摘要

石油化工行业是国家节能减排重点工程之一,如果相关设备设施保温不当,不仅会造成严重的热量散失,还会对油水分离和输送等产生影响。本文系统介绍了传统的以中空玻璃微珠或陶瓷微珠为主要隔热功能填料的隔热保温涂料的保温机理、性能及其存在的问题;以 SiO2气凝胶为主要功能填料的新型隔热保温涂料研究现状及研究中的技术难点;针对不同应用环境,开发兼具防腐、防开裂、隔热保温功能的复合保温结构设计。本文为研制新型耐高温、高效水性无机隔热保温涂料的研究提供了参考方向,为隔热保温涂料在石油化工领域的工程应用提供分析。

Abstract

The petrochemical industry is one of the most concerned areas of energy conservation and emission reduction projects. If the relevant equipment and facilities are not properly insulated,it will not only cause serious heat loss,but also affect the oil-water separation and transportation. This paper systematically described the heat preservation mechanism,performance and existing problems of the traditional thermal insulation coatings with hollow glass beads and ceramic beads as the main heat preservation functional filler,and also summarized the research status and technical difficulties of new thermal insulation coatings with SiO2 aerogel as main functional filler. Regarding different application environment,a compound thermal insulation structure with anti-corrosion,cracking resistance and heat insulation functions was suggested. This article would be used as a guide reference for the development of heat resistant and highly effective inorganic thermal insulation coatings system and application of thermal insulation coatings in petrochemical industry.
