1. Intshayelelo

I-Dacromet-coated hex bolts socket bolts imele isisombululo esiphezulu sokusebenza esidibanisa ubuchwepheshe obubini obubalulekileyo: inkqubo ye-Dacromet ephezulu yokugqoka indawo kunye ne-precision-engineered cylindrical head hex socket (Allen) drive design. Ezi bhotshi zisetyenziswa ngokubanzi kwiimoto, ulwakhiwo, ulwandle, kunye nezicelo zoshishino apho ukuxhathisa okuphezulu kwe-corrosion kunye nokudluliselwa kwe-torque okuthembekileyo kuyimfuno ebalulekileyo.

Esi sikhokelo sobugcisa sibonelela ngovavanyo olunzulu lweteknoloji ye-Dacromet yokugqoka kunye noyilo lwesakhiwo se-cylindrical head hex socket bolts, ukugubungela ukubunjwa kwezinto zabo, iinkqubo zokuvelisa, iimpawu zokusebenza, kunye nokusetyenziswa okusebenzayo.

2. I-Dacromet Coating Technology

2.1 Yintoni iDacromet?

I-Dacromet yitekhnoloji ephucukileyo, ehambelana nokusingqongileyo echasene nomhlwa ephuhliswe njengenye indlela yangoku kwi-electroplating yemveli. Yinkqubo yokwambathisa esekwe emanzini, engeyiyo i-electrolytic eyenziwe nge-ultrafine zinc kunye ne-aluminium flakes edityaniswe kunye ngenkqubo yokuguqulwa kwechromate. Ukugquma kusetyenziswe ngeendlela ze-dip-spin okanye iindlela zokutshiza kwaye zinyangelwe kumaqondo obushushu ajikeleze i-300 ° C, zenza ifilimu ekhuselweyo, enemigangatho emininzi ekhuselayo kwi-substrate yesinyithi.

2.2 Ukubunjwa kunye neSakhiwo sokuNgquma

I-Dacromet yokwambathisa iqulathe amacandelo aphambili aliqela asebenza ngokubambisana ukubonelela ngokhuseleko olukhethekileyo lomhlwa:

I-Zinc flakes (20-30%): Ukubonelela ngokhuseleko lwedini (cathodic) kwi-substrate yensimbi

Iiflakes ze-aluminium (10-15%): Ukuphucula ukukhuselwa komqobo kunye nokumelana nobushushu

Isibophelelo seChromate: Yenza umaleko oguqukileyo ovalayo

Isithuthi esinyibilikayo se-Organic: Sithwala amacandelo aqinileyo ngexesha lokufaka isicelo

2.3 I-Dacromet vs. IiCoatings eziqhelekileyo

Le theyibhile ilandelayo ithelekisa iDacromet kunye neetekhnoloji eziqhelekileyo zokugquma ngebholiti:

3. I-Cylindrical Head Socket Bolt Design

3.1 Iimpawu zoLwakhiwo

I-cylindrical head hex socket bolt, ngokuqhelekileyo ibhekisela phantsi kwe-DIN 912 (ISO 4762), ibonisa intloko ye-cylindrical (iqhosha) kunye ne-hexagonal socket (Allen) drive recess. Olu luyilo lubonelela ngeenzuzo ezininzi zolwakhiwo ngaphezulu kweebholiti zentloko zehex eziqhelekileyo:

Uyilo lwentloko ephantsi: Intloko ye-cylindrical ihlala igungxulwa okanye ingaphantsi kancinci kumphezulu, iyenza ilungele iindibano ezixineneyo ezinokukhutshwa okulinganiselweyo.

I-hex drive yangaphakathi: I-hex socket ivumela i-torque ukuba isetyenziswe ngaphakathi kwentloko, ukunciphisa umngcipheko wokuhluthwa kunye nokwenza amandla aphezulu okubamba.

Umphandle ogudileyo wangaphandle: Ukungabikho kweeflethi ze-hex zangaphandle kuthintela ukuphazamiseka kumacandelo akufutshane kunye nokuphucula inkangeleko yobuhle.

Ukusabalalisa okufanayo koxinzelelo: Ijiyometri yentloko yecylindrical isasaza umthwalo obambekayo ngokulinganayo kwindawo yoqhagamshelwano, inciphisa ukugxininiswa koxinzelelo lwasekhaya.

4. Usetyenziso kunye nokuSetyenziswa kweShishini

Iibholiti zesokethi ze-hex ezigqunywe nge-Dacromet zifumana ukusetyenziswa okubanzi kuwo wonke amashishini amaninzi ngenxa yokudityaniswa kwawo okukodwa kokuxhathisa umhlwa kunye nokuthembeka koomatshini:

Iimoto: Iindibano ze-injini, izixhobo ze-chassis, iinkqubo zebrake, kunye neepaneli zomzimba apho ukhuseleko lwexesha elide luyimfuneko.

Ulwakhiwo kunye neziseko ezingundoqo: Uqhagamshelo lwesakhelo sentsimbi, iisistim zodonga lwekhethini, kunye neendibano zezakhiwo zangaphandle ezivezwe kwimozulu embi.

Ulwandle kunye nonxweme: Izixhobo kunye nezakhiwo eziphantsi kokuvezwa kwamanzi etyuwa, apho iingubo eziqhelekileyo zisilela ngokukhawuleza.

Umzila kaloliwe kunye namandla omoya: Iindawo ezishukumayo eziphezulu ezifuna ukuqiniswa okukhuselekileyo kunye nokhuseleko lomphezulu olomeleleyo.

Iindawo ezivaliweyo zombane kunye ne-elektroniki: Iikhabhathi zangaphandle kunye nezindlu zezixhobo ezifuna izibophelelo ezingaqhubekiyo, ezikwaziyo ukubola.

6.Isiphelo

Iibholiti zesokethi ze-hex ezigqunywe yi-Dacromet zimele ukuhlangana kobunjineli bomphezulu ophambili kunye noyilo oluchanekileyo lomatshini. Ingubo ye-Dacromet ihambisa ukhuseleko olukhethekileyo lwe-corrosion ngaphandle kwemingcipheko ye-hydrogen embrittlement ehambelana ne-electroplating, ngelixa i-cylindrical head hex socket configuration ibonelela ngokugqithiswa kwe-torque ephezulu, i-geometry edibeneyo, kunye nokusebenza okuthembekileyo kwe-clamping. Ngokudibeneyo, obu buchwepheshe benza iibholiti ze-Dacromet hex ukuba zibe lukhetho olufanelekileyo lokufuna izicelo kuwo wonke amacandelo eemoto, ezokwakha, ezaselwandle, kunye nakwezoshishino.

Njengoko amashishini aqhubeka efuna ubomi obude benkonzo, ukugcinwa okuncitshisiweyo, kunye nokuveliswa koxanduva lokusingqongileyo, ukwamkelwa kweefasteners ezifakwe kwi-Dacromet kulindeleke ukuba kukhule. Iinjineli kunye neengcali zokuthengwa kwempahla kufuneka ziqwalasele ukukhankanya iibholiti ze-Dacromet hex kuso nasiphi na isicelo apho ukuxhathisa ukubola, ukuthembeka koomatshini, kunye noyilo lwendibano edibeneyo ziyimilinganiselo ephambili yokusebenza.
