| 在涂料生产中，不可避免的会使用大量的固体原料，约占其原料的30%左右，且品种多样，常用的有气相二氧化硅、消光粉、钛白粉、炭黑、颜料、氧化锌、碳酸钙、膨润土、滑石粉等。其中产生的粉尘污染也是种类较多，有极大危害工人的身体健康的呼吸性粉尘，有易燃易爆的爆炸性粉尘，有无机也有有机粉尘。随着国内涂料工业的大规模发展，其粉尘污染带来的各方面的危害也不容忽视，需要建立一套可靠有效的防控措施来消除污染和降低危害。 Inevitably, a lot of solid materials will be used in coating production, which accounts for about 30% of its raw materials and varieties. There are commonly used fumed silica, matting powder, titanium dioxide, carbon black, pigment, Zinc Oxide, calcium carbonate, bentonite, talcum powder and so on. Among them, dust pollution is also a kind of respirable dust, which has great health hazards to workers. It has flammable and explosive dust, inorganic and organic dust. With the large-scale development of the domestic coatings industry, the harm caused by the dust pollution can not be ignored. It is necessary to establish a reliable and effective prevention and control measures to eliminate pollution and reduce hazards. 气相二氧化硅作为涂料的触变剂和增稠剂，防沉淀剂、防流挂剂，相信各位涂料朋友都会有用到，其粒径很小，比表面积大，表面吸附力强，气相二氧化硅以其优越的稳定性、补强性、增稠性和触变性，在众多学科及领域内独具特性，有着不可取代的作用。 Fumed silica as thixotropic agent coating and thickening agent, anti settling agent, anti sagging agent, believe that friends will be useful to the coating, the particle size is very small, large specific surface area, surface adsorption ability, fumed silica with superior stability, reinforcing, thickening and thixotropy, unique characteristics in many disciplines and fields, has an irreplaceable role. 但是也因为其粒径很小，难分散，粉尘污染让众多企业很是头痛。 But also because its size is very small, it is difficult to disperse, and dust pollution makes many enterprises have a headache. 特别是分散问题！目前，国内产品质量较好的企业使用的分散方式主要采取一步法的高速剪切分散，能基本满足用户的需要。但有相当多的中小企业分散设备还比较落后，分散时根本形成不了剪切力，只是一种搅拌，气相二氧化硅在树脂中根本形成不了网状结构，从而无法发挥材料的性能。 Especially the problem of dispersing! At present, the enterprises with better quality of domestic products use the one step method of high-speed shearing dispersion, which can basically meet the needs of the users. But there are quite a lot of small and medium-sized enterprises scattered equipment is still relatively backward. When dispersing, there is no shear force at all. It is just a kind of agitation, and fumed silica cannot form a mesh structure in resin, so that it can't play the material performance. 今天给各位涂料朋友带来这款材料，帮助各位解决分散和粉尘污染问题！ This material is brought to all of your friends today to help you solve the problem of dispersion and dust pollution! |
