DuPont Impact Tester

This tester is designed to test the impact endurance of coating material after coated Put the coating face of specimen upwards, and connect it with specified radius Impact Head, then use a certain weight to impact the Impact Head on a fixed height, afterward, check the damage or deformation of coating .

To do an impacting test for painting and coating materials is to use an impacting head with various round angles to touch the specimen in the beginning, and then a selected weight free dropping from a certain height to hit the impacting head to impact the specimen. Running the same way to test three more specimens, and put and leave them for an hour, and then watch if there is crack on the painting.

The RK instrument for quick, repeatable and highly accurate
proofing and colour-matching of all types of litho, weboffset, letterpress inks and varnishes. The Paste Ink Proofer
is unique in featuring automated operation, eliminating the need to weigh or measure ink samples.

MAIN FEATURES
* Accurate proofs produced in a single operation
* No messy weighing or measuring of inks, unlike other proofers
* Two inks may be proofed simultaneously for comparison
* Inking/cleaning cycle completed in only 2-3 minutes
* Multiple proofs easily obtained using any substrate
* Reduces press down time
PASTE INK PROOFER SPECIFICATION
Substrate size : 124mm wide x 300mm long
Print size : 75mm x 245mm (Max)
Speed range : 5-40m/min
Printing pressure : 0-150 Newtons/cm
Blanket roller : 70° shore hardness, suitable for all types of paste inks



PRINCIPLE USES
The PIP has many applications. It is an essential tool for both ink makers and printers, providing the simplest
method of producing high quality proofs. These proofs may be used for computer colour matching data, customer
samples, or to test for colour, gloss, opacity, penetration, drying, set off, rub and abrasion resistance. Pigment and
other raw material suppliers will find the PIP invaluable for assessing their products.

INK FILM
The ink film on the blanket roller is accurately metered by a screen engraved on the inking roller. The inking roller has a polished ceramic surface that is covered in uniform cells that have been engraved using a laser. The number and depth of these cells are accurately controlled and contain a constant volume of ink. The following table gives the approximate ink film weight applied when using a typical offset ink.

All inking rollers are supplied with a proof and a record of the actual film applied using a typical offset ink. Inking rollers to give other ink films may be made to order. The ceramic surface is virtually indestructible in normal use and is therefore ideal for use as a
“standard” for quality control purposes.

Automatic Drying Tester for Ink

Automatic Drying Tester for ink is applicable to test the ink drying time. This tester consists of a rotating cylinder, a weight wheel and touch screen. When it work, the rotating cylinder rotates at constant speed, meanwhile the weight wheel moves in line along the cylinder axis at the constant speed. Applicate the sample on the parchmentfilm length is 30cm, then stick the parchment on the rotating cylinder. Move the weight wheel to the starting point cylinder left and set the needed time from 5hours to 20 hours which it go over the whole distance the length of cylinder .If the ink don’t dry completely, then the weight wheel would leave a mark on the parchment blank space, till the test is finish. Obtain the test results by counting the ink traces on the parchment and rotating cylinder working speed.

Solvent Rub Resistance Tester

Solvent Rub Resistance Tester is designed according to ASTM D 4752 and NCCA11-18 Test Method for Measuring MEK Resistance of Ethyl Silicate (Inorganic) Zinc-Rich Primers by Solvent Rub.The Solvent Rub Test is usually performed using methyl ethyl ketone (MEK) as the solvent. The MEK resistance or degree of cure applies to paint topcoats and primers.

ASTM D4752 involves rubbing the surface of a baked film with cheesecloth soaked with MEK until failure or breakthrough of the film occurs. The type of cheesecloth, the stroke distance, the stroke rate, and approximate applied pressure of the rub are specified. The rubs are counted as a double rub (one rub forward and one rub backward constitutes a double rub).

The test is used widely in the paint industry because it provides a quick relative estimation of degree of cure without having to wait for long-term exposure results. It has been reported that the tests of two-component zinc-rich primers has shown good correlation with the cure of the primer as determined by diffuse reflectance infrared spectroscopy.

Features:

• Wide voltage range design (110-220V;50/60Hz), good compatibility
• Adjustable variable speed-5~95 c.p.m
• Micro-computer control, LCD displays data and set parameters.
• Parameters set freely and permanently storage.
• Glass work platform is easy to clean
