Problems solved by technology

The above micro-nozzle ultra-high pressure water gun equipment is expensive
China Zhejiang Jinchang Company adopts the principle of high-energy laser incineration of cured film, and also manufactures and launches a laser film peeling equipment prototype. This prototype can peel off the cured film, but its efficiency is too low. A nickel mesh with a width of 1850mm can be peeled off in 4-5 hours. , and laser incineration produces a large amount of harmful gas, polluting the environment
It belongs to the two-step process of rotary screen release and bulkhead dissociation, and it is still not popularized and used

Abstract

A stripper of high temperature cured film on printing Ni screen is prepared from organic acid, corrosion inhibitor, surface active agent and expander. Its preparing method can be finalized by one step process of socking for de-filming and de-blinding so reuse for printing Ni screen in circulation can be effectively realized.

Description

Technical field: [0001] The invention relates to a technology for stripping a high-temperature cured film of a printed nickel screen used in rotary screen printing, including a stripping agent and a stripping method. Background technique: [0002] At present, textile printing methods include: copper roller printing, flat screen printing, rotary screen printing, manual platen printing, computer inkjet printing, etc., among which rotary screen printing is developing rapidly. With the mass production of small batches, multiple varieties, and fast delivery export orders, the demand for nickel screens of different specifications will increase significantly. At present, the national consumption of rotary screens is about 2-2.5 million per year. [0003] Due to the use of polymer photosensitive materials in the process of cylinder screen making, a layer of dense and elastic polymer film is formed on the surface of the nickel mesh blank. This layer of film has high strength after cu...
