国际涂布化学品市场的现状与发展

文章从五个方面介绍全球涂布化学品的现状与发展,占造纸原料的8%为颜料和填料,而在占造纸原料1%的合成化学品中,涂布胶乳占到50%,其中又以SBR为主体,随着乳液聚合工艺水平的不断提高,人们已经从单纯的聚合方面来改进SB胶乳的质量,开始进一步考虑控制聚合的分子结构.涂布颜料仍以高岭土为主,但随着中性抄纸比例的不断提高,GCC和PCC的用量在逐年上升;因此,高岭土生产商开发出工程级产品以提高性能.北美市场涂布颜料中高岭土占主导地位,西欧以CaCO3为主.随着涂布纸质量要求及纸机车速的不断提高,在颜料制造商、胶乳生产商、涂布机供应商之间建立技术合作成为一种趋势,再加入油墨制造商和印刷商,这种不同领域、不同行业间的多元合作关系是实现涂布纸技术创新和发展的一个理想的解决问题的方案.

Present Situation and Development of International Market about Coating Chemicals

The paper from five aspects introduced global present situation and development about coating chemicals, among paper raw material pigment and filler takes 8%,synthetic chemical takes 1%,coating latex takes 50% while in synthetic chemical, its main body is SBR. Along with the technology of emulsion polymerization improved continuously, people not only boost the qualities of SB latex from polymerization, but also make further consideration to control the molecular structure on polymerization clay always is the main part of coating pigment, but following the percentage with neutral papermaking increased continuously, the use of GCC and PCC is increased year by year; then the clay producer develops engineering grade product to improve the performance. In North America clay is in the leading position of coating pigment market, in West Europe CaCO_3 is the main part. Following the improvement with quality and demand of coated paper and the raise speed of paper machine continuously, pigment manufacturer, latex producer, coating machine supplier, also ink manufacturer and print merchant may be technically cooperated each other, the trend has been establishing. The multiple cooperating between different field and different business is a good idea to solve the technical problem to bring the new idea in the technology and development of coated paper.
