The product up to the standard is ensured by the inspection of the production process and the inspection before packing, shipments and transportation, respectively.

5、关键生产工艺介绍(Key Production Process) 1) AR 镀膜工艺介绍(AR Coating Process) 采用成熟的溶胶凝胶法,利用进口先进的辊涂设备,在光伏玻璃上表面均 匀涂上一层厚度约 110~140nm 有机纳米硅涂层,从而实现光伏玻璃降低反射率 的作用. 辊涂设备主要关键部件有压辊、涂布辊、网纹定量辊、托辊、消痕辊构成. 通过控制网纹辊目数、网纹辊和涂布辊间隙调节给液量,通过控制涂布辊速度 控制膜层厚度,通过调节涂布辊高度控制膜层均匀性和涂布压力. 中建材(合肥)新能源有限公司镀膜玻璃基本技术参数为:良好的亲水性 能和自洁性能、膜层厚度范围 110~140nm;

膜层折射率范围 1.31~1.36;

膜层硬 度范围 3~6H. In order to realize the reducing of the reflectivity for the photovoltaic glass, the ripe sol-gel method and advanced roller-coating equipment are applied, which coats a nano-organic silicon layer (thickness: 100~140nm) on upper surface of the photovoltaic. The major critical component of roller-coating equipment is made up of the pressurizing roller, coating roller, anilox quantitative roller, carrier roller and clear-trace roller. The flux of coating solution is adjusted by controlling the mesh number of anilox quantitative roller and the gap between the anilox quantitative roller and coating roller. The film thickness is adjusted by controlling the rotate speed of coating roller. The film uniformity and coating pressure are controlled by adjusting the height of coating roller.

5 The technical parameters of coating glass produced by China National Building Materials (Hefei) New Energy Resources Co. Ltd. are as follows: good hydrophilic, self-cleaning property, film thickness rang 110~140nm, film refractive index range 1.31~1.36, film hardness range 3~6H. 2) 玻璃钢化工艺介绍(Glass Tempering Process) 玻璃钢化方法主要有两种:化学钢化和物理钢化.化学钢化是将玻璃半成 品浸入到熔融钾盐中,玻璃表面与钾盐发生离子交换,使玻璃表面形成压应力 层,使玻璃表面具有较强的防划伤、提高玻璃表面硬度和防火防腐性能;

物理 钢化是将玻璃在加热炉内加热至玻璃转变点上 50℃,通过对玻璃的快速降温, 使表面质点来不及紧密排列,使冷却后的玻璃具有不均匀应力,从而使玻璃的 机械强度、耐火、耐腐蚀能力得到了提高. 中建材(合肥)新能源有限公司采用国产先进的节能光伏玻璃连续钢化炉, 对光伏玻璃进行强化加工,通过精密的 PID 温度控制方式,对钢化设备内进行 矩阵式紧密控制,将玻璃均匀加热至 610~640℃,在强度为 11000~17000Pa 冷 却风作用下进行强制冷却, 使玻璃内部应力在 89MPa 以上, 厚度为 3.2mm 以上 的玻璃冲击碎片在 50*50mm 范围内

40 颗以上. The methods of glass tempering include two types: chemical tempering and physical tempering. Chemical tempering is that raw glass is put into the molten sylvite, then ions exchange between glass surface and sylvite, which forms compressive surface stress layer on the glass surface, improving the scratch-proof intensity, the surface hardness and refractory corrosion resistance performance. Physical intensify is that the raw glass is heated above the glass transition point 50o C, then rapidly cools to make surface particle not to closely arrange, which makes the cooling glass own non-uniform stress, improving the mechanical intensity, refractory and corrosion resistance performance.

6 The photovoltaic glass is physically intensified by energy-savingly advanced continuous tempering furnace made in China. Matrix tightly controlling is realized by the way of precise PID temperature control. The glass is heated uniformly to 610~640o C, cooled forcibly under the effect of cooling air that the intensity is 11000~17000Pa. The tempered glass that internal stress is above 89MPa and thickness is above 3.2mm contains above

40 fragments in the range of 50*50mm when crushed.

s well-known that glass is fragile, and it'

s necessary to be stored and protected carefully. The standard condition for warehouse is to keep dry and clean where temperature and humidity don'

t change suddenly to avoid damp. The stack maximum is
