Lub luag haujlwm ntawm Basalt Fiber Impregnants
Kev siv cov infiltrants yog ib qho ntawm cov txheej txheem ntau tshaj plaws thiab muaj txiaj ntsig zoo hauv kev tsim khoom Basalt Fiber ntaus. Lub luag hauj lwm ua si los ntawm infiltrant nyob rau hauv basalt fiber molding thiab fiber ntau cov txheej txheem yog nyob rau hauv plaub qhov chaw hauv qab no.
(1) Lubrication, tiv thaiv lub luag haujlwm
Basalt fiber ntau infiltration tus neeg saib xyuas nyob rau hauv lub lubricant tuaj yeem sau qhov sib txawv ntawm cov fibers, tsim cov zaj duab xis lubricating, thiab txo cov coefficient ntawm kev sib txhuam ntawm fiber. Yog li ntawd, txheej txheej lubricants tuaj yeem siv rau hauv cov txheej txheem basalt fiber ntau los txo qhov hnav thiab tsim kua muag ntawm thawj fiber ntau filament thiab khaws lub zog ntau dua, thaum txo qhov tsis sib xws los ntawm cov thawj filament plaub hau breakage tshwm sim, kom ua tau raws li qhov yuav tsum tau ua ntawm kev kos duab thiab cov khoom txuas ntxiv ntawm kev tso tseg, luv txiav, textile, thiab lwm yam kev ua haujlwm, xws li cov khoom siv fiber ntau, xws li coatings, coatings, thiab lwm yam. bundling, thiab yog li txhim kho lub zog tawg ntawm fiber ntau. Tsis tas li ntawd, coated basalt fiber ntau infiltrant tuaj yeem muab txheej txheej tiv thaiv rau basalt fibers, tiv thaiv cov khoom siv sab nraud los yog qhov kub thiab txias ntawm qhov tsis zoo ntawm basalt fibers.
(2) Bonding, bunching nyhuv
Tus neeg sawv cev impregnating nyob rau hauv cov khoom sib txuas tuaj yeem ua tau ntau tshaj li ib qho basalt fiber monofilament bonding rau hauv ib pawg ntawm cov ntaub qub, kom tsis txhob muaj kev ntxhov siab ntawm ob peb monofilaments tshwm sim los ntawm kev tawg ntawm cov lo lo ntxhuav thiab lo lo ntxhuav phenomenon, tab sis kuj tuaj yeem tiv thaiv qhov tshwm sim ntawm luv luv txiav txheej txheem ntawm cov xov paj qhib fiber ntau, los xyuas kom meej lub bundle ntawm fiber ntau. Yog li ntawd, nyob rau hauv cov txheej txheem luv luv, coated nrog polyurethane-hom infiltration tus neeg saib xyuas tuaj yeem txhim kho qhov yooj thiab cuam tshuam ntawm basalt fiber ntau, uas tuaj yeem zam qhov tshwm sim ntawm basalt fiber yarn cracking thiab xoob silk phenomenon.
(3) Txhim khu kev sib raug zoo ntawm kev sib txuas ntawm basalt fiber thiab matrix khoom
Tus neeg sawv cev infiltrating tuaj yeem ua rau basalt fiber thiab matrix cov ntaub ntawvua ke nyob rau hauv daim ntawv ntawm Tshuaj bonds, thiab txhim khu lub interfacial bonding quab yuam, uas nyob rau hauv lem txhim kho tag nrho cov kev ua tau zoo ntawm basalt fiber ntau composites. Coated nrog polyethylene-hom infiltrant tuaj yeem txhim kho kev sib raug zoo ntawm kev sib txuas ntawm basalt fibers thiab matrix cov ntaub ntawv, thiab cov fiber ntau-reinforced polyethylene resin composites npaj nrog infiltrated basalt fibers nce lub zog tensile thiab tensile modulus los ntawm 20% -40% thiab 15% -20%, ntsig txog kev hloov kho ua ntej.
(4) Muab basalt fiber ntau ua haujlwm
Txheej cov infiltrant tuaj yeem ua rau fiber ntau smoother, txhim kho nws nto, pab txhim kho formability ntawm basalt fiber ntau kom nws yooj yim rau pwm rau hauv qhov xav tau cov duab thiab qhov loj me, txhim khu kev ua haujlwm yooj yim, kom tau raws li kev ua haujlwm ntxiv thiab kev siv cov basalt fibers uas yuav tsum tau ua rau luv luv, daim kab xev, dispersion, antistatic, tensile zog. Los ntawm kev ntsuas tensile, nws tuaj yeem pom tias lub zog tensile ntawm basalt fiber ntau tau nce los ntawm 1146.06 MPa rau 2115.80 MPa tom qab txheej txheej nrog tus neeg ua haujlwm infiltrating, uas yog 84.62% siab dua li ntawm cov khoom qub.
