Application of LUMiSizer® Stability Analyzer in Adhesives
An adhesive is an organic or inorganic, natural or synthetic substance that can bond together two or more homogeneous or heterogeneous parts (or materials) and has sufficient strength after curing. It is called adhesive, adhesive, and is often referred to as glue or glue. The synthetic adhesive consists of a main agent and an auxiliary agent, and the main agent is also called a main material, a base material or a binder; the auxiliary agent has a curing agent, a diluent, a plasticizer, a filler, a coupling agent, an initiator, a thickener, The antioxidant, the polymerization inhibitor, the stabilizer, the complexing agent, the emulsifier, and the like may further include a flame retardant, a foaming agent, an antifoaming agent, a coloring agent, and an antifungal agent according to requirements and uses. The method for detecting the stability of the adhesive is usually to observe the appearance or coating after storage for a certain period of time to determine that the viscosity and strength do not change, which requires natural placement for 3 months, 6 months, 12 months, which is uneconomical; The heat aging acceleration method was carried out for measurement. Using the LUM stability analyzer, the process of changing the transmittance of the entire sample over time can be recorded while the sample is being centrifuged, thereby obtaining a complete separation process of the sample, and the instability of the adhesive can be obtained in a short time. Sex index value. This method is in full compliance with the international standard ISO-13097 - Guidelines for the characterization of dispersion stability. Sample: 3 kinds of water-based adhesives prepared under different processes of the same type Photograph of the sample after it has been sampled and loaded into the sample tube Photo taken after the sample is placed in the instrument Purpose: Quickly compare the stability between adhesives of the same type Method: Experiment with higher speed and lower speed under two different temperature conditions with LUMISizer® stability analyzer Test1: SOP: 40°C, 2h, 2300 g Test2: SOP: 25°C, 2h, 2300 g Test3: SOP: 40°C, 14h, 300 g Test4: SOP: 25°C, 14h, 300 g Comparison of the instability values ​​of three groups of samples at high speed, high temperature 45 °C and normal temperature 25 °C Comparison of the instability values ​​of three groups of samples at low speed, high temperature 45 °C and normal temperature 25 °C summary: With the LUMiSizer® stability analyzer you can achieve: 1, record the complete kinetics of sample phase separation 2, greatly shortened the time compared to the traditional observation method for several months 3, you can get quantitative results quickly 4, the sample is used in a small amount and does not need to be diluted 5, multi-sample analysis, zui can place 12 samples at the same time 6, temperature control range up to 4-60 ° C Dietary supplements take vitamins, minerals and extracts with relatively clear structure-activity relationship as the main raw materials, and supplement the necessary nutrients and biologically active substances for the human body through oral intake to achieve the purpose of improving the body's health and reducing the risk of disease.
