(1)在不同生产工艺中，消泡剂的用法也有所区别，施工方法不同，用量也不

(1) in the different production processes, the use of antifoam is also somewhat different, different construction methods, dosage is not the same. Roll coating to be brought into air bubbles increases, it should be appropriate to add an antifoaming agent. <br>(2) compatibility problems. If the compatibility of the anti-foaming agent and the system is poor, there will be muddy, floating, or even change the color, adhesion between the layers will also be affected. <br>Front (3) Stir. Because the defoaming agent are several different nature and role of a mixture of easily separated. <br>(4) the effect of temperature. In the synthesis phase of the resin should be used in high temperature defoamers, there would defoamer emulsion breaking, losing defoaming effect. <br>(5) Effect of pH. Acid and alkali in the system, if a silicone defoaming agent, will have serious breaking. <br>(6) try to use manufacturers of the products, the firm has its own production centers and technical support, guaranteed stability between batches. <br>(7) give more consideration to the negative impact.

1 In different production processes, the use of defoaming agent is also different, construction methods are different, the dosage is not the same. When the roller sedits, to bring air, bubbles increase, should be appropriate to add more defoaming agent.<br>(2) Compatibility issues. If the antifoaming agent and the system's compatibility is poor, there will be turbid, floating, and even color changes, the interlayer adhesion will also be affected.<br>(3) Stir evenly before use. Because the defoamer is a mixture of several different properties and effects, it is easy to layer.<br>(4) The effect of temperature. In the synthesis stage of resin, high temperature defoaming agent should be selected, otherwise there will be defoaming agent, loss of defoaming effect.<br>(5) The effect of pH. In the strong acid and alkali system, if the silicone defoaming agent, will produce serious milk breaking.<br>(6) try to choose the products of large factories, large factories have their own production centers and technical support, the stability between the batches is guaranteed.<br>(7) Consider the negative effects.

(1) in different production processes, the usage of defoamer is also different, the construction methods are different, and the dosage is also different. When roller coating, air should be brought in and more bubbles should be added properly.<br>(2) compatibility. If the compatibility between defoamer and system is poor, turbidity, floating, even color change will occur, and the adhesion between layers will be affected.<br>(3) mix evenly before use. Because defoamer is a mixture of several different properties and functions, it is easy to layer.<br>(4) the influence of temperature. In the synthesis stage of the resin, high temperature defoamer should be selected, otherwise the defoamer will break the emulsion and lose the defoaming effect.<br>(5) the influence of pH value. In the strong acid and strong base system, if organosilicon defoamer is used, serious demulsification will occur.<br>(6) try to select products from large factories. Large factories have their own production centers and technical support, and the stability between batches is guaranteed.<br>(7) consider more negative effects.<br>
