Zosiyanasiyana zamtundu wa fiberglass
Fiberglass ndi chinthu chabwino kwambiri chopanda zitsulo.Galasi CHIKWANGWANIndi mtundu wachilengedwe wachilengedwe wopanda zitsulo ore monga leucolite, pyrophyllite, kaolin, mchenga wa quartz, miyala yamchere, etc. Ulusi wapamwamba kwambiri wamtundu wamtundu wamtundu wa ma microns angapo mpaka ma microns 20, omwe ndi ofanana ndi 1. / 20-1/5 ya tsitsi.
Pali mitundu yambiri ya magalasi opangira magalasi, omwe ali oyenera pazochitika zosiyanasiyana.Ulusi wagalasi ukhoza kugawidwa m'mitundu yosiyanasiyana molingana ndi kapangidwe kake, monga osakhala alkali, sing'anga-alkali, alkali yapamwamba, yamphamvu kwambiri, yopanda boron komanso yopanda alkali, etc. Ntchitoyi ndi yosiyana, ndipo imagwiritsidwa ntchito. m'madera osiyanasiyana malinga ndi machitidwe ake.Mwachitsanzo, ulusi wagalasi wokhala ndi alkali chitsulo okusayidi wochepera 0.8%.ulusi wagalasi wopanda alkali, omwe ali ndi magetsi abwino otsekemera komanso makina, koma osakanizidwa ndi asidi, choncho amagwiritsidwa ntchito kwambiri pazithunzi zomwe zimafuna kutsekemera kwa magetsi kapena FRP;Zomwe zili 11.9% -16.4% ndi za sing'anga-alkali galasi CHIKWANGWANI, amene ali amphamvu asidi kukana koma osauka magetsi ntchito, ndi mphamvu mawotchi ake ndi otsika kuposa sanali alkali galasi CHIKWANGWANI.Amagwiritsidwa ntchito kunja kwa zida zomangirira za asphalt zomwe zimakhala ndi mphamvu zochepa zamakina;Magalasi apamwamba kwambiri amakhala ndi zirconia, zomwe zimakhala ndi mphamvu zowonongeka, zotsika mtengo komanso zotsika mtengo, choncho zimagwiritsidwa ntchito makamaka pazinthu zankhondo;kuonjezera apo, ulusi wa alkali wapamwamba sugwira ntchito bwino ndipo wathetsedwa.

Ulusi wagalasi amathanso kuphatikizidwa ndi zida zina kuti apange zida zophatikizika zamagalasi, zomwe FRP ndiye chinthu chachikulu.Ulusi wagalasi ukhoza kupangidwa ndi utomoni kuti upange pulasitiki wolimbitsa magalasi (FRP), kapena kuwonjezera phula kuti apange phula lolimba lagalasi.Chifukwa cha mitundu yayikulu yazinthu zomwe zitha kupangidwa, pakali pano palibe gulu lodziwika bwino la zida zophatikizika zamagalasi.Malinga ndi kafukufuku wa Qianzhan Industry Research Institute, FRP imapanga pafupifupi 75% ya msika wa zida zagalasi zopangidwa ndi magalasi ndi zinthu, zomwe zimakhala ndi udindo waukulu.Chifukwa chake, timatenga FRP ngati chitsanzo kuti tiwunikenso ubwino wa magalasi a fiber composites.
FRP ndi chinthu china chomwe chili ndi magwiridwe antchito abwino kwambiri.FRP ndi chinthu chophatikizika chokhala ndi utomoni wopangira ngati matrix ndi magalasi fiber ndizinthu za fiberglass(mphasa, nsalu, lamba, etc.) monga zolimbitsa.FRP imadziwika ndi dzina lake kuchokera ku mawonekedwe ake ngati galasi komanso kulimba kwake ngati chitsulo.Poyerekeza ndi chitsulo chodziwika bwino pomanga, kachulukidwe kachitsulo ndi 7.85 × 103kg/m3, ndipo kachulukidwe ka FRP ndi 1.9 × 103kg/m3, yomwe ndi yopepuka kuposa chitsulo, ndipo mphamvu yake yeniyeni ndi kukana kwa dzimbiri kumaposa chitsulo;poyerekeza ndi aloyi zotayidwa, matenthedwe madutsidwe a aloyi zotayidwa ndi 203.5W/m.℃, ndi madutsidwe matenthedwe FRP ndi 0.3W/m.℃.Kutentha kwamafuta a FRP ndikwabwinoko, ndipo moyo wautumiki wa FRP ndi zaka 50, zomwe zimawirikiza kawiri kuposa aloyi ya aluminiyamu.Chifukwa chakuchita bwino kwambiri, FRP, m'malo mwa zida zachikhalidwe, imagwiritsidwa ntchito kwambiri pomanga, njanji, ndege, malo osungiramo ma yacht ndi mafakitale ena.

Zopangira zopangira magalasi zam'mwamba ndizosavuta kuzipeza, ndipo zopangira kumunsi ndizochulukira.Zopangira zopangira magalasi opangira magalasi ndizomwe zimakhala zopangira mchere komanso zopangira mankhwala, kuphatikiza pyrophyllite, kaolin, mchenga wa quartz, miyala yamchere, ndi zina zambiri, zomwe ndi mchere wokhala ndi nkhokwe zazikulu ku China, ndipo ndizovuta kupeza;mphamvu zomwe zimagwiritsidwa ntchito makamaka ndi magetsi ndi gasi;ntchito zapansi pamtsinje Ndizochuluka, makamaka kuphatikizapo zipangizo zomangira, zoyendetsa, zipangizo zamagetsi, zipangizo zamafakitale, mphamvu ndi chitetezo cha chilengedwe ndi zina.
Glass fiberrekufunikira kwa msika
Kuchokera pakuwona kwakukulu, zikuyembekezeka kuti chiŵerengero cha kukula kwa magalasi ofunikira ku dziko langa ndi kukula kwa GDP chidzakhalabe chokwera kwambiri pakanthawi kochepa.Akuti kumwa magalasi a dziko langa m'zaka 22/23 kudzakhala matani 5.34 miliyoni ndi matani 6 miliyoni, kuwonjezeka kwa 13.2% ndi 12.5% motsatira.
Poganizira kagwiritsidwe ntchito kachulukidwe ka ulusi wamagalasi, zisonyezo zazachuma zapakhomo zimakhalabe ndi tanthauzo pakuweruza kufunikira kwa magalasi am'nyumba.Poganizira: 1) kugwiritsa ntchito magalasi pachaka kwa munthu aliyense kumakhala kotsika kwambiri poyerekeza ndi mayiko otukuka;2) mlingo malowedwe a galasi CHIKWANGWANI m'minda yaikulu ya galasi CHIKWANGWANI ntchito, monga zomangamanga ndi galimoto, ndi otsika kwambiri kuposa mayiko otukuka, ndi zinthu zatsopano Motsogozedwa ndi kukwezeleza mfundo, timakhulupirira kuti chiŵerengero cha dziko lathu Chiwopsezo cha kukula kwa fiber fiber mpaka kukula kwa GDP chikhalabe chokwera pakanthawi kochepa, ndipo chikuyembekezeka kuyandikira msika wokhwima pakanthawi kochepa komanso kwakanthawi.
Zikuyembekezeka kuti chiŵerengero cha kukula kwa chiwongoladzanja cha magalasi a dziko langa ndi kukula kwa GDP chidzakhalabe chokwera kwambiri pakanthawi kochepa.Pansi pamalingaliro osalowerera ndale, akuti chiŵerengero cha kukula kwa magalasi amafunidwa ndi kukula kwa GDP mu zaka 22/23 chidzakhala 2.4 ndi 2.4 motsatira, chofanana ndi galasi fiber.Kukula kwa kufunikira kwa fiber kunali 13.2% ndi 12.5% motsatana, ndipo kugwiritsa ntchito magalasi a fiber kunali 5.34 ndi matani 6 miliyoni motsatana.
