多跨或大跨度工业厂房天窗采光,采用屋顶平面采光较屋顶侧面采光好。但在以往的屋顶平面采光形式中,对防止直射阳光造成的眩光,防止冰雹、雨水,保温隔热,以及施工、维修等方面还存在一些问题。为了克服上述缺陷,又能保持平面采光的优点,我们试制成功了一种 P·V·B 涂料玻璃采光罩,并将这种采光罩在中州汽轮机厂各车间上安装使用。通过实验,现场测定和使用实践证明,这种采光罩是一种较好的采光形式。它是用聚乙烯醇缩丁醛塑料(简称 P·V·B),按一定比例溶于工业酒精,然后浇刮
Multi-span or large-span industrial plant skylight lighting, the use of flat roof lighting is better than the roof side lighting. However, in the past, flat roof lighting forms have some problems in preventing glare caused by direct sunlight, preventing hail, rain, thermal insulation, and construction and maintenance. In order to overcome the above defects and maintain the advantages of flat lighting, we successfully manufactured a P·V·B coated glass daylighting mask and installed it on each workshop of the Zhongzhou Steam Turbine Works. Through experiments, on-site determination and practice have proved that this kind of lighting mask is a better form of lighting. It is made of polyvinyl butyral plastic (abbreviated as P·V·B), dissolved in a certain proportion of industrial alcohol, and then poured
