- Serve as inhibitor to styrene, butadiene, isoprene, acrylonitrile, vinyl acetate resin or rubber monomer polymerization.
- Be used for styrene, acrylate, graft neoprene adhesives and other vinyl monomer polymerization inhibitor and temperature emulsion polymerization reaction termination agent or stabilizer.
- As electroplating additive.
- Used as a detergent, corrosion inhibitor, stabilizer and antioxidant and so on, and also used in cosmetic hair dyes.
- Be used to make anthraquinone dyes, azo dyes, rubber antioxidant, stabilizers and antioxidants.
- Photometic determination of phosphorus, magnesium, copper, niobium, silicon and arsenic. Determination of iridium polarographic method and volumetric method. The reducing agent of heteropoly acids, reducing agent, copper and gold.
Package, Storage and Transportation
During railway transportation, the dangerous goods loading table in the "Dangerous Goods Transportation Rules" of the Ministry of Railways should be strictly followed. Before transportation, check whether the packaging container is complete and sealed. During transportation, ensure that the container does not leak, collapse, fall, or be damaged. It is strictly forbidden to mix with acids, oxidants, food and food additives. During transportation, it should be protected from exposure to sunlight, rain, and high temperature.
Store in a cool and ventilated warehouse. Keep away from fire and heat sources. The packaging must be sealed and cannot come into contact with air. It should be stored separately from oxidants, acids, alkalis, and edible chemicals, and must not be mixed. Equipped with fire equipment of corresponding types and quantities. The storage area should have appropriate materials to contain leaks. The "five pairs" management system for extremely toxic items should be strictly implemented.
Plastic bags or double-layer kraft paper bags outside fiberboard barrels, plywood barrels, cardboard barrels; plastic bags or double-layer kraft paper bags outside ordinary wooden boxes; threaded glass bottles, iron-capped glass bottles, plastic bottles or metal barrels (cans) outside ordinary wooden boxes; threaded glass bottles, plastic bottles or tinned thin steel barrels (cans) outside full-bottom lattice boxes, fiberboard boxes or plywood boxes.
Frequently Asked Questions
What is the purity and appearance of your Hydroquinone?
