Reporter Wu bulihasmu
Recently, the reporter noticed during an interview in the rubber joint workshop of the ethylene plant that an honorary Kanban was hung on the wall of the operation platform on the second floor of the solution polymerized styrene butadiene rubber post-treatment section, so he asked Yang Changhui, deputy director of the workshop, about the use of the Kanban curiously. "This is set up by the workshop to show the results of cost reduction and efficiency increase of employees and inspire other employees to actively participate in cost reduction and efficiency increase," he said. There are many stories with high gold content behind the kanban. "

The post-treatment production line of SBR unit in the rubber joint workshop is an open system, which is a section for the production of rubber products. During normal production, in addition to the qualified rubber block products, some water rubber and crushed materials can also be seen at the plant site, which is the "waste rubber" in our eyes. In case of device maintenance, startup and shutdown, and equipment maintenance, more waste rubber will be produced in this section. Zhang Yuchun, a process technician in the post-treatment section, is very distressed by these waste rubber, because every ton of waste rubber means thousands of yuan more loss. He has been thinking hard about how to turn waste glue into good glue. In order to make the waste glue into good glue, Zhang Yuchun ponders on the spot every day. Finally, after a large number of on-site statistical analysis, from last January, he led the preparation of the first version of waste rubber recovery plan and methods, which was implemented after discussion in the workshop. In the process of implementation, we carry the bucket full of waste materials, hold the water glue formed by pressing blocks, and go back and forth between the operating platform and the vertical conveyor dozens of meters away. Although the benefits have been achieved, the problems have also come. It has been found that only about 400 kg of waste rubber can be recovered every day by means of small buckets and manual handling, with low efficiency and safety risks. We should not only have benefits, but also ensure safety. Yang Changhui led the post-treatment process and equipment technicians in the workshop to brainstorm and develop a set of feasible recovery methods: add a channel between the operation platforms of 2600 and 3600 lines, transfer the picked water glue and wall glue to 3600 line through this channel with a small cart, use the standby block press to press the block, and then use the waste glue recovery unit for recovery.
Yang Changhui said that through the new channel, while reducing the labor volume of the staff on duty, it can also reduce the secondary pollution caused by the contact between people and waste rubber, so as to achieve the purpose of direct recovery of waste rubber. It has been proved that more than 200 tons of waste rubber has been recovered and nearly 2 million yuan has been achieved since the implementation of the project.

T162 products are produced in 3600 line of styrene butadiene plant in rubber joint workshop, and 15 kg net bags are used in the post-treatment packaging line. Zhang Ying, an employee of the fifth shift of the process team, found that there was too much space above the t162 packaging bag due to the difference between the stacking density and other products, resulting in unsightly and wasteful product packaging, so he proposed to the workshop the idea of changing the net content of the packaging bag from 15kg to 20kg. After evaluation and accounting, the workshop adopted this proposal. After the implementation of the project that packaging changed from 15kg to 20kg, the number of bags used per ton of glue was reduced from 66.6 to 50. Based on 4.23 yuan per bag, the packaging cost per ton of glue was reduced by 70.5 yuan. This alone can save more than 500000 yuan of cost every year. The workshop actively changes its thinking, encourages all employees to participate, and forms a good atmosphere in which all employees work together to make suggestions. The on-site setting of honor Kanban not only enhances the sense of honor and achievement of employees, but also promotes the enthusiasm of other employees to participate in improving quality and efficiency. Recently, Liu Jide, an employee of the fifth shift of the process group, put forward reasonable suggestions on the recovery of gas-phase solvent for intermittent polymerization of styrene butadiene, which was adopted by the workshop and is now in the stage of preparation and implementation.
