Joyreach Fdn Powder Naphthalene Water Reducing Admixture Superplasticizer for Concrete Package 25kg/50kg
Naphthalene superplasticizer has good adaptability to various cements and improves the operability of concrete.FDN has the advantage of high water reducing ratio, non-delayed coagulation, non-air entraining and strong adaptability. It can improve the workability of concrete to a large extent so as to reduce the water consumption for blending. Meanwhile, it can improve the strength of concrete.
It is widely used in concrete engineering: highway, railway, bridge, tunnel, power station, dam, high-rise building and other projects.It has good dispersion, water reduction and early-strength effect.Adding naphthalene series superplasticizer into ordinary concrete can improve the physical and chemical properties of concrete, improve the concrete strength, construction speed, project quality, technology and working conditions.
1. early strength admixture - improve construction progress;
2. retarding admixture - prevent cracking of large infrastructure such as airports and bridges;
3. pumping type admixture - transported by pump, such as high-rise buildings;
4. antifreeze admixture - used for winter construction.
FDN-A High concentration product with sodium sulfate content no more than 5 percent.
FDN-AI Middle concentration product with sodium sulfate content no more than 10 percent.
FDN-AII Low concentration product with sodium sulfate content no more than 18 percent.
FDN-23 sodium sulfate content no more than 23 percent,cheapest type to save cost.
Usage method:
--Powder 0.5%-1.0%, recommended dosage 0.75%;
--Liquid is 1.0%-2.0%, and the recommended mixing amount is 1.5%. The mixing amount can be appropriately increased according to the grade of concrete.
--Each batch of goods must be tested to meet the engineering requirements before use.
1. As the requirement of engineer,the dosage can be adjusted after testing.
2. It can be put into blender with mixing water,making mixing before concrete pouring,the plasticizing effect could be better.

Cobalt-chromium-molybdenum alloy (CoCrMo) is a kind of cobalt-based alloy, and is also a kind of Stellite alloy.
It is a cobalt-based alloy that is resistant to wear and corrosion. The first cobalt-based alloy was a cobalt-chromium binary alloy, which was later developed into a cobalt-chromium-tungsten ternary composition, and then later did the cobalt-chromium-molybdenum alloy develop. Cobalt-chromium-molybdenum alloy is a kind of alloy with cobalt as the main component, containing a considerable amount of chromium, molybdenum and a small amount of nickel, carbon and other alloying elements, and occasionally also containing iron.

Vanadium(V) shares properties with its source material. Vanadium is a chemical element with symbol V and atomic number 23. It is a hard, silvery-grey, ductile, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation Vanadium is electrically conductive and thermally insulating, and itâ??s harder than most metals and steel. It has good resistance to erosion and it is stable against alkalis and sulfuric and hydrochloric acids. It is oxidized in air at about 933 K(660 °C, 1220 °F), although an oxide passivation layer forms even at room temperature.

Chromium has high corrosion resistance against many different acids and bases as well as hot gases. Chromium is used as a wear-resistant coating to increase the service life of specific components in combustion equipment. Besides, chromium is often used as a brilliant decorative coating for operating elements on appliances or jewelries.

Silicomanganese Slag
Felman Production generates a residual commercial by-product, silicomanganese slag, through the production of Ferro Silicomanganese (FeSiMn). The slag is an inert solid green material consisting primarily of aluminum, manganese, magnesium, silicon, and calcium oxides.
Production
The slag is generated during the production of ferro silicomanganese using electric arc furnaces. The molten slag is casted, cooled by spraying it with cold water, and then crushed to the desired size.
Potential Uses
Potential uses of the commercial by-product include re-melt/reproduction, industrial fill, road base, textiles manufacturing, etc.
Chemical Composition
Below please find the available metals totals for the chemicals that were detected as components of the slag material. The material is considered non-hazardous as shown by Toxicity characteristic leaching procedure testing conducted on the material. A qualified and licensed environmental laboratory is currently conducting a general assay of the material to determine the % w/w of the different chemical components.
