Daye Peak Held Low-alkali Cement Production Seminar
News In order to ensure the quality of low-alkali cement to meet the requirements of key project contract indicators, to increase the market share of "Peak " brand cement high-end products, 5# December, Daye Peak Cement Company organized a special seminar, special discussions on low-alkali cement ingredients, production, quality management and other matters.
low-alkali cement refers to cement with low content of alkali metal oxides (potassium oxide and sodium oxide) (total alkali content is calculated as equivalent sodium oxide (Na2O + 0.658K2O ), and low-alkali cement requires total alkali content lower than 0.6% ). In engineering construction, the alkaline substance in the concrete raw materials chemically reacts with the active ingredients to generate swelling substances or water-absorbing swelling substances, which in turn causes the concrete to produce internal self-expansion stress and crack, which is called "alkali aggregate reaction " (abbreviated as AAR) . Because the alkali aggregate reaction generally occurs gradually after several years after the concrete is formed, the durability of the concrete is reduced as a result, and in severe cases, the concrete will lose its use value. Moreover, because the reaction occurs in the whole concrete, the damage caused is difficult to prevent, prevent, repair and rescue, and is called "concrete cancer " . Therefore, many projects, especially railways, bridges and other large-scale projects require the use of low-alkali cement. Since its production, Daye Peak has participated in the construction of key projects in many countries, provinces and cities, and has accumulated a lot of experience in the production of low-alkali cement.
The production of low-alkali cement requires the use of low-alkali clinker, low-alkali gypsum and low-alkali mineral admixtures. Low alkali clinker must be produced with low alkali limestone and other low alkali raw materials. At the seminar, Daye peak management team and quality control department, manufacturing department, mining and other relevant personnel attended. Combined with the limestone resources and early production experience of Daye Peak Mine, a detailed and comprehensive discussion was carried out. The Quality Control Department puts forward a plan for the batching scheme and process control of low-alkali cement, and formulates detailed alkali control measures from the work links such as the quality control of mine limestone, the substitution of low-grade sandstone for clay batching, and the adjustment of mixed material varieties. The mining department, manufacturing department and other relevant departments put forward their views and suggestions on the problems that may be faced in the actual production process.
Daye Peak requires all relevant departments to attach great importance to and cooperate closely, optimize the production organization in strict accordance with the predetermined quality control index requirements, and minimize the adverse factors affecting the operation quality of the kiln, so as to ensure the high quality and high yield of the kiln, ensure the stable production of low alkali cement, and provide customers with high-quality products.

"Active Dendrobium superfine powder" technology patented
The technical achievement of Jianfeng Health Technology Company "a preparation method of active Dendrobium officinale superfine powder" has recently obtained an invention patent, with the patent number ZL 201510242263.8 and the validity period of 20 years. Compared with the traditional method, the Dendrobium officinale powder prepared by this technology fully retains the original drug activity, and the bioavailability is doubled. Dendrobium officinale is known as "plant gold". It has the effects of nourishing the stomach, nourishing yin and clearing heat, moistening the lung and kidney, and strengthening the waist. The common traditional Chinese medicine on the market is made of fresh Dendrobium officinale while heating. It is twisted into a spiral or spring shape and dried and processed. People usually smash the iron maple bucket into fine powder and take it together with American ginseng fine powder. However, conventional drying will cause the active ingredients and effective ingredients of Dendrobium officinale to be damaged, and the taste, color and appearance will change. In addition, the crushing time is relatively long, and some materials are heated relatively high during crushing, which further leads to the decrease of its efficacy, and the rehydration of the processed fine powder is also relatively poor, thus affecting the effect. The patent achievement of "a preparation method of active Dendrobium officinale superfine powder" effectively solves the above-mentioned drawbacks. This method pulverizes Dendrobium officinale after vacuum freeze-drying by a low-temperature ultra-high-speed airflow pulverization process, and controls the pulverization temperature to 20 ℃ and below, thus avoiding quality deterioration reactions such as oxidation of active ingredients, destruction of volatile oil and other heat-sensitive substances during the pulverization process of Dendrobium officinale. Its fineness can reach more than 95% and its particle size is less than 20μm, which improves the fineness of traditional Dendrobium officinale powder.
