Instrument letters 232 fineness dispersion measurement principle:

Fineness gauge #232Used for measuring fineness of coatings, which will test the paint into a wedge-shaped, by visually identifying coatings particle size greater than wedge height position, on the sample surface smooth and uneven line position read out the position groove depth, the value for the fineness of coatings.

Design:

#232 fineness gauge consists of a hardened steel, hardened steel through special treatment, guarantees good dimensional stability, the hardened steel cutting out two precision machined wedge-shaped grooves. Groove on one side of the unit is mM height of the slots, the corresponding Hegman Scale (HS ) On the other side, other scales can also be customized according to the requirements, the most commonly used between the fineness of the unit conversion, see the following chart: standard #232Fineness measurement range 15/25/50/100mM, in the scope of supply includes a for films, straight-edged scraper scraper.

Measuring procedure:

Wedge grooves deeper into one end of a sufficient number of Testing of materials , Be careful not to produce bubbles, holding scraper, perpendicular to the fineness and slots will be Material Scraped to a narrow Groove of side smoothly, the travel required 1-2Seconds to complete.

Assessment should be blowing out 3Second, when line of sight is perpendicular to grooves, from the 20-30To find out where particles or scratches appear, that corresponds to the location of groove depth is the fineness of the test material.

Maintenance:

Fineness gauge #232Clean with solvent immediately after use, do not use hard to clear the remaining paint. Scraper using straight edge will be continuous wear, so when using minimum force, and after a certain time to check, place the scraper in the spirit level (such as along the fineness of the vertical direction), then according to the principles of light transmission check.
