Barium sulfate is generally non-toxic to humans, and barium sulfate belongs to insoluble deposits that are not digested in the body and excreted. In the hospital to do gastric examination, it is the use of barium sulfate non-toxic to the human body. In addition to barium sulfate, some other soluble barium salts or barium salts that react with gastric acids are harmful to humans, because heavy metal ions can destroy human proteins and impede the normal biochemical response of the human body. Barium sulfate insoluble in water, insoluble in sulfuric acid, hydrochloric acid, nitric acid and other strong acids. Barium sulfate is used as a barium meal in human gastric juice, which contains low levels of hydrochloric acid. Taking barium meal as a contrast agent of gastroscope is basically harmless to the body. Barium carbonate must not be used because barium chloride is soluble in hydrochloric acid to produce highly toxic barium chloride, which causes death.

　　硫酸钡防护措施：

　　Barium sulfate, protective measures:

　　1、硫酸钡无害，不小心溅到身上，用水搓洗即可。

　　1, barium sulfate and harmless, careful not to splash water to scrub.

　　2、长久工作在这样的环境，容易患职业病：尘肺。硫酸钡生产时，工人应该做好防护措施，配带劳保。

　　2, long-term work in such an environment, prone to occupational diseases: pneumoconiosis. Barium sulfate production, workers should do a good job of protective measures, with labor insurance.

　　3、在生产硫酸钡的时候，应该厂房密闭，防止粉尘污染坏境。

　　3, in the production of barium sulfate, the plant should be closed, to prevent dust pollution.

　　4、应该有伤害,但很小.硫酸钡是难溶物,有毒的钡无法电离,进而较难进入人体,但总有极微量的钡离子,会对人体造成伤害.医院给病人胃造影用的就是硫酸钡的悬浊液,伤害很小。

　　4, there should be hurt, but very small. Barium sulfate is insoluble, toxic and difficult to be ionized barium, into the body, but there is always a trace amount of barium ions, can cause harm to human body. The hospital for patients with gastric angiography is used in barium sulfate suspension injury is very small.

硫酸钡如何使油漆颜色更白光泽度更亮?
　　硫酸钡在油漆行业的使用情况很普遍，在油漆生产工艺过程当然也是必不可缺少的填充原料之一，如何控制硫酸钡在油漆中的添加量呢，这就是个经验问题，如果添加的少的话，容易造成亮度比较低，添加太多的话，就会造成油漆在喷涂后过于鲜亮，所以起到的效果不适中，另外还跟硫酸钡的质量好坏也有一定要求，如果硫酸钡的白度好，钡含量高的话，就能提高油漆产品的质量，相反，如果硫酸钡的白度，钡含量低，对于油漆质量会产生很大的影响的，所以从事油漆生产企业一定要注意这个因素。

　　The use of barium sulfate in the paint industry is very common, in the production process of paint is of course will fill one of the raw materials can not be missing, how to control the barium sulfate in paints in addition, this is a question of experience, if you add a little, easy to cause the brightness is low, add too many words that will result in paint spraying too bright, so the effect is moderate, in addition to the quality of barium sulfate have certain requirements, if the whiteness of barium sulfate, barium content high, can improve the quality of products, paint the contrary, if the whiteness of barium sulfate, barium content the paint quality is low, will have a great impact, so in paint production enterprises must pay attention to this factor.

　　硫酸钡在不断开拓其品质优势能力体现的前提下，要以优势能力的开拓来增强其整体发展的实用效果，透过产品整体性带动，来迅速体现出产品实用基础能力的发展，充分提升产品实用基础的不断完善。产品质量提高了，产品成本降低了。选择硫酸钡就成了众多油漆厂家的首先填充料。

　　The premise of barium sulfate in the pioneering quality advantage of the ability to reflect, to develop the advantage of ability to enhance the overall development of practical effect, through the whole product driven, to quickly reflect the development of basic products and practical ability, and fully enhance products and constantly improve the practical basis. The quality of the product has been raised, and the cost of the product has been reduced. Barium sulfate has been chosen as the first filling material for many paint manufacturers.

　　当然，有些硫酸钡厂家为了获利，硫酸钡的质量并不纯，可能会添加其他白色粉末，所以在购买硫酸钡的时候，一定要仔细检查好硫酸钡厂家的产品质量及产品的纯度，确保质量没有任何问题的时候在放心购买，如果硫酸钡的质量存在问题的话，容易造成生产的油漆产品出现问题，所以一定要注意这方面的因素。

　　Of course, some manufacturers of barium sulfate in order to make a profit, the quality of barium sulfate is not pure, may add other white powder, so when the purchase of barium sulfate, the purity of product quality must be carefully check the barium sulfate manufacturers and products, ensure quality without any problems in the buy, if there is a problem of quality barium sulfate, easy to cause the paint production problems, so we must pay attention to these factors.
