Metoda badania właściwości żywic aminowych
Żywica aminowa to rodzaj żywicy syntetycznej z grupą aminową, który jest zwykle stosowany w powłokach, kleje, tworzywa sztuczne, 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, wytrzymałość cieplna, weather resistance, chemical corrosion resistance, odporność na zużycie, 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, budowa, elektronika, domu i innych polach.

Simple method
The following is a brief description of the testing methods for common performance parameters of amino resins:
Solidna treść: 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.
Lepkość: Use viscometer and other equipment to measure the viscosity of amino resin solution.
wartość PH: Use PH meter and other equipment to measure the pH of amino resin solution and evaluate its stability and application effect.
Solubility: 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.

Gęstość: Measure the density of amino resin using equipment such as a densitometer.
Stabilność termiczna: The amino resin sample was heated to a certain temperature and its thermal stability was observed for a certain period of time.
Odporność na czynniki atmosferyczne: The amino resin coating or sample is placed in the outdoor environment and its weather resistance is evaluated after a certain period of time.
Odporność chemiczna: The amino resin coating or sample is exposed to chemicals and its chemical resistance is evaluated after a certain period of time.
Twardość: Use equipment such as a durometer to measure the hardness of amino resin.

Particle size distribution: The particle size distribution of amino resin particles was measured using particle size analyzer and other equipment.
Notatka: Different performance parameters may require different testing methods and equipment, mogą też obowiązywać pewne standardy i specyfikacje branżowe, for the performance testing of amino resins, the corresponding testing methods and standards should be selected according to the actual needs. W tym samym czasie, 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.
