Fischer-Tropsch wax can be used in plastic processing, such as injection molding, extrusion and pelletizing industries. In the production process of masterbatch and modified plastics, Fischer-Tropsch wax contributes to the dispersion of fillers and excellent smoothness during mixing. It can be used as an external lubricant for PVC. The low viscosity can increase the production speed of the product. It helps to disperse the pigments and fillers during mixing. It is especially useful in the extrusion of high-viscosity systems. It is more than ordinary PE WAX. 40-50% less, and can significantly improve the surface gloss of the product. When using intense colors, the melted Fischer-Tropsch wax can effectively wet the dye and reduce the extrusion viscosity.
When used in the ink as a particulate powder, it can improve the wear resistance and wrinkle resistance of the applied material. When applied to the coating, it can have a wrinkling effect, and when used in a micro powder state, it can form a wrinkle effect of stripes and water lines. When powder coating resin is added, it plays a role of lubrication in the extrusion process, which can reduce screw torque, reduce energy consumption and improve production efficiency.

The main parts of D series multi stage centrifugal pump are: inlet section, middle section, outlet section, impeller, guide vane baffle, water outlet guide wing, shaft, sealing ring, balance ring, shaft sleeve, tail cover and bearing body.
The water inlet section, the middle section, the guide vane baffle plate, the water outlet section guide wing, the water outlet section and the tail cover are made of cast iron, which forms a pump working chamber.
The impeller is made of cast iron in quality, leaves the liquid along the axis of the impeller before and after compression in unilateral, unequal, inevitable existence of axial force, the axial force borne by the balance disc, the impeller manufactured by static balance test.
The shaft is made of high quality carbon steel, the middle is provided with an impeller and is fixed on the shaft with a key, a shaft sleeve and a shaft sleeve nut. One end of the shaft is provided with a coupling component which is directly connected with the motor.
The sealing ring is made of cast iron, to prevent high-pressure water pump parts are respectively fixed on the water inlet section and the middle section, for wearing parts, can be replaced by spare parts wear.
The balance ring is made of cast iron and is fixed on the water outlet.
The balance disc is made of wear resistant cast iron and is arranged on the shaft, and is positioned between the water outlet section and the tail cover, and the axial force is balanced.
The shaft sleeve is made of cast iron, which is located in the packing chamber, and is used for fixing the impeller and protecting the pump shaft.
The bearing is a single row radial ball bearing.
Packing seal, to prevent air entering and a large amount of liquid leakage, packing by water filling chamber, and the end cover of the packing gland, packing ring and filler composition, function as water seal of high pressure water flows into the packing room in a few. The tightness of the packing must be appropriate, not too tight or too loose, with fluid droplets exudation prevail. If the packing is too tight, the shaft sleeve is easy to heat and consumes power at the same time. Packing is too loose, due to fluid loss to reduce the pump efficiency.
D series multi-stage centrifugal pump product features:
1, advanced hydraulic model, high efficiency, wide range of performance.
2, pump running smoothly, low noise.
3, seal with soft packing seal or mechanical seal, sealing safety and reliability, simple structure, easy maintenance.
4, the shaft is a fully sealed structure, to ensure that no contact with the media, not rust, long service life.
Application scope:
Suitable for the industry and the city water supply and drainage, high-rise building pressurized water, garden irrigation, fire booster, long-distance water, heating, bathroom pressurization of cold and hot water circulation equipment, especially suitable for boiler.
