Test method for properties of amino resins
Amino resin is a kind of synthetic resin with amino group, which is usually used in coatings, lijmen, kunststoffen, 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, hittebestendig, weather resistance, chemical corrosion resistance, slijtvastheid, 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, elektronica, huis en andere velden.

Test method for properties of amino resins
Simple method
The following is a brief description of the testing methods for common performance parameters of amino resins:
Solide inhoud: The amino resin sample was heated to a certain temperature and dried to a constant weight, en de verhouding van de massa niet-vluchtige stoffen tot de totale monstermassa werd berekend.
Viscositeit: Use viscometer and other equipment to measure the viscosity of amino resin solution.
PH waarde: 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.
Test method for properties of amino resins
Dikte: Measure the density of amino resin using equipment such as a densitometer.
Thermische stabiliteit: The amino resin sample was heated to a certain temperature and its thermal stability was observed for a certain period of time.
Weersbestendigheid: The amino resin coating or sample is placed in the outdoor environment and its weather resistance is evaluated after a certain period of time.
Chemische weerstand: The amino resin coating or sample is exposed to chemicals and its chemical resistance is evaluated after a certain period of time.
Hardheid: Use equipment such as a durometer to measure the hardness of amino resin.
Test method for properties of amino resins
Deeltjesgrootteverdeling: The particle size distribution of amino resin particles was measured using particle size analyzer and other equipment.
Opmerking: Different performance parameters may require different testing methods and equipment, en er kunnen enkele industriestandaarden en specificaties zijn, for the performance testing of amino resins, the corresponding testing methods and standards should be selected according to the actual needs. Tegelijkertijd, 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.
