Lipoti la kafukufuku wamakampani a Glass fiber: Mtundu wazinthu zophatikizika, kuzungulira ndi kukula zimayenderana

1 Glass fiber composite material model, yogwiritsidwa ntchito pazinthu zosiyanasiyana zachuma za dziko

1.1 Magalasi CHIKWANGWANI - apamwamba ntchito inorganic sanali zitsulo zinthu

Glass CHIKWANGWANI mkulu ntchito zipangizo, osiyanasiyana ntchito.Glass CHIKWANGWANI anabadwa mu 1930s, ndi pyrophyllite, quartz mchenga, miyala yamchere, dolomite, borite, boromite ndi zina zazikulu mchere zopangira ndi boric acid, koloko phulusa ndi zina mankhwala zopangira kupanga inorganic sanali zitsulo zipangizo.Ndi kulemera kopepuka, mphamvu yayikulu, kukana kutentha kwambiri ndi kutsika, kukana kwa dzimbiri, kutchinjiriza kutentha, kuletsa moto, kuyamwa kwamawu, kutsekemera kwamagetsi ndi zinthu zina zabwino kwambiri komanso kuchuluka kwa magwiridwe antchito, ndizinthu zabwino kwambiri zogwirira ntchito komanso zomangamanga.M'zaka zaposachedwapa, galasi CHIKWANGWANI thermoplastic analimbitsa zipangizo zakula mofulumira, ndi zinthu zatsopano monga galasi CHIKWANGWANI kulimbikitsa zipangizo zomangira, ulusi waufupi ndi ulusi wautali zida mwachindunji analimbitsa zida zakhala mfundo zatsopano za chitukuko cha mafakitale CHIKWANGWANI galasi.Kugwiritsa ntchito magalasi opangira magalasi kwakula kuchokera kumagawo azigawo zamafakitale monga zida zomangira, zida zamagetsi, zoyendera njanji, petrochemical, kupanga magalimoto kupita kumadera omwe akubwera monga mlengalenga, kupanga mphamvu yamphepo, kusefera ndi kuchotsa fumbi, uinjiniya wa chilengedwe, ndi uinjiniya wanyanja.

Mfundo yamagulu ndi yosiyana, ndipo mitundu ya fiber fiber ndi yosiyana.Malinga ndi mawonekedwe osiyanasiyana azinthu ndi kupanga, zinthu zamagalasi zamagalasi zamakampani zitha kugawidwa m'magulu anayi, ulusi wopota, wopota, zinthu zozungulira, zopangidwa ndi ulusi wa spun.Kuyendayenda kumaphatikizapo ulusi wolunjika, ulusi wa ply ndi ulusi wodula;Ulusi wabwino ukhoza kugawidwa mu ulusi wopota woyambirira, ulusi wopota kawiri, ulusi wochuluka ndi ulusi wolunjika.Zogulitsa zoyendayenda zimaphatikizapo nsalu zambiri za axial, plaid nsalu, kumva;Zopangira ulusi wabwino zimaphatikizapo nsalu zamagetsi ndi nsalu zamakampani.Kutengera ndi mitundu yosiyanasiyana ya utomoni wa matrix wofananira, imatha kugawidwa m'magulu awiri agalasi la thermosetting ndi thermoplastic glass fiber.

Utoto wa matrix wofananira ndi utomoni wagalasi wa utomoni wa thermosetting ndi utomoni wa phenolic, urea-formaldehyde resin, epoxy resin, unsaturated resin, polyurethane ndi zina zotero.Thermosetting utomoni ndi mzere kapena nthambi-unyolo polima pamaso kuchiritsa, ndipo pambuyo kutentha machiritso, zomangira mankhwala amapangidwa pakati unyolo molekyulu kukhala mawonekedwe atatu azithunzithunzi maukonde, amene amapangidwa kamodzi ndipo sangathe kutenthedwa kachiwiri.Amagwiritsidwa ntchito makamaka m'minda yomwe imayenera kukwaniritsa kutentha kwa kutentha, kukana kuvala, kutsekemera, kutsekemera kwakukulu ndi zotsatira zina, monga masamba a mphepo ndi matabwa ozungulira.

Utoto wa matrix wofananira utomoni wagalasi wa utomoni wa thermoplastic makamaka polyolefin, polyamide, poliyesitala, polycarbonate, polyformaldehyde ndi zina zotero.Thermoplastic utomoni ndi mkulu maselo kulemera olimba kutentha firiji, ndi liniya kapena ochepa nthambi unyolo polima, palibe mtanda kulumikiza mamolekyu, kokha ndi van der Waals mphamvu kapena hydrogen chomangira kukopana.Pakuumba, utomoni wa thermoplastic umafewetsa ndikutuluka pambuyo pakutentha kwamphamvu, popanda kuphatikizika kwa mankhwala, ndipo ukhoza kupangidwa mu nkhungu, ndipo zinthu zomwe zimakhala ndi mawonekedwe ofunikira zimatha kuzizira.Amagwiritsidwa ntchito kwambiri kuti akwaniritse kulimba, kukana dzimbiri, kukana kutopa ndi zotsatira zina zamunda, monga kupanga magalimoto, zida zapakhomo, zida zamagetsi, zomangira.Pambuyo pakupanga magalasi a thermoplastic fiber composite atachiritsidwa ndikukhazikika, amatha kufikira madziwo potenthetsanso ndipo amatha kubwezeredwanso bwino.

Mng'anjo wa matanki opangira magalasi ndiye njira yayikulu yojambulira waya yomwe imachotsedwa pang'onopang'ono pamsika.Pali njira ziwiri zazikulu zopangira magalasi opangira magalasi, omwe amagawidwa m'mapangidwe awiri - njira yojambulira mawaya a crucible ndi imodzi yojambula - njira yojambulira waya wa dziwe.Njira yojambulira mawaya a Crucible: njirayi ndi yovuta, zopangira magalasi zimasungunuka mu mpira wagalasi pa kutentha kwakukulu, ndiyeno mpira wa galasi umasungunuka kawiri, ndipo kujambula kwa waya wothamanga kwambiri kumapangidwa kukhala ulusi wa galasi.Njira yojambulira waya wa dziwe: zida zopangira monga pyrophylla zimasungunuka mu ng'anjo kuti zipangitse yankho lagalasi, ndipo thovulo limachotsedwa ndikusamutsidwa kupita ku mbale yotulutsa porous kudzera munjira, ndipo ulusi wagalasi umakokedwa mwachangu.Mng'anjoyo imatha kulumikiza mbale zochucha mazana ambiri kudzera munjira zingapo nthawi imodzi.Poyerekeza ndi njira yojambulira mawaya a crucible, njira yojambulira mawaya a dziwe ndi yosavuta, yopulumutsa mphamvu ndi kuchepetsa kumwa, kukhazikika kokhazikika, kuchita bwino kwambiri komanso zokolola zambiri, ndipo ndiyosavuta kupanga zazikulu zokha zokha, zomwe zakhala zopanga padziko lonse lapansi. ndondomeko, ndi galasi fiber dimension yopangidwa ndi ndondomekoyi imakhala yoposa 90% ya zomwe zimatulutsidwa padziko lonse lapansi.
