Description
技术领域technical field
本发明涉及一种哑光纸涂布用碳酸钙的制备方法。The invention relates to a preparation method of calcium carbonate for matte paper coating.
背景技术Background technique
碳酸钙是重要的无机化工产品，粒径一般小于2µm，常作填料。广泛应用于橡胶、塑料、涂料、造纸和油墨等作业，普通碳酸钙通常以石灰石为原料，经过煅烧制得生石灰，然后生石灰加水消化并吸收二氧化碳进行碳化，最后脱水、干燥得到产品。造纸行业中大量使用碳酸钙是基于国际上造纸工业从酸性造纸工艺转向碱性或中性造纸工艺，这样就可以大量使用廉价的碳酸钙代替以往的滑石和瓷土。造纸工业的这一重大技术转向，给PCC在造纸工业中的应用带来空前的增长机遇。Calcium carbonate is an important inorganic chemical product, the particle size is generally less than 2µm, and it is often used as a filler. Widely used in rubber, plastics, coatings, papermaking, ink and other operations. Ordinary calcium carbonate is usually made of limestone, which is calcined to produce quicklime. Then the quicklime is digested with water and carbon dioxide is absorbed for carbonization. Finally, it is dehydrated and dried to obtain the product. The extensive use of calcium carbonate in the paper industry is based on the fact that the international paper industry has shifted from an acidic papermaking process to an alkaline or neutral papermaking process, so that a large amount of cheap calcium carbonate can be used to replace the previous talc and china clay. This major technological shift in the paper industry has brought unprecedented growth opportunities for the application of PCC in the paper industry.
由于PCC 的不透光性能和对光的散射性能，使纸厂可生产出更高级别的不透光纸，PCC还具有比常规瓷土颜料高的光泽度，使用它可使纸品光泽度更高。光泽度高、不透明度性强对于纸张而言，从审美观点上看，对消费者有很强的吸引力。通常具有这种性能的纸品亦是高附加值的产品， PCC的高增量能力可使造纸厂在加工纸张过程中使用更多的填料，从而节省纸浆用量，降低成本。PCC作为造纸用填料，有以下优点:具有较高的不透光性和光泽度；作为填料，增量能力强；粒径保持均匀；颜色保持力强。Due to the opacity and light scattering properties of PCC, paper mills can produce higher-level opaque paper. PCC also has a higher gloss than conventional china clay pigments. Using it can make paper products more glossy. high. High gloss and strong opacity are very attractive to consumers from an aesthetic point of view for paper. Usually paper products with this performance are also high value-added products. The high incremental capacity of PCC enables paper mills to use more fillers in the process of paper processing, thereby saving pulp consumption and reducing costs. As a filler for papermaking, PCC has the following advantages: high opacity and gloss; as a filler, it has a strong incremental capacity; the particle size remains uniform; and the color retention is strong.

实施例1Example 1
将4吨长度为40µm碳酸钙晶须加入到4吨去离子水中，搅拌制成浆料，并向浆料中加入80kg聚丙烯酸钠分散剂，充分搅拌，使浆料获得良好的流动性。然后用泵将浆料送入三台串联的300升剥片机，用剥片机对碳酸钙晶进行研磨，研磨至其中小于2µm含量90%；制得哑光纸涂布用碳酸钙。Add 4 tons of calcium carbonate whiskers with a length of 40 μm to 4 tons of deionized water, stir to make a slurry, and add 80kg of sodium polyacrylate dispersant to the slurry, and stir well to make the slurry obtain good fluidity. Then use a pump to send the slurry into three 300-liter peeling machines connected in series, and use the peeling machine to grind the calcium carbonate crystals until the content of less than 2 μm is 90%; the calcium carbonate for matte paper coating is obtained.
