Embodiment 1

[0028] A detection method for detecting whether a stainless steel is polished or not, comprising the following steps:

[0029] (1) Take a sample with a length of 600mm on a steel strip with a width of 1200mm, and select 3 positions on the left, middle and right for sampling, and the distance between the left and right sides is 300mm from the edge;

[0030] (2) Cut the three samples into 20*20mm square samples, and place them horizontally at the bottom of the cold mounting mold. The cold mounting mold is a round rubber with a diameter of 30mm, and the rolling direction needs to be marked on the back of the sample;

[0031] (3) Take 5mL and 10ml of liquid curing agent and resin according to the ratio of 1:2 for cold mounting samples, then mix the two liquids, and then slowly stir clockwise for 2 minutes, and minimize air bubbles during the stirring process produced, then poured into a cold mosaic mold, and after standing for 1 hour, after the mosaic sample hardened, take out the...

Abstract

The invention relates to a method for detecting whether stainless steel is foggy or not after polishing. The method includes: taking samples with multiple lengths, and selecting three positions of left, middle and right on the samples for sampling; shearing the samples into square samples and placing the same into the bottom of a cold insetting mold horizontally; respectively taking 5mL and 10mL of two kinds of matching liquids, namely a curing agent and resin according to the proportion of 1:2, mixing the liquids, stirring slowly for 2 minutes in the clockwise direction, pouring the liquids into the cold insetting mold, allowing standing for 1 hour, and taking out an inset sample after a to-be-inset sample is hardened; opening a full-automatic grinding and polishing machine, performing flushing without loading the sample, slightly brushing a polishing cloth with a plastic brush, and cleaning the polishing cloth; taking out gold phase; detecting the surface of the gold surface.

Description

technical field [0001] The invention belongs to the technical field of detecting whether a material is fogged, and in particular relates to a detection method for detecting whether a stainless steel is polished or not. Background technique [0002] There is a demand for polished stainless steel in the market, and the material is used for appearance decoration after polishing. This application has high requirements on materials, and only a small part can meet them, while most of the materials will show pits, pinholes, impurity lines and other defects after polishing. [0003] In actual operation at present, there is no effective means to check whether the stainless steel material is suitable for polishing before feeding. The method of customer verification is often adopted: that is, the supplier first feeds the material and produces it to the specifications required by the customer, and then asks the customer to try throwing, and judge whether the material can be used for po...
