Introduction

Regardless of what kind of abrasive and cleaning methods used in the surface treatment of steel, it is possible to form the surface of the steel after jet cleaning. Up to the irregularities of the crests and troughs. Due to this irregularity, resulting in the accuracy of the surface roughness can not be measured. because In this case, the roughness profile is proposed to be divided into recessed form (cleaned with pellet abrasive) and pointed (with sand abrasive cleaning), and the roughness Divided into "fine", "medium" and "thick" three, each grade definition see GB/T 13288.1 provisions. These surface features are considered to be given Most of the coating features are sufficient. Enough to meet most of the coating requirements. It is particularly noteworthy that the "fine", "medium" and "coarse" grades represent different ranges of roughness characteristics, depending on the spray cleaning surface Is the abrasive or abrasive. Thus, the effects of the "fine", "medium" and "coarse" grades on the coating can be achieved not only by special surface features but also ("Fine", "medium" and "thick") and the type of abrasive used. This test method requires the following details. These contents shall comply with ISO 8501, ISO 8503 and ISO 8504 parts Similar to the provisions of the standard, or the terms of the parties concerned. a) the time and position of the grade assessment, ie assessing the frequency at which jet cleaning occurs and the distance between the assessment points; b) the type of abrasive used for jet cleaning, i.e., pellet abrasive or grit abrasive or a mixture of both; c) the roughness level required for the jet cleaning surface (see note), "fine", "medium" or "thick", and the surface rust before jetting (See ISO 8501-1); d) If necessary, compare the type of sample block, ie compare sample block G or compare sample block S. Note. The corrosion grade of the steel indicates the "original" roughness of the steel surface, which will affect the roughness of the surface after cleaning. The "second" roughness is the jet The roughness formed on the basis of the "original" roughness during the cleaning process is exactly what the "second" roughness is required to use the reference comparison sample for evaluation The roughness. Due to mechanical or flame cutting, drilling and other reasons caused by the sharp edges are not in the "original" roughness within the range, before the abrasive jet cleaning Should be worn away.

1 Scope

This part of GB/T 13288 specifies the surface roughness rating visual and touch rating, using any of the provisions of ISO 8504-2 The surface roughness of steel produced by abrasive cleaning shall be assessed in accordance with the provisions of this part. The method uses ISO surface roughness comparison sample, in the field to assess the coating before the abrasive jet cleaning steel surface rough Roughness. Note. The ISO surface roughness comparison sample can also be used to assess the surface roughness of other substrates after abrasive jet cleaning, and is not limited to the determination of coating coatings Front surface. The method is applicable to the surface of the steel which is cleaned by pellets or grit abrasive, and the sprayed appearance of the whole surface is Sa2⅟2 and Sa3 in ISO 8501-1. This method is applicable to surfaces cleaned by metal or nonmetallic abrasives.
