Munthu wosadziŵika sangathe kulingalira kuti ndi zingati zingapo zomwe zimakhala zosavuta kumayambiriro koyang'ana, monga kusankha msasa . Kotero, mwachitsanzo, palibe makope oposa chikwi amathyoledwa pamakangano a pa Intaneti pa nkhani yabwino yokonzekera mahema a hema. Kodi nsalu ya hema ili bwino - aluminiyumu kapena fiberglass - tiyeni timvetse pamodzi.
Magome a ma tebulo a glass
Ubwino wa glass fiberglass, komanso mitundu ina ya pulasitiki, ngati zipangizo zopangira mahema, akhala akuyamikiridwa ndi pafupifupi onse opanga zida. Choncho, dziwitseni nokha - telo ya fiberglass imapindulitsa kwambiri aluminiyumu mumtengo, omwe sangathe koma okondwa alendo oyendayenda. Pamodzi ndi izi, magetsi a glass fiberglass amayesetsa mokwanira pa ntchito yomwe akuyang'anila - amasonkhanitsidwa mosavuta ndi osokonezeka ndi opunduka pang'ono panthawiyi. Panthawi imodzimodziyo, ali ndi zotsatira zochepa - poyambira kutentha, fiberglass imakhala yofooka ndipo pang'onopang'ono imayamba kusweka. Musamamukonda iye komanso kuyanjana kwa nthawi yaitali ndi madzi. Chifukwa chake, arcs ya glass fiberglass adzakhala njira yabwino kwa alendo oyendayenda, omwe sakhala nawo maulendo aifupi. Odziwa alendo, omwe amazoloŵera maulendo ataliatali komanso omwe ali ndi magalasi onse ofunika kwambiri, m'pofunikira kusankha masentimita a mahema a aluminum alloys.
Aluminium arcs kwa mahema
Mosiyana ndi anzawo apulasitiki, aluminium arcs alibe zolakwika zambiri. Choncho, ali ndi zolemetsa zochepa kwambiri, zomwe ndizofunika kwambiri popita kumalo ovuta. Chachiwiri, arcs kuchokera ku aluminium saopa zinthu zoopsa: kulekerera mwamphamvu kutentha kwakukulu kusintha, kutentha kwambiri ndi kutuluka kwa ultraviolet. Kuipa kwawo kwakukulu kungatchedwe kokha ndalama zokwanira, zomwe zimapangitsa kuti zikhale zomveka kuti zikhale nazo pokhapokha ngati zikugwiritsidwa ntchito mwakhama. Koma vuto ili ndilo mbali yina ya ulemu wawo: kupanga mahema pamodzi
Zomwe mungapangitse arcs kuhema?
Chikhalidwe pamene chihema chimasinthika chifukwa cha ziphuphu zosweka nthawi zambiri zimakumana. Njira yophweka ndiyo kuchoka magulu a arcs mu sitolo yapadera. Koma ngati izi sizingatheke pazifukwa zilizonse, ndizomveka kupanga arcs kuchokera kumapope a aluminium, kuwadula mu zigawo ndi kutalika kwa masentimita 80. Mapeto a zigawozo ayenera kusinthidwa m'njira yomwe amatha kukondana.
