Abstract
The invention relates to a polytetrafluoroethylene porous grid plate and a manufacturing method thereof. The grid plate is formed by combining a plurality of polytetrafluoroethylene square bars and a plurality of polytetrafluoroethylene round bars in an interpenetration way, wherein the lateral surfaces of the polytetrafluoroethylene square bars are provided with a plurality of round holes, and the round holes and the outer diameters of the polytetrafluoroethylene round bars are mutually matched. According to the manufacturing method, grid plates of different shapes can be combined as required; and the manufactured grid plate has the advantages of high strength, simple structure, convenience for manufacturing, short production time, less PTFE (polytetrafluoroethylene) raw material consumption, low manufacturing cost, and the like.
Description
Technical field
The present invention relates to a kind of screen, relate in particular to a kind of Teflon porous grid plate, the grid that the equipment such as tower of oil, chemical industry and petroleum refining industry of being applicable to are used are pulled.
Background technique
In the essential industry such as modern chemical industry, petrochemical industry and oil refining is produced, due to the seriously corroded of chemical mediator, the anticorrosion tower of steel lining teflon (PTFE) is used very generally, and tower is thin and tall structure, the tower of diameter ￠ 1000 have up to 10-30m.But PTFE lining tower is all a plurality of cylindrical shells by long 1-2m to be formed by connecting with flange, between every joint cylindrical shell, is all placed with PTFE multi hole grid, supports the packing ring of different materials above.Because packing ring quantity is many, Heavy Weight, in many meeting, adopt the pure PTFE multi hole grid of mold pressing, sinter molding, because of insufficient strength, does not support the weight of packing ring and deformed damaged forces production pause, environmental pollution, has seriously affected normal production.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of high-strength polytetrafluoroethyl-ne screen, the intensity of pulling to improve the grid that equipment is used such as existing tower.
The technical solution adopted in the present invention is: a kind of Teflon porous grid plate, described screen is interted and combines with the teflon circular rod of some containing strengthening ribs by square of some teflon, the side that described teflon is square is provided with some circular holes, and described circular hole and teflon circular rod external diameter cooperatively interact.
The described plate of deleting can be combined into difformity as required.For tower, generally adopt circle to delete plate, by square of the teflon of some different lengths and the teflon circular rod of some different length containing strengthening ribs, intert and combine.For the square plate of deleting, by square of the teflon of some equal length and the teflon circular rod of some equal length containing strengthening ribs, intert and combine.Described stiffening rib preferably adopts circular reinforcing bar.
Beneficial effect of the present invention: teflon circular rod and square interspersed composite structure of teflon of 1, adopting containing strengthening rib, can effectively solve the problem of pure PTFE multi hole grid insufficient strength, the antiseptic property both with former PTFE multi hole grid, has improved again the intensity of deleting plate.2, this grid plate structure is simple, easy to make, and the production time is short, and PTFE raw material consumption is few, low cost of manufacture, and 3, without large-tonnage hydraulic press, sintering furnace etc., produce equipment, can manufacture this important goods.
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.

Embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, the present embodiment polytetrafluoroethylstephanoporate stephanoporate grid are pulled as circular porous and are deleted plate 5, by square 1 of the teflon of some different lengths and the teflon circular rod of some different length containing strengthening ribs 42, are interted and are combined.The side that described teflon is square 1 is provided with some circular holes 3, and described circular hole 3 cooperatively interacts with teflon circular rod 2 external diameters.For improving support strength and the stressed uniformity, described stiffening rib 4 is circular reinforcing bar, and the spacing between described each circular hole 3 equates.The quantity of square of described teflon and teflon circular rod and thickness are determined according to concrete use occasion.For the plate of deleting of other shapes, can implement with reference to the present embodiment.
The circular porous of the teflon of take is below deleted plate and is pulled making method as example illustrates this polytetrafluoroethylstephanoporate stephanoporate grid:
(A), make square of teflon: as shown in Figure 2 and Figure 3, the pure PTFE sheet material that market is bought, according to deleting rectangular section bar 1 that plate requirement cuts into different length and penetrating circular hole 3 on the brill of the side of section bar (both thickness on one side), the present embodiment, rectangular section bar width is 10mm, thickness is 15mm, and penetrating circular hole 3 diameters are 10mm.
(B), make teflon circular rod: as shown in Figure 4, according to the length of different circular rod, circular reinforcing bar (the present embodiment bar diameter is 10mm) is cut into the circular steel bar of different length, at the some layers of its outside PTFE strip that 0.1mm is thick on cross winding back and forth, (the present embodiment is 25 layers, thick about 2.5mm), again at PTFE band outside wrapping laminated glass fiber band, be placed in stove and be sintered to 380 ℃, be incubated 1 hour, clinkering plasticizing, cooling rear taking-up, solution go outside glass fiber tape the teflon circular rod of containing strengthening rib.
(C), square of the teflon of different length is lined up to circle, the teflon circular rod of different length is inserted respectively to the circular hole of square of the teflon that coordinates with it, made it be combined as circular Teflon porous grid plate as shown in Figure 1.
According to the weight of the size of screen diameter and its packing ring loading above, adopt said method, select thickness and the length of reinforcing bar in rod, can produce specification difference, intensity is enough deletes plate.
