Pankhani yokongoletsa zomangamanga ndi kupanga mafakitale, ma coil a aluminiyamu okhala ndi mitundu yosiyanasiyana akukhala njira yabwino kwambiri m'malo mwa zipangizo zachikhalidwe chifukwa cha magwiridwe antchito abwino komanso mitundu yosiyanasiyana. Mtundu uwu wa coil, womwe umachokera ku aluminiyamu ndipo umapakidwa utoto ndi utoto pamwamba, umasunga ubwino wa aluminiyamu.—yopepuka komanso yosagwira dzimbiri—komanso kukhala ndi kukongola kolemera komanso magwiridwe antchito kudzera mu kukonza, zomwe zimapangitsa kuti igwiritsidwe ntchito kwambiri m'mafakitale osiyanasiyana.
Zipangizo zoyambira za ma coil a aluminiyamu okhala ndi mitundu yambiri ndi makamaka ma alloy a aluminiyamu amtundu umodzi, atatu, ndi asanu. Kusiyana kwa makhalidwe a mitundu yosiyanasiyana ya zipangizo zoyambira kumakhudza mwachindunji zochitika zomwe zikugwiritsidwa ntchito:
Aluminiyamu yoyera ya mndandanda umodzi (nthawi zambiri 1060): Njira yosavuta yopangira, mtengo wotsika, koma zinthuzo ndi zofewa, zoyenera zochitika zonse zomwe zimakhala ndi mphamvu zochepa (monga kutchinjiriza mapaipi, zikwangwani), zomwe zimapangitsa kuti zikhale zotsika mtengo kwambiri.
Ma aluminiyamu-manganese amitundu itatu (omwe nthawi zambiri amakhala 3003/3004): 3003 ili ndi manganese a 1.0-1.5%, omwe amapereka kukana dzimbiri. Kuuma kwake ndi mphamvu zake zokoka ndizopambana kuposa ma aluminiyamu amitundu imodzi, zomwe zimapangitsa kuti ikhale chinthu chogwiritsidwa ntchito kwambiri. 3004 ili ndi magnesium yowonjezera ya 0.8-1.3% (yomwe imadziwikanso kuti aluminum-magnesium-manganese alloy), zomwe zimapangitsa kuti ikhale yolimba kwambiri komanso yoyenera kumanga madenga okhala ndi mphamvu zambiri. Mtengo wake ndi wokwera pang'ono kuposa 3003.
Ma aluminiyamu ndi magnesiamu amitundu 5 (omwe nthawi zambiri amakhala 5052): Ali ndi magnesium ya 3-5%, ma alloys awa ali ndi mphamvu zochepa, mphamvu zambiri zokoka, komanso ndi opepuka. Ndi okwera mtengo kwambiri ndipo nthawi zina amagwiritsidwa ntchito popanga ma coil a aluminiyamu okhala ndi utoto wapamwamba, omwe poyamba amagwiritsidwa ntchito kwambiri m'munda wa ndege.
Kupaka utoto ndiye "moyo wofunikira" wa ma coil a aluminiyamu okhala ndi utoto. Kapangidwe ndi njira zosiyanasiyana zopaka utoto zimatsimikiza momwe mtundu wa chinthucho umakhudzira, kukana kwa nyengo, komanso magwiridwe antchito. Pakadali pano, njira yayikulu yopaka utoto ndi "zophimba ziwiri ndi zophika ziwiri," ndipo zinthu zina zapamwamba zimagwiritsa ntchito "zophimba zitatu ndi zophika zitatu." Kapangidwe kake kali ndi zigawo zitatu kuchokera mkati kupita kunja: Chisanu chokonzekera: "Chotchinga choteteza pansi." Filimu yokhuthala ya oxide, pafupifupi 5-10 nm, imapangidwa pamwamba pa aluminiyamu kudzera mu chromating kapena passivation yopanda chromium. Izi zimawonjezera kumamatirana pakati pa substrate ndi zopaka utoto, zimaletsa kupukuta kwa utoto, komanso zimathandizira kukana dzimbiri, ndikuyika maziko a zopaka zotsatira.
Gawo Loyambira: “Cholumikizira Chapakati ndi Gawo Loteteza.” Epoxy kapena polyester resin imagwiritsidwa ntchito ngati gawo loyambira, pafupifupi 5-10μmakulidwe a m. Ntchito yake yayikulu ndikuwonjezera kukanikiza ndikuletsa chinyezi chakunja ndi mpweya kuti zisakhudze gawo lapansi, zomwe zimapangitsa kuti dzimbiri lisagwe. Mtundu wa primer ukhoza kusinthidwa malinga ndi zofunikira za topcoat kuti zitsimikizire kuti mtundu womaliza umakhala wofanana komanso wowala.
Chovala cha Topcoat: “Chokongola ndi Chogwira Ntchito Kwambiri.” Mitundu yosiyanasiyana ya topcoat imasankhidwa malinga ndi zofunikira pakugwiritsa ntchito, pafupifupi 15-25μmakulidwe a m. Mitundu yodziwika bwino ya topcoat ndi iyi: Utoto wa Fluorocarbon (PVDF): “Mfumu Yolimba Panja.” Yopangidwa ndi polyvinylidene fluoride resin, ili ndi mphamvu zabwino kwambiri zotsutsana ndi UV komanso zoletsa ukalamba. Pa kutentha kwa -40℃mpaka 150℃, utoto wake umatha kutha ndipo chophimbacho sichimasweka mosavuta. Chilinso ndi mphamvu zodziyeretsera zokha; madzi amvula amatha kuchotsa fumbi la pamwamba mosavuta, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito kwa nthawi yayitali monga makoma akunja ndi makatani akunja. Nthawi yogwiritsira ntchito chophimbacho imatha kufika zaka zoposa 20.
Utoto wa polyester (PE): “Chisankho chotsika mtengo.” Mtengo wake ndi wotsika ndi 40%-50% kuposa utoto wa fluorocarbon. Ngakhale kuti utoto wake woletsa kukalamba si wabwino ngati utoto wa fluorocarbon, ukhoza kutsimikizirabe kuti ungagwiritsidwe ntchito kwa zaka 10-15 m'madera omwe si otentha kwambiri (monga Central ndi Southern China). Ulinso ndi mitundu yosiyanasiyana, kuphatikizapo utoto wowala kwambiri, wowala kwambiri, komanso wachitsulo, woyenera kugwiritsidwa ntchito kunja kwa fakitale, m'mabokosi a zida, komanso m'madenga amkati.
Utoto wa polyester wosinthidwa ndi silicone (SMP): "Njira yabwino yogwirira ntchito." Kuphatikiza kutsika mtengo kwa utoto wa polyester ndi kukana kwa nyengo kwa utoto wa fluorocarbon, umapereka kukana kwa UV kwambiri poyerekeza ndi utoto wamba wa polyester, umakhala ndi moyo wa zaka 12-18, ndipo ndi wotsika mtengo kuposa utoto wa fluorocarbon. Izi zimapangitsa kuti ukhale woyenera mapulojekiti omwe ali ndi zofunikira zina zotsutsana ndi nyengo koma bajeti yochepa, monga madenga a nyumba zamalonda ndi madenga a malo osungira mafuta.
Ndi kupita patsogolo kosalekeza muukadaulo wazinthu, ma coil a aluminiyamu okhala ndi utoto adzakula kukhala abwino kwambiri kwa chilengedwe, magwiridwe antchito ambiri, komanso kusintha mawonekedwe a munthu. Kumbali imodzi, ma coil a aluminiyamu okhala ndi utoto woteteza chilengedwe (monga ma coil opanda chromium ndi utoto wochokera m'madzi) pang'onopang'ono adzalowa m'malo mwa ma coil achikhalidwe, kuchepetsa kuwonongeka kwa chilengedwe. Kumbali ina, ma coil a aluminiyamu okhala ndi utoto wokhala ndi ntchito zapadera, monga ma coil oletsa mabakiteriya, oletsa moto, komanso odzichiritsa okha, adzapitiriza kuonekera, kukwaniritsa zosowa za zochitika zapadera. Nthawi yomweyo, ntchito zosinthira zomwe munthu akufuna zidzakhala zambiri, zomwe zimalola mitundu ndi mawonekedwe osinthidwa kutengera zomwe ogwiritsa ntchito akufuna, ndikukulitsa kuchuluka kwa ma coil a aluminiyamu okhala ndi utoto.
