Abstract
The invention discloses a filtration material for dust removing equipment. The filtration material comprises a high strength PTFE base cloth and a PTFE fiber net layer arranged on the upper layer of the high strength PTFE base cloth. According to the present invention, a high strength PTFE base cloth is selected so as to maintain high strength of the filtration material and greatly prolong a service life; and air permeability of the filtration material is moderate, such that emission control during a use process can be ensured.
Description
Technical field
The present invention relates to a kind of filtrate, relate in particular to a kind of cleaner and use filtrate.
Background technology
The filtrate that in cleaner, uses, one side need have high-tenacity, guarantees that filtrate has long service life, also needs moderate Air permenbility on the other hand, guarantees the emission control in the use.
Existing filtrate adopts conventional PTFE (polytetrafluoroethylene (PTFE)) base cloth, and its grammes per square metre is 130g/m
2, radially (MD) brute force is 800-900N/5 * 20cm, Air permenbility is 100L, because PTFE fiber autologous density is very big, and the fiber of very small amount often, grammes per square metre is just very high.
Along with the raising of PTFE fiber content, the brute force of filtrate is to have increased, but can make that Air permenbility descends significantly, and running resistance increases.
Therefore, develop and a kind ofly can guarantee high-tenacity, the filtrate that has moderate Air permenbility again is one of those skilled in the art's direction of being devoted to study always.
Summary of the invention
The object of the invention provides a kind of high-tenacity that both had exactly in order to address the above problem, the cleaner that has moderate Air permenbility is again used filtrate.
The objective of the invention is to realize like this:
A kind of cleaner of the present invention is used filtrate, comprises high-strength PTFE base cloth and the PTFE fiber web layer of being located at this high-strength PTFE base cloth upper strata.
Above-mentioned a kind of cleaner is used filtrate, and wherein, the grammes per square metre of said high-strength PTFE base cloth is 260g/m
2, radially powerful for 1300-1500N/5 * 20cm, Air permenbility be 100L.
The present invention selects high-strength PTFE base cloth for use, has both kept the high-tenacity of filtrate, has prolonged service life greatly, and on the other hand, the Air permenbility of filtrate is moderate, can guarantee the emission control in the use.
Description of drawings
Fig. 1 is the structural representation of cross section of the present invention.
The specific embodiment
To combine accompanying drawing below, the present invention will be described further.
See also Fig. 1, cleaner of the present invention has been shown among the figure has used filtrate, this cleaner comprises high-strength PTFE base cloth 2 and the PTFE fiber web layer 1 of being located at these high-strength PTFE base cloth 2 upper stratas with filtrate.
The high-strength PTFE base cloth 2 that the present invention selects for use, its grammes per square metre is 260g/m
2, radially powerfully compare with conventional PTFE base cloth for 1300-1500N/5 * 20cm, Air permenbility are 100L, both improved radially powerfully, prolonged service life greatly, guaranteed the Air permenbility that filtrate is moderate again, can guarantee the emission control in the use.
Above embodiment only supplies to explain the present invention's usefulness; But not limitation of the present invention; The technical staff in relevant technologies field under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification; Therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited each claim.
Claims (2)
1. a cleaner is used filtrate, it is characterized in that, said cleaner comprises high-strength PTFE base cloth and the PTFE fiber web layer of being located at this high-strength PTFE base cloth upper strata with filtrate.
2. a kind of cleaner as claimed in claim 1 is used filtrate, it is characterized in that, the grammes per square metre of said high-strength PTFE base cloth is 260g/m
2, radially powerful for 1300-1500N/5 * 20cm, Air permenbility be 100L.
