What causes orange peel in paint, and how to stop and fix it.
It is possible to see orange peel on painted and cast surfaces.The texture of the orange peel resembles that of an orange.The paint on the body of a car should dry into a smooth surface after being sprayed.The texture of an orange peel can be caused by various factors.Changing the painting technique or the materials used can prevent the orange peel phenomenon from occurring.The cause of orange peel is the result of improper painting technique, and is caused by the quick evaporation of thinner, incorrect spray gun setup (e.g., low air pressure or incorrect nozzle), spraying the paint at an angle other than perpendicular, or applying excessive paint.
The orange peel texture is desirable in some situations.A spray gun is used to apply a texture paint.The paint is applied to the texture.When painting walls, orange peel can develop by using a roller with too little paint or too thick a paint and the surface dries before the texture can level.
The instruments were used to measure orange peel.The instruments look like our eyes.The texture or waviness of a surface can be measured with two types of instruments.
The orange peel meter uses a laser point light source to illuminate the specimen at a 60 angle and a detector to measure the reflected light intensity at the equal but opposite angle.The instrument measures the optical profile of the surface across a defined distance.The structures are analysed by the instruments.The measurement signal is divided into several ranges using a mathematical function.
The instruments use a camera to measure the diffuse light caused by the smaller structures.This is referred to as dullness.
The structure spectrum is formed by the values of dullness and Wa.A detailed analysis of orange peel can be done.An example of a structure spectrum.
The detailed information of the structure spectrum as well as LW and SW became the basis to correlate to specific scales.
