Example Embodiment

[0016] The embodiment of the present invention aims to provide a device for reducing foam by directly spraying liquid onto the foam on the liquid surface to reduce the amount of foam, or by cooperating with the second container to transfer most of the foam to reduce the amount of foam. Therefore, the implementation of the present invention For example, to reduce the amount of foam, no defoamer can be used; but when there is too much foam, only a small amount of defoamer can be added to the second container to assist defoaming, which reduces the consumption of defoamer and saves costs.

[0017] Description will be given below in conjunction with the drawings and specific embodiments.

[0018] Such as figure 1 As shown, the device for reducing foam in the embodiment of the present invention includes a first container 11 containing foam, and a first spray pipe 12 is provided at the upper end of the first container 11.

[0019] In the embodiment of the present invention, the liquid s...

Abstract

The invention discloses a device and a method for reducing foam, relates to the technical field of foam treatment, and is invented for solving the problem that the prior art needs to add large amount of antifoaming agent to reduce the foam quantity. The device comprises a first container for accommodating the foam, and the upper end of the first container is provided with a first spray pipe. The method comprises liquid spray for the foam in the first container to reduce the foam quantity. The method and the device are free from using the antifoaming agent or using a small amount of antifoaming agent, save the production cost, reduce resource waste, improve the product quality, and can be applied in the field of production and manufacture of circuit boards.

Description

technical field [0001] The invention belongs to the technical field of foam treatment, in particular to a device and method for reducing foam. Background technique [0002] In the traditional PCB (Print Circuit Board, printed circuit board) production process, foam is very unfavorable to the production of PCB, which is mainly manifested in: 1. Waste of raw materials: due to foam, useful raw materials are lost The loss and the resulting waste are self-evident. 2. Prolonged reaction cycle: Because the chemical reaction products include gas and liquid, foam will cause gas retention, which prolongs the reaction cycle and consumes more power unnecessarily. 3. Affecting product quality: Due to the retention of air bubbles, many defects such as line gaps or residual copper appear in the finished product, resulting in a serious decline in product quality. 4. Pollution of the environment. Due to the overflow of foam, it will inevitably pollute the production environment and its sur...
