Below is an introduction to a more advanced type of paper: VCI rust preventive paper VCI rust preventive paper is an industrial paper, generally used for the outer packaging of various metals, playing an extremely important role in rust prevention for metals.
Among many materials in the packaging industry, VCI rust preventive paper It is a high-tech product, with its core technology embodied in VCI (Volatile Corrosion Inhibitor). VCI technology is an integrated technology combining organic synthesis, physical chemistry, corrosion and protection, metal materials, paper processing and polymers. Due to the presence of this VCI, the vapor phase rust inhibitor achieves good rust prevention function. Depending on the VCI rust preventive paper system, there are significant differences in safety, efficiency, environmental protection, and applicability, which are reflected in products of various forms and functions.
VCI rust preventive paper Advantages:
1. Achieves oil-free packaging, without coating, degreasing, and cleaning processes, saving time and costs.
2. Effective rust prevention can be achieved even without direct contact with metal, especially suitable for metal parts with complex appearances.
3. Combines both rust prevention and packaging effects.
4. Compared to vacuum packaging, it is cheaper and easier to use.
5. Clean, harmless, non-toxic, environmentally friendly and safe. SGS certified and meets RoHS directive requirements.
Product Forms: VCI rust preventive paper Soaking it in plain weave neutral base paper is for rust prevention purposes. The purpose is to compound a single or double layer of PE layer and woven layer in the neutral rust preventive base paper to improve waterproofness and strength. Printing services can be provided according to user requirements.
Metal Protection Range: According to the material of cold-rolled steel sheets, it is divided into VCI rust preventive paper for cold plates, vapor phase rust preventive paper for galvanized plates, VCI rust preventive paper for silicon steel plates, and vapor phase rust preventive paper for tin-plated plates. Strictly speaking, they should not be confused with each other.
Product Applications: Widely used in the storage and rust prevention packaging of metallurgical cold-rolled materials such as cold-rolled plates, galvanized plates, silicon steel plates, and tin-plated plates. During packaging, the periphery uses PM, PC, and PD structured fabrics to reinforce the vapor phase rust inhibitor, and the core uses PF structured vapor phase rust inhibitor. The overlapping parts of the two materials can be sealed with tape. Furthermore, iron plastic plates are used to protect the outer packaging material.
