Analysis of factors affecting the quality of materials with
Requirements. Since September 2001,
true religion outlet, production began blending material uniformity is relatively high, are 87% or more,
GHD Glätteisen günstig, so how to control the mixer is also very important. 2.2 blending raw material particle size uniformity and particle size has a lot of raw materials,
knock off oakleys, mixing of materials during the same time, will produce some of the layered material, to get quality with the material,
herve leger toronto, a mixture of materials must be strengthened to curb layered materials. While also strengthening the control of raw materials to reduce the size stratification. Layered materials and raw materials because of the particle size very close relationship. Windrow layer, so that fine material concentrated in the middle of piles, piles of large particles fall into the periphery, this creates a library fine material concentrated in the central libraries of large particles concentrated in the powder around. The vibration of layered and went to the middle of large particles, powder material to go lower. Therefore, we must reduce the material with a layered, the particles must change the current state of the particle size as even as possible, the technologically advanced countries,
Beats By Dre Headphones, most of powder particle size control in the 0.1 ~ 0.7mm. Fuyao Group Tongliao Co. powder particle size> 0.7mm and 0.7mm accounted for 5%, <0.1mm of up to 20%. Resources and Industry 2007 lime rock, hard limestone <0.1mm, 17%, particle size match is unreasonable, it is difficult to prepare a material with high quality. Fluctuations in water 2.3 water consists of two aspects: First, the mixed raw materials need to add a certain amount of water, and second, various raw materials of their own water. Add too much water, mixing well not play, plus they make too little water layer can not be restrained. If the sandstone, silica sand, soda ash water fluctuations, it is difficult to change the list of ingredients in time, will meet the expected accuracy of some impact. 2.4 The water temperature is a long-neglected problem, process calls for summer water temperature should be kept 60 ℃, winter should be maintained at above 80 ℃, Fuyao Group Tongliao Co., Ltd. changes made before the summer to keep the cold at 40 ℃ or more, maintained at about 60 ℃ in winter, this will affect the temperature of blending material, which is caused by a low degree of uniformity of material blending one of the main. Glauber's salt with the compound because of the degree of hydration and soda ash, and with the material temperature. If the blending material temperature of less than 36 ℃ or more, have varying degrees of soda ash agglomeration, in less than 32 ~ C, the sodium carbonate into the stable with the seven crystal water, while the seven crystal water of sodium carbonate at 35 ℃ When broken down into sodium carbonate monohydrate. Glauber also have such problems, 32.4 ℃ below the sodium combines with water to form stable crystal water of sodium sulfate 10, the temperature is high, becomes anhydrous Glauber's salt, more than this temperature, more water can change into a free state, to play its role, or a considerable part of the blending of water into the soda machine was immediately absorbed into the crystal water and Glauber's salt, and weaken the role of the water resistance of materials. Therefore, only guarantee a certain water temperature, to ensure the material with temperature above 36 ℃. 3 Conclusion In summary, the impact of blending material quality of many factors, but if control of several key areas, can still be prepared with high quality material. 3.1 with the uniformity of the test material should be changed from the previous day on a three-shift system and a group of some kind of measurement tests, the use of more advanced standard deviation or mean to measure with the material quality, timely find out the reasons, in order to achieve effective control of production purposes. 3.2 Strengthening the management and improvement of a variety of devices can with the material prepared by high-quality, weighing control improvements is a very important part of J. Fuyao Group Tongliao Limited, part of the introduction of weighing renovation project, and computer peripheral equipment control part of the EME entirely from the German company has introduced, co-swap material quality will play a positive role. On the other hand, the computer system, the blending and weighing focused on computer control, process more reasonable. More important point is that water control system has been greatly improved, so that the exact amount of water to ensure that the water temperature in line with technological requirements. 3.3 Preparation of materials with enhanced process management to strengthen the control of raw material particle size, the silica powder particle size in strict accordance with international standards, as far as possible to remove large particles greater than 0.7mm and less than 0.1mm of powder material , so that 0.1 ~ 0.7rain particles in more than 90%. But also to strengthen the hard limestone, limestone and other control. The size of materials used as close as possible, it is a good quality prepared with the material.
