Description
Technical field
The utility model is related to a kind of personal protection equipments, and in particular to a kind of flexible demifacet type chemical experiment gas defence face
Cover.
Background technology
Laboratory, especially chemical laboratory, chemical species are various, and pharmacological property is complicated, most of to have certain poison
Property.What staff came into contacts with daily is exactly these drugs, chemical reagent etc., some Nature comparisons are steady in these chemical substances
The gas come out when determining, but doing certain experiments may be toxic and harmful gas, some gases are exactly to pass through respiration
Human body is damaged, some toxicity is very big, such as：Cyanide etc. is all severe toxicity, and sucking will make one fatal, permanent worker on a small quantity
Make under this environment, staff to be needed to carry out self-protection, and the use of breathing mask solves this to a certain extent
One problem.Breathing mask provides the respiratory apparatus, eyes and skin of face of staff effective as personal protection product
Protection, suitable for endangering the place of respiratory system but not the health of life threatening immediately, protective range includes dust, weight cigarette, mist
Drop, poison gas, poison vapor and those invisible small substances.
But with social development, though the gas mask of various chemical experiments is regenerated constantly updating, often skill
The innovation emphasis of art has all been placed on the resistance to compression of enhancing mask, fire resistance, and never solves part in actual use
Eyes have the scientific research personnel of myopia to wear realistic problem inconvenient when mask, and due to wearing glasses in mask, the influence that can haze regards
Line will certainly hinder to influence to appoint in this way so many people can only select not wear glasses and directly wear mask when using mask
The gas mask filter layer setting of the normally and efficiently progress of business, existing chemical experiment is less, can only filter a kind of property
Gas, chemical laboratory, chemical species are various, and pharmacological property complexity can volatilize the gas of a variety of properties, existing chemical experiment
Gas mask just first it is unable to do what one wishes, due to most chemical experiment gas mask be in view of comfort level side
Face can feel sick when wearing or think that gas mask is off size suitable, and the gas mask of existing chemical experiment
Usage time too long, the active carbon layer and wet gauze of the inside can aging, and activated carbon can go bad, the efficiency of filtering by discount,
It even scraps and can not reuse, therefore scientific research personnel can be threatened by toxic gas.
