Descriere

Tester digital automat de aderență BGD 500S

Pentru a funcționa satisfăcător, acoperirile trebuie să adere la substraturile pe care sunt aplicate. There are three different adhesion test procedures to assess the resistance of paints to separate from the substrate. The cross cut test, also described as cross-hatch, uses a blade to cut through the coating to the substrate. At least two cuts are made that intersect at 90 degrees to get a right angle lattice pattern. The cross-cut area is observed for any adhesion failure. The second method to test the coating adhesion is using a stylus or loop that an increasing amount of weight is applied until the coating is removed from the substrate. The third method called pull-off adhesion, measures the amount of tensile stress to pull the coating off the substrate. A dolly is glued to the coating surface, after the glue is cured, a testing apparatus is attached to the loading fixture and aligned to apply tension perpendicular to the test surface. Forța aplicată este crescută treptat și monitorizată până când se desprinde un dop de material de acoperire, sau se atinge o valoare specificată.

BGD 500/S automatical digital pull-off adhesion tester is a portable, instrument acţionat manual care este utilizat pentru a măsura forţa necesară pentru a trage un diametru specificat de acoperire de testare departe de substrat folosind presiunea hidraulică. Presiunea este afișată pe un LCD digital și reprezintă puterea de aderență a stratului de acoperire la substrat.

Evaluează aderența (pull-off strength) a unei acoperiri prin determinarea celei mai mari forțe de tracțiune pe care o poate suporta înainte de desprindere. Puncte de rupere, demonstrat prin suprafete fracturate, apar de-a lungul celui mai slab plan din cadrul sistemului format din dolly, adeziv, straturile de acoperire și substratul.

Characters

CONVENIENT

◆ Portable design, can be used anywhere.

◆ Built-in rechargeable lithium battery, no need any external power source.

◆ Selectable directlyfour different sizes dolly fordifferent resolution and testing range

◆ Get the testing results from LCD directly.

◆ Includes all tools needed for testing

AUTOMATICAL

◆ Originated in China, it can test automatically adhesion between coating and substrate by pull-off way and get good repeatable test results.

◆ Electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure. Greatly reduces user effort and the risk of influencing the pulling process.

◆ Internal memory stores maximum pull-off pressure, rate of pull, test time, dolly size.

◆ Pull rate is controlled by PID closed-loop, stable and adjustable.

◆ Can set a constant pull force to judge if the coating could be separated from substrate under a certain force.

◆ 5.0 inch big touch screen, display pull-off force curve, operator can see clearly how it change throughout the test.

PRECISE

◆ Each PsiaTester’s pressure system is calibrated to within 1% accuracy by NIST traceable load cells

◆ High-precise professional sensor ensures 0.01MPa resolution

◆ Self-aligning dollies ensure to get a reliable testing results for smooth or uneven surfaces.

◆ Come with calibration certificate

INTELLIGENT

◆ Store all test results （includes Max. pull-off power,pull-off rate, dolly size and time） automatically

◆ Two units （MPa and psi）for selection and can be converted automatically.

◆ USB interface as standard, no need any software, PsiaTesteris also a U disk, when connecting the computer, operator can read all data directly which is recorded during testing.

◆ Showing pull-off rate allows users monitor and adjust pull speed according to different test requirements.

DURABLE

◆ Waterproof, dustproof and shockproof design meets any harshest operating environment

◆ Strong plastic carrying case

◆ Two year warranty
