MK-819 is one type of pressure spray guns.Nozzle is designed by 6 hole,mainly used for spraying latex paint and colorful paint as well as primer paint.This spray gun comes with 2 air caps, one for spraying colorful paints and one for spraying latex paint and primer paint.
1.FEATURE OF LATEX SPRAY GUN
A: Latex spray gun with wear-resistant nozzle,longer-life span and nozzle designed by 6 holes with much better performance
B:Its strong spraying atomization ability. It can quickly spray our products in different industries in a large area. Greatly improve work efficiency
2.WHAT IS PRIMER SPRAY GUN?
Firstly primer spray gun is high pressure spray guns.What is the difference between a high pressure spray gun and a low pressure spray gun?
Pneumatic spray guns are divided into two types: high-pressure spray guns and low-pressure spray guns according to the size of air consumption. So what is the specific limit for this air pressure?
Usually, we use about 0.2Mpa to judge whether the spray gun is a high-pressure spray gun or a low-pressure spray gun in the daily use process. So what are the characteristics of each of them.
High-pressure spray gun: The air pressure used is about 0.4-0.5Mpa, which is the air pressure range of general pneumatic spray guns. All of this range cannot be called an absolute high pressure gun, of course, it is indeed high pressure relative to low pressure. Its main feature is its strong spraying atomization ability. It can quickly spray our products in different industries in a large area. Greatly improve work efficiency.Therefore,primer spray gun is mainly used for large range of primer painting,like latex paint,sand-in-sand paint and etc.
Low pressure spray gun:It can atomize the paint well under the condition of low air pressure, and can achieve our spraying effect. The most important thing is that the paint will not be scattered in a large area without the rebound force of high air pressure. Thereby increasing the paint rate.
3. HOW TO USE COLORFUL PAINT GUN AND PRECAUTIONS
The decorative effect of colorful paint is the most critical part, and the speed of the spray gun is the key point.
(1) During the water-in-water spraying process, if the moving speed of colorful paint gun is too fast, the surface coating of the water-in-water surface will be thinner, and the coating effect will appear thin, not full, inferior, and the effect will not come out.
(2) If the moving speed of colorful paint spray gun is too slow, the coating will be too thick, resulting in sagging.
(3) The moving speed of the water-in-water spray gun should be such that the coating after spraying is full, uniform and wet. This effect requires experienced construction personnel to make.
2. Control of trigger gun trigger
The trigger is used to control the spray flow rate of the spray gun. The deeper the trigger is pulled, the greater the flow rate of the water-in-water paint. In electrostatic spraying equipment, when the gun is moving, the trigger is always stuck, not half-buckled. In order to avoid the accumulation of paint at the end of the shot, generally experienced construction personnel will slightly loosen the trigger to reduce the amount of material supplied.
3. The position where the spray gun is aimed at
During the spraying process, the spray gun and the wall should be kept vertical or as far as possible, because if the spray gun is skewed, it will cause the spray width to be deviated, the paint will flow to one side, and the other half will be short of paint, dry and thin, and even a striped coating will appear. .
4. The distance from the spray gun to the wall
Generally, for the water-in-water siphon gun, the best working distance is between 15cm-20cm. If the spray gun is too close to the wall, it may cause the paint to flow. If the distance exceeds 20cm, it will easily lead to dry spray or over spray, which will make the paint flow worse. The pressure feed gun can be a little farther away from the wall, but it also needs to be controlled between 20cm-30cm.
5, the posture of the gun holding the gun
The spray gun is controlled by the palm and fingers. Generally, the palm, thumb, ring finger and little finger hold the spray gun, and the middle and index fingers pull the trigger. In actual operation, many construction workers will change the position of holding the gun from time to time during long-term work, and only use the thumb to hold the gun or the ring finger or the little finger, the middle finger and the index finger to pull the trigger. This spraying can greatly relieve fatigue and improve work efficiency.
4. APPLICATION of PRIMER SPRAY GUN:
1.The cup of spray gun MK-819 is only 1000ML,the nozzle size is 2.0/2.5/3.0/3.5/4.0mm so it is mainly used water-in-water and sand-in-water small area proofing and painting
2.It is used for spraying medium and high viscosity of primer paint,like wall latex paint (usually use 2.5mm)
5.FAQ:
Q: What is the volume of this cup?
A: 1000ml
Q: Must i use the air regulator when use this spray gun?
A: yes,it is one type pressure gun,you can see and control the inlet pressure by adjusting pressure gauge
Q: I donot like this black color, is it possible to buy other colors ?
A: Of course,it is no problem to choose other color,like blue or green.
Q: What is MOQ if i want to use my own brand color box ?
A:MOQ is 1000pcs.But there is no MOQ if you only need to put your brand on gun body by laser.
