Kunamagama ahlukene kuye ngokuthi hlobo luni lopende olusetshenzisiwe, isibonelo, i-primer coat ibizwa ngokuthi i-primer coat, futhi ijazi lokuqeda libizwa ngokuthi i- finish coat .Ngokuvamile, ukunamathela okutholwe ngokumboza kuncane kakhulu, cishe ama-microns angu-20 ~ 50, futhi ukunamathela okunamathiselwe okuminyene kungathola ukunamathela okunogqinsi olungaphezu kuka-1 mm ngesikhathi.
Kuwungqimba oluncane lwepulasitiki olumbozwe ngensimbi, indwangu, ipulasitiki nezinye izinto ezingaphansi ukuze zivikeleke, zifakwe ngaphakathi, zihlobise nezinye izinjongo.
Ukushisa okuphezulu kokushisa kagesi kwe-insulation coating
I-conductor eyenziwe ngethusi, i-aluminium nezinye izinsimbi imbozwe ngopende wokuvikela noma ipulasitiki, irabha nezinye izigqoko zokuvikela.Kodwa-ke, upende wokufaka insulating, ipulasitiki kanye nerabha besaba ukushisa okuphezulu.Ngokuvamile, uma izinga lokushisa lingaphezu kuka-200 ℃, zizoqoqana futhi zilahlekelwe izakhiwo zazo zokuvikela.Futhi izintambo eziningi zidinga ukusebenza ngaphansi kwezinga lokushisa eliphezulu, yini okufanele siyenze?Yebo, vumela i-coating kagesi esezingeni eliphezulu isize.Lokhu kunamathela empeleni kuyi-ceramic coating.Ngaphezu kokugcina ukusebenza kokufakwa kukagesi emazingeni okushisa aphezulu, kungase futhi "kuhlanganiswe" eduze nocingo lwensimbi ukuze kuzuzwe "okungenasici".Ungakwazi ukugoqa ucingo izikhathi eziyisikhombisa nesishiyagalombili, futhi ngeke bahlukane.Lokhu kunamathela kuminyene kakhulu.Uma uyisebenzisa, izintambo ezimbili ezinomehluko omkhulu kagesi zizoshayisana ngaphandle kokuphuka.
Izembatho zokushisa eziphakeme zokushisa kagesi zingahlukaniswa zibe izinhlobo eziningi ngokusho kokwakheka kwazo kwamakhemikhali.Isibonelo, i-boron nitride noma i-aluminium oxide noma i-copper fluoride enamathela endaweni ye-graphite conductor isenokusebenza okuhle kokufakwa kukagesi ku-400 ℃.Uqweqwe olusocingweni lwensimbi lufinyelela ku-700 ℃, i-phosphate based binder coating ifinyelela ku-1000 ℃, futhi i-plasma sprayed aluminium oxide coating ifinyelela ku-1300 ℃, konke okusagcina ukusebenza kahle kokufakwa kukagesi.
Izindwangu zokushisa eziphakeme zokushisa zikagesi zisetshenziswe kabanzi emandleni kagesi, izinjini, izinto zikagesi, i-electronics, izindiza, amandla e-athomu, ubuchwepheshe besikhala, njll.

Ngokusho kwesigaba se-FNLONGO sezingubo zokufafaza ezishisayo, ukunamathela kungahlukaniswa kube:
1. Gqoka ukunamathela okuqinile
Ihlanganisa ukumelana nokunamathela okunamathelayo, ukumelana nokukhathala okungaphezulu kanye nezingubo ezimelana nokuguguleka.Kwezinye izimo, kunezinhlobo ezimbili zama-coatings amelana nokugqokwa: izinga lokushisa eliphansi (<538 ℃) lifaka ama-coatings amelana nezinga lokushisa eliphezulu (538~843 ℃) gqoka ama-coatings amelana.
2. Inamathela ekushiseni futhi imelana ne-oxidation
I-coating ifaka phakathi izintambo ezisetshenziswa ezinqubweni zokushisa okuphezulu (okuhlanganisa umoya we-oxidation, igesi egqwalayo, ukuguguleka komhlabathi kanye nesithiyo esishisayo esingaphezu kuka-843 ℃) kanye nezinqubo zensimbi encibilikisiwe (okuhlanganisa i-zinc encibilikisiwe, i-aluminium encibilikisiwe, insimbi encibilikisiwe nensimbi, nethusi elincibilikisiwe).
3. Anti atmospheric kanye nokucwiliswa ukugqwala ezinengilazi
Ukugqwala kwe-atmospheric kubandakanya ukugqwala okubangelwa umkhathi wezimboni, umkhathi kasawoti kanye nomkhathi wasendle;Ukugqwala kokucwiliswa kuhlanganisa ukugqwala okubangelwa ukuphuza amanzi ahlanzekile, ukungaphuzi amanzi ahlanzekile, amanzi ashisayo ashisayo, amanzi anosawoti, amakhemikhali kanye nokucubungula ukudla.
4. Conductivity kanye ukumelana enamathela
Lesi sitshalo sisetshenziselwa ukuvikela, ukuguquguquka, nokuqina.
5. Buyisela i-dimensional coating
Lokhu kunamathela kusetshenziselwa insimbi esekelwe (insimbi eshintshwayo negaywayo yekhabhoni nensimbi engagqwali) kanye nensimbi engeyona ayoni (i-nickel, i-cobalt, ithusi, i-aluminium, i-titanium nama-alloys ayo).
6. I-Gap control coating yezingxenye zemishini
Lokhu kunamathela kuyagaya.
7. I-Chemical resistant coating
Ukugqwala kwamakhemikhali kuhlanganisa ukugqwala kwama-asidi ahlukahlukene, ama-alkali, usawoti, izinto ezihlukahlukene ezingaphili kanye nemidiya ehlukahlukene yamakhemikhali ephilayo.
Phakathi kwemisebenzi yokumboza engenhla, ukunamathela okungagqoki, ukumelana nokushisa kanye ne-oxidation ukumelana ne-oxidation kanye ne-chemical corrosion resistant coating kuhlobene eduze nokukhiqizwa kwemboni ye-metallurgical.

Ngokwesibonelo, yethuImikhiqizo ye-PC kanye ne-PMMAngokuvamile sebenzisa enamathela.
Imikhiqizo eminingi ye-PC kanye ne-PMMA inezidingo eziphezulu ezingaphezulu, okuyizidingo ezijwayelekile zokubona.Ngakho-ke, ingaphezulu lomkhiqizo kufanele liboshwe ukuvimbela ukunwaya.
