Description
技术领域
本发明涉及卫生陶瓷生产技术领域,尤其涉及一种卫生陶瓷泥浆制备方法及研磨料硬度的测定方法。
背景技术
卫生陶瓷的生产工艺主要包括:泥浆的制备、注浆成型、干燥、施釉和烧制等。其中,泥浆的制备尤其重要:随不同季节及原料特性等的不同,泥浆的品质对最终烧制出来的卫生陶瓷影响巨大。
泥浆的制备工艺为:将原料混合后,加入一定量的水进球磨机研磨,然后进行陈腐操作,即研磨后在一定温度下搅拌一段时间,即得泥浆。
在注浆成型过程中,泥浆水分含量尤为重要:泥浆的含水较低,注浆成型过程不流畅,容易阻塞模具的注浆管路,且在后续干燥过程中,坯料容易崩裂;泥浆含水较高,注浆后形成的液体浆液过多,会在模具与坯料之间形成较大的间隙,最终导致无法成型。特别因季节及原料特性等不同,不同的泥浆在陈腐后,泥浆中的水分含量更不稳定,这些现象一般在注浆成型过程才体现出来(坯料崩裂或无法成型),此时将造成整批泥浆均需重新制备,造成极大的原料浪费,同时降低了生产的效率。
有鉴于此,需要提供一种能够有效控制泥浆品质的泥浆制备方法。
发明内容
本发明的目的是为了克服现有技术的不足,提供了一种卫生陶瓷泥浆制备方法,通过引入硬度测定,有效地对泥浆的品质进行了控制,解决了现有技术中因泥浆品质无法有效控制造成的原料浪费及生产效率地的问题。
本发明是通过以下技术方案实现:
一种卫生陶瓷泥浆制备方法,包括以下步骤:
S1块状原料粉碎:将块状原料破碎至粒径为1~3mm,待用;
S2原料磨浆:将粉碎后的块状原料与软质原料混合,一起入球磨机研磨16~28h,且球磨机中加入适量的水,以使得研磨后所得研磨料的硬度为25~35HA;
S3陈腐:将S2中所得物加入搅拌池,在45~50℃下搅拌5~9d。
进一步地,S2中向球磨机中加入适量的水,以使得研磨后所得研磨料的硬度为28~32HA。
进一步地,S2中向球磨机中加入适量的水,以使得研磨后所得研磨料的硬度为30HA。
进一步地,研磨料的硬度采用邵氏硬度计测定。
进一步地,S2中球磨机研磨时,每间隔4h测定一次硬度值。
上述技术方案中,块状原料包括长石、方解石、白云石、滑石、萤石,以及还包括废瓷片,软质原料包括球土、高岭土、瓷土,等。
本发明还提供了一种对上述研磨料进行硬度测定的方法,即:向石膏三角模具中注入研磨料,1~2h后将产生的液体浆料放出,再过1~2h后用邵氏硬度计测定硬度值。
与现有的技术相比,本发明有以下有益之处:
1)通过引入硬度测定,较含水量控制更有效地保证了泥浆的品质;
2)通过硬度测定,能及时发现研磨料硬度异常,及时作出调整,有效地防止了原料浪费,提高了生产效率;
3)提供的硬度测定方法能够方便对球磨机研磨料进行研磨,不会增加生产工艺的复杂程度。
