Abstract
The utility model discloses a kind of high temperature resistant quartz fibre sealing cord, relate to refractory seals heat-barrier material field, sealing rope comprises the sealing cord body woven by 3 ~ 20 strands of quartz fibre yarns; The quartz fibre single twisting that per share quartz fibre yarn is 5 ~ 11 μm by some diameters is made, and the twist of per share quartz fibre yarn is 140 ~ 280 twists/m.High temperature resistant quartz fibre sealing cord body of the present utility model is solid construction, and when sealing cord body is squeezed, still can keep original form, sealing property is relatively good.The twist of quartz fibre yarn is 140 ~ 280 twists/m, and the quartzy sealing cord body resilience adopting above-mentioned quartz fibre yarn to make is better.
Description
Technical field
The utility model relates to refractory seals heat-barrier material field, is specifically related to a kind of high temperature resistant quartz fibre sealing cord.
Background technology
Glass cord is a kind of heat preserving and insulating material for alternative asbestos, and glass cord has good thermal insulation, ageing resistance and insulating properties, can be used as seal.
When existing glass cord is used as seal, there is following defect:
Glass cord is under the condition of temperature higher than 600 DEG C, there will be crystallization, glass cord after crystallization, its intensity reduces rapidly, when the glass cord that intensity is lower is used as seal, easily rupture, post-rift glass cord sealability is poor, need the seal more renewed to realize sealing function, add sealing cost.
Utility model content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of high temperature resistant quartz fibre sealing cord, and not only sealability is better in high temperature environments, and sealing cost is lower.
For reaching above object, the technical scheme that the utility model is taked is: a kind of high temperature resistant quartz fibre sealing cord, comprise the sealing cord body woven by 3 ~ 20 strands of quartz fibre yarns, the quartz fibre single twisting that per share quartz fibre yarn is 5 ~ 11 μm by some diameters is made, and the twist of per share quartz fibre yarn is 140 ~ 280 twists/m.
On the basis of technique scheme, the organic glue-line of outer surface of described sealing cord body.
On the basis of technique scheme, described organic glue-line adopts silicone resin emulsion to make.
On the basis of technique scheme, the line density of described per share quartz fibre yarn is 220 ~ 670tex.
On the basis of technique scheme, the line density of described per share quartz fibre yarn is 440tex.
On the basis of technique scheme, the twist of described per share quartz fibre yarn is 180 twists/m.
On the basis of technique scheme, the diameter of described quartz fibre monofilament is 7 μm.
On the basis of technique scheme, the diameter of described quartz fibre monofilament is 10 μm.
Compared with prior art, the utility model has the advantage of:
(1) the high temperature resistant quartz fibre sealing cord in the utility model, comprise the sealing cord body be made up of 3 ~ 20 strands of quartz fibre yarns, original form can be kept under temperature is not higher than the condition of 1100 DEG C, compared with glass cord of the prior art, can temperature higher than 600 DEG C, lower than the conditions of 1100 DEG C under keep good sealing property; The twist of per share quartz fibre yarn is 140 ~ 280 twists/m, and the quartzy sealing cord lighter weight adopting this quartz fibre yarn to make, resilience are better, be not only convenient to transport, and sealing property is better.
(2) the quartz fibre rope in the utility model, comprises organic glue-line, and organic glue-line adopts organic siliconresin to make, and ABRASION RESISTANCE and the sealing of quartz fibre rope are better.
(3) in the utility model, the diameter of quartz fibre monofilament is 5 ~ 11 μm, and adopt this monofilament to be the quartz fibre rope that raw material are made, quality is soft, and not only ultimate strength is higher, and service life is longer, effectively can reduce use cost.
Accompanying drawing explanation
