There are HPEW units on bimodulus sizing applicator, electricity, gas and water unit, also for walking on stage for operating;And rubber roll is water
Cold, using rubber covered roll shell;The diameter of rubber roll and the middle breadth by paper machine high, speed and line pressure are determined;In the first rubber roll 700
Make holding stabilization in applying glue with the temperature that the recirculated water of the second rubber roll 100 makes rubber roll.
Scram button being provided with bimodulus sizing applicator, previously just having needed to press scram button when there is me.
Using the rubber roll of two roller size press, i.e., usual two diagonals arrangement to force together traditional top sizing, glue more
Liquid forms a Jiao Chi above nip, and page adsorbs certain sizing material, completes Process of Applying Glue by nip, but with paper machine
The raising of speed, the drawbacks of the use of two roller size press exposes more and more:
Speed is higher, and the roll neck of application roll gets over increasing, and the sizing material formed with reducing roller to run at high speed is thrown and splashed, but due to
Roller runs at high speed excessive to the disturbance of sizing material, makes resin added skewness in the horizontal, while the increasing of roll neck, transmission consumption
Also accordingly increase.
In order to increase the mobile phase of glue, it is ensured that resin added it is uniform, with the raising of speed, the concentration reduction of glue,
And then after increased drying portion steam cost.
The utility model also provides bimodulus sizing applicator, and this bimodulus sizing applicator can respectively implement indented form applying glue and film transfer is applied
Glue, the function of realizing whole sizing applicator is more extensive, while can solve the problem that the top sizing of transmission obtains problem.
