The Kangson Vinyl Sheet Factory promotes the development of recycling technology in a planned manner.
The factory has formed its April 15 technical innovation shock brigade with talented persons and encouraged them to play a leading, pivotal role.
It motivates all the employees to take an active part in developing and introducing new technologies in various ways, including giving preferential treatment to the technicians and workers who present new ideas and original plans and having several employees assist the scientists and technicians who are invited from scientific research institutes and advanced units for helping the factory develop and apply new techniques.
This has stimulated the employees’ interests in and enthusiasm for developing recycling technology and boosted the level of recycling steadily.
The factory has remodelled once again a plastic waste washing process this year.
“Washing plastic waste is a crucial factor in enhancing the quality of vinyl sheets. In other words, the quality of the sheets is mainly decided by how well the raw materials are washed,” said the chief engineer of the factory.
Its previous washing process was able to wash plastic waste five times.
It set the goal of washing it seven times and buckled down to it.
The site for the process was a main problem. Frequent washing required more water tanks, but the existing ground was limited.
Therefore, it introduced a plan of gathering all plastic waste regenerators dispersed in different places on the first floor and delivering plastic waste cleaned five times on the ground floor to the first floor along a conveyor before processing, thus ensuring two times of additional washing by a mechanical method during transport.
The plan proved highly effective.
It remarkably increased the quality indices of vinyl sheets for farming and halved labour for the washing process.
The vinyl sheet production process using plastic waste was further refined technically, consolidating the foundation for improving quality.
The factory also refashioned the plastic waste regenerators into a blast-type one.
Each regenerator had two large-capacity motors and a great deal of electricity used to be consumed when five regenerators were in operation.
Focusing on this point, the factory decided to remodel the regenerators. The remodelled regenerators would have only one motor each, thereby bringing great economic benefits.
The employees pooled their ideas and efforts to refashion them.
A 19-year-old worker came up with an idea of increasing the actual extraction rate in the process of drying raw materials and a skilled worker installed an automatic temperature controller to make the management of equipment more convenient and ensure high quality of plastic materials.
The factory also pushes the development of additives, which had been regarded as impossible to do by itself, in order to produce vinyl sheets of different uses from plastic waste.
“Developing the additives is crucial to ensuring glossiness and toughness of sheets,” said a technician.
