Embodiment 1
[0022] Add 20000kg softened hot water (80-90℃), 60kg dispersant polysodium methacrylate, 25kg talcum powder, 7.5kg emulsifier alkylphenol and ethylene oxide condensate to the 26000L batching tank, start stirring for 10 minutes , add 2000kg polyethylene powder (melt index is 1.0g / 10min), after emulsifying for 40 minutes, send it into the chlorination kettle with a slurry pump, make up hot water to make the total amount 22000kg, and wash the kettle wall, add 2kg to trigger agents dibenzoyl peroxide and dicumyl peroxide. After sealing the reactor, heat it up, open the chlorine system and mass flow meter at the same time, and feed chlorine gas into the reactor to carry out the chlorination reaction. The distribution is as follows:
[0023] 75-110°C Chlorine flow 720kg, accounting for 30% of the total chlorine flow 800kg / h, time 55 minutes; pressure 0.2Mpa;
[0024] 110-125°C chlorine flow 720kg, accounting for 30% of the total chlorine flow 1000kg / h, time 43 minutes; pressure 0.3...
Embodiment 2
[0029] Add 20,000kg of softened hot water (80-90°C), 60kg of dispersant sodium polymethacrylate, 25kg of talcum powder, 7.5kg of emulsifier alkylphenol and ethylene oxide condensate into a 26,000L batching tank, and start stirring for 10 minutes , add 2000kg polyethylene powder [melt index (MI) 5kg 1.8g / 10min] and emulsify for 40 minutes, send it into the chlorination kettle with a slurry pump, make up hot water to make the total amount 22000kg, and rinse the wall of the kettle, add 2kg initiator dibenzoyl peroxide and dicumyl peroxide. After sealing the reactor, heat it up, open the chlorine system and mass flow meter at the same time, and feed chlorine gas into the reactor to carry out the chlorination reaction. The distribution is as follows:
[0030] At 75-115°C, the chlorine flow rate is 720kg, accounting for 30% of the total chlorine flow, the flow rate is 800kg / h, and the time is 54 minutes; the pressure is 0.20Mpa;
[0031] 115-125°C Chlorine flow 840kg, accounting fo...
