Disposable surgical masks is how to? How to disinfect?

Today is about common on the market of disposable surgical masks production processes, people concern right now is how disinfection disinfection link - factory.

A, at least three layers

If you cut masks, can see there are at least three layers of non-woven fabric, the layer is a production, at least three layers.

We see on the market are exposed at a kind of inferior masks, only 1 layer of non-woven fabric, is unscrupulous manufacturers serious jerry...

Second, what is called "non-woven"?

"Non-woven" (also called "polypropylene") is named for production process, the fabric is spinning weaving. We often wear all kinds of clothing, cotton, hemp, silk, it is a cross on the machine weft set after a bit of weaving forming.

There is a "acupuncture non-woven" similar felt needle method, we do weave, is to use N needle poke poke hook, hook together brush repeatedly to let cotton entanglements coagulation hierarchy structure, then processing into such a planar layer of fabric, it can meet the filter requirements. this is what precious materials, grandma grandpa go to what the elderly health activities, points of that kind of "environmental protection bags", most is to use "non-woven".

So why do so many days, will also face mask shortage? Because the market is in short supply... As a one-time consumables, billions of people would like to a few people every day, all of a sudden explosion in demand, coupled with the raw material supply nervous, manufacturing power emergency return to work day night work, supply also temporarily can't do it...

The three, merge three layers

Such three layers of non-woven material, is below the production machine composite together.

Notice the top left corner of the machine the trumpet? There is a cross through the bell mouth constantly to send.

Four, nose clip

The second structure: it depends on the mask mask the upper part of the root can be bent wire. Wear nose clips to knead to fixed onto the bridge of the nose, so that wearing a mask is sealed, structure , I the flat nose air leakage is more serious, sealing is tight, impact protection...

To see a close-up, along the non-woven fabric is on one side of the matching transmission wire, then below the edge structure, behind a suture, was done.

Part five, the cascade

Masks main part is below the cascade structure, open to completely cover your mouth nose, face will be afraid.

The cascade structure section so long, this will need to have a folding machine.

Is below the mechanical design, there are so three adjustable slope, small bevel set, cant make large non-woven along this several, left to right gradually narrowed the merging of "folding structure".

Then there is a link of the compressor, pressed mask surface is flat level.

Sixth, the cutting part

Single cutting hemming masks, mostly is fully automatic without manual processing. different mask is manufacturing have subtle differences, have a plenty of hemming, some direct hot-pressing glue, the small details.

Out of a single mask is the main body. Yet, there are several steps behind.

Seven, edge bonding

Below is I buy masks, look for the mask edges, each have a non-woven fabrics to enhance line pressing hanging ears, lest she was broke.

Around two big roll of non-woven fabric, waiting to reinforcing the mask edge.

One side was wrapped, then immediately pressing adhesive.

At that time out of the original has been cutting good mask, was again together, is this really affectionate spare hate since ancient times, the hate continuing have no unique period...

So you also need a cutting edge reinforcement link, make a clean break...

Eight, hot-pressing fixed rope hanging ears

Also need to use the mask edge adhesive, below this side of the mechanical paw send rope hanging ears, there is hot pressing adhesive under a rope hanging ears fixed on the mask, so a flat type of face mask even if completed.

Of course, then please out our "human quality". Masks in the news we often see factory workers to pull the ear wire test masks, some small lovely worry about sterile, rest assured, again sent to disinfection sterilization ~
