這樣做的主要是可以提升紙張的光澤度，以及改善紙張的透明度，得到更好的紙品，提升企業(yè)的經(jīng)濟(jì)效益。雖然這些都是經(jīng)過(guò)造紙消泡劑之后的過(guò)程或是結(jié)果，真正決定這些的則是在使用過(guò)程中的用法和用量。涂布工藝使用的成分包含顏料、膠粘劑和分散劑，潤(rùn)滑劑，消泡劑等，涂布消泡劑的使用一般在配置涂布涂料的過(guò)程中加入，制備銅版紙涂布涂料的膠乳主要是丁苯膠乳，在高速分散顏料或填料于其中時(shí)是很容易起泡的，這個(gè)時(shí)候就必須要使用造紙消泡劑，但是正常情況下的用量是在0.001-0.005左右的，如果本身涂布工藝過(guò)程中量比較大，造紙消泡劑也是需要進(jìn)行加量的，反之亦然，根據(jù)實(shí)際情況來(lái)決定消泡劑的用量。

　　在涂布過(guò)程中，用量固然重要，但怎么用也是重要的，首先根據(jù)實(shí)際泡沫情況，使用的造紙消泡劑是否需要進(jìn)行稀釋，因?yàn)橄♂尶隙〞?huì)降低消泡效果的，造紙消泡劑是直接可以使用的，如果需要稀釋的話要注意在使用攪拌，否則也是使消泡效果大打折扣的。

The main purpose of this is to improve the gloss of the paper, improve the transparency of the paper, get better paper products, and improve the economic benefits of the enterprise. Although these are the processes or results after the papermaking defoamer, what really determines these is the usage and dosage during use.

The components used in the coating process include pigments, adhesives and dispersants, lubricants, defoaming agents, etc. The use of coating defoaming agents is generally added in the process of configuring the coating coating. The latex for preparing the coated paper coating coating is mainly Styrene-butadiene latex is easy to foam when the pigments or fillers are dispersed at high speed. At this time, a papermaking defoamer must be used, but the dosage under normal circumstances is about 0.001-0.005. If the coating process itself In the process, the amount is relatively large, and the papermaking defoamer also needs to be added, and vice versa, the amount of defoamer is determined according to the actual situation.

In the coating process, the dosage is important, but how to use it is also important. First of all, according to the actual foam situation, whether the papermaking defoamer used needs to be diluted, because dilution will definitely reduce the defoaming effect, and the papermaking defoamer is directly It can be used, if you need to dilute it, you should pay attention to the use of stirring, otherwise the defoaming effect will be greatly reduced.
