MODERNER QXD-50 Large double-channel Fineness gauge measurement range 0~50μm

overview

QXD 50 large double-slot Fineness of Grind Gauge is a large double-slot Fineness of Grind Gauge with a chute width of 25.4mm. The fineness measurement range of QXD 50 is 0~50 microns, and the division value is 5 microns.

In the MODERNER, there are various specifications for the research and development and design of the Fineness of Grind Gauge, including general single and double grooves, wide grooves, and large and wide grooves. This large double-slot Fineness of Grind Gauge is a Fineness of Grind Gauge with a large chute width. There are two models, QXD 25 and QXD 50. The corresponding measuring ranges are 0~25 microns and 0~50 microns respectively. The design has Two wider chute with a width of 5.4mm. Applicable to some users with special needs.

The large double-slot fineness scraper QXD 25/50 conforms to the national standard and is mainly used to measure the fineness of particles such as pigments and impurities in paints and paint pastes. The large double-groove fineness scraper is made of stainless steel, and it is equipped with a 95mm scraper. The width of the chute is larger than that of the general fineness plate. The fineness scraper is designed and manufactured according to JJG (Chemical) 018-96 "Grindometer" and its GB/T1724 standard of the Ministry of Chemical Industry of the People's Republic of CHINA for the verification of special equipment for coatings.

Features

Steps for usage

(1) Before use, the QXD 50 Fineness of Grind Gauge should be soaked with a suitable solvent, including the scraper and the bottom, and dried with cotton yarn, and the sample that meets the product standard viscosity index should be fully stirred with a paint knife.

(2) In the deepest part of the groove of the QXD 50 large double-groove Fineness of Grind Gauge , drop a few drops of the sample, which can fill the groove and be slightly redundant.

(3) Hold the scraper with the thumb, index, and middle fingers of both hands. Place it horizontally on the upper end of the double-groove Grindometer, make the scraper perpendicular to the surface of the Grindometer, and pull the scraper from the deep part of the groove to the shallow part at an appropriate speed, so that the paint sample fills the groove without leaving any residue on the plate. There is excess paint.

(4) Immediately (not more than 5 seconds) after scraping, pinch the fineness gauge horizontally and tilt it so that the line of sight is 15-30° from the groove plane and observe the scale value of the uniformly exposed particles in the groove. The reading value is The fineness value of the measured object.

Precautions

(1) Do not scratch the surface of the Grindometer and the scraper

(2) Clean the QXD 50 large double-slot Grindometer immediately after use and apply Vaseline to prevent rust

(3) When measuring the fineness, the clear oil that meets the product standard should be adjusted before measuring

(4) Regularly (one year) check the knife edge and the straightness of the fineness gauge, and if it is found to be uneven or the Grindometer is worn, it needs to be calibrated by the national metrology and verification agency before it can be used.
