nkhani

In a broad sense, our understanding of glass fiber has always been that it is an inorganic non-metallic material, but with the deepening of research, we know that there are actually many types of glass fibers, and they have excellent performance, and there ndizabwino kwambiri. Mwachitsanzo, mphamvu zake zimayenda makamaka, ndipo kukana kwa kutentha kwake komanso kutupa kwake palinso zabwino. Ndizowona kuti palibe chilichonse changwiro, ndipo fiber galasi ilinso ndi zophophonya zomwe sizinganyalanyazidwe, ndiye kuti, sizimavale-osavala komanso amakonda kusokonezeka. Chifukwa chake, pakugwiritsa ntchito, tiyenera kugwiritsa ntchito mphamvu zathu ndikupewa zofooka zathu.

Zopangira zitsamba za galasi ndizosavuta kupeza, makamaka zigalasi zakale kapena galasi. Chitsamba chagalasi chili bwino kwambiri, ndipo zowonera zopitilira 20 palimodzi ndizofanana ndi makulidwe a tsitsi. Fiber galasi imatha kugwiritsidwa ntchito ngati zinthu zolimbitsa thupi m'magawo ophatikizika. Chifukwa cha zofufuza za kafukufuku wamagalasi m'zaka zaposachedwa, imagwira ntchito yofunika kwambiri popanga ndi moyo. Nkhani zingapo zotsatirazi zimafotokoza za kupanga ndi kugwiritsa ntchito kalasi yagalasi. Nkhaniyi imabweretsa katundu, zigawo zikuluzikulu, zifukwa zazikulu, komanso gulu lamitundu ya galasi. Zolemba zochepa zotsatirazi zifotokoza njira yake yopanga, chitetezo cha chitetezo, chitetezo chachikulu, chitetezo cha chitetezo, mafakitale ndi chitukuko chikufotokozedwa.

Inkati

1.1 miliri ya zitsamba

Chinthu china chabwino kwambiri cha fiber galasi ndi mphamvu yake yayitali, yomwe imatha kufikira 6.9g / d mu State State ndi 5.8g / d mu chinyowa. Choyipa chotere chimapangitsa kuti fibe ya galasi nthawi zambiri itha kugwiritsidwa ntchito papadziko lonse lapansi ngati zolimbikitsa. Ili ndi kachulukidwe cha 2.54. Phazi galasi limakhalanso kutentha kwambiri, ndipo imasunga malo ake a 300 ° C. Firberglass nthawi zina imagwiritsidwanso ntchito ngati kutentha komanso zinthu zotchinga, chifukwa cha magetsi ogwiritsa ntchito zamagetsi komanso kulephera kwake kunyamula mosavuta.

1.2 Zosakaniza zazikulu

Kuphatikizika kwa galasi fiber ndi zovuta. Nthawi zambiri, zigawo zikuluzikulu zomwe zimadziwika ndi aliyense ndi silika, magnesium oxide, boron oxide, aluminiyamu oxide, calcium oxide ndi zina zotero. Maonsowa a zodzitchinga galasi ndi pafupifupi 10 microns, yomwe ikufanana ndi 1/10 ya tsitsi la tsitsi. Mtolo uliwonse wa ulusi umapangidwa ndi zowonera zikwizikwi. Njira yojambulayo ndi yosiyana pang'ono. Nthawi zambiri, zomwe zili mu silika mu maakaunti agalasi a 50% mpaka 65%. Mphamvu yakuwoneka ya ulusi wamagalasi okhala ndi ma oxide oxide oposa 20% ali ndi ulusi wagalasi kwambiri, pomwe ma aluminiyamu osungira magalasi aulere nthawi zambiri amakhala pafupifupi 15%. Ngati mukufuna kupanga chiberekero chagalasi kukhala ndi modulus yokulirapo, muyenera kuonetsetsa kuti zomwe zimapezeka kwa magnesium oxide ndi wamkulu kuposa 10%. Chifukwa cha galasi lagalasi yokhala ndi ferric yochepa ya Ferride, kuzunzidwa kwake kuphulika kwakonzedwa ku madigiri osiyanasiyana.

Mawonekedwe Aakulu

1.3.1 Zopangira ndi mapulogalamu ndi mapulogalamu

Poyerekeza ndi ulusi wa itoric, zinthu za ulusi wagalasi ndipamwamba kwambiri. Zimakhala zovuta kwambiri kuyika, kusagwirizana ndi kutentha, kutentha kokhazikika, khola, komanso kutchinga. Koma zimakhala zopanda pake ndipo zimaswa bwino kukana. Ankakonda kupanga pulasitiki kapena kugwiritsidwa ntchito polimbikitsa rabara, monga chiberekero cholimbitsa kwambiri

(1) Mphamvu zake zowoneka bwino kuposa zinthu zina, koma malo okwezeka ndi ochepa kwambiri.

(2) Kugwirizana kotsekedwa ndikoyenera kwambiri.

.

.

(5) Sizovuta kuyamwa madzi.

(6) Kusagwirizana ndi kutentha komanso khola mwachilengedwe, sikosavuta kuchitira.

.

(8) Itha kupatsa kuwala.

(9) Chifukwa zinthuzo ndizosavuta kupeza, mtengo wake siokwera mtengo.

(10) Kutentha kwambiri, m'malo motentha, kumasungunuka kukhala mikanda yamadzi.

1.4

Malinga ndi miyezo yosiyanasiyana ya kagawika, fiberi galasi imatha kugawidwa kukhala mitundu yambiri. Malinga ndi mawonekedwe osiyanasiyana ndi kutalika kwake, itha kugawidwa m'mitundu itatu: ulusi wopitilira, fiben thonje ndi ulusi wokhazikika. Malinga ndi zigawo zosiyanasiyana, monga alkali okhutira, zitha kugawidwa m'mitundu itatu: Alkali-Friber Walder, alkali-alkali galasi lagalasi.

1.5 kupanga zida zophika

Popanga mafakitale, kuti atulutse fiber galasi, timafunikira alumina, mchenga wa quartz, ma doric acid, fluoric algar, mbiti ya glatin, etc.

Njira Yopanga 1.6

Njira zopangira mafakitale zimatha kugawidwa m'magulu awiri: imodzi ikusungunuka galasi yoyamba yoyamba, kenako ndikupanga zowoneka bwino kapena zowoneka bwino. Kenako, amatenthedwa ndikusungunuka m'njira zosiyanasiyana kuti mupange ulusi wabwino kwambiri wa 3-80 μm. Mtundu wina umasungunukanso kapu yoyamba, koma imatulutsa ulusi wamagalasi m'malo mwa ndodo kapena magawo. Chitsanzo chake chinakokedwa kudzera mu platinamu ya alloy pogwiritsa ntchito njira yojambulira. Zolemba zomwe zimatchedwa kuti zikuyenda mosalekeza. Ngati ulusiwo wakokedwa chifukwa chodzigudubuza, zomwe zikuchitika zimatchedwa kuti ulusi wosakhazikika, wotchedwanso ulusi wamagalasi, komanso ulusi wopingasa.

1.7 grading

Malinga ndi kapangidwe kake, kugwiritsa ntchito ndi katundu wa fiber galasi, imagawika m'masukulu osiyanasiyana. Malumu agalasi omwe achita malonda padziko lonse lapansi ali motere:

1.7.1 e-Glasi

Ndigalasi yobowola, yomwe imatchedwanso magalasi aulere a Alkali mu moyo watsiku ndi tsiku. Chifukwa cha zabwino zake zambiri, ndi omwe amagwiritsidwa ntchito kwambiri. Pakadali pano ndi zomwe zimagwiritsidwa ntchito kwambiri, ngakhale zimagwiritsidwa ntchito kwambiri, komanso zimakhalanso ndi zophophonya zosapepuka. Zimakhudzana mosavuta ndi mchere wopanda mafuta, motero ndizovuta kusunga m'malo acidic.

1.7.2 c-glat

Mukupanga, imatchedwanso galasi lalkali, lomwe lili ndi mankhwala osokoneza bongo komanso kukana kwabwino acid. Choyipa chake ndikuti mphamvu yamakina siyikhala yokwera ndipo magwiridwe amagetsi ndi osauka. Malo osiyanasiyana amakhala ndi miyezo yosiyanasiyana. M'makampani agalasi agalasi agalasi, palibe a boron chinthu champhamvu cha alkali. Koma mu malonda achilendo agalasi agalasi, zomwe zimapanga ndi galasi la alkali miliri yokhala ndi Boron. Osangokhala zomwe zili zosiyana, komanso gawo lomwe limachitika ndi magalasi apakatikati-alkali kunyumba ndi akunja ndi osiyananso. Masamu agalasi agalasi ndi ndodo zagalasi zopangidwa kunja zimapangidwa ndi galasi la Alkali. Popanga, galasi lalkali limagwiranso ntchito ku phulusa. M'dziko langa, cholinga chake ndikugwiritsidwa ntchito kwambiri chifukwa cha mtengo wake wotsika kwambiri, ndipo umagwira ntchito kulikonse mu nsalu yokulunga ndi zosefera.

Ndodo ya fiberglass

1.7.3 fiber galasi lagalasi

Popanga, anthu amachitcha galasi lalikulu-lalkali, lomwe ndi lagalasi la sodium, koma chifukwa cha kukana kwa madzi, sikupangidwa ngati fiber galasi.

1.7.4 fiberglass d galasi

Amadziwikanso galasi laideleler ndipo nthawi zambiri amakhala ndi zopangira zazikulu zopangira ma piglective.

1.7.5 galasi la chinyezi

Mphamvu yake ndi 1/4 yayikulu kuposa fiberi ya e-glag, ndi soluciostis modlus ndizokwera kuposa fiber. Chifukwa cha zabwino zake, ziyenera kugwiritsidwa ntchito kwambiri, koma chifukwa cha mtengo wake wokwera, pakadali pano zimagwiritsidwanso ntchito m'minda ina yofunika, monga gulu lankhondo, Aenthor.

1.7.5 galasi fiber galasi

Amatchedwanso alkali-chiberekero chagalasi, chomwe ndi fiber yoyera ndipo imagwiritsidwa ntchito ngati chinthu cholimbikitsa mu konkriti yolimbikitsira mitsuko. Panthawi zina, imatha kusintha chitsulo ndi asbestos.

1.7.6 galasi fiber e -ro

Ndi galasi lopanda ma boron-free ndi alkali. Chifukwa chakuti madzi ake akugwirizana ndi nthawi pafupifupi 10 kuposa fiber galasi lalga, amagwiritsidwa ntchito kwambiri popanga zinthu zosagwira madzi. Komanso, kukana kwake acid kumakhala kolimba kwambiri, ndipo amakhala ndi udindo wopangidwa ndi kugwiritsa ntchito mapiri apansi pansi panthaka. Kuphatikiza pa ulusi wofala kwambiri wotchulidwa pamwambapa, asayansi tsopano apanga mtundu watsopano wa fibergalasi. Chifukwa ndi chogulitsa chaulere cha boron, chimakwaniritsa kufunafuna anthu kuteteza chilengedwe. M'zaka zaposachedwa, pali mtundu wina wa ulusi wagalasi womwe ndi wotchuka kwambiri, womwe ndi ulusi wagalasi ndi galasi lagalasi iwiri. Muzogulitsa zagolide zamakono, titha kuzindikira kuti kukhalapo kwake.

1.8 Kuzindikira kwa ulusi wagalasi

Njira yosiyanitsa ulusi wamagalasi ndi wophweka kwambiri, ndiye kuti, ikani ulusi wagalasi m'madzi, kutentha mpaka madzi owiritsa, ndikusunga kwa maola 6-7. Ngati mupeza kuti njira zankhondo ndi kuwonongeka kwa ulusi wagalasi sizingakhale zocheperako, ndi ulusi wa alkali. . Malinga ndi miyezo yosiyanasiyana, pali njira zambiri za gulu lagalasi, zomwe zimagawidwa kuchokera kumayendedwe a kutalika ndi mainchesi, kapangidwe kake, kapangidwe ndi magwiridwe antchito.
