Factors affecting the Drying of Ink Oxidized Conjunctiva.Desiccant, the oxidation rate of

dry vegetable oil is generally very slow, and a certain amount of desiccant should be added

to regulate it. Different amounts of desiccants, such as metal cobalt, manganese, lead salt,etc.

are added to the special binder as oxygen carriers. These carriers become the contact agents

in the oxidation polymerization process of unsaturated components in the binder, thus

accelerating the oxidation polymerization reaction speed of the binder and

accelerating the drying of the ink.

Factors affecting the Drying of Ink Oxidized Conjunctiva.Pigments and inorganic pigments,

except that carbon black is an amorphous carbon element, most of them are metal salts,

such as chrome yellow, iron blue, etc., which can promote the drying of ink. They are desiccants

themselves, and the ink prepared with them can dry quickly. Most organic pigments have no

effect on ink drying, especially when there are phenol, phenol, amine, aniline, naphthol and other

groups in the molecular structure, which can inhibit the oxidative polymerization reaction of

the binder. They are inhibitors of oxidative polymerization drying. The ink prepared with them

has a relatively slow drying speed and is generally used for penetrating drying ink.

Factors affecting the Drying of Ink Oxidized Conjunctiva.The temperature and humidity of

the working environment, the temperature rise accelerates the oxidation conjunctival reaction,

and the drying time is generally reduced by half for every 10 ° C rise.

The increase of ambient humidity will slow down the drying rate.
