Abstract
Description
technical field
[0001] The invention relates to an industrial paper packaging bag, in particular to a surface anti-corrosion air-permeable nano material industrial paper packaging (valve port) bag and its application. Background technique
[0002] At present, there is no paper packaging (valve port) bag capable of packaging PH=3-4 and PH=9-10 nano-scale materials with strong corrosiveness. Such packaging (valve port) bags are all imported, and the cost Higher; while ordinary industrial paper packaging (valve port) bags without anti-corrosion treatment can be corroded into paper scraps by corrosive media, lose their packaging capabilities and may cause economic losses.
[0003] When the material in the packaging bag is a special nano-scale solid material - fumed silica, since the material just loaded into the packaging bag contains free chlorine and some hydrochloric acid gas, the pH value is between 3-4 at this time. The corrosion of kraft wrapping paper is very serious, an...
