Ensuring safe production through the summer: The weather in western Inner Mongolia is not particularly hot; the hottest days occur around the peak of the heat season, when external temperatures exceed 35°C. Under such scorching conditions, the company first purchases some Huoxiang Zhengqi liquid and distributes it to various workshops and workstations； Due to financial constraints, all branch factories have been instructed to purchase heat prevention and cooling supplies for use at various production sites to help prevent heat-related issues. Once the company has the necessary funds, it will contact local watermelon growers to purchase some watermelons, which will then be distributed to various factories and work sites to help prevent heat stress. In terms of safety, strict inspections are carried out in accordance with the summer \"five-prevention\" requirements, ensuring no gaps or omissions are left. Special attention is paid to the inspection of major hazard sources, with company executives leading these inspections on a case-by-case basis; special inspections are also organized, and each factory is required to make corrections within a set time frame, in line with the \"five-fixation\" principles. In production, due to the hot weather, outdoor work is reduced, and maintenance activities are scheduled to avoid such times. The inspection room staff should be aware of the high-temperature areas to avoid heatstroke. On the equipment, the most affected components are the acetylene gas pipelines and the hydrogen chloride gas pipelines. Due to the lack of insulation measures, the zinc-rich topcoat applied to these pipelines absorbs a large amount of heat, resulting in a gas temperature in the mixer of 47°C. To prevent the mixer from activating its interlock mechanism, the set temperature was changed from 50°C to 55°C. A high circulating water temperature has a significant impact on the initial stage of control in the polymerization reactor; therefore, reducing the amount of initiator is used to control the temperature of the reactor. In heat exchangers that use circulating water for cooling, increase the flow rate of the circulating water as much as possible whenever feasible.
