| 1、比较烧结程度 1. Comparison of the degree of sintering 烧结程度越高的瓦越牢固。方法是听敲击的声音，敲击时的金属声越清脆瓦越好。国标的抗折强度为≥1020N，我厂的抗折强度为7280N(平均)。 The higher the sintering degree, the stronger the tiles. The method is to listen to the sound of the knocking, the more the metal sound when the knock is, the better the tile. GB bending strength is more than 1020N, I plant the bending strength of 7280N (average). 2、看裂釉 2. Look at the cracked glaze 琉璃瓦裂釉是一个普遍现象。裂釉的瓦冬天受冻后会出现釉层剥离脱落，因而失去光泽及防水性能。检查方法是看瓦的表面有无细如蛛丝的裂纹。在淋雨或浸水粘灰尘后更加明显。如能放在冰箱中则更加容易检查出来。明月建陶攻克了裂釉的难关，工艺与众不同，因此明月的琉璃瓦不裂釉。 Glaze glaze is a common phenomenon. When the glaze's tiles are frozen in winter, the glaze layer will be stripped and shedding, thus losing the gloss and waterproof properties. Inspection method is surface tile no cracks as fine as silk. It is more obvious in the rain or after the soaking and soaking. If you can put it in the refrigerator, it's easier to check it out. The capture of ceramic glaze cracking process difficulties, out of the ordinary, so the moon does not crack glaze tile. 3、看吸水率 3. See the water absorption rate 琉璃瓦吸水越少越好。吸水多的抗冻性能差。检查的方法是比较干的瓦与浸水的瓦的重量差额，就是水份。国标规定吸水率≤12.0%，明月琉璃瓦的吸水率３～5%，抗冻性能优良。 The less the water glaze is, the less the better. The high frost resistance of water absorption is poor. The method of checking is the difference between the weight of the dry tile and the submerged tile, that is, the water. GB bibulous rate is less than 12%, 3 ~ 5% water moon glazed tile rate, good frost resistance. 4、看外观 4. Look at the appearance 外观主要看釉色的一致性，(国标规定3米距离目视无色差），平整度，表面的光泽，光滑程度，背面烧结的程度，厂牌商标等。琉璃瓦可选用大青、二青、缸土、碱土、紫砂，木节等软硬质原料及废匣钵粉、瓷粉等原料。另外，也可用部分采用煤矸石、煤研灰等矿物废渣、工业副产品来降低生产成本，也获得满意效果。 A consistent look mainly depends on the glaze color (GB, 3 meters from the visual achromatic), flatness, surface gloss, smoothness, back sintering degree, trademarks etc.. The blue glazed tile, two green, purple soil, alkaline earth, cylinder, a soft hard raw material and waste seggar powder, porcelain powder and other raw materials. In addition, it can also use coal gangue, coal grind ash and other mineral residue, industrial by-products to reduce production costs, and also obtain satisfactory results. |
