一,T-4涂4粘度計用途:
T -4型粘度杯是根據(jù)GB/T1723-93設(shè)計制造的。
T-4型粘度杯,屬于實驗室和車間、控制、試驗用儀器。所測定的粘度為條件粘度。即:一定量的試樣,在一定的溫度下,在所規(guī)定的直徑的孔中流出的時間.
本儀器有三種不同材質(zhì)的杯體,即塑料、鋁、銅,用戶根據(jù)實際情況自行選擇。
First, use:
The QND-4 viscosity cup is designed and manufactured according to GB/T1723-93.
QND-4 type viscosity cup belongs to laboratory and workshop, control and test instruments. The viscosity measured was the conditional viscosity. That is: a certain amount of sample, at a certain temperature, in the hole of the specified diameter.
The instrument has three different materials, namely plastic, aluminum and copper. The user chooses according to the actual situation.

三,T-4粘度計使用方法:
試驗前,將粘度杯內(nèi)部用紗布或脫脂棉蘸樣品本身所使用的溶劑擦試干凈。特別是流出口部分,要對光觀察,如果不干凈,應(yīng)繼續(xù)擦拭,直到干凈為止。
使樣品溫度保持在25℃±1℃內(nèi)。(或按產(chǎn)品標(biāo)準(zhǔn)規(guī)定的溫度)用試棒將樣品攪拌均勻,并靜止兩分鐘以上,試樣中不得有氣泡產(chǎn)生。
將擦試干凈并配好的粘度杯,放在支架上,調(diào)整支架水平螺釘,使粘度杯處于水平位置。
在粘度杯漏咀下面位置150ML搪瓷杯,用手指堵住流出口咀后,將被除數(shù)樣倒?jié)M粘度杯中。用試棒將多余之試樣割掉在年度杯邊緣之凹槽中,(注意:止時試樣中不應(yīng)有氣泡產(chǎn)生)然后移開手指,同時開動秒表,當(dāng)試樣流出中段并出現(xiàn)一滴時,停止秒表,此時秒表所指示的時間即為該產(chǎn)品的全部流出時間,也就是該產(chǎn)品的條件粘度值。
同一試樣的條件粘度值,應(yīng)作三遍后,求其算術(shù)平均值,但再吃測定值之差,不應(yīng)大于平均值3%。
粘度計使用完畢后,要注意將粘度計擦拭干凈放置保存。
Third, the method of use:
Before the test, wipe the inside of the viscosity cup with the solvent used for the gauze or the cotton wool sample itself. Especially for the outlet part, observe the light. If it is not clean, continue to wipe until it is clean.
The sample temperature was maintained at 25 °C ± 1 °C. (Or according to the temperature specified in the product standard) Stir the sample evenly with the test bar and stand still for more than two minutes. No air bubbles should be generated in the sample.
Place the cleaned and prepared viscosity cup on the bracket and adjust the bracket horizontal screw so that the viscosity cup is in a horizontal position.
Place 150ML enamel cup below the viscosity cup leaking nozzle, and block the outlet nozzle with your fingers, then fill the viscous cup with the divisor. Use the test stick to cut the excess sample into the groove at the edge of the annual cup. (Note: there should be no air bubbles in the sample when it stops.) Then remove the finger and start the stopwatch. When the sample flows out of the middle section and appears When a drop is made, the stopwatch is stopped, and the time indicated by the stopwatch is the total outflow time of the product, which is the conditional viscosity value of the product.
The conditional viscosity value of the same sample should be made three times, and the arithmetic mean value should be obtained, but the difference between the measured values should not be greater than the average value of 3%.
After using the viscometer, be sure to wipe the viscometer and store it.
