Метода испитивања својстава амино смола
Амино смола је врста синтетичке смоле са амино групом, који се обично користи у премазима, лепкова, пластике, coatings and other fields. Its main components are formaldehyde and amino compounds, such as urea, melamine and so on. Amino resin has excellent physical and chemical properties, such as hardness, heat resistance, отпорност на временске услове, chemical corrosion resistance, отпорност на хабање, and has good coating, coating adhesion and good gloss and other characteristics. Because of its good properties and diversified application characteristics, amino resin is widely used in automotive, construction, електроника, home and other fields.

Метода испитивања својстава амино смола
Simple method
The following is a brief description of the testing methods for common performance parameters of amino resins:
Садржај чврсте материје: The amino resin sample was heated to a certain temperature and dried to a constant weight, and the ratio of the mass of non-volatile substances to the total sample mass was calculated.
Вискозност: Use viscometer and other equipment to measure the viscosity of amino resin solution.
пХ вредност: Use PH meter and other equipment to measure the pH of amino resin solution and evaluate its stability and application effect.
Растворљивост: The amino resin sample is added to a specific solvent, shaken or stirred and then left to observe the dissolution of the amino resin and evaluate its solubility.
Метода испитивања својстава амино смола
Густина: Measure the density of amino resin using equipment such as a densitometer.
Термичка стабилност: The amino resin sample was heated to a certain temperature and its thermal stability was observed for a certain period of time.
Отпорност на временске услове: The amino resin coating or sample is placed in the outdoor environment and its weather resistance is evaluated after a certain period of time.
Хемијска отпорност: The amino resin coating or sample is exposed to chemicals and its chemical resistance is evaluated after a certain period of time.
Hardness: Use equipment such as a durometer to measure the hardness of amino resin.
Метода испитивања својстава амино смола
Расподела величине честица: The particle size distribution of amino resin particles was measured using particle size analyzer and other equipment.
Белешка: Different performance parameters may require different testing methods and equipment, и можда постоје неки индустријски стандарди и спецификације, for the performance testing of amino resins, the corresponding testing methods and standards should be selected according to the actual needs. Истовремено, it is necessary to strictly control the test conditions and standardize the operation during the experiment to ensure the accuracy and reliability of the test.
