Description
技术领域
本发明涉及一种日用陶瓷生产工艺,具体是一种丝纹釉及丝纹釉日用陶瓷生产工艺,属于高分子材料技术领域。
背景技术
在陶瓷产品的烧制过程中,由于釉内含有足量的结晶性物质(熔质),经熔融后处于饱和状态,在缓冷过程中形成析晶,此类产品为结晶釉,其区别于普通釉的根本特征在于釉中含有一定数量的可见结晶体。按其晶形形态,可分为天目、雨点、茶叶末、铁锈花、菊花状、放射状、条状、水花状、星形状、松针状、螺旋状、闪星状、粒状、菱角状、羽毛状等结晶釉。
丝纹釉是结晶釉中的一种,在日本出现比较早,又叫晶纹釉。丝纹釉对坯体、原料、生产工艺、烧成的要求较高,所以成品率一般较少,不利于大规模工业化生产。
发明内容
本发明的目的在于提供一种丝纹釉及丝纹釉日用陶瓷的生产工艺,该方法可以实现丝纹釉日用陶瓷大规模工业化生产。
为实现上述目的,本发明采用的技术方案如下:一种丝纹釉釉料,其原料配方组成为:三氧化二铁6-10重量份、碳酸猛2-6重量份、氧化锆6-8重量份、石英24-36重量份、碳酸锂10-15重量份、高岭土15-25重量份。
本发明的丝纹釉釉料,由以下原料制备:三氧化二铁6-10重量份、碳酸猛2-6重量份、氧化锆6-8重量份、石英24-36重量份、碳酸锂10-15重量份、高岭土15-25重量份,其制备步骤如下:将上述原料混和后加清水进行湿法球磨,按质量比原料:球:清水=1:2:1.5,经球磨的原料通过除铁机除铁,再过300目筛,然后用清水调配成浓度为52波美度的釉料。
本发明的丝纹釉日用陶瓷生产工艺,包括如下步骤:
(1)釉料制备:取三氧化二铁6-10重量份、碳酸猛2-6重量份、氧化锆6-8重量份、石英24-36重量份、碳酸锂10-15重量份、高岭土15-25重量份,作为釉料的原料;按原料:球:清水=1:2:1.5的质量比,将上述原料混合后,加入清水进行湿法球磨,经球磨的原料通过除铁机除铁,再过300目筛,过筛原料用清水调配成浓度为52波美度的釉料,备用;
(2)坯料制备:取高岭土40-50重量份、球土5-10重量份、长石10-25重量份、石英10-20重量份、膨润土2-4重量份、紫木节土3-6重量份、废弃陶瓷3-8重量份,作为坯料的原料;将上述原料混和后加清水进行湿法球磨,经球磨的原料通过除铁机除铁,再过200目筛,通过压滤机压滤成泥块,将泥块通过练泥机进行练泥,制得质量含水率为21-23%的坯料,备用;
(3)成型修坯:取步骤(2)制得坯料,采用滚压成型机进行滚压成型;采用日用陶瓷生产的常规修坯工艺,对成型坯体表面进行修整;
(4)施釉:采用机器人自动浸釉方法,将步骤(3)修整后的坯体浸入步骤(1)制得的浓度为52波美度的釉液中浸泡2-4秒钟,使产品表面吸附釉液,形成厚度为0.4-0.5mm的釉层,得施釉坯体;
(5)烧成:将施釉坯体在隧道窑内采用氧化气氛于1220-1240℃烧成18小时,即制得产品。
优选的,步骤(3)所述高岭土44重量份、球土7重量份、长石20重量份、石英15重量份、膨润土3重量份、紫木节土5重量份、废弃陶瓷6重量份。
优选的,所述步骤(2)湿法球磨的具体工艺是将原料、清水、球按照质量比4:1:4.5放进湿法球磨机,磨制4小时。
进一步优选的,所述步骤(1)湿法球磨时间为2-4小时。
相对于现有技术,本发明的创造性在于:
(1)釉料配方进行了改良,解决了现有丝纹釉结晶效果不佳、成品率较低的问题;还可提高坯体对次釉的吸附力,提高产品釉面质量;
(2)采用机器人上釉,以机器人对经修整后的坯体进行施釉,可解决丝纹釉陶瓷产品上釉时由于受人为影响,釉面易出现不均匀、釉泡、针孔等质量问题;所采用的机器人优选六轴关节式机器人,机器人通过未端吸盘把陶瓷碗坯以倾斜姿势缓慢浸入釉池中,当整个环形碗脚被浸没后,逐渐把陶瓷碗坯摆正,并使陶瓷碗坯继续缓慢下沉,直至陶瓷碗坯的碗口边沿与釉池中的釉液面基本平齐,停止下沉,工业机器人再把施釉好的陶瓷放置到擦脚装置上进行自动擦脚,然后放回置物架干燥;
(3)技术方案整体高效、性价比高、良品率高,易于实现产业化生产。
