I-Basalt Fiber: Izinto Ezintsha Eziluhlaza Ezisebenza Kakhulu, Iimveliso Zazo, kunye Nezicelo Zazo

Izinto zefayibha yeBasaltinemisebenzi enamandla. Ngoko ke, iveliswa njani ifayibha yebasalt? Yifayibha eqhubekayo eyenziwe ngokutsalwa kwesantya esiphezulu kwezinto zelitye lebasalt emva kokuba zinyibilikisiwe kwi-1450°C ukuya kwi-1500°C nge-platinum-rhodium alloy spinneret. Ifayibha yebasalt inombala omdaka okanye wegolide. Ifayibha yebasalt luhlobo olutsha lwezinto zefayibha ezingaphiliyo, ezinobuhlobo nokusingqongileyo, eziluhlaza, nezisebenza kakuhle. Yinto entsha yenkulungwane yama-21 eluhlaza, enobuhlobo nokusingqongileyo, kwaye ayingcolisi, kwaye yenye yeefayibha ezine eziphambili zaseTshayina ezinobuhlobo nokusingqongileyo. Ifayibha yebasalt ibonisa iipropati ezibalaseleyo ngokwamandla, ukumelana namaqondo obushushu aphezulu naphantsi, ukumelana nokugqwala, ukuthintela ubushushu, ukuthintela isandi, ukuthintela ilangatye, kunye Ikhemikhali kunye nokufakelwa kombane.

Ukuzulazula kweBasalt Fiber

Yimbumba edibeneyo eyenziwe ngokudibanisa iifilaments ezininzi ezihambelanayo okanye iifilaments ezihambelanayo enye ngaphandle kokujika. Amandla okutsalwa kwe-7 - 13 μm xa ujikeleza yi-≥0.65 N/tex, i-elastic modulus yi-≥95 GPa, kwaye ukunwebeka ngexesha lokuqhekeka yi-≥2.6%. I-Basalt Fiber Ayinawo nje amandla aphezulu, imodulus ephezulu, kunye nokumelana nempembelelo okufana neefayibha zobugcisa obuphezulu ezifana nePPTA (Poly-p-phenylene terephthalamide) kunye neUHMWPE (i-polyethylene enobunzima obuphezulu kakhulu), kodwa ikwanawo nokumelana nobushushu obuphezulu kunye nokumelana nokukhanya. Ingakumbi, amandla okubopha i-interface kunye ne-resin aphezulu kakhulu. Ke ngoko, ukujikeleziswa kwe-basalt kweenkcukacha ezahlukeneyo kungasetyenziselwa ukulukwa, ukujija, kunye nokuluka ii-preforms ezahlukeneyo zezinto ezidityanisiweyo.

Intambo yeTayile yeBasalt Fiber

Yintambo eyenziwe ngokujija nokupeyinta iifilaments ezininzi ze-basalt fiber, ububanzi bayo buyi-≤ 9 μm. Intambo yelaphu inokwahlulwa ngokubanzi ibe yintambo yokuluka kunye nentambo yokusetyenziswa kwezinye iindlela zoshishino; intambo yokuluka ikwimo yeetyhubhu kunye nee-bobbins ezikhonkrithi.

I-String eqoshiweyo ye-Basalt Fiber

Yimveliso eyenziwe ngokusika iifilamenti zefayibha ye-basalt eqhubekayo. Iifayibha zigqunywe nge-arhente yokulinganisa (i-silane). Ke ngoko, umsonto onqunqiweyo wefayibha ye-basalt yeyona nto ikhethwayo yokuqinisa ii-resin ze-thermoplastic kwaye ikwayeyona nto ilungileyo yokuqinisa ikhonkrithi. I-Basalt yinxalenye yelitye lentaba-mlilo esebenza kakhulu. Le silicate ikhethekileyo inika ifayibha ye-basalt ukumelana okuhle kweekhemikhali, ngakumbi inzuzo yokumelana ne-alkali. Ke ngoko, ifayibha ye-basalt sisixhobo esihle kakhulu sokutshintsha i-polypropylene (PP) kunye ne-polyacrylonitrile (PAN) yokuqinisa ikhonkrithi yesamente; ikwangumveliso okhuphisana kakhulu wokutshintsha iifayibha ze-polyester, iifayibha ze-lignin, njl.njl., kwikhonkrithi ye-asphalt, enokuphucula uzinzo lobushushu obuphezulu, ukumelana nokuqhekeka kobushushu obuphantsi, kunye nokumelana nokudinwa kwekhonkrithi ye-asphalt.

Intambo Enemisonto yeBasalt Fiber

Intambo yefayibha yeBasalt icutshungulwa ngomatshini wokwenza i-texturizing osebenza kakuhle ukuvelisa intambo yefayibha yebasalt. Umgaqo wokwenza ngulo: ukuhamba komoya ngesantya esiphezulu kungena kumjelo wokwenza i-texturizing, kudala i-turbulence. Le turbulence isetyenziselwa ukusasaza iintambo zebasalt, okubangela ukuba zenze iintambo ezifana ne-loop, ngaloo ndlela zinika ubukhulu kwi-fiber yebasalt kwaye zivelise intambo yesitayile.

Ilaphu le-Basalt Fiber, ekwaziwa ngokuba yi Ilaphu elilukiweyo leBasalt Fiber

Ilukwa kusetyenziswa i-basalt fiber esebenza kakhulu emva kweenkqubo ezifana nokujija nokujika. Ilaphu le-basalt fiber lilaphu elisebenza kakhulu elineempawu ezibalaseleyo, amandla aphezulu, ubume obufanayo, umphezulu othe tyaba, kunye neendlela ezahlukeneyo zokuluka. Lingalukwa libe ngamalaphu axineneyo, aphefumlayo, alula, nabhityileyo, okanye amalaphu axineneyo, aqinileyo, aqinileyo, naqinileyo. Amalaphu aqhelekileyo e-basalt fiber aquka i-basalt fiber plain weave, i-basalt fiber twill weave, i-basalt fiber satin weave, i-basalt fiber double-weft weave, i-basalt fiber tape, njl.

I-Basalt Fiber Needle Punched Felt

Umsonto osikiweyo wefayibha yebasalt uyafakwa kwikhadibhodi, uze emva koko umaleko womathi osikiweyo uqiniswe kwaye uhlanganiswe nge-scrim kusetyenziswa iinkqubo ze-needling okanye ze-hydroentangling ukwenza i-united whole. Emva koko iphathwa ngokufaka i-impregnation kunye nokomisa ukuze yenze i-felt egqityiweyo yokubhoboza inaliti (emva konyango nayo ingashiywa).

Ii-Composites ze-Basalt Fiber

Xa kuthelekiswa neefayibha zobuchwepheshe obuphezulu ezifana nefayibha yekhabhoni, i-aramid, kunye nefayibha ye-polyethylene enobunzima be-molecular obuphezulu kakhulu (UHMWPE), ifayibha ye-basalt ayinazo nje kuphela iimpawu zamandla aphezulu kunye ne-modulus ephezulu yeefayibha zobuchwepheshe obuphezulu, kodwa ikwanazo neempawu ezintle ezifana nokumelana okuhle nobushushu obuphezulu (-269°C ukuya kwi-760°C), ukumelana ne-oxidation, ukumelana nemitha, ukufudumala kobushushu, ukufudumala kwesandi, ukucoca okulungileyo, amandla aphezulu oxinzelelo kunye namandla okucheba, kunye nokufaneleka ukusetyenziswa kwiindawo ezahlukeneyo, kunye nomlinganiselo olungileyo weendleko kunye nokusebenza. Yinto yendalo ecocekileyo engeyiyo isinyithi kwaye yimpahla entsha esisiseko kunye nefayibha zobuchwepheshe obuphezulu enokwanelisa iimfuno zophuhliso lwamashishini asisiseko oqoqosho lwesizwe. Ifayibha ye-basalt kunye nezinto zayo ezidityanisiweyo zinokuhlangabezana ngcono neemfuno zezixhobo zokwakha kwiindawo ezifana nokwakhiwa kokhuselo lwesizwe, ukuthutha, ukwakha, ishishini le-petrochemical, ukhuseleko lokusingqongileyo, i-elektroniki, inqwelomoya, kunye neenqwelo-moya, idlala indima ebalulekileyo ekukhuthazeni ukwakhiwa kokhuselo lwesizwe, iiprojekthi ezinkulu, kunye nokuphuculwa kwesakhiwo semizi-mveliso. Yinto eluhlaza ehlangabezana neemfuno zendalo zenkulungwane yama-21 kwaye yishishini elitsha lezinto ezikhuphisanayo elinophuhliso oluzinzileyo kwicandelo lefayibha lobuchwepheshe obuphezulu kwihlabathi liphela. Ngokukodwa, iTshayina sele inamalungelo epropathi yengqondo azimeleyo kwitekhnoloji yokuvelisa ifayibha ye-basalt kunye nenkqubo, kwaye ifikelele kwinqanaba elikhokelayo kwihlabathi liphela "ngenzuzo ezayo kamva." Ke ngoko, ukuphuhlisa ngamandla ifayibha ye-basalt kunye neshishini layo lezinto ezidityanisiweyo ngokungathandabuzekiyo kubaluleke kakhulu.

Ukusetyenziswa kwe-Basalt Fiber kwi-Functional Apparel

Ilaphu lefayibha yeBasalt linamandla aphezulu, alinamlilo unaphakade, linokumelana namaqondo obushushu afutshane angaphezu kwe-1000°C, kwaye lingasetyenziswa ixesha elide kwindawo engama-760°C, nto leyo eyenza ukuba libe yindawo efanelekileyo yokuthatha indawo yelaphu lefayibha ye-asbestos kunye neglasi. Ilaphu lefayibha yeBasalt linamandla aphezulu okuqhekeka, ukumelana nobushushu obuphezulu, kunye nokungatshabhisi komlilo unaphakade. Liyindlela engabizi kakhulu kuneefayibha ezisebenzayo neziphambili ezifana neNomex (Aramid 1313), iKevlar (Aramid 1414), iZylon (PBO fiber), kunye nefayibha yekhabhoni. Ilaphu lefayibha yeBasalt linokudaywa kwaye liprintwe emva kokudaywa kweekhemikhali kunye nokugqitywa. Emva kokugqitywa kokusebenza, njengokugqitywa kwe-organofluorine, lingenziwa libe yilaphu eligxotha ioyile, elithintela amanzi, kunye nelithintela umlilo unaphakade. Iimpahla ezinokwenziwa ngelaphu lefayibha yeBasalt ziquka: izixhobo zokuphuma kwabacimi-mlilo, iisuti zokuthintela ubushushu, iisuti zokusondela, iimpahla zokukhusela zabasebenzi besithando, iimpahla zomsebenzi zokuwelda, kunye neesuti ezithintela umlilo zabasebenzi bezithuthi zomkhosi, njl.
