Zhangjiakou magnesium oxide powder desulfurization magnesium oxide manufacturer Cangzhou magnesium chloride manufacturer brine block brine powder salt brine It is recommended that new customers not blindly purchase magnesium oxide and magnesium chloride inorganic fiberglass reinforced plastic materials, do not just look at the price and ignore the quality, and buy in small quantities 2-3 Compare the products at home, and be sure to shop around. The samples some dealers send you are different from the goods you buy. To avoid losses, try to buy as little as possible each time and buy more times. Don’t worry and buy as much as you can. some. It is necessary to fully understand the performance, uses, quality, preservation, and usage methods of magnesium oxide and magnesium chloride to avoid unnecessary losses and loss of confidence in your products. Theory cannot prove practice, but practice can prove theory. Judging whether a theory is correct or not depends on practice. Theory summarizes experience through practice. When we understand things, we must continue to study and summarize them from the surface to the essence. Practice is the source and foundation of understanding things. In fact, the shelf life of lightly burned magnesium oxide powder is very short and difficult to store. Over time, it will affect the quality of the product. In areas with hot and humid climate, magnesium oxide will agglomerate in about 15 days and cause waste. If customers don't ask, merchants will not tell you these things. The reason is simple, it will affect sales. Sea crystal magnesium chloride brine blocks can be stored for a long time without affecting the quality. Tianjin Shengfang, the hometown of popular furniture, once had a customer who wanted to make an artificial marble coat rack base. The result was very unsatisfactory. Magnesium oxide molded slowly and had no strength. When I asked the merchant, I couldn't find the reason. I once lost confidence in the product. ; later contacted me through the Internet and asked me the reason. When I learned that the raw material magnesium oxide and magnesium chloride was purchased from XXXXXX, a city in Shijiazhuang (omitted to avoid disputes), I understood everything because several customers had reported the same thing before. I told him the reason was that the raw materials magnesium oxide and magnesium chloride were unqualified. He wired me money with a glimmer of hope. I sent him several generations of samples and called him the next day to say they were good. A long-term cooperative relationship was then established. Some irresponsible businesses ignore the interests of customers and cause losses to customers. Boss Zhou of a mold factory in Botou City, the hometown of molds, encountered this problem. He purchased 40 tons of magnesium oxide at a certain place because it was used in the summer. The magnesium oxide started to clump in less than a month and could no longer be used after 40 days. I called the merchant and asked the dealer, who said it was caused by improper storage and humidity. When purchasing, it was told that the shelf life of magnesium oxide was three months. How much magnesium oxide should I buy per ton? The difference was dozens of yuan. Boss Zhou considered that this batch of goods could be used up in more than three months and saved more than 2,000 yuan. As a result, he lost tens of thousands of yuan; sometimes theory and practice run counter to each other, and there is no experience gained from books, leading to failure. Only through experience can we gain lessons. The acquisition of experience is the result of paying a price. Take magnesium oxide as an example. Many people I don’t know called me to ask some questions. They reported that the magnesium oxide they purchased had an active content of 85% and an active content of 65%. It solidified very slowly and had poor strength. I answered them one by one. After all, The reason is that although magnesium oxide can reach the highest content, it is not necessarily easy to use. One reason is that the heat of magnesium oxide was not controlled well during the firing process. It was over-burned or the heat was not enough. Zhangjiakou magnesium oxide powder desulfurization magnesium oxide manufacturer Cangzhou magnesium chloride manufacturer brine block brine powder salt brine. Another reason is that the content is not reached at all, or the ratio of magnesium oxide and magnesium chloride is unreasonable, or the storage time is too long and exceeds the shelf life. On the National Day this year, a client from this city came to me with a sad face and said with a northeastern accent: "The leverage land that we used to build in Baoding is no longer the same when we come to Baoding. I really don't understand. Please give it." Let me take a look! As he talked, he took out the handicrafts he made and a small bag of magnesium oxide and a small bag of magnesium chloride samples from the car. I first looked at the magnesium oxide, which was whiter and thinner than mine. It looked pretty good. I asked him where he bought it from, and he said he bought it from a large XX chemical store in this city. The magnesium oxide had agglomeration when he bought it. He was afraid that there would be quality problems and asked the boss about it. What's going on? The boss said it was just a little damp and it would be fine. It wouldn't affect the use. I said you were deceived by the boss. Just as he was talking, a familiar minivan drove into the yard. I went out to greet Xiao Li and brought Xiao Li in. I recommended him to Northeast China, and I said you guys should talk first while I went to load Xiao Li’s car. I took my family to load the car and sent Xiao Li off. Before I could say anything when I got back to the house, Dongbei said I knew what was going on. I heard Xiao Li say that he had bought goods from that chemical store before, because the quality was so bad. There is no guarantee of good or bad times, so I switched to you later. I felt relieved when I bought it this time... I felt happy as I wiped the sweat from Dongbei's face after seeing Dongbei go.

Magnesium oxide is in normal condition In this case, the shelf life is 3 months in winter and 1 month in summer, and the ratio of magnesium oxide and magnesium chloride is unreasonable. It was only half a month in humid areas. Later, Boss Zhou contacted me through a friend’s introduction. I explained the situation to him and suggested that he choose the purchase volume according to the climate. After that, we established a cooperative relationship. The quality of magnesium oxide produced by most manufacturers is extremely unstable. Sometimes good or bad, the main reason is the selection of materials, the temperature during firing, and poor control of the heat. Over-burning will solidify slowly or even not at all. The heat is not strong enough. Magnesite cement is heavy and lightly burned. Magnesium oxide and magnesium chloride solidify slowly or not at all. The reasons for solidification are: 1. The active ingredient of heavy light-burned magnesium oxide is too low, 2. The temperature of magnesium oxide is too high during the firing process. The firing time is too long, 3. The storage time of the finished product of heavy light-burned magnesium oxide Too long will reduce the activity of magnesium oxide. 4. The temperature when producing magnesite products is lower than 15 degrees. 5. The proportion of magnesium chloride and water is low. 6. The magnesium content of heavy light burnt magnesium oxide is lower than 60% and the active ingredient is lower than 30%: Magnesite cement will solidify slowly or not at all. The formation of magnesium oxychloride cement mainly relies on the reaction between the active magnesium oxide in magnesium oxide and the chloride ions in magnesium chloride. If there are too many burnt products in magnesium oxide, the active magnesium oxide will decrease and react with the chloride ions in magnesium chloride. During the reaction process, there is not enough active magnesium oxide to react with chloride ions, which will prolong the generation time of magnesium oxychloride cement, leading to the occurrence of retardation. The symptoms at the same time include halogen return, alkali return, etc... Last year, Manager Wang from a building materials factory in Baoding came to me and told me about his situation. When producing magnesium oxide boards, it sometimes took 4 hours to solidify and demould, and sometimes it took 8 hours to solidify and demould. As a result, he was unable to arrange production on time. I told him Explain the reasons and sign a long-term supply contract; Magnesite inorganic FRP material technical consultation 18931383092 Manager Zheng. Customers often call to learn about magnesium oxide, magnesium chloride light burnt powder, halogen blocks, halogen sheets, magnesia inorganic FRP products, chicken house boards and various I answered all the crafts technology one by one. I missed a lot of things because of this, but after a long time I felt something was wrong. I always wondered if there was a better way to help more people who wanted to make (magnesite inorganic fiberglass products) )friend! If you want to make magnesite products without taking any detours, please cooperate with me. Society develops in contradictions, and human beings make progress in exploration. I want to help more friends, but describing it in words is abstract and not as clear as language. I will try my best to describe it in words, hoping to help make magnesite inorganic fiberglass products. Friends have one more way to make money, " width="497" height="497" alt="" /> Preparation of Zhangjiakou magnesium oxide powder desulfurization magnesium oxide manufacturer Cangzhou magnesium chloride manufacturer brine block brine powder salt brine There are two water methods: (1) Magnesium chloride hexahydrate that is well packaged and has not absorbed moisture can be directly prepared into a solution with a specified concentration. For example, the magnesium chloride content of the chicken house board in the purchased magnesium chloride hexahydrate is 44.9%. To prepare 100KG of 23% MgCl2 solution, MgCl2· is required. ;How much KG is 6H2O? How many KG of water should be added? After calculation, After a few hours, use a Baume meter to measure the Baume degree of the solution and record it, or use a density meter to measure the specific gravity of the solution at this time. The preparer can use a Baume meter or a density hydrometer, or they can compare the two. The Baume concentration value and the density meter value are corresponding. If the difference between the two values is too large, one must be inaccurate. The correspondence between Baume degree value and specific gravity value is as shown in Table 1. Table 1: Corresponding values of Baume degree Be′ 23 24 25 26 27 28 29⑵Use this book When batching the deliquesced and semi-dissolved magnesium chloride hexahydrate, dilute it directly with water and dissolve it to the last prepared Baume degree or specific gravity count, which is a 23% content MgCl2 solution. It should be pointed out that: ① Because the MgCl2 in magnesium chloride hexahydrate The content of impurities is also different (44.5-46.5%). Therefore, when different magnesium chloride hexahydrate is used to prepare a solution with the same percentage content, the Baume meter indication value will be different. ② The Baume meter should be selected with a graduation value of 20-30. , which is more accurate than 0-30 and 0-50. The density meter should use a graduation value of 1.20-1.30. ③ There will be a difference of 0.2-0.3 in the reading of the Baume meter between the solution that has just been stirred and the solution that has been allowed to stand and the dissolved gas has been released. The Baume meter reading measured after standing should prevail. ⑶ Magnesium chloride hexahydrate with excessive KCL and NaC1 content must not be used. The raw material standards for magnesium chloride hexahydrate are implemented in accordance with WB/T1018-2002. 3. Reasonable molar ratio of ingredients Inorganic fiberglass magnesite artificial stone handicraft raw materials Zhangjiakou magnesium oxide powder desulfurization magnesium oxide manufacturer Cangzhou magnesium chloride manufacturer brine block brine powder salt brine
