Abstract
本发明涉及一种圆珠干粒及其制备方法,属于圆珠干粒制备技术领域。本发明以羧甲基纤维素钠为悬浮液主体,加入三聚磷酸钠、氯化铝和氯化铵协同作用,使悬浮液具有优异的悬浮性和分散性,将其运用到圆珠干粒的制备中,极大地增强了制备过程中体系原料颗粒的悬浮程度和分散、流动程度,有助于使制得干粒的形态极为圆润,同时,在添加悬浮液的前提下,带尖锐角的不规则干粒拥有了极好的流动性,因此,在熔炉修边处理过程中,中间干粒不易成团或卡住,修边处理能更好地进行,得到的圆珠干粒形态也极为圆润。此外,本发明还加入了碳酸锶和碳酸钡,强化了圆珠干粒成品的光泽度。
Description
技术领域
本发明属于圆珠干粒制备技术领域,具体地,涉及一种圆珠干粒及其制备方法。
背景技术
在建筑陶瓷、岩板等产品竞争日益激烈和人们对生活品质和空间美学的不断追求的前提下,陶瓷、岩板等作为家装的主体,发展到今天也已十分丰富。但同时,消费者对它们的性能要求也会越来越高,特别是针对陶瓷、岩板等产品的表面形貌、光泽度以及表面功能化的方面。为了满足以上功能,干粒类产品应运而生。目前,市面上干粒类产品其实已经琳琅满目,但市面上传统的干粒所反映的问题是,干粒圆润度和光泽度差,将其运用到产品中无法将产品的纹理、细节完美地体现出来,干粒产品显然已经无法满足市场对于干粒的高标准和高要求,由此看来,行业产品升级势在必行。基于此,提供一种圆润性和光泽度好的干粒显得尤为必要。
发明内容
本发明的目的在于提供一种圆珠干粒及其制备方法,本发明涉及一种圆珠干粒及其制备方法,属于圆珠干粒制备技术领域。本发明以羧甲基纤维素钠为悬浮液主体,加入三聚磷酸钠、氯化铝和氯化铵协同作用,使悬浮液具有优异的悬浮性和分散性,将其运用到圆珠干粒的制备中,极大地增强了制备过程中体系原料颗粒的悬浮程度和分散、流动程度,有助于使制得干粒的形态极为圆润,同时,在添加悬浮液的前提下,带尖锐角的不规则干粒拥有了极好的流动性,因此,在熔炉修边处理过程中,中间干粒不易成团或卡住,修边处理能更好地进行,得到的圆珠干粒形态也极为圆润。此外,本发明还加入了碳酸锶和碳酸钡,以碳酸锶使得体系具有较宽的烧成范围并有助于调节原料的结构和成分,减少了微观结构缺陷的存在,进而增加了光泽度,以碳酸钡提高制成圆珠干粒的折射率,进一步强化了圆珠干粒的光泽度。解决了现有技术中存在的圆珠干粒形态圆润度弱和光泽度低的问题。
本发明的目的可以通过以下技术方案实现:

S30、将烧结液体水淬,得到带尖锐角的不规则干粒;
S40、将带尖锐角的不规则干粒和悬浮液混合均匀,然后吹入熔炉中,进行控温修边处理,得到中间干粒,收集中间干粒并过筛,得到圆珠干粒成品。
作为本发明的一种优选方案,步骤S10所述过筛为过300-400目筛。
作为本发明的一种优选方案,步骤S20所述混合搅拌的时间为30-50min;所述高温烧结的步骤具体为:

作为本发明的一种优选方案,步骤S40所述控温修边处理的温度为800-850℃,所述过筛为过100-200目筛。
本发明的有益效果:
(1)本发明以羧甲基纤维素钠为悬浮液主体,加入三聚磷酸钠、氯化铝和氯化铵协同作用,使悬浮液具有优异的悬浮性和分散性,将其运用到圆珠干粒的制备中,极大地增强了制备过程中体系原料颗粒的悬浮程度和分散、流动程度,有助于使制得干粒的形态极为圆润。这是因为,三聚磷酸钠在高温过程中会被加热分解,产生磷酸盐结晶,使体系中带尖锐角的不规则干粒易于形成密实的结晶从而提高致密度,便于后续的整体流动;在此基础上加以氯化铝,氯化铝在水溶液中解离成阴离子和阳离子,这些离子可以与体系中带尖锐角的不规则干粒表面相互作用,引发表面活性效应,中和颗粒表面的电荷,在颗粒表面形成电荷屏蔽层,使得颗粒之间的相互作用减弱,从而减少了颗粒的缩聚和沉淀,使其更易于分散在溶液中;继而再以氯化铵维持悬浮液的pH值,同时增强干粒间的相互作用力,促进干粒更稳定,巩固了悬浮液的悬浮性和分散性,进一步提高了干粒的悬浮、分散、流动性。即,在添加悬浮液的前提下,带尖锐角的不规则干粒拥有了极好的流动性,因此,在熔炉修边处理过程中,中间干粒不易成团或卡住,修边处理能更好地进行,得到的圆珠干粒形态也极为圆润。
(2)本发明在原料的选取上简化了配方,并增加了市售普通圆珠干粒原料所不具备的碳酸锶和碳酸钡,强化了圆珠干粒成品的光泽度。这是因为,体系原料中加入了碳酸锶,使得体系具有较宽的烧成范围并有助于调节原料的结构和成分,减少了微观结构缺陷的存在,进而增加了光泽度,此外,还加入了碳酸钡并控制了其加入量,以碳酸钡提高制成圆珠干粒的折射率,进一步强化了圆珠干粒的光泽度。
