Iibhotshi ze-Dacromet ze-Hex: Ukuchasana kwe-Corrosion ephezulu kunye nokuSebenza okuhlala ixesha elide 

3. Inkqubo yeDacromet yokuBiyela yeeBolt zeHex

Imveliso ye Iibholiti ze-Dacromet hex ilandela inkqubo elawulwa ngononophelo engeyiyo eye-electrolytic eqinisekisa ukugqunywa ngokufanayo kwaye ishenxise imingcipheko ye-hydrogen embrittlement:

1.Ukulungiswa komphezulu: Hex iibholitizicocwe ngokucokisekileyo ukuze zisuse ioyile, igrisi, isikali, kunye nezingcolisi ukuqinisekisa ukuncamathela okukuko kokulungileyo. Dacromet

2. Ukusetyenziswa kokugquma: Icociwe iibholitibantywiliselwa kwi-slurry esekelwe emanzini ye-zinc kunye ne-aluminium flakes enezibophelelo. Iindlela zeDip-spin okanye zokutshiza ziqinisekisa ukugquma kuyo yonke imiphezulu yehexagonal iibholiti, kubandakanywa imisonto kunye namakhefu.

3. Ukunyanga: Emva kokuba i-slurry engaphezulu isusiwe, ifakwe iibholitizibhakwa malunga ne-300 ° C. I-inorganic binder iqinisa kwaye ibophe iiflakes ze-zinc-aluminiyam kwintsimbi, yenze into ekhuselayo. Dacromet

4.Uhlolo: Kugqityiwe Iibholithi zeDacrometzikhangelwa ukutyeba, inkangeleko, ukuncamathela, kunye ukumelana nomhlwa. Iidyasi ezikhethiweyo zinokwandisa ukuthambisa okanye umbala.

Ngenxa yokuba Dacromet inkqubo ibandakanya akukho pickling asidi okanye electrolytic deposition, akukho mngcipheko hydrogen embrittlement. Oku kwenza Dacromet ilungele ngakumbi iheksi ephezulu yamandla iibholiti yamabanga 8.8, 10.9, kunye ne-12.9.

4. Izinto eziluncedo eziphambili zeDacromet Hex Bolts

Iibholiti ze-Dacromet hex hambisa indibaniselwano eyodwa yeenzuzo zokusebenza ezibenza bahluke kwigalvanized eqhelekileyo okanye ecwecwe iibholiti:

4.1 UKuxhathisa okugqwesileyo kuMhlwa

Olona phawu lubalulekileyo lwe Dacromet (I-Darcomet) yinto ekhethekileyo anti-umhlwa ubunakho. Umgangatho Iibholiti ezifakwe kwi-Dacromet ngokuqhelekileyo ukufikelela kwiiyure ezili-1,000 zokuxhathisa isitshizi setyuwa ngaphandle komhlwa obomvu; amabanga akumgangatho ophezulu angagqitha iiyure ezingama-2,000. Xa kuthelekiswa ne-electro-galvanizing yesiko, Iibholithi zeDacromet nikela 7 ukuba 10 amaxesha ngcono ukhuseleko lomhlwa. Kwanakwiimvavanyo ze-cyclic corrosion kunye ne-sulphur dioxide, Iibholiti ze-Dacromet hex gcina ingqibelelo ebalaseleyo.

4.2 Akukho UkuGqibezwa kweHydrojeni

Amandla aphezulu iibholiti basemngciphekweni we-hydrogen embrittlement xa kusetyenzwa nge-electroplating eqhelekileyo. I Dacromet inkqubo iphephe ngokupheleleyo lo mngcipheko ngenxa yokuba ayikho electrolytic. Ngenxa yoko, Iibholiti ze-Dacromet hex amabanga aphezulu ahlala ekhuselekile kwaye ethembekile phantsi komthwalo, oko kubenza balungele usetyenziso olubalulekileyo lwesakhiwo kunye nemoto.

4.3 Ukumelana nobushushu okugqwesileyo

Dacromet Iingubo zihlala zizinzile kumaqondo obushushu ukuya kuma-300 ° C okanye ngaphezulu. Iingubo ze-zinc zendabuko ziqala ukuqhekeka okanye ukulahlekelwa ukumelana nomhlwa ngaphezulu kwe-70–100°C kwaye inokusilela kuma-200–300°C. Ngokwahlukileyo, Iibholiti ezifakwe kwi-Dacromet gcina zombini imbonakalo kunye nokusebenza okukhuselekileyo phantsi kokuvezwa kobushushu obuphezulu-okuxabisekileyo kumagumbi enjini, iinkqubo zokukhupha umoya, kunye nezixhobo zoshishino.

4.4 Ukungena okuPhezulu kunye neFilimu eNcinci

Usetyenziso lwe-dip-spin ye Dacromet iqinisekisa ukuba i-coating ingena kwiindawo ezinzulu, iintambo, kunye nemingxuma eyimfama ye-hex iibholiti. Ngobunzima obuqhelekileyo be-6-10 μm kuphela, i Dacromet ifilimu ayitshintshi kakhulu imilinganiselo yomsonto, ivumela Iibholiti ze-Dacromet hex ukuba isetyenziswe ngamandongomane asemgangathweni. Le permeability ephezulu ibonelela ngokupheleleyo anti-umhlwa ukhuseleko nakwiijiyometri ezintsonkothileyo.

4.5 Ukuncamathela okuLungileyo kunye nokuPhinda uKukholeka

Dacromet iingubo zibambelela ngokuqinileyo kwi-substrate yentsimbi kwaye zamkele iingubo ezongezelelweyo zezinto eziphilayo okanye iipeyinti kakuhle. Olu bhetyebhetye luxhasa i-friction coefficients elungiselelweyo kunye nekhowudi yombala kuthotho olwahlukileyo lwe iibholiti.

5. Ukusetyenziswa kweDacromet Hex Bolts

Enkosi kubo ophakamileyo ukumelana nomhlwa kunye nokuthembeka, Iibholiti ze-Dacromet hex zichazwe ngokubanzi kumashishini amaninzi:

Izithuthi kunye nezothutho: I-chassis, ukumiswa, umzimba, kunye ne-injini iibholitikufuna ixesha elide anti-umhlwa ukusebenza phantsi kwetyuwa yendlela kunye nokuvezwa kwemozulu.

Ulwakhiwo kunye nezibonelelo: Ulwakhiwo iibholitiiibhulorho, iinqaba, iintambo zothumelo, kunye nezakhiwo eziselunxwemeni apho Dacromet ukhuseleko lwandisa kakhulu ubomi benkonzo.

Ezaselwandle naselwandle: Hex iibholitiezisetyenziswa kwiinqanawa, amaqonga offshore, kunye nezixhobo izibuko inzuzo ebalaseleyo ukuxhathisa ityuwa-spray of Dacromet.

Amandla ahlaziyekayo: Iinqaba zeinjini yomoya kunye neenkqubo zokunyuswa kwelanga ziyasebenza Iibholiti ezifakwe kwi-Dacrometyangaphandle ethembekileyo ukhuseleko lomhlwa.

Oomatshini bemizi-mveliso: Amandla aphezulu iibholitikwizityalo zemichiza, ukuveliswa kwamandla, kunye noomatshini abanzima bathembele Dacromet ukwenzela ukuhlala ixesha elide kwiimeko ezidliwayo.
