Specifications

Coal water slurry additive (CWSF additve/CWS additive) can increase the hydrophily of coal powder and form a water film at the surface of coal powder. After using CWS additive, the dynamic viscosity of CWS can be increased and have better flowability. Moreover, concentration and stability of CWS can be improved with coal water slurry additive. Furthermre, the combustion of CWS can be more efficiently with less residuals.

Our CWS additive have widely adaptability to various coals and different technologies. Easy to use.

High purity sodium gluconate powder chemical additives

High purity sodium gluconate powder chemical additives

High purity sodium gluconate powder chemical additives

Description:

The sodium gluconate is polyhydroxy sodium carboxylate, it is also called sodium pentahydyoxycaproate, the molecular formula is C6H11O7Na, the molecular weight is 218.14, and it is white or light yellow crystalline particles or powder in appearance, easily soluble in water, slightly soluble in alcohol, and insoluble in ether. It is mainly used for acidbase balance agents, water quality stabilizers, surface cleaners, cement admixtures and so on, with wide application.

Application:

1. Adjust the acidbase balance in human bodies to restore the normal function of nerves when used for medicine. It is used for food additives for the same purpose;

2. Used as a water quality stabilizer. Its advantages are shown as follows:

I. Has apparent coordination effect, is applicable to various formulas such as molybdenum, silicon, phosphorus, tungsten and nitrite, and greatly improve corrosion inhibition effect due to the influence of coordination effect;

II. Contrary to general corrosion inhibitors, the corrosion inhibition efficiency is increased with the rise of the temperature;

III. Meet the technical requirements of scaleinhibiting abilities, has strong complexing capacity on Ca, Mg and Fe salts, and especially has excellent chelating effect on Fe3+;

IV. As a corrosion and scale inhibitor for circulating cooling water, it is superior to other corrosion and scale inhibitors used at present, and can achieve the effect of public nuisance removal.

3. Used as a steel surface cleaner: if steel surfaces need to be platinum, chromium, tin and nickelplated for special uses, the surfaces of their billets all need to be strictly washed to make coatings and steel surfaces firmly bound, and the adding of the sodium gluconate into their cleaning agents will achieve perfect effect at this time;

4. Used as a cleaning agent special for glass bottles: the professional cleaning agent for glass bottles with the sodium gluconate as a main formula can improve the following frequently asked problems: poor detergency, and easy blocking of nozzles and pipelines of bottle washers; unsatisfactory detergency on the rust of bottle labels and bottle necks; unsatisfactory food safety caused by trace residue (such as phosphate residue); and public nuisance formed by the discharge of washing water;

5. Used as a cement admixture: after a certain amount of sodium gluconate is added into the cement, it can improve the plasticity and strength of the concrete, and has retardation effect, namely postpone the initial and final setting time of the concrete;6. Can be used for industrial fields such as electroplating, film manufacturing and so on.

Naphthalene based superplasticizer with high purity

Naphthalene based superplasticizer with high purity

Naphthalene based superplasticizer with high purity

Description:

The naphthalene superplasticizer is a chemically synthesized non-air-entrained superplasticizer, with chemical name of naphthalene sulfonate formaldehyde condensate. It has strong dispersion effect on cement particles and good use effect of preparing super flowing concrete as well as cast in situ concrete and precast members with early strength and high strength requirements, can comprehensively improve various properties of the concrete, and is widely applied to highways, bridges, dams, harbors, tunnels, electric power, water conservancy as well as industrial and civil architecture, steam-cured and naturally-cured precast members and so on.

Product Performance:

1. Reduce 10 to 25 percent of cement content when the strength and the slump of the concrete are basically same.

2. When the water cement ratio is constant, it improves the initial slump of the concrete by more than 10cm, and the water-reducing ratio can reach 15 to 25 percent.

3. Has remarkable early strength and strengthening effects on the concrete, and improve the strength by 20 to 60 percent.

4. Improve the workability of the concrete and comprehensively improve the physical and chemical properties of the concrete.

5. Adapt to various cements well, and is well compatible with other types of 0s.

6. Particularly applicable to the following concrete projects: flowing concrete, plasticized concrete, steamcured concrete, impermeable concrete, waterproof concrete, naturally cured precast member concrete, reinforcing steel bars and prestressed reinforced concrete, high-strength and ultra-high-strength concrete.
