Masks of raw materials is the core of non-woven filter bacteria is currently the leading enterprises in TEDA clean nonwoven day capacity maximum is 10 tons (some say 10 tons [1], one that seven tons [2]) per ton can produce 700,000 masks, that one day the highest capacity can only produce 7 million . But the expansion of the production line period a year [2], that is to say the moment there is no way to expand business capacity.
At present, I searched for a similar non-woven production enterprises: TEDA 10 tons, shaped filter, Yi Mao filter 4.2 tons, China non-woven industry. Behind the figures are given some reports online, it does not mean I did not see. We assume that the average company's production capacity of 5 tons per day, there are 10 such companies, then that kind of national non-woven fabric production capacity is 50 tons per ton of production estimated 700,000 masks, that is, every day supply up to 35 million mask production.
The production of such non-woven masks of raw fiber material is a high melt index, reported in the current national production 880,000 tons in 2019, is said to supply 250,000 tonne masks [3], that means the daily high melting fiber material can supply of 880,000 tons / 365 * 250 000 / ton to about 600 million .
In summary estimate, we produce every day can be in 35 million , while the Minister of Industry and Miao Wei said, "Our masks maximum production capacity is more than 2000 million a day," it is believed bottleneck may be in the non-woven processing, but it is difficult to improve produce. . .
If we assume that the thesis according to the number of patients is estimated, assuming 20,000 patients, nursing staff needed to close one person each patient, each mask can hold four hours (that is to say a person stick to one day jobs to be six masks ), so also it is the daily consumption of 120 000 , if you count other health care workers, health care workers assume that each potential exposure of the patient 10, will be a day to 1.2 million .
If you count the little brother takeaway, shop, bus drivers, sanitation workers and that greater demand! Suppose a city 500 bus lines, each line 10 master, one day a mask, a mask is necessary to 5000, even if each province has two major cities, that have 10 000, 4 million takeaway little brother, one day a going 4 million . . .
On the other hand if the average person masks changed once every five days, and 30 million for 150 million people, but only 20 million for 100 million people can use , not enough 1.4 billion Chinese people a hand.
The most annoying is that according to reports, even if the export to domestic sales of protective clothing, protective clothing production capacity will total 30,000 / day +5 Wan / day is still less than the front-line 100,000 / day needs [4]. . . . . .
I can only advise you to stay at home really is good, less walking, to extend the service life of the hands of the mask, so the mask is supplied to where they are most needed.
