Coating process: production process and application of high quality grey calcium

The core tip: the main components of calcium ash are calcium oxide and calcium hydroxide (calcium oxide, magnesium, phosphorus, gypsum, alum, which were used as inorganic bonding agent in the building by the ancients) Grey calcium is strongly alkaline, pH value is 14-15 (16-19 without electrolyte) The raw material is white lime (i.e calcium oxide) calcined with high calcium limestone at a high temperature of more than 950 ℃, which is made by adding a certain amount of electrolytes and modified grinding After modification, the content of calcium hydroxide increased, the pH value decreased, the cohesiveness increased, and the water absorption decreased Calcium hydroxide is stable in the coating, not easy to thicken and crack, and has good stability Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings news: the main components of grey calcium are calcium oxide and calcium hydroxide (calcium oxide, magnesium, phosphorus, gypsum, alum, which were used as inorganic adhesives in the construction by the ancients) Grey calcium is strongly alkaline, pH value is 14-15 (16-19 without electrolyte) The raw material is white lime (i.e calcium oxide) calcined with high calcium limestone at a high temperature of more than 950 ℃, which is made by adding a certain amount of electrolytes and modified grinding After modification, the content of calcium hydroxide increased, the pH value decreased, the cohesiveness increased, and the water absorption decreased Calcium hydroxide is stable in the coating, not easy to thicken and crack, and has good stability China's high-quality limestone producing areas: Zhejiang Jiande, Guangxi Guilin, Yunnan Dali, followed by the north of the Yangtze River In the north, the calcium content of ash is low, the volume is light, and the water absorption is large; in the south, the calcium content is high, the volume is heavy, the water absorption is low, the whiteness is high, the dosage is small, and the strength is high The putty toughened ceramic powder coating is an environmental protection coating with the function of absorbing indoor carbon dioxide (the ash calcium contains calcium oxide and calcium hydroxide) It takes a long time to continuously absorb the carbon dioxide in the indoor air and convert it into calcium carbonate It can purify the indoor air These functions are gradually recognized by people The main raw materials for producing grey calcium are high calcium limestone, with oxidation content of over 55%, iron oxide content of less than 0.03%, and magnesium oxide content of 3-6% After calcination at high temperature, the content of calcium oxide is over 94% which is a good product Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
