紫陶缸装水有什么好处?

今天回答很多陶友都关心的与紫陶水缸有关的两个问题。

Today, I will answer two questions related to the purple pottery water tank that many Taoyou are concerned about.

一、紫陶水缸真的有透气性吗?

1、 Is the purple pottery water tank really breathable?

客观、肯定且负责任地回答您:真的。

Answer you objectively, positively and responsibly: really.

在陶瓷的分类中,有一个很大的种类叫做“炻器”。炻器在中国古代被称为“石胎瓷”,由名及义,其特点是坯体致密,已完全烧结,但是尚未玻化,是介于纯陶器与纯瓷器之间的一种制品的统称。

In the classification of ceramics, there is a large category called “stoneware”. Stoneware was called “stone body porcelain” in ancient China. From its name and meaning, it is characterized by compact body, complete sintering, but not vitrified. It is a kind of product between pure pottery and pure porcelain.

炻器还有一个很重要的特点:吸水率在6%以下。这个数据意味着什么呢?意味着烧成的陶坯在不施釉的条件下,也能够不透水。

Stoneware also has a very important feature: water absorption is below 6%. What does this data mean? It means that the fired ceramic body can also be impermeable without glaze.

吸水率与透气性有什么关系?紫陶属于一种保温材料,保温材料的吸水率和透气性就如同一对孪生兄弟。吸水率小于0.5%,坯体不透气也不透水,就是我们所说的瓷器;吸水率在0.5%~6%之间,坯体透气但不透水,就是前面所说的炻器;吸水率大于6%,透气也透水,就是尚未完全烧结的各类陶器。

What is the relationship between water absorption and air permeability? Purple pottery belongs to a kind of heat preservation material. Its water absorption and air permeability are like twin brothers. If the water absorption rate is less than 0.5%, the green body is airtight and impermeable, which is what we call porcelain; when the water absorption rate is between 0.5% and 6%, the green body is breathable but impermeable, which is the stoneware mentioned above; if the water absorption rate is greater than 6%, the air permeability is also water permeability, that is, all kinds of pottery that have not been fully sintered.

前面我们介绍炻器的特点是坯体致密,已经完全烧结,这也正是建水紫陶的特点。实际上,建水紫陶和宜兴紫砂一样,都是属于炻器的范围,具有透气性,但不透水。

Before we introduce the stoneware is the compact body, has been fully sintered, which is the characteristics of Jianshui purple pottery. In fact, Jianshui purple pottery, like Yixing purple sand, belongs to the scope of stoneware, with air permeability, but impermeable.

二、为什么说紫陶水缸具有较好的保持水质的功能?

2、 Why is it said that the purple pottery water tank has a better function of maintaining water quality?

水体具有自我净化的能力,原因之一得益于水体内部自己发生的各种氧化反应。

One of the reasons why water has the ability of self purification is due to various oxidation reactions within the water.

一缸水静置后,水体逐渐趋于平静,比水重的粒子沉降存积在缸底,易氧化的物质通过水中的氧气进行氧化;有机物通过水中微生物进行生物氧化分解,矿化后,水就恢复到原来的清洁状态,这就是水体的自净作用。

After a tank of water is standing still, the water body gradually tends to be calm, and the particles heavier than water settle and accumulate at the bottom of the tank, and the easily oxidized substances are oxidized by oxygen in the water; organic matters are biologically oxidized and decomposed by microorganisms in the water, and after mineralization, the water will return to its original clean state, which is the self purification function of water body.

这种自我净化的能力,需要水体不断地从外界获得氧气,使氧化过程中所消耗的氧气得到补充。

The ability of self purification requires water to continuously obtain oxygen from the outside, so that the oxygen consumed in the oxidation process can be replenished.

为了防止灰尘,饮用水需要尽量密封地储存,这是常识。这种环境下,需要补充空气中的氧气,只有靠透气的坯体与外界空气产生交换。

In order to prevent dust, drinking water needs to be stored as tightly as possible, which is common sense. In this environment, oxygen in the air needs to be replenished, and only the green body with air permeability can exchange with the outside air.

于是回到第一个问题,紫陶水缸恰恰是有一定的透气性的,可以通过与外界的空气交换来补充缸内水体氧化所消耗的氧气。尽管可能比较缓慢,但比瓷器水缸和胶质水桶要好得多。

So back to the first question, the purple pottery water tank is precisely a certain degree of air permeability, and the oxygen consumed by water oxidation in the tank can be replenished by air exchange with the outside world. Although it may be slow, it’s much better than a porcelain tank or a gum bucket.

所以,地下水、瓷器水缸、胶质水桶中的水,比较平静,无空气补充,其自我净化能力要比与空气接触的水差很多。地下水一旦被污染,几乎不可能恢复原来的水质;胶质水桶内的水,过一段时间,就会产生一层粘稠物质,意味着水质正在变坏,时间一长,就无法饮用了。

Therefore, the water in ground water, porcelain water tank and colloidal water bucket is relatively calm without air supplement, and its self purification ability is much worse than that of water in contact with air. Once the groundwater is polluted, it is almost impossible to restore the original water quality; after a period of time, the water in the colloidal bucket will produce a layer of viscous substances, which means that the water quality is deteriorating and can not be drunk for a long time.

另外,紫陶水缸装水的优势还有原料所含有的很多人体所需的矿物质、缸内温度较低的环境抑制有害细菌的生长速度,等等;我在以前的一篇文章里给大家介绍过了,这里就不再赘述。

In addition, the advantages of the purple pottery water tank are that the raw materials contain a lot of minerals needed by the human body, the lower temperature in the tank can inhibit the growth rate of harmful bacteria, and so on. I introduced it to you in an earlier article, and I will not repeat it here.
