Embodiment 1
[0026] A wear-resistant, temperature-resistant and self-lubricating modified polyoxymethylene composite material, a process method for making a sample cover of a pneumatic sample delivery box, the method comprises the following steps:
[0027] 1. Raw material ratio (parts by weight): 70-80 parts of polyoxymethylene copolymer, 8-15 parts of polytetrafluoroethylene, MoS 2 2 to 5 parts, 1 to 2 parts of methyl silicone oil, 0.5 to 0.8 parts of antioxidant, 1 to 2 parts of active agent, 0.1 to 0.5 parts of coupling agent, and 0.1 to 0.5 parts of other additives.
[0028] 2. Mixing of raw materials: the weighed polyoxymethylene, polytetrafluoroethylene, MoS 2 Put it in a sealed mixer and mix it at a high speed of 3000 rpm for 5 to 10 minutes; then add the weighed methyl silicone oil, active agent, antioxidant, coupling agent and other additives, and mix at 3000 rpm Mix at high speed for 3 to 5 minutes separately to obtain mixed raw materials.
[0029] 3. Extrusion molding: Feed th...

The invention discloses a wear-resistant and high-temperature-resistant pneumatic sample transporting box and a preparation method thereof, belongs to the technical field of design and manufacture ofmetallurgical production equipment accessories and provides the wear-resistant and high-temperature-resistant pneumatic sample transporting box which has good wear resistance and good impact resistance effects and the preparation method of the pneumatic sample transporting box. The pneumatic sample transporting box is a high polymer material extrusion formed box containing a mixture of componentsin parts by weight as follows: 70-80 parts of kematal, 8-15 parts of polytetrafluoroethylene, 2-5 parts of MoS2, 1-2 parts of methylsilicone oil, 0.5-0.8 parts of an antioxidant, 1-2 parts of an activator, 0.1-0.5 parts of a coupling agent and 0.1-0.5 parts of other necessary aids. According to the preparation method, the mixture of the components in parts by weight is taken as a raw material, themixture is firstly preheated and then heated at 2-3 stages, and the high polymer material extrusion formed box is formed through extrusion by an extruder under the cooperation of drive of an extrusion screw and a forming outlet.
Description
technical field [0001] The invention relates to a pneumatic sample delivery box, in particular to a wear-resistant and high-temperature resistant pneumatic sample delivery box, which belongs to the technical field of design and manufacture of metallurgical production equipment accessories. The invention also relates to a preparation method for the pneumatic sample delivery box. Background technique [0002] The pneumatic sample delivery box is used as a steel sample pipeline delivery device for fast sample delivery, fast analysis, and fast feedback in the process of ironmaking, steelmaking, and out-of-furnace refining in steel mills. It is of great significance to shorten the smelting time, ensure the product quality and improve the economic benefits of the enterprise. It has been widely used in the metallurgical industry at present. [0003] As the most important long-distance transport driving part of the sample box device, the sample box cover must withstand the working ...
