Precise measurement of calibrate in the layers of barrier in film blown
The scanner Or-Frame surpasses the limitations of the measurers of calibrate of oscillating capacity and the technology of other sensors for control of calibrate in films blown of barrier.
When coextruyen layers of film of barrier, an efficient way to keep the quality of the film blown, is the obtaining of information of calibrate in real time that derives quickly to the controller of process. The majority of the lines of blown use measurers of oscillating capacity. Since these locate near of the bubble, cater an erroneous reading for common resins like the nylon and the EVOH like result of the heat during the process and the variation of the dielectric constants for these layers of barrier. The precision of the nuclear sensors range, that are an alternative for the ones of oscillating capacity, sees engaged by the limitations of location of the head of scanned to the rotar around the bubble. This limitation is basically the result of the inherent sensitivity of the measurers type range to take the reading with linear distance and vibration of the bubble.
Battenfeld Gloucester Engineering Co, Inc. of Gloucester, Massachusetts, developed a very new scanner that, in addition to being precise, sends the signals quickly the controller of process. It has designated the scanner Or-Frame. It bases in measurers type fixed beta for reading without contact of the calibrate of multilayered films. It is effective in all type of resins of barrier without mattering the temperature of the film and caters control of calibrate in real time. In combination with the controller of Process Extrol patented by Battenfeld constitutes a very advanced system and exact.
The scanner Or-Frame mounts between the drag oscillating and the drag of secondary rollers to measure the film collapsed flat. The measurer beta finds inside a frame rectángular (Or-Frame) by where happens the film before the separation. The sensor reads with precision the two sides of the film and initiates the transmission of information when the drag oscillating hardly has turned 90°. The majority of the conventional measurers of fixed type require a complete revolution of 360° in the oscillating unit so that the measure and the calculation reach to effect before sending the data to the controller. As it indicates it Carl Johnson, manager of product of film sopladda in Battenfeld Gloucester, this process can take until 20 minutes. The scanner Or-Frame is in addition to precise, very upper in the rapidity with which transmits information to the controller above other available sensors. In fact, the information arrives to the controller between 5 to 6 minutes after the start of the drag, which is enough before the first revolution.
The scanner uses algorithms very sophisticated of processing of signals that allows to the processor Extrol of Battenfeld separate mathematically the profile of each side of the film and determine the calibrate exactly. The controller Extrol adjusts the parameters of process, with base in the information received of the scanner, and keeps the measure of calibrate required. When the system uses in group with the Automatic Controllers of Profile and the Gravimétrico, the variations of calibrate reduce drastically.
