Nor could I pass unnoticed the suggestion of the bleak shores of Lapland, Siberia, Spitzbergen, Nova Zembla, Iceland, Greenland, with “the vast sweep of the Arctic Zone, and those forlorn regions of dreary space,—that reservoir of frost and snow, where firm fields of ice, the accumulation of centuries of winters, glazed in Alpine heights above heights, surround the pole, and concentre the multiplied rigours of extreme cold.” Of these death-white realms I formed an idea of my own: shadowy, like all the half-comprehended notions that float dim through children’s brains, but strangely impressive. The words in these introductory pages connected themselves with the succeeding vignettes, and gave significance to the rock standing up alone in a sea of billow and spray; to the broken boat stranded on a desolate coast; to the cold and ghastly moon glancing through bars of cloud at a wreck just sinking.
I cannot tell what sentiment haunted the quite solitary churchyard, with its inscribed headstone; its gate, its two trees, its low horizon, girdled by a broken wall, and its newly-risen crescent, attesting the hour of eventide.
The two ships becalmed on a torpid sea, I believed to be marine phantoms.
The fiend pinning down the thief’s pack behind him, I passed over quickly: it was an object of terror.
So was the black horned thing seated aloof on a rock, surveying a distant crowd surrounding a gallows.
彩石金属瓦、蛭石金属瓦、彩砂金属瓦的性能优势: 一、超强的耐候性彩石金属瓦、蛭石金属瓦、彩砂金属瓦是以高耐腐的镀铝锌钢板为基材,以高品质的水性丙烯酸树脂为粘合剂,以高耐候的天然彩石颗粒或无机颜料染色的天然石砾为层面,经特殊工艺加工制成的新一代金属屋面材料,是创新型、复合型、环保型高科技产品。这些材料都是高耐候的材料,使之在自然环境中具有超乎寻常的耐候性,它既是长期暴露于紫外线、湿气、热、寒和冲击下,仍然能保持颜色和物理性能的稳定性。 二、优异的耐腐蚀性能,高耐候性镀铝锌钢板具有非常好的耐腐蚀性能,不会被雨雪侵蚀导致性能下降,可长期地狱酸、碱、盐等多种化学物质的腐蚀,因此非常适用于盐雾腐蚀性强的沿海地区以及空气污染严重地区。 三、卓越的抗荷载性能,彩石金属瓦、蛭石金属瓦、彩砂金属瓦具有很好的抗荷载性能。 四、抗冲击耐低温效果好,彩石金属瓦、蛭石金属瓦、彩砂金属瓦具有良好的抗冲击低温能力,1公斤重钢锤1.5米高自由落在瓦面不产生裂纹,经过10个冻融循环,产品无空鼓、起泡、剥离、裂纹现象。 金属瓦是利用高耐腐的镀铝锌钢板与丙烯酸树脂经制板加压而成的屋顶材料,此外还有分别与这三种瓦配套的覆盖屋脊用的人字形背瓦。金属瓦的特点是单张面积大,有效利用面积大,还具有防火、防潮、防腐、耐热、耐寒、质轻等特性,而且制作生产简便,用途广。 我国屋面材料一般采用予制构件、钢筋混凝土、金属瓦、粘土瓦、彩色水泥瓦、水泥金属瓦等。钢筋混凝土由于成本高,一般作为高档工业厂房。住宅楼和民用悠久性房屋屋面材料;粘土瓦作为传统屋面材料,由于强度低、寿命短、吸水率高、生产时大量占用耕地、污染环境、浪费能源。国家已明令禁止生产使用。 金属瓦使用广泛,性能和价格比较其他屋面材料高,因而被广泛地作为一般工业、农业、国防、商业、民居及临时性建筑的屋面材料,特别是在多地震、多台风地区使用更为广泛。随着我国经济的迅猛发展,固定资产规模不断扩大,农业产业结构的调整,养殖业飞速发展,对金属瓦的需求增大。 目前,国家正在各地广泛推广节能建设,要求建筑工程必须采取节能设计标准,新建及改建建筑物一般采用外墙外保温设计方案。在城市规划区内,禁止建筑工程使用粘土砖等粘土类墙体材料,目前“禁粘”和节能建筑推广应用成效显着,新型墙材的总应用比例大幅上升。
