymethyl cellulose combined with lime;
Combination of starch and dichromate;
Combination of starch and water glass;
Combination of starch and sodium sulfide;
Starch in combination with sulfur dioxide and dichromate;
Starch combined with sulfurous acid and sulfuric acid;
Dextrin combined with white gum, wood pulp, zinc sulfate;
Gurgain combined with sulfur dioxide;
Crude sulfonate (S808) combined with water glass;
Sodium humate combined with water glass;
Sodium citrate is combined with lime.
Table 1, Table 2, and Table 3 are examples of the effects of the combined use of different types of inhibitors.

CNC Rapid Prototyping is the first step to test the product feasibility. Prototype(model) is the first sample of production, the designer usually uses this method to get a prototype to observe his new product`s advantages or disadvantages to avoid wasting too much time, money and manpower between the processing of rapid prototyping. Rapid Prototyping can be applied to many fields.
