Disposable mask quality control inspection service

Inspection items of various face masks quality inspection: filter efficiency test, quality test, tightness, air tightness, active carbon component test, microorganism test, ethylene oxide residue, dust resistance efficiency, filter element test, etc.

From August 1, 2009, gb2626-2006 respiratory protective equipment self-priming filter type particle respirator was implemented, which stipulated that the protection levels for particles were Kn90, kn95 and kn100. The protection levels of oil particles are kp90, kp95 and kp100. The filtration efficiency was 90%, 95% and 99.97% respectively. Kn100 and kp100 are of high protection level. According to the national gb2626-2006 standard, the filter elements of dust masks shall be printed with permanent identification: “gb2626-2006-kn100” national standard, year number and protection grade identification. The higher the degree of protection and filtering efficiency, the higher the safety of the dust mask.

Protection performance for fine particles (PM2.5) The protection effect level is set according to the air quality category in the national air quality standard. The protection effect level is divided into four levels from low to high: Level D, level C, level B and level a. the corresponding use environment is as follows: Level D is suitable for moderate (PM2.5 concentration no more than 150 μ g / m3) and below pollution, level C is suitable for severe (PM2.5 concentration no more than 250 μ g / m3) and below pollution, and level B is suitable for severe pollution Dye (PM2.5 concentration no more than 350 μ g / m3) and grade A are used when PM2.5 concentration reaches 500 μ g / m3. Wear mask reasonably according to the standard requirements, which can reduce the concentration of PM2.5 inhaled to less than 75 μ g / m3, and make the air quality in the inhaled body reach good or above level.

Coronavirus Impact on Manufacturing from China

Unless you are living under a rock, you may have heard about the coronavirus originated in Wuhan, China. The Hubei province, and much of China, is in complete lockdown with many businesses closed, and people staying home as the government extended Chinese New Year for a few days until the epidemic is under control.

This should obviously have an economic impact, at least in the short term, for the next few weeks or months since people are asked to stay home, and a lot of goods consumed is manufactured in China. And indeed, some companies are announcing delays due to the virus.

Coronavirus-manufacturing-china

It’s difficult to find updates of delivery time from companies actually based in China, potentially because they need to check with their sub-suppliers to check whether they are affected by the virus or not. But I’d assume if you have purchased products from Aliexpress, GearBest, GeekBuying, and the likes, and if the parcel has not left China yet, you won’t get it anytime soon unless there are stock at the suppliers’ warehosue. By the way, the virus needs a carrier (e.g. living creature) to stay alive, so there’s no risk to get infected with the coronavirus from a package since it takes several weeks to arrive at its destination.

So far by Feb 1st,2020, Chinese government has officially extended the Lunar Spring Festival to Feb 10th,2020. And only some important retailed shops, foods market, logitic company, mask factories etc are allowed to run first. As I witness, some Chinese companies will have their employee work at home for the week of Feb 3 to Feb 7th, so I believe they will update you the situations when you talk to them if you buy from them.

So beside the human toll, there will be an economic impact, but only time will tell just how much this impact will be.

KN95 mask, N95 mask, surgical mask, surgical mask FFP2, etc. What is the difference

On market, there are so many kinds of masks, how do we distinguish and how to choose?

There are two main categories: one is medical masks, one is civilian masks. Medical surgical mask, medical protective mask, N95, FFP2 can be used for protection in medical institutions, KN95 can not be used in medical institutions, but the general public can choose by themselves.What is the difference?

1. Medical: disposable surgical mask (medical nursing mask)

Disposable surgical masks masks, surgical masks, medical care, general standards: YY0969, also has a lot of their own design for the enterprise production, usually cannot guarantee the filterability of pathogenic microorganisms, dust, commonly used in conventional nursing care in the hospital, main effect is barrier between medical staff and patients daily cross contamination, no particular high demand. If used by the general public, that is, to stop bad breath, pretend, the actual effect of protection is not very ideal.

KN95 mask, N95 mask, surgical mask, surgical mask FFP2, etc. What is the difference

2. Medical: medical surgical mask: yy0469-2011

Medical surgical mask must refer to the medical standard yy0469-2011 for production. If the enterprise sets its own enterprise standard to meet or even higher than the requirements of YY0469, it can also be printed on the mask packaging (therefore, it is not necessary to have YY0469 to be qualified, specific or to see the name of the mask and enterprise standard to identify); Surgical masks are mainly used for invasive operations such as surgery and catheterization in hospitals.

YY0469 has bacteria filtration performance requirements to the surgical masks, general filtration efficiency of non oily grains should reach more than 30%, filtering efficiency to achieve more than 95% of bacteria (note, here is not the meaning of N95, don’t be confused with medical respirator), in addition, medical surgical masks have requirement for synthetic blood penetrating (can be as simple as anti permeability), enterprise production. The masks are generally divided into three layers: the internal water absorbing layer, middle filter layer, waterproof layer outside, each layer has a special role.

3. Medical: medical protective mask

Medical protective mask, next is disposable medical nursing mask, also known as medical protective mask, in line with gb19083-2003 standard, the important technical indicators include non-oily particle filtration efficiency and airflow resistance. For diameter (0.24 ± 0.06), the filtration efficiency of sodium oxide aerosol of m is not less than 95%, that is, N95 and above. Inspiratory resistance should not exceed 343.2pa.

4. Civil use: KN mask: gb2626-2006/2019

KN95 mask, N95 mask, surgical mask, surgical mask FFP2, etc. What is the difference

Because of the different place to work, people come into contact with the particles generally can be divided into two categories, oily and not oily, “KN” type of face mask is mainly used for protection of oily particles masks, and type “KP” masks can be protective oil particles can also be protective of oily particles, such as chemical industry contact for more oily particles (such as paraffin oil steam), generally use KP type mask. Other industries include ordinary civilian use, with KN masks mainly (of course, there are some civilian smog masks can use KP masks).

According to GB2626 standard requirements, KN type mask, according to its filtering performance of non-oily particles for re-classification, there are also familiar with KN90, KN95, KN100 three masks. Among them, KN95 mask is one of the most common masks with a filtration performance of over 95% for non-oily particulate matter (detected by sodium chloride).

See here, don’t know if you have found a problem, just the front, have to tell everyone about medical surgical masks (YY0469-2011) for non-oily filterability of particulate matter for 30% or more, the less than 95% or higher requirement in KN95 mask a lot, so a lot of people naturally think that KN type mask, especially the type KN95 masks, definitely better than the effect of medical surgical masks! Is that absolute?

Surgical masks have impermeable requirements, generally divided into three layers, the outermost layer for the waterproof layer, the most important reason to use masks in the medical environment is to isolate bacteria, and bacteria once attached to the surface of the mask, it is very easy to follow the moist mask directly into the mask, so, impermeable is very important!

And throughout the whole GB2626, there is no standard requirements for KN mask waterproof, not only KN mask, KP mask is not, that is to say, meet all the standards of GB2626 qualified masks, there is no anti-penetration requirements. At this point, KN masks are not as good as surgical masks!

FAQ 1: Is a breathing valve good or bad?

KN95 mask, N95 mask, surgical mask, surgical mask FFP2, etc. What is the difference

Because of wearing a mask of doctors and patients, all can’t promise you must be healthy, don’t (incubation period with infectious) with the virus, and masks airflow with exhalation valve is a one-way only protection, is not good to cut off the route of transmission, from the outbreak control perspective, the two-way protection is the right way, so don’t recommend this type of face mask.

FAQ 2: About the safety mask standard: gb19083-2010 and GB2626 which is good?

Misunderstanding: China’s GB19083 standard does not have “N95”, but the use of “level 1”, “level 2” and “level 3” to express the filter efficiency level, generally level 1 can meet the “N95/KN95” requirements. That is to say, as long as any “medical respirator” that conforms to GB19083 standard, the filtration efficiency of N95 and KN95 has been achieved absolutely.

Difference: GB19083 is the highest standard of medical execution, this is the standard of medical execution, this kind of mask you will find that there is no breathing valve, and are used in the medical scene, of course, if you buy it can also be outside civilian use.

GB2626 is usually used for civilian masks, mainly used as some protection such as painting, welding, industrial and haze and other non-medical scenarios of protection, such as the most common 3M brand KN95 masks is this type!

In addition, like the medical surgical mask of yy0469-2011, GB19083 also puts forward the requirements of “synthetic blood penetration”, and there is also a parameter requirement of “surface wetting resistance”, which makes clear the protective effect of the medical protective mask on blood and fluid, which is not in GB2626 (KN type). See the difference? There is no anti – flying liquid spillage for civil use.

How to Wear N95 Masks Properly

1. Cup the respirator in your hand with the nosepiece right-side up, and the headbands hanging freely.

2. Position the respirator under your chin and the nosepiece on the bridge of your nose.

3. While holding the respirator in position, pull the TOP headband over your head and rest it at the crown of the back of your head.

4. As you continue to hold the respirator in position, pull the BOTTOM headband over your head and rest around your upper neck, below your ears.

5. Position the respirator under your chin and the nosepiece on the bridge of your nose.

6. (Applies to 536N95C & 511N95S Only) Using both hands, mold the malleable nosepiece to fit snugly against the nose bridge and face below the eyes.

7. Using a mirror, further check and adjust edges to provide a good seal on the face.

Ways To Improve Your Import Benefits

Work With A Government-regulated Trading Program

Ghana, Ivory Coast, and many other countries have strict regulations that include regulating trade between African farmers and exporters in their country and the outside world. While such programs may seem restrictive or overbearing, they have many benefits for foreign importers including reduced risk when trading with a government-approved firm. To increase security, when at all possible, participate in government-sanctioned trade programs. In fact, in some cases, it may be illegal to trade outside of these programs.

Analyze Supply Chain

Alliances form, trade embargoes dissolve, and countries adopt new practices—all reasons why it’s valuable to review your supply chain from time to time. Dedicate some time periodically to discussing new and favorable trade agreements that may reduce or eliminate taxes, new trade agreements between your country and countries where your target product is manufactured or grown. Also look for ways to cut costs in your operation through efficient ordering and transport practices.

Obtain A Third-party Risk Assessment

Hire a third-party compliance consultant or firm to assess risk and evaluate your import/logistics. While it may also be beneficial to have an in-house staff member dedicated to compliance, familiarity with the operation over time makes it easy to miss potential threats. Hiring an experienced, outside adviser will doubtless prove beneficial. At best alert you to potential risks before they arise, and at least provide you with alternative points of view to tighten your logistics and secure your import operations.

Join A Local Trade Association

Joining a local trade organization either in the country where you operate, or the country where you import can significantly increase your import benefits by providing news, security tips, and general information about foreign trade. Joining a local trade organization can be a great way to secure new business and also gain and trusted suppliers and referrals from other contacts.

Invest In Good Software

When participating in international trade, working with different cultures, currencies, laws, and languages can make staying on top of payments, customs regulations and guidelines, and other deadlines very taxing. It’s essential to invest in a good software program or several programs to manage invoicing, accounting, and payments, as well as document deadlines and communications with customs officials and business partners to ensure that nothing falls through the cracks.

Set A Goal

One of the best ways to improve your business and achieve success is to set a goal. You may set a goal to reduce your import costs by a certain percentage or to increase the amount you import without increasing your budget. Many companies fear to set a goal, or worse, don’t bother because outside factors may reduce or eliminate the chance of achieving your goal, especially in the import and export business. Even if you don’t quite reach your goal, setting a goal provides a great way to evaluate business practices and create strategies to reduce trade barriers in the future.

Increase Your Order Quantity

Bulk ordering reduces costs associated with repeated transactions including payment, shipping, and customs charges. After developing trust and rapport with a buyer, consider renegotiating to import more products at a reduced cost per product. To make the deal equally beneficial for the buyer, offering advance payment or other favorable terms may increase your likelihood of securing a better deal. Bulk ordering products off-season can also reduce rates by eliminating the need to order products during times of year when demand is high, and the product is sold at a higher price. It’s more cost effective to make a few large orders than frequent small orders.

Develop A Niche

You may import only one product, but certain forms of the product may sell better than another. Compare the costliest products to import based on cost per product, customs, and shipping fees, compared with your most profitable products based on highest demand. Look for opportunities to eliminate products that are costly and low-volume sellers. Focus in on the products that are cheapest to obtain and bring in the highest revenue. It’s important to look at data over the year, as prices fluctuate throughout the year and may also change over time as global supply and demand vary.

Research Local Area To Understand Potential Concerns

Before engaging in trade with a local supplier, research the local area to identify concerns. In some parts of Africa, landlocked countries face long delays transporting products on unpaved roads, which can reduce the shelf life of perishable products. Research the local area to identify concerns and find ways to mitigate concerns before engaging in trade.

Establish Clear Written Expectations

Writing details of your trade agreement clearly and openly will reduce the likelihood of a dispute, and provide a clear way to evaluate terms in the unfortunate event that you encounter conflict. Even in long-standing relationships, it will be helpful to develop an agreement in writing if you don’t have one already. Any time new procedures or processes are outlined in email communication or other conversation, consider adding a formal addendum to your written contract or agreement to be signed by both parties.

 

The Benefits Of Importing

Extend your profit margins

A key reason that companies all over the world choose to import goods is to extend their profit margin. High taxes, wage minimums, and material costs in certain countries make it more useful to import products from a country where fees, wages, and material costs are considerably lower. Certain products can cost upwards of 50% less to grow, manufacture or produce abroad. This situation is particularly common when importing goods where natural resources are abundant. For example, imported cacao from Ghana is considerably cheaper than imported cacao from the United States.

Better Quality

Sometimes you’d like to sell an item or good that is not native to your region. In this case, it’s better to go the source, as you’re likely to get a higher quality product. Each country has particulars strengths when it comes to exports. Consider, the Moroccan sardine industry, for example. Sardines from Morocco are not only plentiful but considered much better quality due to the soil and natural habit that make the country an ideal home for the fish. When possible, it’s best to get your product from the highest quality source, even if that means importing out of the country.

Government-Assisted Trade

In many countries, such as Ghana and Ivory Coast, the government plays some part in managing trade between local farmers and importers. Not only does this minimize risk, but in some cases, the government provides added support and benefits to importers including reduced taxes and assistance with customs. In these cases, it is very advantageous for companies to develop relationships with foreign exporters.
