　　涂層打磨性試驗機是檢測儀器，用于測定建筑物內墻、頂棚等室內膩子的打磨性。該儀器結構合理可靠，操作簡單，自動計數，整機重復性好。

　　Coating abrasiveness testing machine is a testing instrument for measuring the abrasiveness of indoor putty such as interior walls and ceilings of buildings.The instrument has a reasonable and reliable structure,simple operation,automatic counting and good repeatability.

　　涂層打磨性試驗機根據JC/T3049-1998（建筑室內用膩子）標準中對打磨性實驗的要求設計制造的。

　　The coating sanding tester is designed and manufactured according to the requirements of the sanding test in the standard of JC/T3049-1998(putty for building interior).

　　涂層打磨性試驗機工作原理：將貼有砂紙的試塊在試板的涂層表面作直線往復運動。打磨至產品規定的次數后，觀察砂紙上沾有的膩子粉末的面積，以判斷涂層的打磨性。

　　The working principle of the coating sanding tester:the test block with sandpaper is made to reciprocate linearly on the coating surface of the test plate.After grinding to the specified number of times,observe the area of putty powder on the sandpaper to determine the abrasiveness of the coating.

　　涂層打磨性試驗機技術參數：

　　★打磨塊運動頻率：（37±2）次min

　　★打磨塊運動距離：300mm(兩端）

　　★打磨塊和夾具重：（450±5）g

　　★打磨塊尺寸：90mm*38mm

　　★設定計數范圍：0---9999

　　★電源：Ac220V，50Hz,3A

　　★外形尺寸：（620*490*460）mm

　　Technical parameters of coating sanding tester:

　　★Moving frequency of grinding block:(37±2)times min

　　★Moving distance of grinding block:300mm(both ends)

　　★Weight of grinding block and fixture:(450±5)g

　　★Grinding block size:90mm*38mm

　　★Set counting range:0---9999

　　★Power:Ac220V,50Hz,3A

　　★Dimensions:(620*490*460)mm

　　涂層打磨性試驗機操作規程：

　　★將試板水平固定在打磨機的試驗臺板上，涂層面朝上，在工作中試板不得串動。

　　★將橫臂上的元寶螺母旋下，將橫臂及打磨塊部件卸下，轉動打磨塊部件上的轉軸和螺母，將（120）回（0號）干砂磨紙（190*90用戶自備）貼于打磨塊上將橫臂部件重新裝回打磨性試驗機上，讓打磨塊置于試板的膩子涂層上，使打磨性部件在橫臂中上下活動自如，重量落在試板上。

　　★接通電源。按標準要求設定打磨次數，打開電源開關，按動置數開關，使計數顯示設定值。然后按動啟動電源，儀器將開始工作（若打開電源后，有數值顯示，請按復位開關）。

　　★計數顯示器開始自動計數，由設定值減至為零數時，儀器自動停止工作，實驗完畢。若想途中停機，按動暫停開關即停。

　　★按動復位開關，取出試板，觀察判斷實驗結果。

　　試驗結束后，小心取下橫臂及打磨塊部件，目測打磨砂紙上沾有的打磨粉末為砂紙面積的20%—80%為合格。

　　Coating sanding test machine operating procedures:

　　★Fix the test plate horizontally on the test bench of the sander with the coating side facing up.The test plate must not be moved in series during work.

　　★Unscrew the ingot nut on the cross arm,remove the cross arm and the grinding block part,turn the shaft and nut on the grinding block part,ａnd return(120)back to(No.0)dry sanding paper(190*90 user self Note:Put it on the grinding block and put the cross-arm part back on the grinding tester.Put the grinding block on the putty coating of the test plate,so that the abrasive part can move up and down freely in the cross arm,ａnd the weight completely falls on the test plate.on.

　　★Turn on the power.Set the number of polishing times according to standard requirements,turn on the power switch,ａnd press the setting switch to make the count display the set value.Then press to turn on the power,ａnd the instrument will start to work(if the numerical value is displayed after turning on the power,press the reset switch).

　　★The counting display starts counting automatically.When the set value is reduced to zero,the instrument automatically stops working and the experiment is complete.If you want to stop on the way,press the pause switch to stop.

　　★Press the reset switch,remove the test plate,ａnd observe and judge the experimental results.

　　After the test,carefully remove the cross arm and the sanding block components,ａnd visually observe that the sanding powder on the sanding paper is 20%to 80%of the area of the sandpaper.

　　涂層打磨性試驗機結構：

　　該儀器主要由打磨塊及夾具、滑動架、實驗臺板、電動機、電源開關、計數器等部件構成。

　　Coating grinding tester structure:

　　The instrument is mainly composed of a grinding block and a fixture,a sliding frame,an experimental table,a motor,a power switch,a counter and other components.

　　涂層打磨性試驗機注意事項：

　　1.儀器在工作時，計數器不得隨意設定。

　　2.儀器的放置應以水平為準后方可作試驗。

　　3.每次試驗需要置換砂紙。

　　4.一起使用較長時間后，應將儀器拆開，向變速箱內注入20#機油。再兩導杠的泊孔中亦應注入機油，但不應過量

　　Precautions for coating abrasive tester:

　　1.The counter must not be set arbitrarily while the instrument is working.

　　2.The instrument should be placed on the level before testing.

　　3.Replace sandpaper for each test.

　　4.After using together for a long time,the instrument should be disassembled and 20#engine oil should be injected into the gearbox.Oil should also be injected into the mooring holes of the two guide bars,but should not be excessive.
