Protection management regulations：
The tape machine protection installation must meet the following requirements:
6. All belt conveyors drive the drum section and the tail drum to install an over-temperature and automatic smoke sprinkler, and must be installed near the drum to ensure that the automatic sprinkler can effectively extinguish the fire in the event of fire; the water supply system is guaranteed to be unblocked, and no artificial shutdown is allowed. .
Temperature Sensor Installation Standard A temperature sensor is required at each drive roller. The temperature sensor should be mounted along the middle (axial) of the drive roller, 100 mm from the roller surface.
Smoke sensor installation standard For the belt conveyor using the unloading roller as the driving roller, the smoke sensor should be installed directly above the drum, no more than 1000mm from the surface of the drum; for the ordinary driving belt conveyor, the smoke sensor should be installed on the upper roller The middle position of the frame is 1000mm behind the lower air flow side driving roller.
Offset installation requirements: The action point of the deviation switch is not more than 50MM from the outer edge of the idler on the belt conveyor. The deviation between the deviation and the belt surface is 90 ° ± 5 °; the deviation switch must be fixed with a special shelf and must not be swung;
Commonly used BOPP films include: ordinary biaxially oriented polypropylene film, heat-sealed biaxially oriented polypropylene film, cigarette packaging film, biaxially oriented polypropylene pearl film, biaxially oriented polypropylene metallized film, matte film, and the like. The performance parameters and main uses of the various films are as follows:
Ordinary BOPP film
Uses: Mainly used for printing, bag making, adhesive tape and compounding with other substrates.
Performance: * High transparency and gloss * Excellent ink and coating
Water vapor and grease barrier properties with excellent adhesion * Low electrostatic performance Common thickness: 15, 19, 20, 25, 28, 35, 38, 40, 45jim
