Other dispersants

When the internal combustion engine is working, the engine oil is subjected to high temperature and high pressure. It comes into contact with oxygen and various metals to undergo oxidative condensation and decomposition, forming a series of substances that will be deposited and attached to the engine parts in the form of carbon deposits, paint films and sludge, making the engine work

Organic pigments have bright colors, bright tones, and low toxicity. They are increasingly used in the coatings industry. Especially the emergence of some high-performance organic pigments makes it possible to prepare various high-performance coatings.

The determination of the added amount usually requires consideration of the following factors: Type and quality of carbon black: Different types and qualities of carbon black may require different amounts of Dongfugui dispersant. For example, the amounts of low-pigment carbon black, high-pigment carbon black, and conductive carbon black are completely different.

Carbon black is a black powdery substance produced by incomplete combustion or thermal cracking of hydrocarbon compounds under strictly controlled process conditions. Its main component is elemental carbon and contains a small amount of oxygen, hydrogen and sulfur. Carbon black particles are approximately spherical in shape and have a particle size between 10 and 500 μm. They are one of the oldest industrial products.

The construction performance of refractory castables depends on its thixotropy and fluidity. In order to improve the fluidity of refractory castables, an effective measure is to increase water consumption.

The function of the water-based paint dispersant is to disperse the pigments and fillers very finely and evenly in the paint to prevent the occurrence of sedimentation, agglomeration and flocculation. Especially in water-based systems, affected by the viscosity, the pigments and fillers are affected by their own gravity. , is prone to sedimentation, so it is necessary to add a dispersant to improve storage stability.

Eight major functions of dispersants in coatings A dispersant is a surfactant that has two opposite properties: lipophilic and hydrophilic in the molecule. In coatings, the use of dispersants not only reduces viscosity, but also affects the final performance of …
