  Reasons for low transmittance and pure water volume of spraying production line Spraying is a kind of processing for products that need to be covered with a protective layer and a decorative layer on the surface. In the  spraying production line , the transmittance and pure water are sometimes low. What causes it? 1. Reasons for the low transmittance in the spraying production line In the ultrafiltration equipment, the flow rate of the tank liquid is low, the pressure setting changes, the coarse filtration is insufficient, and the equipment is often stagnated (the equipment stops running for more than 1 hour), which will reduce the permeation volume and may even cause the ultrafiltration membrane to be damaged. Failure of the activation layer of the ultrafiltration membrane: The activation layer converts the polarity of the charged material into the same polarity as the bath itself. Its effect is limited by time, and its durability can reach several months under conditions. ...

  The spray gun is a crucial part of the   automatic spraying machine   which needs to be maintained regularly. If the maintenance is improper, the spray gun will be prone to problems, thus undermining the spray finishing effect. Richfruits has decades experience of maintaining spraying gun in auto spray coating machines, and therefore concludes several tips about spraying gun routine maintenance: Richfruits Source: https://www.rffinishing.com/ Location: China Year Founded: 2003 Company Type: Manufacturer Key Products: A utomatic spraying machine 1. First of all, maintenance crews need to frequently check the needle valve, air valve, and gasket seals for leaks. If leak is found, it should be replaced in time. Furthermore, remember to  apply lubricate oil on the sealing gasket regularly to make it soft and easy to slip. 2. The thread of the air cap of the spray gun, the spray paint volume adjustment knob, and the valve adjustment knob should be oiled frequently to ens...

  Daily cleaning of coating equipment The equipment in the  coating production line  must be cleaned after being used for a long time, so how should the coating equipment be cleaned? Today, the Richfruits coating equipment manufacturer will introduce how to clean the coating equipment. The daily cleaning of the coating equipment ultrafiltration machine is divided into physical cleaning and chemical cleaning Physical cleaning mainly includes forward washing, back washing and air washing. 1. Positive washing: Positive washing is to open the water inlet valve and close the water production valve, so that the high flow rate of the flushing liquid is discharged from the concentrated water, so as to clean the surface of the membrane at a high speed and reduce the contaminants on the membrane surface. 2. Backwashing: This operation is the opposite of filtration, that is, the backwash water enters the ultrafiltration fiber from the side of the cleaning liquid, flows through the m...
