Embodiment 1
[0023] A microwave curing method for blocks, comprising the following steps,
[0024] (1) Inject the slurry into the test mold, cover it with PEEK film and let it stand for pre-curing for 3 hours. The temperature is controlled at 45°C.
[0025] (2) After the pre-curing is completed, cut with a steel wire to obtain an uncured block, then cover it again with the original covering film and transfer it to the microwave reaction chamber for microwave heating and curing for 1 hour. The frequency of the microwave is 2450MHz, and the power is 0.5kW. The output mode is continuous wave; microwave heating and curing are divided into three stages: the first stage is to raise the temperature to 60°C for 20 minutes, the second stage is to raise the temperature to 70°C and hold for 20 minutes, the third stage is to cool down to 60°C for 30 minutes, and control the temperature of the first stage. The heating rate is 3°C / min, the heating rate of the second stage is 2°C / min, and the cooling rat...
Embodiment 2
[0028] A microwave curing method for blocks, comprising the following steps,
[0029] (1) Inject the slurry into the test mold, cover it with a polytetrafluoroethylene film and let it stand for 2.5 hours for pre-curing, and the temperature is controlled at 40°C.
[0030] (2) After the pre-curing is completed, the uncured block is obtained by cutting with a steel wire, and then covered with the original covering film and transferred to the microwave reaction chamber for microwave heating and curing for 1 hour. The frequency of the microwave is 915MHz, the power is 5kW, and the output The method is continuous wave; microwave heating and curing is divided into three stages: the first stage is to raise the temperature to 55°C and keep it for 22 minutes, the second stage is to raise the temperature to 65°C and keep it for 23 minutes, and the third stage is to cool down to 55°C and keep it for 35 minutes to control the temperature rise of the first stage The rate is 4°C / min, the hea...
Embodiment 3
[0033] A microwave curing method for blocks, comprising the following steps,
[0034] (1) Inject the slurry into the test mold, cover it with PEEK film and let it stand for pre-curing for 2 hours. The temperature is controlled at 35°C.
[0035] (2) After the pre-curing is completed, cut with a steel wire to obtain an uncured block, then cover it again with the original covering film and transfer it to the microwave reaction chamber for microwave heating and curing for 1.5 hours. The frequency of the microwave is 2450MHz, and the power is 3kW. The output mode is a combination of continuous wave and pulse wave; microwave heating curing is divided into three stages: the first stage is to raise the temperature to 55°C and keep it for 25 minutes, the second stage is to raise the temperature to 70°C and keep it for 25 minutes, and the third stage is to cool down to 55°C Keep it for 40 minutes, control the heating rate of the first stage to 2°C / min, the second stage's heating rate to...
