Abstract
The invention relates to a polytetrafluoroethylene glass fiber backerboard. The polytetrafluoroethylene glass fiber backerboard which comprises a scaleboard body is characterized in that: the scaleboard body comprises a polytetrafluoroethylene scaleboard and a glass fiber woven cloth layer, and the back of the polytetrafluoroethylene scaleboard and the glass fiber woven cloth layer are compounded into one body by undergoing high temperature and high pressure hot melting. The polytetrafluoroethylene scaleboard has a thickness of 1.5-5mm and a width of 1.5m, and the glass fiber woven cloth layer is processed from a glass fiber with the diameter of 3-5mum. The polytetrafluoroethylene glass fiber backerboard of the invention which has excellent low temperature resistance, corrosion resistance and weatherability and good mechanical properties can be used as inner scaleboards of chimneys to protect the inner scaleboards of the chimneys from contacting and corroding of industrial fuel tail gases containing a large amount of corrosive sulfides and the like, so the service life of the chimneys is substantially prolonged. So the polytetrafluoroethylene glass fiber backerboard of the present invention is suitable for being treated as inner scaleboards of chimneys.
Description
Technical field:
The present invention relates to a kind of polytetrafluoroethylene (PTFE) liner plate, particularly relate to a kind of polytetrafluoroethylene (PTFE) glass fibre backer board.
Background technology:
The tail gas of industrial fuel is usually through smoke stack emission, mostly contains a large amount of corrosivity sulfuration thing etc. in the tail gas of industrial fuel, and the chimney that originally promptly uses the titanium alloy of import to make is also because of Long contact time H
2SO
3, H
2SO
4Etc. caustic acid, particularly when temperature surpasses 100 ℃, corrode more serious because long contact corrosion sulfide causes infiltrating in the capillary this sulfide, make chimney produce the crack, the reparation that needs repairing, however the chimney height that this titanium alloy material is made is generally at 120-200m, thereby make that when keeping in repair, relatively difficulty and the bigger problem of maintenance cost are welded in existence.In addition, this titanium alloy nearly all is from external import, and price is very expensive, and actual useful year also is about one to two year.For this reason, await solving service life of chimney of the corrosivity exhaust emissions of industrial fuel.
Summary of the invention:
The objective of the invention is to provide a kind of polytetrafluoroethylene (PTFE) glass fibre backer board, be significantly improved service life of chimney that it not only can be used in the corrosivity exhaust emissions of industrial fuel effectively, and, greatly reduce manufacturing cost and use cost.
Solution of the present invention to achieve the above object is: polytetrafluoroethylene (PTFE) glass fibre backer board of the present invention comprises the liner plate body, described liner plate body is formed by polytetrafluoroethylene (PTFE) liner plate and the woven layer of cloth of glass fibre, and the back side of described polytetrafluoroethylene (PTFE) liner plate and the woven layer of cloth of described glass fibre compound through the HTHP hot melt be one.
The thickness of described polytetrafluoroethylene (PTFE) liner plate is that 1.5-5mm, width are 1.5m.
The woven layer of cloth of described glass fibre is that the glass fibre of 3-5 μ m processes by woven by diameter.
The present invention has released a kind of polytetrafluoroethylene (PTFE) glass fibre backer board, it is formed by described polytetrafluoroethylene (PTFE) liner plate and the woven layer of cloth of described glass fibre, and the back side of described polytetrafluoroethylene (PTFE) liner plate and the woven layer of cloth of described glass fibre compound through the HTHP hot melt be one.
The polytetrafluoroethylene (PTFE) liner plate is made by polytetrafluoroethylmaterial material, and polytetrafluoroethylene (PTFE) has good resistant of high or low temperature, corrosion resistance, weatherability and good mechanical performance by the macromolecular compound of tetrafluoroethene through being polymerized.
Polytetrafluoroethylene (PTFE) can long-term work under-196～260 ℃ wide temperature, and all keeps excellent mechanical property in this scope, does not melt under 260 ℃ temperature, does not also become fragile at low temperature.
Polytetrafluoroethylene (PTFE) resistance to chemical attack and except that the alkali metal of fusion, polytetrafluoroethylene (PTFE) is corroded by any chemical reagent hardly, for example at the concentrated sulfuric acid, nitric acid, hydrochloric acid, even in chloroazotic acid, boil, the equal no change of its weight and performance, also be dissolved in all solvents hardly, it can use for a long time at any kind of chemical mediator.
Polytetrafluoroethylene (PTFE) is nonhygroscopic, does not fire, to oxygen, the equal stabilizer pole of ultraviolet ray, so have excellent weatherability and good anti-aging endurance.
This shows; the polytetrafluoroethylene (PTFE) liner plate is enough to tackle as the interior lining panel of chimney in the tail gas of industrial fuel and contains a large amount of corrosivity sulfuration thing etc., and play the protection inner wall of stack do not contained a large amount of corrosivity sulfuration thing etc. industrial fuel the tail gas contact and corrode.In addition, the polytetrafluoroethylene (PTFE) liner plate is difficult to bond together with other materials because of the surface is comparatively smooth, therefore, the processing that process is special also adopts HTHP hot melt composite methods to make the woven layer of cloth of the compound glass fibre in the back side of polytetrafluoroethylene (PTFE) liner plate, and its purpose mainly is convenient to the polytetrafluoroethylene (PTFE) liner plate and is realized the good one that is formed by connecting by the inwall of woven layer of cloth of glass fibre and chimney.
The chimney lining plate that adopts polytetrafluoroethylene (PTFE) glass fibre backer board of the present invention to make not only can prolong service life of chimney, through experimental result and can use at least 10 years, and greatly reduces use cost and maintenance cost.The chimney that utilizes chimney that polytetrafluoroethylene (PTFE) glass fibre backer board makes as the chimney lining plate and alternative original titanium alloy to make so also makes the manufacturing cost of chimney greatly descend, and has reduced the fund input of enterprise, has alleviated the burden of enterprise.
Polytetrafluoroethylene (PTFE) glass fibre backer board of the present invention also can be used for the interior lining panel or the etch-proof occasion of other need of pipeline applicable to the interior lining panel of chimney.
