Stainless steel screws vs. carbon steel screws: U ka khetha tharollo e molemohali ea ho tiisa joang bakeng sa hau?

Lefapheng la kaho, tlhahiso ea mechine le tlhokomelo ea boenjiniere, khetho ea li-screws e ama ka ho toba ts'ireletso ea moralo, litšenyehelo tsa tlhokomelo le bophelo ba morero. Bareki ba bangata ba atisa ho oela bothateng: li-screws tsa tšepe tse sa hloekang li theko e boima, 'me li-screws tsa carbon steel li bonolo ho rusa - ho khetha joang? Joaloka moetsi oa li-fasteners ea hloahloa, Indasteri ea Nanning Aozhan e tla u thusa ho fumana tharollo e molemohali ka ho bapisa ts'ebetso + linyeoe tsa 'nete!

Phapang ea bohlokoa lipakeng tsa stainless steel le carbon steel screws

1. Corrosion resistance: senotlolo sa ho tseba bophelo ba ts'ebeletso

Likurufu tsa tšepe e sa hloekang (joalo ka 304/316) li na le chromium le nickel, tseo ka tlhaho li ka etsang lera le sireletsang oxide ho thibela mongobo, sefafatsi sa letsoai le ho bola ha lik'hemik'hale. Li-screws tsa tšepe tsa carbon li tla rusa ka likhoeli tse 6-12 sebakeng se mongobo, haholo-holo libakeng tse lebōpong la leoatle kapa liindasteri, moo sekhahla sa kutu se potlakileng.

Taba ea 'nete: Sebaka sa polokelo ea thepa se sebelisitse likurufu tsa tšepe ea carbon ho lokisa sebopeho sa tšepe. Ka mor'a lilemo tse 3, liphanele tsa marulelo li ile tsa theoha ka lebaka la mafome, 'me litšenyehelo tsa ho lokisa li feta US $ 50,000; athe ntlo ea polokelo e tšoanang e fetotsoeng ho li-screw tse 304 tsa tšepe e se nang mathata a ho bola ka lilemo tse 10.

2. Papiso ea matla: ha se maemo ohle a hlokang matla a phahameng ka ho fetisisa

Hangata li-screws tsa tšepe tsa carbon li na le matla a holimo (joaloka 8.8, 10.9), tse loketseng meaho e boima. Leha ho le joalo, matla a li-screws tsa tšepe tse sa hloekang (tse kang A2-70, A4-80) li ka finyella litlhoko tse ngata tsa kaho le tsa mechine. Ntle le haeba e le boemo bo feteletseng ba ho jara (joalo ka marokho, mechini e boima), ha ho na tlhoko ea ho lelekisa matla a phahameng haholo.

3. Tlhahlobo ea litšenyehelo: ho boloka chelete ka nako e khuts'oane khahlano le boleng ba nako e telele

Theko ea pele ea theko ea li-screws tsa carbon steel e tlase ho 30% -50% ho feta ea tšepe e sa hloekang, empa ho hlokahala phekolo e tloaelehileng ea ho thibela mafome kapa ho e nkela sebaka. Libakeng tse mongobo, tse nang le asiti le alkaline, litšenyehelo tse felletseng tsa potoloho ea bophelo ba li-screw tsa tšepe li tlase - ho felisa tlhokomelo khafetsa le tahlehelo ea nako.

Tataiso ea Khetho: Khetha ho latela maemo a kopo ea hau

Boemo ba ho khetha li-screw tsa carbon steel

1. Mehaho ea nakoana ea nakoana (kaho ea lipontšo, likabelo tsa nakoana)
2. Libaka tse omeletseng tsa ka tlung (mokhabiso oa ofisi, kopano ea thepa ea ka tlung)
3. Merero e baballang litšenyehelo haholo 'me e ka amohela ho nkeloa sebaka khafetsa

Boemo ba ho khetha li-screw tsa tšepe tse sa hloekang

1. Libaka tse pepesehang ka ntle (marulelo, litšiea, lipalangoang)
2. Mongobo o phahameng / libaka tse nang le letsoai le lengata (mehaho e lebopong la leoatle, likepe, limela tsa lik'hemik'hale)
3. Lijo le lisebelisoa tsa bongaka (li tlameha ho finyella litekanyetso tsa bohloeki)
4. Libaka tseo ho leng thata ho li hlokomela (mehaho e phahameng, liphaephe tse ka tlas'a lefatše)

Litharollo tse ikhethileng bakeng sa Nanning Aozhan

Re utloisisa litlhoko tse ikhethang tsa projeke ka 'ngoe, kahoo re fana ka:

1. Ts'ebeletso ea tlhahlobo ea lisebelisoa: e u thusa ho netefatsa hore na li-screw tse teng li loketse tikoloho ea hajoale
2. Tharollo ea tšebeliso e tsoakiloeng: sebelisa tšepe e sa hloekang bakeng sa likarolo tsa bohlokoa le tšepe ea carbon bakeng sa likarolo tseo e seng tsa bohlokoa ho ntlafatsa litšenyehelo
3. Ntlafatso ea kalafo ea holim'a metsi: Dacromet / hot-dip galvanizing ea li-screw tsa carbon steel ho lelefatsa bophelo

Ke hobane'ng ha u re khetha?

Lilemo tse 10+ tsa ho tsepamisa maikutlo tlhahisong ea li-fasteners, ho latela litekanyetso tsa ISO/GB/DIN

Ts'ehetsa litaelo tsa liteko tse nyane, netefatsa sephetho pele u reka thepa e ngata

Fana ka tlaleho ea tlhahlobo ea kotsi ea kutu ho qoba liphoso tsa khetho
