The characteristics and how to choose the uniform rubber machine

0 Comments

The rotating coating technology is generally used by the equipment. There are many kinds of titles of the even glue machine. The English is called spin coater or spin processor. Rotating coating instruments, rotating coating instruments, and uniform membrane machines, in general, their principles are the same, that is, on high -speed rotating substrates, drip various types of rubber fluids, and use centrifugal force to make the glue drip on the substrate on the substrate The liquid is evenly coated on the substrate. The thickness is different depending on the stagnation coefficient between different rubber fluids and the substrate, which is also related to the rotation speed and time. Wenyu provides imported and domestic uniform gel machines. The product is customized. The speed range is 0 ~ 8000 rpm and the size of the uniform glue is 8mm-8 inches.

From its principle, the uniform rubber machine has the following two characteristics:

(1) Rotating speed

The speed and control accuracy of the speed directly affect the thickness control of the rotary coating and the uniformity of the membrane layer. If the speed marked speed and the actual speed error of the motor are large, it is impossible to obtain accurate experimental data for scientific researchers who require precision coating. At present, there are international identification standards, such as the US NIST standard.

(2) Vacuum adsorption system

The vacuum pump is generally used in oil -free pumps, which is usually the dry pump, because any oil may block the vacuum pipeline. If the vacuum adsorption power is reduced, it will cause the substrate to absorb Increased glue into the vacuum pipeline system caused completely blockage. Some uniform rubber machines do not start rotating when the vacuum adsorption force is not enough. This can effectively avoid dripping gums from accidentally entering the vacuum pipeline system.

In general, their principles are the same, that is, on the high -speed rotating substrates, drip various types of rubber fluids, and use centrifugal force to make the rubber drip on the substrate evenly coated on the substrate. Different from the sticky coefficient between the substrate, it is also related to the rotation speed and time.

How to choose a lighter

1. Rotation speed: The speed of speed and control accuracy of the speed directly affect the thickness control of the rotary coating and the uniformity of the membrane layer. If the speed marked speed and the actual speed of the motor are large, if the graphic is very different, it is impossible to obtain accurate experimental data for scientific researchers who require precision coating. Most of the domestic low -end uniform machines can only provide a speed range, and cannot calibrate the real -time speed.

2. The structure of the vacuum adsorption system

The vacuum pump must be no oil, the pressure is accurate, and the domestic oil -free real vacuum pump is really dare not compliment. Because any oil may block the vacuum pipeline. If the vacuum adsorption force is reduced, it will cause the substrate to adsorb and produce a “flying tablet”. It will also cause the titer to accidentally enter the vacuum pipeline system to cause completely blockage. Customers who have used domestic uniform rubber machines often care about how to clean them. Many foreign uniform gel machines do well. They have a linkage mechanism. If the vacuum adsorption force is not enough, it will not start to rotate.

3. Material selection

For the application of the semiconductor chemical industry, the selection of materials is particularly critical. Most of the domestic uniform machines use iron plate paint or ordinary plastic material, because the cost of this material is very low. If this deformation causes the position of the tray to lose the level, it will cause a bumpy state of the time when the rotation is high. Naturally, it is impossible to get a good rotation effect. Some foreign brands are currently made of natural polypropylene or polytimonin (Teflon). These two materials have the advantages of green environmental protection, saving resources, light weight, strong strength, good impact resistance, strong durability, natural pattern, and good gloss.
