美國(guó)Cannon凱能蔡特福克斯玻璃粘度計(jì)簡(jiǎn)介:
The Zeitfuchs Transparent Viscometer measures kinematic viscosity of transparent Newtonian liquids according to ASTM D445 and ISO 3104. Filling, measurement and cleaning do not require removal from the constant temperature bath. Minimum sample volume is 15 mL. Minimum bath depth is 292 mm (11.5 in). Both calibrated and uncalibrated viscometers are available and provided with permanently attached round or rectangular metal holders. Calibrated viscometers also include a certificate of calibration and instruction sheet.

美國(guó)Cannon凱能蔡特??怂拐扯扔?jì)方法介紹:
美國(guó)Cannon玻璃毛細(xì)粘度管測(cè)試方法:ASTM D445, ASTM D446, ASTM D2170方法,透明和不透明液體運(yùn)動(dòng)粘度測(cè)定法 (包括計(jì)算動(dòng)力粘度),玻璃毛細(xì)管運(yùn)動(dòng)粘度計(jì)的規(guī)格及使用說(shuō)明,瀝青運(yùn)動(dòng)粘度的試驗(yàn)方法
原理:本法用以測(cè)定透明與不透明產(chǎn)品的粘度,它是在已知的溫度下,利用液體本身的重力流動(dòng)性(gravity-flow)來(lái)測(cè)定一定體積的液體通過(guò)經(jīng)校正后的毛細(xì)玻璃管粘度計(jì)所需的時(shí)間。根據(jù)所測(cè)出的動(dòng)力粘度可計(jì)算出公制粘度或粘度(dynamic viscosity)。
方法概要:取一定體積的液體在嚴(yán)格的溫度與固定的液面高度的控制下,使其流經(jīng)毛細(xì)管粘度計(jì)而計(jì)算其流經(jīng)時(shí)間。根據(jù)流經(jīng)時(shí)間與粘度計(jì)的校正常數(shù)的乘積即可得動(dòng)力粘度。
所需儀器:
1. 粘度計(jì): 校正過(guò)后的玻璃毛細(xì)管,其所測(cè)得的粘度能符合于所要求的復(fù)驗(yàn)準(zhǔn)確度再試準(zhǔn)確度。
2. 粘度計(jì)支架: 能將粘度計(jì)在恒溫槽中架持穩(wěn)固,且能使其垂直豎立。
3. 粘度計(jì)調(diào)溫槽: 內(nèi)盛裝透明液體,能使樣品于粘度計(jì)內(nèi)較液面低20mm以下,或高于槽底20mm以上,能保持槽內(nèi)溫度的變動(dòng)于15至100℃間低于±0.02℃的變化,在此溫度范圍以外,亦不超過(guò)±0.05℃的溫度變化。
4. 測(cè)溫器: 檢驗(yàn)動(dòng)力粘度計(jì)的溫度計(jì)內(nèi)盛有適當(dāng)?shù)囊后w,使之能符合溫度范圍,溫度計(jì)使用前均需校正,校正后準(zhǔn)確度在±0.02℃,若其它測(cè)溫器有上述的精確度時(shí)亦可采用。
5. 定時(shí)器: 秒表或彈簧裝置的定時(shí)器均可使用,但其刻度至少在0.1秒,其測(cè)定200秒至900秒的誤差在±0.07%以內(nèi)。
