Kusanthula kwa Basalt Fiber Technology
Zida Zopangira ndi Njira Yopangira
The zopangira kwa basalt fiber ndi phiri la basalt rock. Zake Chemical kapangidwe kake ndi silicon dioxide ndi aluminium oxide, yophatikizidwa ndi oxides yachitsulo, calcium, ndi ena. Pambuyo pophwanyidwa ndi kuyeretsa, ore amalowetsedwa mu ng'anjo yosungunuka, momwe amasungunuka kukhala magma ofanana ndi kutentha kwakukulu kwa kuzungulira. 1500 ° C, ndiyeno kukokedwa mu ulusi mosalekeza kudzera mu platinamu-rhodium alloy spinneret.
Kuyelekeza ndi Glass Fiber,basalt fiber imathetsa ndondomeko ya batching ndipo imagwiritsa ntchito chinthu chimodzi chokha. Poyerekeza ndi njira yovuta ya carbonization ya carbon fiber, yomwe imafuna kalambulabwalo wa organic, kupanga kwake kumakhala kolunjika. Komabe, kusinthasintha kwa kapangidwe ka basalt ore kumatha kukhudza kukhazikika kwa fiber, zomwe zimafunikira kuwunika kozama kwazinthu zopangira.
Zochita Zathupi ndi Chemical
(1) Katundu Wamakina: Mphamvu yamanjenje ya basalt fiber ili pakati pa ulusi wagalasi wamba ndi kaboni fiber, nthawi zambiri kuyambira 3000 mpaka 4800 MPa, yokhala ndi modulus yotanuka pafupifupi 90-110 GPa. Izi ndizopambana kuposa E-glass fiber koma zotsika kuposa high-modulus carbon fiber. Kutalika kwake panthawi yopuma ndi pafupifupi 3%, kusonyeza kulimba mtima.
(2) Kulimbana ndi Kutentha: Kutentha kwa nthawi yayitali ndi -260 ° C mpaka 700 ° C, ndi kutentha kwa nthawi yomweyo mpaka 1000 ° C. Izi ndizopambana kuposa ulusi wambiri wa organic ndi ulusi wagalasi wamba, ulusi woyandikira wa ceramic koma pamtengo wotsika.
(3) Kukana kwa Corrosion: Kukhazikika kwake m'malo a asidi ndi alkali ndikwabwinoko kuposa ulusi wagalasi, makamaka kuwonetsa pafupifupi kusawononga mu pH 2-11, zomwe zimapangitsa kukhala koyenera kumadera ovuta ngati mikhalidwe yonyowa komanso kutsitsi mchere.
(4) Katundu Zina: Ili ndi a otsika matenthedwe ma conductivity (pafupifupi. ), ntchito yabwino yotchinjiriza magetsi, komanso mayamwidwe a chinyezi osakwana .
Kufananiza Magawo Ogwiritsa Ntchito
(1) Kulimbikitsa Zomangamanga: Poyerekeza ndi rebar yachikhalidwe yachitsulo, basalt fiber rebar ndizopepuka komanso zolimbana ndi dzimbiri, zomwe zimapewa vuto la konkriti carbonation, ngakhale mtengo wake woyamba ndi wapamwamba. Poyerekeza ndi carbon fiber rebar, imapereka bwino mtengo-mwachangu.
(2) Kuwala kwa Magalimoto: Muzinthu monga ma brake pads ndi zishango zotentha zotulutsa mpweya, ndizotetezeka ku chilengedwe kuposa asibesitosi ndipo zimachepetsanso kulemera. poyerekeza ndi zipangizo zachitsulo.
(3) Zida Zamagetsi: Imagwiritsidwa ntchito ngati zida zolimbikitsira ma board ozungulira, magwiridwe ake a dielectric ndi apamwamba kuposa magalasi opangira magalasi, ndipo amapewa zovuta zoteteza chizindikiro.
(4) Zosefera: Kukana kwake kutentha kwambiri kumapereka mwayi wochuluka kuposa zosefera zamafuta m'munda wa kusefedwa kwa gasi wotentha kwambiri.
Zolephera Zaukadaulo
(1) Mtengo Wopanga: Mtengo wapano wa basalt fiber ndi pafupifupi nthawi 2-3 kuposa E-glass fiber, makamaka chifukwa cha kusungunuka kwamphamvu kwamphamvu komanso kuvala kwakukulu kwa spinneret. Kupanga kwakukulu kungachepetse izi mpaka pafupifupi 1.5 kuchulukitsa kwa fiber magalasi.
(2) Kuwongolera Njira: Kufanana kwa kusungunula kumakhudza kwambiri kuchuluka kwa fiber, zomwe zimafuna kuwongolera bwino gawo la kutentha ndi liwiro lojambula.
(3) Kusinthasintha kwa Kusintha Kwakuya: Kusankhidwa kwa ma coupling agents omwe amalumikizana ndi ma matrices a utomoni ndikolimba kwambiri kuposa ulusi wagalasi, womwe umafuna kukhathamiritsa kolunjika.
Zochitika Zachitukuko Zamakono
(1) Ukadaulo Woyeretsa Zinthu Zopangira: Kugwiritsa ntchito njira monga kulekanitsa maginito ndi kuyandama kuti muchepetse chitsulo mu ore, potero kumapangitsa kusungunuka kusungunuka.
(2) Kupititsa patsogolo Njira Yosungunuka: Kupanga zida zatsopano zotenthetsera ma electrode kuti muchepetse kugwiritsa ntchito mphamvu pafupifupi poyerekeza ndi ng'anjo zachikale zowotchedwa ndi gasi.
(3) Kusiyanasiyana Kwazinthu: Mitundu yapadera ngati ultra-fine fibers (single filament diameter ) ndipo ulusi wokhala ndi magawo osazungulira apangidwa.
(4) Kubwezeretsanso: Zinyalala ulusi akhoza kuphwanyidwa ndi ntchito ngati zosakaniza mu konkire, kukwaniritsa gwero kufalitsidwa.
Mapeto
Poyerekeza ndi ulusi wina wochita bwino kwambiri, phindu lalikulu la basalt fiber zagona mu dongosolo lake zonse zachilengedwe zopangira komanso magwiridwe antchito abwino. Ngakhale mphamvu zake zodziwika sizokwera kwambiri ngati mpweya wa carbon, komanso kutentha kwake kumakhala kotsika kusiyana ndi ulusi wa ceramic, kuyanjana kwake ndi chilengedwe komanso kutsika mtengo kumapangitsa kuti zisalowe m'malo osiyanasiyana m'mafakitale osiyanasiyana. Ndi kukhathamiritsa kosalekeza kwa njira yopangira, ntchito zake zosiyanasiyana zikuyembekezeka kukulirakulira.
