Fan also expressed his affirmation that many citizens said that the fog and haze should close their doors and windows. 4 mask, it was found that its tightness was quite good, and even the reporter was hard to tear it. No matter how small the diameter of the toner, it was locked in it and could not escape. He said that in any case, the indoor air is relatively cleaner than the polluted air outside, so it is right to close the doors and windows.

If there are patients with influenza virus in the family, they can also heat the vinegar to disinfect it. Before the experiment began, a reporter interviewed 20 citizens with masks on Bayi Avenue in Nanchang and found that 15 of them were wearing cartoon cute masks, and the Air Through Nonwoven Suppliers two were wearing one. 3 mask felt quite thick. So, among the disposable masks, ordinary absorbent gauze masks, cartoon masks and 3M masks, which mask is better able to resist the intrusion of suspended particles in the air? The mouth says nothing, the experiment is proof, this experiment will be announced for you.5. So, in their minds, what kind of masks can best resist the intrusion of airborne particles such as PM2.　　

Experimental method: In order to be able to simulate more realistically, connect one end of a long tube to a hair dryer and the other end to the mask for testing, and add the same amount of toner to each test. The boss told reporters that the people who buy such masks are mainly those who are usually exposed to dust, such as decoration workers, construction workers, etc.　　

Then, the reporter decided to choose four types of masks: disposable masks, ordinary absorbent gauze masks, general cartoon masks, and 3M masks for the experiment.　　 The sealing performance of 3M masks is higher than that of ordinary masks, so its effect of resisting dust is the best.) For this, this time The toner used in the experimental printer represents the suspended particles in the air, because most of the toner has a diameter of about 5 microns, and generally does not exceed 10 microns. It feels that it is thick enough and the gauze layer is too many.　　 Ordinary degreased gauze masks and 3M masks have good dustproof effect.

 In fact, in addition to climatic factors, pollutants such as industrial exhaust gas, automobile exhaust, dust in the air, bacteria and viruses in the air are also the 'culprits' that cause smog.5, it must be very fine and it will be difficult for people to breathe. At the same time, under the same inspection standard, the anti-haze effect of masks over 100 yuan is not necessarily better than products within 10 yuan.

However, many Airlaid Paper Company have now launched various masks with functions such as anti-fog, anti-PM2. 1 Store. Note that these two masks are not washable and cannot be reused. Sampling 29 batches of masks and testing 25 batches (4 batches can not be included in the detection range because there is no product information), none of the masks meet the national standard requirements, the minimum filtering effect is only 5%, and the highest is only 82.5 and anti-dust.　　

So, are the popular functional masks on the market really capable of preventing smog? The China Consumers Association has conducted a comparative test of the protective performance of 37 masks on the market. At present, the masks with better anti-fog and haze effect are disposable cup-shaped masks and disposable folding masks made of non-woven material with filtering effect. When you return home, you should immediately wash your face and bare skin; qualified families can install air purifiers, but pay attention to changing the filter frequently when using it. On the day of Lixia, the highest temperature in Beijing was 30℃, but the Beijing Meteorological Observatory issued a yellow haze warning signal.

This article is organized by. Haze days also have a serious impact on human cardiovascular and cerebrovascular diseases, which can impede normal blood circulation, leading to cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, and may induce angina pectoris, myocardial infarction, and heart failure. When you feel an odor in the mask or feel breathless, you should discard it and replace it with a new one.　　

Polypropylene cloth waterproof construction equipment: hammer, steel brazing, paint spatula (for mixing), plastering iron plate or bracket, 3 to 4 inch paint brush, hand sprayer, bucket, mixing board or mixing bucket . The storage stack height should not exceed the height of five coils lying flat. In fact, each waterproof geotextile is more suitable to be 20m wide after stitching. Many people say that incorrect cutting of geotextile will affect its work efficiency. Geotextile characteristics 1. So do you know what the construction machine for polypropylene fabric waterproof?

The following editor will introduce it to you in detail. Good water permeability There are gaps between the fibers, so it has good water permeability. Complete specifications: 3-Layer Face Mask Manufacturers width can reach 9 meters. 3. Corrosion resistance, long-term corrosion resistance in soil and water with different pH. There are many types of non-woven fabrics, which have been introduced to you before. One of them is geotextile. The construction is convenient, because the material is light and soft, so it is easy to transport, lay, and construction. Geotextile is divided into woven geotextile and non-woven geotextile

It is estimated that in 2016, benefiting from the demand for acceleration, and the increase in the average price partly comes from the transformation of the product structure to high-value nonwovens. Spunbond nonwovens capture some of these key applications in the past few years, but the general deterioration in uniformity over the past few years no longer participates in this market. The demand for non-woven fabrics will also benefit from automotive carpets, increasing market penetration.. The mapping can also be a valuable tool for detecting local areas in the nonwoven web non-uniformity.

The sensitivity of contour drawing and the accuracy of contour mapping of the sampling frequency and size of the test area are directly related to the size and frequency of the test area in the test development data grid. The recovery of economic growth, along with rising production output and rebound construction activities, will provide opportunities for nonwovens. With the increased uniformity of the network of emphasized points and light spots, manufacturers of spunbond nonwovens must regain the potential for some of these critical applications. In 2011, US demand is expected to expand by 3

Method 4: Sensory detection method Non-toxic non-environmentally friendly bags are milky white, translucent, or colorless and transparent, flexible, smooth to the touch, and waxy on the surface; toxic non-environmentally friendly bags are turbid or yellow in color and feel sticky. The screen printing non-woven bags are cheap and line. Hiring inexperienced workers makes the product sutures not straight or even running. Method 2:

Fire detection method Non-toxic polyethylene non-environmentally friendly bags are flammable, the flame is blue, the upper end is yellow, and burns like candle tears when burning, there is paraffin smell, less smoke; toxic polyvinyl chloride non-environmentally friendly bags are not flammable, and are extinguished when fire , The flame is yellow, the bottom is green, softening can be drawn, there is a pungent odor of hydrochloric acid. For non-woven fabric bags used by ordinary enterprises for publicity, most of them are cost-saving. To distinguish true and false non-woven bags, we first need to understand a few parameters that determine the quality of the product: 1.

The heavier the non-woven fabric used, the more natural and thicker and stronger. 3. Many manufacturers are also optimistic about the development prospects 3-Layer Face Mask Manufacturers of non-woven bags, and they have successively invested in this industry, but in the face of so many non-woven fabrics on the market Bag, how do we tell whether it is true or not? Now the editor summarizes some methods for your reference. 70 grams can bear 4-5 kg ​​weight, 80 grams can bear 5-6 kg weight, and so on. 2. The non-toxic non-environmental protection bag has a small specific gravity and can rise to the surface.

The feel is relatively thin. See the lathes of non-woven bags Everyone should know that stitching is very important in the process of non-woven bags. It is suitable for 80 grams of non-woven fabrics. Most of the non-woven bags on the market use screen printing. Look at the non-woven process A good quality non-woven bag is not only sturdy and durable, but also very good-looking, and it has a good grade in the hand.

Lily, celery, ginkgo. 2.com/. These two kinds of fruits clear heat and reduce heat, which is very suitable for people with poor throat, and kiwi can also enhance immunity and improve disease resistance!　　

Metal fume fever-The main symptom is chills after work, followed by fever, burnout, metallic taste in the mouth, nausea, itchy throat, difficulty breathing, chest pain, loss of appetite, etc. Metal elements, welding flux, and various high-temperature flames will produce various harmful substances and welding fumes, which endanger the health of workers.

As the last line of defense to protect the health of workers, individual Respiratory Spunbond nonwoven Factory protection can not only be effective, in many cases, compared with upper ventilation facilities, personal protective equipment (such as welding gas masks, dust masks).. When working in the open air, the harmful substances produced by welding will not accumulate in high concentration and are less harmful; the concentration of harmful substances will reach a very high level in high-density operations in narrow spaces or large spaces.　　Toxic gas hazard 　　 (1) Nitrogen oxides-stimulating the lungs 　

　 (2) Ozone-strongly stimulating the human respiratory tract and lungs.　　 (2) Manganese poisoning-early manifestations of fatigue, headache, dizziness, drowsiness, poor memory, and autonomic dysfunction, such as slight tremor of the tongue, eyelids, and fingers, difficulty turning and squatting.　　Respiratory protection for welders should be combined with operating characteristics. The main mode of transmission is to inhale the welding smoke into the lungs and endanger the health of workers.There are many types of harmful substances produced by welding operations. The most common occupational diseases are pneumoconiosis and metal fume fever

These three kinds of foods are mixed together to make a dish, which is a good product for nourishing the lungs, but everyone who knows that ginkgo is slightly toxic, requires boiled and peeled, and the amount is small. Rock sugar is a good medicine in Chinese medicine. Its ingredients are more effective for throat symptoms, and the side effects are very small. It enters the lung meridian, spleen meridian, moisturizes the lungs and relieves cough, but it should be noted that if you have diabetes, you must control it and not eat more. Yuzu and kiwi.1. And to mix other ingredients, such as: Sydney, white fungus, bird's nest, etc. Rock sugar.　　 4. This article is presented Here to combat smog, it is recommended to slow down and relax. It is said that food tonic is better than medicine tonic, but medicine also has good medicine
