    环氧地坪国内溶剂型涂料短期内仍无可替代

    2018-10-29 08:53:41 无锡盛发地坪科技有限公司 阅读

    当前欧美发达国家对造船业使用的涂料有严格的VOC规定,相信不久的将来其他国家也会有更严格的规定。我国作为一个发展中国家,为了赶超世界先进水平,环氧地坪,走可持续发展的道路,避免少走先污染后治理的弯路,提高我们的环保要求,这一点在我国的"大气污染综合排放标准"中就有体现。溶剂类产品中,涂料和胶粘剂也是最重要的溶剂下游。常用溶剂:甲醛、丙酮、丁酮、乙醇、异丙醇、丁醇、丙醇、醋酸乙酯、醋酸丁酯、甲苯、二甲苯等有机溶剂。全世界和我国都在向无溶剂化方向努力。

    At present, the developed countries in Europe and America have strict VOC regulations on the coatings used in shipbuilding industry, and it is believed that other countries will have more stringent regulations in the near future. As a developing country, in order to catch up with the world's advanced level, epoxy floor, take the road of sustainable development, avoid the detour of pollution first and then control, improve our environmental protection requirements, which is reflected in our "comprehensive emission standards of air pollution". In solvents, coatings and adhesives are also the most important solvents downstream. Common solvents: formaldehyde, acetone, butanone, ethanol, isopropanol, butanol, propanol, ethyl acetate, butyl acetate, toluene, xylene and other organic solvents. The world and our country are striving towards solvation. 去溶剂化的优势

    首先政策导向,随着市场的发展,水性涂料和胶黏剂技术含量和环境友好的优势将充分发挥。环保成为百姓最关心的话题之一,受连年的雾霾天气加重影响,2014年将以前所未有的高度重视环保问题。具体到涂料化工行业中,环境友好型、资源节约型水性涂料是鼓励发展产品。汽车涂料水性化要达到70%,家具家装领域涂料水性化要达到30%。胶黏剂方面:无溶剂胶黏剂由于不含有机溶剂,所以不燃、不爆,运输便利,且储存安然。操作无溶剂胶黏剂复合的产物无残留溶剂,是以无毒、无害、无异味,卫赌气盼望能好。在生产作业中,没有溶剂开释到空气中,对独霸职员健康及景象都无风险。无溶剂复合设备没有干燥系统,能耗少。生产速度快,效率高。今朝世界上无溶剂复合的最高速度可达到480m/min而操作溶剂型胶黏剂的干式复合速度仅能达到其一半的程度。操作无溶剂胶黏剂综合成底蕴对较低。当然其采办单价较其他产物高些,但其上胶量少,仅胶黏剂用量便可俭仆30%~40%,综合本钱比溶剂型干式复合可降落50%以上。投资少,比操作溶剂型胶黏剂的干式复合设备,俭仆了约一半的投资。苏州环氧地坪

    First of all, policy-oriented, with the development of the market, water-based coatings and adhesives technology content and environmental friendly advantages will be brought into full play. Environmental protection has become one of the most concerned topics of the people. Affected by years of fog and haze, environmental protection will be given unprecedented attention in 2014. Specifically in the coating chemical industry, environmentally friendly, resource-saving water-based coatings are to encourage the development of products. The waterborne property of automotive coatings should reach 70%, and the waterborne coating of furniture and home furnishings should reach 30%. Adhesives: Solvent-free adhesives do not contain organic solvents, so non-flammable, non-explosive, convenient transportation, and safe storage. Solvent-free adhesive compound operation of the product without residual solvent, is non-toxic, harmless, odor-free, gambling gas hope to be good. In production operations, no solvent is released into the air, and there is no risk to the health and vision of the exclusive staff. The solventless composite equipment has no drying system and less energy consumption. The production speed is fast and the efficiency is high. Nowadays, the highest speed of solvent-free compounding in the world can reach 480 m/min, while the dry compounding speed of solvent-operated adhesives can only reach half of that. The operation of solvent free adhesives is less comprehensive. Of course, its unit price is higher than other products, but the amount of glue is less, only the amount of adhesive can be saved by 30%-40%, the overall cost can be reduced by more than 50% than the solvent-based dry composite. Less investment, more than half the investment in dry composite equipment than solvent based adhesives. Suzhou epoxy floor

    去溶剂化的瓶颈

    Solvation bottleneck

    溶剂型涂料依旧占据国内主导,水性涂料短期仍难以撼动油性涂料的市场地位。除市场认知度有限外,性价比以及企业转型成本也是阻碍其发展的重要因素。溶剂型涂料因其入行门槛相对较低,小规模油漆厂商数量众多。且经过长久以来的市场竞争磨合,使油漆价格处于市场竞争的优势。胶黏剂,尤其是对于刚刚引进无溶剂复合设备的软包装企业来说,苏州环氧地坪,其对无溶剂复合工艺的整个生产流程还处于熟悉、认知阶段。另一方面,在无溶剂化进程中许多技术尚未突破瓶颈,还有很多技术难题尚待解决。苏州环氧地坪

    Solvent-based coatings still dominate the domestic market, water-based coatings are still difficult to shake the market position of oil-based coatings in the short term. In addition to the limited market awareness, cost performance ratio and the cost of enterprise transformation are also important factors hindering its development. Because of its relatively low entry threshold, the number of small scale paint manufacturers is large. And after a long period of market competition, the price of paint is in the competitive edge of the market. Adhesives, especially for the soft packaging enterprises that have just introduced solvent-free composite equipment, Suzhou Epoxy Floor is still familiar with the whole production process of solvent-free composite technology. On the other hand, many technologies have not broken through the bottleneck in the process of solvent-free, and there are still many technical problems to be solved. Suzhou epoxy floor

    涂料和胶粘剂本身的特性正是溶剂型胶粘剂所占的巨大优势,而无溶剂的水性胶粘剂和涂料在这些方面的技术仍有待于公关。因此目前来看,从发展趋势而言更加环保的水性化无疑是未来的发展方向,但平衡产品本身的利弊来看,溶剂型依旧占据着市场的主要地位,甚至短期无可替代。因此虽然水性胶粘剂的比例正在逐年扩大,但胶粘剂总体产量仍在不断提升,传统溶剂型胶粘剂市场短期还难以撼动。

    The properties of coatings and adhesives themselves are the great advantages of solvent-based adhesives, and the technology of solvent-free water-based adhesives and coatings in these areas remains to be publicized. Therefore, at present, from the development trend, more environmentally friendly water is undoubtedly the future direction of development, but the balance of the advantages and disadvantages of the product itself, solvent-based still occupies the dominant position in the market, or even short-term irreplaceable. Therefore, although the proportion of water-based adhesives is expanding year by year, but the overall production of adhesives is still rising, the traditional solvent-based adhesives market is hard to shake in the short term.
