Description
混合工程は、上述のように調製した水酸化カルシウム含有水性懸濁液に熱処理によって得られた焼成物を加え、常温よりも高い温度、好適には50〜90℃、より好適には60〜80℃で混合し、一定時間熟成した後、炭酸化反応を行う。尚、水酸化カルシウム含有水性懸濁液の調製方法として湿式消化を採用する場合には、生石灰と上記焼成物を混合後に、若しくは、消化反応の進行過程で焼成物を添加し、消化時の発熱反応を利用して消化と熟成を同時に行ってもよい。 In the mixing step, the calcined product obtained by heat treatment is added to the calcium hydroxide-containing aqueous suspension prepared as described above, and the temperature is higher than room temperature, preferably 50 to 90 ° C, more preferably 60 to 80. After mixing at ° C and aging for a certain period of time, a carbonation reaction is carried out. When wet digestion is adopted as the method for preparing the calcium hydroxide-containing aqueous suspension , the calcined product is added after mixing the quicklime and the calcined product, or during the progress of the digestion reaction, and heat is generated during digestion. Digestion and aging may be carried out at the same time using the reaction.
尚、本発明の熱処理工程後に焼成物の分級を行った場合、特に液体サイクロンで行った場合には、炭酸化後工程として行う分級の負荷が少なく、例えばカットポイント20μｍ以上の液体サイクロンによる１段階の分級のみでもよい。炭酸化後得られるPCCの粒径が比較的大きい場合や粒径分布が広い場合には、複数段階で分級することが好ましい。これにより液体サイクロンの摩耗を防止し、交換頻度を少なくすることができる。例えば２段階で分級する場合、第１段階ではカットポイントが40〜50μｍの２液分離型サイクロンで40〜50μｍ以上の粒子を取り除き、更に第２段階でカットポイントが20μｍの２液分離型サイクロンで20μｍ以上の粒子を取り除く。 When the fired product is classified after the heat treatment step of the present invention, particularly when it is carried out with a liquid cyclone, the load of classification performed as the post-carbonation step is small, for example, one step using a liquid cyclone with a cut point of 20 μm or more. It may be only the classification of. When the particle size of PCC obtained after carbonation is relatively large or the particle size distribution is wide, it is preferable to classify in a plurality of steps. As a result, wear of the liquid cyclone can be prevented and the frequency of replacement can be reduced. For example, in the case of classification in two stages, in the first stage, particles of 40 to 50 μm or more are removed with a two-component separation type cyclone with a cut point of 40 to 50 μm, and in the second stage , a two-component separation type cyclone with a cut point of 20 μm is used. Remove particles larger than 20 μm.
上述した本発明の内填紙或いは塗工紙は、内填剤或いは塗工用顔料として通常の軽質炭酸カルシウムを用いた紙と比べても遜色のない白色度、不透明度、印刷適性を有する。また本発明の内填紙は、填料として嵩高いPCCを用いているので嵩高い（紙中の空隙が多い）内填紙とすることができ、これにより光の散乱が増し、紙の不透明度が向上する。またカレンダー処理によっても不透明度の低下が少ないので処理の効果がでやすい。更に抄紙の際にワイヤー摩耗を低減することができる。 The above-mentioned inner filling paper or coated paper of the present invention has whiteness, opacity, and printability comparable to those of paper using ordinary light calcium carbonate as an inner filling agent or a coating pigment. Further, since the inner filling paper of the present invention uses a bulky PCC as a filler, it can be a bulky inner filling paper (with many voids in the paper), which increases light scattering and makes the paper opaque. Is improved. In addition, the effect of the processing is easy to be obtained because the opacity is not reduced even by the calendar processing. Further, wire wear can be reduced during papermaking.
