Dacromet Coated Flange Bolts- Tataiso e Felletseng ea Tekheniki mabapi le Moralo, Theknoloji ea ho Koahela, le Likopo tsa Liindasteri.
2026-08-12
1. Selelekela
Li-flange bolts li emela sehlopha sa bohlokoa sa li-fasteners tsa indasteri, tse kopanyang ts'ebetso ea bolt e tloaelehileng le flange e kopantsoeng e kang oasher tlas'a hlooho ea bolt. Ha li kopantsoe le theknoloji ea ho roala ea Dacromet, li-fasteners tsena li finyella tekanyo e ikhethang ea matla a mochine le ho hanyetsa kutu, ho etsa hore e be tsa bohlokoa haholo libakeng tse boima tse kang ho etsa likoloi, kaho, boenjiniere ba metsing le mechine e boima.
Sengoliloeng sena se fana ka tlhahlobo e qaqileng ea liboutu tsa Dacromet tse koahetsoeng ka li-flange ho tsoa liponong tse peli tse tlatselletsang: moralo oa sebopeho le thepa ea mochini ea li-flange bolts, le theknoloji e tsoetseng pele ea kalafo ea holim'a metsi e tsejoang e le Dacromet. Ka kopanelo, lintlha tsena li hlalosa tharollo e potlakileng e fihlelang litlhoko tse thata tsa lits'ebetso tsa sejoale-joale tsa boenjiniere.
2. Ho utloisisa Flange Bolts
Flange bolt ke sekoahelo se khoele se nang le letlapa le pharaletseng le kopantsoeng ka tlas'a hlooho ea hexagonal. Flange ena e aba moroalo oa ho koala holim'a sebaka se seholoanyane, ho felisa tlhoko ea washer e arohaneng le ho fokotsa nako ea kopano. Flange e kopantsoeng e boetse e fana ka khanyetso e matlafalitsoeng ea ho lokoloha tlas'a vibrate, e leng taba ea bohlokoa maemong a boima a mangata.
Li-bolts tsa flange li entsoe ka mefuta e 'meli e sarolohileng le e sa tsitsang. Liboutu tsa serethe li na le meno a ka tlas'a leqhubu a tšoarang bokaholimo ba ho tlolelana, 'me a fana ka ts'ebetso e phahameng ea ho thibela ho sisinyeha. Liphetolelo tse sa tsitsang li fana ka sebaka se boreleli, se loketseng lits'ebetso moo tšenyo ea bokaholimo e tlamehang ho fokotsoa.

3.Dacromet Coating Technology
Dacromet ke thekenoloji e tsoetseng pele e thehiloeng holim'a metsi, e se nang electrolytic holim'a metsi e qalileng ho sebetsana le mefokolo ea galvanizing e tloaelehileng. Ho roala ho na le li-zinc flakes, li-flakes tsa aluminium, le metsoako ea chromate e qhalakantsoeng ka har'a tsamaiso e nang le metsi. Ha li sebelisoa le ho phekoloa, li-flakes tsena li etsa mokoallo o teteaneng, o nang le lesela le fanang ka tšireletso e ikhethang ea ho senya ntle le kotsi ea ho embrittlement ea haedrojene.
Ts'ebetso ea ho roala ka Dacromet e fapana haholo le electroplating. Sebakeng sa ho kenya tšepe ka electrolysis, Dacromet e sebelisa sesebelisoa sa dip-spin kapa spray se lateloang ke pheko e phahameng ea mocheso. Nakong ea ho phekola hoo e ka bang likhato tse 280-320 tsa Celsius, zinki le aluminium flakes li kopana 'me li tlamahana le karoloana ea tšepe ka mochine o kopanyang chromate-mediated cross-linking. Sekoahelo se hlahisoang se tšesaane (hangata 6-10 microns), se ts'oanang, 'me se khomarela ka ho fetisisa.

5. Likopo tsa indasteri
Dacromet coated flange bolts e fumana ts'ebeliso e pharaletseng ho pholletsa le liindasteri tse ngata moo botšepehi ba sebopeho le ts'ireletso ea nako e telele ea kutu li bohlokoa haholo:
Indasteri ea Likoloi: E sebelisoa likopanong tsa chassis, lisebelisoa tsa enjine, litsamaiso tsa mariki, le likarolo tse emisitsoeng moo ho tiisang matla a phahameng ho kopantsoeng le ho hanyetsa ha letsoai ho bohlokoa. Li-OEM tse kholo li hlakisa li-fasteners tse koahetsoeng ka Dacromet bakeng sa lits'ebetso tse ka tlas'a lefatše tse pepeselitsoeng letsoai le mongobo tseleng.
Kaho le Mehaho ea Motheo: Ho sebelisoa likhokahanyo tsa sebopeho sa tšepe, likarolo tsa borokho, le lisebelisoa tsa kantle moo moralo o ikemetseng o fokotsang nako ea ho kenya le ho roala ha Dacromet ho fana ka ts'ebeletso e sa lefelloeng ea lilemo tse mashome.
Marine le Offshore: Ho hanyetsa ha letsoai ka mokhoa o ikhethang oa ho roala ha Dacromet (ho fihla ho lihora tse 3,000) ho etsa hore liboutu tsena e be tse loketseng bakeng sa kaho ea likepe, lipolanete tse lebopong la leoatle, le lisebelisoa tsa boema-kepe tse pepesehileng tikolohong e tsoelang pele ea metsi a letsoai.
Matla a Moea: E sebelisoa ka har'a tora ea turbine flanges le likopanong tsa nacelle moo bolting e matla haholo e tlamehang ho mamella phallo ea cyclic le ho pepeseha tikolohong nakong ea bophelo ba ts'ebeletso ea lilemo tse 20+.
Terene le Mechini e Boima: E sebelisoa litsing tsa ho tiisa seporo, likarolo tsa terene, le lisebelisoa tsa merafo moo ho hanyetsanang le ho thothomela le ts'ireletso ea kutu li hlokahalang ka nako e le 'ngoe.
