氧化镁水泥工艺品的应用 Application of magnesia cement crafts

    http://www.ykbhlm.com氯氧镁胶凝材料（俗称镁水泥），具有不燃、无毒、无放射性、不含重金属、不含石棉、不含有机挥发物的特点。产品生产过程低碳、节能，产品和使用完的废弃物均绿色环保，不污染环境，原料本身调和性能好，着色容易。这些优点使镁水泥成为很多厂家选用的原料。

一、镁水泥在工艺品方面的应用。

   1.建筑装饰、装修方面。随着物质、文化生活水平的提高，在城市化进程中，人们对室内外装饰装修风格多样化的要求也越来越高，艺术建材应时而生。用镁水泥可设计、生产出中、欧等不同风格的浮雕壁材、浮雕壁画和装饰构件，以满足装饰装修风格多样化的需要。

   2.园林景点、旅游环境、公共场所、生活社区等场所的各种装饰品、摆设品，如景观造型、雕塑、花盆、花台、罗马柱、灯座、假山石、脚踏板、茶几座、仿石仿木桌凳、烧烤炉、动物、人物等具有艺术造型的产品。

   3.馈赠礼品、室内摆放工艺品，如各种景观、造型、人物、动物等。

   4.市政工程需要的产品，如艺术地砖、艺术路沿石、路灯座、艺术井盖等。

二、生产镁水泥工艺品的条件。

生产、制造镁水泥工艺性质的产品，必须具备两个最基本的条件：1.稳定合格的轻烧镁粉原料。2.科学的配比原料、合理的工艺和合适的养护方式。

这两点是生产、制造镁水泥工艺品（也包括所有镁水泥制品）最基本、最重要的条件。这方面的历史教训是深刻的，必须引起足够的重视。

  从第一点来讲，合格的氧化镁是做好镁水泥的基础。适合做镁水泥的轻烧氧化镁是在750℃-900℃煅烧分解的，这种温度烧出的氯化镁才能和氧化镁、水在短期内形成反应相结构，我们把它称为具有活性的氧化镁，这样的轻烧粉适合做所有的镁水泥制品。在行业标准中，已对轻烧镁粉的活性氧化镁含量、烧失量、过烧氧化钙含量进行了明确的规定，有的厂家把轻烧氧化镁分为防火板专用氧化镁、通风管道专用氧化镁、墙板专用氧化镁、工艺品专用氧化镁。不知道这种分类的标准和依据是什么，因为镁水泥制品有几十种、几百种，难道轻烧氧化镁也要分几十种、几百种吗？再加上市场上不合格的氧化镁继续进行价格的无序竞争，这些都给下游工厂带来产品不稳定的因素。多年来，地方政府也对氧化镁生产厂家进行了多次整顿，主要出发点是从减少资源浪费、合理利用资源、环保、节能的角度出发，如何使轻烧镁粉达标生产以满足下游工厂需要，建立稳定原料供应基地，促进镁水泥行业健康发展，始终缺乏监管和制度，这也是很多镁水泥制品企业不敢和不能做大、做强的原因之一。

   从第二点来讲，科学配料、合理工艺、合适养护是做好镁水泥产品的必要条件。关于科学配料，余红发教授在总结国家“七五”攻关的科研成果时提出的“配料原则”，是所有镁水泥制品配料时必须遵循的原则，根据镁水泥制品的不同品种和使用范围，只能在这个原则范围内灵活调整，而不能背离这个原则。

   为了便于记忆和理解这两点中的内容，可以用一句通俗、便于记忆的词语，就是生产镁水泥制品必须“坚持四项基本原则”，即坚持使用达标原料的原则、坚持科学配料的原则、坚持合理工艺的原则、坚持合适养护的原则。这四项基本原则是根据镁水泥内在的化学反应和物理特征提出的，缺一不可，相辅相成，才能较好地完成镁水泥内部的化学物理反应过程，使产品达到较长时间的使用价值。

   镁水泥工艺品的生产只有在达到内在的质量要求之后，再加上形式和外观的装饰手法，才能开发和生产出更多的品种，满足社会的物质、文化需求。

The production process of the product is low-carbon, energy-saving, the product and the used waste are environmentally friendly, do not pollute the environment, the raw material itself has good blending performance, and it is easy to color. These advantages make magnesium cement the raw material of choice for many manufacturers.

First, the application of magnesium cement in crafts.

   1. Building decoration and decoration. With the improvement of material and cultural living standards, in the process of urbanization, people's requirements for the diversification of interior and exterior decoration styles have become higher and higher, and art and building materials have emerged from time to time. With magnesium cement, it is possible to design and produce embossed wall materials, embossed murals and decorative components in different styles in China and Europe to meet the diverse needs of decorative styles.

   2. Garden decorations, tourist environments, public places, living communities and other places, such as landscape decorations, sculptures, flower pots, flower stands, Roman columns, lamp holders, rockery, foot pedals, coffee table seats , Imitation stone imitation wooden bench, barbecue stove, animals, characters and other products with artistic shapes.

   3. Gifts and indoor crafts, such as various landscapes, shapes, figures, animals, etc.

   4. Products required for municipal engineering, such as artistic floor tiles, artistic roadside stones, street lamp holders, and artistic manhole covers.

Second, the conditions for the production of magnesium cement crafts.

Production and manufacturing of products with magnesium cement technology must have two basic conditions: 1. Stable and qualified raw materials for light burning magnesium powder. 2. Scientific ratio of raw materials, reasonable craftsmanship and appropriate maintenance methods.

These two points are the most basic and important conditions for the production and manufacture of magnesium cement handicrafts (including all magnesium cement products). The historical lessons in this regard are profound and must be given sufficient attention.

  From the first point, qualified magnesium oxide is the basis for good magnesium cement. Light-burned magnesium oxide suitable for magnesium cement is calcined and decomposed at 750 ° C-900 ° C. The magnesium chloride burned at this temperature can form a reactive phase structure with magnesium oxide and water in a short period of time. Magnesium, such a light burnt powder is suitable for all magnesium cement products. In the industry standard, the active magnesium oxide content, loss on ignition, and over-calcium oxide content of light-burned magnesium powder have been clearly defined. Some manufacturers have classified light-burned magnesium oxide into special magnesium oxide for fire prevention boards and ventilation ducts Special magnesium oxide, special magnesium oxide for wallboard, special magnesium oxide for crafts. I don't know what the classification criteria and basis are, because there are dozens or hundreds of magnesium cement products. Is it necessary to divide dozens or hundreds of lightly burned magnesium oxide? In addition, the unqualified magnesium oxide in the market continues to compete in disorderly prices, which has brought factors that cause product instability to downstream plants. Over the years, local governments have also rectified the magnesium oxide manufacturers several times. The main starting point is how to make light-burned magnesium powder meet the requirements of downstream plants from the perspective of reducing waste of resources, rational use of resources, environmental protection and energy saving. Establishing a stable raw material supply base to promote the healthy development of the magnesium cement industry. There is always a lack of supervision and systems. This is one of the reasons why many magnesium cement products companies are afraid to and cannot grow larger and stronger.

   From the second point, scientific ingredients, reasonable technology, and proper maintenance are necessary conditions for good magnesium cement products. Regarding scientific ingredients, Professor Yu Hongfa's "Batching Principles", which he put forward when summarizing the scientific research achievements of the "Seventh Five-Year Plan" period of the country, is a principle that must be followed when all magnesium cement products are blended. Adjust flexibly within the scope of this principle without departing from it.

   In order to facilitate the memorization and understanding of the contents of these two points, a simple and memorable word can be used, that is, the production of magnesium cement products must "adhere to the four basic principles", that is, the principle of using up-to-standard raw materials, the principle of scientific ingredients, Adhere to the principle of reasonable craftsmanship and the principle of proper maintenance. These four basic principles are proposed based on the inherent chemical reaction and physical characteristics of magnesium cement. All of them are indispensable and complement each other in order to complete the chemical and physical reaction process inside the magnesium cement and make the product reach a long-term use value.

   Only after the production of magnesium cement handicrafts meets the internal quality requirements, plus the decoration methods of form and appearance, can it develop and produce more varieties to meet the material and cultural needs of society.
