Second, micro Corrugated Single machine forms and adhesive systems
Shocked from the micro-corrugated structure can be seen, the smaller and larger corrugated roof arc angle of corrugation (partial V-type) and small sub-degree angle, resulting in high-speed running, after forming Corrugated paper Easy to operate because of Corrugated Corrugated centrifugal force caused by the disengagement of the impact of adhesive and composite tooth shocked. Take a rational structure of positive and negative pressure Design , Can be reliably fixed in the Corrugated cardboard's shocked to complete the gum and tooth composite, they can not because of air pressure over part of the Ambassador duct deformation caused by local unglued. From a single machine in the form of point of view, the role of pressure-type air cushion to make corrugated support more stable on the corrugated stick, while the sealing performance of the structure than the vacuum to suction within the suction and the outer structure of the pressure loss and leakage of heat loss smaller, so is the main structure of high-speed production line. Micro-corrugated cardboard products from the application point of view, one shaped semi-circular suction tank better form of cardboard, it just fell on parts of wind trough edge products reduce the risk considerably.
Shocked smaller micro corrugated roof and the clouds of the corrugation arc requires a very small and precise and stable amount of glue paste. Micro-corrugated production line single machine and the glue machine coated Cots And the metering roller (rubber roller scraper, quantitative roll) is required to achieve less than 0.02 mm round beating motion accuracy to ensure that glue roller and metering roller to achieve less than 0.08 mm between the uniform paste gap glue, the glue roller surface needs to set the system to form the required thinner than conventional corrugated surface layer of the more refined grid.
3, base paper quality and process control
Micro corrugated board base paper specification and quality than conventional corrugated board base paper-based lack of more choices.
150 grams of ordinary corrugated paper around the C-type flute corrugated roof when the 1.25 mm radius of the flute in the top of arc can be very smooth transition and forming, when the same base paper into the G-diameter corrugated, the in 0.16 mm radius of the arc on the corrugated roof and the molding on the difficult transition, the bend radius is too small to make the top office paper, corrugated fiber fracture in broken flute. Therefore, the micro-corrugated better to use strength, weight less than 100 grams of water absorption and moisture permeability and uniform base paper.
Base paper quality and process control
Principle, a high-quality operation Corrugated board production line A paper strength, tension, pressure, humidity, temperature and speed glue paste formula in the ideal point of balance.
Base paper strength uneven moisture, gum paste properties of instability, the resin content control volatility and preheat heat disorders are caused by imbalances and tension changes in the speed to break the ideal point of balance.
In equipment to meet the prerequisite conditions, micro-corrugated production requires more sophisticated process control: control of base paper quality indicators, stable and accurate web tension control, base paper moisture levels before and after the process control, control the amount of adhesive and temperature control is fine the key to corrugated board production process. The whole line of them suitable precise tension adjustment, the warm dryer wrapping angle reasonably timely adjustment, stable performance, high-solid content starch gel paste, glue roller and metering roller gap between the adhesive paste the exact settings to ensure that smaller and stable adhesive volume, the increase of temperature settings and fine focus adjustment, etc. are the main means of control. The whole production line corrugated cardboard all the details are based on the quality of corrugated cardboard timely regulation and control, we can ensure that the entire production line speed stability, transmission fluid, to produce high quality micro-corrugated cardboard.
