BFRP Development Dilemma

1 Zovuta zokonzekera

Ubwino wa BF ndi chimodzi mwazinthu zofunika zomwe zimakhudza mtundu wa Mtengo wa BFRP. Komabe, kafukufuku wapano pa BFRP amayang'ana kwambiri kusiyana kwa kukulitsa kwa BF poyerekeza ndi ulusi wina pazakuthupi, komanso kutsimikiza kwazinthu zosiyanasiyana za BFRP pansi pazida zosiyanasiyana. Pali kusowa kwa kafukufuku pa Basalt zigawo, kugawa kwazinthu, njira yopangira BF, katundu wakuthupi ndi wamakina, ndi mawonekedwe akuthupi ndi makina a BFRP kutengera zida zopangira kuchokera kumadera osiyanasiyana. Chifukwa cha kusiyana kwakukulu kwa zigawo za basalt m'madera osiyanasiyana, zidzachititsa kuti kusiyana kwakukulu kwa khalidwe la magulu osiyanasiyana a BF, monga momwe amapangira popanda kusinthidwa kwina kwa gulu la basalt, pogwiritsa ntchito njira zomwezo, zidzachititsa kuti basalt ikhale yosungunuka, yomwe imalepheretsa kubadwa kwa BF yapamwamba kwambiri, yomwe idzakhudza kupanga mapangidwe apamwamba.Mtengo wa BFRP. Pakalipano, chifukwa cha zofooka za ndondomeko ya kukonzekera kwa BF, wothandizira mafilimu omwe amagwiritsidwa ntchito popanga BF amagwiritsidwa ntchito kwambiri popanga mafilimu omwe amagwiritsidwa ntchito popanga ulusi wina; kusungunuka kwapamwamba kwambiri sikumangokhala homogenized, zomwe zimapangitsa kuti ma filaments awonongeke kwambiri; ndi kupanga zoweta za mafakitale BF zambiri ntchito kupanga ang'onoang'ono Crucible Ng'anjo kukwaniritsa kupanga yaikulu maindasitale a zomera ndi zochepa zoletsa ndi yaikulu mafakitale kupanga mkulu-ntchito BF, kuchepetsa linanena bungwe la mkulu-ntchito BF. Chifukwa cha kupanga ndondomeko BF, kuvala ndi kung'ambika mbale kutayikira, ndi kufunika kukonzanso pafupipafupi, mbale kutayikira yaing'ono pafupifupi moyo utumiki wa miyezi 9 okha, ndi mbale kutayikira lalikulu pafupifupi 11 miyezi. Chophimba chotsitsacho chimakhala chopangidwa ndi aloyi ya platinamu, ndipo mtengo wake ndi wokwera, zomwe zimapangitsa kuti pakhale mtengo wokwera wa BF, zomwe zimalepheretsa chitukuko cha BFRP kumsewu wotsika mtengo. Njira yophatikizika ya BF ndi zida zina ndichimodzi mwazinthu zofunika zomwe zimakhudza mtundu wa BFRP. M'kati mwa Mtengo wa BFRP okonzedwa ndi ndondomeko kusanganikirana mwachindunji, mawonekedwe yosalala BF ndi makhalidwe a BF n'zosavuta kuchita ndi zipangizo zina zidzachititsa BF ndi kugwirizana zinthu si kuyandikira, zosavuta achotse ku zinthu, chifukwa Mtengo wa BFRP ntchito kuwongola zotsatira sangathe kufika kuyembekezera, kapena kuchepetsa mphamvu choyambirira cha zinthu ndi chodabwitsa cha kukana madzi. Njira yophatikizira yophatikiza imapanga zida zoyambira za BFRP zolondola kwambiri. Chifukwa chake, kuti mupeze zambiri zapamwamba kwambiri Mtengo wa BFRP, zofunikira za chiŵerengero cha BF ku zosintha zina ndi zipangizo ndi mikhalidwe yophatikizira pansi pa matrices osiyanasiyana ndizovuta kwambiri. Komabe, pali mwayi wofufuza mozama za kukhathamiritsa kusakanikirana kosakanikirana ndi njira zomwe zimapangidwira.

2 Kusintha kwamphamvu

Pakadali pano, kusinthidwa kwa fiber interface kumagwiritsidwa ntchito makamaka kuthetsa vuto la fiber-material bonding in Mtengo wa BFRP. Ngakhale onse amatha kukwaniritsa cholinga chokulitsa malo enieni komanso mphamvu zomangirira pakati pa zolumikizira, njira iliyonse yosinthira ili ndi malire, monga kulephera kupanga zochuluka, kuwononga chilengedwe, komanso njira zovuta. Ngakhale mitundu yambiri yosinthira pawiri imatha kukwaniritsa cholinga chokwaniritsa zabwino za wina ndi mnzake, pakadali pano, palibe kusanthula mwadongosolo pamilandu yofananira, kusintha kosinthika, komanso kugwiritsa ntchito kwenikweni kwa BF kusinthidwa kwapawiri pansi pa masamu osiyanasiyana. Kuphatikizika kwa ulusi kumatha kukhala ndi zotsatira zabwino zosakanizidwa, koma pali zinthu zambiri zomwe zimakhudza kukulitsa kwa kuphatikizika kwa ulusi. Kutalika kosiyanasiyana ndi mitundu ya ulusi zimatha kukwaniritsa zolimbikitsa zosiyanasiyana, ndipo kuphatikizika kwakukulu kapena kocheperako kumakhudza kulimbikitsa, kulephera kukwaniritsa zomwe zikuyembekezeka, komanso kuchepetsa magwiridwe antchito azinthuzo. Ngakhale pali maphunziro okhudzana ndi kutalika koyenera kosakanikirana, mulingo, ndi kuchuluka kwa magwiridwe antchito a BF pansi pa masamu osiyanasiyana, kupita patsogolo kwa kafukufuku wokhudzana ndi kuphatikizika kotengera zinthu zosiyanasiyana ndi kosiyana, ndipo pali kusowa kwa kafukufuku mwatsatanetsatane komanso mwachidule pamitundu, utali, ma ratio, milingo ndi njira zosakanikirana za ulusi wosakanikirana.

3 Zovuta Zogwiritsa Ntchito

Kulimbitsa kamangidwe kanyumba, komanso misewu yamayendedwe ndi BFRP yomwe imagwiritsidwa ntchito kwambiri, njira yayikulu kwambiri. Ambiri mwachindunji kusanganikirana ndondomeko ndi konkire, nthaka, phula, gypsum, ndi zina gulu BFRP. Phindu lake lowonjezera ndilotsika, ndipo kafukufuku wamakono pazinthu zoterezi amayang'ana kwambiri mphamvu za zitsanzo za BFRP, Kukaniza kwa Corrosion, porosity, etc., komabe, pali zochepa zomwe zili pamwambazi muzogwiritsira ntchito zamakono zamakono m'malo ogwirira ntchito ziwerengero ndi kafukufuku.Mtengo wa BFRP popanga magalimoto opepuka komanso amphamvu kwambiri, zida zopepuka zowoneka bwino zamlengalenga, zida zapaipi zapaipi zamphamvu zolimba kwambiri, etc. ndizosakwanira pang'ono. Komabe, pali ziwerengero ndi maphunziro ochepa pakuchita kwa Mtengo wa BFRP m'mapulogalamu enieni a engineering. Mwachitsanzo, thermoplastic polima composite chitoliro mapeto ndi ukadaulo wolumikizira chitoliro akadali ndi vuto, potengera kulimbikira kwambiri, chitoliro chamafuta a BFRP ndi casing zili ndi malire.
