油墨公用纳米碳酸钙
重质碳酸钙简称重钙是由自然碳酸钙矿物如方解石、大理石磨碎而成。无毒、无安慰性、无味、色泽好、白度高，对其它颜色的干扰小，易着色、硬度低，对加工设施损轻，化学性稳固，属惰性填料，热合成温度为800 o C以上，易干燥，水分易除去，无结晶水，而且价钱昂贵。
四、用处：
重质碳酸钙可分为一般重质碳酸钙和超细重质碳酸钙等。重质碳酸钙通罕用作填料，还宽泛用于人造地砖、橡胶、塑料、造纸、涂料、油漆、油墨、电缆、修建用品、食品、医药、纺织、饲料、牙膏等日用化工行业，作填充剂起到添加产品的体积，升高消费老本。
①在橡胶中的使用
用于橡胶中，可添加橡胶的体积，改善橡胶的加工性，起半补强或补强作用，并可调理橡胶的硬度。
②在塑料中的使用
塑料工业是重质碳酸钙最大的生产畛域，细化的重钙粉，能显著进步塑料复合资料界面的强合强度及力学功能。塑料中应用微细重钙粉，既可升高其制作老本，又可进步和改其功能。
③在造纸中的使用
造纸工业用重质碳酸钙次要有两个用处，一是作为填料，二是作为涂层。目前，我国大少数造纸厂应用的是酸法造纸工艺，采纳的填料次要是高岭土和滑石粉，重钙会取代酸式施胶，重钙粉作为填料将在很大范畴内替代滑石粉或高岒土。
④在油漆、涂料中的使用
油漆、涂料也是重钙的次要生产畛域之一，普通是作为填料和体质颜料应用，次要使用的种类是修建涂料。在国外欧美等工业发达国度，胶粘剂也是重钙的次要生产畛域之一，但胶粉剂对重钙的要求较高，普通要求细度＞1250目.除此之外，粒度细、纯度高、白度好的重质碳酸钙还被使用在油墨、医药、化装品等畛域中。

Ink is special nanometer calcium carbonate
Heavy calcium carbonate or coarse whiting is made of natural calcium carbonate minerals such as calcite, marble ground. Non-toxic, without excitant, tasteless, good colour and lustre, high whiteness, small disturbance to the other color, easy coloring, hardness is low, the processing equipment damage of light, chemical stability, inert filler, the thermal decomposition temperature is above 800 o C, easily dry, easy to remove moisture, without water of crystallization, and the price is low.
Fourth, use:
And heavy calcium carbonate can be divided into ordinary calcium carbonate superfine heavy calcium carbonate, etc. Heavy calcium carbonate is usually used as a filler, but also widely used in artificial floor tile, rubber, plastic, papermaking, coating, paint, printing ink, cable, construction supplies, food, medicine, daily chemical industry such as textile, feed, toothpaste, as a filling agent rise to increase the volume of products, reduce the production cost.
(1) application in rubber
Used in rubber, can increase the volume of the rubber, to improve the rubber processability, half reinforcing or reinforcing effect, and can adjust the hardness of rubber.
(2) in the application of the plastic
Plastic industry is one of the largest consumption of heavy calcium carbonate, refining the coarse whiting powder, can obviously increase the plastic composites strong strength and mechanical properties of the interface. Plastic is used in fine coarse whiting powder, can reduce the manufacturing cost, but also improve and change its properties.
(3) application in papermaking
Papermaking industry with heavy calcium carbonate is mainly used for two purposes, one is as a filler, the second is as a coating. At present, the most paper mills are using acid method of papermaking process, USES the packing mainly kaolin and talcum powder, coarse whiting will replace acid type sizing, coarse whiting powder as a filler in large range instead of talcum powder or high 岒 soil.
(4) application in paint and coating
Paint, paint is also one of the main consumption of coarse whiting, is commonly used as a filler and extender pigment, is the main varieties of the architectural coatings. Europe and the United States and other developed countries abroad, adhesive is also one of the main consumption of coarse whiting, but the demand is higher, rubber powder of coarse whiting general requirements fineness > 1250 mesh. In addition, fine granularity, high purity and good whiteness of heavy calcium carbonate was also applied in printing ink, pharmaceutical, cosmetics and other fields.
