Ukukhethwa kwe-basalt fiber eluhlaza kanye nokucubungula

Enqubweni ende yokuziphendukela kwemvelo komhlaba, i-basalt, njengomthombo wemvelo obalulekile, i-genesis yayo eyingqayizivele nokusabalalisa okubanzi kuyenza ibe impahla eluhlaza efanelekile yokukhiqiza ukusebenza okuphezulu. I-Basalt Fibers. Kuleli phepha, sizoxoxa ngezici, izindlela zokukhetha kanye nenqubo yokwelashwa kwe-basalt.

Izakhiwo ze-basalt

I-Basaltkwakhiwa ukupholisa okusheshayo nokuqina kwe-magma kusuka ekuqhumeni kwentaba-mlilo, futhi izakhi zayo eziyinhloko zihlanganisa i-silica (SiO₂), i-aluminium oxide (Al₂O₃), i-iron oxide (Fe₂O₃), i-calcium oxide (CaO) ne-magnesium oxide (MgO). Imvamisa imnyama noma imnyama ngokumpunga ngokubukeka, inomzimba omuhle kakhulu futhi Amakhemikhali izakhiwo futhi isatshalaliswa kabanzi emhlabeni wonke, kufaka phakathi iHawaii, i-Iceland, nezindawo ezimbalwa zaseChina.

Imibandela yokukhethwa kwezinto zokusetshenziswa

Ukukhiqizwa kwekhwalithi ephezulu ye-basalt fibers kuncike ezintweni ezingavuthiwe ezihlangabezana nezidingo ezithile:

Ukwakheka kwamakhemikhali:

I-Silicon Dioxide: okuqukethwe kufanele kube phakathi kuka-45% -55% ukuze kuqinisekiswe i-viscosity efanele kanye ne-fluidity ngesikhathi senqubo yokuncibilika.

I-aluminium oxide: ngokuvamile phakathi kuka-12% -16% ukuthuthukisa ukumelana nokushisa okuphezulu.

I-calcium oxide ne-magnesium oxide: I-8% -12% ye-calcium oxide kanye ne-6% -10% ye-magnesium oxide isetshenziselwa ukulawula izakhiwo zokuncibilika.

I-iron oxide: hhayi ngaphezu kuka-10%, inani elilinganiselwe lingasetshenziswa njenge-flux.

Izinto ezibonakalayo:

Isakhiwo esilinganayo nesiminyene: inciphisa izimbobo zangaphakathi kanye nokuqhekeka futhi iqinisekise ukubunjwa okufanayo kanye nezinga lokushisa ngesikhathi sokuncibilika.

Ubulukhuni obumaphakathi: kulula ukucutshungulwa kusayizi wezinhlayiyana ezifanele, ukugwema inkinga yobulukhuni noma ukuthamba okwedlulele.

Ibanga lephoyinti lokuncibilika: Indawo encibilikayo efanelekile kufanele ibe phakathi kuka-1450℃-1550℃ ukuze kuqinisekiswe ukuncibilika okugcwele.

Izidingo zokuhlanzeka:I-basalt yokuhlanzeka okuphezulu iyisisekelo sokukhiqizwa kwemicu yekhwalithi ephezulu, edinga ukususwa kokungcola okuyingozi njengesulfure ne-phosphorus.

Izinqubo zokwelapha impahla eluhlaza

Ukuze uqinisekise ikhwalithi ye-basalt fibers, uchungechunge lwezinqubo zokwelapha lubalulekile:

Ukwelashwa kwangaphambili kwezinto ezingavuthiwe: ukuhlunga nokukhipha ukungcola ukuze kuqinisekiswe ukuhlanzeka kwezinto ezingavuthiwe.

Ukuchoboza nokugaya: ukuchoboza i-basalt enkulu ibe yizinhlayiya ezincane ukuze zicutshungulwe ngokulandelayo.

Ukuhlanganisa nokuhlanganisa: kusetshenziswa ukuxuba kwegesi yokucindezela okuphezulu ukuze kuqinisekiswe ukuthi impushana ihlangene ngokugcwele.

I-Homogenization: Thuthukisa ukuvumelana kwezinto zokusetshenziswa ngokusebenzisa i-homogenization ukuze uqinisekise ukwakheka kwamakhemikhali okuzinzile nezici zokuncibilika.

Ukuncibilika kwezinga lokushisa eliphezulu: Ukuncibilika kwezinga lokushisa eliphezulu nokunyakazisa esithandweni ukuze kuzuzwe izinga eliphezulu le-homogenization.

Isiphetho

I-Basalt, njengomthombo wemvelo ocebile, uyisisetshenziswa esibalulekile sokwenziwa kokusebenza okuphezulu imicu ye-basalt. Ngokukhetha okuqinile kwempahla eluhlaza kanye nezinqubo zokwelapha, ingaqinisekisa ukukhiqizwa kwemicu ye-basalt yekhwalithi ephezulu, esetshenziswa kabanzi emikhakheni eminingi, njenge-aerospace, ukwakhiwa, kanye nezimoto. Ngokuthuthuka okuqhubekayo kobuchwepheshe, i-basalt nezinto zayo ze-fiber izodlala indima ebalulekile emikhakheni eminingi futhi ikhuthaze inqubekelaphambili nokuthuthukiswa komphakathi. Ngakho-ke, ukuthuthukiswa okunengqondo nokusetshenziswa kwalo mcebo wemvelo kuzoletha inani elikhulu esintwini.
