Sutherland  2000 油墨磨耗試驗機-行動條碼QR Code

SUTHERLAND 印刷耐磨性試驗機由馬達驅動,使加載以特定重量的測試印刷樣本在一個標準面上來回擦拭,以檢驗其耐磨性。

SUTHERLAND油墨耐磨試驗機幾十年來一直被作為該行業的一個工業標準,近期設計者又對該儀器進行了一些卓有成效的改進,更提高了它的性能和可靠性。如今它成為美國ASTM標準協會的推薦使用產品(請參考ASTM D-5264 ? 92, Standard Practice for Abrasion Resistance of Printed Materials by the Sutherland Ink Rub Tester)。該標準提供了SUTHERLAND印刷耐磨試驗機的正確程序,這極大地提高了它的知名度和應用範圍,使它在未來市場中處於更為有利的地位。在保留原有優點的同時,這些改進也使該儀器的運行成本更為經濟,實驗結果更符合工業標準。

SUTHERLAND印刷耐磨試驗機不僅適合於測試印刷品的耐擦性及耐磨性,同時在其它行業(如清潔劑,蠟,地板瓷磚,薄膜等等)也擁有數量眾多的用戶,它的測試結果重現性非常好。

若選購加熱組件,可在95...260℃不同條件下進行高溫磨擦試驗,再現性極佳!

For Abrasion Resistance Of Printed Materials By Sutherland Rub Tester

 

Only Tester Used In Establishing ASTM Designation D 5264 Standard Test Method

The tester is a motor driven instrument for moving a weighted test strip over a printed specimen through an arc. The Sutherland Rub Tester has been redesigned to improve its operation. James River's corporate research and development laboratories did extensive testing of the Sutherland Rub Tester. The result of this work is an affordable abrasion testing instrument that retains all the features that made it an industry standard plus improvements that ensure it will remain the industry standard.

The stroke of the tester has been shortened which increases the precision and more closely simulates abrasion damage found in the field. James River research and other published work in the print abrasion testing arena have shown that quick strokes simulate some types of rub damage (most notably shipping damage).

 

Illustrated is the Sutherland Rub Tester showing two-pound and four-pound weights to which test specimens are attached and the scoring device.

The upper receptacle of the timer is for remote timer control. The lower receptacle is the same voltage as the instrument. 110 volts single phase is standard. 220 volts optional at extra cost.

The Sutherland®2000™motor now has four speeds; the first speed (21 cycles per minute) is half the speed as the older models, which will make the "wet" tests, and tests using under 5 strokes easier to perform. The second speed (42 cycles per minute) are the same as the older models, while the fourth speed (106 cycles per minute) is faster. These new improvements will allow the customer the ability to customize the testing procedure more to their individual product, yet maintaining the ability of duplicating a procedure used by someone with an older model unit. The higher speeds will reduce the long test times needed for certain types of substrates (plastics, UV varnished, printed films, etc.).

The Sutherland®2000™ incorporates a digital counter with a fiber optic sensor to ensure the accuracy of the number of rubs for a given test. Simply enter the number of rubs desired and the instrument will stop automatically at exactly the correct number of strokes.

 

A single mounting pad for the test strip is now cut to fit the weight. It was found that precision of the test is increased by using a 2 inch (5 cm) by 4 inch (10 cm) pad on the bottom of the weight . Two pound and four pound weights and scoring fixture are included.

A supply of 80 x 80 count bleached muslin cloth (cloth not included) has been found useful in testing wet smear, wet rub, and wet bleed. The Sutherland Rub Tester is designed to evaluate the scuffing or rubbing resistance of the printed or coated surface of paper, paperboard, film, etc. The test results are reproducible.

The following tests may be made with the instrument:

  • Dry Rub
  • Wet Rub
  • Wet Bleed or Transfer
  • Wet Smear
  • Functional Rub

 

Test Specimen

 

The test requires two pieces of stock, the printed test specimen and a test receptor, which is usually unprinted. Cut a test specimen, approximately six by three inches, representing average ink lay and coverage. When the printed area permits, the six inch direction should be cut across the grain of the sheet, but must not cross pressed or cut scores.

Prepare test strips of unprinted material from the same shipment of stock used in printing the test samples. Cleanly cut 2 x 7 inch strips for the four-pound weight are prepared by placing a strip face down against the end pin of the scoring device and scoring the strip at the white dot positions to facilitate bending the strip to conform to the test block.

To prepare samples for the two-pound weight, 2 x 5-1/4 inch strips are placed face down against the end pin of the scoring device and score at the red dot position to facilitate bending the strip to conform to the test weight.

Reference: "The Improved Sutherland Rub Tester" by Dr. Bruce Blom, Senior Research Fellow, Mead Central Research Laboratories, Chillicothe, OH

Because of the simplicity of the tester, it is currently being evaluated as a means for assessing the drying, degree of cure, and solvent resistance of inks as part of ASTM's subcommittee D-01.56 on printing ink activities.
