一、醫用口罩需求供不應求的市場格局
歲末年初，突如而來的2019-ncov給國人打了一個措手不及，導致泱泱制造大國一罩難求，由于這場瘟疫是全球性的，而防范瘟疫最有效的方式就是“戴口罩”。全球有65億人口，每人一天用一只口罩，其市場需求量是60多億只。而目前各國都表示口罩生產不能滿足人民生產生活的需求。

于是乎，我們從新聞中看到了：

比亞迪和富士康也開始制作口罩！

格力的董小姐也開始生產和賣口罩了！

……

所以導致各大口罩廠擴廠與新建的大小口罩廠

二、醫用口罩機分類

醫用口罩機可分為本體機和耳帶焊接機。

本體機也稱超聲波平面口罩機（打片機/出片機）。

耳帶焊接機可分為：超聲波內耳帶口罩機（超聲波口罩內耳帶全自動焊接機）、超聲波外耳帶口罩機（超聲波口罩外耳帶全自動焊接機）、超聲波綁帶式口罩機（超聲波綁帶口罩耳帶熔接機/超聲波綁帶口罩耳帶焊接機）這幾種不同的口罩機，生產出來的口罩分別用于醫院的不同科室。

三、開一家口罩制造廠的條件

口罩制造廠目前情況在中國分為三種類型：

第一種是作為醫療器械管理的口罩，例如：（醫用防護口罩）、（一次性普通醫用口罩）、（醫用外科口罩），現在醫用口罩主要是分為三種。生產這類產品，我們必須需要向省級食品藥品監督管理局器械處申請（醫療器械產品注冊證）、（醫療器械生產許可證），還需要1建設10萬級以上的無塵潔凈車間，并要具備一定檢驗與試驗能力（就是要購買一些實驗設備），達到一定實驗功能要求才能生產。

第二種就是勞保口罩，必須向省級技術監督局申請工業品生產許可證，并向相關部門申請“特種勞動防護用品安全標志”認證。

第三種是日常普通口罩，這種這里就不多說，因為疫是用不了這種口罩。

四、怎樣給口罩機選擇配套空壓機

生產口罩除過核心原材料外還會用到空壓機作為生產動力。那么生產口罩必不可少的空壓機也就是口罩機配套用空壓機，應如何選型？

口罩配套用的空壓機對用戶本身和空壓機設備都至關重要，空壓機選型過大浪費，空壓機選型過小可能造成空壓機長期處于加載狀態或用氣不夠或壓力打不上去等弊端。

口罩配套用的空壓機選型的步驟是：先確定工作壓力，再定相應容積流量，最后是供電容量。

1、確定工作壓力

先要確定用氣端所需要的工作壓力，加上1-2bar的余量，再選擇空壓機的壓力，當然，管路通徑的大小和轉彎點的多少也是影響壓力損失的因素，管路通徑越大且轉彎點越少，則壓力損失越小；反之，則壓力損失就越大。因此，當空壓機與各用氣端管路之間距離太遠時，應適當放大主管路的通徑。如果環境條件符合空壓機的安裝要求且工況允許的話，可在用氣端就近安裝。而對于大型的口罩生產廠家來說，精確口罩機生產匹配所需要空壓機的壓力，具體視情況而定。

2、確定相應容積流量

向用氣設備供應商了解用氣設備的容積流量參數進行口罩機配套用空壓機選型確定供電容量。在功率不變的情況下，當轉速發生變化時，容積流量和工作壓力也相應發生變化，轉速降低了，排氣也相應減少了，依此類推。

3、供電容量

供電容量能滿足所匹配驅動電機的使用功率即可。由于要滿足生產線100%生產效率，那么空壓機也得滿足24小時運行，建議選擇永磁變頻螺桿式空壓機，這種機型運行噪音低，省電節能，同比普通工頻空壓機可節能達到40%左右，具體可參照下表：

4、空壓機要求無油機還是微油機

根據口罩生產的工藝要求，如果要達到國際無油標準Class-0，建議選擇無油空壓機。這里可給朋友們推薦禾必斯特壓縮機（上海）有限公司生產的無油空壓機，物美價廉。

當然，由于無油空壓機的生產制造成本遠高于微油機，那么口罩制造商從成本角度考慮可以考慮微油空壓機，配套高效除油過濾器及除菌除臭過濾器也能達到標準。

5、口罩生產用配套空壓機還需要選擇后處理凈化設備嗎？

答案是肯定要，對口罩要求比較高的生產廠家，建議增加冷干機和精密過濾器以保證生產的產品能夠達標。

How to Choose Matching Air Compressor to Produce Surgical Mask

Introduction:

Affected by the new 2019-ncov, the surgical masks have become a necessity for people in more than 100 countries and regions in the world to produce and live. According to expert prediction, in the future, the demand for surgical masks will continue to increase, so many entrepreneurs with conscience began to invest in surgical mask production lines. But the operation industry has specialized, most people to mask machine and auxiliary air compressor because of crossing the line of knowledge is not much, often cause the choice of these equipment confusion. This article through the analysis of how to choose the air compressor and purification equipment for mask machine, we hope to provide some reference for those who need. For details, please visit www.hbm-1.com or call our professional engineers to help you out.

1. The market pattern of medical masks in short supply

At the beginning of the year, the sudden arrival of 2019-ncov caught the Chinese off guard and made it difficult for the vast manufacturing country to find a solution. As the plague is global, the most effective way to prevent it is to "wear a mask". Each of the world's 6.5 billion people USES one mask a day, with a market demand of more than 6 billion. At present, countries say that mask production can not meet the needs of people's production and life.

As a result, we can see from the news:

BYD and Foxconn are also making masks!

Dong Mingzhu of Gree Electric Appliances Inc. also began to produce and sell masks!

……

So leading to the expansion of major mask factory and the size of the new mask factory

2. Classification of surgical mask machines

Surgical mask machine can be divided into body machine and ear band welding machine.

Body machine also known as ultrasonic plane mask machine (film machine/out machine).

Ear with welding machine can be divided into: ultrasonic inner face mask machine (ultrasonic mask ear with automatic welding machine), the outer ear wearing surgical masks ultrasound machine (ultrasonic mask outer ear with automatic welding machine), ultrasonic bind type mask machine (ultrasonic mask ear bind belt welding machine/ultrasonic welding machine bind mask ear with) this several different mask machine, to produce masks used in hospitals of different departments, respectively.

3.Conditions for opening a mask factory

The current situation of mask manufacturers in China is divided into three types:

The first is the surgical mask, which is managed as a medical device, such as (medical respirator), (disposable general surgical mask), and (medical surgical mask).Production this kind of product, we must need to apply to the provincial food and drug administration devices place (medical equipment product registration certificate), (medical equipment production license), and also need 1 construction level is above 100000 dust-free clean workshop, and to have a inspection and test ability (that is, to buy some experimental equipment), reach a certain experimental functional requirements to production.

The second kind is labor protection mask, must apply for industrial product production license to provincial technical supervision bureau, and apply for "special labor protection equipment safety mark" certification to relevant departments.

The third type is the ordinary daily mask, which I won't say here, because the epidemic is not able to use this mask.

4.How to choose matching air compressor to mask machine

In addition to the production of mask core raw materials will also use air compressor as production power. So the production of masks essential air compressor is the mask machine supporting air compressor, how to choose?

The air compressor with mask matching is crucial to the user himself and the air compressor equipment, air compressor selection type is too large waste, air compressor selection type is too small may cause the air compressor in the loading state for a long time or not enough air or pressure to hit up and other disadvantages.

The procedure of air compressor selection is: first determine the working pressure, then determine the corresponding volume flow rate, and finally the power supply capacity.

⑴. Determine work pressure

Firstly, the working pressure required by the compassed air end should be determined, and then the pressure of the air compressor should be selected. Of course, the size of the pipeline and the number of turning points are also factors affecting the pressure loss. The larger the pipeline size and the smaller the turning points are, the smaller the pressure loss will be. Conversely, the greater the pressure loss. Therefore, when the distance between the air compressor and each end pipe is too far, the size of the main pipe should be enlarged appropriately. If the environmental conditions meet the installation requirements of the air compressor and the working conditions permit, it can be installed near the compressed air end. For large mask manufacturers, precise mask machine production matching the need for air compressor pressure, the specific situation.

⑵. Determine the corresponding volume flow

Learn the volume flow parameters of the gas equipment from the gas equipment supplier www.hbm-01.com.In the case of constant power, when the speed changes, the volume flow rate and working pressure also change accordingly, the speed is reduced, the exhaust is also reduced correspondingly, and so on.

⑶. Power supply capacity

The power supply capacity can meet the power of the matched driving motor. To meet the 100% production efficiency of the production line, the air compressor also needs to meet the 24-hour operation. It is suggested to choose the permanent magnet inverter screw air compressor. This type of compressor has low operating noise, saves electricity and saves energy.

⑷, Air compressor requirements oil - free or micro oil compressor

According to the technical requirements of mask production, if you want to meet the international oil-free standard Class-0, it is recommended to choose oil-free air compressor. Here we can recommend the oil-free air compressor produced by HBM Compressor (Shanghai) co., LTD. Of course, since the production cost of oil-free air compressor is much higher than that of micro oil compressor, so mask manufacturers can consider micro oil compressor from the perspective of cost, supporting high efficiency oil filter and deodorant filter can also reach the standard.

⑸. Does the supporting air compressor for mask production still need to choose the post-treatment purification equipment?

The answer is yes, to the requirements of the mask higher manufacturers, it is recommended to add cold dryer and precision filters to ensure that the production of products can meet the standards.

Through this article, I hope to be able to engage in or will be engaged in mask manufacturers friends some help.
