Cr-Tablet-Chromium additives-sumetech,Cr 60% with flux,Cr 75% with flux,Cr 80% with flux,Cr 90% with flux,Cr tablet with flux
Performance:
1. Environmental protection and no pollution; The actual yield is greater than 95%.
2. Suitable for adding or adjusting chromium (Cr) in aluminum, copper and other alloys.
Usage:
1. Add temperature: â?¥730â??.
2. Joining method:
After melting the charge, stir evenly, sample analysis and calculate the amount of chromium additive. To reach the melt temperature, remove the melt surface scum, disperse the product into the molten pool everywhere (if you need to add manganese agent, copper agent, can be added at the same time).
The reaction was complete. Let stand for 10 ~ 20 minutes, then stir well for 5 minutes. Then set it for 5 ~ 10 minutes for sampling analysis. Only qualified ingredients can be transferred to the next process.
Packaging and Storage:
The product is a round dark gray lump, and the inner package is plastic bag/vacuum bag/aluminum foil package; The outer packing is cardboard box. 500g/pc, 2.5kg/ bag, 20kg/ box.
Store in ventilated and dry place, keep away from moisture.
Calcium Polysulfide Solution is used mainly as a fungicide and fertilizer for the agriculture industry, to control wide range of fungal and other plant diseases in orchards, field crops and horticulture crops; it can also be used in various treatment systems as a metal precipitating agent. Calcium Polysulfide Solution effectively stabilizes and reduces soluble metals.
Sales Specifications
Appearance: Clear, to red orange liquid
Assay:24.0-29.0%
Odor:Slight H2S odor
Density:1.25-1.29 @ 25�°C
Treatment Notes
Arsenic: Acid medium only forms various arsenic sulfides; pH>7; arsenic-sulfur compound are insoluble
Lead: Wide Range (pH: 4-9); forms lead sulfide
Copper: Close to neutral (Optimal pH: 5â??7); forms copper sulfide
Zinc: Wide range (pH: 4-9); forms Zinc sulfide
Cadmium: Wide range (pH: 4-9); forms cadmium sulfide
Molybdenum: Wide range (pH: 4-9); forms molybdenum sulfide
Uranium:Wide range (pH: 4-9); forms uranium sulfide
Cyanide: Chemical Conversion produces Thiocyanate*
*Thiocyanate can be bio-treated, or it can be treated with lime, producing calcium carbonate, gypsum and ammonia. Chromium (Cr VI) can be treated with calcium polysulfide, and the Cr(VI) is reduced to Cr (III), which is then precipitated as chromium hydroxide.
While the list above indicates effective treatment may be obtained with system pH near 4.0, TKI has found that product is most stable in systems with pH greater than 5.0, to avoid potential generation of H2S.

Zinc Oxide USP is mainly used in food industry as a dietary ingredient and as a nutrient. Zinc is an important antioxidant nutrient. It is necessary for protein synthesis, wound healing, for blood stability, normal tissue function, and aids in the digestion and metabolism of phosphorus. It also governs the contractility of muscles and maintains the body's alkaline balance. Zinc Oxide is also used in a variety of products like plastics, ceramics, glass, cement, rubbers, paints, pigments, lubricants, adhesives, sealants, batteries, ferrites, flame-retardant, and bandages. It is commonly used in personal care products like baby powders, diaper rash creams, calamine creams, antiseptic ointments, and anti-dandruff shampoos and sunscreens. It is used as an additive in the production of concrete, and as an additive in food products (breakfast cereals).USP, or United States Pharmacopeia, grade chemicals comply with the standards of the United States Pharmacopeia and National Formulary (USP-NF). USP Grade chemicals are fit for use in food, drugs, and medicines. They are subject to stringent testing and are typically required to have the highest level of purity.
