一、產品簡介

I. brief introduction

聚合物乳液用作涂料、粘合劑、化纖織物、皮革、紙張等表面的處理劑時，它的成膜性是重要的技術指標之一。研究者為了制造出更低成膜溫度的新產品來，不斷地改進其技術規範和配方。因此檢測出低成膜溫度(MFT)是此類涂料的重要指標，能夠方便的測出MFT的理想儀器。MFT型低成膜溫度測定儀是依據國家標準GB9267-2008而設計制造的，它是新一代漆膜測試儀，具有國內外傳統測試儀器的諸多優點，又融合了臺式、節能、超寬工作臺、測溫準確等優點於一體，成為同類儀器之佼佼者。本手冊中的所有圖片和產品規格參數僅供參考，實際產品可能會略有差異，恕不另行通知。

When polymer emulsion is used as coating, binder, chemical fiber, fabric, leather, paper and other surface treatment agent, its film forming property is one of the important technical indexes. The researchers continually improved their technical specifications and formulations in order to produce new products with lower film forming temperatures. Therefore, the detection of the minimum film forming temperature (MFT) is an important indicator of this kind of coating, and it can conveniently measure the ideal instrument of MFT. MFT minimum film-forming temperature measurement instrument is designed and manufactured according to the national standard GB9267-2008, it is a new generation of film tester has many advantages at home and abroad test instrument, and the integration of the desktop, energy saving, wide working platform, accurate temperature measurement method, as a leader in similar instruments. All the pictures and product specifications in this manual are for reference only, and the actual products may be slightly different without notice.

四、使用方法

Four, the use of methods

打開包裝箱，（包裝箱可以反復利用，請妥善保管，以便以後維修運輸之用）檢查一下有無破損短缺現象。核實後，將儀器安放在試驗室靠近上下水之處，先做一下清潔工作。然後查看電源輸入，進出水口接牢無誤。

Open the packing box (the packing box can be used again and again, please keep it for future maintenance and transportation). Check for any breakage. After verification, put the instrument in the laboratory, near the upper and lower parts of the water, do some cleaning work first. Then check the power input and make sure the inlet and outlet are secure.

使用前的準備工作：

Preparation prior to use:

★開機：

Boot:

將電源線接入電源插座（220 伏，50Hz 三孔插座，接地良好），接通冷卻水，依次接通總電源開關、加熱、巡檢、制冷開關，儀器面板立即顯示出相應動作（指示燈亮，數顯表顯示數字）。

The power line access power socket (220 V, 50Hz socket, must be well grounded), connected to the cooling water, turn on the power switch, heating, cooling, inspection switch, instrument panel immediately show the corresponding action (indicator lights, digital display digital).

★調試儀表：

By debugging instrument:

根據所測試漆膜條件不同，需設置不同測試條件。主要是制冷和加熱預置（設置方法見 LU-906M 智能調節器使用說明書），巡檢表在出廠前已調好，一般情況下不需調整。

Different test conditions need to be set according to different test conditions. Mainly refrigeration and heating preset (set method see LU-906M intelligent controller manual), the inspection table before the factory has been adjusted, in general, need not adjust.

★熱平衡：

By the heat balance:

時間約在 120 分鐘左右（視設定溫度而定，若發現巡檢表在時間內 1 ～ 13 各點顯示穩定或變化極小即為預熱完成）方可加入試樣。平衡時間取決於低溫度設定，溫度設定越低，平衡時間則越長。幹燥劑同時放入盒中，可以大限度避免水蒸氣以及冷端結冰。

Time is about 120 minutes (depending on the setting temperature, if the inspection table is found within a certain period of time, 1~13 points show stability or minimal change, that is, preheating is completed), you can join the sample. The balance time depends on the minimum temperature setting, and the lower the temperature setting, the longer the equilibrium time. The desiccant is also placed in a box to minimize water vapor and cold end ice.

五、樣品準備

Five sample preparation

取下玻璃罩用小勺或滴管將待測和已知乳液注入梯度板槽內，再用涂布器涂平，蓋好玻璃罩。（玻璃制品，請輕拿輕放）

Remove the glass cover, use a spoon or dropper to inject the tested and known emulsion into the gradient plate trough, then coat it with a coater and cover the glass cover. (glass, please handle with care.)

★樣品成膜：

The film samples:

大約經過 60 ～ 90 分鐘，梯度板上的涂層發生一係列的變化，乳膠漆用乳液水分蒸發後，聚合物分子相互作用，在適當溫度下形成連續薄膜，高於該乳液 MFT 的部分成膜透明，低於 MFT 的部分發生龜裂或產生白堊現象。這個明顯的分界線即為該乳液的低成膜溫度（MFT）確定成膜線後，根據其位置，用標尺的細分刻度計算出準確溫度。

After about 60 to 90 minutes, the coating plate on the gradient of a series of changes, the latex emulsion evaporation, interaction between polymer molecules, forming a continuous film at a suitable temperature is higher than that of the MFT part of the emulsion film is transparent, less than MFT part of the crack or produce chalk phenomenon. The obvious dividing line is the minimum film forming temperature (MFT) of the emulsion. After determining the film forming line, the accurate temperature is calculated by the scale of the ruler according to its position.

★關機：

* shutdown:

試驗完畢後，關閉電源、水源，做好各部位的清潔工作，為下一次試驗做好準備。

After the test, turn off the power, water, do a good job cleaning the parts, prepare for the next test.

★測試條件主要是制冷和加熱的設定。制冷主要影響低溫端工作，以第一點要求為準。加熱主要影響高溫端工作，以第十三點要求為準。盡量減小冷熱差，即節能，又可提高分辨率，

It is the main test conditions of heating and refrigerating set. The refrigeration mainly affects the low temperature end, and the first point is required. Heating mainly affects high temperature end work, whichever is required by thirteenth points. Minimize cold and heat difference, that is, energy saving, but also to improve the resolution,

★工作臺使用前後要清洗，長時間放置時涂些油脂或凡士林，以防銹蝕。

This table should be cleaned before and after use, place a long time when coated with grease or vaseline to prevent rust.

★涂布待測乳液時，至少要有一條已知材料，以作對照之用。

* to be measured when the emulsion coating, must have at least one known material for control purposes.

★涂布乳液時不要涂滿測試槽，只要涂在估計MFT 左右即可，既省工料又好清洗。

You don't have to emulsion coating painted test tank, as long as the painted around MFT can be estimated, both quantity and good cleaning.

★用衛生紙條放置在梯度板左右邊緣，以防涂布和清洗時弄臟工作臺。

I use note placed at the edge of the gradient in health, to prevent the coating and cleaning dirty work station.

★為了清洗方便，板表面可以覆蓋一層薄的鋁箔（如0.02mm 厚）, 用刷子將其刷平 , 可滴幾滴甘油使鋁箔和板面緊密結合。

In order to more convenient cleaning, the plate surface can be covered with a layer of thin aluminum foil (0.02mm thick), use the brush to brush the flat, a few drops of glycerin and combination of aluminum foil surface.
