Product Details

Ⅰ. Introduction:

HY-Ⅳ (Wood)Scratch Tester produced by our company is accordance with specification of National Standard GB/T 15102-94《Surface decorated wood-based pands with paper impregnated thermosetting resins》and GB/T 15657-1999《Test Method of physical and chemical performance for Hard board and finished hard board》. This tester is applicable to determine the scratch resistance of hard board and finished hard board. The machine adopts gear reducer with larger velocity ration and larger output torque so as to ensure revolution of rotary turntable constant under the different measuring load, making testing result high accurate. All components of the Scratch Tester produced by our company are installed in the wood box with handle, the instrument featuring compact structure, smaller overall dimensions, convenient carrying, etc. 



 

Ⅱ. Main Structure:

(Wood)Scratch Tester utilizes lever rule, when the upper side of scale locates at leveling position, moving the weight on the scale to the different graduation, making the force of the top of diamond scratching needle on the surface of tested plate identical with graduation. The scale shaft adopts ball bearing supporting, rotating flexibly, reducing friction moment, and making pressure on the top of diamond scratching needle good repeatability. That ensures testing result good repeatability.

Ⅳ. Operating Procedure:

1.Preparing work before test (see figure 1)
(1)Put this instrument on the stable, flat test desk, operator faces instrument, then opening packing box of instrument.
(2)Loosen the fixed screw of sliding rod: taking out sliding rod with scale (with division) and scale support beam (without division) from the accessory box, separately insert into left and right hole of scale support. The flat end of sliding rod with scale (scale beam) is inserted into hole; when the whole coil engraving line of scale beam end is just showing from the backside of scale support, tightening fixed screw of beam, fixing the scale beam, scale support rod can freely slide in the hole.
(3)Taking the scale from the scale support, with division side facing operator, putting bearing hole in the middle of scale facing scale beam and inserting it into a hole.
(4)Lifting the right end of scale, pulling out scale support rod, putting down scale, and putting the scale on the scale support rod. (see front cover figure)
(5)Taking out diamond scratching needle, placing the beam in position by lining up the bearing with the projecting shaft, fixing it by right fastening screw.

(6)Insert the plug in the socket, which is on the wall, and switch-on.
2.Operation:
(1)Process the testing board to the standard stipulated dimension (Thickness is not over 10mm), drill a 7mm hole on the central position.
(2)Loosen fixed nut of test specimen, take down clamping plate of test specimen, put the processed testing board on the rotating turntable of test specimen. The central screw strikes central hole, put the clamping plate of test specimen on tighten fixed nut of test specimen.
(3)Push in the scale support rod, put down scale, make the top of diamond scratching needle on the testing board surface.
(4)Loosen scale support screw.
(5)Rotate scale support screw, adjust the scale to the leveling position. (Observing leveler above the weight, making the air bubble between two engraved line, the scale locates at leveling position.
(6)Tighten scale support screw.
(7)Loosen weight screw, moving the weight to the needed loading division (right edge of weight aims at division) tighten weight screw.
(8)Press starting button, the rotating disc of test specimen is starting to rotate. After rotating one circle, stop it , take out test specimen and observe the scratch on the surface of test specimen.
(9)After finished the all test, dismount the component of the machine, put it on the original position of packaging wood box, cover it so as to protect the cleanliness of this machine.
