Description
Technical field
The utility model relates to a kind of personal protection equipments, and in particular to a kind of novel filter of chemical experiment breathing mask
Malicious box.
Background technique
Laboratory, especially chemical laboratory, chemical species multiplicity, 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, and some gases are exactly to pass through respiration
It causing harm to the human body, some toxicity is very big, such as: cyanide 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 being kept 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
The realistic problem that eyes have the scientific research personnel of myopia inconvenient when wearing mask, due to the influence view that can haze of wearing glasses in mask
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 multiplicity, 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
Too long using the time, the active carbon layer and wet gauze of the inside can aging, and active carbon can go bad, the efficiency of filtering by discount,
It even scraps and can not reuse, therefore scientific research personnel will receive the threat of toxic gas.
The Chinese utility model patent of Publication No. CN204502593U discloses a kind of malicious box of activated carbon fibre filter,
