Property.What staff came into contacts with daily is exactly these medicines, chemical reagent etc., and in these chemical substances, some Nature comparisons are steady
It is fixed, but it is probably toxic and harmful to do the gas come out during some experiments, and some gases are exactly to be by breathing work
With what is damaged to human body, some toxicity is very big, such as：Cyanide etc. is all severe toxicity, and sucking to make one fatal on a small quantity, for a long time
Work under this environment, needs staff to carry out self-protection, and the use of canister respirator is solved to a certain extent
This difficult problem.Canister respirator is provided with as personal protection product, the respiratory apparatus, eyes and skin of face to staff
Effect protection, it is adaptable to endanger respiratory system but will not immediately life threatening health place, protective range include dust, weight cigarette,
Droplet, poison, poison vapor and those invisible small materials；
But, with social development, though the gas mask of various chemical experiments is regenerated constantly updating, often technology
Innovation emphasis has all been placed on the resistance to compression for strengthening mask, fire resistance, and never solves partial eye in actual use
The scientific research personnel for having myopia wears realistic problem inconvenient during mask, due to the impact sight line that can haze of wearing glasses in mask, institute
Can only select not wear glasses when using mask with many people and directly wear mask, so just will certainly hinder impact task
Chang Gaoxiao is carried out, and the gas mask filter layer of existing chemical experiment arranges less, can only filter a kind of gas of property, change
Laboratory is learned, chemical species are various, the gas of the complicated various properties of volatilizing of the property of medicine, the gas defence of existing chemical experiment
Mask just first it is unable to do what one wishes, due to the gas mask of most chemical experiment be in view of comfort level in terms of, wear
Dai Shihui feels sick or thinks that gas mask is not properly sized, and the gas mask use time of existing chemical experiment
Too long, the active carbon layer and wet gauze of the inside can be aging, and activated carbon can go bad, and the efficiency of filtration is subject to discount, or even scraps
