Method for controlling deinking process using contact angle |
摘要 |
In a deinking process at least comprising the step of stripping ink from wastepaper as the starting material and the step of removing the stripped ink from a flotation system, the contact angle of the aqueous solution portion of a slurry containing the stripped ink with the interfaces of ink particles in the flotation step is controlled to be at least 70°.
