طريقة اختبار خصائص الراتنجات الأمينية
الراتنج الأميني هو نوع من الراتنجات الاصطناعية مع المجموعة الأمينية, والذي يستخدم عادة في الطلاءات, مواد لاصقة, البلاستيك, 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, مقاوم للحرارة, مقاومة الطقس, مقاومة التآكل الكيميائي, ارتداء المقاومة, 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, بناء, إلكترونيات, المنزل وغيرها من المجالات.

طريقة اختبار خصائص الراتنجات الأمينية
Simple method
The following is a brief description of the testing methods for common performance parameters of amino resins:
محتوى صلب: The amino resin sample was heated to a certain temperature and dried to a constant weight, وتم حساب نسبة كتلة المواد غير المتطايرة إلى إجمالي كتلة العينة.
اللزوجة: Use viscometer and other equipment to measure the viscosity of amino resin solution.
قيمه الحامضيه: Use PH meter and other equipment to measure the pH of amino resin solution and evaluate its stability and application effect.
الذوبان: 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.
