( 2) Special test items:
Elastic Young's modulus
Definition: The ratio of the normal stress component to the normal strain in the same phase. To determine the coefficient of material stiffness, the higher the value,
The stronger the material.
2. Proportion limit: The load can maintain a proportional relationship with the elongation within a certain range, and the large stress of the Zui is the ratio limit.
3. Elasticity limit: the large stress of the material that can be withstood without permanent deformation.
4. Elastic deformation: After the load is removed, the deformation of the material completely disappears.
5. Permanent deformation: After the load is removed, the material remains deformed.
6. Yield point: When the material is stretched, the deformation increases and the stress does not change. This point is the yield point. The yield point is divided into upper and lower yield points.
Generally, the above yield point is used as the yield point.
Yield: The load exceeds the proportional limit and is no longer proportional to the elongation. The load will drop suddenly, and then for a while,
Ups and downs, the elongation changes greatly, this phenomenon is called yielding.
7. Yield strength: the load at which the permanent elongation reaches a certain value when stretched, divided by the original area of ​​the parallel portion.
The business of the income.
8. Spring K value: the ratio of the force component to the deformation in the same phase as the deformation.
9. Effective elasticity and hysteresis loss:
On the document.write('') ​​puller document.write('') , the specimen is stretched to a certain elongation or stretched to the specified speed at a certain speed.
When the load is measured, the percentage of the ratio of the work recovered when the sample is contracted and the work consumed during the stretching is determined to be effective.
Elasticity; the percentage of the ratio of the energy lost during elongation and contraction to the work consumed during elongation, ie
Loss for lag.

Medical protective masks refer to self-priming filter dustproof medical protective equipment that can filter particles in the air, prevent the spread of certain infectious microorganisms in the respiratory tract, and block droplets, blood, body fluids, secretions, etc.
Medical protective masks are masks made of one or more fabrics that have isolation effects on viral aerosols, virus-containing liquids, and so on. Under the respiratory airflow, it still has a barrier effect on viral aerosols, virus-containing liquids, etc., and when removed, the outer surface of the mask does not contact the human body, can filter particulates in the air, and block droplets, blood, body fluids, secretions, etc. . The use of medical masks includes adhesion testing, training, model selection, medical treatment and maintenance.
Composition and function: The Medical Protective Mask consists of a mask face and a tightening belt. The mask face is divided into three layers: inner, middle and outer. The inner layer is ordinary sanitary gauze or non-woven fabric. Propylene fiber melt-blown material layer, the outer layer is non-woven fabric or ultra-thin polypropylene melt-blown material layer. This high-efficiency medical Protective Mask is highly hydrophobic and breathable, and has a significant filtering effect on tiny virus-carrying aerosols or harmful fine dust, and the overall filtering effect is good.
The medical protective mask has a good fit with the wearer's face, can filter particles in the air, block pollutants such as droplets, blood, body fluids, secretions, etc., and can filter non-oily particles by more than 95% Personal protective equipment commonly used to deal with airborne diseases.
Product specifications: According to the national standard GB 19083-2003 "Technical Requirements for Medical Protective Masks", important performances of medical protective masks include filtration efficiency, adhesion, liquid barrier performance, comfort, hygiene, and biological safety tests.
Scope of application: Medical protective masks are better protective products. It is recommended to wear when there is serious environmental pollution or sudden medical infectious diseases (such as respiratory tract infectious diseases), to prevent the spread of viruses from patients or the environment to users.
Important indicators: including non-oily particle filtration efficiency and airflow resistance.
(1) Filtration efficiency: Under the condition of air flow (85 ± 2) L / min, the filtration efficiency of aerodynamic median diameter (0.24 ± 0.06) μm sodium chloride aerosol is not less than 95%.
(2) Tightness: The overall fit factor of the mask should not be less than 100.
How to use: How to wear a head mask
(1) Gently pinch the nose clip and place the mask on the face to ensure that it can cover the nose and mouth.
(2) The upper elastic band is fastened on the head to prevent air from entering.
(3) Tighten the lower elastic band around the neck.
(4) Be sure to fully open the mask to minimize the number of layers used during breathing.
How to wear earhook masks
(1) Pass the ear straps with both hands, place the nose clip on the upper part, and wear the mask on the nose and mouth
(2) The ear strap should be placed at the base of the ear and spread from head to toe, so that the folds of the mask are fully unfolded, which helps to cover the face to the greatest extent and minimize the number of layers required for breathing.
(3) Gently pinch the nose clip to prevent air from entering.
