PVC门窗在我国开发较晚,近几年来对其研制和生产有了很大的进展。化工部北京化工研究院在开发研制方面取得的成果PVC(BH～Ⅱ型)窗巳于1984年11月进行了技术鉴定,並在建筑工程中施工应用。就PVC材料而言,在建筑安装领域中应用较早,化工部第十二化工建设公司曾于1965～1965年施工安装过石家庄化肥厂百米高硬PVC排气筒和PVC衬里硝酸储罐等项工程,节约了大量当时较为昂贵的不锈钢材,取得较
PVC doors and windows have been developed late in China. Great progress has been made in the development and production of PVC windows and doors in recent years. Achievements in the development of the Beijing Chemical Research Institute of the Ministry of Chemical Industry The PVC (BH-II) window cassette was technically appraised in November 1984 and was applied in construction projects. As far as PVC materials are concerned, it was applied earlier in the field of construction and installation. The Twelfth Chemical Construction Company of the Ministry of Chemical Industry had constructed and installed the Shimuzhuang Fertilizer Plant 100m high PVC hard exhaust pipe and PVC lining nitric acid storage tank from 1965 to 1965. The project saved a lot of the more expensive stainless steel at that time and achieved better results.
