The application of Fischer-Tropsch wax in the processing of filler grains. The appearance of Fischer-Tropsch wax has brought good news to industries such as fillers, PVC, hot melt adhesives, and road marking paint. Fischer-Tropsch wax is mainly produced by relatively The composition of straight-chain, saturated high-carbon alkanes with a molecular weight of 500-1000 gives this chemical a fine crystal structure, high melting point, narrow melting point range, low oil content, low penetration, and low mobility , low melt viscosity, hardness, wear resistance and high stability.
Application of Fischer-Tropsch wax(FT Wax) in filling grain processing:
1. The good dispersion and wetting properties of Fischer-Tropsch wax itself play a vital role in the processing of plastic products.
2. The compatibility between Fischer-Tropsch wax and polymer is small, and it is easy to migrate from the inside of the polymer to the surface during processing, and it is oriented at the interface to form a lubricant molecular layer through physical adsorption, which can reduce The friction between the polymer and the surface of the equipment prevents it from adhering to the mechanical surface, thereby improving the flow performance. The Fischer-Tropsch wax has a certain compatibility with the polymer, and the compatibility increases at high temperatures. Large, produces a plasticizing effect, weakens the cohesion between polymer molecules, reduces internal friction, reduces bulk viscosity and increases fluidity.
3. Due to its small molecular weight and low kinematic viscosity, Fischer-Tropsch wax has good wetting properties for inorganic pigment particles, reduces the probability of particle collision, thereby improving the dispersion effect of pigments, and the higher hardness of Fischer-Tropsch wax It will also improve the anti-friction effect of the masterbatch.
In plastic filled grains, due to the addition of a large amount of inorganic fillers, the characteristics of the plastic are greatly reduced, which requires low viscosity, high hardness, and high dispersion wax as a dispersion lubricant to adjust the The surface conditions of the organic matter enable it to be effectively and evenly dispersed into the carrier, reduce the wear and tear of production equipment and production energy consumption, and ensure the good performance of the grain in downstream use.
In functional grains, due to some special requirements, materials with different properties are added to the carrier, and the addition of wax can reduce the viscosity of the grains during processing, so that they can have reasonable processing speed and power consumption, and improve The appearance of high-end products.
