Moisture-proof agent also known as Moisture-proof desiccant So, what is the composition of a moisture-proof agent?

Moisture-proof agent Composition: Mostly calcium chloride and calcium carbonate, which can be sun-dried or baked after water absorption. Also known as anti-whitening agent. It is a colorless and transparent liquid composed of a mixture of esters, alcohols, and ketones, etc., which have higher boiling points and slower volatilization rates. When used with nitrocellulose lacquer thinner, etc., it can be used in high-humidity environments. Used to prevent the whitening of nitrocellulose lacquer films Moisture-proof agent It is called nitrocellulose lacquer moisture-proof agent; the moisture-proof agent used for polyvinyl chloride is called polyvinyl chloride lacquer moisture-proof agent.

Technical indicators of moisture-proof agent: 　　

1. Appearance: Milky white or light yellow blue light emulsion

2. PH value: 8.0-9.0

3. Properties: Non-toxic, odorless, non-corrosive, easily soluble in water, pollution-free, and easy to use.

4. Performance: When applied to the surface of paper products and the paper products are placed at a 45° angle and poured into running water, it forms obvious beads and does not penetrate for a long time.

Main features of moisture-proof agent: 　　

High stability: OPE moisture-proof agent adds special emulsion stabilizers and dispersants, and adopts effective phase inversion emulsification technology, and the centrifugal test is stable and durable.

Strong moisture-proof performance: Because the particles of this product are fine and the surface area is large, after demulsification, it can be uniformly adsorbed on the fiber surface, and after drying, it can form an extremely thin water-repellent layer, which has excellent moisture-proof function.

Non-polluting: This product is an emulsion with water as the dispersion medium, non-toxic and odorless. During use, no harmful solvents are volatilized, it is harmless to the human body, and does not pollute the environment.

Other products currently on the market for drying and moisture-proof:

1. Quicklime desiccant

2. Silica gel desiccant (moisture-proof beads)

3. Mineral desiccant

Silica gel Moisture-proof agent is a highly active adsorbent, usually obtained by reacting sodium silicate with sulfuric acid and undergoing a series of post-treatment processes such as aging and acid pickling. Silica gel is an amorphous substance with a chemical formula of mSiO2·nH2o. It is insoluble in water and any solvent, non-toxic, odorless, chemically stable, and does not react with any substance except strong alkalis and hydrofluoric acid. The chemical composition and physical structure of silica gel determine its many characteristics that are difficult to replace by other similar materials
