直線式干燥時(shí)間測(cè)定儀是檢測(cè)儀器，是測(cè)量漆膜干燥時(shí)間的一種新型儀器，它對(duì)涂在表面上的色漆、清漆等各種涂料由流體變成穩(wěn)定的薄膜，都能以描繪直線軌跡的形式、自動(dòng)連續(xù)展現(xiàn)干燥過(guò)程各個(gè)階段的狀態(tài)，能直觀的分析各階段所用時(shí)間。
The linear drying time tester is a testing instrument. It is a new type of instrument for measuring the drying time of paint films. It can change the paint on the surface, such as paints and varnishes, from fluid to a stable film. The form of the straight line trajectory, the state of each stage of the drying process is automatically and continuously displayed, and the time taken by each stage can be intuitively analyzed.
直線式干燥時(shí)間測(cè)定儀工作原理：
將制備好的漆膜試板放在試板托盤(pán)上，接通電源，電機(jī)通過(guò)絲杠帶動(dòng)劃針做勻速直線運(yùn)動(dòng)（六個(gè)托盤(pán)每?jī)蓚€(gè)為一種時(shí)間即6h、12h、24h，全程為305mm）。由于漆膜隨時(shí)間延長(zhǎng)而逐漸干燥，因而劃針在漆膜上的犁痕由寬變窄，由深變淺，以至A后劃不出痕跡，從而顯示出干燥情況的全過(guò)程。
Working principle of linear drying time measuring instrument:
Put the prepared paint film test plate on the test plate tray, turn on the power, and the motor drives the stylus through the screw to make a linear motion at a uniform speed. (Each two of the six trays is a time, that is, 6h, 12h, and 24h. The whole process is 305mm). As the paint film gradually dries over time, the plough marks on the paint film will be narrowed from width to depth, and shallower to deeper, so that no marks can be found after A, thus showing the whole process of drying.

直線式干燥時(shí)間測(cè)定儀使用說(shuō)明：
★ 依涂膜的干燥快慢，選擇適當(dāng)?shù)臅r(shí)間（6h、12h、24h）。
★將劃針抬起，將大提扭向上抬起，推滑動(dòng)座至左端，將如前所述制備好的試樣放在托盤(pán)上，放下劃針和大提扭。
★ 接通電源，按下電源開(kāi)關(guān)，指示燈亮，再按下相應(yīng)的分開(kāi)關(guān)，指示燈亮，劃針開(kāi)始做勻速直線運(yùn)動(dòng)，到終點(diǎn)自動(dòng)停止運(yùn)動(dòng)，而后將開(kāi)關(guān)關(guān)閉。
★取下試板之前，在啟始點(diǎn)做一記號(hào)，再分出各個(gè)干燥階段，而后取下試板與時(shí)間標(biāo)尺對(duì)照，便可判斷出整個(gè)干燥過(guò)程的各個(gè)階段所用的時(shí)間，亦可用計(jì)時(shí)表測(cè)量（注：計(jì)時(shí)表應(yīng)與劃針啟動(dòng)同步）。
★ 砝碼重5g，插在劃針上部，一般用于漆膜較厚或干燥后較硬的場(chǎng)合。
★ 試驗(yàn)后將玻璃試板上的涂料及劃針頭部的粘附物洗去，擦干以備下次使用。

Instructions for use of linear drying time tester:
★ Select the appropriate time (6h, 12h, 24h) according to how fast the coating film dries.
★ Raise the stylus, lift the large lifting knob up, push the slide to the left end, place the sample prepared as described above on the tray, and lower the stylus and large lifting knob.
★ Turn on the power, press the power switch, the indicator light is on, and then press the corresponding sub-switch, the indicator light is on, the stylus starts to make a linear motion at a uniform speed, it will automatically stop moving at the end point, and then turn off the switch.
★ Before removing the test plate, make a mark at the starting point, and then separate the drying stages, and then take off the test plate and compare it with the time scale to determine the time used in each stage of the drying process. (Note: the chronograph should be synchronized with the start of the hand).
★ The weight is 5g. It is inserted in the upper part of the stylus. It is generally used in the place where the paint film is thick or hard after drying.
★ After the test, the paint on the glass test board and the adhesion on the head of the stylus are washed away and dried for the next use.
