顯微測厚儀產(chǎn)品簡介本款顯微測厚儀系統(tǒng)依據(jù)ASTM D 5796制造，是金屬卷材上單層和多層涂料的指定測厚系統(tǒng)，本系統(tǒng)通過自帶的精密打孔裝置在樣品上鉆取微孔，顯微光學(xué)系統(tǒng)將微孔放大至400倍通過軟件一次性分別精確測量每個涂層的厚度，完全不受涂層化學(xué)性質(zhì)的影響，是目前所有測厚系統(tǒng)中*精確的多層測厚系統(tǒng)?？梢跃_、便捷的量測干膜厚度。本款顯微測厚儀產(chǎn)品特點(diǎn)

◆Can measure the thickness of each coating layer and whole coating layers at one time

各個涂層厚度一次性獲取

◆Can save and print data of each coating layer

各涂層數(shù)據(jù)通過電腦保存或者打印機(jī)輸出

◆Accurate measurement results based on 4 times， 8 times repeatable measuring

通過4次或者8次的定向測量，從而達(dá)到****的重復(fù)性

◆No coating material limitation

不受涂層、鍍層材質(zhì)和工藝的影響

◆No need to calibrate

無需校準(zhǔn)

◆No operator’s error

操作簡便直接，成功避免誤操作

◆Fast and accurate layer distinction among each coating layer

通過隨機(jī)量測軟件清晰便捷的界定各涂層

◆Easy to upgrade

容易升級

◆Wide application scope of Optical System such as length measurement， surface defect， paint film fault， etc.

光學(xué)系統(tǒng)還可以同時用于涂鍍層表面缺陷的檢視

◆Low maintenance

結(jié)構(gòu)簡潔精密，幾乎無需維護(hù)

顯微測厚儀測試原理（系統(tǒng)如何實(shí)現(xiàn)高精度的測量）◆Crater on the coating surface using a precise borer bit.

精密的打孔裝置在樣品表面一次性形成一個深度達(dá)到基材的圓潤的微孔

◆A shallow hole generated by the borer bit reveals each different coating layer from the substrate to the top coating.， Through a video microscope and high -resolution monitor， magnified bored-hole can be displayed and examined; The magnified crater displays each coating layer from the substrate to the finish coating layer.

如圖一所示，通過微孔展示的經(jīng)光學(xué)顯微系統(tǒng)和軟件處理的從基材到里層和表層的層間結(jié)構(gòu)

◆The image on the screen can be magnified 400 times.

顯微光學(xué)系統(tǒng)可以將微孔高保真放大至400倍

◆The thickness measurement of the coating layer is made by lining the crosslines (4 crosslines， 8 crosslines) from the beginning point to the ending point and measuring the distance between the 2 points with digital micrometer.

各涂鍍層的厚度通過在4個座標(biāo)方向或者8個座標(biāo)方向上的數(shù)字測距來精確得到

◆The actual thickness of the coating layer measured can be obtained by dividing the measured distance by 10. (Feature 1)

如圖二所示，a和b分別表示了兩個涂層的厚度
