氧化鎂水泥工藝品的應用 Application of magnesia cement crafts

    http://www.xaqinyun.com氯氧鎂膠凝材料(俗稱鎂水泥),具有不燃、無毒、無放射性、不含重金屬、不含石棉、不含有機揮發物的特點。產品生產過程低碳、節能,產品和使用完的廢棄物均綠色環保,不污染環境,原料本身調和性能好,著色容易。這些優點使鎂水泥成為很多廠家選用的原料。

一、鎂水泥在工藝品方面的應用。

   1.建筑裝飾、裝修方面。隨著物質、文化生活水平的提高,在城市化進程中,人們對室內外裝飾裝修風格多樣化的要求也越來越高,藝術建材應時而生。用鎂水泥可設計、生產出中、歐等不同風格的浮雕壁材、浮雕壁畫和裝飾構件,以滿足裝飾裝修風格多樣化的需要。

   2.園林景點、旅游環境、公共場所、生活社區等場所的各種裝飾品、擺設品,如景觀造型、雕塑、花盆、花臺、羅馬柱、燈座、假山石、腳踏板、茶幾座、仿石仿木桌凳、燒烤爐、動物、人物等具有藝術造型的產品。

   3.饋贈禮品、室內擺放工藝品,如各種景觀、造型、人物、動物等。

   4.市政工程需要的產品,如藝術地磚、藝術路沿石、路燈座、藝術井蓋等。

、生產鎂水泥工藝品的條件。

生產、制造鎂水泥工藝性質的產品,必須具備兩個最基本的條件:1.穩定合格的輕燒鎂粉原料。2.科學的配比原料、合理的工藝和合適的養護方式。

這兩點是生產、制造鎂水泥工藝品(也包括所有鎂水泥制品)最基本、最重要的條件。這方面的歷史教訓是深刻的,必須引起足夠的重視。

  從第一點來講,合格的氧化鎂是做好鎂水泥的基礎。適合做鎂水泥的輕燒氧化鎂是在750℃-900℃煅燒分解的,這種溫度燒出的氯化鎂才能和氧化鎂、水在短期內形成反應相結構,我們把它稱為具有活性的氧化鎂,這樣的輕燒粉適合做所有的鎂水泥制品。在行業標準中,已對輕燒鎂粉的活性氧化鎂含量、燒失量、過燒氧化鈣含量進行了明確的規定,有的廠家把輕燒氧化鎂分為防火板專用氧化鎂、通風管道專用氧化鎂、墻板專用氧化鎂、工藝品專用氧化鎂。不知道這種分類的標準和依據是什么,因為鎂水泥制品有幾十種、幾百種,難道輕燒氧化鎂也要分幾十種、幾百種嗎?再加上市場上不合格的氧化鎂繼續進行價格的無序競爭,這些都給下游工廠帶來產品不穩定的因素。多年來,地方政府也對氧化鎂生產廠家進行了多次整頓,主要出發點是從減少資源浪費、合理利用資源、環保、節能的角度出發,如何使輕燒鎂粉達標生產以滿足下游工廠需要,建立穩定原料供應基地,促進鎂水泥行業健康發展,始終缺乏監管和制度,這也是很多鎂水泥制品企業不敢和不能做大、做強的原因之一。

   從第二點來講,科學配料、合理工藝、合適養護是做好鎂水泥產品的必要條件。關于科學配料,余紅發教授在總結國家“七五”攻關的科研成果時提出的“配料原則”,是所有鎂水泥制品配料時必須遵循的原則,根據鎂水泥制品的不同品種和使用范圍,只能在這個原則范圍內靈活調整,而不能背離這個原則。

   為了便于記憶和理解這兩點中的內容,可以用一句通俗、便于記憶的詞語,就是生產鎂水泥制品必須“堅持四項基本原則”,即堅持使用達標原料的原則、堅持科學配料的原則、堅持合理工藝的原則、堅持合適養護的原則。這四項基本原則是根據鎂水泥內在的化學反應和物理特征提出的,缺一不可,相輔相成,才能較好地完成鎂水泥內部的化學物理反應過程,使產品達到較長時間的使用價值。

   鎂水泥工藝品的生產只有在達到內在的質量要求之后,再加上形式和外觀的裝飾手法,才能開發和生產出更多的品種,滿足社會的物質、文化需求。


http://www.xaqinyun.com Magnesium oxychloride cementing material (commonly known as magnesium cement), is non-combustible, non-toxic, non-radioactive, heavy metal-free, asbestos-free, and organic volatile-free. 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.
