Cov xov textile tuaj yeem faib ua cov xov rau kev weaving thiab cov xov rau lwm yam kev siv hauv kev lag luam; cov xov weaving feem ntau yog nyob rau hauv daim ntawv ntawm lub raj bobbins thiab conical bobbins.

Basalt Fiber Chopped Strand

Nws yog ib yam khoom ua los ntawm kev txiav cov basalt fiber filaments tas mus li. Cov fibers yog coated nrog ib tug (silane) sizing agent. Yog li ntawd, basalt fiber chopped strand yog cov khoom siv xaiv rau kev txhawb nqa thermoplastic resins thiab kuj yog cov khoom siv zoo tshaj plaws rau kev txhawb nqa pob zeb. Basalt yog ib qho khoom siv pob zeb volcanic ua tau zoo. Cov silicate tshwj xeeb no muab cov basalt fiber zoo heev rau kev tiv thaiv tshuaj lom neeg, tshwj xeeb tshaj yog qhov zoo ntawm kev tiv thaiv alkali. Yog li ntawd, basalt fiber yog ib yam khoom zoo heev los hloov polypropylene (PP) thiab polyacrylonitrile (PAN) rau kev txhawb nqa cement; nws kuj yog ib yam khoom sib tw heev los hloov polyester fibers, lignin fibers, thiab lwm yam, hauv asphalt concrete, uas tuaj yeem txhim kho qhov kub thiab txias, qhov kub thiab txias qis, thiab kev tiv thaiv qaug zog ntawm asphalt concrete.

Cov Xov Paj Basalt Fiber Texturized

Cov xov paj basalt fiber raug ua los ntawm lub tshuab ua kom muaj zog heev los tsim cov xov paj basalt fiber texturized. Lub hauv paus ntsiab lus ntawm kev tsim yog: cua ceev ceev nkag mus rau hauv cov channel texturizing, tsim kom muaj kev ntxhov siab. Qhov kev ntxhov siab no yog siv los faib cov xov paj basalt, ua rau lawv tsim cov xov paj zoo li lub voj voog, yog li ua rau cov xov paj basalt loj thiab tsim cov xov paj texturized.

Basalt Fiber Npuag, tseem hu ua Basalt Fiber Woven Npuag

Nws yog woven siv high-performance basalt fiber tom qab cov txheej txheem xws li twisting thiab warping. Basalt fiber ntaub yog ib tug high-performance ntaub nrog zoo heev cov khoom, siab zog, sib xws textures, tiaj tus nto, thiab ntau yam weaving techniques. Nws muaj peev xwm woven rau hauv low-density, breathable, lub teeb, thiab nyias cov ntaub, los yog high-density, high-strength, tuab, thiab tawv cov ntaub. Feem ntau basalt fiber ntaub suav nrog basalt fiber tiaj weave, basalt fiber twill weave, basalt fiber satin weave, basalt fiber ob-weft weave, basalt fiber daim kab xev, thiab lwm yam.

Basalt Fiber Koob Punched Felt

Cov xov basalt fiber uas raug txiav ua tej daim me me, thiab tom qab ntawd cov txheej lev uas raug txiav ua tej daim me me raug txhawb nqa thiab sib xyaw nrog cov ntaub scrim siv cov txheej txheem needling lossis hydroentangling los tsim ib daim ntawv ua ke. Tom qab ntawd nws raug kho los ntawm kev impregnation thiab ziab kom ua tiav cov ntaub uas raug xuas nrog koob (kev kho tom qab kuj tseem tuaj yeem tsis suav nrog).

Cov Khoom Siv Basalt Fiber

Piv nrog cov fibers high-tech xws li carbon fiber, aramid, thiab ultra-high molecular weight polyethylene fiber (UHMWPE), basalt fiber tsis yog tsuas yog muaj lub zog siab thiab cov yam ntxwv siab modulus ntawm cov fibers high-tech, tab sis kuj muaj cov khoom zoo heev xws li kev tiv thaiv kub siab zoo (-269 ° C txog 760 ° C), kev tiv thaiv oxidation, kev tiv thaiv hluav taws xob, kev rwb thaiv cua sov, kev rwb thaiv suab, kev lim dej zoo, lub zog compressive siab thiab lub zog shear, thiab kev tsim nyog rau kev siv hauv ntau qhov chaw, nrog rau qhov sib piv zoo ntawm tus nqi. Nws yog cov khoom siv inorganic tsis yog hlau thiab cov khoom siv tshiab thiab cov fiber high-tech uas tuaj yeem ua tau raws li qhov xav tau kev txhim kho ntawm lub teb chaws kev lag luam yooj yim. Basalt fiber thiab nws cov khoom sib xyaw tuaj yeem ua tau zoo dua cov kev xav tau ntawm cov ntaub ntawv hauv cov teb xws li kev tsim kho kev tiv thaiv teb chaws, kev thauj mus los, kev tsim kho, kev lag luam petrochemical, kev tiv thaiv ib puag ncig, hluav taws xob, aviation, thiab aerospace, ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev tsim kho kev tiv thaiv teb chaws, cov haujlwm loj, thiab kev txhim kho cov qauv kev lag luam. Nws yog ob qho tib si cov khoom siv ntsuab uas ua tau raws li qhov xav tau ntawm ib puag ncig ntawm lub xyoo pua 21st thiab kev lag luam khoom siv tshiab sib tw nrog kev txhim kho ruaj khov hauv kev lag luam fiber ntau thoob ntiaj teb. Tshwj xeeb, Tuam Tshoj twb muaj cov cai tswjfwm kev txawj ntse rau kev tsim cov thev naus laus zis thiab cov txheej txheem basalt fiber, thiab tau ua tiav qib siab thoob ntiaj teb nrog "qhov zoo dua tom qab." Yog li ntawd, kev txhim kho cov fiber basalt thiab nws cov khoom siv sib xyaw ua ke yog qhov tseem ceeb heev.

Daim Ntawv Thov Basalt Fiber Hauv Cov Khaub Ncaws Ua Haujlwm
