sodium lignosulfonate superplasticizer are surfactants. After they are added to concrete, the hydrophobic groups are directionally adsorbed on the surface of cement particles, so that the cement has a negative charge. The cement particles with the same charge are mutually repulsed and dispersed under the action of charge repulsion. The flocculent structure formed by the cement at the initial stage of adding water becomes a dispersed structure, and the free water in the flocculent condensate is released, so as to achieve the purpose of water reducing agent.
Therefore, adding wood calcium superplasticizer into concrete can reduce the water consumption of concrete mixture, reduce water cement ratio, improve workability, facilitate pumping and improve the strength, compactness and durability of concrete.

Sodium Lignosulfonate is a natural polymer derived from wood pulp. It is a light yellow to brown powder that dissolves easily in water. It has various applications and functions in different industries such as it is used as a dispersant and binder for concrete, ceramics and gypsum. It reduces the water content and improves workability and strength in materials. It also works as a de-foaming agent and preservative for paper productions and food processing. It prevents the formation of foam and inhibits the growth of microorganisms. Itâ??s used a surfactant and emulsifier for oil drilling, dyeing, leather and cosmetics. Sodium Lignosulfonate is also used as a fertilizer and feed additive for agriculture and animal husbandry. It's also used in the textile, chemical, metallurgical and petroleum industries. Sodium Ligonosulfonate is a versatile and environmentally friendly substance that can be used for various purposes. It is also biodegradable and non toxic to human and animals.

Construction: 1. Widely used in precast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building & town planning projects and dwelling erections etc. 2. Suitable for preparation of early-strength, high-strength, high-anti-filtration and self sealing&pumpable concrete. 3. Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stage of application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peak heat summer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed. 4. Compatible with Portland cement, normal Portland cement, Portland slag cement, flyash cement and Portland pozzolanic cement etc. Others: Because of the high dispersion force and low foaming characteristics, SNF has also been widely used in other industries as Anionic Dispersing Agent. Dispersing agent for disperse, vat, reactive and acid dyes, textile dying, wettable pesticide,paper,electroplating, rubber, water-soluble paint, pigments,oil drilling, water treatment,carbon black, etc.
Product description Trade Name Sodium gluconate Chemical Name Gluconic Acid Sodium Salt CAS.No. 527-07-1 HS code 291816 Towards :Food,concrete,textile,medicine,steel,glass bottle,water quality Chemical Expression:Sodium gluconate is the sodium salt of gluconic acid, produced by fermentation of glucose. It is a white to tan, granular to fine, crystalline powder, very soluble in water. It is non-corrosive, non-toxic and resistant to oxidation and reduction, even at high temperatures. Specification Food grade soldium gluconate Character White Crystalline Powder Content > 99 % Chloride < 0.05 % Arsenic salt < 3 PPM Lead salt < 10 PPM Heavy Metals < 20 PPM Sulfate SO4 < 0.05 % Reducing Substance < 0.5 % Loss on Drying < 1.0 % Application 1. 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; 2.
