Introduction Battery Diaphragm Gas Permeability Tester N600E is designed and developed according to GB/T 36363-2018 and other standards. It adopts the test principle of differential pressure method and is professionally used for testing the air permeability of battery separators, breathable membranes and related polymer materials. Test principle In the environment of test temperature, humidity and normal pressure, under the pressure of 1.21kPa applied by the test instrument, the time required for 100mL air to pass through the diaphragm with an area of 6.45 cm2.   Standard ISO 5636-5, TAPPI T460, GB/T 36363 Specification Test range 60~12000 s/100mL Resolution 0.1 s/100mL Pressure range 0~3 KPa Pressure resolution 0.001 kPa Test area 6.45cm2 Sample size ＞50 mm×50 mm Instrument Size 450 mm×400 mm×300 mm Power 100W Power supply 110~250 VAC, 50~60 Hz   Features     The pressure difference of the instrument is adjustable in the range of 0~3 kPa, with an accuracy of 0.001 kPa, which fully meets the test pressure difference requirements of different methods;     The instrument supports s/100mL and um/(Pa.s) multi-unit display.     The test range can be customized according to different sample requirements.     The host is equipped with a color touch screen, no need for an external computer, and the air permeability of the sample can be observed in real time; Built-in micro-printer, which can print test report in real time; Application   Lithium Ion Battery Polyolefin separator for lithium ion battery, coated polyolefin separator for lithium ion battery or separator for lithium ion battery using other materials  

Film Heat Shrinkage Tester tests various heat shrinkage properties for the film according to the principle of air heating (air bath). Suitable for heat shrinkable films which produced with polyethylene, ethylene copolymers and their mixtures, such as beverage labels, bottled bundle packaging, sausage shrinkage packaging, outer film of daily chemical products, outer film of cigarette boxes, etc. It is a device that can accurately and quantitatively measure the thermal shrinkage force, cold shrinkage force, shrinkage rate, shrinkage time and other properties of plastic films during thermal shrinkage. The test results have a variety of data, which can evaluate the heat shrinkage performance of the film from different aspects, contribute to the research and development of heat shrinkable films of different materials, ensure the stability of heat shrinkable films performance of various materials, and meet the requirements of various heat shrinkable films in various industries. GBPI checks the key thermal shrinkage properties of film products for you. The traditional oven or oil bath equipment only detects the heat shrinkage rate of the heat shrinkable film, and the test results are relatively limited. Our Film Heat Shrinkage Tester GBK-D1 can evaluate the thermal shrinkage performance of films from various data. It is easy to operate, environmentally friendly, with high data accuracy and more comprehensive test results to meet your requirements.
