一、醫(yī)用口罩需求供不應(yīng)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(dǎo)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(chǎn)不能滿足人民生產(chǎn)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(chǎn)和賣口罩了！

……

所以導(dǎo)致各大口罩廠擴(kuò)廠與新建的大小口罩廠

二、醫(yī)用口罩機(jī)分類

醫(yī)用口罩機(jī)可分為本體機(jī)和耳帶焊接機(jī)。

本體機(jī)也稱超聲波平面口罩機(jī)（打片機(jī)/出片機(jī)）。

耳帶焊接機(jī)可分為：超聲波內(nèi)耳帶口罩機(jī)（超聲波口罩內(nèi)耳帶全自動焊接機(jī)）、超聲波外耳帶口罩機(jī)（超聲波口罩外耳帶全自動焊接機(jī)）、超聲波綁帶式口罩機(jī)（超聲波綁帶口罩耳帶熔接機(jī)/超聲波綁帶口罩耳帶焊接機(jī)）這幾種不同的口罩機(jī)，生產(chǎn)出來的口罩分別用于醫(yī)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(yī)療器械管理的口罩，例如：（醫(yī)用防護(hù)口罩）、（一次性普通醫(yī)用口罩）、（醫(yī)用外科口罩），現(xiàn)在醫(yī)用口罩主要是分為三種。生產(chǎn)這類產(chǎn)品，我們必須需要向省級食品藥品監(jiān)督管理局器械處申請（醫(yī)療器械產(chǎn)品注冊證）、（醫(yī)療器械生產(chǎn)許可證），還需要1建設(shè)10萬級以上的無塵潔凈車間，并要具備一定檢驗與試驗?zāi)芰Γň褪且徺I一些實驗設(shè)備），達(dá)到一定實驗功能要求才能生產(chǎn)。

第二種就是勞保口罩，必須向省級技術(shù)監(jiān)督局申請工業(yè)品生產(chǎn)許可證，并向相關(guān)部門申請“特種勞動防護(hù)用品安全標(biāo)志”認(rèn)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(jī)選擇配套空壓機(jī)

生產(chǎn)口罩除過核心原材料外還會用到空壓機(jī)作為生產(chǎn)動力。那么生產(chǎn)口罩必不可少的空壓機(jī)也就是口罩機(jī)配套用空壓機(jī)，應(yīng)如何選型？

口罩配套用的空壓機(jī)對用戶本身和空壓機(jī)設(shè)備都至關(guān)重要，空壓機(jī)選型過大浪費(fèi)，空壓機(jī)選型過小可能造成空壓機(jī)長期處于加載狀態(tài)或用氣不夠或壓力打不上去等弊端。

口罩配套用的空壓機(jī)選型的步驟是：先確定工作壓力，再定相應(yīng)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(jī)的壓力，當(dāng)然，管路通徑的大小和轉(zhuǎn)彎點的多少也是影響壓力損失的因素，管路通徑越大且轉(zhuǎn)彎點越少，則壓力損失越??；反之，則壓力損失就越大。因此，當(dāng)空壓機(jī)與各用氣端管路之間距離太遠(yuǎn)時，應(yīng)適當(dāng)放大主管路的通徑。如果環(huán)境條件符合空壓機(jī)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(chǎn)廠家來說，精確口罩機(jī)生產(chǎn)匹配所需要空壓機(jī)的壓力，具體視情況而定。

2、確定相應(yīng)容積流量

向用氣設(shè)備供應(yīng)商了解用氣設(shè)備的容積流量參數(shù)進(jìn)行口罩機(jī)配套用空壓機(jī)選型確定供電容量。在功率不變的情況下，當(dāng)轉(zhuǎn)速發(fā)生變化時，容積流量和工作壓力也相應(yīng)發(fā)生變化，轉(zhuǎn)速降低了，排氣也相應(yīng)減少了，依此類推。

3、供電容量

供電容量能滿足所匹配驅(qū)動電機(jī)的使用功率即可。由于要滿足生產(chǎn)線100%生產(chǎn)效率，那么空壓機(jī)也得滿足24小時運(yùn)行，建議選擇永磁變頻螺桿式空壓機(jī)，這種機(jī)型運(yùn)行噪音低，省電節(jié)能，同比普通工頻空壓機(jī)可節(jié)能達(dá)到40%左右，具體可參照下表：

4、空壓機(jī)要求無油機(jī)還是微油機(jī)

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

當(dāng)然，由于無油空壓機(jī)的生產(chǎn)制造成本遠(yuǎn)高于微油機(jī)，那么口罩制造商從成本角度考慮可以考慮微油空壓機(jī)，配套高效除油過濾器及除菌除臭過濾器也能達(dá)到標(biāo)準(zhǔn)。

5、口罩生產(chǎn)用配套空壓機(jī)還需要選擇后處理凈化設(shè)備嗎？

答案是肯定要，對口罩要求比較高的生產(chǎn)廠家，建議增加冷干機(jī)和精密過濾器以保證生產(chǎn)的產(chǎn)品能夠達(dá)標(biāo)。

通過本文，希望能夠給從事或即將從事口罩生產(chǎn)制造商朋友一些幫助。如需進(jìn)一步了解，可隨時致電13918092363（孫工）13916285293（董工），我們的工程師將耐心為您服務(wù)！

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.

Permanent magnet frequency conversion Energy-saving table

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.

For further information, please feel free to call 13918092363 (Mr. Sun) 13916285293 (Mr. Dong), our engineers will be patient to serve you!
