Detectieprestaties van coatingbasismateriaal en specifieke detectiemethode daarvan

Het basismateriaal van de coating verwijst naar het materiaal dat als basis en drager in de coating wordt gebruikt, inclusief hars, oplosmiddel, vulmiddel, additive, enz. Coating base material is the main source of coating properties, which has an important influence on the quality and properties of coatings. Under normal circumstances, the coating substrate needs to have certain adhesion, vloeibaarheid, duurzaamheid, chemical stability and other characteristics to ensure the effect and durability of the coating in the application process. Common coating substrates include organic solvents, water-based resins, solvent-based resins, powder coatings and so on.

Detectieprestaties
The performance testing items of coating base material vary according to the specific type of base material, and generally include the following aspects:

Fysieke eigenschappen: density, viscositeit, vloeibaarheid, drying time, enz.

Chemical properties: chemical stability, acid and alkali resistance, waterbestendigheid, enz.

Mechanical properties: hardheid, kracht, elastische modulus, enz.

Thermal performance: high temperature resistance, thermal conductivity, enz.

Optische eigenschappen: transparantie, reflectivity, enz.

Detectiemethode
The performance testing method of coating base material varies according to the type and performance parameters of the base material. The following takes several common performance parameters as an example to briefly introduce the testing method of coating base material:

Dikte: The density meter is usually used for measurement, loading the sample into the density meter and reading the density value on the display.

Viscositeit: Can be measured using a variety of methods, of which the commonly used is the rotary viscometer, you can also use the direct drawing method, drip method, enz.

Chemical stability: The sample is exposed to a specific environment, such as high temperature, high humidity, acid and alkali environment exposure test, observe the changes of the sample in different environments, zoals kleurverandering, physical property change, enz.

Hardheid: Use a hardness tester or Rockwell hardness tester to measure.

Kracht: Using equipment such as tensile testing machine or compression testing machine for measurement, the sample is placed in the equipment, the corresponding force is applied, and the change of the sample under different forces is measured to obtain its strength value.

High temperature resistance: The sample is exposed to a high temperature environment, such as exposure in a constant temperature oven for a certain time, and the changes of the sample are observed, such as weight changes, appearance changes, enz.

Transparency: The transparency of the sample is obtained by using a device such as a light transmitter, where the sample is placed in a light transmitter and the intensity of light passing through the sample is measured.

Electrical properties: The use of dielectric constant tester, conductivity meter and other equipment for measurement, the sample is placed in the equipment, electrical properties test, so as to obtain the corresponding performance parameter values.

North and South tide reminds you: the performance testing method of the coating base material varies according to the type and performance parameters of the base material, en er kunnen enkele industriestandaarden en specificaties zijn, for the performance testing of the coating base material, you should also choose the corresponding testing method according to the actual needs. Tegelijkertijd, in order to ensure the accuracy of the test results, the test equipment should be calibrated and maintained before the test.
