Embodiment 1

[0023] Accompanying drawing has provided an embodiment of the present invention, can find out by accompanying drawing, the present invention relates to a kind of ultra-long bar polytrifluorochloroethylene manufacture method, adopts vertical compression molding method, a vertical compression molding equipment is set type compression molding die, the core part of the vertical compression molding die is attached figure 1 As shown, the core part of the abrasive tool includes the upper and lower pressure rods 1, the upper and lower material chambers 2, the upper and lower sliders 3, the plastic cavity 4, the locking bolts 5, the heater 6, and the upper and lower pressure rings 7; There is an upper and lower slider 3, and by controlling the minimum height of the upper and lower slider 3 and the polychlorotrifluoroethylene bar for molding, the height of the super-long material is ensured; then the molding raw material is selected, the parameters of the molding equipment are controlled...

Embodiment 2

[0042] The basic principle of embodiment two is the same as embodiment one, but the raw materials that adopt and process parameter are slightly different;

[0043] The raw material is Daikin material, choose M-300H, M-300P or M-300 powder; M-300 is powdery, with an apparent density of 0.6; M-300H is granular powder, with an apparent density of 0.95; M-300P For particles, the apparent density is 1.10. After repeated tests, the best model ranking suitable for vertical compression molding is: M-300H is better than M-300P is better than M-300.

[0044] Determination of plasticizing process temperature:

[0045] According to the material characteristics of polytrifluorochloroethylene, its melting point is 210-212°C. Through experiments, when the temperature reaches 340°C, the material will decompose. Therefore, the molding plasticizing temperature range should be higher than the melting point of 212°C and lower than the decomposition temperature of 340°C.

Abstract

A method for making ultra-long rod polychlorotrifluoroethylene, which is characterized in that: a vertical compression molding method is adopted, a vertical compression molding mold is set in the compression molding equipment, and an upper and lower slider is arranged on the vertical compression molding mold, through Control the minimum molding height of the upper and lower sliders and the polytrifluorochloroethylene rod to ensure the height of the super-long material; then select the molding raw material, control the parameters of the molding equipment, and at the same time ensure the fluidity and corrosion resistance of the raw material by controlling the process parameters , so that the material can meet the required performance requirements during molding.

Description

technical field [0001] The present invention relates to a manufacturing method and system device of a chemical material, in particular to a manufacturing method and a manufacturing system device of an ultra-long polychlorotrifluoroethylene rod, which is mainly used for manufacturing an ultra-long rod with a diameter of about 50 mm and a length of more than 200 mm. The polychlorotrifluoroethylene round rod product belongs to the technological research field of the super-long rod formed by vertical molding of the meltable fluoroplastic polychlorotrifluoroethylene (PCTFE) in the field of deep processing of polymer materials. Background technique [0002] Polychlorotrifluoroethylene (PCTFE) is one of the varieties with good mechanical strength and low temperature resistance (not brittle in -200°C environment) in the series of meltable fluoroplastic materials. It has been widely used in liquid oxygen, liquid nitrogen and Sealing of strong corrosive media in other low temperature ...
