AI Technical Summary

Problems solved by technology

[0008] It can be seen from the above data that in the past, kerosene or gasoline, carbon tetrachloride, and alcohol were used in my country to quickly restore the elasticity of the nitrile rubber blanket, but its effect was extremely low, and benzene can obtain better results, but Benzene has a low boiling point and is volatile, which affects the actual use effect

Abstract

The cleaner used for cleaning rubber insulation in hectographic printing and restoring its elasticity is liquid mixture of trichloromethane in 70-90 % and and benzene 10-30 %. It may be further made into colloid through adding gaseous reinforcing silica through stirring and still standing in iron bottle for one night. It is used to eliminate printing ink in and restore the elasticity of rubber insulation.

Description

Technical field: [0001] The invention is a reducing cleaning agent used in offset printing to clean blankets and restore the elasticity of blankets. Background technique: [0002] Offset printing belongs to pressure printing, that is, the ink on the printing plate is transferred to the surface of the blanket by pressure, and the ink on the blanket is transferred to the surface of the paper by pressure. The blanket is subjected to tens of thousands or hundreds of thousands of embossings a day, coupled with the action of various organic and inorganic chemical materials such as binders, kerosene, and wetting fluid in the ink, making the blanket particularly prone to aging and loss of elasticity. If you encounter paper creases, the blanket will be dented, so it is very important to restore the elasticity of the blanket and remove dirt such as ink on the surface of the blanket, otherwise the quality of the printed matter will be seriously affected. In the past in my country, ker...
