Analysis of Basalt Fiber Technology
Raw Materials da Tsarin Samfura
Da albarkatun kasa don basalt fiber shine Dutsen basalt dutsen mai aman wuta. Its Chemical abun da ke ciki shi ne da farko silicon dioxide da aluminum oxide, supplemented da oxides na baƙin ƙarfe, calcium, da sauransu. Bayan an murkushe ma'adinan da tsaftacewa, ana ciyar da ma'adinan a cikin tanderun narkewa, inda aka narkar da shi zuwa magma mai kama da yanayin zafi mai zafi. 1500°C, sa'an nan kuma zana cikin zaruruwa masu ci gaba ta hanyar platinum-rhodium alloy spinneret.
Daura da Gilashin Fiber,basalt fiber yana kawar da tsarin batching kuma yana amfani da ɗanyen abu guda ɗaya. Idan aka kwatanta da hadadden tsarin carbonization na carbon fiber, wanda ke buƙatar precursor na halitta, tsarin samar da shi ya fi kai tsaye. Koyaya, canje-canje a cikin abun da ke tattare da ma'adinai na basalt na iya shafar kwanciyar hankali na fiber, yana buƙatar tabbatar da ingantaccen kayan aiki.
Halayen Ayyukan Jiki da Chemical
(1) Kayayyakin Injini: The tensile ƙarfi na basalt fiber yana tsakanin na talakawa fiber fiber gilashi da carbon fiber, yawanci jere daga 3000 zuwa 4800 MPa, tare da na roba modulus na kamar 90-110 GPa. Wannan ya fi fiber E-glass amma ƙasa da fiber carbon carbon high-modulus. Tsawon sa a lokacin hutu shine kusan 3%, yana nuna wani matakin tauri.
(2) Juriya na Zazzabi: Matsakaicin zafin jiki na aiki na dogon lokaci shine -260°C zuwa 700°C, tare da juriyar zafin jiki nan take har zuwa 1000°C. Wannan ya fi yawancin zaruruwan kwayoyin halitta da filayen gilashi na yau da kullun, suna gabatowa zaruruwan yumbu amma a farashi mai rahusa.
(3) Juriya na Lalata: Kwanciyarsa a cikin yanayin acid da alkali ya fi gilashin fiber, musamman yana nuna kusan babu lalata a cikin pH 2-11, yana sa ya dace da yanayi mai tsanani kamar yanayin damp da gishiri.
(4) Sauran Kayayyakin: Yana da a low thermal conductivity (kimanin. ), Kyakkyawan aikin rufewar wutar lantarki, da yawan sha da danshi wanda bai kai ba .
Kwatanta Filin Aikace-aikace
(1) Ƙarfafa Gine-gine: Idan aka kwatanta da shingen ƙarfe na gargajiya, basalt fiber rebar mai nauyi ne kuma mai jure lalata, wanda ke guje wa matsalar simintin carbonation, kodayake farashinsa na farko ya fi girma. Idan aka kwatanta da carbon fiber rebar, yana bayarwa mafi kyawun farashi-tasiri.
(2) Nauyin Mota: A cikin abubuwan da aka gyara kamar pads ɗin birki da garkuwar zafi, ya fi dacewa da muhalli fiye da asbestos kuma yana samun raguwar nauyi sama da idan aka kwatanta da kayan ƙarfe.
(3) Kayan Aikin Lantarki: An yi amfani da shi azaman kayan ƙarfafawa don allunan kewayawa, aikin dielectric ɗin sa ya fi fiber gilashi, kuma yana guje wa al'amuran garkuwar sigina.
(4) Kayan Tace: Babban juriya na zafinsa yana ba shi babban fa'ida akan matatun fiber sinadarai a fagen tace iskar gas mai zafi mai zafi.
Iyakokin Fasaha
(1) Farashin samarwa: Farashin fiber na basalt na yanzu shine kusan sau 2-3 na fiber E-glass, galibi saboda yawan narkewar kuzarin kuzari da manyan lalacewa na spinneret. Samar da babban sikelin na iya rage wannan zuwa kusan sau 1.5 na fiber gilashi.
(2) Sarrafa Tsari: Daidaitaccen narke yana da tasiri sosai akan diamita na fiber, yana buƙatar daidaitaccen iko na filin zafin jiki da saurin zane.
(3) Daidaitawar Gudanar da Zurfafawa: Zaɓin wakilai masu haɗawa don haɗawa tare da matrices resin yana da ƙarfi fiye da fiber gilashi, yana buƙatar haɓakawa da aka yi niyya.
Abubuwan Ci gaban Fasaha
(1) Fasahar Tsabtace Danyen Abu: Yin amfani da hanyoyi kamar rarrabuwar maganadisu da flotation don rage abun cikin baƙin ƙarfe a cikin ma'adinan, don haka inganta kwanciyar hankali.
(2) Inganta Tsarin narkewa: Ƙirƙirar sabbin ɗumbin kiln na lantarki don rage yawan kuzari da kusan idan aka kwatanta da na gargajiya da ake harba gas.
(3) Bambance-bambancen Samfura: Iri na musamman kamar filaye masu kyau (diamita na filament guda ɗaya ) kuma an haɓaka zaruruwa tare da sassan giciye marasa madauwari.
(4) Sake yin amfani da su: Za a iya murkushe zaruruwan sharar gida kuma a yi amfani da su azaman admixtures a kankare, cimma albarkatun wurare dabam dabam.
Kammalawa
Idan aka kwatanta da sauran manyan ayyuka zaruruwa, core amfanin basalt fiber ya ta'allaka ne a cikin tsarin sa na duk-nau'i-nau'i na albarkatun kasa da ma'auni daidaitaccen aiki. Duk da cewa ƙarfin da aka sani bai kai girman fiber carbon ba, kuma iyakar zafinsa ya yi ƙasa da filayen yumbura, abokantakar muhalli da ingancin sa ya sa ba za a iya maye gurbinsa ba a sassa daban-daban na masana'antu. Tare da ci gaba da inganta tsarin samarwa, ana sa ran kewayon aikace-aikacen sa zai kara fadada.
