Embodiment 1
[0058] (1) Preparation of warm mix agent
[0059] (1) Preparation and loading
[0060] Put water under the sweating dish plate; connect the sealing system of the sweating dish with the pressurized buffer tank and the compressor; install the decompression buffer tank at the lower part of the sweating dish and connect the vacuum pump; connect the jacket of the sweating dish and the movable coil with the circulation system Connect, fix the coil on the sweating dish; start the heating function of the circulation system with heat transfer oil as the medium, so that the temperature of the circulating oil will rise to 94°C.
[0061] The polyethylene wax by-produced by the high-density polyethylene plant of PetroChina Jilin Petrochemical Ethylene Plant is used as raw material (dropping melting point is 90.3°C; penetration at 25°C is 43 dmm; penetration at 55°C is >200 dmm; It can be seen that the polyethylene wax contains a large amount of low-melting point substances.), heated to 94...
Embodiment 2
[0080] (1) Preparation of warm mix agent
[0081] (1) Preparation and loading
[0082] Put water under the sweating dish plate. Connect the sealing system of the sweating dish with the pressurized buffer tank and the compressor; install the decompression buffer tank and connect the vacuum pump at the lower part of the sweating dish; connect the jacket of the sweating dish and the movable coil with the circulation system, and fix the coil in the On the sweating dish; using the heat transfer oil as the medium, start the heating function of the circulation system to raise the temperature of the circulation oil to 94°C.
[0083] Use the polyethylene wax by-produced by the high-density polyethylene plant of PetroChina Jilin Petrochemical Ethylene Plant as the raw material (the properties are the same as in Example 1), heat to 94°C and melt, then add dibenzoyl peroxide accounting for 0.03% of the weight of the raw material, and stir evenly Afterwards, add it to the sweating dish. ...
