Two-component coating:
There are two types of component A
1 is suitable for dark brown paint (chemical fiber blended polyester fiber drawing, air spinning top roller and hard top roller above 80 degrees)
2 Suitable for light yellow (or colorless) paint (cotton, pure cotton, high-count cotton and soft leather rollers below 75 degrees)
Group B is the A component of colorless two-component coatings. The main chemical components are dichloromethane and triisohydrophenol thiophospholipid. The appearance of group B is colorless and transparent solution, and the main chemical composition is trichloroethylene (about 95%) paint.
After the AB paint is matched, the machine cannot be stopped, the spinning roller is applied to the board, and the drawing roller is applied to the pen. If the interval between one side and the other side is to be grasped well, it is about 1 hour without an oven, and about 30 minutes with an oven. Otherwise, the penetration effect of the rubber roller will be affected.
1 Hard and soft rubber rollers have good penetration effect, but hard rubber rollers have poor penetration effect.
2 Smoothness: The surface finish of the top roller is not good, and the penetration effect is poor.
3 Top roller formula: Top rollers with low rubber content have poor permeability
4 Paint The permeability of colored paint is not as good as that of colorless paint (colored paint is prone to redness)
5 Top roller cycle The longer the use time, the worse the permeability of the top roller
6 Paint ratio The thicker the paint ratio, the worse the permeability
7 How to paint. The effect of pen coating is better than that of plate coating, but the output of pen coating is not as good as that of spinning roller. If you grasp it well, you can put the return roll into the oven to preheat for half an hour. Can improve the penetration effect of the rubber roller. The UV irradiation time depends on the number of treatments, the quality of the rubber roller and the hardness of the rubber roller after treatment, the materials used, the spinning quality requirements and the temperature and humidity conditions of the workshop. The irradiation time is determined according to the user’s requirements.
There are generally two aspects to the winding and maintenance of the top roller
1 The temperature, humidity, raw materials, management, regular maintenance, and spinning count of the workshop are all objective factors. Only when the top roller needs to understand, know, and even get ideal data through experiments, can it make useful data. Top roller.
2 To make a top roller, you need to know how much temperature and humidity and what proportion of paint to use. What hardness do we need for spinning? What kind of top roller is suitable. There are many types of marshmallows, how to deal with the top rollers, what kind of top rollers are used for spinning good yarn and trash yarn. What kind of coating and hardness should be used for spinning cotton in winter and summer. What kind of paint and hardness should be used for spinning flower strings in winter and summer. The relationship between the size of the top roller and the pressure should be grasped.
