Abstract
The utility model discloses high-temperature-resistant spunlaced filtering felt made of polytetrafluoroethylene fiber. On the upper surface and the lower surface of a polytetrafluoroethylene fiber fabric, polytetrafluoroethylene fiber layers are symmetrically jetted and adhered by high-pressure water. The high-temperature-resistant spunlaced filtering felt has the advantages of good thermal stability, chemical stability and insulation; the high-temperature-resistant spunlaced filtering felt has good water resistance, so that the hydrolysis is fundamentally avoided; the high-temperature-resistant spunlaced filtering felt can resist the temperature as high as 2600 DEG C; the strength of the high-temperature-resistant spunlaced filtering felt is 20 percent higher than that of the needled felt; the high-temperature-resistant spunlaced filtering felt has good filtering efficiency and dust-cleaning performance; and the high-temperature-resistant spunlaced filtering felt can be used for a longer time under the same working condition.
Description
Technical field
The utility model relates to a kind of filtering material that is used for flue gas and treating flour dust, particularly a kind of polytetrafluoroethylene fibre high-temperature resistant water thorn filter felt.
Background technology
Polytetrafluoroethylene fibre PTFE is commonly called as " plastics king ", 100%PTFE filtering material by needling process production, be subjected to strong acid, alkali corrosion hardly, heatproof can reach 260 ℃ (300 ℃ of moments) and have anti-oxidant, anti-hydrolysis, hydrophobic, refuse characteristics such as oil and easy-to-clean ash, be the optimum Match filtrate of waste incineration deduster.But, because that the PTFE fiber has a static load is big, self glutinous cunning, characteristics such as natural crimpness is little, cohesive force is little, spinnability difference, this gives and produces PTFE fiber filter felt and brought difficulty.
The utility model content
Technical problem to be solved in the utility model is that a kind of Heat stability is good, chemical stability is good, filter efficiency is high polytetrafluoroethylene fibre high-temperature resistant water thorn filter felt will be provided.
In order to solve above technical problem, the utility model provides a kind of polytetrafluoroethylene fibre high-temperature resistant water thorn filter felt, is the upper and lower surface at the polytetrafluoroethylene fibre base cloth, injects with High-Pressure Water symmetrically and pastes the polytetrafluoroethylene fibre layer.
Described polytetrafluoroethylene fibre base cloth is the fabric that adopts the plain weave weave to make with the polytetrafluoroethylene fibre yarn.
Superior effect of the present utility model is: good heat endurance, chemical stability, insulating properties; Hydrolysis can not take place in good water-resistance; Heatproof can reach 260
0C(moment 300
0C); Powerful than Nomex raising 20%; Have good filter efficiency and deashing property, long service life under equal working condition.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The number in the figure explanation
1-polytetrafluoroethylene fibre base cloth; 2-polytetrafluoroethylene fibre layer.
The specific embodiment
See also shown in the accompanying drawing, the utility model will be further described.
As described in Figure 1, the utility model provides a kind of polytetrafluoroethylene fibre high-temperature resistant water thorn filter felt, is the upper and lower surface at polytetrafluoroethylene fibre base cloth 1, injects with High-Pressure Water symmetrically and pastes polytetrafluoroethylene fibre layer 2.
Described polytetrafluoroethylene fibre base cloth is the fabric that adopts the plain weave weave to make with the polytetrafluoroethylene fibre yarn.
Manufacture craft process of the present utility model is: fiber is fed to opener by griping cotton machine, opener with the abundant shredding of fiber after the feeding carding machine in, after the abundant combing of cylinder of rotation at a high speed, because the effect of inertia and the tangential air blast of cylinder, the PTFE fiber is blown is attached to defeated lace curtaining, fiber is because the effect of the negative pressure on the defeated lace curtaining, condensed upon firmly on the defeated lace curtaining, fiber is sent to by defeated lace curtaining and carries out pre-needling in the pre-needling machine, PTFE fleece therebetween one deck PTFE base cloth after the two-layer pre-needling delivered to carry out water thorn in the spun-laced machine, the finished product that last drying machine oven dry is made.
The utility model drops into actual operating mode and uses, and through implementing proof, continuous operation temperature of the present utility model is 260
0C, moment serviceability temperature be 300
0C, brute force 〉=700N/5 * 20 ㎝ radially, broadwise brute force 〉=700N/5 * 20 ㎝, radial fragmentation percentage elongation≤30%, broadwise elongation at break≤55%, air permeability 8～10m
3/ m
2Min has improved 1～3 year service life.
