Rotary vane vacuum pump used in the industries of resin _

vacuum infusion technology is one of the rotary vane vacuum pump application in the resin company. Vacuum infusion process means resin infusion by the vacuum force. Put the material flat on the mould, and the introduction of resin after vacuum. In order to achieve the perfect vacuum, resin through pipe can infiltrate the laminated layer step by step. The process need to be classified according to different manufacturers and materials. In traditional hand lay-up process, place the enhancement layer on the mould, and through the study of the vacuum of excess resin can greatly improve with the brush, roller and other wetting and compaction in the same way, and vacuum bag can be greatly improved. Improvement. Resin is the main results of the permeability of glass fiber is to make the product more solid and lighter.

the advantages of vacuum infusion technique compared with the traditional technology of vacuum bag, vacuum infusion has certain improvement. Main advantages are as follows:

1. Resin fiber ratio higher

2. Reduce the waste resin

3. Resin using the consistency of the

4. Reduce the preparation time

5. Clean

vacuum infusion technique of fiber resin ratio is superior to the vacuum bag. Vacuum water pump manufacturers will detail next reasons.

traditional hand lay-up process is composed of 100% fiber and resin, single resin is very fragile, so too much resin are actually more vulnerable. Vacuum bag can reduce this problem, but they are unable to solve other problems. Vacuum bag method for hand lay-up is indeed a big improvement, but it is still associated with hand lay-up. Therefore, remain the state of saturated rolling. Vacuum pressure will suck out the excess resin, but most of the removal depends on other factors, such as strengthen, resin, time, etc.

the different ways of vacuum infusion is when using a rotary vane vacuum pump pumping vacuum fiber is still dry. Through rotary vane vacuum pumps force into resin, which is better than inhaled excess resin from the start. At the beginning of the vacuum infusion no resin are introduced. In fact, the excess resin by vacuum tube output, only to introduce the least amount of resin, this reduces weight, increased the strength, and maximally save the resin and fibre. Through the formation of vacuum infusion components can be very flat.

by the amount of vacuum infusion molding resin can be obtained. When standard hand paste resin quantity changes, according to the operation of vacuum impregnation of resin quantity is the same. Even in the manufacturing of large products, the amount of resin are also highly reproducible. Results is to reduce the waste resin, more important is to reduce the waste of money.

vacuum infusion time of another important factor to note. Often the problem is vacuum infusion time. There are a lot of shelf life of the resin is about 30 minutes. Although some resin ( Such as epoxy resin) For a period of 2 hours, but even if this time limit, Shelf life) Also is the key factor for vacuum infusion. A large project is easy to achieve two hours of time limit. When the vacuum leak occurs, even the surface of the small and simple things are not easy to find. When installing a vacuum bag, resin can flow between components.

vacuum infusion no time limit, because pressure layer in vacuum is still, dry, until all the resin. After installation of vacuum bag, will quickly identify leaks, if not appropriate, can refill and readjustment. Time will not stop until it's not filled resin. Until the moment you can make another change.

in the end, the vacuum infusion is a very clean process. Rotary vane vacuum water pump used for resin, without brush or tweezers or spray and spray. Don't need to open mold, saturated laminate will not fall off by hand. In addition, this will reduce the smell of the resin. Because the smell of the resin from the storage of the resin container delivery. Vacuum infusion is a kind of clean, safe and good environment. Although still need to work in a ventilation environment, but it's also important to wear protective equipment and safety equipment.
