The patented technology of anti-rust steel rust-proof wrapping paper invented by the top professional and technical talent in Qinhuangdao City, Professor Zheng Dong of the Beidaihe Branch of Tianjin University of Commerce, has recently been protected by the national intellectual property rights and will be put into production in the near future.
During the storage, transportation, and use of metals, due to the effects of water vapor, oxygen, acids, alkalis, salts, and carbides in the environment, physical and chemical changes (ie, corrosion) occur at a certain temperature and time. ). Corrosion of metals can result in the loss of metals and the degradation and loss of the function of metal components. Currently used in the prevention of metal corrosion of wrappers, gas-phase and contact type, but all belong to the general-purpose metal rust-proof paper, stainless steel is not special rust-proof paper, stainless steel products are not suitable for packaging. The new type of metal rust-proof wrapping paper and patented “stainless steel rust-proof paper†are patented products developed specifically for stainless steel rust-proof packaging protection.
It is the "stainless steel stainless steel rust enemy agent" added to the appropriate stainless steel "paper base", so that the paper on the stainless steel rust from the special prevention and protection functions. The paper can be suitable for rust-proof packaging of stainless steel plates, wire rods, mesh materials, parts and appliances, not only has good anti-rust effect, but also has no toxicity and pollution during the production process of rust-proof paper, and does not change the equipment of the original paper mill. And conditions, only some changes in some aspects of the production process.

Copying is not to draw an extremely realistic picture, but to learn in the process of copying, why the color relationship in this place is like this, why this kind of physical structure is used here, and so on, we need to think about it. Using the copy table to copy, can make the copied works more intuitively displayed in front of you, light, color, space, body structure, material texture, etc., clearly feel the thickness change of each line of the work, the color gradient process, And then in the process of copying the analysis and understanding thoroughly.
