[D] 本发明一种用于玻璃工艺的冷却部区域的防析晶装置和防析晶工艺方 法, 权利要求的技术方案, 包括在冷却部中玻璃液的深度为 0.15M~0.9M; 按 所有冷却部玻璃液的平面面积计算, 每 0.2平方米一 2平方米范围安装了 1一 5 个加热装置和 1一 5个测温装置, 其安装在冷却部中玻璃液的底部到液面的范围 内; 形成密集网状的加热装置的特征;
当玻璃液平面线出现上升和下降变化时, 使玻璃液平面线也出现不同程度 的上升和下降变化, 或冷却部玻璃液量变化时; 尤其产生较大故障, 或成型工 段上因维护或操作失误、 或成型部产生故障或者更换产品、 或者进行成型工艺 中变化拉引量、 变化产品厚薄等调试时、 或玻璃的成型工序产生故障、 或退火 工序产生故障、 或切材工序产生故障、 或装包工序产生故障、 或要在不放玻璃 液进行维修等 13类大生产中不可避免的工艺状态, 必须关闭冷却部装置尾部的 安全闸板时, 这时的工艺控制程序设计为; 当测温装置测得温度低于玻璃液的 析晶温度 50°C时, 加热装置开始加热, 尤其要加大加热装置功率; 当测温装置 测得温度高于玻璃液的析晶温度 100Ό时, 加热装置停止加热。
由于在冷却部中玻璃液的深度为 0.15M— 0.9M; 按冷却部玻璃液的平面面 积计算, 在冷却部中玻璃液的底部到液面的所有范围内, 每 0.2平方米一 2平方 米范围安装了 1一 5个加热装置和 1一 5个测温装置, 形成密集的加热装置的特 征; 并且这时的工艺控制程序设计为加热装置功率要设置为所有加热装置的功 率高于正常大生产时的 3— 15倍, 尤其加大了加热装置功率后形成了每对电极 之间的相对方向的玻璃液热流动传导, 来保障冷却部从玻璃液的底部到液面上 的所有范围中, 的温度始终高于析晶温度 50°C以上, 具备完全不析晶的技术效 果;
[3]尤其本发明一种用于玻璃工艺的冷却部区域的防析晶装置和防析晶工 艺方法, 权利要求的创新技术方案中其装置结抅及功能与位置, 在出现以下大 生产中不可避免的工艺状态时出现的技术难题, 上述先有技术 1、 2、 3、 4、 5、 6、 7、 8技术方案是解决不了的; 本发明权利要求的创新技术方案产生的技术效 果, 是不可能被上述先有技术替代的。
其 1, 是因为在有不断的 145说0— 1540°C或以上的高温玻璃液从溶化部进入 时, 玻璃液是较快的在冷却部向成型部月 9流动; 而现有技术 4、 5、 6技术方案设 书
计的冷却部的某局部区域的电极为加热装置, 目的也是正常生产时, 是以防局 冷却部的某局部区域冷却太快而产生析晶; 并因成本原因, 选用的都是小功率 的加热装置钼电极; 而且现有一切浮法工艺都不在冷却部的玻璃液中安装加热 电极装置;
其 2, 是因为绝大多数生产线都不会采用成本高若干倍的锡电极, 而釆用 成本合适的钼电极为加热装置, 尤其冷却部已紧靠近成型部, 采用高的电流强 度易于会使钼电极分解而产生气体, 大生产时会使玻璃产品出现严重的气泡缺 陷;
其 3, 是因为在一切冷却部所设计的在正常连续大生产时, 上下及四边耐 火材料功能, 都为了大量散热的条件而设计的;
其 4, 是因为关闭冷却部装置尾部的安全闸板后, 就没有从溶化部源源不 断的 1450— 1540Ό或以上的玻璃液提供的基础性保障高温玻璃液进入, 就没有 玻璃液是较快的在冷却部流动向成型部的工艺条件;
可见, 在没有了基础性不断的 1450— 1540°C或以上的高温玻璃液从溶化部 进入时; 在没有了玻璃液是较快的从冷却部向成型部流动的热能流动传导状态 时; 又因上下及四边耐火材料具有大量散热功能时:
如果只靠现有技术的 4、 5、 6技术方案的冷却部的某局部区域的、 少量的、 小功率的、 加热装置, 根本无法加热到高于玻璃液的析晶温度 50°C ; 更根本无 法形成整个冷却部的玻璃液的热能流动传导状态, 来保障整个冷却部的玻璃液 加热到高于玻璃液的析晶温度 50Ό和长期的保温到高于玻璃液的析晶温度 50 。C ; 所以靠现有技术的 4、 5、 6技术方案, 在关闭冷却部装置尾部的安全闸板 时, 在生产这类特定成分的玻璃在强析晶温度范围时 DSC曲线中结晶峰尖锐, 玻璃从液态向析晶失透转化时间短并速度快, 但是又具有多种优秀特征的优秀 玻璃材料时, 一定会使整个冷却部玻璃液几个小时全部析晶固化, 使冷却部被 破坏而停产大修, 是个大的技术难题; 而按本发明一种用于玻璃工艺的冷却部区域的防析晶装置和防析晶工艺方 法权利要求的创新技术方案, 在关闭冷却部装置尾部的安全闸板时, 在生产这
类特定成分的玻璃在强析晶温度范围时 DSC曲线中结晶峰尖锐, 玻璃从液态向

析晶失透转化时间短并速度快, 但是又具有多种优秀特征的优秀玻璃材料时:
其一, 按本发明权利要求的创新技术方案, 在冷却部中玻璃液的深度为 0.15M— 0.9M、 按冷却部玻璃液的平面面积计算, 每 0.2平方米一 2平方米范围 安装了 1一 5个加热装置和 1一 5个测温装置、 加热装置和测温装置安装在冷却 部中玻璃液的底部到液面上的范围中; 形成密集的加热装置; 并且这时的工艺 控制程序设计为加热装置功率要设置为所有加热装置的功率高于正常大生产时 的 3— 15倍; 其二, 并且这时的工艺控制程序设计为加热装置功率要设置为所 有加热装置的功率高于正常大生产时的 3— 15倍; 就可克服整个冷却部玻璃液 几个小时全部析晶固化, 使冷却部被破坏而停产大修的技术难题; 就能达到克 服这类在强析晶温度范围时 DSC曲线中结晶峰尖锐, 玻璃从液态向析晶失透转 化时间短并速度快的特征的平板玻璃材料的缺陷的一面的技术效果; 又能达到, 使其各种上述优秀的材料性质特征能转变成大生产平板玻璃的产品的技术效 果;

[3]、 来保障玻璃液的底部到液面上的所有范围中, 玻璃液的温度始终高 于析晶温度 50Ό以上, 具备完全不析晶的技术效果, 达到克服这类在强结晶温 度范围时 DSC曲线中结晶吸峯尖锐, 玻璃从液态向析晶失透转化时间短并速度 快的特征的玻璃材料的缺陷的一面的技术效果。
[4] 在生产这类特征的平板玻璃材料时, 能克服先有技术, 在大生产中不 可避免的 10种生产工艺原因必须关闭冷却部装置尾部的安全闸板时: 将没有从 溶化部源源不断的 1450— 1540 C或以上的高温玻璃液的进入所带来的温度基础 性保障, 因此会使冷却部玻璃液几个小时全部析晶固化, 会使冷却部装备会全 部破坏, 会造成全生产线停产的严重技术后果的难点问题;
4、从上述 5个实施例可见,只有通过前述的一种用于玻璃工艺的冷却部区 域的防析晶装置及工艺方法的技术方案, 才可使这类新功能性的有巅覆性明显 优势的玻璃材料, 在大生产中克服析晶失透转化时间短并速度快的缺陷的一面, 成为有巅覆性明显优势的产品: 具有低溶化粘度温度 、 低排气泡粘度温度、低 成型粘度温度特征, 从而产生节能技术效果和少气泡、 少非熔化碴点等产品品 质优势、 具有对高氧化铝含量又有低温共熔的高抗折强度特征、 还具有优秀热 膨胀系数性质特征、 具有优秀的耐磨特征的技术效果的, 使这类玻璃材料的玻 璃制品的巅覆性优势的技术效果成为现实。
5、如不采用前述的本发明一种用于玻璃工艺的冷却部区域的防析晶装置及 工艺方法的技术方案, 则不能在大生产中, 克服这类析晶失透转化时间短并速 度快的玻璃材料缺陷的一面, 不能使这类玻璃材料的玻璃制品的巅覆性优势的 技术效果成为现实。 所以本发明的创造性技术方案产生的防析晶的显而易见技 术效果, 才能使这类新功能性玻璃材料的巅覆性的上述优势变为产品大生产的 现实, 有显而易见技术效果。
6、 一种用于玻璃工艺的冷却部区域的防析晶装置和防析晶工艺方法, 揭示 了从来没有被现有技术公幵或揭示的 -
[1]在生产本发明限定成分的这类特征的玻璃材料时, 出现的技术难点, 而 这些技术难点是先有技术解决不了的;
[2]通过前述的一种用于玻璃工艺的冷却部区域的防析晶装置及工艺方法 说 明 书 技术方案, 能克服这些技术难点是先有技术解决不了的技术难点;
[3]能产生的预料不到的前述多种技术效果: [a]能克服位于冷却部靠池壁耐 火砖上粘附的玻璃液析晶, 出现大量失透的晶体块, 不断掉入冷却部玻璃液池 中, 流入成型部而造成玻璃产品中有大量析晶的失透的晶体块, 使品质完全不 合格的难点问题;
[b] 能克服先有技术, 在大生产中不可避免的 10种生产工艺原因必须关闭 冷却部装置尾部的安全闸板时: 将没有从溶化部源源不断的 1450— 154CTC或以 上的高温玻璃液的进入所带来的温度基础性保障, 因此会使冷却部玻璃液几个 小时全部析晶固化, 会使冷却部装备会全部破坏, 会造成全生产线停产的严重 技术后果的难点问题;
所以上述多种层次的技术效果, 也不是业内人士显而易见的; 也不是一种 事后认为的用简单的逻辑推理或者简单试验就可以得出的; 都是预料不到的效 果产生了的 "质"和 "量" 的变化, 本发明方案是非显而易见的, 具有突出的 实质性特点和显著的技术进步。
以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发 明的精神和原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发 明的保护范围之内。
