附图说明
图 1为实施例一的一种炒锅形不锈钢本体结构示意图;
图 2为实施例二的一种不锈钢不粘锅的结构示意图。
图 3为实施例三的一种平板形不锈钢制件的结构示意图;
图 4为实施例四的一种具有不粘性表面的不锈钢防盗门的结构示意图。
具体实施方式
实施例一:
参见图 1所示, 本实施例所述的不锈钢本体 1为炒锅形, 所述不锈钢本体 1 的内表面均匀布满了圆弧形 ffl坑, 不锈钢本体 1 内表面的表面粗糙度为 Ι^1 ~ 2 μ m。
本实施例所述的不锈钢制件, 可以是单一不锈钢材料制成的本体, 也可以是 表面层为不锈钢材料, 芯层为铝或铜的复合材料制成的锅体。
本实施例对不锈钢本体的加工, 经过以下步骤:
抛光—喷丸—清洗—, 其中:
( 1 ) 抛光: 先对不锈钢本体 1的内表面进行镜面抛光处理, 使不锈钢本体内 表面的粗糙度在 RaO. 05 ~ 1 μ ηι之间。 通过对不锈钢本体 1 内表面的镜面抛光处 理, 可去除表面的氧化层和其他杂质, 保证其表面的清洁度。
( 2 ) 喷丸: 釆用玻璃珠对不锈钢本体 1的镜面抛光面进行喷丸, 使锅内表面 布满均匀的圆弧形 ffl坑, 使不锈钢本体内表面粗糙度为 Ι^1 ~ 2 μ ηι。 通常上述玻 璃珠粒度为 60 ~ 160目比较适宜。 本实施例中釆用 100 目玻璃珠进行喷丸处理, 经喷丸后不锈钢本体 1的内表面粗糙度为 Ral. 3 μ ηι, 使不锈钢本体表面的圆弧形 四坑的深度均匀一致, 突出不锈钢表面的金属质感。
由于以往工艺釆用的是金钢砂对不锈钢锅体进行表面粗糙化, 而金钢砂形状尖 锐而不规则, 在喷砂后, 使不锈钢锅体表面形成深浅不一的微小凹坑。 在清洗时, 无法彻底将微小四坑内的微颗粒杂质清除干净, 使后续喷涂不粘材料溶液后, 不 粘层无法与不锈钢锅体表面充分粘接, 造成不粘层易分层脱落。 而通过喷丸工序
可以使不锈钢本体 1的内表面获得一定的粗糙度, 进而可以使不锈钢体 1 内表面 得到强化, 从而可以改善不锈钢锅的机械性能, 有效提髙了不锈钢锅的抗疲劳性。 并且, 由于玻璃珠表面均匀光滑, 在进行喷丸处理时, 不会对不锈钢本体 1表面 造成损伤, 不会破坏不锈钢锅表面金属质感。 且使其表面上形成的四陷深度相同 的圆弧形四坑, 有利于在后续清洗工序中彻底清洗不锈钢本体 1表面, 从而可保 证不锈钢本体 1表面的清洁度, 有利于增加不锈钢本体 1与涂层之间的附着力和 结合力, 使不粘层 2与不锈钢本体 1粘接更牢固, 延长了不粘层的耐久性。
( 3 ) 清洗: 将经过喷丸处理的不锈钢本体 1用加热的挥发性有机溶剂做为清 洗剂进行清洗, 以清除表面的污物, 不仅可利用热量分解一些附着在其表面上的 油质, 保证炊具表面的洁净, 同时还可使清洗完成后有机溶剂快速挥发, 使其表 面不会结垢, 提髙不粘层 2与不锈钢本体 1的粘接强度, 保证锅表面的美观。 本 实施例中釆用的有机溶剂为三氯乙烯, 具体清洗工艺分为三步: 第一步为粗洗, 将待清洗的不锈钢锅本体浸入 50 ~ 70 °C的三氯乙烯中, 同时启动 28KHz的超声波 发生器, 由有机溶剂和超声波配合进行 2分钟的清洗。 第二步为精洗, 将经过粗 洗的不锈钢本体浸入 60 ~ 70 °C的三氯乙烯中, 同时启动 68KHz的超声波发生器, 持续清洗 2分钟。 第三步为蒸汽烘干, 利用 80 ~ 90 °C的三氯乙烯蒸汽吹扫 2分钟, 使粘附在不锈钢本体上的三氯乙烯挥发干净。
由于现有工艺釆用没有经过处理的硬质水对不锈钢炊具表面进行清洗, 在清 洗完成后, 不锈钢锅体表面易产生水垢, 从而影响不粘层与不锈钢锅体的粘接强 度。 而在本实施例中, 利用有机溶剂对不锈钢锅本体进行清洗, 由于有机溶剂具 有较大的挥发性, 这样在清洗完成后, 残留在不锈钢锅本体表面的清洗液可迅速 挥发且不会产生结垢现象, 从而有效保证不锈钢本体的表面清洁度。
当然也可釆用三氯乙烷等化学性能相似的挥发性溶剂做为清洗剂, 但由于不 锈钢炊具为金属材质, 三氯乙烯具有较强的金属脱脂功效, 因此, 本实施例的实 施方案为优选实施方式。
在本实施例中, 为降低清洗成本及提髙清洗效率, 所述的清洗是在超声波清 洗机内进行清洗, 由于现有技术釆用髙压水枪进行清洗, 容易留下清洗死角且易
受人工因素影响, 使清洗效果不能达到技术要求, 而本工艺釆用超声波清洗机进 行清洗, 这不仅可避免人工因素对清洗效果的影响, 且还不会留下清洗死角, 保 护不锈钢本体的清洗洁净。 超声波清洗机明显提髙了产品的清洗质量, 使产品品 质更加可靠。
实施例二:
参见图 2所示, 本实施例涉及一种不锈钢不粘锅, 该锅具有实施例一中的不 锈钢锅本体, 在其炒锅形不锈钢本体 1的内表面上附着有一烧结不粘层 2, 所述 烧结不粘层 2的厚度为 1 ~ 5 μ ηι。 该烧结不粘层 2的材料含有氧化硅, 该烧结不 粘层 2由喷涂透明不粘材料溶液之后通过烧结与不锈钢本体 1表面粘接形成。
本实施例所述的不锈钢不粘锅的加工工艺是在实施例一步骤的基础上再进行 喷涂、 烧结处理。
( 4 )喷涂: 将透明不粘材料溶液均匀地喷涂于不锈钢本体 1的内表面上, 通 过喷涂使透明不粘材料溶液均匀地覆盖不锈钢本体表面的圆弧形四坑, 不粘材料 溶液的喷涂量, 应当以烧结后形成的不粘层的厚度 1 ~ 5 μ ηι为宜。 由于氧化硅具 有三维网状结构, 在不粘材料溶液中掺入氧化硅, 这样就可使不粘材料溶液干燥 时能在不锈钢本体 1表面形成网状结构, 从而提髙不粘层 2与不锈钢本体 1之间 的粘接强度和不粘层的光洁度。
( 5 ) 烧结: 将喷涂有透明不粘材料溶液的不锈钢锅放入烤炉内烧结 10 ~ 25分 钟, 烧结温度 200 ~ 28(TC, 通过烧结使喷涂于不锈钢本体 1表面上的不粘材料溶液 形成不粘层 2, 并完成具有不粘性表面的不锈钢锅的加工。 本实施例中, 烧结时间为 20分钟, 烧结温度控制在 230°C。
由上述工艺制成的具有不粘性表面的不锈钢锅, 表面强度髙, 不粘层 2与不锈钢本 体 1的结合牢固, 增加不锈钢锅表面耐蚀性和耐划痕性, 延长不锈钢不粘锅的使 用寿命, 且不粘层均匀、 透明, 厚度仅为 1 ~ 5 μ ηι, 突出不锈钢锅表面的金属质 感和整体美观性。 本发明所述的不锈钢不粘锅可以是炒锅、 蒸锅、 汤锅、 煎锅、 奶锅、 髙压锅、 电饭锅、 电气锅等炊具。
实施例三:
参见图 3所示, 本实施例所述的平板形不锈钢制件, 具有一不锈钢本体 1, 所述不锈钢本体 1的一表面均匀分布有圆弧形四坑, 其表面粗糙度为 Ι^1~2μηι。
本实施例所述的平板形不锈钢制件的加工, 经过的步骤与实施例一相同: 抛光—喷丸—清洗—, 其中:
(1) 抛光: 先对不锈钢本体 1要处理的表面进行镜面抛光处理, 使不锈钢本 体表面的粗糙度在 RaO.05 ~ 1 μηι之间。 通过对不锈钢本体 1表面的镜面抛光处 理, 可去除表面的氧化层和其他杂质, 保证其表面的清洁度。
(2) 喷丸: 釆用玻璃珠对不锈钢本体 1的镜面抛光面进行喷丸, 使其表面布 满均匀的圆弧形 ffl坑, 使其达到表面粗糙度为 Ι^1~2μηι。 通常上述玻璃珠粒度 为 60~160目比较适宜。 本实施例中釆用 120目玻璃珠进行喷丸处理, 经喷丸后 不锈钢本体 1的表面粗糙度为 Ral.2μηι, 使不锈钢本体表面的圆弧形凹坑的深度 均匀一致, 突出不锈钢表面的金属质感。
(3) 清洗: 将经过喷丸处理的不锈钢本体 1用加热的挥发性有机溶剂做为清 洗剂进行清洗, 以清除表面的污物, 不仅可利用热量分解一些附着在其表面上的 油质, 保证其表面的洁净, 同时还可使清洗完成后有机溶剂快速挥发, 使其表面 不会结垢, 提髙不粘层与不锈钢本体的粘接强度, 保证制品表面的美观。 本实施 例中釆用的有机溶剂为三氯乙烯, 具体清洗工艺分为三步: 第一步为粗洗, 将待 清洗的不锈钢本体浸入 50~70°C的三氯乙烯中, 同时启动 28KHz的超声波发生 器, 由有机溶剂和超声波配合进行 3分钟的清洗。 第二步为精洗, 将经过粗洗的 不锈钢本体浸入 60~70°C的三氯乙烯中, 同时启动 68KHz的超声波发生器, 持续 清洗 3分钟。 第三步为蒸汽烘干, 利用 80 ~90°C的三氯乙烯蒸汽吹扫 3分钟, 使 粘附在不锈钢本体上的三氯乙烯挥发干净。
当然也可釆用三氯乙烷等化学性能相似的挥发性溶剂做为清洗剂, 但由于不 锈钢制品为金属材质, 三氯乙烯具有较强的金属脱脂功效, 因此, 本实施例的实 施方案为优选实施方式。
在本实施例中, 为降低清洗成本及提髙清洗效率, 所述的清洗是在超声波清
洗机内进行清洗, 由于现有技术釆用髙压水枪进行清洗, 容易留下清洗死角且易 受人工因素影响, 使清洗效果不能达到技术要求, 而本工艺釆用超声波清洗机进 行清洗, 这不仅可避免人工因素对清洗效果的影响, 且还不会留下清洗死角, 保 护不锈钢制件的清洗洁净。 超声波清洗机明显提髙了产品的清洗质量, 使产品品 质更加可靠。
实施例四:
参见图 4所示, 本实施例为一种具有不粘表面的不锈钢防盗门, 所述的具有 不粘性表面的不锈钢防盗门, 包括有上述实施例一的不锈钢制件, 该制件呈防盗 门形, 具有其表面均匀分布有圆弧形四坑的不锈钢本体 1, 其表面上还附着有一 烧结不粘层 2, 所述烧结不粘层 2的厚度为 1 ~ 5 μ ηι。 所述烧结不粘层 2的材料含 有氧化硅, 烧结不粘层 2是将透明不粘材料溶液喷涂到不锈钢门表面再经烧结形 成。
本实施例所列举的具有不粘性表面的不锈钢防盗门的加工工艺是在实施例一 步骤的基础上再进行喷涂、 烧结处理。
( 4 ) 喷涂: 将透明不粘材料溶液均匀地喷涂于防盗门不锈钢本体 1的表面 上, 通过喷涂使透明不粘材料溶液均匀地覆盖不锈钢本体 1表面的圆弧形 ffl坑, 不粘材料溶液的喷涂量, 应当以烧结后形成的不粘层的厚度 1 ~ 5 μ ηι为宜。 由于 氧化硅具有三维网状结构, 在不粘材料溶液中掺入氧化硅, 这样就可使不粘材料 溶液干燥时能在不锈钢本体 1表面形成网状结构, 从而提髙不粘层 2与不锈钢本 体 1之间的粘接强度和不粘层的光洁度。
( 5 ) 烧结: 将喷涂有不粘材料溶液的不锈钢防盗门面放入烤炉内烧结 10 ~ 25 分钟, 烧结温度 200 ~ 28(TC, 通过烧结使喷涂于不锈钢本体 1表面上的不粘材料溶 液形成不粘层 2, 并完成具有不粘性表面的不锈钢防盗门的加工。 本实施例中, 烧结 时间为 20分钟, 烧结温度控制在 240 °C。
由上述工艺制成的具有不粘性表面的不锈钢防盗门, 表面强度髙, 不粘层 2与 不锈钢门的结合牢固, 增强不锈钢门表面耐蚀性和耐划痕性, 延长不锈钢防盗门 的使用寿命, 且不粘层均匀、 透明, 厚度仅为 1 ~ 5 μ ηι, 突出不锈钢防盗门表面
的金属质感和整体美观性。
实施例五:
本实施例提供一种不锈钢制品不粘表面的处理工艺, 适用于加工不锈钢装饰 材料、 不锈钢防盗门以及不锈钢厨房用品等。 该工艺包括以下步骤: 抛光→喷丸 →清洗→喷涂→烧结, 其中:
( 1 ) 抛光: 先对不锈钢制品的不锈钢本体的表面进行镜面抛光处理, 使不锈 钢本体表面的粗糙度在 RaO. 05 ~ 1 μ ηι之间。 通过对不锈钢本体表面的镜面抛光处 理, 可去除不锈钢表面的氧化层和其他杂质, 保证不锈钢表面的清洁度。
( 2 ) 喷丸: 釆用玻璃珠对不锈钢本体的镜面抛光面进行喷丸, 使不锈钢本体 表面形成均匀的圆弧形 ffl坑; 表面粗糙度 Ral ~ 2 m。 通常上述的玻璃珠粒度为
60 ~ 160 目比较适宜。 本实施例中釆用 100 ~ 120目玻璃珠进行喷丸处理, 经喷丸 后不锈钢本体的表面粗糙度为 Ral. 2 ~ 1. 3 μ ηι。 使不锈钢本体表面的圆弧形凹坑 的深度均匀一致, 突出不锈钢表面的金属质感。
通过喷丸工序可以使不锈钢本体的表面获得一定的粗糙度, 进而可以使不锈 钢本体表面得到强化, 从而可以改善不锈钢本体的机械性能, 有效提髙了不锈钢 本体的抗疲劳性。 并且, 不锈钢本体表面形成圆弧形四坑, 有利于在后续清洗工 序中彻底清洗不锈钢本体表面, 从而可保证不锈钢本体表面的清洁度, 有利于增 加不锈钢本体与涂层之间的附着力和结合力, 使不粘层与不锈钢本体粘接更牢 固, 延长了不粘层的耐久性。
由于玻璃珠表面均匀光滑, 在进行喷丸处理时, 不会对不锈钢本体表面造成 损伤产生划痕, 且使其表面上形成的四坑深度相同的圆弧形四坑, 由此易于清洗, 以保证不锈钢本体表面的清洁度, 从而提髙不粘层与不锈钢本体的粘接强度, 延 长不锈钢制品的使用寿命。
( 3 ) 清洗: 将经过喷丸处理的不锈钢本体用加热的挥发性有机溶剂做为清洗 剂进行清洗, 以清除表面的污物, 不仅可利用热量分解一些附着在其表面上的油 质, 保证不锈钢本体表面的洁净, 同时还可使清洗完成后有机溶剂快速挥发, 使 其表面不会结垢, 提髙不粘层与不锈钢本体的粘接强度, 保证其表面的美观。 本
实施例中釆用的有机溶剂为三氯乙烯, 具体清洗工艺分为三步: 第一步为粗洗, 将待清洗的不锈钢本体浸入 50 ~ 70°C的三氯乙烯中, 同时启动 28KHz的超声波发 生器, 由有机溶剂和超声波清洗配合进行 2 ~ 3分钟的清洗。 第二步为精洗, 将经 过预清洗的不锈钢本体浸入 60 ~ 70°C的三氯乙烯中, 同时启动 68KHz的超声波发 生器, 持续清洗 2 ~ 3分钟。 第三步为蒸汽干燥, 利用 80 ~ 90 °C的三氯乙烯蒸汽 吹扫 2 - 3分钟, 使粘附在不锈钢本体上的三氯乙烯挥发干净。
由于现有工艺釆用没有经过处理的硬质水对不锈钢炊具表面进行清洗, 在清 洗完成后, 不锈钢炊具表面易产生水垢, 从而影响不粘层与不锈钢炊具的粘接强 度; 而在本实施例中, 利用有机溶剂对不锈钢本体进行清洗, 而由于有机溶剂具 有较大的挥发性, 这样在清洗完成后, 残留在不锈钢本体表面的清洗液可迅速挥 发且不会产生结垢现象, 从而有效保证不锈钢本体的表面清洁度。
当然也可釆用三氯乙烷等化学性能相似的挥发性溶剂做为清洗剂, 但由于不 锈钢制品为金属材质, 三氯乙烯具有较强的金属脱脂功效, 因此, 本实施例的实 施方案为优选实施方式。
在本实施例中, 为降低清洗成本及提髙清洗效率, 所述的清洗是在超声波清 洗机内进行清洗, 由于现有技术釆用髙压水枪进行清洗, 容易留下清洗死角且易 受人工因素影响, 使清洗效果不能达到技术要求, 而本工艺釆用超声波清洗机进 行清洗, 这不仅可避免人工因素对清洗效果的影响, 且还不会留下清洗死角, 保 护不锈钢本体的清洗洁净。 超声波清洗机明显提髙了产品的清洗质量, 使产品品 质更加可靠。
( 4 ) 喷涂: 将透明不粘材料溶液均匀地喷涂于不锈钢本体的表面上, 通过喷 涂使透明不粘材料溶液均匀地覆盖在不锈钢本体表面的圆弧形四坑内, 不粘材料 溶液的喷涂量, 应当以烧结后形成的不粘层的厚度为 1 ~ 5 μ ηι为宜。 由于氧化硅 具有三维网状结构, 在不粘材料溶液中掺入氧化硅, 这样就可使不粘材料溶液干 燥时能在不锈钢本体表面形成网状结构, 从而提髙不粘层与不锈钢本体粘接强度 及不粘层的光洁度。
( 5 )烧结: 将喷涂有透明不粘材料溶液的不锈钢本体放入烤炉内烧结 10 ~ 25
分钟, 烧结温度 200 ~ 280°C, 通过烧结使喷涂于不锈钢本体表面上的透明不粘材 料溶液形成不粘层。 本实施例中, 烧结时间为 20分钟, 烧结温度控制在 230 ~ 250 。C。
