Protective Clothing Against Molten Metal Tester GT-C94
Product Introduction
Application
It is used to determine the impact performance of high-temperature metal melt droplets in protective clothing and the high-temperature protection performance of textiles.
Standards
AQ 6103-2007, GB/T 17599, GB/T 8965.2-2009, ISO 9150, EN 348
Feature
Generate metal drop device:
① Oxyacetylene torch melting metal wire (stick) one end, welding tip caliber (1.2±0.1)mm; ② The movement of metal wire (stick) control by wheel system motor speed regulation, motor wire feed rate(10±1)g/min; ③ Welding nozzle center vertical with wire (stick), the distance between welding tip and wire(stick) adjustable, usually its 12mm; ④ Droplet weight (0.50±0.05)g; ⑤ Generate droplet frequency 20 drops/(min±3s); ⑥ Start distance from wire to welding burner; ⑦ Length of welding torch deep blue flame core;
Droplet guide mechanism:
① Funnel guide: the angel between guidance axis and vertical adjustable, caliber can through diameter (8±0.2)mm metal strip, add lid on guide slot for it can cover when it not using. ② Holder: bearing and funnel guide, its three dimensional adjustable.
Temperature sensing system:
① Sensor support: refractory insulation material, pyroconductivity is (0.125±0.015）W/（m.K), specific heat 1.15J/ (g.K) groove dimension of surface (13.5×11) mm while 40℃. ② Temperature sensing system: armoured platinum resistor, coating high temperature adhesive, resistance100Ω, Clitheriform, dimension (12.5×10) mm, thermal response time≤0.5s while 0℃. ③ Record display: can display warming and its corresponding droplet no. time, frequency value on sample back; Guide slot test temperature>250℃, temperature rise on sample back≥40K will alert. ④ Precision: resolution ratio≤±0.5K, deviation between temperature display and alert function test ≤±0.4K. ⑤ Structure and install: temperature sensor can contact by groove center nearby two hole's guide line, four sides bolt can fix sensor support on sample frame.
Sample frame:
① Sample holder support can guarantee sample cling to sensor; ② Put（175±5）g pre-tension on sample; ③ The location of sample on vertical and horizontal direction adjustable.
Instrument is equipped with professional computer software.
Oxygen and acetylene gas need to purchase on your local by yourself.
