VCI Master batch, a base material used for producing VCI plastic film (a kind of functional plastic film which can be applied to the packing and antirust of ferrous and nonferrous metals), is a functional resin concentrated and refined from PE, compound VCI and multi additives with specific processing technology.
1. Weigh and take respectively the resin and new PE granules according to the established formulation proportion, then mix them evenly and feed them for film blowing production.
2. Set the temperatures for the fusion range and mould head range of a blow molding machine according to the requirements, otherwise they will have effects on the quality of VCI film.
3. If it is necessary to produce colored VCI film, control the addition amount of the colored resin granules in the range of the established proportion and its PH value shall be neutral.
4. Seal again the original packaging in time after taking the resin granules to avoid its being affected with damp.
The VCI Master batch is applicable to ferrous metal, alloy steel, cast iron, copper, brass, bronze, plated metal, zinc and its alloy, chrome and its alloy, cadmium and its alloy, nickel and its alloy, tin and its alloy, and other metal materials and their products.
With sealed package, it shall be kept in a cool, dry place, away from sunshine and no contact with sources of ignition and corrosive materials. The quality guarantee period shall be twelve months from the date of delivery.
Since VCI film prevents metals from rusting by means of the continuous and adequate VCI gasified antirust particles volatilized from VCI contained in the film, thin film means less VCI content which may influence the usage effects of the product. Therefore, on the basis of our practical experience, the recommended standard thickness of the VCI film made from VCI antirust resin shall beｕ100um (0.10mm, commonly referred to as 10 decimillimeter).
