Description
Technical field
This utility model is related to canister respirator and in particular to a kind of canister respirator filter element.
Background technology
Canister respirator is personal special type articles for labour protection, is also individual soldier protection articles for use, being worn over head can prevent due to poison
The noxious substances such as gas, dust, antibacterial, toxic and harmful or steam cause the protective equipment of human body infringement.At present, canister respirator
Mainly it is made up of parts such as filter element, cover body, eye window, expiration communicator and headbands, and filter element is gas defence face
The bodyguard that checks on of tool, the particle filterings such as dust only allow clean air to pass through.Therefore, canister respirator be widely used in oil,
Chemical industry, mine, metallurgy, military affairs, fire-fighting, rescue and relief work, health and epidemic prevention and the technical field such as scientific and technological environmental protection, machine-building.
Generally, preventing principle pressed by canister respirator, is divided into isolation type and filtering type, and impermeable gas-proof mask is mainly by mask master
Body and filter malicious part two parts composition, mask plays the effect sealing and completely cutting off extraneous air and protection mouth and nose face, in the malicious part of filter
Portion is with activated carbon as main component, and the pore surface in activated carbon, and dipping copper, silver, the metal-oxide such as chromium are so that absorption
Poison reacts, and reaches the purpose making poison lose toxicity, is mainly applicable to high concentration contamination in the air, or the height of anoxia
Empty, under water or the special occasions such as closed in space.
And the anti-dust mask that manufacturing enterprise is used mostly mainly is made up of half face shield and double filter box, had in double filter boxes
How filtering layer, constituted using inside and outside two-layer nonwoven and intermediate layer-filter cloth.Adopting polypropylene granules to be raw material non-woven fabrics, warp more
High-temperature fusion, spray webbing, paving guiding principle, hot pressing is batched continuous one-step and is produced, and is environment-friendly materials of new generation, have protection against the tide, ventilative,
The features such as pliable and tough, light weight, not combustion-supporting, easy decomposition, nontoxic nonirritant.Filter cloth is fusion spray cloth, is fine by polypropylene superfine
Dimension random distribution is bonded together, and fibre diameter can reach 0.5 ~ 1.0 micron, and the random distribution of fiber provides between fiber more
Many heat bonding chances, thus make melt-blown gas filtering material have a bigger specific surface area, higher porosity (>=75%),
So that fusion spray cloth has good filterability, shielding, thermal insulation and oil absorption, can be used for air, liquid filtration material, every
From material, receive the fields such as material, mask material.Its work principle of filter is: filtering micronic dust mainly by middle filter cloth, due to molten
Spraying has the characteristics that static electrification itself, can be with the little microgranule of adsorption volume.
But it is in the thin metallic dust below 200 mesh of low concentration or graphite dust environment, take using after 2-3 hour
Lower mask, has been covered with the dust of black at the nostril of operator；Metal powder below 200 mesh of high concentration or graphite powder ring
In border, take off mask using after 1 hour, at the nostril of operator, be covered with the dust of black.Thus illustrate, this is prevented
The absorbability of dust mask filter layer can be filled with micropore and gradually weaken, until it reaches adsorption saturation, therefore, for carrying
High dust-proof effect, frequently need to change filter element, improve production cost；Further, since the diameter of polypropylene fibre is general all
More than 0.5 micron, the tiny dust of its gap more difficult absorption particle diameter, even if its static electrification, also more difficult tens nanometers of absorption completely
Even more tiny dust, these dust directly enter alveolar by respiratory tract, can cause great damage to human body.
