What value and collection significance? In fact, in the porcelain pieces, there is a great knowledge. China is a country of porcelain. The history of thousands of years is profound and profound. From the day of the production of porcelain, there were porcelain pieces. At that time, when people burned porcelain, they often produced a large number of defective products. The fate of the defective product is buried in the ground. In particular, a large number of ceramic tiles produced in the official kiln firing porcelain, the Royal official has been responsible for the firing of this porcelain, stationed in the kiln, supervised production, and in production, regardless of cost, Seiko innovation. For example, the emperor required this batch to make 100 pieces of porcelain, then it must be fired more than a few hundred pieces. After carefully selecting 100 pieces of porcelain, all the remaining porcelains should be broken and buried, and no one should flow into the people. People like porcelain, not only is it a precious porcelain specimen, but also a more rare collection. First, although the old porcelain piece is incomplete, its art of production and painting is still of a high level, representing the level of craftsmanship of a period. Second, it can be used as a basis for collectors to learn and appraise. Many folk collectors are Starting from playing with tiles. Speaking of this, you can't help mentioning Bai Ming, a connoisseur who plays porcelain in Beijing. The people in the line call him "white", and now the editor of the Beijing Publishing Group. “Piece White†played with the porcelain piece until it was obsessed. Whenever there was a piece of porcelain in the pocket, even sleeping at night, there were a few pieces of porcelain on the pillow. There were tens of thousands of pieces in his house. . Bai Ming's collection of porcelain films has a name. Later, he opened a museum in Chongwen District to showcase his collection of porcelain pieces. It shows the charm of the porcelain pieces. The petrolatum anti-corrosion tape is made of plastic petrolatum ester, filler, paraffin oil, special preservatives, fillers, synthetic fibers and other raw materials. Gapless flexible ribbon roll. The petrolatum anti-corrosion tape can be used together with the petrolatum topcoat, the petrolatum cement and the polymer adhesive tape to form a complete anti-corrosion maintenance system.

The mineral ester anti-corrosion tape has stable properties, no curing, no hardening, no cracking, adapts to thermal expansion and contraction of workpieces with large temperature changes, has excellent plasticity and flexibility, contains volatiles within a safe range, and is harmful to the human body and the environment. No poison. It is suitable for anti-corrosion work of metal pipes and fittings, Flanges and Valves of any regular and irregular shape. It is widely used in gas, oil, water, petrochemical plants, urban construction, ships and other fields. It is also the first choice for anti-corrosion materials for steel pipelines, cast iron pipelines, joints, tees, elbows, refueling and refueling storage tanks, special-shaped prefabricated components (such as flanges, gate valves, tees, etc.), and edge plates of storage tank bases.
Scope of application
1. Pipeline anti-corrosion
From the pipelines inside and outside the factories of large-scale chemical companies, iron and steel companies, and electric power companies, to equipment pipelines in high-rise buildings, and residential pipelines, whether it is overhead, ground, underground pipe gallery, buried or not in water, all pipelines can be used. Because it does not deteriorate even at the lowest temperature, it is suitable for corrosion protection of low temperature piping such as liquefied gas, and corrosion protection of cooling water and cold air piping.
2. Anti-corrosion of flanges, pipe fittings and welds
The petrolatum anti-corrosion system is a suitable anti-corrosion material for piping connections, valves, flanges, bolts, etc. Pipes pre-coated with plastic and bitumen, etc., can also be used for welds connected in the field.
Specifications of petrolatum anti-corrosion belt:
50mm x 10M, 75mm x 10M 100mm x 10M 150mm x 10M 200mm x 10M 300mm x 10M
The thickness and width of the tape can also be customized according to the user's specific design or construction requirements.
Features of petrolatum anti-corrosion tape:
1. The thickness is uniform, soft and easy to shape
