How many ways does the decoration glue apply?

The decoration glue is mostly used for home decoration, so some application methods, such as dip coating and hot melt adhesive coating, are relatively rare. How many methods are commonly used for decorative glue application?

1. Brushing method is generally applied to the surface of the adherend with a brush or a pen. The brushing method is generally suitable for painting any surface. When brushing, it only needs to follow a direction. Reciprocating, slower, you can avoid bringing in bubbles.

2. Spraying method, using the glue gun to spray the decorative glue on the bonding surface of the adherend, the spraying feature is that the thickness of the rubber layer is relatively uniform, the production efficiency is high, and it is suitable for large-area bonding.

3. Rolling method, firstly dipping into the glue liquid with the roller, and then transferring to the surface to be bonded or coated. The method is uniform in coating, and can be double-sided or double-sided, and the glueing efficiency is high.

4. Injecting method, inject the decorative glue into a special container, and then inject it into the periphery of the joint by hand, mechanical and pneumatic pressure.

Some tips for operating the Square Pipe Polishing Machine

          Square Pipe Polishing Machine is suitable for surface polishing, drawing and sanding of various straight tubes (rods). It can be finished in one time from roughing, fine sanding, throwing linen, throwing cloth, etc. It has the characteristics of stable work and low noise. . Today, the new Chuangsheng industrial polishing machine manufacturers Xiaobian for you to operate some of the tips of the automatic polishing machine.

 

          When operating the automatic polishing machine, it is necessary to accurately grasp the polishing rate. Too fast or too slow will cause damage to the polished object during the polishing process. The use of fine abrasives can greatly reduce the damage caused by polishing, but the polishing speed will also decrease. Polishing in stages can solve the problem of low efficiency. When polishing, rough polishing is performed first, and the damaged layer is ground, and then polished to remove the damaged layer. This not only speeds up the polishing process, but also reduces the damage. The new innovative custom automatic polishing machine spindle speed can reach 2000r/min, the feeding speed can be adjusted 1-5m/min, and the processing range diameter is 5-90mm.

          When the operator polishes the object, it is placed on the fixture, fixed on the workbench of the polishing machine, and then the automatic polishing machine is started to finish polishing. After the completion, the machine will automatically stop, and the operator will unload the polished object. Go down.

How to use electric storage water heater

 1. Water is passed. When using for the first time, pay attention to the hot water valve or hot water tap of the cold water regulating valve, so that the air can be discharged when water is injected. Then, the tap water valve leading to the electric storage water heater is opened to inject water into the water heater, but care must be taken not to drive too much to cause a large impact. Need to wait for the hot water tap or the nozzle to have water flowing out, indicating that the water heater has been filled with water, and then the hot water outlet valve can be closed.

 

  2, power on, check the water supply is normal, set the required water temperature, then plug the power plug into the socket, turn on the power.

  3. After heating, after turning on the circuit, turn on the power switch of the water heater. The heating light is on, indicating normal, and heating starts. The heating lamp is extinguished, the heat preservation lamp is on, indicating that the heating is stopped, and the water temperature can be used as required.

  4, hot water for use, for the use, you can adjust the mixing water temperature, that is, adjust the flow of hot water and cold water.

  When adjusting the water temperature, try to test the temperature by hand, do not directly rush on the body to avoid burns. The enclosed water heater allows continuous operation and automatic temperature control, and the home can be selected as needed. If not needed, the temperature control is not easy to adjust too high to save energy and extend the life of the water heater.

How to maintain vertical vacuum packaging machines

    With the development of the economy, the market for vertical vacuum packaging machines is now expanding and expanding. Vacuum packaging machines continue to introduce new technologies and join the production line, and the degree of automation is getting higher and higher.

 

Vacuum packaging machines use a large number of inflatable packaging to replace the previous vacuum packaging, combining the three aspects of the inflatable packaging machine, packaging materials and inflatable components, and in the control technology, more choices of microelectronics and computer technology.

    Therefore, no matter what equipment is used, relevant maintenance and maintenance are required during use to extend its service life. Vacuum packaging machines are no exception. For vacuum pump oil, it must be kept clear and bright every time it is used. It should not appear turbid or foaming. When the oil is statically precipitated, there will be no milky white matter. If it is, it means that foreign matter enters. Replace with new oil.

The oil level and oil color must be checked once a week. If the oil level is lower than the minimum mark, it means that it needs to be refueled. If the oil level exceeds the maximum mark, some oil needs to be drained, if it is diluted due to too much condensate. For vacuum pump oil, all vacuum pump oil needs to be replaced, and the gas ballast valve can be replaced if necessary.

The exhaust filter needs to be replaced every year. Generally, it can be cleaned with compressed air. The dirt or dust in the vacuum pump needs to be cleaned every six months. The fan wheel, cooling fins, ventilation grille and fan hood need to be cleaned. Compressed air cleaning is recommended.
      The vacuum pump oil should also be replaced in time, and the exhaust filter and the intake filter must be inspected once a month.

Office swivel chair and human health

The main basis of the office swivel chair design is the more natural posture of the human body when sitting, it has many advantages. When a person stands, the joints of the ankles, knees, buttocks and spine of the human body are subjected to the static muscle force to maintain the standing state;

When people are sitting, they can eliminate these muscle strength, reduce body consumption and eliminate fatigue. Sitting posture is more conducive to blood circulation than standing posture. When standing, blood and body fluids will accumulate in lower limbs; while sitting, muscle tissue is relaxed, so that the blood static pressure in the blood vessels of the legs is reduced, and the resistance of blood flowing back to the heart is reduced.

 

Sitting posture also helps to maintain the stability of the body, which is more suitable for fine work. In the case of foot operation, the sitting posture keeps the body in a stable posture, which is conducive to the work, and thus the most commonly used working posture when sitting.
Most office workers, mental workers, and some manual workers now work in a sitting position. As technology advances, more and more manual workers will also work in a sitting position. But there are still many shortcomings in sitting. Limiting the range of human activities, especially in situations where upper limb output is required, often requires standing work, and frequent sit-ups can lead to waste. Maintaining sitting posture for a long time will also affect human health, so the seat design should fully consider the physiological impact on people, and according to the ergonomic design, it can alleviate the sitting fatigue.
