Uhlalutyo lwe-Basalt Fiber Technology
IiMathiriyeli ezikrwada kunye neNkqubo yeMveliso
Imathiriyeli ekrwada ye i-basalt fiber yi intaba-mlilo ye-basalt rock. Yalo Ikhemikhali Ukubunjwa ngokuyinhloko yi-silicon dioxide kunye ne-aluminium oxide, eyongezwa nge-oxides yentsimbi, i-calcium, kunye nabanye. Emva kokutyunyuzwa kunye nokucoca, i-ore ifakwa kwisithando somlilo esinyibilikayo, apho inyibilika ibe yi-magma ene-homogeneous kwiqondo lokushisa eliphezulu elijikelezayo. I-1500 ° C, kwaye emva koko itsalwe kwiifiber eziqhubekayo nge-platinum-rhodium alloy spinneret.
Kuthelekiswa ne IFayibha yeglasi,i-basalt fiber kuphelisa inkqubo yokudibanisa kwaye isebenzisa imathiriyeli enye ekrwada. Xa kuthelekiswa nenkqubo ye-carbonization eyinkimbinkimbi ye-carbon fiber, efuna i-precursor ye-organic, inkqubo yayo yokuvelisa ngokuthe ngqo. Nangona kunjalo, ukuguquguquka ekubunjweni kwe-basalt ore kunokuchaphazela uzinzo lwefayibha, kufuneke ukuba kuhlolwe ngokungqongqo izinto ezikrwada.
Iimpawu zokuSebenza kwePhysical and Chemical
(1) Iinkcazelo ngoomatshini: Ukomelela kwe i-basalt fiber iphakathi kwaleyo yefayibha yeglasi eqhelekileyo kunye nefayibha yekhabhoni, eqhele ukuqala ukusuka kwi-3000 ukuya kwi-4800 MPa, enemodyuli elastiki emalunga ne-90-110 GPa. Oku kungaphezulu kune-E-glass fiber kodwa ingaphantsi kune-high-modulus carbon fiber. Ubude bayo ngexesha lekhefu malunga ne-3%, ebonisa inqanaba elithile lokuqina.
(2) Ukuxhathisa iqondo lobushushu: Uluhlu lwexesha elide lobushushu bokusebenza luyi-260 ° C ukuya kwi-700 ° C, kunye nokumelana nokushisa kwangoko ukuya kwi-1000 ° C. Oku kugqwesileyo kuninzi lwemicu yendalo kunye nemicu yeglasi eqhelekileyo, isondela kwiifiber zeceramic kodwa ngexabiso eliphantsi.
(3) Ukumelana nokuMhlwa: Ukuzinza kwayo kwindawo ye-asidi kunye ne-alkali ingcono kune-fiber yeglasi, ngokukodwa ibonisa phantse akukho konakala kwi-pH 2-11 uluhlu, okwenza ukuba ifaneleke kwiindawo ezibuhlungu ezifana neemeko ezimanzi kunye netyuwa yokutshiza.
(4) Ezinye iinkcazelo ngeempawu: Ine-a ukuhanjiswa kwe-thermal ephantsi (approx. ), ukusebenza kakuhle kokufakelwa kombane, kunye nesantya sokufunxa ukufuma esingaphantsi .
Ukuthelekiswa kweMimandla yeSicelo
(1) Ukomelezwa koLwakhiwo: Xa kuthelekiswa nentsimbi yentsimbi yesiqhelo, i-basalt fiber rebar i-lightweight kunye ne-corrosion-resistant, ekhusela ingxaki ye-concrete carbonation, nangona ixabiso layo lokuqala liphezulu. Xa kuthelekiswa ne-carbon fiber rebar, iyabonelela ukusebenza kakuhle kweendleko.
(2) Ubunzima beMoto: Kumacandelo afana neebhuleki zeebhuleki kunye nezikhuseli zobushushu zokukhupha, ihambelana nokusingqongileyo kune-asbestos kwaye ifezekisa ukunciphisa ubunzima ngaphezulu. xa kuthelekiswa nezinto zetsimbi.
(3) Izixhobo zombane: Isetyenziswe njengento yokuqinisa iibhodi zeesekethe, ukusebenza kwayo kwe-dielectric kuphezulu kunefiber yeglasi, kwaye inqanda imiba yokukhusela umqondiso.
(4) Izinto zokuHluza: Ukumelana kwayo nobushushu obuphezulu kunika inzuzo ebalulekileyo ngaphezu kwezihluzo zefiber zekhemikhali kwintsimi yokucoca igesi ye-flue ephezulu.
Imida yobuGcisa
(1) Iindleko zeMveliso: Ixabiso langoku le-basalt fiber malunga namaxesha angama-2-3 e-fiber ye-E-glass, ngokukodwa ngenxa yokusetyenziswa kwamandla okunyibilika okuphezulu kunye nokugqoka okubalulekileyo kwe-spinneret. Imveliso enkulu inokunciphisa oku malunga ne-1.5 yamaxesha e-glass fiber.
(2) Ulawulo Lwenkqubo: Ukufana kwe-melt kuchaphazela kakhulu i-fiber diameter, efuna ukulawulwa ngokuchanekileyo kwintsimi yeqondo lokushisa kunye nesantya sokudweba.
(3) Ukuziqhelanisa neNkqubo eNzulu: Ukukhethwa kwee-agent zokudityaniswa kwe-bonding kunye ne-resin matrices kungqongqo ngakumbi kune-fiber yeglasi, efuna ukulungiswa okujoliswe kuyo.
Iindlela zoPhuhliso lwezobuGcisa
(1) Itekhnoloji yokucoca izinto ezikrwada: Ukusebenzisa iindlela ezinje ngokwahlukana kwamagnetic kunye nokujikeleza ukunciphisa umxholo wentsimbi kwintsimbi ekrwada, ngaloo ndlela kuphuculwe ukuzinza kwenyibilika.
(2) Ukuphuculwa kweNkqubo yokunyibilika: Ukuphuhlisa iikilns ezintsha ze-electrode-heated ukunciphisa ukusetyenziswa kwamandla malunga xa kuthelekiswa nezibane ezibaswa ngerhasi.
(3) Ukwahluka kweeMveliso: Iindidi ezikhethekileyo ezifana ne-ultra-fine fibers (i-filament diameter enye ) kunye neentsinga ezine-non-circular cross-sections zenziwe.
(4) Ukurisayikilisha: Imicu yenkunkuma inokucolwa kwaye isetyenziswe njenge imixube kwikhonkrithi, ukufikelela kujikelezo lwezibonelelo.
Ukuqukumbela
Xa kuthelekiswa nezinye iintsinga eziphezulu zokusebenza, inzuzo engundoqo ye i-basalt fiber ilele kwinkqubo yayo yonke-yendalo ekrwada kunye nokusebenza ngokulinganayo okubanzi. Nangona amandla ayo aziwayo engekho phezulu njengefayibha yekhabhoni, kwaye umda wayo wobushushu ungaphantsi kunefayibha ye-ceramic, ubuhlobo bayo bokusingqongileyo kunye nokusebenza kakuhle kweendleko kuyenza ingenakuphinda ithathelwe indawo kumacandelo ahlukeneyo amashishini. Ngokulungiswa okuqhubekayo kwenkqubo yokuvelisa, uluhlu lwayo lwezicelo kulindeleke ukuba lwandise ngakumbi.
