Description

一种中温高白瓷泥的制备方法
技术领域
本发明属于陶瓷制备技术领域,具体涉及一种中温高白瓷泥的制备方法。
背景技术
随着人们对美好生活的向往,艺术的眼光越来越高,刚当陶瓷酒瓶的实用性、艺术性和欣赏性越来越受市场的青睐,对陶瓷酒瓶的品质要求也越来越高,认识到某些釉上贴花瓷器有铅镉溶出之害,转向使用纯白胎瓷,市场对高白瓷需求日增。
高白瓷是应用低铁钛高纯度原料,采用合理的坯料配方,经精加工配制,以高温还原烧制而成,根据坯料不同设计透明釉、半乳白釉及乳白釉,成品多为素白瓷。
而传统的高白瓷泥配方,具有泥浆流动性差、泥浆塑形差、成瓷热稳定性、成瓷白度不理想等缺陷,导致其成品率低、价格昂贵。
为此,现有的德化白瓷生产者试图改变传统白瓷的釉料配方以获得更优质的白瓷产品。如申请公布号为CN105417953A的发明专利申请公开了一种陶瓷玉白釉料及其施釉,该种陶瓷玉白釉料,原料包括钠长石、碳酸钙、高岭土、石英、碳酸钡、硼酸钙、碳酸锶、皂土、甲基纤维素。该种陶瓷玉白釉料及其施釉所追求的是一种油润肥厚的釉面效果,在高温烧成时釉料会垂流,随着釉汁流淌积淀。此外,该种玉白釉料制作时陶瓷坯体必须经过素烧后,通过多道工序,再进行浸釉、喷釉、两道工序,才可生产出陶瓷制品,生产工序复杂并且成品率低。
公司根据市场需求,录用外购成品泥(外购技术)的方式来实用市场生产,取得了些许的效果,但受到方方面面的桎梏,受制于人。因此,制备一种来源方便,成本低,白度高,流动性好、热稳定性和收缩稳定性好的白瓷泥具有非常重大意义。
发明内容
本发明所要解决的技术问题:针对现有的陶瓷泥化浆性能不适应现有生产,成瓷收缩不稳定,成品率低等问题,提供了一种中温高白瓷泥的制备方法。
为解决上述技术问题,本发明采用的技术方案是:
(1)中温高白瓷泥原料组成:按重量份数计,分别选取20~30份钾钠砂、15~20份广西白沙、20~30份福建淘洗泥、3~5份滑石、1~3份石英粉和1~3份贵州土;
(2)将步骤(1)中钾钠砂、广西白沙、福建淘洗泥、滑石和石英粉依次加入破碎机中破碎,破碎至总物料60~65%的目数达到200以上,收集得混合粉末,将混合粉末进入磁选机磁选,去除铁磁性物杂质;
(3)将步骤(2)除杂后的混合粉末加入分散剂,并和贵州土混合,混合后装入球磨机中进行湿法球磨,球磨5~10h后出料,得浆料;所述的料∶球∶水=1∶2∶1.2;
(4)将浆料加入浮选池中,并加入浮选药剂除杂,将浮选后浆料加入高梯度强磁选机中进一步除铁,得精制浆料;
(5)将精制浆料脱水至浆料的含水量为30~40%,随后加入真空练泥机中练泥,得泥料后陈腐,重复真空练泥和陈腐2~3次,真空脱泡,即可得到中温高白瓷泥。
步骤(3)所述的分散剂为三聚磷酸钠、六偏磷酸钠或聚丙烯酸铵中的一种,加入量为混合粉末质量的1~2%。
还可以向步骤(3)的混合粉末中加入碳酸钠,加入量为混合粉末质量的0.1~0.2%。
步骤(4)所述的浮选药剂是按重量份数计,分别选取30~50份松醇油、5~10份烷基糖苷、10~20份丁黄药、1~3份硫酸铜,混合后即可得到浮选药剂。
步骤(5)所述的陈腐环境为密封环境,每次陈腐时间为10~20h。本发明与其他方法相比,有益技术效果是:
(1)本发明制备中温高白瓷泥工艺简单,配方合理,其烧制温度在1200℃以下,比传统陶瓷烧制温度要低,因此其能耗低,降低成本;
(2)本发明选用了钾钠砂、广西白沙,福建优质淘洗泥等材料进行优化组合,在较低成本的前提下生产出了优质的中温高白瓷坭,并加入分散剂,使制得的瓷泥具有良好化浆性能,浆料流动性好,加入分散剂后还可以加入碳酸钠,其目的是为了补充浆料中的电解质,使浆料更好的进行化浆,提高浆料的稳定性和渗透性;
(3)本发明通过广西白沙等原材料的引入,对高白瓷坭在化浆状态下的颗粒匹配,渗透性能,操作性能有了质的改善,制备的成瓷白度得到提高,热稳定性得到改善,收缩的稳定性控制,提高成品率,大大降低生产成本,具有非常重大意义。

(1)中温高白瓷泥原料组成:按重量份数计,分别选取20~30份钾钠砂、15~20份广西白沙、20~30份福建淘洗泥、3~5份滑石、1~3份石英粉和1~3份贵州土;
(2)将步骤(1)中钾钠砂、广西白沙、福建淘洗泥、滑石和石英粉依次加入破碎机中破碎,破碎至总物料60~65%的目数达到200以上,收集得混合粉末,将混合粉末进入磁选机磁选,去除铁磁性物杂质;
(3)将步骤(2)除杂后的混合粉末加入分散剂,并和贵州土混合,混合后装入球磨机中进行湿法球磨,球磨5~10h后出料,得浆料;所述的料∶球∶水按质量比为1∶2∶1.2;
(4)将浆料加入浮选池中,并加入浮选药剂除杂,将浮选后浆料加入高梯度强磁选机中进一步除铁,得精制浆料;
(5)将精制浆料脱水至浆料含水量为30~40%,随后加入真空练泥机中练泥,得泥料后陈腐,重复真空练泥和陈腐2~3次,真空脱泡,即可得到中温高白瓷泥;
将步骤(2)除杂后的混合粉末中加入分散剂和碳酸钠,碳酸钠加入量为混合粉末质量的0.1~0.2%;步骤(4)所述的浮选药剂是按重量份数计,分别选取30~50份松醇油、5~10份烷基糖苷、10~20份丁黄药、1~3份硫酸铜,混合后即可得到浮选药剂。
2.根据权利要求1所述的一种中温高白瓷泥的制备方法,其特征在于:步骤(3)所述的分散剂为三聚磷酸钠、六偏磷酸钠或聚丙烯酸铵中的一种,加入量为混合粉末质量的1~2%。
3.根据权利要求1所述的一种中温高白瓷泥的制备方法,其特征在于:步骤(5)所述的陈腐环境为密封环境,每次陈腐时间为10~20h。
