2results about How to "Realize the release function" patented technology

The invention discloses an internally-added non-silicon release master batch, a preparation method and a release film with nanoscale roughness, preparation raw materials comprise PET resin I, a non-silicon release agent composition and an antioxidant, and the non-silicon release agent composition comprises polyester wax and oxidized polyethlene wax. According to the invention, polyester wax and oxidized polyethlene wax are compounded, and a release functional phase which is uniformly dispersed in nanoscale and has a stable interface is constructed in a PET matrix through a unique molecular synergistic effect and a processing technology matched with the polyester wax and the oxidized polyethlene wax, so that the fundamental contradiction that the surface of an internally added release film is rough and the release function is difficult to consider at the same time is solved; and meanwhile, silicon migration pollution is fundamentally eradicated, the process is simplified by utilizing an internal addition process, and recycling is facilitated.

This invention discloses a locker with indicator markings, including a locking indicator unit, a locker, a drive assembly extending through the locker, a locking component connected to the drive assembly, and an indicator component connected to the drive assembly. The advantages of this invention are that it enables locking and indicating the usage status of the locker using only a unidirectional rotation of the handle, and also allows for unlocking in both states.
