Vapor phase rust-proof paper is a special rust-proof packaging material made of a special neutral paper as a base material, coated with a special substance of different groups-VCI, and processed through a series of post-processing.
Among the many materials in the packaging industry, VCI paper is a high-tech product, and its core technology is reflected in VCI. VCI technology is a comprehensive technology integrating organic synthesis, physical chemistry, corrosion and protection, metal materials, paper processing, and polymers. Different VCI systems have large differences in terms of environmental protection and applicability, so they are reflected in various forms and functions.
The object of protection: hot and cold rolled substrates and various coated plates in steel plants.
Product form: VCI is impregnated on plain weave neutral base paper for rust prevention purpose, and a single or double PE layer and knitted fabric layer are compounded on the neutral rust base paper for waterproof and increase strength purpose. It can provide printing services according to user requirements. Protective metal range: According to the material of cold-rolled steel plate, it is divided into vapor-phase rust-proof paper for the cold-rolled plate, vapor-phase rust-proof paper for the galvanized plate, vapor-phase rust-proof paper for silicon steel plate, and vapor-phase rust-proof paper for tinning. Strictly speaking, they cannot be mixed with each other.
Product application: It is widely used for storage and transportation of metallurgical cold-rolled sheets such as cold-rolled sheet, galvanized sheet, silicon steel sheet, and tin-plated sheet. When packaging, PM, PC, PD structure fabric reinforced vapor-phase rust-proof paper is used on the periphery, and PF structure vapor-proof rust-proof paper can be used as the inner core. The overlap of the two materials is sealed with tape. Then the iron plastic plate is used to protect the outer packaging material.
