361 results about "Thiocarbamate" patented technology

Thiocarbamates are a family of organosulfur compounds. As the name suggests, they are sulphur analogues of carbamates. There are two isomeric forms of thiocarbamate esters: O-thiocarbamates, ROC(=S)NR₂, and S-thiocarbamates, RSC(=O)NR₂.

Method for using cyaniding barren solution to float, reclaim and cyaniding copper plumbum and zinc in tailings

A method that cyanide barren solution is used for recovering the copper-lead-zinc from cyanide tailing by means of floatation belongs to the field of nonferrous metal separation. The processing procedures of the method are as following: (1) mashing: the cyanide barren solution is added into the cyanide tailing and stirred to ore slurry, the concentration of which is 35 to 40 per cent; (2) lead-zinc preferential flotation: after being stirred, the ore slurry is put into flotation machine and lime, Ethyl thiocarbamate and Sodium n-butyl xanthate synthetic are added in to the ore slurry. The course of once rough floatation, twice scavenging and twice concentration is processed to recover Zinc and Lead; (3) Cu-S separation: after the tailing of lead and zinc bulk flotation is concentrated, the cyanide barren solution is added into the tailing and the tailing is made into the ore slurry with the concentration of 35 to 40 per cent. And then, the ore slurry is put into the floatation machine and sulfate, sodium sulfite, Z-200 and ammonium butyl aerofloat are added into the tailing. The course of once rough floatation, twice scavenging and twice concentration is processed to recover copper. And the tailing can be for sale as sulfur concentrate; (4) Reuse of separation tailing water: the press filtrate of bulk concentrate, the overflow of thickener, the press filtrate of copper concentrate and the press filtrate of the sulfur concentrate return to the buffer slot of the cyanide barren solution to be used for replacement fluid. The invention has the advantages of good flotation effect, high recovery rate of the copper-lead-zinc and zero discharge of waste water and residue.

Lubricating grease for hub bearing of heavy load truck and preparation method thereof

InactiveCN103450978AEliminates tendency to overflowSlow dehydration stepThickenersThiocarbamateChemical industry
The invention relates to a lubricating grease and a preparation method thereof, particularly relates to a lubricating grease for a hub bearing of a heavy load truck and a preparation method thereof, and belongs to the technical field of a chemical industry. The lubricating grease is prepared from the following raw materials: (A) base oil which accounts for 60-85% of total weight of the lubricating grease, (B) a thickening agent, which is C12-C22 unitary organic acid which accounts for 7-12% of total weight of the lubricating grease, 0.5-3% of sebacic acid, 0.2-1% of boric acid, and 3-5% of lithium hydroxide oil solution, (C) an additive, which is thiocarbamate which accounts for 0.5-3% of total weight of the lubricating grease, 2-5% of sulfide olefin cottonseed oil, 2-4% of dialkyl dithiocarbamate salt, 0.5-2.5% of molybdenum dialkyl dithiophosphate, 0.3-2% of antirust agent and 0.3-1% of antioxidant. The lubricating grease has the beneficial effects that the production time is shortened; the lubricating grease is more controllable in process, stable in product quality, less in seepage loss of a high-temperature bearing, and prominent in extreme pressure property; lubricating protection can be better provided for hubs of the heavy load truck; the lubricating requirements of the hub bearing of the heavy load truck under various working conditions can be met; the grease exchange period of the hub bearing is prolonged.

Bactericidal composition containing azoxystrobin and thiocarbamate and application thereof

The invention belongs to the technical field of agricultural fungicides, in particular to a bactericidal composition containing azoxystrobin and a thiocarbamate fungicide and an application thereof. The azoxystrobin and the thiocarbamate fungicide are adopted for complexing, the thiocarbamate fungicide is any one of mancozeb, zineb, maneb or thiram, and the two can represent excellent synergy within a certain mix proportion range by complexing; compared with a single medicament, the bactericidal composition can significantly improve the bactericidal effect, expand the bactericidal spectrum, effectively avoid the possible problems of drug resistance, reduced efficacy and the like due to the use of the single medicament of the azoxystrobi and prolong the life cycle and the service life of the single medicament.
