对于过去的东西不可能加以改变了,就因为它是过去的东西,对于现代的东西,我们必须承认其存在并发展它,对于未来呢-未来对于创造性地思想和行动是敞开大门的。——密斯粘土瓦的生产工艺与粘土砖相似,但对粘土的质量要求较高,如含杂质少,塑性高,泥料均化程度高等。中国目前生产的粘土瓦有小青瓦、脊瓦和平瓦。平瓦:长方形平面带沟槽的片状瓦,用于覆盖屋面。平瓦的成型有湿压法、半干压法和挤出法三种,以湿压法为最普遍,可烧成红、青两色。按中国标准规定:平瓦的尺寸为400×240-360×220mm,单片抗折荷载不得小于600 N;覆盖1m2屋面的瓦,其吸水后的重量不得超过55kg;在-15℃以下经冻融15次循环后,应无分层、开裂、脱边、掉角等现象,成品中不允许混有欠火瓦。
It is impossible to change the past because it is a thing of the past. For the modern, we must acknowledge its existence and develop it. For the future, the future is open to creative thought and action. - Mies clay tile production process and clay brick similar, but the higher quality of the clay, such as less impurities, high plasticity, high degree of homogenization of the mud. Clay tiles currently produced in China have small blue tiles, ridge tiles and flat tiles. Flat tiles: Rectangular flat trenched sheet shingles for covering roofing. Flat tile forming a wet pressure method, semi-dry pressing and extrusion three, to wet the most common method can be burned into red, green two colors. According to the Chinese standard, the size of flat tile is 400 × 240-360 × 220mm, the single piece of flexural load shall not be less than 600 N; the tile covering 1m2 roofing shall not exceed 55kg in weight after water absorption; Melting 15 cycles, there should be no delamination, cracking, off the edge, off angle and other phenomena, the finished product is not allowed to mix with owers watts.
