I-Dacromet Hex Bolts: I-Superior Corrosion Resistance kanye Nokusebenza Okuhlala Isikhathi Eside 

3. Inqubo ye-Dacromet Coating yama-Hex Bolts

Ukukhiqizwa kwe I-Dacromet hex bolts ilandela inqubo elawulwa ngokucophelela engeyona eye-electrolytic eqinisekisa ukumbozwa okufanayo futhi iqede ubungozi bokufakwa kwe-hydrogen:

1. Ukulungiswa kwendawo: Hex amabhawodizihlanzwa kahle ukuze kukhishwe uwoyela, amafutha, isikali, nokungcola ukuze kuqinisekiswe ukunamathela okufanele I-Dacromet

2.Ukufaka isicelo: Kuhlanziwe amabhawodibacwiliswa odaka olusekelwe emanzini lwezinc namaflake e-aluminium anezibophezelo. Izindlela ze-dip-spin noma zesifutho ziqinisekisa ngisho nokunamathela kuzo zonke izindawo ze-hexagonal amabhawodi, okuhlanganisa imicu nezinsika.

3. Ukwelapha: Ngemuva kokususwa kwe-slurry eyengeziwe, i-coated amabhawodizibhakwa cishe ku-300°C. I-inorganic binder iqinisa futhi ibophe ama-flakes e-zinc-aluminium ensimbi, yenze isivikelo. I-Dacromet

4.Ukuhlola: Kuqediwe Amabhawodi e-Dacrometzihlolelwa ukujiya kwe-coating, ukubukeka, ukunamathela, kanye ukumelana nokugqwala. Amajazi angaphezulu angawakhethela angathuthukisa ukuthambisa noma umbala.

Ngoba i I-Dacromet inqubo kuhilela akukho pickling acid noma electrolytic deposition, abukho ubungozi hydrogen embrittlement. Lokhu kwenza I-Dacromet ifaneleka ikakhulukazi i-hex yamandla aphezulu amabhawodi amabanga 8.8, 10.9, kanye nele-12.9.

4. Izinzuzo Eziyinhloko Ze-Dacromet Hex Bolts

I-Dacromet hex bolts iletha inhlanganisela eyingqayizivele yezinzuzo zokusebenza ezibenza bahluke kumagalani avamile noma amapuleti amabhawodi:

4.1 Ukumelana Nokugqwala Okuvelele

Isici esibaluleke kakhulu se I-Dacromet (I-Darcomet) iyingqayizivele anti-ukugqwala amandla. Okujwayelekile Amabhawudi ahlanganiswe nge-Dacromet ngokuvamile zuza ngaphezu kwamahora angu-1,000 wokumelana nesifutho sikasawoti ngaphandle kokugqwala okubomvu; amamaki asebenza kahle kakhulu angadlula amahora angu-2,000. Uma kuqhathaniswa ne-electro-galvanizing evamile, Amabhawodi e-Dacromet nikela izikhathi ezi-7 kuye kweziyi-10 kangcono ukuvikela ukugqwala. Ngisho nasezivivinyweni ze-cyclic corrosion nasezindaweni ze-sulphur dioxide, I-Dacromet hex bolts gcina ubuqotho obuhle kakhulu.

4.2 Akukho I-Hydrogen Embrittlement

Amandla aphezulu amabhawodi zisengozini yokufakwa kwe-hydrogen lapho zicutshungulwa yi-electroplating evamile. I I-Dacromet inqubo igwema ngokuphelele le ngozi ngoba akuyona electrolytic. Ngenxa yalokho, I-Dacromet hex bolts amabanga aphezulu aqinile ahlala ephephile futhi ethembekile ngaphansi komthwalo, okuwenza alungele izinhlelo zokusebenza ezibucayi zesakhiwo nezimoto.

4.3 Ukumelana Nokushisa Okuhle Kakhulu

I-Dacromet ama-coatings ahlala azinzile emazingeni okushisa afinyelela ku-300 ° C noma ngaphezulu. Izindwangu zendabuko ze-zinc ziqala ukuqhekeka noma ukulahlekelwa ukumelana nokugqwala ngaphezu kuka-70–100°C futhi ingase yehluleke ku-200–300°C. Ngokuphambene, Amabhawudi ahlanganiswe nge-Dacromet gcina kokubili ukubonakala nokusebenza okuvikelayo ngaphansi kokuchayeka isikhathi eside kumazinga okushisa aphezulu—okuyigugu ezingxenyeni zenjini, amasistimu wokukhipha umoya, namathuluzi ezimboni.

4.4 Ukungena Okuphakeme Nefilimu Encane

Uhlelo lokusebenza lwe-dip-spin lwe I-Dacromet iqinisekisa ukuthi i-coating ingena ezindaweni ezijulile, izintambo, nezimbobo eziyimpumputhe ze-hex amabhawodi. Ngobukhulu obujwayelekile obungu-6-10 μm kuphela, i I-Dacromet ifilimu ayiguquli kakhulu ubukhulu bentambo, ivumela I-Dacromet hex bolts ezosetshenziswa namantongomane ajwayelekile. Lokhu permeability okuphezulu kunikeza okuphelele anti-ukugqwala isivikelo ngisho nakumajiyometri ayinkimbinkimbi.

4.5 Ukunamathela Okuhle kanye Nokukwazi ukuphindeka futhi

I-Dacromet ama-coatings anamathela ngokuqinile ku-substrate yensimbi futhi amukele amajazi angaphezulu noma amapende engeziwe kahle kakhulu. Lokhu kuvumelana nezimo kusekela ama-coefficients enziwe ngezifiso kanye nokufakwa kwekhodi kombala ochungechungeni oluhlukile lwe amabhawodi.

5. Izicelo ze-Dacromet Hex Bolts

Siyabonga kumphathi wabo ukumelana nokugqwala nokwethembeka, I-Dacromet hex bolts zicaciswa kabanzi kuzo zonke izimboni eziningi:

Izimoto nezokuthutha: I-chassis, ukumiswa, umzimba, nenjini amabhawodiedinga isikhathi eside anti-ukugqwala ukusebenza ngaphansi kosawoti womgwaqo kanye nokuchayeka kwesimo sezulu.

Ukwakhiwa nengqalasizinda: Okwesakhiwo amabhawodiamabhuloho, imibhoshongo, izintambo zokuthutha, nezakhiwo ezingasogwini lapho I-Dacromet ukuvikela kwandisa kakhulu impilo yesevisi.

Osolwandle nasogwini: Hex amabhawodiesetshenziswa emikhunjini, ezisekelweni zasogwini, kanye nempahla yasechwebeni izuza ekumelaneni okuvelele kwe-salt-spray I-Dacromet.

Amandla avuselelekayo: Kusetshenziswa imibhoshongo ye-turbine yomoya kanye nezinhlelo zokukhweza ilanga Amabhawudi ahlanganiswe nge-Dacrometokwethembekile ngaphandle ukuvikela ukugqwala.

Imishini yezimboni: Amandla aphezulu amabhawodiezitshalweni zamakhemikhali, ukukhiqiza amandla, kanye nemishini esindayo kuncike kuyo I-Dacromet ukuze iqine ezimeni ezigqwalile.
