C3H6N6 Sulfonated Melamine Formaldehyde Resin White Crystals Synthetic Tanning Agent

Sulfonated Melamine Formaldehyde Resin Leather Tanning Agent White Crystals

JF SULFONATED MELAMINE FORMALDEHYDE RESIN Product Introduce:

Sulfonated Melamine Formaldehyde(Melamine), commonly known as melamine, protein essence, molecular formula is C3H6N6, IUPAC named "1,3,5-triazine-2,4,6-triamine", is a kind of triazine nitrogen-containing heterocyclic organic Compounds are used as chemical raw materials. It is white monoclinic crystals, almost odorless, slightly soluble in water (3.1g/L at room temperature), soluble in methanol, formaldehyde, acetic acid, hot glycol, glycerin, pyridine, etc., insoluble in acetone, ethers, and harmful to the body Harmful, can not be used in food processing or food additives.

Sulfonated Melamine Formaldehyde Resin Chemical Properties:

Non-flammable, stable in nature at room temperature. The aqueous solution is weakly alkaline (pH=8), and can form melamine salts with hydrochloric acid, sulfuric acid, nitric acid, acetic acid, oxalic acid, etc. Under neutral or slightly alkaline conditions, it condenses with formaldehyde to form various methylol melamines, but under slightly acidic conditions (pH=5.5-6.5), it undergoes polycondensation with methylol derivatives to form resins.

When hydrolyzed by strong acid or strong alkaline aqueous solution, the amine group is gradually replaced by the hydroxyl group to form cyanuric acid diamide first, further hydrolyzed to form cyanuric acid monoamide, and finally cyanuric acid.

Sulfonated Melamine Formaldehyde Resin Usage:

Sulfonated melamine formaldehyde resin superplasticizer belongs to a kind of water-soluble polymer resin. It is colorless and has good thermal stability. When used in concrete mixture, it has good dispersibility to cement, high water reduction rate, and early strength effect. Obviously, it basically does not affect the setting time and air content of concrete. The melamine formaldehyde resin superplasticizer has a high water reduction rate, and the water reduction rate can reach 15% to 25% within the dosage range, and the durability of concrete can be significantly improved.

Due to the air-entraining component, the concrete added to the product has good impermeability and frost resistance, does not contain chlorine salt, and will not corrode steel bars. The early strength effect is obvious, and the later strength is greatly improved. The 3d and 7d strength increases rapidly, and can increase by 20%-25% compared with the benchmark concrete, and the 28d strength can reach 120%-135% compared with the benchmark concrete.

Melamine formaldehyde resin superplasticizer is suitable for industrial and civil construction projects, precast, cast-in-place, early-strength, high-strength, super-high-strength concrete, steam-cured concrete, and super-impermeable concrete projects. In addition, it can also be used in special projects such as gypsum products, colored cement products and refractory concrete.
