2026-08-17

Isishwankathelo soBuchule esiBanzi seDacromet Surface Treatment kunye neSocket Head Cap Screw Specifications

1. Intshayelelo

I-Dacromet-coated hex socket head cap screws ehambelana nomgangatho we-DIN 912 imele isisombululo esiphezulu sokusebenza esidibanisa ukugqwesa komatshini we-screws ye-socket head cap echanekileyo kunye ne-corrosion resistance resistance ye-Dacromet surface treatment. Ezi zibophelelo zisetyenziswa ngokubanzi kwiimoto, ulwakhiwo, elwandle, kumandla omoya, kunye nezicelo zoomatshini boshishino apho zombini imfezeko yesakhiwo kunye nokhuseleko lomhlwa lwexesha elide lubalulekile.

Eli nqaku libonelela ngenkcazo ebanzi yobugcisa kwiimbono ezimbini: inkqubo yokwaleka kweDacromet, enika ezi ziqhoboshi iimpawu zazo ezikhethekileyo zokuchasa umhlwa, kunye ne-DIN 912 socket head cap screw geometry, echaza uyilo lwazo lomatshini kunye nemigangatho yobukhulu.

2. I-Dacromet Coating Technology

I-Dacromet yitekhnoloji ephucukileyo, esekwe emanzini, ehambelana nokusingqongileyo echasene nomhlwa ephuhliswe njengenye indlela ye-electroplating yemveli. Yinkqubo yokugquma i-non-electrolytic dip spin eyenziwe ngeeflakes ze-zinc ze-ultra-fine, iiflakes ze-aluminium, iikhompawundi ze-chromic acid, kunye nezibophelelo ezikhethekileyo ze-organic. Xa zinyangwa kumaqondo obushushu aphakamileyo, la malungu enza i-metallic exineneyo, i-multi-layered coating edibanisa i-metallurgically kwi-substrate yentsimbi.

Ngokungafaniyo ne-electroplating eqhelekileyo, exhomekeke kwi-electrolytic deposition, i-Dacromet isebenzisa inkqubo ye-dip-spin okanye i-dip-drain. Iifasteners zintywiliselwa kwi-Dacromet liquid coating, emva koko zifakwe kwi-centrifuged ukususa izinto ezingaphezulu, kwaye ekugqibeleni zibhakwe malunga ne-300 degrees Celsius. Le nkqubo yokunyanga ibangela ukuba i-zinc kunye ne-aluminiyam flakes i-laminate kunye ne-sinter kunye, ukudala isilivere-grey, umaleko okhuselayo obambelela kakhulu.

Inkqubo yokugquma iDacromet inezigaba ezininzi ezilawulwa ngononophelo:

Inyathelo	Inkqubo	Inkcazo
1	Ukunciphisa amafutha	Ukususwa kweoli, i-lubricant, kunye ne-surface contaminants usebenzisa i-alkaline agents zokucoca
2	Shot Blasting	Ukucoca ngoomatshini ukususa isikali, umhlwa, kunye noomaleko be-oxide ukusuka kumphezulu wokuqinisa
3	Dip-Spin Coating	Ukuntywiliselwa kwiDacromet yolwelo ukutyabeka kulandele centrifugal ukusonta ukulawula ukutyeba yokwambathisa
4	Ukunyangwa kokuQala	Ukubhaka kwi-80-120 degrees Celsius ukukhupha umswakama kwaye wenze ifilimu yokuqala
5	Okwesibini Dip-Spin	Umaleko wokugquma wesibini ozikhethelayo wokhuseleko lomhlwa
6	Ukunyangwa kokugqibela	Ukubhaka kwi-280-320 degrees Celsius ukuya kwi-sinter zinc / aluminium flakes kwaye wenze umaleko wokugqibela okhuselayo.
7	Ukupholisa kunye noHlolo	Ukupholisa okulawulwayo okulandelwa kukuhlolwa komgangatho wobunzima bokugquma, ukuncamathela, kunye nenkangeleko

3. DIN 912 Socket Head Cap Izikrufu

I-DIN 912 nguMgangatho woShishino waseJamani ochaza imilinganiselo, unyamezelo, kunye neempawu zomatshini zehex socket head cap screws, ekwaziwa ngokuba zii-Allen bolts okanye izikrufu zesocket head cap. Ezi zibophelelo zibonakalisa intloko ye-cylindrical ene-hexagonal socket drive, eyenzelwe ukuba iqhutywe yi-Allen wrench (i-hex key). Umgangatho we-DIN 912 wamkelwe ngokubanzi kumazwe ngamazwe kwaye usebenza ngokulinganayo ne-ISO 4762.

Izikrufu zentloko yesokethi ziphawulwa ngamandla azo amakhulu ukuya kubungakanani. Uyilo lwentloko ye-cylindrical luvumela amandla aphezulu okubamba xa kuthelekiswa nezikrufu zentloko ze-hex zedayamitha efanayo, ngelixa i-hex drive yangaphakathi ivumela ukufakwa kwiindawo ezivaliweyo kunye nokukhutshwa okulinganiselweyo. Intloko ihlala igungxulwe kunye okanye ngaphantsi kwendawo yokukhwelana xa ifakwe kumngxunya obambeneyo, inika inkangeleko ecocekileyo, ephantsi.
