The role of high-voltage power supply in mask production
As early as 15 years ago, the electret equipment used in melt-blown non-woven fabrics (melt-blown non-woven fabrics), especially the high-voltage power supply used in melt-blown non-woven fabrics, was monopolized by foreign countries. More than 70 years ago, there were already high-voltage power supply manufacturers in foreign countries. Today, these foreign manufacturers have become international multinational companies, and high-voltage generators dedicated to electrostatic electrets are only a small category, and the market has long been occupied by foreign countries. .
Domestic users have the first priority and try their best to purchase foreign high-voltage power supplies, even though foreign equipment is expensive, has long delivery times, and is not timely after-sales. Domestic high-voltage power supply manufacturers can only do some orders that others are not willing to do. Others eat meat, but we gnaw on the bones and slowly accumulate market reputation.
Until the outbreak of the new coronavirus pneumonia (COVID-19) in 2020, the use of masks has greatly increased, the mask production line is very tight, and the demand for melt-blown non-woven fabrics has exploded, followed by electrostatic electret equipment dedicated Bulk purchases of high voltage power supplies.
It stands to reason that foreign power supplies have a high market share and a good reputation, which is a good opportunity, but the 2 to 3 month supply cycle is unacceptable. The domestic epidemic situation is extremely urgent. Not to mention 2 months, even 2 days will have unknown consequences. In this situation.
According to data given by the power supply manufacturer, as of the end of February, more than 100 dedicated high-voltage generators had been provided to the melt-blown nonwoven industry in just one month. These more than 100 pieces of equipment were used in nearly 100 production lines. A production line can produce as little as 1.5 tons of non-woven fabrics a day, or as much as several tons. One mask requires 1~2g of melt-blown fabric. One ton of meltblown cloth can provide the core layer for 750,000 to 1.5 million masks. It is conservatively estimated that the high-voltage power supply provided by Tesman High Voltage Power Supply can produce 50 million masks.
