Application
|
Used as a reagent for the determination of nickel and rubber vulcanizing agent
|
1.Used as a reagent for determining nickel and a rubber vulcanizer
2.Used as a vulcanizer for butyl rubber, natural rubber, styrene-butadiene rubber, etc.
3.Used as a vulcanizer for butyl rubber, natural rubber, styrene-butadiene rubber, and polysulfide "ST" type rubber, especially suitable for butyl rubber. Oxidants (such as Pb3O4, PbO2) have an activation effect on it. It is easy to disperse in the rubber compound, vulcanizes quickly, and the vulcanized rubber has high tensile strength. The critical temperature is relatively low and has a tendency to scorch. Adding certain scorch retardants , thiuram, thiazoles, and dithiocyanoformate accelerators can effectively improve operational safety. This product has discoloration and contamination agents and is only suitable for dark products. When accelerator DM is used as an activator, the scorch resistance is better than lead oxide, and the discoloration is also weakened, but carbon black rubber is an exception.
When tetrachlorobenzoquinone is used as an activator, the activation effect is much stronger than lead oxide. This product is mainly used to manufacture air bags, water tires, insulation layers of wires and cables, heat-resistant gaskets, etc. The dosage is 1-2 parts. It is combined with 10-6 parts of lead oxide or 4-2 parts of accelerator DM. p-Benzoquinone dioxime is a reagent for the determination of nickel.
