By means of this outbreak, mask has now become a manpower necessary items. Whether everybody medical surgical masks, or N95 respirator, which are used in the polymer material. But before the said application material, for standard masks, halogen free flame retardant manufacturer here also understand it clearly:

Common types of masks, technical standards and the applicable scope
1. Medical surgical masks
In 2004, China's state food and drug administration issued the pharmaceutical industry standard the medical surgical masks technical requirements (YY0469-2004).
Including:
Masks must be equipped with a nose clip, nose clip can be bent by plasticity material, length > 8.0 cm;
Mask bacteria filtration efficiency should be > 95.0%, filtration efficiency should be > 30.0% of non oily grains;
Masks of inspiratory resistance should be < 49 Pa, expiratory resistance should be < 29.4 Pa;
Synthesis of 2 ml blood to 16 kPa (120 mmHg) after the lateral aspect of pressure spray to the face mask, mask side should not appear in penetration;
Masks materials should have no skin irritation reaction;
Mask the label on the outer packing should include product standards.
Qualified medical surgical masks on the outer packing should be "standards: YY0469-2004" logo.
Scope of application:
Work of the following medical surgical masks should be worn: the operating room, for aseptic operation, or immunocompromised patients nursing, prevent medical personnel will spread pathogens to patients; For body cavity puncture, there may be blood, body fluids, secretions, splash of invasive operation, such as protection of medical personnel; Personnel relatively densely populated place, such as outpatient DaoYi or consulting, elevator, emergency workers protection; Patients with respiratory tract infection [4].
2. Medical respirator
2.1 China national standards
In 2003, China's state administration of quality supervision, inspection and quarantine issued national standard the medical respirator technical requirements (GB19083-2003) [5].
Including:
Masks must be equipped with a nose clip, nose clip can be bent by plasticity material, length > 8.5 cm;
Masks particle filter efficiency of filter material should be > 95.0%;
Under the condition of gas flow is 85 L/min, the masks of inspiratory resistance < 343.2 Pa (35 mmh2o);
Synthetic blood to 10.7 kPa (80 mmHg) pressure spray to the face mask samples, there should not be a penetration mask inside;
Masks materials should have no skin irritation reaction;
Mask the label on the outer packing should include product standards.
Qualified medical respirator on the outer packing should be "standards: GB19083-2003" logo.
2.2 American standard
Environmentally friendly flame retardant manufacturer to understand to the United States institute of occupational safety and health (NIOSH) published in 1995, new type of respiratory protection standard dust, according to the classification of filter material is: N, P, R type mask three series (N class object of protection for the oily particles, R and P protective object of oily particles). Each series of masks and divided into three levels: 95.0%, 99.0%, 99.97% (i.e., 95, 99, 100), a total of nine small kind of filter material.
Recently we said to the N95 mask that is accord with standard of NIOSH, on non oily dust filtering efficiency > 95.0% of the mask. In 2003 the WHO would refer to industrial safety levels of masks us standards。

4. Protective clothing nonwoven materials
Medical protective clothing according to fabric structure can be divided into woven, nonwoven fabric and composite materials; According to the term used in the abandoned (one-time use), indefinitely and can be repeated use; According to the processing of composite technology for finishing, coating and the effect of three kinds of method.
According to its preparation technology, at present there are mainly spun-bonded, melt-blown, SMS composite technology, the water thorn and preparation technology such as flash. As people become more and more strict to the requirement of protective material, the preparation of the nonwoven protective material in toward multi-function, high performance and differentiation direction.

5. Goggles
Goggles is mainly for diagnosis and treatment, nursing procedures, may occur in patients with blood, body fluids, secretions, such as spitting; Close contact via droplets spread of infectious disease patients; Tracheotomy for patients with respiratory tract infection, endotracheal intubation and other close operation, the patient's blood, body fluids, secretions may occur when the splash.
Medical multi-purpose goggles consists of lenses and frames, frame material no special requirements. Usually in optical resin, polycarbonate (PC) or poly (methyl acrylic acid resin (acrylic) as the lens material, to prevent blu-ray, uv protection, optical radiation resistance, impact resistance and other unique optical crystal materials and exclusive special process research and development.
6. Helmets
Used for clinical medical staff in the use of hospital operating room for surgery for the patient, for the medical staff have prevent sweat, sweat absorption, and can better fixed hair, prevent hair appear when the operation, and fall.
Medical helmets (absorbent) by monolayer nonwoven commonly circle by cutting, sewing and become the aga khan; Medical helmets (protected) by SMS composite nonwovens with rubber, fastening the cutting, sewing and become.
