　　漆膜圆锥弯曲试验仪是检测仪器，适用于测定色漆、清漆的涂层（包括单层与复合涂层系统）在标准条件下，绕锥形轴弯曲时，抗开裂或从金属底板上剥离的性能，也可测定该涂层的延伸率。使用前务必仔细阅读说明书。并由**实验人员操作，以避免操作不当引起的伤害。如需了解更多资料请与我公司客服人员联系。

　　Film cone tester is a testing instrument,which is suitable for determining the coating of color paint and varnish(including single-layer and composite coating systems).Under standard conditions,it is resistant to cracking or cracking from the metal base plate when it is bent around a tapered axis.The peeling performance can also be measured by the elongation of the coating.Be sure to read the instructions carefully before use.It is operated by**experimental personnel to avoid injury caused by improper operation.For more information,please contact our customer service staff.

　　漆膜圆锥弯曲试验仪结构与工作原理：

　　该仪器为纯机械式，其结构主要由锥形轴1，拉杆3，操纵杆6，夹紧试板2等装置组成。

　　其原理为：将试板插入拉杆与锥形轴之间，并用夹板夹紧手握操纵杆，由前向后翻轴（使试板绕锥形轴变曲），根据试板上涂层的裂痕位置来测定其剥离性能。

　　Structure and working principle of paint film cone bending tester:

　　The instrument is purely mechanical,and its structure is mainly composed of tapered shaft 1,draw rod 3,joystick 6,clamping test plate 2 and other devices.

　　The principle is:insert the test plate between the pull rod and the tapered shaft,and clamp the hand lever with the splint,and turn the shaft from front to back(to make the test plate bend around the tapered shaft).The crack position was used to determine its peeling performance.

　　漆膜圆锥弯曲试验仪操作与使用方法：

　　★将制备好的试板的短边20mm处，平行的裁去（裁去20mm*100mm以免试板边缘影响测试结果）。

　　★将操纵杆6放在V形支承5上，将试板涂膜面朝着拉杆3插入，使其一个短边（裁去20*100处）与轴的小端相接触，然后转动旋钮4将试板夹住，然后均匀平稳地转动操纵杆使试板弯曲，使其在2—3S时间绕轴180°。记录与轴小端相距A远的试板开裂处（指涂膜开裂），并做标记，然后取下试板。

　　Operation and use of paint film cone bending tester:

　　★Cut off the short side of the prepared test plate 20mm in parallel(cut 20mm*100mm to avoid the test plate edge from affecting the test result).

　　★Place the joystick 6 on the V-shaped support 5 and insert the test plate coating film side toward the pull rod 3 so that one short side(cut 20*100)is in contact with the small end of the shaft,and then turn the knob 4 Clamp the test plate,and then turn the joystick evenly and smoothly to bend the test plate,making it 180°around the axis in 2-3S time.Record the crack on the test plate(referred to the cracking of the coating film)far from the small end of the shaft by A,mark it,and then remove the test plate.

　　漆膜圆锥弯曲试验仪维护：

　　★使用一段时间后，转动部位注少许机油，以保证其转动灵活。

　　★不使用时应用仪器罩遮盖，用以防尘。

　　Paint film cone bending tester maintenance

　　★After using for a period of time,fill the rotating part with a little oil to ensure its flexible rotation.

　　★Cover the instrument cover when not in use to prevent dust.
