AUTO GBDA-180 Compost Degradation plastics test equipment

Product introduction

AUTO GBDA-180 The Compost Degradation Tester is based on the gravimetric method for

measuring carbon dioxide emissions. It is a professional use of small reactors to determine the final biodegradability of test materials. It is suitable for the biodegradability analysis of degradable plastics and bio-based materials such as lunch box garbage, waste ground film, plastics containing plasticizers and pigment additives, etc

Testing Principle

    The test material of this method is a mixture of inoculum of decomposed compost and inert materials (such as sea sand and vermiculite). By controlling the humidity, oxygen permeability and temperature of the compost container, the sample to be analyzed in the reaction chamber is under the action of microorganisms. The biodegradation reaction is carried out through respiration, and oxygen becomes carbon dioxide and is discharged through respiration. The amount of carbon dioxide released is measured by weighing the absorption device equipped with soda lime and sodium talc, and the decomposition rate is calculated by regular measurement.

Film Heat Shrinkage Tester GBK-D1 DIN 53369-1976 Pet Film Heat Shrinkage Tester Thermal Shrinkage Tester For Plastic/PVC /OPS Film

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.
