There are two specific methods for the production of contemporary traditional ceramics, dry and wet methods. The dry mud sand raw material is directly processed into molding material and then sent to firing, which is called dry method. The amount of water is directly added to mud sand and grout to make the mud and then processed into a molding material and dried and then sent to the firing, the so-called wet method. The vast majority of ceramic production in the contemporary world is produced using wet processes, and it is certainly scientific and cost-effective. However, as long as the wet process is used, there is a problem of dehydration and drying, that is, the problem of drying wet materials and drying them. Wet-drying is essentially the reduction of water, called dehydration or drying. For example, the mud containing more than 32% water through pressure filtration to obtain a mud cake is dehydrated; the slurry is directly passed through a spray dryer to obtain a granular powder containing about 6% of water for pressure molding and drying; about 18% of the water content is contained The body or the water containing about 6% of the body through the dryer to reduce the water content of the body to the required moisture before entering the kiln is dry. Under normal circumstances, the industry often refers to dehydration at room temperature as dehydration, and dehydration using thermal engineering methods as drying.
Mixing, dewatering, and drying are processes that cannot be bypassed in the production of modern ceramics industry. They also require energy consumption, damage to the environment, and have an important impact on product quality, plant occupancy, production line investment, and productivity improvement. The development of new-type industrialized production, clean production and production line should be listed as an innovative topic.
Since ancient times, the longest, cleanest and most convenient way to dry is to use solar energy. Drying is one of the ways. The future of dry energy solar energy development should be ranked first and have good prospects, currently only cost issues.
One of the lagging points in China's ceramic production is the lack of development of dehydration and drying technologies and equipment.
Complicated Steel Structere
Light steel structures are not strictly defined and can be distinguished by the cross section of the main structural members. Therefore, the following structure can be called a Light Steel Structure : (1) a structure made of cold-formed thin-walled steel;
(2) a structure made of hot-rolled lightweight steel; (3) a structure consisting of welded and high frequency welded lightweight steel;
(4) a structure made of round tubes, square tubes, rectangular tubes, etc.;
(5) a structure made of welded steel plates;
(6) a structure made up of various components.
1, workshop crane lifting weight: greater than or equal to 25 tons, can be considered for steel structure. 2 per square meter, the amount of steel: greater than or equal to 50KG/M2, is considered to be a steel structure. 3, the main component plate thickness: greater than or equal to 10MM, light steel structure with less. In addition, there are some reference values, such as the cost per square meter and the weight of the largest component
Light steel structure design code (Shanghai standard) is to distinguish between light steel and general steel; light steel structure housing is not strictly defined, usually can be used to distinguish the main force components of the cross section. Therefore, the following structure can be called the light steel structure: (1) structure made of cold-formed steel; (2) made of hot-rolled steel structure light; (3) the welding structure of the light type steel by welding and high frequency; (4) the structure of round tube, square tube, rectangular tube etc. made; (5) structural components made of thin steel plate welded made; (6) the structure made of all component composition. Determination of the structure of steel and steel structure does not have a unified standard, many experienced designers or project managers are often not completely clear, but we can take some data into account and judge: 1, workshop crane lifting weight: greater than or equal to 25 tons, can be considered for steel structure. 2 per square meter, the amount of steel: greater than or equal to 50KG/M2, is considered to be a steel structure. 3, the main component plate thickness: greater than or equal to 10MM, light steel structure with less. In addition, there are some reference values, such as the cost per square meter and the weight of the largest component
