RCH-IV帘线干热收缩测定仪
其采用温控器及传感器,数据采集模块与计算机相连,可测试纤维帘线在一定温度下的收缩率和收缩力,在测试过程中可实时显示帘线的收缩率或收缩力值及曲线,并将各项参数及测试结果保存为数据库,以便用户存档和打印各种报表,测试变简单方便且稳定可靠。
测试原理:
RCH-IV型帘线干热收缩测定仪 是依照国家标准:GB/T 9101-2002、GB/T 9102-2003、GB/T 19390-2003设计制造(符合美国材料试验协会标准ASTM D4974)。试验时将经过调湿平衡的试样,在规定的张力下放置于规定温度的干热空气中一段时间(国家标准规定为2min),测定给定温度下的热收缩率值、热收缩率残值和热收缩力值。
主操作界面
测试方法:
采用先进的加热体移动方式和四工位(可以同时测量两根收缩率样品和两根收缩力样品)设计,通过微机设定仪器的各项参数(所要求的试验温度、测量时间、测量值范围等)。测定过程的数值变化通过屏幕实时显示,由微机自动计算测试结果并可通过打印机打出准确的结果数据和曲线。
测试结果(包括数据和曲线)由微机存储,并可根据需要对试验数据、曲线进行查询、结果打印和数据平均等操作。

Test mechanism:
RCH-IV Cord Dry-heating Shrink Meter is designed and manufactured according to the national standard GB/T 9101-2002、GB/T 9102-2003、GB/T 19390-2003. And it also meets the American standard ASTM D4974, set by the American Society for Testing and Materials. During testing, after humidity equilibration, a sample subjected to a given tension is placed in dry air at given temperature for a designated time (national standard: 2min). Then its heat-shrinking ratio, heat-shrinking ratio residuals and heat-shrinking force are recorded.
Test method:
RCH-IV Cord Dry-heating Shrink Meter can simultaneously measure 2 heat shrink ratio samples and 2 shrink force samples. It is composed of the following parts:
1、Electrical heating and temperature control system;
2、Cord grip system
3、Displacement signal acquisition and processing system
4、Force value signal acquisition and processing system
5、Computer system
6、Weights
The parameters (desired testing temperature, time, range of values) can be set on the computer. During testing the changes in the measurements will be displayed in real time, and the computer will automatically calculate the testing results (data and curves generated), which can be printed then by a printer.
The testing results (including data and curves) will be saved by the computer, and ready to be inquired, printed or averaged as required.
Features:
RCH-IV Cord Dry-heating Shrink Meter is a brand new tester. It incorporates advanced heater movement technology and allows 4 cords to be measured at the same time (ie, 2 for shrinking ratio and 2 for shrinking force), and can therefore promotes the accuracy and efficiency of testing.
RCH-IV Cord Dry-heating Shrink Meter can be used for testing the dry-heating shrink properties of various kinds of cords and threads. It is suitable for studying the heat properties of fiber materials, or for inspection purposes of the tire fiber reinforcing materials, or for determining the calendaring processes of fiber cords.
Technical parameters:
Sample hold capacity:for 4 cords (2 for shrinking ratio and 2 for shrinking force);
Testing temperature continuously adjustable:50℃~250℃;
Shrinking ratio testing range:~+40%;
Shrinking force testing range:0~30N;
Shrinking force testing precision:<0.2%;
Working power:220V /2A/50Hz。
