2021/03/22

Хэрэв бид маск өмсөхдөөчихэвч are too long or too short, we need to improve the чихэвч. If you wear it by yourself, the earhook is too long and stick to the long part with tape; or tie a knot on the чихэвч; pay attention to the size when buying, and choose the right size. What if чихэвч are purchased in large quantities? How to judge the quality of чихэвч in large quantities?

 

Sampling and testing: After purchasing in large quantities, the first thing to do is to test the чихэвч, elasticity, material, report testing, etc., don't wait for the problem when you get on the machine;

 

Үйлдвэрлэгчээс дээж илгээх, дээжийн чанарын дагуу бараа бүтээгдэхүүнийг хүлээн авахаа мартуузай;

 

Чанаргүй чанарын дараахь асуудлыг шийдвэрлэхийн тулд үйлдвэрлэгчтэй гэрээ байгуулах;

 

Be sure to choose чихэвч with good elasticity.Because of the epidemic situation, masks are worn for a long time, and the elasticity of чихэвч is very important.The чихэвч choose materials with a ratio of spandex and nylon.After continuous research and development and testing, the ratio has reached the highest suitable elasticity.
