How Do You Avoid Moisture Pollution?


There are three things you need to do to prevent contaminated (wet) powder from slowing down or stopping your blasting operation:

1. Store powder properly
Always make sure containers (bags or bottles) remain tightly closed when not in use. storing powder in a cool, dry location avoiding wide variations in temperature to prevent the abrasive media from absorbing moisture from its surrounding environment.

2. Clear powder from the tank before leaving
The tank is not a sealed container, even with the machine off and depressurized. leaving powder in the tank for a day or two can cause the powder to absorb enough moisture from the air source of  workshop to clump.

3. Keep your air supply dry
Dirty air is the single greatest root from air compressor—not only with abrasive but with your MicroBlaster. you must install adequate compressed air treatment system to prevent contaminants including oil, water and other particulate matter, such as pipe scale from reaching your machine, and it is essential that you inspect and maintain your air compressor, air dryer, filters on a regular basis. carefully follow all of the manufacturer’s instructions.

Separators are not enough
Separators, which remove liquid by forcing the air stream to spin or change direction, efficiently remove liquid droplets but not sub-micronic oil aerosols and water vapor.



Coalescing filters are not enough
Coalescing filters capture liquid droplets in a bed of fibers. The captured droplets move along the fibers, coalescing into larger droplets which drain to the bottom of the cartridge for removal. These fibers are adequate for providing virtually oil free air, but they are no more effective on water vapor than separators.



Refrigerant dryer are not enough
This type of dryer is insufficient for MicroBlasting.  Most common refrigerant dryers is +35˚C compressed air dew point.  water vapor still more than six times required for trouble-free operation in your blasting system.



Deliquescent dryers are not enough
Deliquescent dryers contain a chemical that melts away as it absorbs water vapor. these types of dryers can only drop dew point by about 20 ˚C from inlet temperature. that means, if used it in conjunction with a refrigerant dryer, you may get a dew point of somewhere between 0˚C~ +10 ˚C, this is still not adequate for most micro-abrasive blasting operations.




Biteman modular-units desiccant dryer and high precision filter---which is not only provide technical support for completely solving water, oil, dust in compressed air and other issues, and also greatly reduce energy consumption much than traditional purification equipment. Heat-less models need 5% regeneration gas consumption, micro-heat models only need 2% re-gas consumption, greatly reducing energy consumption and production costs.



Please directly call 0755-27579401, If you are interested or have any questions about biteman modular-units dryer.

Modern Planning in the Field of Compressed Air

图片
In the past, people only consider the initial investment and operating energy costs such as some simple economic factors, they often overlook the influence pollutants in the compressed air for system when established a compressed air system , thus ignoring the compressed air quality (it can not reach standard will bring huge invisible waste for enterprises), and these losses are often much higher than the high quality purchase and operating costs of purification equipment. Perhaps many companies believe that compressed air equipment just little impact when select ordinary one, but what will actually appear on us? In the 1980s, the industry lagged far behind today, the developed countries put forward ISO8573 standards for the purity of compressed air as for different gas equipment, while it failed to supply the gas equipment standard of compressed air, which caused serious impact, such as shorten the service life, decrease accuracy, increase failure rate, poor quality, and the safet

The Importance of Brand Awareness

图片
Brand is an invisible asset for the enterprise, it’s also the most valuable wealth. in the rapid development of the modern life, the difference become shrinking for product performance, quality, sales service from different enterprises, so the brand will become the main factor to choose products for consumer. "Stupid businessmen sell products, smart businessmen sell brand" This sentence fully illustrates the importance of the brand for the enterprise . therefore, companies should have enough brand awareness, and strive to run the business brand. it is the core content of the product, and brand awareness isn’t all other means of marketing, such as Atlas, Ingersoll Rand, Sullair, Kobelco, etc. these enterprises prefer to brand recognition rather than products identification , and it’s also become the only element of market choice. Brand not only refers to the product quality, but also includes the appearance, technology, function, utility and others, it need long-term accumulat

“Throw a sprat to catch a herring" to get the maximum benefit in a short period

There is a question, why do we establish business? Companies just considering saving cost regardless of construction of enterprises, but it real should need the cost of consumption. later hear a manager says to the subordinate, " I have to find ways to earn back for company spent every penny", perhaps this is a lot of top management staff thought, which is good point for a top manager, then we will be reach the business target to obtain the greatest benefits in a short period.  It is not so easy to realize how to get the maximum benefit in a short period. such as a lot of leading brands seem to be impeccable, while the leading brand's business is far less flexible than some small businesses for imbalanced development of different regional market, much longer product line, and imbalanced development in different products. it is difficult to develop appropriate products and marketing strategy according to local conditions due to consider the national market.
