Superplasticizers are traditionally known for their water-reducing qualities to improve the flow of concrete.
The key technology of Fischer Tropsch wax production lies in catalysts. Commonly used catalysts are iron-based catalysts and cobalt-based catalysts. Iron-based catalysts are mainly used to produce Fischer-Tropsch synthetic waxes with a melting point below 105°C, and only cobalt-based catalysts can be used for Fischer-Tropsch synthetic waxes with higher melting points.
The appearance and performance of Fischer-Tropsch wax produced by cobalt-based catalyst are better than those produced by iron-based catalyst. In recent years, new coal-to-liquid project production lines will be put into operation one after another. It is roughly estimated that 10 million tons of coal-to-liquid series products will be produced.
Among them, there will be nearly 200,000 tons of series products that can be used in the production of wax lubricants. . By then, the competition in the wax lubricant market will be further intensified, the polyethylene wax market will be further compressed, and the inferior wax lubricants will also withdraw from the market.
Fischer-Tropsch waxes are mainly composed of linear, saturated high-carbon alkanes with relative molecular weights of 500-1000, which endow the chemical with a fine crystal structure, high melting point, narrow melting point range, low oil content, and low penetration. Degree, low mobility, low melt viscosity, hardness, wear resistance and high stability.
Compared with the general polyethylene wax (PE wax), the Fischer-Tropsch synthetic wax is significantly different in molecular weight. The molecular weight of Fischer-Tropsch wax is much lower than that of PE wax, with less branch chains and high crystallinity.
Fischer-Tropsch wax is a saturated straight-linked alkane, without double bonds, with strong anti-oxidation ability and good weather resistance. The viscosity of Fischer-Tropsch wax is much lower than that of PE wax. Only about 10. The same lubrication effect can be achieved with less dosage. The usage amount is only 70-80% of PE wax.
Fischer-Tropsch wax has good compatibility with PVC, and can be used as internal and external lubricants. It can be used as a good internal lubricant to effectively control shear conditions, promote flow, control friction and melting properties, thereby improving thermal stability. At the same time, Fischer-Tropsch wax enables PVC products to obtain the best physical and processing properties due to its high crystallinity and high linearity structure.
According to needs, the Fischer-Tropsch process can synthesize alkanes with different chain lengths to change the molecular weight of the final product to form serialized products.

A small amount of Fischer-Tropsch wax can increase the softening point of petroleum wax, thereby improving the weather resistance of wax products, but excessive addition will make wax products brittle and easy to crack or brittle, because the melting point of Fischer-Tropsch wax is high, adding too much The candle of Fischer-Tropsch wax is easy to cry during the lighting process, which affects the use time of the candle.
The product with a melting point of about 60 degrees obtained by Fischer-Tropsch wax through short-range rectification can completely replace petroleum wax for candles, crayons, and wax paper.
The production of refined Fischer-Tropsch wax products has been widely used. Fischer-Tropsch wax is a new variety in the wax market, mainly used as a substitute for traditional products such as petroleum wax and stearic acid. At present, crude wax and refined wax are available in the market, and refined wax is mainly circulated by high melting point wax.

Polycarboxylate superplasticiser (PCE) is an important component of plugging slurries.
The woodworking industry is an ever-growing industry that is constantly in need of materials that can improve the appearance of wood. Polishing wax, commonly known as wood wax, is a popular product in the woodworking industry.
Undoubtedly the most controversial wax on the market today. Paraffin is often criticized for being unsafe, but it remains one of the most well-known candle waxes. It is obtained from a petroleum refinery by-product called slack.
With the continuous advancement of science and technology in our country, the quality of construction projects continues to improve. During the actual construction process, in order to ensure the overall quality of the concrete project, admixtures are usually added to the concrete. High-performance water-reducing admixture is used as an admixture. Water-reducing admixture is added to concrete to reduce water consumption and increase the strength of concrete.
Still wondering where you can get good quality waxes in China and abroad? The journey to find the best industrial and non-industrial waxes ends here. With the growing demand for industrial waxes, the Dongke group is committed to producing the finest quality waxes, which are imported in the form of crude oil from all over the world. These are then formulated accordingly to product requirements or customer specifications.
