Mapepala a Al-Mg-Mn Amamanga Ma Denga Amakono Olimba, Opepuka

Ma plate a Al-Mg-Mn amathandizira mapulojekiti ambiri amakono omanga. Kulemera kwawo kopepuka kumathandiza opanga mapulani kuchepetsa katundu womangidwa ndi pafupifupi 35%. Malo awo olimba a pamwamba amathandizanso madera amphamvu amphepo omwe amafika 60 m/s. Omanga ambiri tsopano amagwiritsa ntchito ma plate awa m'mabwalo a ndege, m'masiteshoni, ndi m'mabwalo amasewera. Chopangirachi chikuwonetsa magwiridwe antchito okhazikika m'nyengo yozizira komanso yotentha. Magulu ambiri amasankha izi chifukwa zimakhala zolimba kwa zaka zoposa 25.

Anthu Otchulidwa

Ma plate a Al-Mg-Mn amachokera ku alloy yokhala ndi zitsulo zitatu zofunika. Aluminiyamu imapanga pafupifupi 95% ya kusakaniza komaliza. Magnesium imakhala ndi pafupifupi 3%. Manganese imakhala ndi pafupifupi 1%. Chiŵerengero chosavuta ichi chimapangitsa alloy kukhala yolimba popanda kulemera kwakukulu. Mapanelo ambiri amafika pa mphamvu yokoka pafupifupi 210 MPa. Zipangizozo zimakhalabe zogwira ntchito ngakhale kutentha kukatsika kufika pa −40 °C. Ogwira ntchito amatha kupindika ma plate pa radius ya 20 mm popanda ming'alu.

Pamwamba pake pamasonyeza khalidwe lamphamvu loletsa dzimbiri. Mayeso opopera mchere amatha kugwira ntchito kwa maola 3000 popanda kusintha kwakukulu. Chitsulocho chimapanga filimu yokhuthala ya okosijeni pasanathe mphindi 30 mutachigwiritsa ntchito. Filimuyi imaletsa kuukira kwa mankhwala ambiri. Ma plates amasunganso mtundu wokhazikika pamene chizindikiro cha UV chikufika pa 11 kapena kuposerapo. Madenga ambiri a stadium amafunika kukhazikika kumeneku chifukwa madenga akuluakulu amakumana ndi kuwala kwa dzuwa kwa maola ambiri.

Mapepalawa amasonyeza mphamvu yabwino kwambiri yopangira zinthu. Magulu opanga zinthu amatha kukulunga mapepalawo m'makhonde aatali omwe amafika mamita 60 m'litali. Mapanelo aatali amachepetsa kuchuluka kwa malo olumikizirana ndi pafupifupi 45%. Mapale ochepa amachepetsa chiopsezo cha kutayikira kwa madzi nthawi yamvula yambiri. Nyumba zazikulu za anthu onse zimafunikira phindu ili mvula ikafika mamita 200 pa ola limodzi.

Makhalidwe a alloy iyi amathandizira mapangidwe osiyanasiyana. Magulu amatha kupanga mapanelo owongoka kapena mawonekedwe opindika. Opanga ambiri amakonda malo osalala chifukwa amapereka kalembedwe kamakono. Ma plates amasunga malo oyera chifukwa oxide wosanjikiza umaletsa kumatirira fumbi. Ntchito yokonza imatsika ndi pafupifupi 30% chaka chilichonse. Makhalidwe awa amathandiza amalonda ambiri kuwongolera mtengo wa nthawi yayitali.

Ubwino

Ubwino woyamba umachokera ku kulemera kopepuka. Mbale yokhazikika imalemera makilogalamu 2.8 okha pa mita imodzi iliyonse. Mbale zachitsulo zimatha kufika makilogalamu 7.8 pa malo omwewo. Kusiyana kumeneku kumachepetsa katundu wa denga ndi pafupifupi 65%. Zipangizo zambiri zachitsulo zimatha kugwiritsa ntchito zigawo zazing'ono chifukwa cha khungu la denga lopepuka ili. Omanga nthawi zambiri amasunga 10% ya kuchuluka kwa chitsulo m'maholo akuluakulu.

Ubwino wachiwiri umachokera ku magwiridwe antchito a moyo wonse. Al-Mg-Mn yakhala ikugwiritsidwa ntchito bwino kwa zaka zoposa 30 m'madera a m'mphepete mwa nyanja. Mayeso akuwonetsa kutayika kwa malo osakwana 5% pambuyo poika mchere nthawi yayitali. Mabwalo ambiri a ndege m'mphepete mwa nyanja amafunikira kupirira kumeneku chifukwa mpweya nthawi zambiri umakhala ndi mchere wa 3%. Ma plates amasunganso mphamvu yokhazikika pakasintha kutentha pakati pa −40 °C ndi 80 °C.

Ubwino wachitatu umabwera chifukwa chosavuta kuyika. Ogwira ntchito amatha kukonza mapanelo akuluakulu pa liwiro la 15 m pa ola limodzi. Magulu ambiri omanga denga amagwiritsa ntchito makina omangira omwe amathamanga pa liwiro la 20 m pa mphindi imodzi. Dongosololi limalola zomangira zobisika zomwe zimateteza denga ku kutuluka kwa madzi. Mvula yamphamvu ya 150 mm pa ola limodzi nthawi zambiri imabweretsa mavuto. Cholumikizira chomangiracho chimalimbana ndi kupopera mphepo mpaka 3.0 kPa. Malo ambiri akuluakulu amafunika mtengo uwu chifukwa kutalika kwa malowa kumakhala ndi mphamvu zazikulu zokwezera.

Ubwino wachinayi umachokera ku mphamvu yoyera. Chitsulochi chimawonetsa pafupifupi 75% ya kuwala kwa dzuwa. Nyumba zambiri zosungiramo zinthu zimachepetsa kutentha kwa denga ndi 20%. Mphamvu ya mpweya woziziritsa ikhoza kutsika ndi 12% nthawi iliyonse yachilimwe. Opanga mapulani ambiri amagwiritsa ntchito ma plate awa padenga la solar panel chifukwa nyumbayo imafuna malo owala.

Makhalidwe ndi Mfundo Zogwiritsira Ntchito

Ma plate a Al-Mg-Mn amapereka phindu lalikulu m'malo ovuta. Nyumba zambiri za m'mapiri zimagwiritsa ntchito izi chifukwa zimasamalira chipale chofewa champhamvu. Ma plate amatha kunyamula chipale chofewa cholemera pafupifupi 2.0 kN pa mita imodzi ya sikweya ngati ataphatikizidwa ndi ma purlin amphamvu. Malo ambiri ochitira masewera otsetsereka pa ski amagwiritsa ntchito njira imeneyi chifukwa chipale chofewa cha m'nyengo yozizira chimatha kuwunjikana mamita oposa 1.2.

Ma plates amathandizanso kapangidwe ka madzi oyenda bwino. Ma board okhota amathandiza kutsogolera madzi nthawi yamkuntho. Madenga ambiri amagwiritsa ntchito malo otsetsereka pafupifupi 3%. Malo otsetserekawa amalola madzi kuyenda mofulumira ngakhale mvula ikafika 180 mm pa ola limodzi. Cholumikizira chobisika chimatsogolera dontho lililonse kupita ku ngalande. Kapangidwe kameneka kamapewa misampha yamadzi yomwe imayambitsa dzimbiri.

Chitsulochi chimathandizanso kuti moto ukhale wabwino. Ma plates amasungunuka pafupifupi 630 °C, koma sayatsa moto. Nyumba zambiri zimafuna khalidweli chifukwa malamulo a moto amachepetsa malo oyaka. Ma plates amalimbananso ndi kuwonongeka kwa nthunzi chifukwa cha kuwotcherera panthawi yokonza. Mayeso amasonyeza kupsa kwa pamwamba kosakwana 1 mm chifukwa cha nthunzi zamoto.

Mizere yopangira imatha kupereka ma plate ambiri. Mzere umodzi ukhoza kutulutsa 5000 m² patsiku. Makampani ambiri, monga Harbin Dongan Building Sheets Co., Ltd amagwiritsa ntchito makina odzigudubuza okha okhala ndi ma check 15 abwino. Zolakwika za miyeso zimakhala mkati mwa 0.2 mm. Miyeso yokhazikika imathandiza ogwira ntchito kumaliza denga mwachangu. Mapulojekiti ambiri akuluakulu amatha kukhazikitsa mkati mwa masiku 20 pamene malowo amafika 40,000 m².

Chitsulochi chimasonyezanso kufunika kobwezeretsanso zinthu mwamphamvu. Zinthu zobwezerezedwanso zimasunga zoposa 90% ya ntchito yake yoyambirira. Mapulojekiti ambiri obiriwira amasankha chitsulochi chifukwa chimathandizira zolinga zotsika mpweya. Kubwezeretsanso zinthu kungachepetse kugwiritsa ntchito mphamvu ndi 60%. Mitengo iyi ikuwonetsa ubwino waukulu kwa nthawi yayitali.

Mbale ya Al-Mg-Mnzimapatsa nyumba zamakono mphamvu, zopepuka, komanso zolimbamakina a denga. Kusakaniza kwawo kokhazikika kwa aloyi kumapereka magwiridwe antchito odalirika m'nyengo zovuta. Mapulojekiti ambiri amadalira chipangizochi kuti chikhale ndi nthawi yayitali komanso ntchito yayitali. Ma plates amathandizanso opanga zinthu kuchepetsa katundu, kusunga mphamvu, komanso kuchepetsa ndalama zokonzera. Kutha kupanga kwawo kumathandizira mawonekedwe opindika komanso owongoka. Kukana kwawo dzimbiri kumagwirizana ndi madera a m'mphepete mwa nyanja, mafakitale, ndi madera okwera. Mitengo yophatikizidwayi ikufotokoza kufunikira komwe kukukulirakulira m'mabwalo a ndege, masiteshoni, ndi maholo akuluakulu. Chipangizochi chimapereka moyo wautali komanso kuwongolera mtengo kokhazikika.
