Что вы знаете об испытаниях работоспособности малярной пасты??
Цветная паста представляет собой высококонцентрированную формулу покрытия., состоит из пигментов, наполнители, диспергаторы, разбавители и другие компоненты, which can be mixed and deployed with the base coating in proportion to achieve the desired color and effect. Paint color paste is widely used in construction, мебель, автомобиль, electrical appliances and other fields, providing more color selection and customized services, as well as the advantages of cost saving and efficiency. The quality and stability of paint color paste have an important impact on color accuracy and coating quality, so it is necessary to carry out quality inspection and control.
The paint color paste needs to test the following properties:
| Производительность | Объект проверки |
|---|---|
| Разница в цвете | The color difference between the paint color paste and the standard color sample |
| Stability of color | Color stability of paint paste, например, изменение цвета, stratification, precipitation, и т. д. |
| Ликвидность | The flow performance of paint color paste, such as drying time, выравнивание, и т. д. |
| Степень вязкости | The viscosity of paint paste |
| Стабильность | The stability of paint paste, such as suspension, precipitation, и т. д. |
| Другой | Such as paint paste resistance to precipitation, скрывающая сила, и т. д. |
Метод обнаружения:
Разница в цвете: use color difference meter, optical wavelength meter and other equipment to test the color difference between the paint paste and the standard color sample.
Стабильность цвета: through artificial aging test, constant temperature and humidity test and other methods to test the color stability of paint paste.

Fluidity: using reverse flow cup method, diffusion cup method and other methods to test the flow performance of paint paste.
Вязкость: Use viscometer, rheometer and other equipment to test the viscosity of paint paste.
Стабильность: through centrifugal test, settlement test and other methods to test the stability of paint paste.

Другие: according to the specific type of paint color paste and testing items, select the appropriate test method and equipment for testing, such as testing the anti-precipitation of paint color paste, скрывающая сила, и т. д..
The results of these test items can help evaluate the quality and applicability of paint colorants and how well they will perform in practical applications. Test methods and equipment are different according to the specific type of paint paste and test items. The performance test of paint color paste should be carried out in accordance with relevant standards and methods to ensure the accuracy and comparability of test results.
