     Biodegradation generally refers to the decomposition of microorganisms. Microbial decomposition substances that exist in nature will not cause negative effects on the  environment. The degree of degradation is called degradation index. Biodegradable materials refer to materials that can be completely decomposed by microorganisms (such as bacteria, fungi, algae, etc.) into low-molecular compounds under natural environmental conditions with appropriate and indicative deadlines. Biodegradability is an important property of PBS polyester. At present, the main method for evaluating the biodegradability of plastics in the world is the composting method. Compost contains rich sources of microorganisms, which can macroscopically reflect the biodegradation of plastics in the natural environment to a certain extent. performance. GBPI Compost Degradation Tester can provide compost performance testing of most plastic products on the market.

Importance of compressive strength of packaging bags： Product packaging is prone to stacking cracks and crush damage during transportation and storage. Therefore, the main concern in the field of product testing is the protective effect of packaging. This requires us to formulate a test plan to evaluate the effect of packaging, and continuously improve the design based on the results to achieve the best results-under the premise of meeting product protection: reduce the total cost of product packaging as much as possible, and ensure the hot adhesion of the packaging bag The test is qualified, and the puncture resistance of the packaging bag is improved.It is well known that the packaging bags under stacking will bear a lot of pressure. If the pressure resistance of the packaging is poor, bag breakage is easy to occur. Therefore, it is required that the packaging bag body and the sealing part should have high pressure resistance. This article uses the GBPI compression tester for bag packaging to test the pressure resistance of food packaging bags as an example to introduce the test principle and test process content to everyone. Provide a reference for companies to monitor the pressure resistance of product packaging. Many food factories use inflatable packaging bags. For nitrogen-filled packaging, the food can be placed in a low-oxygen environment, which has the effect of preventing food from oxidative deterioration and mold. However, the gas filled in the packaging has advantages and disadvantages. While protecting the food, it will have a greater impact on the packaging bag when it is squeezed or impacted by external forces, which requires the packaging bag to have higher flexibility. And sealing fastness, so strengthening the test of the pressure resistance of inflatable packaging can effectively reduce the bag breaking rate in the process of stacking and transportation. By simulating the squeezing situation of the test sample stacking, a certain pressure is applied to the sample, and the deformation and leakage of the test sample after being kept under the applied pressure for a certain period of time. In addition, you can also set the pressure value to be applied to the test sample multiple times by testing the maximum pressure, and each setting is increased on the basis of the last force value. After the predetermined number of times is reached, the total deformation of the test sample is detected, etc. Test the compressive resistance of the test sample. compressive strength of packaging bags test process: 5 samples of inflatable packaging bags with intact packaging are randomly selected. Set the test pressure, test time and other parameters. Please note that the pressure cannot be adjusted too high, otherwise it will damage the sensor, it is recommended to adjust to 0.1Mpa first, if the pressure is too low, you can gradually adjust) (1) Take one of the samples and put it between the two test boards of the device, click the test option...

GBPI mask consultant takes you to understand the test process and steps of the synthetic blood penetration test instrument for masks. Mask synthetic blood penetration tester Principle: The synthetic blood permeability tester for masks is used to test the resistance of medical masks, disposable masks and other protective masks to the penetration of synthetic blood under different test pressure levels. Standards: GB/T 19083-2010 Technical requirements for medical protective masks 5.6 Synthetic blood penetration barrier performance YY/T0469-2011 Medical surgical mask 5.5 Synthetic blood penetration test ASTMF1862 Test Method for Resistance of Synthetic Blood Permeability of Medical Masks (Fixed Volume of Horizontal Jet at Known Speed) ASTMF2100 Synthetic blood penetration resistance in the performance requirements of medical masks EN14683 Specifies the structure, design, performance requirements and test methods of medical masks Parameters: 1.Spraying distance: 300mm~305mm adjustable 2.Jet speed: 400cm/s-7000cm/s adjustable Features: 1. The sample is specially customized for the fixing device to simulate the actual use of the outlet cover, and the sample is kept in the special experimental area; 2. Constant pressure spray device, which can spray a certain volume of synthetic blood within a controlled time; 3. It can fully simulate the injection speed corresponding to the average human blood pressure 10.6kPa, 16kPa, and 21.3kPa for testing. Testing process: Fix the mask sample on the sample holder of the instrument, and spray the synthetic blood from the nozzle horizontally to the target area of  the sample to be tested at a distance from the center of the sample at the set pressure, and visually inspect it within 10 seconds after removal. Testing steps: 1.Pull down the sample cover of the instrument, clamp the sample on the fixture, and close the sample holder and protective cover after fixing. 2.Set the relevant parameters (spray pressure and spray time), click [feed] to pour the synthetic blood, adjust the height of the nozzle, and press "[Start]. At this time, spray horizontally toward the tested mask behind the positioning target, and hear With a beep, the instrument automatically stops spraying and the experiment is over. 3.After the test is all over, the synthetic blood residue in the test solution tank is cleaned, replaced with distilled water, and the entire pipeline is cleaned. After the nozzle sprays clean water, continue to drain all the clean water in the test solution tank. Close the outlet valve of the ...
