Ibyiza 10 Byiza bya Fibre Basalt

Fibre: Ibyiza 10 Byambere

Fibreni fibre ikomeza ya fibre ikozwe mubisanzwe Urutare rwa Basalt. Urutare rushonga kuri 1450 ° C-1500 ° C hanyuma rugakururwa binyuze muri platine-rhodium alloy bushing ku muvuduko mwinshi. Fibre nziza ya basalt isanzwe yijimye. Nubwoko bushya bwa organic organique, butangiza ibidukikije, fibre ikora cyane igizwe na okiside nka dioxyde de silicon, oxyde ya aluminium, calcium oxyde, magnesium oxyde, oxyde de fer, na dioxyde de titanium. Fibre ikomeza ya Basalt ntabwo ifite imbaraga nyinshi gusa ahubwo ifite nubwiza buhebuje nko kubika amashanyarazi, kurwanya ruswa, no kurwanya ubushyuhe bwinshi. Byongeye kandi, uburyo bwo kuyibyaza umusaruro butanga imyanda mike n’umwanda w’ibidukikije, kandi ibicuruzwa byajugunywe birashobora kwangirika bisanzwe nta byangiritse, bikabigira ikintu kibisi kandi cyangiza ibidukikije. Ubushinwa bwashyize ku rutonde fibre ya basalt nk'imwe mu mibiri ine y'ingenzi igamije iterambere (hamwe na fibre karubone, aramide, na polyethylene ifite uburemere buke cyane) kandi imaze kugera ku nganda. Fibre ikomeza ya basalt ubu ikoreshwa cyane muri fibre-yongerewe imbaraga, ibikoresho byo guterana amagambo, kubaka ubwato, inganda zitwara ibinyabiziga, hamwe nubushyuhe bwo hejuru hamwe nibisabwa kurinda.

1. Ibikoresho Byinshi Byinshi

   Fibre ya Basalt ikozwe mu rutare rwa basalt, iboneka ku bwinshi ku isi no ku kwezi. Ibi bituma ibiciro byibanze bigabanuka.

2. Ibikoresho byangiza ibidukikije

   Basalt urutare ni ibintu bisanzwe. Ibikorwa byayo ntibishobora kurekura boron cyangwa ibindi byuma bya alkali, bityo umukungugu numwotsi ntabwo birimo ibintu byangiza kandi ntibihumanya ikirere. Igicuruzwa nacyo gifite igihe kirekire cyo kubaho, bigatuma igiciro gito, gikora cyane, kandi gisukuye ibintu bishya byatsi.

3. Ubushyuhe bwo hejuru no Kurwanya Amazi

   Gukomeza fibre irashobora gukora mubushuhe bugari bwa -269 ° C gushika kuri 700 ° C (hamwe nokworoshya 960 ° C). Ibi biruta gfibre (-60 ° C kugeza kuri 450 ° C) na fibre ya karubone (max 500 ° C). Ikigaragara ni uko fibre ya basalt igumana 80% yingufu zumwimerere nyuma yo gukora kuri 600 ° C kandi ntigabanuka kuri 860 ° C. Ikomeza kandi imbaraga nyinshi nyuma yo guhura n’amazi ashyushye 70 ° C.

4. Ubwiza buhebuje bwimiti no kurwanya ruswa

   Fibre ya Basalt irimo ibice nka K₂O, MgO, na TiO₂, biteza imbere cyane kurwanya imiti yangiza amazi. Ifite imiti irenze fibre yibirahure, cyane cyane muri alkaline na acide. Fibre ya Basalt yerekana nubwo irwanya alkali kwangirika kwuzuye Ca (OH) ₂ ibisubizo na sima.

5. Modulus yo hejuru ya Elastike nimbaraga za Tensile

   Modulus ya Basalt fibre (9100-11000 kg / mm) irarenze iy'ibikoresho bya E-ibirahure, asibesitosi, aramide, polypropilene, na fibre silicon. Imbaraga zayo zingana (3800-4800 MPa) iruta iy'ibikoresho binini bikurura karubone, aramid, fibre ya PBI, fibre fibre, fibre boron, na alumina fibre, kandi bigereranywa na S-ibirahuri. Ubucucike bwa 2,65-3.00 g / cm³ hamwe na Mohs ubukana bwa 5-9, butanga imbaraga zo kwihanganira kwambara no gushimangira imbaraga. Imbaraga za mashini zirenze kure fibre naturel na synthique, ikagira ibikoresho byiza byubaka.

6. Imikorere idasanzwe yijwi

   Fibre ikomeza ya basalt ifite amajwi meza hamwe no kwinjiza urusaku. Ijwi ryayo yo kwinjiza amajwi yiyongera cyane hamwe na frequence. Kurugero, ibikoresho bikurura amajwi bikozwe muri fibre ya basalt ya diametre 1-3 mm (hamwe n'ubucucike bwa kg 15 / m³ n'ubugari bwa mm 30) ifite coefficient zo kwinjiza amajwi ya 0.05-0.15 kuri 100-300 Hz, 0.22-0.75 kuri 400-900 Hz, na 0.85-0.93 kuri 1200-7000 Hz.

7. Ibyiza bya Dielectric

   Fibre ikomeza'ingano yubunini ni gahunda yubunini burenze E-ikirahure cya fibre, ikagiha ibintu byiza bya dielectric. Nubwo urutare rwa basalt rurimo hafi 0.2% ya okiside itwara ibintu, kuvura bidasanzwe hamwe nubunini bushobora kugabanya igihombo cya dielectric ku kigero cya 50% ugereranije na fibre yikirahure, kandi nubunini bwayo nabwo buri hejuru.

8. Guhuza Kamere Kamere

   Ikwirakwiza neza kandi ihuza cyane na sima na beto. Kwiyongera kwubushyuhe hamwe no kugabanya ubushyuhe burahoraho, kandi bifite guhangana nikirere cyiza.

9. Ubushuhe buke

   Fibre ya Basalt ifite igipimo cyo kwinjiza amazi kiri munsi ya 0.1%, ikaba iri munsi ya fibre aramide, ubwoya bwamabuye, na asibesitosi.

10. Ubushyuhe buke

    Amashanyarazi ya Basalt fibre yumuriro ni 0.031-0.038 W / m · K, iri munsi ya fibre yamide, fibre ya aluminium silike, E-ikirahure cya fibre, ubwoya bwamabuye, fibre silicon, fibre karubone, nicyuma kitagira umwanda.
