自1986年11月开始,由化工部北京化工研究院总负责、青岛堡料异型材有限公司、济南市天桥钢塑门窗工业公司和北京环球设计工程公司协作进行攻关的国家“七·五”科技重点项目之一的“防腐蚀工业厂房用塑料窗”的研制成果,已于1990年12月15日在青岛市通过了由国家科委主持的技术鉴定。与会专家认为塑料窗自身具有较可靠的防腐蚀性能,所以防腐蚀工业厂房用塑料窗项目的完成,尤其是防腐蚀塑料窗五金件的问世,推动了塑料窗应
Since November 1986, the “7·5” technology of the country has been jointly researched by the Beijing Chemical Research Institute of the Ministry of Chemical Industry, Qingdao Fort Materials Profile Co., Ltd., Jinan Tianqiao Steel and Plastic Door and Window Industry Co., Ltd. and Beijing Global Design Engineering Co., Ltd. One of the key projects, the “Plastic Window for Anti-Corrosion Industrial Plants,” was approved by the State Science and Technology Commission in December 15, 1990. Experts at the meeting believed that the plastic window itself has relatively reliable anti-corrosion performance, so the completion of the anti-corrosion industrial plant plastic window project, especially the introduction of anti-corrosion plastic window hardware, has promoted the plastic window.
