China Disposable Single Use Face Mask in Hospital

disposable single use face mask in hospital
Disposable medical mask
This product is composed of three materials: non-woven fabric, nose belt and elastic belt.
The mask is divided into three layers: inner, middle and outer. The inner layer is ordinary non-woven cloth.
The intermediate layer is ultrafine polypropylene blown fabric, and the outer layer is non-woven or ultrathin polypropylene blown fabric.
The ear band is made of elastic, the elastic band is made of non-woven cloth and has elastic band inside;
The nose plate is made of an aluminum roof coated with fine galvanized iron wire.
Features:
1.Non-Woven Layer

2.Filter Layer
Good Air permeability Dust prevention andSterilization
3.Non-Woven Layer
Good Air permeability Dust prevention and Sterilization
In line with YY 0469-2004 Technical Requirements for Surgical Masks, important technical indicators include filtration efficiency, bacterial filtration efficiency and respiratory resistance:

The filtration efficiency of the aerodynamics median diameter (0.24±0.06) m sodium chloride aerosol was not less than 30% under the condition of air flow rate (30±2) L/min.Bacterial filtration efficiencyThe filtration efficiency of staphylococcus aureus aerosol with average particle diameter of (3±0.3) m was not less than 95% under the specified conditionsIn the filtration efficiency flow condition, the suction resistance does not exceed 49Pa and the exhalation resistance does not exceed 29.4Pa

(specification) 17.5cm x 9.5cm
Valid for two years,
[instructionsl1. Put the mask on face of the bottom half, ears to external rope. 2. According to the bridge of the nose, in order to ensure full compliance with, pulling the mask down at the beginning of the low end of the lower jaw, and hook ear at the back of the ear on the ropes, and, finally, to ensure that the mask, completely covered face of the lower part, the largest area of protection. As stipulated in the contract of carriage of goods. Transport should be covered, in case of rain and snow: the product should be stored at room temperature, dry, well ventilated warehouse

1. Diffusion deposition: Brownian motion particles are diffused to filter fibers and adsorbed by molecular gravity.
It is easy to catch small scale particles, fine fibers and low-speed particles.
2. Interception deposition: the larger particles moving with the airflow are trapped by mechanical screening of the filtering material.
The ratio of particle diameter to filter fiber diameter affects interception efficiency.
3. Inertial deposition: when particles pass through the curved mesh channel of the filter material, they break away from the airflow and collide with the filter fiber due to inertial action, and are trapped by molecular gravity.
Large particles, high density and high speed have good interception effect.
4. Electrostatic attraction deposition: the deposition of particles caused by the electrostatic action of the filtered fiber.
