Ukwakhiwa kwamakhemikhali e-basalt
Kuyaziwa ukuthi uqweqwe loMhlaba lwakhiwe ngamatshe angenalutho, ama-sedimentary kanye ne-metamorphic.I-Basalt wuhlobo lwetshe elivuthayo.Amadwala e-igneous amadwala akhiwa lapho i-magma iqhuma ngaphansi komhlaba futhi ihlangene phezulu.Amadwala e-igneous aqukethe ngaphezu kuka-65% we-SiO2amatshe ane-acidic, njenge-granite, futhi lawo aqukethe ngaphansi kuka-52% S0 abizwa ngokuthi amadwala ayisisekelo, njenge-basalt.Phakathi kwalokhu okubili kukhona amatshe angathathi hlangothi njenge-andesite.Phakathi kwezingxenye ze-basalt, okuqukethwe kwe-SiO2iningi liphakathi kuka-44% -52%, okuqukethwe kwe-Al2O3iphakathi kuka-12% -18%, kanye nokuqukethwe kwe-Fe0 ne-Fe203iphakathi kuka-9% -14%.
I-Basalt iyi-refractory mineral raw material enezinga lokushisa elincibilikayo elingaphezu kuka-1500 ℃.I-iron ephezulu yenza i-fiber bronze, futhi iqukethe i-K2O, MgO kanye ne-TiO2ezidlala indima ebalulekile ekuthuthukiseni ukumelana kwamanzi nokugqwala kwefiber.
I-basalt ore ingeye-volcanic magma ore, enokuqina kwamakhemikhali emvelo.I-Basalt ore iyingxenye eyodwa yezinto ezingavuthiwe zokucebisa, ukuncibilika kanye nekhwalithi efanayo.Ngokungafani nokukhiqizwa kwe-fiber yengilazi, ukukhiqizwa kwe-basalt fiber izinto zokusetshenziswa zingokwemvelo futhi zenziwe ngomumo.
Eminyakeni yamuva nje, kuye kwenziwa umsebenzi omningi wokucwaninga ukuze kuhlolwe ama-ores afanele ukukhiqizwa kwezinto ezingavuthiwe ze-basalt fibre eqhubekayo, ikakhulukazi ukukhiqizwa kwemicu ye-basalt enezici ezibekiwe (njengamandla emishini, ukuzinza kwamakhemikhali nokushisa, ukufakwa kukagesi kagesi; njll.), ama-ore athile kufanele asetshenziswe Ukwakheka kwamakhemikhali kanye nezakhiwo ze-fiber.Isibonelo: ububanzi bokwakheka kwamakhemikhali e-ore asetshenziswa ekukhiqizeni i-basalt fiber eqhubekayo kuboniswa etafuleni.
| Ukwakheka kwamakhemikhali | SiO2 | Al2O3 | Fe2O3 | I-CaO | MgO | I-TiO2 | Na2O | Okunye ukungcola |
| Okuncane% | 45 | 12 | 5 | 4 | 3 | 0.9 | 2.5 | 2.0 |
| Ubuningi% | 60 | 19 | 15 | 12 | 7 | 2.0 | 6.0 | 3.5 |
Imvelo inikeze ukusetshenziswa kwamandla okuyinhloko kwe-basalt ore.Ngaphansi kwezimo zemvelo, i-basalt ore ithola ukucebisa, i-homogenization yezingxenye zamakhemikhali futhi incibilike ekujuleni komhlaba.Ngisho nemvelo icabanga ukusunduza i-basalt ore ebusweni bomhlaba ngesimo sezintaba ukuze isetshenziswe abantu.Ngokwezibalo, cishe i-1/3 yezintaba yakhiwe nge-basalt.
Ngokusho kwedatha yokuhlaziya yokwakheka kwamakhemikhali e-basalt ore, izinto zokusetshenziswa ze-basalt zitholakala cishe ezweni lonke, futhi intengo ingu-20 yuan/ton, futhi izindleko zezinto ezingavuthiwe zinganakwa ezindlekweni zokukhiqiza ze-basalt fiber.Kunezindawo zezimayini ezifanele ukukhiqizwa okuqhubekayo kwe-basalt fiber ezifundazweni eziningi zaseChina, njengalezi: ezine, i-Heilongjiang, i-Yunnan, i-Zhejiang, i-Hubei, i-Hainan Island, i-Taiwan nezinye izifundazwe, ezinye zazo ezikhiqize i-basalt fiber eqhubekayo emishini yokuhlola yezimboni.Ama-basalt aseShayina ahlukile kuma-ore aseYurophu.Ngokombono we-geological, ama-basalt ore aseShayina "asemancane", futhi awanazo izici ezihluke kakhulu, okungukuthi, okuthiwa izibazi ze-ore zangempela.Ngokuhlaziywa kwezifundazwe zaseShayina ezifana neSichuan, Heilongjiang, Yunnan, Zhejiang, neHubei, ucwaningo lwensimbi ye-basalt phakathi nendawo ephansi yoMfula iYangtze, iHainan nezinye izifunda kukhombisa ukuthi alikho idwala langempela kulawa ma-basalt ore. , futhi kunezendlalelo ezithile ezijwayelekile ze-iron oxide eziphuzi ngaphezulu.Lokhu kunenzuzo kakhulu ekukhiqizeni okuqhubekayo kwe-basalt fiber, futhi intengo yempahla eluhlaza kanye nezindleko zokucubungula ziphansi.
I-Basalt iyi-silicate engaphili.Iye yashiswa yizintaba-mlilo nasezithandweni zomlilo, kusukela emadwaleni aqinile kuya emiculweni ethambile, izikali ezilula, nezinsimbi eziqinile.Indaba inokumelana nokushisa okuphezulu (> 880C) nokumelana nokushisa okuphansi (<-200C) , ukuguquguquka okuphansi kwe-thermal (ukushisa ukushisa), ukufakwa komsindo, i-flame retardant, i-insulation, ukumuncwa umswakama ophansi, ukumelana nokugqwala, ukumelana nemisebe, amandla amakhulu okuphuka, ukunwebeka okuphansi, i-modulus enwebekayo ephezulu, isisindo esilula nokunye ukusebenza okuhle kakhulu nokusebenza okuhle kakhulu kokucubungula, Kuyimpahla entsha ngokuphelele: ayikhiqizi izinto ezinobuthi enqubweni evamile yokukhiqiza nokucubungula, futhi ayinawo igesi emoshayo, amanzi amoshiwe, kanye nemfucuza. ukukhishwa kwezinsalela, ngakho-ke kubizwa ngokuthi “impahla yezimboni eluhlaza nezinto ezintsha” ezingangcolisi ekhulwini lama-21.
Uma kuqhathaniswa ne-glass fiber, esetshenziswa kabanzi ekwakhiweni, embonini yamakhemikhali nakwezinye izimboni, kusobala ukuthi i-basalt fiber kanye nezinto zayo eziyinhlanganisela zinamandla amakhulu emishini, izakhiwo ezinhle zomzimba namakhemikhali, futhi zingasetshenziswa ukwenza imikhiqizo ephezulu.Uma kuqhathaniswa nezinye izinto, ukusebenza kwawo konke kokubili kuyaqhathaniswa.Ezinye izakhiwo ze-basalt fibre zingcono kune-carbon fiber, futhi izindleko zayo zingaphansi kwengxenye eyodwa kweshumi ye-carbon fiber ngokusho kwentengo yemakethe yamanje.Ngakho-ke, i-basalt fiber iyifayibha entsha enezindleko eziphansi, ukusebenza okuphezulu kanye nokuhlanzeka okuhle ngemuva kwe-carbon fiber, i-aramid fiber kanye ne-polyethylene fiber.I-United States Basalt Continuous Fiber Industry Alliance yaveza: “I-Basalt continuous fiber ithatha indawo ye-carbon fibre enezindleko eziphansi futhi inochungechunge lwezakhiwo ezinhle kakhulu.Okubaluleke kakhulu, ngoba ithathwe ku-ore yemvelo ngaphandle kwezithasiselo, iwukuphela kokungcoliswa okungekona kwemvelo nokungenabuthi.Imikhiqizo yengilazi eluhlaza nenempilo ene-carcinogenic inesidingo esibanzi semakethe kanye nokusetshenziswa kwangaphambilini”
I-Basalt ore ibekwe phezu komhlaba izigidi zeminyaka futhi ibhekene nezimo zezulu ezahlukahlukene.I-Basalt ore ingenye yensimbi enamandla kakhulu ye-silicate.Amafayibha enziwe nge-basalt anamandla emvelo nokuzinza ngokumelene nemidiya ebolayo.Ihlala isikhathi eside, i-insulating kagesi, i-basalt ore iyimpahla eluhlaza ehlanzekile yemvelo futhi enobungani bemvelo.
