无机非金属抗裂处理方法及利用该方法进行处理的器 技术领域 本发明涉及一种无机非金属抗裂处理方法及利用该方法进行处理的 无机非金属器皿， 特别是经过处理后无机非金属体与金属体结合成一体 的用于盛装物品及用于烧、 烤、 炖、 煮的器皿， 本发明的处理方法及器 皿属于日用器皿加工技术领域。 背景技术 现有技术中， 用岩石及陶瓷、 泥、 沙等无机非金属制作的器亚具有 抗氧化、 抗酸碱腐蚀、 耐高温等许多优点， 因此， 一直为人们所喜爱。 如今， 在日常生活中， 日用器 ^餐具使用量最大。 如炊具中中国人使用 的沙锅、 陶锅， 日本、 韩国人用的石头锅、 碗、 烤盘等。 但目前常规技 术生产的石、 陶、 泥、 沙锅等器 ， 存在的最大问题是因上述非金属材 料质脆， 经不起冷热冲击， 因此存在易碰撞破碎， 易开裂的缺点， 特别 是制成烧烤型锅 （盘） 时， 开裂的现象尤为严重。
为了解决上述问题， 韩国发明人用热溶化后的铝金属， 在石锅、 石 烤盘的外体进行浇铸， 使之成为一个由铝金属包合的石锅、 石烤盘。 虽 然此技术方案可行， 但存在的缺点是： 1、 成本高。 因为石锅、 石烤盘的 石体需要加热后方能浇铸， 否则出现浇铸缺陷， 因此部分石体在浇铸加 热时出现了开裂现象。 2、 材料选择面窄。 只能选择耐温、 耐裂型石材方 能使用，普通石料无法进行制作。 专利号为 ZL03214643. 4的中国专利提 出 "在石头锅体（1 )的外面套有一与锅体形状相吻合， 并与之固为一体 的金属外壳（2 )，，。 该专利将溶化后的金属 "在石头锅体外加上一定厚度 的金属， 再车削加工成光滑美观的金属外壳" 是可以实现的。 若用 "直 接加工出金属外壳 （2 )再将它与加工出的石头锅体（1 )结合为一体" 的方式， 由于这种提法只是一种设想， 并未给出具体的实施方案， 以做 到石锅体与金属外壳二者相吻合。 若用普通技术实施这一方案， 因在二 者的公差配合及加工制作上难度很大， 加工成本也十分昂贵， 特别是石 头制品的加工， 目前 [艮难保证加工精度， 若石头锅体尺寸大于金属外壳 是无法进入到紧密贴合的金属外壳内的， 若石头锅体小于金属外壳， 则 不能做到相吻合， 二者也不可能做到固为一体。 正是由于上述原因， 国 内外至今无法实现 "直接加工出金属外壳（2 )再将其与加工出的石头锅 体（ 1 )结合为一体"。 本人在专利号为 ZL200420006208. 6的中国专利中 提出 "以石、 陶、 泥、 沙制成的锅为内锅体（1 ), 在其外部用金属材料 制成一个金属壳体作为外锅体（ 2 ),其特征在于内锅体（ 1 )与外锅体（ 2 ) 之间留有平均距离为 0. 2mm- 15譲 的空隙， 在这个空隙中装有填充物 ( 3 )。，，。 该专利虽然实现一 "直接加工出金属外壳 （2 )， 再将它与加工 出的石头锅体（1 )结合为一体" 的石、 陶、 泥、 沙锅等产品， 在一定程 度上解决了无机非金属体防磁撞破碎问题， 但缺乏对无机非金属体的紧 固作用， 该产品在热温条件下使用仍旧会出现开裂现象。 发明内容 针对现有技术存在的上述问题， 本发明的首要目的在于提供一种能 够有效解决由石、 陶、 泥、 沙等无机非金属材料制成的器皿遇热温开裂 的技术难题，进一步的目的是提供一种采用本发明方法进行处理的器 。
为了达到上述目的， 本发明是这样实现的：
一种无机非金属抗裂处理方法， 具体为： 在非金属体上遇热温容易 开裂部位的外部设置一封闭环状的金属紧固圈， 所述金属紧固團常温下 的里口尺寸小于非金属体被紧固处的外围尺寸， 将所述金属紧固圈加热 并在高温状态下套装在非金属体上， 利用热胀冷缩原理使金属紧固圈对 非金属体上被紧固处施加紧合力，并与非金属体形成一紧固的整体结构。
优选地， 所述金属紧固圈可选用铜、 钢、 铝金属材料制成。
优选地， 所述非金属体为由硅酸盐材料烧制的陶、 瓷、 玻璃以及由 岩石制成的锅、 碗、 盘、 杯等器亚。
优选地， 所述器亚的横截面为圆形或矩形或多边形。
优选地， 所述金属紧固圈在向所述非金属体上套装时的加热温度不 低于套装后的整体结构使用时的最高温度。
一种利用上述无机非金属抗裂处理方法进行处理的器 J^, 该器 JUL为 焖烧锅， 由陶制非金属体和金属紧固圈构成， 其中， 所述非金属体为包 括锅底和侧壁的锅形， 所述金属紧固圈为形状与非金属体侧壁相配的筒 状， 其下沿带有向径向里侧延伸并与非金属体下表面相配的环状凸缘。
优选地， 所述金属紧固圈的上沿与所述非金属体侧壁的上沿齐平。 优选地， 所述金属紧固圈的上沿位于所述非金属体的底和侧壁的弯 角处， 并高于非金属体烕的上表面。
一种利用上述权利要求 1一 5所述无机非金属抗裂处理方法进行处理 的器 ，该器皿包括非金属体和金属紧固圈，所述非金属体由玻璃制成， 包括底和侧壁， 在所述非金属体的侧壁上间隔设置有若干个所述金属紧 固圈， 其中一个金属紧固圈位于非金属体侧壁的下部， 一个金属紧固圈 位于非金属体侧壁上部。
一种利用上述权利要求 1一 5所述无机非金属抗裂处理方法进行处理 的器 该器皿为烤盘， 由非金属体、 金属紧固圈、 夹板构成， 其中非 金属体为由石材制成的盘状， 所述金属紧固圈下沿与非金属体下表面齐 平， 金属紧固圈的上沿继续向上延伸构成烤盘的盘沿， 金属紧固圈与非 金属体上表面相对应处还设置有一下表面压靠在非金属体上表面上的环 状凸缘， 所述夹板靠压在非金属体的下表面上并与金属紧固圈的下沿相 连。
在以石、 陶、 泥、 沙等无机非金属材料制成的非金属体（1 )外部设 置一个金属紧固圈 （2 ), 这个金属紧固圈 （2 ) 与非金属体（1 ) 紧固处 的尺寸， 应小于等于零。 将这个金属紧固圈（ 2 )进行加热膨胀后套合在 非金属体（ 1 )的外部。 金属紧固圈 （ 2 )冷却后将非金属体（ 1 ) 緊紧地 包覆并聚合为一体。 金属紧固圈（2 )热膨胀尺寸与加热温度有关， 一般 加热到 30(TC - 800°C时， 以 200麵口径的金属紧固圈 （2 )为例在此温 度下能向外扩张 1 - 3麵左右， 这对于非金属体（ 1 ) 不需要十分精确的 加工精度， 对于陶瓷类制成的非金属体（ 1 )略有烧制变形也能使用， 金 属紧固圈（ 2 )加热软化后很容易将非金属体（ 1 )压入在金属紧固圈（ 2 ) 内。 对于金属紧固圈 （2 ) 与非金属体（1 ) 配合尺寸最好选用 0 - - 5隨 之间， 调节金属紧固圈 （2 ) 的加热温度就可以将金属紧固圈 （2 )套装 在非金属体（1 ) 的外部， 冷却后的金属紧固圈 （2 ) 以非常大的紧合力 固定套装在非金属体（ 1 )外部。 这种物理紧合力是一种强大聚合力， 能 使非金属体（ 1 )在使用受热时产生的膨胀力不向外扩张， 以保证非金属 体（ 1 )遇热时不再开裂。 这样要求无机非金属体（ 1 )与金属紧固圈（ 2 ) 不仅仅是吻合相贴， 而是要求金属紧固圈 （2 )还应具有一定的紧合力。
当然， 这种紧合力的大小， 对于非金属体（ 1 )的抗裂性能有重要影 响， 紧合力过小起不到限制膨胀的作用， 无机非金属体（ 1 )仍旧有开裂 现象。 因此， 对于金属紧固圈（2 )的材廢、 厚度及套装时的加热温度壳 根据非金属体（1 ) 的材质、 厚度作一定的调整。 金属紧固圈 （2 )选用 的材料， 如钢、 铁、 不锈钢、 铝其厚度不低于 0. 2mm， 套装时所需要的 加热温度应在 50°C一 1200°C , 只有这样才能有效地保证加工的产品具有 可靠的抗裂性能。
需要指出的是， 上述预制的金属紧固圈为封闭环形； 本发明中的非 金属体可以是断面为圆形的回转体形状， 也可以是断面为矩形或多边形 的非回转体形状。 由于金属紧固圈受热后不但膨胀而且软化， 因此对于 非回转体形状的器 , 金属紧固圏仍然能够很好地紧密套装并与之聚合 成一整体。
本发明与已有技术相比， 由于采用了金属紧固圈（2 )加热套装在非 金属体（1 )的工艺方法, 使二者的公差配合空间很大， 它能经济可靠地 将金属紧固圈（2 )与非金属体（1 )结合为一体， 并通过金属紧固圈（2 ) 有效的强化了非金属体（1 )的抗裂、 抗碰撞性能， 极大的提高了传统无 机非金属体的质脆、 不耐热冲击性能， 扩展了其使用范围。 并且用该技 术可以低成本生产出玻璃、 陶瓷、 石头等非金属材料制作的抗裂、 耐冷 热冲击的新型器亚。 附图说明 下面结合附图对本发明进行详细说明。

图 4为本发明实施例 3的结构示意图。 具体实施方式 附图中序号 1为非金属体， 序号 2为金属紧固圏， 序号 3为金属压 板。
实施例 1为一种经过无机非金属抗裂处理的焖烧锅。
下面结合图 1详细说明依据本发明提出的具体结构细节及使用情况。 本实施例 1的非金属体 1是一个直径为 240mm, 高度为 100mm, 由陶 土材料烧制而成的焖烧锅， 这种锅型主要是为了炖、 煮食物用的。 在非 金属体 1外部的金属紧固圈 2是用厚度为 0. 25 - 0. 5麵冷轧钢板模压成 型， 这个金属紧固圈 2的高度也在 100瞧左右， 类似一个金属外壳， 其 直径在 239隨为宜， 金属紧固圈 2的下沿带有向径向里侧延伸的环状凸 缘 21。 将这个金属紧固圈 2进炉加热温度到 800 °C左右， 金属紧固圈 1 由于受热膨胀， 此时能将非金属体 1套入在金属紧固圈 2内， 由于金属 紧固圈 2壁薄， 虽然温度很高， 但热温蓄量不足以让非金属体 1遇热温 开裂时， 金属紧固圈 2已开始冷却收缩， 对非金属体 1产生了紧固聚合 作用。 当金属紧固圈 2完全冷却后， 它与非金属体 1紧固成一个坚实的 整体结构， 这种利用材料的物理性能紧固的工艺方法， 能产生很强的聚 合力， 比用机械紧固工艺方法简单可靠。 较溶化金属浇铸工艺方法生产 成本低。 除此之外， 本工艺方法还具有以下两点突出的优点， 1、 若陶瓷 材料烧制的非金属体 1略有烧制变形时， 可将金属紧固圈 2在 800 °C温 度下， 使其材质已呈现软化状态， 再将非金属体 1 自由套入， 遇有困难 时可轻压非金属体 1 , 使软化状态的金属紧固圈 2 能产生与非金属体 1 相同的局部细微变形， 以便二者进行顺利密贴套合； 2、 金属紧固圈 2 是在较高温下如 500 - 800 °C温度下将非金属体自由套入或被压入非金 属体 1 , 因此该发明产品在燃气或电热源上使用时， 虽然非金属体 1及 金属紧固圈 2均有受热膨胀现象，但使用温度不超过套合装配时的温度， 金属紧固圈 2仍具有相当的紧合力，使非金属体 1没有向外开裂的空间， 具有了优异的防开裂性能。 上述优点均是采用机械和浇铸工艺方法无法 达到的。
本实施例 1中的非金属体（1 )也可采用石材、陶瓷及玻璃进行制作。 上述材料制品自身的遇温抗裂能力远不如陶土烧的陶制品， 所以金属紧 固圈 2的厚度应增加， 使其具有足够的强度， 以保证产品的抗裂性能。 本实施例中将金属紧固圈 2制成与当非金属体 1等高的型式后， 在 可有效防止非金属体 1遇热温开裂的同时， 金属紧固圈 2还具有防止非 金属体 1受到撞击后易破碎的功能。 本实施例中的金属紧固圈 2也可制 成如图 2中所示的结构， 其上沿低于非金属体 1的上沿。
如果仅仅为了防止非金属体 1遇热温开裂， 也可采用宽度与非金属 体 1底部厚度相当的金属紧固圈 2。
本实施例中的非金属体 1的横截面可为圆形， 也可制成多边形。 实施例 1为一种无机非金属抗裂处理的玻璃碗。
下面结合图 2详细说明依据本发明提出的具体机构细节及使用情况。 本实施例 2的非金属体 1釆用直径为 180mm高度为 80隱的玻璃进行 制作。 金属紧固圈 2采用厚度为 2. 5應、 宽度为 6誦的钢管制作三个圆 环状的金属紧固圈 2， 分别套在碗状非金属体 1上、 中、 下三个部位上， 其中底部金属金属紧固圈 2的下沿与非金属体 1的下表面齐平。 金属紧 固圈 2与非金属体 1相贴紧固处配合应为 -0. 5麵 - - 1. 2mm之间为宜。将 金属紧固圈 2进行加热， 此时金属紧固圈 2开始遇热膨胀， 当温度达到 60CTC时，金属紧固圈 2的内径尺寸比原尺寸增大 2匪左右，此时可轻松 地分别将各金属紧固圈 2套在非金属体 1的被紧固处。 为了減少金属紧 固圈 2的热温量过大对非金属体 1产生不利的影响， （非金属体 1遇高温 开裂）应采用溅水降温的方法， 将水浇注在金属紧固圈 2外使其迅速冷 却， 金属紧固圈 2能在短时间内将非金属体 1快速紧固， 此方法对紧固 玻璃、 瓷器这些遇温易开裂、 破碎的材料制成的非金属体 1十分有效。 本实施例也可制成杯类或壶类等抗裂型硅酸盐器 ^。
由于本实施例中的非金属体 1使用时通常不会直接在其底部进行加 热， 而是用于直接盛放温度较高的物质， 因此其上设置用了三个金属紧 固圈 2 , 这样可保证非金属体 1整体的遇热温抗裂性， 同时上边和中间 的金属紧固圈 2则还具有防碰撞破碎的功能。
实施例 3为一种无机非金属抗裂处理的石烤盘。
下面结合图 3详细说明依据本发明提出的具体结构细节及使用情况。 本实施例 3的非金属体 1采用的是花岗岩石板， 其厚度在 12nim， 直 径为 300mm的平面型圆盘。 金属紧固圈 2采用金属铝压铸成一个无底锅 的形状， 其总高度为 35麵， 其厚度为 3薩， 在其内径下部带有一个能装 入非金属体 1的圆口， 其内径尺寸小于非金属体（1 )外径 1讓为宜， 先 将这个无底锅状体的金属紧固圈 2进炉进行加热 400 - 500°C , 此时金属 紧固圈 2的圆口内径尺寸已膨胀至足以将非金属体 1装入在圆口内， 迅 速地将非金属体 1装入在金属紧固圈 2后， 注水冷却， 这个无底锅状的 金属紧固圈 1紧紧地与石制圆盘状的非金属体 1成为一个整体结构， 再 由金属压板 3通过螺钉将非金属体 1的底端面与金属紧固圈 2进行紧固， 制成为一种新式抗裂型石烤盘。 还应当说明的是由于铝金属材质较软， 在这种物理紧缩作用下， 二者之间接触面形成密贴结构不需要任何密封 物， 能形成一个不漏油， 不漏水的紧固整体。 这种工艺就其二者之间的 接触面的密贴程度优于用传统金属铝浇铸的方法。 具体表现为： 1、 非金 属体 1及金属紧固圈 2在冷态时， 金属紧固圈 2尺寸小于非金属体 1 , 当二者热膨胀后， 金属紧固圈 2内部仍具有很强的紧合力， 以调节二者 因使用受热时因膨胀系数不同造成的接触面开缝现象； 2、生产成本低于 传统金属铝浇铸工艺， 因为后者需要将非金属体 1加热后方能烧铸， 非 金属体 1加热时将产生很多废品 （加热时开裂）； 3、 选材广泛， 选材不 需要苛求耐温、 耐热的非金属材料， 即可生产出高品质的抗裂型非金属 器皿； 4、 因为本产品具有很强的坚固及抗裂性， 非金属体的壁可以釆用 薄壁型， 因而重量轻， 节约材料， 制作成锅类器亚时还具有升温快， 节 约时间和能源的优点。
在本实施例中， 将金属金属紧固圈 2制成宽度较大的型式后， 金属 紧固圈 2高出非金属体上表面的部分同时起到器 侧壁的功能， 如果仅 仅用于防止非金属体 1遇热温开裂， 金属紧固圈 2在保持下沿与非金属 体 1下表面齐平的状态下， 其宽度可与非金属体 1的厚度相当或略小。
本实施例中的金属紧固圈 2也可制成径向厚度较大的环状金属盘， 这时金属紧固圈 2在对非金属体 1进行紧固的同时， 其上表面与非金属 体 1上表面共同构成烤盘的上表面 （图中未示出）。
需要强调的是本实施例中的石烤盘可制成圆形或多边形或矩形等多 种形状。
