Dust masks belong to special labor protection equipment in China, and the national standard GB2626-2019 "Self-priming Filtering Anti-particulate Respirator" must be implemented, which divides dust masks into three levels: KN100, KN95 and KN90. For example, Baoshunan's 3216 KN100 and 3219 KN100 dust masks can achieve more protection efficiency against ultra-fine dust above microns.
The lime plant belongs to a high dust environment, in this environment, the protection of delicate dust must wear a qualified dust mask, it is recommended to use the national standard KN100 dust mask for protection.
So how to scientifically choose the right dust mask for yourself?
1) Choose a compound half-mask type: disposable masks are not suitable for long-term or occupational protection due to their high air leakage rate;
2) Choose KN100 level: high dust environment and low protection rate will lead to physical injury;
3) Choose a silicone mask, which has a relatively long service life, is soft and comfortable. Wear it for a long time, it is not easy to cause allergic reactions; Masks with high hardness are easy to cause facial indentation;
4) It is extremely important that masks come in large and small sizes. It is not recommended to buy those so-called universal models of masks, different people are tall, short, fat and thin, and have different face shapes.
5) Choose a mask with good breathability: Especially the dust mask with double filter cotton + double filter surface design, which has a longer service life and is relatively smoother to breathe.

Working in this environment, it is necessary to prevent the occurrence of pneumoconiosis.
For your health, it is recommended to do a good job of respiratory protectionFor your health, for respiratory protection, it is recommended to put health first, don't blindly be greedy for cheap, and lose health.
The scientific selection of dust masks certified by the GB2626-2006 standard helps to prevent lung damage.
1. Choose a duplex half mask type. Disposable masks are not suitable for long-term protection due to their high air leakage rate.
2. Choose KN100 dustproof filter cotton for use. Because dust is harmful to the respiratory system. It is very easy to cause pneumoconiosis. A low rate of protection will lead to physical injury.
3. It is more comfortable to choose silicone material. It is suitable for long-term wear and is not easy to cause allergic reactions. Masks with high hardness are easy to cause facial indentation;
4) It is extremely important that masks come in large and small sizes. Don't buy masks that are called generic models. Prone to air leakage.
5. There are two types of masks covering the mouth and nose, covering the mouth, nose and jaw, and it is recommended to use the latter, and this design is used in international high-comfort masks.
6. It is recommended to choose a breathing mask. Some masks are designed with double filters, and the filters are double-sided, so that the masks are relatively easy to breathe.
For the sake of good health, choose dust masks scientifically.
N95 masks work. It is one of 9 types of particulate masks certified by NIOSH. N means that it is not suitable for oily particles (the oil smoke produced by stir-frying is oily particulate matter, and the droplets produced by people talking or coughing are not oily), 95 means that the filtration efficiency reaches 95% under the detection conditions specified in the NIOSH standard. >>>More

This has some impact, although many Volkswagen cars burn engine oil, but the quality of the engine oil used is better, which can protect the engine well, even if there is a case of burning engine oil, it can also clean the carbon deposits of the engine and prolong the service life of the engine. So I've been using fully synthetic engine oil, the original fully synthetic before, after the warranty was replaced with GT Magic Red engine oil, PAO base oil, good quality, enough power, mileage is longer than the general full synthesis, although now the car has not burned engine oil, not enough insurance points are always right.
