If you are interested in concrete additives, you must not miss this news. We are a professional manufacture of concrete additives, the most important product in concrete additives is water reducer. But what is concrete plasticiser? Let me show you:
As a kind of concrete additive, concrete plasticiser is also very important. What is concrete plasticiser? Plasticizers are a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to reduce its viscosity or to reduce friction during its manufacturing process.
Usually 1-2% plasticizer per unit weight of cement is sufficient. Adding excess plasticizer will cause excessive segregation of the concrete and is not recommended. Depending on the specific chemicals used, using too much plasticizer may cause retardation.
Plasticizers are typically produced from lignosulfonates, which are by-products of the paper industry. Superplasticizers are usually produced from sulfonated naphthalene condensates or sulfonated melamine formaldehyde, although newer products based on polycarboxylate ethers are now available.
Traditional lignosulfonate-based plasticizers, naphthalene and melamine sulfonate-based superplasticizers disperse the flocculated cement particles through an electrostatic repulsion mechanism. In ordinary plasticizers, the active substance is adsorbed and stuck to the cement particles, making them negatively charged, causing repulsion between the particles.
Lignin, naphthalene and melamine sulfonate superplasticizers are organic polymers. The long molecules wrap them around the cement particles, giving them a highly negative charge that repels each other.
Polycarboxylate ether superplasticizers (PCE) or just polycarboxylates (PC) act differently from sulfonate-based superplasticizers to disperse the cement through steric stabilization. This dispersed form is more effective and improves the workability of the cementitious mixture.
Sodium Lauryl Ether Sulfate (SLES) is a commonly used ingredient in many personal care products such as shampoos, body washes, and toothpaste. It is also used in industrial cleaning agents and detergents.
About sodium lauryl ether sulfate （sles 70% ）application Introduction of sodium lauryl ether sulfate （sles 70% ） Sodium lauryl ether sulfate (SLES 70%) is a
SLES 70% is a specific concentration of Sodium Lauryl Ether Sulfate (SLES), which is a commonly used surfactant in many personal care and household cleaning products.
Plasticizers are additives that are added to a polymer matrix to increase its flexibility, toughness, and workability.
Polycarboxylate superplasticizer, a vital ingredient in the construction industry, plays a key role in enhancing the workability and performance of concrete.
Alkylbenzenesulfonic acids are a type of organic compound that has a benzene ring with a sulfonic acid group and an alkyl chain attached to it.
