Lub Luag Haujlwm ntawm Basalt Fiber Impregnants
Kev siv cov tshuaj infiltrants yog ib qho ntawm cov kev kho mob txheej txheem feem ntau thiab zoo tshaj plaws hauv kev tsim cov Basalt Fibers. Lub luag haujlwm ua los ntawm tus neeg nkag mus rau hauv cov txheej txheem tsim cov fiber basalt thiab cov txheej txheem tsim cov fiber sib xyaw yog nyob rau hauv plaub qhov chaw hauv qab no.
(1) Lubrication, lub luag haujlwm tiv thaiv
Cov fiber basalt Tus neeg sawv cev infiltration hauv cov roj nplua nyeem tuaj yeem sau qhov sib txawv ntawm cov fibers, tsim cov zaj duab xis lubricating, thiab txo cov coefficient ntawm kev sib txhuam ntawm cov fiber. Yog li ntawd, cov roj nplua nyeem txheej tuaj yeem siv rau hauv cov txheej txheem ua cov fiber basalt kom txo qhov hnav thiab tsim kua muag ntawm cov fiber filament thawj thiab khaws cia lub zog siab dua, thaum txo qhov kev ntxhov siab tsis sib xws los ntawm cov plaub hau filament thawj tawg, kom ua tau raws li qhov yuav tsum tau ua ntawm kev kos duab thiab tom qab ntawd cov pob ntawm stranded, luv luv txiav, textile, thiab lwm yam kev ua haujlwm, xws li txheej nanoparticle hloov kho infiltration tus neeg sawv cev tuaj yeem txhim kho cov fiber basalt bundling, thiab yog li txhim kho lub zog tawg ntawm cov fiber. Tsis tas li ntawd, coated basalt fiber infiltrant tuaj yeem muab ib txheej ntawm cov txheej tiv thaiv rau cov fiber basalt, los tiv thaiv cov tshuaj corrosive sab nraud lossis qhov kub siab rau cov teebmeem tsis zoo ntawm cov fiber basalt.
(2) Kev sib txuas, kev sib sau ua ke
Tus neeg sawv cev impregnating hauv cov khoom sib txuas tuaj yeem ua ntau dua ib qho basalt fiber monofilament sib txuas rau hauv ib pawg ntawm cov kab xev thawj, kom tsis txhob muaj kev ntxhov siab ntawm ob peb monofilaments los ntawm kev tawg ntawm cov kab xev thiab cov kab xev, tab sis kuj tuaj yeem tiv thaiv qhov tshwm sim ntawm kev txiav luv luv ntawm cov xov paj qhib fiber, kom ntseeg tau tias muaj kev ncaj ncees ntawm cov pob fiber. Yog li ntawd, hauv cov txheej txheem luv luv, coated nrog polyurethane-hom infiltration tus neeg sawv cev tuaj yeem txhim kho qhov yooj ywm thiab kev cuam tshuam ntawm basalt fiber composites, uas tuaj yeem tiv thaiv qhov tshwm sim ntawm basalt fiber yarn tawg thiab cov kab xev xoob.
(3) Txhim kho qhov sib xws ntawm qhov sib txuas ntawm basalt fiber thiab cov khoom siv matrix
Tus neeg sawv cev infiltrating tuaj yeem ua rau Cov ntaub ntawv basalt fiber thiab matrixua ke hauv daim ntawv ntawm Tshuaj lom neeg Cov kev sib txuas, thiab txhim kho lub zog sib txuas ntawm cov interfacial, uas ua rau kev ua tau zoo ntawm cov basalt fiber composites zoo dua. Txheej nrog polyethylene-hom infiltrant tuaj yeem txhim kho qhov sib xws ntawm qhov sib txuas ntawm basalt fibers thiab cov ntaub ntawv matrix, thiab cov fiber-reinforced polyethylene resin composites npaj nrog infiltrated basalt fibers ua rau lub zog tensile thiab tensile modulus nce 20% -40% thiab 15% -20%, feem, piv nrog cov ua ntej hloov kho.
(4) Muab cov fiber basalt ib qho kev ua tiav
Kev txheej txheem ntawm cov infiltrant tuaj yeem ua rau cov fiber nto du dua, txhim kho nws qhov chaw, pab txhim kho qhov ua tau ntawm basalt fiber yog li ntawd nws yooj yim dua rau pwm rau hauv cov duab thiab qhov loj me uas xav tau, txhim kho qhov yooj ywm ntawm kev ua tiav, kom tau raws li kev ua tiav ntxiv thiab daim ntawv thov ntawm cov fibers basalt uas xav tau rau kev txiav luv luv, daim kab xev, kev tawg, antistatic, tensile zog. Los ntawm kev sim tensile, nws tuaj yeem pom tias lub zog tensile ntawm basalt fiber nce ntxiv los ntawm 1146.06 MPa mus rau 2115.80 MPa tom qab txheej nrog tus neeg sawv cev infiltrating, uas yog 84.62% siab dua li ntawm cov fiber thawj.
