Abstract
本发明公开了一种煎盘的制作工艺,特点是包括取料、开料、加工成型、焊接、打磨、打砂、清洗、烘干、制备陶瓷涂料、喷涂陶瓷涂料、固化、冷却等步骤。优点是工艺简单,且能够得到质量较好的煎盘成品。
Description
技术领域
本发明涉及一种煎盘的制作工艺,尤其涉及一种烧烤炉用煎盘的制作工艺。
背景技术
目前市场上常见的烧烤炉用煎盘通常为铁煎盘,其常规的制作工艺主要分为铁板烘油、铁板打砂涂油和搪瓷三种工艺。其中,铁板烘油工艺主要是将食物油喷涂在铁煎盘表面,再进行凉干或烘干处理,这种制作工艺,煎盘的表面会粘脏污,同时会存在油的流痕以及油渍烘干后深浅不一的油黄色,导致产品的质感较差,且使用后需要涂油防潮处理,不然煎盘会生锈;铁板打砂涂油工艺主要是在铁板表面打砂后再进行防锈处理,使铁板表面具有微小的颗粒质感且保留银色的金属质感,这种制作工艺得到的产品与通过铁板烘油工艺所制作出来的产品想对比,质感明显较为优越,但是煎盘的耐磨、耐刮性差,不能受潮、淋雨,且使用一次以后仍然需要涂油防潮处理,否则会生锈;而铁板搪瓷工艺主要是通过在铁板的表面搪瓷,使制作出来的煎盘具有较好的防潮、防锈性能,同时具有较好的质感,但是搪瓷生产工艺复杂,对材料、设备、操作等要求高,容易爆搪,不能剧烈冲击,对包装运输要求高,报废率高、生产成本高,而且涂料含重金属,不卫生也不安全。
发明内容
本发明所要解决的技术问题是提供一种工艺简单、成品质量好的煎盘的制作工艺。
本发明解决上述技术问题所采用的技术方案为:
一种煎盘的制作工艺,包括如下步骤:
(1)取料:取一块冷轧板/热轧板作为基础板材;
(2)开料:根据煎盘加工所需要的规格,将基础板材裁剪成符合该规格的板料;
(3)加工成型:将板料进行冲切、折弯处理,得到初成型的煎盘;
(4)焊接:对上述初成型的煎盘的折弯处存在的边缝进行焊接处理,同时在初成型的煎盘的底部焊接上固定底座;
(5)打磨:将上步中得到的煎盘上的毛刺、焊接凸点和焊接痕迹进行打磨处理,并且对煎盘的不平整处进行整形处理,使煎盘保持平整性;
(6)打砂:将上述步骤(5)中经打磨处理得到的煎盘,用棕刚玉矿砂对煎盘的六个面进行打砂抛丸处理;
(7)清洗:对上述经过打砂处理的煎盘进行清洗处理;
(8)烘干:对上述经过清洗处理的煎盘进行烘干处理,以去除煎盘表面的水分;
(9)制备陶瓷涂料:制备用于对煎盘进行喷涂处理的陶瓷涂料,包括底漆和面漆;
(10)喷涂陶瓷涂料:将上述步骤(8)得到的煎盘预热到70℃,并利用红外线测温仪对煎盘表面的温度进行监测,当检测到煎盘表面的温度达到30—40℃内时,用上述步骤(9)中制备的底漆和面漆对煎盘进行喷涂,先喷涂一层底漆,待底漆喷完流平放置2—3分钟直接喷涂面漆;
(11)固化:待上述经喷涂处理后的煎盘表面干燥后,对其进行固化烘烤处理;
(12)冷却:上述经固化处理后的煎盘自然冷却后,得到成品。
步骤(1)中所述的基础板材的厚度为3mm—5mm。
步骤(4)中根据具体的设计需求,还需要在焊接完固定底座的煎盘上焊接上加强筋以及挡板。
步骤(6)中所用棕刚玉矿砂的粗糙度为40—60目。
步骤(6)中打砂处理时间为30分钟。
步骤(7)中具体清洗过程如下:
①用温度为40—50℃的清水对煎盘进行第一次喷淋冲洗,设定喷淋压力为0.1—0.2MPa;
②脱脂:将上述经第一次喷淋冲洗的煎盘进行用除油槽液进行脱脂处理,去除煎盘表面附着的油脂;
③用常温的清水对经过上述经过脱脂处理的煎盘进行第二次喷淋冲洗,设定喷淋压力为0.1—0.2MPa;
④用常温的清水对经过对上述经过第二次喷淋冲洗的煎盘进行第三次喷淋冲洗,设定喷淋压力为0.1—0.2MPa。
脱脂处理过程中所用的除油槽液为碱性脱脂剂SD-212A和脱脂剂SD-212B按照1:1的比例与自来水调配成而成,除油槽液的浓度为5%,除油槽液的PH值为10—12,除油槽液的碱度为10—20mls。
其中碱性脱脂剂的主要成份为碱和碱金属盐(氢氧化钠、碳酸钠、硅酸钠和磷酸钠);碱性脱脂剂SD-212A的成分为渗透剂20%、乳化剂OP30%、1310-73-2纯碱5%和余量水;脱脂剂SD-212B的成分为渗透剂20%、低泡乳化剂30%、消泡剂2%、497-19-8纯碱5%和余量水。
步骤(8)中烘干处理的温度为120—150℃。烘干处理时间以把煎盘表面的水烘干为准。
步骤(9)中底漆和面漆的具体制备如下:
①底漆的制备:取型号为2N-780A的黑色陶瓷涂料,将其放置在转速为100—150转/分钟的滚动机上滚动30分钟,至黑色陶瓷涂料中的沉淀物完全消失为止;称取上述搅拌好的黑色陶瓷涂料与型号为2N-780B的黑色陶瓷涂料按1:1的比例放入到一个密封容器中,将该密封容器放置在转速为100—150转/分钟的滚动机上滚动2—3小时,得到熟化后的底漆;将上述经熟化处理后得到的底漆用150—200目的筛网过滤,得到喷涂所需的底漆;
②面漆的制备:称取陶瓷罩光油A和陶瓷罩光油B按1:2的比例放入到一密封容器中,将该密封容器放置在转速为100—150转/分钟的滚动机上滚动2—3小时,得到熟化后的面漆;将上述经熟化后得到的面漆用150—200目的筛网过滤,得到喷涂所需的面漆。
上述涂料不含重金属等有害物质,使得制得的煎盘更加卫生、安全、环保。
步骤(10)中要求喷房的环境温度在26—30℃之间,喷涂的每一层的涂层厚度控制在20—40um。
步骤(11)中固化烘烤的温度为190—200℃,固化烘烤时间为30分钟。
与现有技术相比,本发明的优点在于:
(1)上述工艺对用于制作煎盘的基础材料即铁板板材的成分无特别要求,使用普通冷板/热轧板均可,故本工艺对取料的要求较低,使得生产成本较低;
(2)经过步骤(6)的打砂处理,使得煎盘表面具有细小的凹凸颗粒状质感,制得的产品表面光洁,具备良好的品质卖相,另外打砂形成的砂眼,增强了煎盘表面陶瓷的附着力,使煎盘具备了优良的耐刮性、耐磨性,延长了煎盘的使用寿命;
(3)经过步骤(7)的清洗处理,可除去煎盘表面的油渍、污垢、灰尘、金属颗粒等,确保煎盘的喷涂有效、均匀,煎盘外观整洁,确保良好的附着力;

具体实施方式
以下结合实施例对本发明作进一步详细描述。
一种煎盘的制作工艺,包括如下步骤:
(1)取料:取一块冷轧板/热轧板作为基础板材;
(2)开料:根据煎盘加工所需要的规格,将基础板材裁剪成符合该规格的板料;
(3)加工成型:将板料进行冲切、折弯处理,得到初成型的煎盘;
(4)焊接:对上述初成型的煎盘的折弯处存在的边缝进行焊接处理,同时在初成型的煎盘的底部焊接上固定底座;
(5)打磨:将上步中得到的煎盘上的毛刺、焊接凸点和焊接痕迹进行打磨处理,并且对煎盘的不平整处进行整形处理,使煎盘保持平整性;
(6)打砂:将上述步骤(5)中经打磨处理得到的煎盘,用棕刚玉矿砂对煎盘的六个面进行打砂抛丸处理;
(7)清洗:对上述经过打砂处理的煎盘进行清洗处理;
(8)烘干:对上述经过清洗处理的煎盘进行烘干处理,以去除煎盘表面的水分;
(9)制备陶瓷涂料:制备用于对煎盘进行喷涂处理的陶瓷涂料,包括底漆和面漆;
(10)喷涂陶瓷涂料:将上述步骤(8)得到的煎盘预热到70℃,并利用红外线测温仪对煎盘表面的温度进行监测,当检测到煎盘表面的温度达到30—40℃内时,用上述步骤(9)中制备的底漆和面漆对煎盘进行喷涂,先喷涂一层底漆,待底漆喷完流平放置2—3分钟直接喷涂面漆;
(11)固化:待上述经喷涂处理后的煎盘表面干燥后,对其进行固化烘烤处理;
(12)冷却:上述经固化处理后的煎盘自然冷却后,得到成品。
步骤(1)中所述的基础板材的厚度为3mm—5mm。选用此范围规格的的铁板综合了烤炉设计的经济性和实用性,小于3mm的基础板材在打砂和烧烤过程中容易发生变形,导致烧烤效果不够理想;而选用的基础板材的料厚大于5mm的,材料贵,不经济。
步骤(4)中根据具体的设计需求,必要情况下需要在焊接完固定底座的煎盘上焊接上加强筋以或加装挡板。当煎盘比较大的情况下,在烧烤过程中受热容易变形、翘曲,在此情况下通过在煎盘底部焊接加强筋/加装隔热板等以强化结构,减小变形量。
步骤(6)中所用棕刚玉矿砂的粗糙度为40—60目。棕刚玉具备更高的硬度,打砂效果更好,损耗相对更低,成本低,选择40—60目颗粒大小的棕刚玉打砂出来的表面粗糙度能够得到更好的煎盘外观和质感。
步骤(6)中打砂处理时间为30分钟。打砂处理时间设定在30分钟,能够确保煎盘各个面都打砂充分,粗糙度比较一致,控制在该时间是综合了实用性和经济性双重考量确定的。
步骤(7)中具体清洗过程如下:
①用温度为40—50℃的清水对煎盘进行第一次喷淋冲洗,设定喷淋压力为0.1—0.2MPa;
40—50℃的清水具备更好的溶解性,能够更好地溶解并清除煎盘上的油污;此步骤对是为了清除煎盘工件表面的大颗粒油污粉尘等,为下一步脱脂做好准备,降低对对脱脂等清洗剂的消耗;喷淋压力的选择是经济性和实用性综合考量的最优选择;
②脱脂:将上述经第一次喷淋冲洗的煎盘进行用除油槽液进行脱脂处理,去除煎盘表面附着的油脂;
此步骤是为了将附着在煎盘表面的顽固的油脂得以溶解、分解;
③用常温的清水对经过上述经过脱脂处理的煎盘进行第二次喷淋冲洗,设定喷淋压力为0.1—0.2MPa;
此步骤是为了清洗掉经过脱脂后煎盘表面的脱脂剂、脱脂分解残留和细小粉尘等;喷淋压力的选择是经济性和实用性综合考量的最优选择;
④用常温的清水对经过对上述经过第二次喷淋冲洗的煎盘进行第三次喷淋冲洗,设定喷淋压力为0.1—0.2MPa。此步骤是为了精洗上一步清洗后继续残留在煎盘表面的剩余残留的的脱脂剂、脱脂分解残留和细小粉尘等;喷淋压力的选择是经济性和实用性综合考量的最优选择。
脱脂处理过程中所用的除油槽液为碱性脱脂剂SD-212A和脱脂剂SD-212B按照1:1的比例与自来水调配成而成,除油槽液的浓度为5%,除油槽液的PH值为10—12,除油槽液的碱度为10—20mls。
其中碱性脱脂剂的主要成份为碱和碱金属盐(氢氧化钠、碳酸钠、硅酸钠和磷酸钠);碱性脱脂剂SD-212A的成分为渗透剂20%、乳化剂OP30%、1310-73-2纯碱5%和余量水;脱脂剂SD-212B的成分为渗透剂20%、低泡乳化剂30%、消泡剂2%、497-19-8纯碱5%和余量水。
步骤(8)中烘干处理的温度为120—150℃。烘干处理时间以把煎盘表面的水烘干为准。上述温度的选择是经济性和实用性综合考量的最优选择。
步骤(9)中底漆和面漆的具体制备如下:
①底漆的制备:取型号为2N-780A的黑色陶瓷涂料,将其放置在转速为100—150转/分钟的滚动机上滚动30分钟,至黑色陶瓷涂料中的沉淀物完全消失为止;称取上述搅拌好的黑色陶瓷涂料与型号为2N-780B的黑色陶瓷涂料按1:1的比例放入到一个密封容器中,将该密封容器放置在转速为100—150转/分钟的滚动机上滚动2—3小时,得到熟化后的底漆;将上述经熟化处理后得到的底漆用150—200目的筛网过滤,得到喷涂所需的底漆;
②面漆的制备:称取陶瓷罩光油A和陶瓷罩光油B按1:2的比例放入到一密封容器中,将该密封容器放置在转速为100—150转/分钟的滚动机上滚动2—3小时,得到熟化后的面漆;将上述经熟化后得到的面漆用150—200目的筛网过滤,得到喷涂所需的面漆。
上述涂料不含重金属等有害物质,使得制得的煎盘更加卫生、安全、环保。
上述涂料采用的是广州爱先新材料有限公司生产的水性陶瓷涂料。
步骤(10)中要求喷房的环境温度在26—30℃之间,喷涂的每一层的涂层厚度控制在20—40um。上述环境温度,利于涂料附着,也适工人工作,温度过低,将涂料喷涂在工件表面时,涂料的附着性差;陶瓷涂料层过薄,使得涂料不能够有效的覆盖煎盘表面,导致产品不合格;而陶瓷涂料过厚,会导致产品较脆,容易损坏,也不经济。
步骤(11)中固化烘烤的温度为190—200℃,固化烘烤时间为30分钟。温度过低或者固化时间不足,陶瓷在煎盘表面的附着力达不到要求,会产生脱落等问题;而温度过高或固化时间过长,易导致陶瓷老化,使得煎盘表面的色泽不一致,存在色差等问题;上述设计的温度和时间,能够得到质量较为优越的成品。
