在“以农业为基础、工业为主导”发展国民经济总方针的指引下,为了支援农业大力开展科研工作,湖北建筑工业学院与湖北省英山县农业科学实验站协作,从1974年起,发扬“自力更生,艰苦奋斗”的精神,开始进行农用温室玻璃钢的试制工作,并于1975年2月建成了一座200平方米的玻璃钢温室,完成了春、秋两季水稻栽培试验,效果良好。试制成的玻璃钢是0.5～1毫米厚的透明卷材,它的导热系数为0.2千卡/米·时·℃,透光率86～88%,弯曲强度2500公斤/厘米~2。这种玻璃钢不怕碰撞,各项性能指标都大大优于6毫米厚的平板玻璃。根据水稻栽培试验结果,在条件相同的情况下,玻璃钢温室与玻璃温室比较,具有以下
Under the guideline of “taking agriculture as the basis and industry as the leading factor” as the guiding principle for the development of the national economy, in order to support agriculture vigorously, the Hubei Institute of Architecture and Construction cooperates with the Agricultural Science Experimental Station of the county of Yingshan in Hubei Province, starting from 1974 “Self-reliance, hard work,” the spirit of agricultural greenhouse glass began trial production work and in February 1975 built a 200 square meters of glass fiber reinforced plastic greenhouse, completed the spring and autumn rice cultivation trials, the effect is good. The trial-made FRP is a transparent membrane with a thickness of 0.5 to 1 mm. Its thermal conductivity is 0.2 kcal / m · h · ℃, the light transmittance is 86-88%, and the bending strength is 2500 kg / cm -2. This glass is not afraid of collision, the performance indicators are much better than the 6 mm thick glass. According to the rice cultivation test results, under the same conditions, the glass fiber reinforced plastic greenhouse and glass greenhouse, with the following
