LCR 7000 - Dynisco 毛細(xì)管流變儀 Capillary Rheometer產(chǎn)品描述

通用性

新款LCR7000系列毛細(xì)管流變儀的眾多新功能，可滿足每天24小時的車間運(yùn)行要求，同時盡可能維持zui高水平的準(zhǔn)確性、重復(fù)精度和靈敏性。LCR系列流變儀為通用型，易于使用，具備復(fù)雜的材料特性分析、數(shù)據(jù)分析和報告功能，并且可與標(biāo)準(zhǔn)稱重傳感器和安裝了壓力傳感器的機(jī)筒配合使用。

成熟的軟件

LAB KARS（“Kayeness的流變學(xué)軟件”）是市面上強(qiáng)大和易于使用的、以Windows™為運(yùn)行平臺的流變學(xué)軟件包。其易于使用的功能包括：Bagley和Rabinowitsch校正，加上冪次法則、卡羅流體模型、Modified Cross和多項(xiàng)式粘度模型。通過此軟件，用戶能夠合并剪應(yīng)力、剪切速率或熱穩(wěn)定性測試等多個數(shù)據(jù)文件。內(nèi)嵌的KARS SQC模塊可用于快速識別不同批次材料的粘度變化。同時還包括測量PET（聚酯）和尼龍?zhí)匦哉扯扰c熔體粘度之間關(guān)聯(lián)的程序。

實(shí)時顯示

除其他所有強(qiáng)大功能外，用于Windows™環(huán)境的LAB KARS能夠在測試過程中實(shí)時顯示力或壓力隨時間變化的情況。此功能允許操作人員確定材料的穩(wěn)定態(tài)流動狀況。另外，污染、未熔融的樹脂或材料中的氣泡，都可從壓力與時間曲線中的尖峰處識別出來。

Description

Versatile

The new LCR7000 Series Capillary Rheometers offer many new features and will meet the demands of a 24-hour-a-day shop floor operation while maintaining the highest possible level of accuracy, repeatability and sensitivity. The LCR series rheometers are versatile and easy to use yet they offer the most sophisticated materials characterization, data analysis, and reporting capabilities. The LCR series can be used with a standard load cell and a barrel mounted pressure transducer.

Sophisticated Software

LAB KARS (“Kayeness Advanced Rheology Software”) is the most powerful and easy to use rheological Windows™-based software package available. Just a few of its easily useable features include: Bagley and Rabinowitsch Corrections plus power law, Carreau, Modified Cross and polynomial viscosity models. With this software users can merge multiple data files from shear stress, shear rate, or thermal stability tests. The resident KARS SQC module can be used to quickly identify viscosity variations in different lots of material. A program for the correlation of melt viscosity to intrinsic viscosity, for PET and Nylon, is also included.

Real-Time Display

In addition to all of its other powerful features LAB KARS for Windows™ provides a real time display of force or pressure versus time as a test progresses. This feature allows the operator to identify the steady state flow condition for the material. In addition, the presence of contamination, unmelted resin, or bubbles in the material may be identified from spikes in the force versus time curve.
