Description

一种陶瓷及其制备方法
技术领域
本发明属于陶瓷制备技术领域,尤其涉及一种陶瓷及其制备方法。
背景技术
陶瓷产业是高耗能、高污染、高耗资源及低产出的行业,为了解决“三高一 低”的问题,陶瓷行业的工程技术人员采取了建筑陶瓷薄型化、卫生陶瓷轻型化 的措施。
一般地企业会采取高品位的原料用作陶瓷坯体的配方,由于原料中AI2O3 的含量较高,造成了陶瓷坯体的烧成温度也较高,大多数陶瓷厂的陶瓷坯体配 方烧成温度为1300℃左右。通常企业会采取把窑炉加宽、加长(一般可达500 米)的措施达到节能降耗的目的,以便实现快速烧成。但是上述方法需要企业 投入大量的资金用于改造窑炉,而且窑炉的占地空间也会受到一定的限制,如专利号CN02148394.9提出的一种陶瓷与生产工艺。
此外,据中国建筑卫生陶瓷协会提供的信息,我国有陶瓷企业近万家,每 年优质高岭土用量达2.8亿吨,以如此速度运行下去,我国50年后,优质高岭土就会枯竭,大多数陶瓷企业将面临艰难抉择。因此,探究陶瓷坯体新配方的任务已迫在眉睫。

优选的,所述熔剂为页岩;
优选的,所述助熔剂为石灰石、方解石、透辉石、硅灰石、白云石、滑石、工业 废渣中的一种或几种;
优选的,所述粘土采用高岭土;
优选的,所述釉浆采用喷的方式涂覆与干坯表面;
一种陶瓷的制备方法,包括以下步骤:
a.按上述陶瓷重量分别称取瓷石、粘土、熔剂和助熔剂;
b.将所述瓷石打碎磨粉,并过250目筛进行筛选;
c.将打碎后的瓷石粉、粘土、助熔剂和熔剂加水球磨制得料浆,并将所得料浆过250目筛筛余量为2-2.2%,含水率33-37%,粘度为155-205mpa.s;
d.将所得料浆加压干燥制得粉料,所述粉料的含水率为4-8%;
e.将所述粉料压制成型,并放置于80-90度下干燥60-70分钟,获得干坯,所述干坯的含水率为1-3%;
f.将所述干坯表面涂覆釉浆,得到釉坯;
g.将所述釉坯放置于1000-1300度的炉窑中烧制100-140分钟,得到陶瓷产品。
h.在上述步骤中所述釉浆为将所述釉原料投入小型球磨机中加水球磨,30~50小时后制得釉浆,所述釉浆工艺参数为:过250目筛筛余量0.2~0.4%,釉浆的含水率为33~39%,pH值 为6.5~8.5。
本发明具有的优点和积极效果如下:
1. 本发明提出的一种陶瓷及其制备方法,陶瓷组分选择合适,配比合理,紫砂页岩和页岩中含有可降低烧成温度和促进烧结的成份,此外二者的品位低,Al2O3含量低,也可降低烧成温 度。上述陶瓷制得的陶瓷产品的烧成温度为1100℃左右,比传统陶瓷坯体的烧成温度降低140℃左右,节约了能耗,减少了废气排放,而且得到的陶瓷坯 体符合国家标准。
2.由于上述陶瓷制得的陶瓷产品的烧成温度降低,所以无需对窑炉进行 加宽、加长改造以达到节能降耗的目的,因此企业技术改造投入少,使得大中 小企业都能接受,同时减少了窑炉的占地空间,上述陶瓷可以应用于日用陶瓷、工艺美术陶瓷、建筑陶瓷、卫生陶瓷、 园林陶瓷等领域,使用范围广,操作简单,便于推广。
上述陶瓷产品的制备方法,原料便宜,工艺简单,降低了烧成温度,降低 了能耗。降低了生产成本,减少了生产设备的投入,提高了生产效率和企业效益。
