​加填料的作用就是用填料填塞纖維間的縫隙,使錶面均勻,並加強柔韌性,減少紙的透明度和伸縮性,降低紙的生產成本及提高它的質量。紙張中所用的填料種類繁多,一般常用的填料有白土、滑石粉、碳酸鈣和硫酸鋇等。要求填料顆粒細、均勻、色相純白、無雜質、覆蓋能力強、化學性能穩定不易變質,且是不溶解或不易溶解於水的物質。

印刷紙張製造的第四步：加填和施膠

打漿結束前,還要在打漿機內進行加填和施膠等工作,也就是根據各種紙張的要求,在漿料內加入填料和膠料來改變紙張的某些性質。相互交織的纖維之間,不可避免地會形成許多空隙或孔眼,使紙張錶面凹凸不平。

加填料的作用就是用填料填塞纖維間的縫隙,使錶面均勻,並加強柔韌性,減少紙的透明度和伸縮性,降低紙的生產成本及提高它的質量。紙張中所用的填料種類繁多,一般常用的填料有白土、滑石粉、碳酸鈣和硫酸鋇等。要求填料顆粒細、均勻、色相純白、無雜質、覆蓋能力強、化學性能穩定不易變質,且是不溶解或不易溶解於水的物質。

含有纖維素的纖是親水物質,而且纖維與纖維之間的毛細孔具有吸水性,為此紙張中必須加入一種膠質物,從而塗塞纖維的錶面及纖維間的空隙,減少纖維間的吸濕性,並能改善紙張的強度,防止紙面起毛等,此種膠質物叫膠料。通常所用的膠料有松香、硫酸鋁、明礬、水玻璃和乾酪素。

印刷紙張製造的第四步：加填和施膠

這些膠料(除硫酸鋁外)最初以顆粒形態存在於纖維錶面或纖維之間,然後在成紙的過程中,遇熱熔化後成一層連續的或不連續的薄膜層。

這樣當紙面遇到極性的水時,保證了紙張具有一定的抗水性能。
