本発明は、せつこう型の色分け、せつこう型の製作過程
における型分離性の判断等のために、微粒子状ｒｎ料で
せっこうを着色する方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for coloring plaster with a fine particulate RN material in order to color code plaster molds, judge mold separability in the manufacturing process of plaster molds, etc. Regarding how to.
従来、顔料の粉末をそのまませつこうに混入していた。 Previously, pigment powder was mixed directly into plaster.
しかし、微粒子どうしの混合のために顔料の分散性が悪
く、均一混合に長時間を要したり、色ムラが生じやすい
欠点があった。However, due to the mixing of fine particles, the dispersibility of the pigment is poor, it takes a long time to mix uniformly, and color unevenness tends to occur.
本発明の目的は、せつこうと顔料の均一混合を短時間で
行え、かつ、色ムラが生じにくい、優れたせっこうの着
色方法を提供することにある。An object of the present invention is to provide an excellent method for coloring gypsum that can uniformly mix gypsum and pigment in a short time and that is less likely to cause color unevenness.
本発明の特徴手段は、微粒子状顔料を球状粒子の表面に
付着させ、その顔料付着の球状粒子をせつこうに混入す
ることにあり、その作用効果は次の通りである。The characteristic means of the present invention is to attach a fine particulate pigment to the surface of a spherical particle, and to mix the pigment-attached spherical particle into plaster, and its effects are as follows.
つまり、顔料を付着させた粒子は分散しやすい球形状で
あり、また、球状粒子は分散性の良い粒径に適宜選定で
きるから、球状粒子をせつこうに混入するに際して、短
時間に均一に球状粒子を混入でき、ひいては、球状粒子
犬々に付着させた微粒子状顔料を短時間で均一にせっこ
う中に分散させて混入できる。In other words, the particles to which the pigment is attached have a spherical shape that is easy to disperse, and the spherical particles can be appropriately selected to have a particle size that provides good dispersibility. Particles can be mixed in, and furthermore, the fine particulate pigment attached to the spherical particles can be uniformly dispersed and mixed into the gypsum in a short time.
その結果、せつこうと顔料の混合を作業能率良好にかつ
確実に均一に行え、色ムラの無い良質のせつこう型を容
易迅速に造れるようになった。As a result, plaster and pigment can be mixed reliably and uniformly with good working efficiency, and high-quality plaster molds with no color unevenness can be easily and quickly produced.

うを顔料（１）により色ムラの無い状態で着色する。Next, the spherical particles (2) to which the pigment (1) is attached are stirred and mixed with plaster to uniformly disperse it in the plaster, and the plaster is colored with the pigment (1) without any color unevenness.
顔料（１）のせつこうに対する混入割合は、０．１〜１
０％程度である。The mixing ratio of pigment (1) to plaster is 0.1 to 1
It is about 0%.
尚、せつこうに水を混合するタイミングは、球状粒子（
