Pokonzanso, anthu ena amasankha mawaya amitundu yosiyanasiyana malinga ndi momwe amagwiritsira ntchito mphamvu.Komabe, kukonzanso kutatha, kudzaza dera ndi mavuto ena nthawi zambiri zimachitika.Ndiye vuto lili kuti?Chifukwa chachikulu ndi chakuti amagwiritsa ntchito waya wa aluminiyamu kapena waya wovala mkuwa.Kodi pali kusiyana kotani pakati pa waya wamkuwa ndi waya wa aluminiyamu, ndipo kuipa kogwiritsa ntchito waya wa aluminiyamu ndi kotani?Lero ndikuuzeni za izo.
Waya wa aluminiyamu wokongoletsa nyumba anali wamba m'madera akumidzi.Komabe, ndi chitukuko cha nthawi, kutchuka kwa zipangizo zosiyanasiyana zapakhomo kwakhala kokulirapo m'madera akumidzi.Waya wa aluminiyamu wokongoletsa nyumba sungathe kupirira magetsi ochulukirapo ndipo adachotsedwa kalekale.Mizinda ikuluikulu yomwe imagwiritsa ntchito magetsi kwambiri ndiyosavuta kuganizira mawaya a aluminiyamu.
Nanga n’cifukwa ciani tifunika kugwilitsila nchito waya wa mkuwa pokongoletsa m’malo mwa waya wotchipa wa aluminiyamu?
Chifukwa 1: Kutsika konyamula katundu
Monga tafotokozera pamwambapa, chimodzi mwazifukwa zomwe mawaya a aluminiyamu adachotsedwa ndi kutsika konyamulira: muyezo wosankha mawaya ndi mphamvu yonyamulira waya - kudzera mu mphamvu yonyamulira, titha kuwerengera kuchuluka kwa waya kumafunika kunyamula. zambiri zamakono.
Kutha kwa waya wa aluminiyamu ndi 1/3 ~ 2/3 ya waya wamkuwa.Mwachitsanzo, kwa waya wa 4 square, ngati ndi mkuwa, mphamvu yonyamulira ndi pafupifupi 32A;ngati ndi aluminiyamu pachimake, mphamvu yonyamula ndi pafupifupi 20A.
Choncho, tikamanena kuti dera linalake limafuna mawaya 4 masikweya mita, tikutanthauza kuti zonse ndizitsulo zamkuwa, zomwe zimatha kunyamula 32A yamakono.Panthawiyi, sikokwanira kuyika 4 lalikulu mamita a aluminiyamu waya ndi kunyamula mphamvu 20A yekha.Kuonjezera apo, ngati mukuyenera kugwiritsa ntchito mawaya akuluakulu a aluminiyamu m'malo mwa mawaya amkuwa, machubu a waya omwe amafunikira kuti azitha kupangira ulusi nawonso adzakhala okulirapo ndipo malo ofunikira adzakhala aakulu, kotero kuti mtengo woyakira sudzakhala wotsika kusiyana ndi kugwiritsa ntchito mawaya amkuwa.zambiri za.
Chifukwa 2: Malumikizidwe a Copper-aluminium amawonongeka mosavuta
Malingana ngati pali mawaya a aluminiyamu m'nyumba, mosakayikira padzakhala malo omwe mkuwa ndi aluminiyumu zimagwirizanitsidwa.Mkuwa ndi aluminiyamu zimagwirizana mwachindunji.Mphamvu yamagetsi ikagwiritsidwa ntchito, zomwe zimachitika ngati batri yoyamba zidzachitika: aluminiyumu yogwira ntchito kwambiri imafulumizitsa okosijeni, kupangitsa kuti mafupa azikhala otsika mpaka kuchulukira kukuchitika, chomwe ndi chimodzi mwazifukwa zomwe zimachitika nthawi zambiri ngozi zikachitika. pogwiritsa ntchito mawaya a aluminiyamu.
Chifukwa chokha chomwe anthu ambiri amagwiritsabe ntchito mawaya a aluminiyamu ndi chifukwa chotsika mtengo.Komabe, kuwonjezereka kwa ndalama zomangira poyala mawaya a aluminiyamu kapena ndalama zokonzetsera pambuyo pake komanso kugwiritsa ntchito mphamvu zambiri kumakhala kosavuta kuwona poyerekeza ndi mawaya amkuwa.Kupindula kumaposa kutayika, osatchulapo za chitetezo ndi zoopsa zobisika zomwe zimachitika pogwiritsa ntchito waya wa aluminiyamu.
