As seen from the above table, the andesite fiber that the present invention relates to is compared with basalt fibre, glass fibre commonly used, has the following advantages:
(1), Young's modulus exceeds expensive S glass fibre; Be used for Woven fabric weight at 150～210g/m
2Product the time, weaving performance is good; Can make insulating product and matrix material in order to replace the S glass fibre, make hard armor, various GFRP product and portion C FRP product.For example, utilize the E glass fibre to produce Glass Steel Tube, can only anti-25 normal atmosphere, caliber is 2 meters to the maximum, and makees Glass Steel Tube with andesite fiber, then can anti-60 normal atmosphere, caliber can reach 3.5 meters.Under some Working environment, andesite fiber can partly replace carbon fiber or aramid fiber.
(2), because water resistance is good, even surpass the E glass fibre that water tolerance has reached the I level, the cotton plate made from the andesite fiber of diameter 17～25 μ m has enough water-permeables and flexibility during as agriculture substratum.Through repeatedly freezing and thawing, soak and dry recycle, the cotton plate of andesite shows enough stability.Because its anti-atmospheric action can be in order to reinforce building near water such as dash slope earth dam, fending groin and irrigation canals and ditches.
(3), thermotolerance is better than mineral wool and E glass fibre, the high resistant to elevated temperatures quartz glass fibre of price near output is little.When working under 400 ℃ of temperature, its breaking tenacity still can keep 96%; When working under 600 ℃ of temperature, its breaking tenacity still can keep 90% green strength, even and also can only keep good mineral wool at this moment 50～60% intensity, glass wool is completely destroy then.If andesite fiber is handled under 880～920 ℃ in advance, fiber can also be worked under 960 ℃ and can not occurred shrinking.If the short yarn cutting of andesite fiber is bonded into felt with sodium～montomorillonite～bentonite slurry, handled 5 minutes down at 550 ℃, can improve its water tolerance, and can bring up to working temperature on 1000 ℃ of quartz glass fibre.Sometimes fiber also will stand vibration except standing heat effect.The heat of andesite fiber under the 500 ℃ of temperature stability of shaking is still constant, and original weight loses less than 1.3%; In the time of 900 ℃, only 2%.The andesite fiber of low unit weight, low heat conductivity, low rate of moisture absorption and high chemical stability also can be used as the most effective very low temperature thermal insulation material of liquid nitrogen containers such as (196 ℃) or equipment except can be used for high temperature thermal insulation material, and the E glass fibre can only be anti--60 ℃.There is not the carcinogenic problem that may cause when making lagging material with asbestos in andesite fiber when the lagging material.
(4), since sound absorption coefficient than E glass fibre height, andesite fiber also is efficient sound-proof material, and fire prevention, can be used for kino and other saloons with the form of baffle blanket or plate.
(5), because the filter factor height, andesite fiber also successfully purify air or the equipment of flue gas in, as high-temperature-resistant filtering material.
(6), the tensile strength of andesite fiber under 200～300 ℃ of temperature will improve 30%, and general glass fibre descends 23%.Andesite fiber also can keep higher-strength under the hot water effect.For example, the intensity of basalt fibre can keep 1000 hours under 80 ℃ of water effects, and general glass fibre is less than just losing intensity in 200 hours.Andesite fiber is exposed to the sun 47 ℃ of strong sunlight still can keep intensity in 2000 hours.
(7), andesite contains the conductive oxide less than 20%, the glass fibre that contains conductive oxide generally can not be used to prepare insulating material, but the tangent of the dielectric loss angle of andesite fiber is close with the E glass fibre, the andesite fiber that the application specific treating compound was handled, its tangent of the dielectric loss angle also hangs down 60% than general glass fibre, thereby can be used as heat-resistant insulation material, can be widely used in the fields such as printed-wiring board (PWB) manufacturing of electronic industry.
(8), andesite fiber has good reinforcing effect.The hot candied test of ultimate fibre shows that the adhesive capacity of andesite fiber and epoxy polymer is higher than the E glass fibre, and also can further improve after adopting silane coupling agent to handle.Therefore, andesite fiber can replace being about to the strongthener of the asbestos of forbidding as high-temperature-resistant structure matrix material, rubber technology goods etc., also can be used for making the strongthener of the wearing piece of stopper, clutch coupling etc.
(9), the ECR glass fibre that the acid resistance of andesite fiber is higher than the valency through being commonly used for acid-resistant glass steel strongthener is not bad; Its alkali resistance is suitable with AR alkali resistant glass fibre commonly used in the market, can replace the AR glass fibre, fields such as fiber reinforced concrete member (GRC) that is applied to be in great demand or road surface geo-grid.
