Ni izihe mbaraga zingana za fibre minerval fibre?
Imbaraga zingana za amabuye y'agaciro ya basaltni ingingo igomba gusesengurwa muburyo bwinshi. Icya mbere, ni ngombwa gusobanura ko imbaraga zingana zerekeza ku guhangayika gukabije ibintu bishobora kwihanganira mbere yo kumeneka. Kuri Fibres, iyi gaciro ni hagati2000 MPa na 4800 MPa. Agaciro kihariye katerwa nibintu nkibigize ibikoresho fatizo, umusaruro, na diameter ya fibre.
Kuki? fibreufite imbaraga zingana gutya? Ibi bifitanye isano ya hafi na microstructure yabo. Basalt ubwayo ni urutare rwibirunga rufite ibice byingenzi birimo dioxyde ya silicon, oxyde ya aluminium, na okiside ya fer. Nyuma yubushyuhe bwo hejuru bwo gushonga, ibyo bice bigize urwego rukomeza rwimiterere-yimiterere itatu, itanga fibre ikomeye. Gukonjesha byihuse mugihe cya Gukora Fibre inzira ituma molekulari itunganijwe neza, ikarushaho kuzamura imiterere yubukanishi.
Ibintu byihariye bigira ingaruka zikomeye birashobora kurebwa mubice bikurikira:
-
Ibikoresho bito: Ibigize ubutare bwa basalt kuva inkomoko zitandukanye biratandukanye. Mubisanzwe, ibikoresho fatizo birimo dioxyde de silicon iri hagati ya 46% na 52% bitanga fibre n'imbaraga nziza. Ibyunyunyu fer birenze urugero birashobora gutuma imbaraga zigabanuka.
-
Uburyo bwo kubyaza umusaruro: Ubushyuhe bwo gushonga bugenzurwa neza kuri 1400-1500 ° C. Niba ubushyuhe buri hasi cyane, gushonga kwijimye bizaba hejuru, gushushanya bigoye; niba ari hejuru cyane, irashobora gutera ibice guhindagurika. Igishushanyo cyihuta nacyo cyingenzi; niba byihuta cyane, diameter ya fibre izaba idahwanye.
-
Diameter ya Fibre: Fibre hamwe na diameter isanzwe ya microni 9-13 ifite imbaraga zizwi cyane. Nuburyo bwiza bworoshye fibre ifite imbaraga zisumba izindi, zikunda kwibasirwa numusaruro nyirizina.
-
Kuvura Ubuso: Ibicuruzwa bimwe bivurwa hamwe nubuso, byombi birinda fibre kandi bishobora kugira ingaruka runaka kubububasha bwayo.
Mubikorwa bifatika, uburyo bwo guhitamo iburyo fibre? Ibi bigomba kugenwa hashingiwe kumikoreshereze yihariye. Kubisabwa bisaba imbaraga nyinshi, nkibikoresho byubaka byubaka, birasabwa guhitamo ibicuruzwa bifite imbaraga zizina hejuru ya 4000 MPa. Kubikorwa rusange, nkibikoresho byo kubika, imbaraga zisabwa zirashobora kugabanuka muburyo bukwiye. Ni ngombwa kumenya ko ibizamini bya laboratoire bishobora gutandukana nibikorwa mubikorwa nyabyo. Ibintu nkubushyuhe, ubushuhe, nuburemere bwigihe kirekire birashobora kugira ingaruka kumikorere ya fibre.
Kubyerekeye kugereranya fibre imbaraga hamwe nizindi fibre, ingingo nke zisanzwe zishobora gukoreshwa kugirango zerekanwe: imbaraga zingana za fibre isanzwe ya E-ikirahure ni MPa 3000, fibre S-ikirahure irashobora kugera kuri MPa 4500, naho fibre ya karubone iri hagati ya 3000-7000 MPa. Uhereye kuri iyi ngingo, imbaraga za fibre ya basalt iri murwego rwo hagati-hejuru. Nyamara, ibyiza byayo biri mubiciro byibikoresho fatizo kandi birwanya ubushyuhe bwo hejuru hamwe nubushakashatsi bwimiti.
Kubijyanye no kugenzura ubuziranenge, uburyo bumwe bwo gupima fibre tensile ikoreshwa muburyo bwo kumenya imbaraga. Mugihe cyo kwipimisha, hagomba kwitonderwa byumwihariko gahunda yo gutegura icyitegererezo kugirango wirinde kwinjiza inenge bitewe nibintu byabantu. Inganda zinganda zisaba gupima byibura fibre 50 no gufata impuzandengo nkibisubizo byanyuma. Kubera ko hari ubushishozi runaka mumbaraga za fibre, uyu mubare wibizamini urashobora kwemeza kwizerwa ryamakuru.
Kubyerekeranye niterambere ryigihe kizaza, abashakashatsi baragerageza kurushaho kunoza imbaraga za fibre fibre binyuze muburyo nka nanomodifike hamwe no kuzunguruka. Kurugero, kongeramo umubare muto wibigize bidasanzwe kubikoresho fatizo birashobora guhindura ibintu bishonga; ukoresheje electromagnetic yumurima wafashijwe gushushanya tekinoroji irashobora kunoza uburinganire bwimiterere ya fibre. Nubwo izi nzira nshya ziracyari muri laboratoire, zerekana ibyiza byo gusaba.
Kugumana imbaraga zingutu nabyo bireba abakoresha. Ubushakashatsi bwakozwe bwerekana ko ahantu humye ku bushyuhe bwicyumba, igipimo cyo kugumana imbaraga za ubuziranenge bwa basalt fibre irashobora kugera kuri 90% nyuma yimyaka icumi. Nyamara, mubushyuhe bwo hejuru cyangwa ibidukikije byangirika, agaciro kazagabanuka. Kubwibyo, mubikorwa byubwubatsi nyabyo, ingamba zikwiye zo kurinda zigomba gutoranywa hashingiwe ku bidukikije.
Hanyuma, bigomba kwibutswa ko nubwo fibre ya basalt ifite imbaraga zingana cyane, imikorere ihuza imiyoboro nayo igomba kwitabwaho mubicuruzwa byihariye. Kurugero, mubikorwa bifatika byo gushimangira, imbaraga zo guhuza fibre na matrix akenshi ni ngombwa kuruta imbaraga za fibre ubwayo. Ibi bigomba kunozwa binyuze mubuvuzi bwo hejuru cyangwa hiyongereyeho guhuza ibintu.
