Muminda yekushongedza zvivakwa uye kugadzira maindasitiri, macoil ealuminium ane mavara ari kuve imwe nzira inofarirwa pane zvinhu zvechinyakare nekuda kwekushanda kwawo kwakanaka uye mhando dzakasiyana. Rudzi urwu rwecoil, rwakavakirwa paaluminium alloy uye rwakagadziriswa nependi yepamusoro uye pendi, runoramba ruine zvakanakira zvearuminiyamu.—yakareruka uye inodzivirira ngura—ukuwo ichipiwa runako rwakapfuma uye mashandiro kuburikidza nekugadzirisa, zvichiita kuti ishandiswe zvakanyanya mumaindasitiri akasiyana-siyana.
Zvinhu zvekutanga zvemakoiri ealuminium ane mavara zvinonyanya kuve 1-series, 3-series, uye 5-series alloys ealuminium. Kusiyana kwehunhu hwezvinhu zvakasiyana-siyana zvebase kunokanganisa zvakananga mamiriro ezvinhu anoshanda:
Aruminiyamu yakachena ine 1-series (inowanzo 1060): Maitiro ekugadzira ari nyore, mutengo wakaderera, asi chinhu chacho chakapfava, chakakodzera mamiriro ezvinhu akajairika ane simba shoma (senge kuputira mapaipi, mabhodhibhodhi), zvichipa kushanda kwepamusoro-soro.
Ma alloy e aluminium-manganese ane 3-series (anowanzo 3003/3004): 3003 ine 1.0-1.5% manganese, ichipa kudzivirira ngura kwakanaka. Kuoma kwayo uye simba rayo rekudhonza zvakapfuura ma alloy e 1-series, zvichiita kuti ive chinhu chinonyanya kushandiswa. 3004 ine imwe 0.8-1.3% magnesium (inozivikanwawo se aluminium-magnesium-manganese alloy), zvichikonzera simba rakawanda uye kukodzera kuvaka matenga ane zvinodiwa zvakasimba zvekuvaka. Mutengo wayo wakakwira zvishoma pane 3003.
Ma alloy e aluminium-magnesium ane 5-series (anowanzo shandiswa 5052): Ane 3-5% magnesium, aya ma alloy ane density shoma, simba guru rekudhonza, uye akareruka. Anodhura zvakanyanya uye dzimwe nguva anoshandiswa mukugadzira ma coil e aluminium ane mavara emhando yepamusoro, pakutanga ainyanya kushandiswa mumunda wendege.
Kuputira ndiyo "pfungwa huru" yearuminiyamu coils dzakaputirwa nemavara. Magadzirirwo akasiyana ekuputira uye maitiro anoona mhedzisiro yeruvara rwechigadzirwa, kuramba kwemamiriro ekunze, uye mashandiro azvo. Parizvino, maitiro makuru ekuputira i "kuputira kaviri uye kubheka kaviri," nezvimwe zvigadzirwa zvepamusoro zvinoshandisa "kuputira katatu uye kubheka katatu." Chimiro chaicho chine zvikamu zvitatu kubva mukati zvichienda kunze: Chimiro chepamberi pekurapa: "Chinodzivirira pasi." Firimu re dense oxide, rine ukobvu hwe5-10 nm, rinoumbwa pamusoro pearuminiyamu substrate kuburikidza ne chromating kana chromium-free passivation. Izvi zvinowedzera kunamira pakati pe substrate ne coatings, zvinodzivirira kuputira, uye zvinovandudza kuramba kwengura, zvichiisa hwaro hwe coatings dzinotevera.
Chikamu Chekutanga: "Chinobatanidza Pakati nePakati uye Chikamu Chinodzivirira." Epoxy kana polyester resin inoshandiswa sechikamu chekutanga, inenge 5-10μukobvu hwem. Basa rayo guru nderekuwedzera kunamira uye kudzivirira hunyoro hwekunze neokisijeni kuti zvisabate substrate, zvichivandudza kuramba kwengura. Ruvara rweprimer runogona kugadziriswa zvichienderana nezvinodiwa netopcoat kuti ive nechokwadi chekuti ruvara rwekupedzisira rwakafanana uye runopenya.
Rutivi rweTopcoat: “Rutivi rweCore Runoyevedza uye Runoshanda.” Mhando dzakasiyana dzetopcoats dzinosarudzwa zvichienderana nezvinodiwa pakushandisa, dzinenge 15-25μukobvu hwem. Mhando dzema topcoat anowanzo sanganisira: Pendi yeFluorocarbon (PVDF): “Mambo weKugara Kwekunze.” Yakagadzirwa ne polyvinylidene fluoride resin, ine simba rakanaka rekudzivirira UV uye kudzivirira kukwegura. Mukati mekupisa kwe -40℃kusvika 150℃, ruvara rwacho haruperi kupera simba uye pendi yacho haipenyeki. Ine hunhu hwakasimba hwekuzvichenesa; mvura inonaya inogona kubvisa guruva repamusoro zviri nyore, zvichiita kuti ive yakakodzera kushandiswa kwenguva refu senge pakuvaka kunze nemadziro emaketeni ekunze. Nguva yekupfeka inogona kusvika makore anopfuura makumi maviri.
Pendi yepolyester (PE): "Sarudzo inodhura zvishoma." Mutengo wayo wakaderera ne40%-50% pane pendi yefluorocarbon. Kunyange zvazvo kushanda kwayo kwekudzivirira kukwegura kusina kunaka sependi yefluorocarbon, inogona kuramba ichivimbisa hupenyu hwemakore gumi kusvika gumi nemashanu munzvimbo dzisina mamiriro ekunze akanyanya (senge Central neSouthern China). Inopawo mavara akasiyana-siyana, anosanganisira matte yakagadzirwa, high-gloss, uye simbi, yakakodzera kunze kwefekitori, macasing emidziyo, uye denga remukati.
Pendi yepolyester yakagadziriswa nesilicone (SMP): "Sarudzo yekushanda zvakanaka." Kubatanidza kushanda zvakanaka kwependi yepolyester nekusashanda zvakanaka kwependi yefluorocarbon, inopa simba rekudzivirira UV kupfuura pendi yepolyester yakajairika, ine hupenyu hwemakore 12-18, uye inodhura zvishoma pane pendi yefluorocarbon. Izvi zvinoita kuti ive yakakodzera kumapurojekiti ane zvinodiwa zvekudzivirira mamiriro ekunze asi bhajeti shoma, senge mahwindo enzvimbo dzekutengesa uye macanopies enzvimbo dzepeturu.
Nekufambira mberi kuri kuitwa muhunyanzvi hwezvinhu, macoil ealuminium ane mavara achakura kuti ave nehushamwari kune nharaunda, kushanda kwakawanda, uye kugadzirwa kwakawanda. Kune rumwe rutivi, macoil ane hushamwari kune nharaunda (akadai semacoil asina chromium uye pendi dzinobva mumvura) achatsiva zvishoma nezvishoma macoil echinyakare, zvichideredza kukanganisa nharaunda. Kune rumwe rutivi, macoil ealuminium ane mavara ane mabasa akakosha, akadai semacoil anorwisa mabhakitiriya, anodzivirira moto, uye anozviporesa, acharamba achibuda, achizadzisa zvinodiwa nemamiriro ezvinhu akanyanya. Panguva imwe chete, masevhisi ekugadzirisa akasarudzika achava akazara, achibvumira mavara akagadziridzwa uye magadzirirwo zvichienderana nezvinodiwa nemushandisi, zvichiwedzera kuwedzera kwekushandiswa kwemacoil ealuminium ane mavara.
