Plasticizer is widely used in industrial production of polymer materials, also known as plasticizer.
Any substance added to a polymer material that increases the plasticity of the polymer is called a plasticizer.
Plasticizer can improve the performance of polymer materials, reduce production costs and increase production benefits.
Is a kind of important chemical products additives, as additives commonly used in plastics, concrete, mortar, the material such as cement, gypsum, cosmetic and detergent, especially in PVC plastic products, in order to increase the plasticity of the plastic and improve the strength of the plastic, you need to add phthalic acid ester, sometimes its content can be up to 50% of the products.
Weakened the effect of plasticizer mainly resin molecular valence bond between time, increase the mobility of the resin molecular bonds, reducing resin molecular crystalline, increase the plasticity resin molecules, enhanced the flexibility, easy to machining, can legally used for industrial purposes, widely exists in food packaging, cosmetics, medical equipment, water and environment.
Such as plastic wrap, food packaging, toys and so on.
Plasticizer will fill in the test sample cup to liquid level scribed line, the original rapidly increases the sample temperature, and then slowly to stabilize the speed c to close to the flash point of plasticizer (SH106B automatic flash tester), within the prescribed time to time to test under the temperature of the small flame swept through back to the surface of the liquid in the cup, when the fire caused by the liquid vapor flash on the surface of the flash point is the minimum temperature.
Plasticizer flash point should affect the processing temperature.
SH106B automatic plasticizer opening flash point tester (developed and produced by Shandong Shengtai Instrument Co., LTD.) is designed and manufactured according to the requirements stipulated in the People's Republic of China standard GB/T 3536 "Flash point and ignition Point determination method for Petroleum Products (Cleveland Open Cup Method)".
The instrument is heated according to the standard method, automatic lifting, automatic ventilation, automatic ignition, automatic display, automatic locking flash point value, automatic printing results.
After the completion of the test can be automatically cooled, the work process to achieve full automation.
It has the advantages of accurate measurement, good repeatability, stable performance and simple operation, and also supports the determination of flash point of GB/T1671-2008 plasticizer
The instrument features
1. The instrument adopts large color LCD screen display, full Chinese man-machine dialogue interface, no marked keyboard, and has prompt menu and guided input functions for parameters such as prevalue temperature, sample label, atmospheric pressure, test date, etc.
2. Function curve of simulated tracking display temperature rise and test time, with the function of prompt modification of Chinese misoperation software, and parameter prompt function of test date, test time, etc.
3. Automatically corrected the influence of atmospheric pressure on the test and calculated the correction value.
4. Differential detection and automatic correction of system deviation.
5. Scan, detect and print data automatically, and the test arm automatically rises and falls.
6, electronic ignition, forced air cooling
7. Automatic ignition of air source is not required, which improves the safety of the test
