Embodiment 1
[0029] Filling medium for extrusion molding of pipe through parts, including: 10g porcelain powder and 100g paraffin wax.
[0030] The processing method of the pipe through piece includes the following steps:
[0031] (1) heating the paraffin wax at 72°C until the paraffin wax is completely melted, then adding the porcelain powder, stirring to make the porcelain powder evenly distributed in the liquid paraffin to obtain a liquid filling medium;
[0032] (2) pour the liquid filling medium into the straight copper tube with the inner diameter of 8.00mm, after cooling, put the copper tube filled with the filling medium into the extruder and extrude it into a T-shaped tube;
[0033] (3) Heating the T-shaped tube at 72° C. to melt and remove the filling medium. After removing the filling medium, a T-shaped tube through piece can be obtained, and the height of the T-shaped tube through piece is 42 mm.
[0034] Five parts of the T-shaped pipe through piece of this embodiment are sel...
Embodiment 2
[0036] Filling medium for extrusion molding of pipe-through parts, including: 30g porcelain powder and 100g paraffin wax.
[0037] The processing method of the pipe through piece is the same as that of Example 1.
[0038] Five parts of the T-shaped pipe through piece of this embodiment are selected for wall thickness measurement, and the results of the five wall thickness measurements are: 8.01mm, 8.00mm, 6.00mm, 6.51mm, and 7.00mm, which can be seen in this embodiment. The wall thickness of the prepared T-shaped pipe through piece is relatively uniform.
Embodiment 3
[0040] Filling medium for extrusion molding of pipe through parts, including: 60g porcelain powder and 100g paraffin wax.
[0041] The processing method of the pipe through piece is the same as that of Example 1.
[0042] The wall thickness measurement is carried out at five places of the T-shaped pipe through piece of this embodiment. The five wall thickness measurement results are: 8.00mm, 8.02mm, 6.01mm, 7.00mm, and 6.00mm. From this, it can be seen that this embodiment is The wall thickness of the prepared T-shaped pipe through piece is relatively uniform.
