Electricity fiber coating liquid, and this coating liquid is applied to warp-knitting polyester grid surface, achieve warp-knitting polyester soil by its smart property
The sensing intelligent of work grid.
(2) smart property of material is demarcated in advance according to different conductive phase proportionings.When sensing type warp-knitting polyester soil
When work grid is by External Force Acting, there is notable change in the conductive phase resistivity at stress, by choosing change in resistance rule
Conductive phase proportioning time the most notable, carries out the preparation of masking liquid.The electrical conductive behavior of conducing composite material typically presents typical diafiltration
Phenomenon, as shown in Figure 1.When conductive paste material content increases to a certain threshold value, in a certain region, composite material resistance rate is anxious
Acute decline, this region is referred to as diafiltration region.Smart material has perception and drives function, some conducting polymer composite wood
Material also has agility, shows some special effectses, such as pulling sensitive effect after particular design.Pulling sensitive effect is to draw in outside
Under power effect there is the process (low-resistance → high resistant) changed in electric conductivity.The appearance of pulling sensitive effect is owing to surpassing when composite deformation
When crossing certain marginal value, conductive path is formed high-impedance state by partial destruction.In actual applications, determined by the change of resistivity
The Changing Pattern of each performance indications of material.
Example one:
In road engineering, GSZ is mainly used in soil mass consolidation, prevents sedimentation.For preparing road worthy sensing type
Warp-knitting polyester GSZ, will (its resistivity with strain stress relation formula be with white carbon black as conductive paste materialWith PVC as matrix, and add plasticizer phthalic acid dioctyl ester, heat stabilizer stearic acid
The additives such as barium, form sensing type conductive coating liquid through melting mixing, then are dipped in masking liquid by warp-knitting polyester grid, form institute
The road sensing type warp-knitting polyester grid needed.The type GSZ is laid in roadbed, be possible not only to reinforcing road bed, prevent
Sedimentation, moreover it is possible to carry out detection and localization and preventive maintenance by the change in resistance after stress deformation, so can save big
The fund of amount, decreases quantities.
Example two:
When mining production operation, the stable strong in tunnel is the guarantee of safety in production, for reinforced roadway, generally uses and buries
If the way of geonet, so not only increase the robustness in tunnel, also can reduce construction cost.But nonetheless, owing to enclosing
The effect of the factors such as pressure, still can make wall deformation failure, cause life and property loss, periodically examine according to special equipment
Survey, then time and effort consuming, and operation inconvenience.The mode laying sensing type warp-knitting polyester geonet now can be used to solve problem above.
With Corvic as matrix, melting mixing as the hydrocarbon black powder of conductive phase filler, and add plasticizer, heat stabilizer,
Dispersant, binding agent make coating material, are immersed in this coating liquid by warp-knitting polyester grid, take out and form biography after air-drying solidification
Sense type warp-knitting polyester grid.The type geonet is embedded in tunnel, is possible not only to reinforced roadway wall, moreover it is possible to pass through geonet
Change in resistance after stress deformation carries out detection and localization, overhauls in advance, prevents production accident etc. from occurring, reduces lives and properties
Loss.
Although the detailed description of the invention of the present invention is described by the above-mentioned accompanying drawing that combines, but not the present invention is protected model
The restriction enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme, and those skilled in the art are not
Need to pay various amendments or deformation that creative work can make still within protection scope of the present invention.
