After experiencing this difficult period of pneumonia epidemic, I believe many friends in the future will have their parents keep a few packs of masks on hand to prevent situations where they spend a lot of money to buy masks again. Today, air heater manufacturers will come to talk to you about the machine for making masks - the melt blown heater. It uses high-speed hot air flow to stretch out the polymer melt flow from the extrusion die nozzle hole, forming ultrafine fibers, which are gathered on the condensation mesh or roller and bonded into melt blown nonwoven fabric. What are the performance characteristics and power consumption of melt blown pipeline heaters? Today, we will introduce the melt blown pipeline heater. Firstly, let's take a look at the performance characteristics of the melt blown pipeline heater:

1. Performance characteristics of melt blown heaters

1. The melt blown heater has an advanced structure, high thermal efficiency, good mechanical strength, wear resistance, and corrosion resistance.

2. The melt blown heater can heat the air to a very high temperature, up to 450 degree , and the shell temperature is only about 50 degree .

3. The melt blown heater has high efficiency: up to 0.9 or higher.

4. Fast heating and cooling speed, up to 10 degree /s, with fast and stable adjustment. There will be no lead or lag.

5. The melt blown heater has the advantage of easy installation and disassembly.

7. The melt blown heater has clean air and a small volume.

2. Power consumption of melt blown heater, i.e. power calculation

The formula is: flow rate (kg/s) * 1.29 x 1.009 * (to be heated - initial temperature) * 1.3.

The air density is 1.29, the specific heat of the air is 1.009, the required heating degree - exceeds the starting temperature=temperature rise, and 1.3 is the safety factor.
