The invention discloses a protective film having fire-resistant performance. The protective film comprises a protective film body, wherein the protective film body consists of a damp-proof layer, a flame-retardant layer, a flame-retardant ring, a permeation-proof layer and a fireproof layer, the top of the damp-proof layer is fixedly connected with the bottom of the flame-retardant layer through a first bonding layer, the top of the flame-retardant layer is fixedly connected with the bottom of the circular-ring-shaped flame-retardant ring, the outer surface of the flame-retardant ring is provided with cooling holes arranged in an equally spaced mode, and the top of the flame-retardant layer is further fixedly connected with a resin layer. The protective film having fire-resistant performance can effectively block outside high temperature and flames, burning and melting deformation of the protective film are effectively avoided, the fireproof performance is high, a fireproof and high-temperature-resistant effect is good, damage caused by too high internal temperature of the protective film is effectively avoided, a heat insulation effect is good, the protective film is effectively prevented from getting wet or being damaged, the stability of the protective film is ensured, normal usage of people can be effectively achieved, and the fireproof performance is high.

The invention provides an apparatus for polishing three-dimensional printed plastic / resin pieces. The apparatus comprises a polishing chamber and a solvent storage tank which are communicated with each other by use of a liquid inlet pipe; the apparatus is characterized in that the polishing chamber is an airtight container, an exhaust opening of the polishing chamber is connected with an air inlet of a vacuum device, an air outlet of the vacuum device is connected to the outside atmosphere and the solvent storage tank, respectively, and a switch is used for controlling the vacuum device to be connected with or disconnected from the polishing chamber, the solvent storage tank and the outside atmosphere, respectively. The apparatus for polishing the three-dimensional printed plastic / resin pieces is environmentally-friendly, capable of effectively polishing to-be-polished pieces with complex structures, and also capable of quickly recovering the hardness of the polished pieces.

A kind of electrode, the electrode strength is higher, not easily deformed, for this reason, the present invention also provides the processing method of this electrode, described electrode is integral electrode, and described integral electrode is assembled into one by N electrodes, N≥2, so The overall electrode is provided with a through groove, and grooves and protrusions are arranged in the through groove, and the grooves and protrusions are matched with the deep and thin-walled protrusions and grooves of the tubular core. The electrode is an integral electrode, and the integral electrode is assembled by N electrodes, N≥2, and the integral electrode is provided with a through groove, and a groove and a protrusion are arranged in the through groove, and the groove and the protrusion The protrusions are matched with the deep and thin-walled protrusions and grooves of the tubular core.

The invention is applicable to the field of medical treatment device, and provides a protecting method of a ball tube; the method includes steps of acquiring heat capacity value of a ball tube target face in real time; judging if the heat capacity value of the ball tube target face reaches preset nominal value; if reached, stopping the exposure of the ball tube target face; if not, continuing to expose the ball tube target face. The embodiment can detect the heat capacity value of the ball tube target face while set the nominal value in real time; according to the heat capacity value, the method applies measures such as stopping exposure or continuing to expose, and solves the problem that the prior art cannot detect the heat capacity value of the ball tube target face, avoids the melting and deformation of the ball tube target face, and improves the service life of the ball tube.

The invention provides a power safety protection socket based on a magnetic buckle, and relates to the technical field of power safety sockets. The power safety protection socket comprises a socket, and jacks are formed in the socket; electric shock pieces are fixedly installed in the jacks, and flow deflectors are fixedly installed at the inner sides of the electric shock pieces; conductive pinsare fixedly installed at the left side of the electric shock pieces in the jacks, and a plug is inserted into the jacks; a telescopic rod is slidably connected to the center of the socket, and a sliding block is fixedly installed on the periphery of the telescopic rod. According to the socket, when short circuit and arcing phenomena occur in the socket, the plug can be automatically popped up, sothat power failure of an electric appliance is completed, grounding processing is carried out on current, damage to a circuit and the electric appliance caused by the short circuit and arcing phenomena is avoided, heating deformation of the socket and the plug is avoided, and the safety coefficient of the socket is improved.
