Embodiment Construction

[0026] Now analyze in conjunction with a colloid defoaming method, the colloid degassing method comprising: vacuum defoaming treatment of the colloid. During the vacuum defoaming process, the large-volume bubbles tend to accelerate and rise to the surface of the colloid to rupture. Although the small-volume bubbles can expand to a certain extent in a vacuum state, due to the high viscosity of the colloid, the small-volume bubbles are rising After reaching the surface of the colloid, it is not easy to break, which affects the degassing effect of vacuum degassing treatment.

[0027] The inventor has conducted research on the above colloid defoaming method, and through creative work, the inventor has noticed that heating the colloid before vacuum defoaming treatment is beneficial to improve the defoaming effect of vacuum defoaming treatment.

[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of t...

Abstract

The invention discloses a colloid defoaming method, a colloid defoaming device, a defoaming control system and a control method thereof. The colloid defoaming method comprises the following steps: heating colloid; carrying out vacuum defoaming treatment on the colloid subjected to the heating treatment; and carrying out cooling treatment on the colloid subjected to vacuum defoaming treatment. According to the invention, the defoaming efficiency is improved, and the defoaming effect is improved.

Description

technical field [0001] The invention relates to the technical field of colloid preparation, in particular to a colloid degassing method, a colloid degassing device, a degassing control system and a control method thereof. Background technique [0002] Various industrial colloids will produce certain bubbles during the preparation process. In order not to affect the use of the colloid, the air bubbles need to be removed. [0003] Usually, the methods for removing air bubbles in the colloid include: heating defoaming method, vacuum defoaming method and centrifugal defoaming method. The heating defoaming method is to heat the colloid, so that the bubbles float to the surface of the colloid and burst. The vacuum defoaming method is to vacuumize the chamber where the colloid is placed, and degas the colloid in a vacuum state. The centrifugal defoaming method is to use the colloid to be subjected to the centrifugal force when the colloid is rotating at a high speed, so that the...
