Zhengzhou Ying-jeou rust-proof paper, Ltd. (formerly: 'Yellow card' rust-proof paper), was founded in 1986, is engaged in the research and development of rust-proof paper packaging. Metal rust problem has been everyone's attention, every year a large number of metal rust was abandoned because of Hubei kraft paper manufacturers, resulting in a lot of waste of resources. Now, rustproof metal technology has been further improved, in addition to the traditional metal surface rust treatment done, more manufacturers have begun to choose to use rust-proof paper to achieve the purpose of rust. Antirust antirust principle is simple kraft paper, it is the use of volatile corrosion inhibitor VCI can continue slowly at room temperature gasification principle volatile, making it out of the volatile corrosion and gas can be adsorbed on bare metal surface, thereby to form a stable protective film is one to two molecules thick, to block oxygen, moisture and other environmental atmosphere corrosion of metals. And vapor phase corrosion inhibitor is capable of continuing volatile VCI kraft paper company in Hubei, it is possible to always be in a confined space "saturation" state, so as to achieve long-term, stable and good anti-corrosion effect. Zhengzhou Ying-jeou rust-proof paper, Ltd. (formerly: 'Yellow card' rust-proof paper), was founded in 1986, is engaged in the research and development of rust-proof packaging paper has three decades of experience. Independent R & D, production and management system. Density and computational methods VCI paper, VCI cut a square pattern, the pick of the four corners and center of the measuring point, after using micrometer calipers to measure the thickness values ??were averaged Hubei packaging, kraft paper manufacturers, and then use electronic weighing scales, the weight divided by the product of the pattern size and thickness, the resulting figure is the density of the VCI paper for example as follows: VCI pattern size is: 100mmx100mm, the average thickness of 0.1mm, weighed 0.5g, the VCI paper density: 500. Hubei kraft paper manufacturers, rust-proof paper] [Ying-jeou (certified), Wuhan, Zhengzhou Ying-jeou by Kraft Paper Co., rust-proof. Rust-proof paper, Ltd. Zhengzhou Ying-jeou (www.yjfxz8.com) is Zhengzhou, rust-proof paper leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Rust-proof paper in English nine leadership with the staff warmly welcome all inquiries negotiations to create rust-proof paper Ying-jeou a better future.
