I-Dacromet Coated Flange Bolts-IsiKhokelo soBugcisa esiBanzi sokuYila, iTekhnoloji yoKutyabeka, kunye nosetyenziso lwezoShishino
2026-08-12
1. Intshayelelo
Iibholiti ze-Flange zibonisa udidi olubalulekileyo lwezibophelelo zoshishino, ukudibanisa ukusebenza kwebholithi eqhelekileyo kunye ne-washer-efana ne-flange edibeneyo phantsi kwentloko ye-bolt. Xa zidityaniswe netekhnoloji yokugquma i-Dacromet, ezi zibophelelo zifezekisa ibhalansi ekhethekileyo yamandla omatshini kunye nokuxhathisa ukubola, okuzenza zibe yimfuneko kwiimeko ezifunwayo ezifana nokuveliswa kweemoto, ukwakhiwa, ubunjineli baselwandle, kunye noomatshini abanzima.
Eli nqaku libonelela ngovavanyo olucacileyo lwe-Dacromet coated flange bolts ukusuka kwiimbono ezimbini ezongezelelweyo: uyilo lwesakhiwo kunye neepropathi zemishini yeebholiti ze-flange, kunye neteknoloji yonyango ephezulu eyaziwa ngokuba yiDacromet. Ngokudibeneyo, ezi zinto zichaza isisombululo se-fastener esihlangabezana neemfuno ezingqongqo zezicelo zobunjineli bale mihla.
2. Ukuqonda iiBolts zeFlange
Ibhawudi yeflange sisiqhoboshelo esinentambo ebanzi edityaniswe ngokuthe ngqo phantsi kwentloko ene-hexagonal. Le flange isasaza umthwalo obambezelayo kwindawo enkulu, isusa imfuno yewasha eyahlukileyo kunye nokunciphisa ixesha lokuhlanganisa. Iflange edityanisiweyo ikwabonelela ngokuxhathisa okongeziweyo ekukhululeni phantsi kokungcangcazela, uqwalaselo olubalulekileyo kwindawo yomthwalo oguqukayo.
Iibholiti ze-Flange zenziwa kuzo zombini iindidi ezirhwebisiweyo nezingafakwanga. Iibholiti zeflange eziserrated zinezinyo kumzantsi weflange ezibamba umphezulu wokukhwelana, zibonelela ngokusebenza okuphezulu kokuchasana nokungcangcazela. Iinguqulelo ezingafakwanga zinika umphezulu wokuthwala ogudileyo, olungele izicelo apho umonakalo womphezulu kufuneka uncitshiswe.

3.ITekhnoloji yoKugquma iDacromet
I-Dacromet yitekhnoloji ephuculweyo esekwe emanzini, engeyiyo i-electrolytic surface coating eyaphuhliswa ekuqaleni ukujongana nemida yokwenziwa kwegalvanizing eqhelekileyo. Ukwaleka kuqulathe iiflakes ze-zinc, iiflakes ze-aluminiyam, kunye neekhompawundi zechromate ezisasazwe kwinkqubo yokubopha amanzi. Xa zisetyenziswa kwaye zinyangwa, ezi flakes zenza umqobo oshinyeneyo, omaleko obonelela ngokhuseleko olukhethekileyo lokutya ngaphandle komngcipheko we-hydrogen embrittlement.
Inkqubo yokugquma iDacromet ihluke ngokusisiseko kwi-electroplating. Kunokuba ifake isinyithi nge-electrolysis, i-Dacromet isebenzisa i-dip-spin okanye i-spray application elandelwa kukunyanga kobushushu obuphezulu. Ngexesha lokunyanga malunga ne-280-320 degrees Celsius, i-zinc kunye neeflakes ze-aluminiyam zidibanisa kunye kwaye zibophe kwi-substrate yentsimbi ngokusebenzisa indlela yokudibanisa i-chromate-mediated cross-linking. Isiphumo sokwaleka sibhityile (ngokuqhelekileyo i-6-10 microns), iyunifomu, kwaye ibambelela ngokugqithisileyo.
3.1 Isishwankathelo seNkqubo yokuNgquma
Inkqubo yesicelo seDacromet ibandakanya izigaba ezininzi ezilawulwa ngokuchanekileyo, nganye inegalelo kwiimpawu zokugqibela zokusebenza kwengubo:
Itheyibhile 2. Dacromet Coating Inkqubo Amanyathelo
| Inyathelo | Inkqubo | Inkcazo |
| 1 | Unyango lwangaphambili | Ukunciphisa, ukudubula ukudubula, kunye nokucocwa kwe-ultrasonic ukususa ioli, isikali, kunye nokungcola kwi-bolt surface. |
| 2 | Ukudipha / Ukutshiza | Iibholiti zicwiliswa okanye zitshizwe ngesisombululo se-Dacromet yamanzi e-coating equkethe i-zinc kunye ne-aluminium flakes. |
| 3 | Spin Ukomisa | I-Centrifugal spinning isusa i-coating engaphezulu ukuqinisekisa ubukhulu obufanayo (i-6-10 microns). |
| 4 | Ukunyanga | Ibhaka kwi-280-320C yemizuzu engama-20-30, i-flakes edibeneyo kwi-substrate nge-sintering. |
| 5 | Idyasi yesibini | Umjikelo wesibini wokudipha kunye nokunyanga usetyenziswa ekukhuseleni ukuthotywa okuphuculweyo (ukhetho lokwaleka obunzima). |
| 6 | Ukunyangwa kokugqibela | Ukubhaka kokugqibela kwi-300C kuqinisekisa ukudibanisa okupheleleyo kunye nokunamathela okuphezulu kwengubo. |
Yonke le nkqubo idla ngokugqityezelwa kwimijikelo emibini yokwaleka ukuze kuphunyezwe ubukhulu obufunwayo bokugquma kunye nokumelana nomhlwa. Umjikelo ngamnye unesicelo, ukomisa, kunye nokunyanga, kunye nemveliso yokugqibela ebonisa imbonakalo yesilivere-ngwevu.
4.Izinto eziluncedo zeDacromet Coating
I-Dacromet yokwambathisa ibonelela ngeengenelo ezininzi ezahlukileyo kunyango oluqhelekileyo lomphezulu, iyenza ibe lolona khetho lukhethwayo kwizicelo zokuqhoboshela ezisebenza kakhulu:
I-Superior Corrosion Resistance: I-Dacromet-coated fasteners inokumelana ne-1,000 kwiiyure ze-3,000 zokuvavanya ityuwa yokutshiza (i-ASTM B117) ngaphambi kokubonakala kwe-rust ebomvu, ngokugqithisileyo i-electroplating yendabuko ye-zinc (iiyure ezingama-300-700).
Akukho ukunyanzeliswa kwe-Hydrogen: Ngokungafani ne-electroplating, inkqubo ye-Dacromet ayibandakanyi i-electrolysis, isusa umngcipheko we-hydrogen embrittlement. Oku kubaluleke kakhulu kwiibholiti zamandla aphezulu (i-Class 10.9 kunye ne-12.9) esetyenziswa kwizicelo ezikhuselekileyo zokhuseleko.
Ukuchasana nobushushu obugqwesileyo: Ubume be-inorganic of the Dacromet coating ivumela ukuba igcine iipropathi zayo ezikhuselayo kumaqondo obushushu ukuya kuthi ga kwi-300 degrees Celsius, igqithise kakhulu imida ye-thermal ye-organic coatings kunye ne-zinc plating eqhelekileyo.
Ukwaleka okufanayo: Indlela yesicelo se-dip-spin iqinisekisa ukutyeba okungaguquguqukiyo kokutyabeka nakwijometri ezintsonkothileyo, kubandakanywa iindawo ezinemisonto kunye neendawo zokuhlala apho i-electroplating inokuvelisa iidiphozithi ezingalinganiyo.
Ukuthotyelwa kokusiNgqongileyo: Imiqulu yeDacromet yanamhlanje ayinayo i-hexavalent chromium (Cr6 +), ithobela i-RoHS, i-ELV, kunye ne-REACH izikhokelo, ezenza zilungele ukusetyenziswa kwezithuthi kunye ne-electronics.
5. Izicelo zoShishino
I-Dacromet coated flange bolts ifumana ukusetyenziswa okubanzi kuwo wonke amashishini amaninzi apho zombini imfezeko yesakhiwo kunye nokukhuselwa kwexesha elide kubaluleke kakhulu:
Umzi-mveliso weemoto: Isetyenziswa kwiindibano ze-chassis, ukunyuswa kwe-injini, iinkqubo zebrake, kunye nezixhobo zokuxhoma apho ukuqina okuphezulu okudityaniswa nokuxhathisa isitshizi setyuwa kubalulekile. Ii-OEMs ezinkulu zicacisa iziqhoboshi ezigqunywe ngeDacromet kwizicelo eziphantsi komhlaba ezivezwe kwityuwa yendlela kunye nokufuma.
Ulwakhiwo kunye neZiseko: Kuqeshwe kwiidibansi zentsimbi, amacandelo ebhulorho, kunye nezixhobo zangaphandle apho i-self-distributing flange design inciphisa ixesha lokufakela kunye ne-Dacromet coating inikezela amashumi eminyaka yenkonzo yokulondoloza.
I-Marine ne-Offshore: Ukuxhathisa okukhethekileyo kokutshiza kwetyuwa kwi-Dacromet coating (ukuya kwiiyure ze-3,000) kwenza ezi bholithi zilungele ukwakhiwa kweenqanawa, amaqonga angaphesheya, kunye ne-dock hardware evezwe kwiindawo eziqhubekayo zamanzi anetyuwa.
Amandla omoya: Asetyenziswa kwi-turbine tower flanges kunye ne-nacelle assemblies apho i-bolting ephezulu kufuneka imelane nokulayishwa komjikelo kunye nokuvezwa kokusingqongileyo kwiminyaka engama-20+ yobomi benkonzo.
Umzila kaloliwe kunye noomatshini abanzima: Isetyenziswa kwiinkqubo zokuqinisa umzila, amacandelo e-locomotive, kunye nezixhobo zemigodi apho ukuxhathisa ukungcangcazela kunye nokukhusela umhlwa kufuneka ngaxeshanye.
