The paper tape abrasion tester must be used for the abrasion test of mobile phone shell

1、 R.c.a paper tape friction tester Product Name: RCA wear resistance tester detailed introduction: product model brief introduction: This RCA machine is completely adjusted and calibrated according to the technical standards of Norman tool company in the United States, and the paper tape friction tester has reached the consistent technical parameters through comparative test This machine is suitable for wear resistance test of mobile p.d.a laptop and various surface coating products, After rubbing the uncoated paper or tape with the sample, the abrasion effect can be judged under a certain number of rotations This machine's special Description: 1 Rubbing the uncoated paper or tape with the sample to check the abrasion effect of the coating layer under a certain number of rotations 2 The standard test load is 275g (the weight reduction weight is not added to the lever), Two weight reducing weights are attached, and the test load can be reduced to 175g or 55g, so as to apply to different test conditions or softer materials 3 Two sample fixing methods can be selected 4 A lamp type magnifying glass is attached to check 5 Counter: rotary counter, Led counter (settable times) standard accessories: one set of tools, one magnifying glass, one test weight reduced to 55g, one test weight reduced to 175g, one universal holder, three O-ring accessories: paper roll x 1 roll origin: Taiwan II, RCA 7-ibb: special paper tape for friction testing machine application: mobile phone, plastic, chemical coating, electroplating, etc! Manufacturer: American normal unit: box (40 rolls) test precautions: 1) the storage conditions of paper tape and the temperature and humidity of the site where the test is conducted should be controlled within a certain range (it is recommended to store the moisture-proof box) Temperature range: 23 ± 2 ℃, humidity range: 50 ± 10% 2) is the cross section of the O-ring of the testing instrument circular, flat, hard, cracked, or used for more than 6 months? In case of the following 4 conditions, please replace the O-ring and test it 3) the roller where the O-ring is located needs to be cleaned every day If it is not cleaned in time, the round shaft may not rotate freely 4) RCA paper tape can only be used once, because the abrasiveness of the paper tape will change after being used once In addition to the RCA produced by normantool in the United States At home and abroad, there are many manufacturers producing nominal RCA paper We hereby solemnly remind users that the test results of using these papers cannot be guaranteed by normantool company of the United States, and Zui's main problem is that serious deviation may occur and Zui will eventually cause economic loss to protect the interests of users This paper introduces the method to judge whether RCA paper is produced by normantool company as follows: use the original correction plate of Norman tool Inc to test This correction plate has been calibrated on the master machine of Norman tool, and has a certificate indicating the number of laps required for the paper tape to wear through the correction plate This item will have been tested on Norman tool's "master tester" and includes all test results You must provide your tester serial number to receive this kit Place the calibration plate at the position of the test sample, and measure the number of turns required for the paper tape to wear through the coating on the calibration plate to see if it is consistent with the number of turns on the certificate The test error is allowed to be within 5% - 10% If the test result of paper tape exceeds RCA 7-ibb on the certificate: special paper tape for friction tester: mobile phone, plastic, chemical coating, electroplating, etc! It belongs to the special test paper tape for rca-7-ibb wear resistance tester Manufacturer: American norm specification parameters: 1 11 / 16 "wide band for general printing test; 2.41 pounds, 1.4 cubic feet; 3 40 rolls in each case; 4 1050 rolls in length; 1800 laps in each roll 1) the paper tape shall be stored in a dry and cold place 2) The temperature and humidity of the experimental site should be controlled within a certain range Temperature range: 23 ± 2 ℃, please store in dry and cold place Humidity range: 50 ± 10% (humidity 45% ~ 50%) 3) Is the cross section of the O-ring of the testing instrument circular, flat, hard, cracked, or used for more than 6 months? If the latter four conditions occur, replace the O-ring and test 4) Make sure that the roller where the O-ring is located needs to be cleaned every day If it is not cleaned in time, the round shaft may not rotate freely 5) RCA paper tape can only be used once, because the abrasiveness of paper tape will change after it is used once In addition to the RCA paper produced by normantool in the United States, there are many manufacturers producing nominal RCA paper in the domestic market We hereby solemnly remind users that the test results of using these papers can not be guaranteed by normantool company of the United States, and the main thing of Zui is that serious deviation may occur and Zui will eventually cause economic loss In order to protect the interests of users, this paper introduces the method to judge whether RCA paper is produced by normantool company as follows: the method is as follows: use the original correction plate of Norman tool Inc to test This correction plate has been calibrated on the master machine of Norman tool, and has a certificate indicating the number of laps required for the paper tape to wear through the correction plate This item will have been tested on Norman tool's "master tester" and includes all test results You must provide your tester serial number to receive this kit Place the calibration plate at the position of the test sample, and measure the number of turns required for the paper tape to wear through the coating on the calibration plate to see if it is consistent with the number of turns on the certificate The test error is allowed to be within 5% - 10% If the test result of the paper tape exceeds 10% of the mark on the certificate, it can be judged as RCA paper not produced by normantool RCA 7-ibb: the O-ring ring ring of the friction tester belongs to the special purpose of rca-7-ibb wear tester Precautions: 1 Whether the cross section of the O-ring of the tester is circular, flat or hard 2 Or when there are cracks, or the use of a long time more than 6 months 3 If the above four conditions occur, please replace the O-ring and test 4 Make sure that the roller where the O-ring is located needs to be cleaned every day If it is not cleaned in time, the round shaft may not rotate freely.
