騰達(dá)試驗(yàn)儀器廠：
一、概述：
試驗(yàn)裝置由錘頭、錘柄及底座三個(gè)構(gòu)件組成。符合GB/T2694-2010、YDT757等標(biāo)準(zhǔn)的落錘試驗(yàn)方法，適用于熱浸鍍鋅層附著力試驗(yàn)，是利用錘頭自由跌落擊打試樣來測(cè)試鍍鋅層是否合標(biāo)準(zhǔn)。本產(chǎn)品適用于鐵塔類似生產(chǎn)廠家和質(zhì)檢部門進(jìn)行產(chǎn)品質(zhì)量檢測(cè)和控制。
Overview of Hot Dip Galvanized Coating Adhesion Tester
The test device consists of a hammer head,a hammer handle and a base.The drop weight test methods that comply with GB/T2694-2010,YDT757 and other standards are applicable to the hot-dip galvanized coating adhesion test.The hammer head is used to freely hit the sample to test whether the galvanized layer meets the standard.This product is suitable for product quality inspection and control of similar tower manufacturers and quality inspection departments.
二、特點(diǎn)：
錘頭表面應(yīng)光滑、平整、無毛刺。錘頭與錘柄結(jié)合應(yīng)牢固；底座與錘柄之間穎活動(dòng)靈活。外形尺寸錘頭、錘柄及底座公稱尺寸及允許偏差見表所示
Features of Hot Dip Galvanized Coating Adhesion Tester:
The surface of the hammer head should be smooth,flat and free of burrs.The combination of the hammer head and the hammer handle should be firm;the gliding movement between the base and the hammer handle should be flexible.The dimensions and allowable deviations of hammer head,hammer handle and base are shown in the table.
三、技術(shù)參數(shù)：
1、錘頭質(zhì)量：210g±1g
2、錘頭心線至底座面垂直高度：300mm±1mm
3、錘柄材料：橡木
Technical parameters of hot dip galvanized layer adhesion tester
1.Mass of hammer head:210g±1g
2.Vertical height from hammer head centerline to base surface:300mm±1mm
3.Hammer handle material:Oak
四、使用方法：
試件置于水平，調(diào)整試樣，使打擊點(diǎn)距試樣邊、角、端部不小于10mm，錘頭面向臺(tái)架心，錘柄與底座平面垂直后自由落下，以4mm的間隔平行打擊5點(diǎn)。檢查鍍鋅層表面狀態(tài)是否符合標(biāo)準(zhǔn)要求，打擊處不得重復(fù)打擊.
How to use the hot-dip galvanized coating adhesion tester:
The test piece is placed on the level,ａnd the specimen is adjusted so that the impact point is not less than 10mm from the edge,corner and end of the specimen.The hammer head faces the center of the stand.point.Check whether the surface condition of the galvanized layer meets the requirements of the standard.Do not repeat the strike at the strike.
