Embodiment 1

[0021] The present embodiment adopts following process steps:

[0022] (A) Clean the test roll: clean the roll surface of the test roll to remove the dirt and oil on the roll surface;

[0023] (B) Make the frame: position the test roll and frame around the test roll, such as figure 1 As shown, the gap between the frame 2 and the test roll 1 is d=2cm, and the height of the frame 2 is slightly higher than the test roll 1;

[0024] (C) Preparation of silica gel and foam removal: prepare release silica gel, then put it into a vacuum machine to evacuate and exhaust the air bubbles for 2 minutes, thereby obtaining the release silica gel of the fluid;

[0025] (D) Molding: Slowly pour the above-mentioned mold release silica gel fluid that has exhausted the air bubbles from the gap between the surrounding frame 2 and the test roll 1 into the surrounding frame 2, avoiding excessive pouring speed to generate air bubbles, until the entire test roll is covered until;

[0026] (E) Curin...

Embodiment 2

[0033] The present embodiment adopts following process steps:

[0034] (A) Clean the test roll: clean the roll surface of the test roll to remove the dirt and oil on the roll surface;

[0035] (B) Make the frame: position the test roll and frame around the test roll, such as figure 1 As shown, the gap between frame 2 and test roll 1 is d=1cm, and the height of frame 2 is slightly higher than test roll 1;

[0036] (C) Preparation of silica gel and defoaming: prepare demoulding silica gel, then put it into a pressure cylinder to defoam for 3 minutes, thereby obtaining the demoulding silica gel of fluid;

[0037] (D) Molding: Slowly pour the above-mentioned mold release silica gel fluid that has exhausted the air bubbles from the gap between the surrounding frame 2 and the test roll 1 into the surrounding frame 2, avoiding excessive pouring speed to generate air bubbles, until the entire test roll is covered until;

[0038] (E) Curing: place the above-mentioned test roll after...

Abstract

The invention relates to the technical field of embossed test roller proofing, in particular to an embossed test roller silica gel proofing method, which is characterized by adopting the following process steps of test roller cleaning, surrounding frame manufacture, silica gel preparation, bubble removal, molding, curing and sampling. Compared with the prior art, the method has the advantages that the energy is saved, the environment is protected, safety and nontoxicity are realized, in addition, the method is simple, the material loss is small, simultaneously, the curing effect of the prepared silica gel is good, and the sampled samples are flat and do not have bubbles.

Description

technical field [0001] The invention relates to the technical field of proofing of embossed test rolls, in particular to a method for making samples of embossed test rolls with silica gel. Background technique [0002] The traditional embossing test roll proofing method generally adopts PVC heating roll pressing method, which has the disadvantages of toxic gas decomposed by PVC heating, large energy consumption, large material loss, etc., which is not energy-saving and environmentally friendly. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, adopt an energy-saving and environment-friendly silica gel proofing method, and solve the problems of toxic gas generation, large energy consumption and large material loss caused by the traditional proofing method. [0004] In order to achieve the above object, the present invention has designed a kind of embossing test roller silica gel proofing method, it is c...
