Abstract
The utility model relates to membrane filter material cloth for industrial dust filtration, which comprises non-woven fiber webs and a fabric layer. The utility model is characterized in that the non-woven fiber webs have two or more layers, the fabric layer is a glass fiber web which is positioned between two layers of the non-woven fiber webs, and the outer side of one layer of the non-woven fiber webs is coated with a polytetrafluoroethene (PTFE) air permeation filter membrane. Because one layer of glass fiber web is arranged between two layers of the non-woven fiber webs and the PTFE air permeation filter membrane is coated on the surface layer of the non-woven fiber webs, the utility model has the characteristics of strong air permeability, corrosion resistance, water resistance, long service life of materials, etc.
Description
Technical field
The utility model relates to multiple subsides nonwoven, especially relates to the Membrane filter material cloth that a kind of industrial sector filter dirt filter gas is used.
Background technology
Products such as cement furnace, chemical industry, pharmacy form a large amount of dust in the process of giving birth to, along with waste gas enters atmosphere, this dust brings pollution to environment, also cause simultaneously the wasting of resources, effectively one of dust collection method is to adopt bag-type dust, it had both played dust removing effects, had reached the effect of reclaiming again, made the former utilization again of money.But contain sulphur or compositions such as acid, alkali in some waste gas,, cause corrosion, shortened the cloth bag life cycle, the nonwoven of employing is also arranged as raw material, because etches such as moisture influence service life to cloth bag if use the cloth bag filter dirt of prior art.
Summary of the invention
The utility model mainly is to solve the employed filter dirt of prior art cloth bag, and corrosion resistance or resistance to water are relatively poor, and service life is short, the technical problem of grade that Air permenbility is not good enough.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: contain nonwoven web and tissue layer, it is characterized in that described nonwoven web has two layers or more, described tissue layer is a glass fiber mesh, glass fiber mesh also pastes a skim again above the nonwoven web between two layers of nonwoven web.
As preferably, described film is the ventilative filter membrane of polytetrafluoroethylene (PTFE).
Because the utility model is provided with the layer of glass net in the middle of two layers of nonwoven web, the nonwoven web surface layer also has the polytetrafluoroethylene (PTFE) filter membrane of breathing freely, thereby the compound ventilative Membrane filter material cloth of height that becomes, make it have antiacid, alkali resistant, anti-sulphur, moisture-resistant, high ventilative, and filtering traffic is big, the filtering accuracy height, long service life etc. are characteristic significantly.
Description of drawings
Accompanying drawing is the cross section structure schematic diagram of embodiment;
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.As shown in the figure, in the middle of two layers of nonwoven web 2, layer of glass net 3 is arranged, on nonwoven web 2, paste the ventilative filter membrane 1 of one deck polytetrafluoroethylene (PTFE) again.Its production process is that non-woven fibre forms nonwoven web 2 after opening silk floss, mixing, combing, and is multiple with glass fibre 2 on the nonwoven web 2 of bottom, again the nonwoven web 1 on superimposed upper strata, the online then water thorn that carries out, roll is dried, form non-woven fabrics base material, rolling.Then on the multiple film production line with polytetrafluoroethylene (PTFE) on the non-woven fabrics base material after ventilative filter membrane 1 is attached to uncoiling again, rolling after the drying forms final products.The product of present embodiment after tested, its every square metre Air permenbility reaches 4-10m
3/ s is specially adapted to filter the waste gas cloth and the agricultural good harvest cloth that have soda acid, oil smoke and dust in environment-friendly processing unit.
Claims (2)
1 one kinds of Membrane filter material cloths, contain nonwoven web and tissue layer, it is characterized in that: described nonwoven web (2) is two layers or more, described tissue layer is glass fiber mesh (3), glass fiber mesh (3) is positioned between two layers of nonwoven web (2), also pastes a skim (1) on nonwoven web again.
