IBanga le-8.8 le-Oxide emnyama ye-Hex yeSokethi ye-Screws ye-Head Cap Screws-Isishwankathelo soBuchule boKhuseleko lwe-Corrosion kunye noYilo lweNtloko 

2. IBanga le-8.8 I-Black Oxide Gqiba: UkuKhuselwa koMhlwa

2.1 Yintoni i-Black oxide?

I-oksidi emnyama, ekwabizwa ngokuba yi-blackening, yingubo yokuguqulwa kweekhemikhali eveliswa ngokuphendula umphezulu wesinyithi esinentsimbi kunye nesisombululo se-alkaline oxidizing kumaqondo obushushu aphakamileyo (ngokuqhelekileyo i-140 ukuya kwi-150 degrees Celsius). Ngokungafaniyo neengubo zombane ezifana ne-zinc okanye i-Dacromet, ebeka i-metallic layer eyahlukileyo phezu kwe-substrate, i-oxide emnyama iguqula i-topmost layer yentsimbi ngokwayo ibe yi-magnetite (Fe3O4), i-oxide yentsimbi emnyama ezinzileyo. Isiphumo singumgangatho obhityileyo, omnyama-omnyama oye ube yinxalenye ebalulekileyo ye-fastener kunokuba i-add-on layer.

2.2 Inkqubo ye-Black oxide

Inkqubo eqhelekileyo ye-black oxide yezibophelelo zeBanga lesi-8.8 ibandakanya ezi zigaba zilandelayo:

Ukucoca kunye nokucoca i-alkaline ukususa ioli, ukusika ulwelo, kunye nezingcoliso zevenkile.

I-Acid pickling ukususa nayiphi na isikali somhlaba okanye umhlwa okhanyayo.

Ukuntywiliselwa kwibhafu ene-alkaline-oxidizing eshushu (malunga ne-141 degrees Celsius), apho umaleko wemagneti wenza kwimizuzu eyi-10 ukuya kwengama-20.

Ukuhlanjululwa kunye nokutywinwa ngeoli yokukhusela i-rust okanye i-wax, eyongeza i-oxide layer kunye nomqobo we-hydrophobic.

2.3 IiMpawu zokuNxhathisa ukonakala

Ngokwayo, i-black oxide layer incinci (malunga ne-0.5 ukuya kwi-1.5 micrometers) kunye ne-porous, oku kuthetha ukuba inika kuphela ukuxhathisa ukubola okuncinci xa kuthelekiswa ne-zinc plating okanye i-hot-dip galvanizing. Nangona kunjalo, xa idityaniswe neoli eyongezelelweyo yokuthintela umhlwa okanye i-wax, i-coating ifezekisa ukuxhatshazwa kwetyuwa engathathi hlangothi malunga ne-24 kwiiyure ze-96, kuxhomekeke kumgangatho we-sealant. Lo mgangatho wokhuselo ufanelekile kwimo yangaphakathi, elawulwa yimozulu, okanye indawo enomhlwa epholileyo apho isibophelelo singabonakali kumswakama othe ngqo okanye isitshizi setyuwa ixesha elide.

2.4 Izinto eziluncedo kunye nemida

1.Zero utshintsho lwedimensional: Ngenxa yokuba i-oxide layer ingaphantsi kwe-2 micrometers ubukhulu, i-oxide emnyama ayitshintshi ukunyamezela intambo. Iifasteners zeBakala 8.8 zigcina i-original Class 6g yazo, okwenza i-coating ilungele iindibano ezichanekileyo apho ukuphazamiseka kwentambo kufuneka kuphetshwe.

2.Ngexabiso: I-Black oxide lolona nyango lomphezulu lunoqoqosho olukhoyo, luxabisa kakhulu kune-zinc-nickel plating, i-Dacromet, okanye ezinye iindlela zentsimbi.

3.Akukho hydrogen embrittlement: Ngokungafaniyo ne-electroplating, inkqubo ye-oxide emnyama ayivelisi igesi ye-hydrogen, isusa umngcipheko we-hydrogen embrittlement. Oku kubalulekile kwiifasteners zeBakala 8.8 ezisebenza kumanqanaba aphezulu oxinzelelo.

4. Isibheno sobuhle: I-uniform matte-black finish ibonelela ngokucocekileyo, inkangeleko yobuchwephesha edibanisa iindibano ezinemibala emnyama kunye nokunciphisa ukukhanya okukhanyayo.

5.Umlinganiselo-Unyino wokuxhathisa umhlwa wangaphandle: I-oxide emnyama ayilungelanga ngaphandle, elwandle, okanye kwindawo enomhlwa kakhulu. Kwizicelo ezinjalo, i-Dacromet, i-zinc-nickel plating, okanye insimbi engenasici kufuneka ithathelwe ingqalelo.

3. Intloko yeCylindrical ene-Hex Socket Drive

3.1 Isishwankathelo soyilo

Intloko ye-cylindrical (ehlala ibizwa ngokuba yi-socket head cap screw head okanye i-DIN 912 / ISO 4762 intloko) ibonisa imilo ye-cylindrical emcaba ene-hexagonal socket embindini. Idayamitha yentloko iqhelekile malunga namaxesha ayi-1.5 idayamitha yomsonto, kwaye ubude bentloko bumalunga ne-0.6 ukuya ku-1.0 amaxesha obubanzi be-shank, kuxhomekeke kubungakanani. Le geometry inikeza indawo enkulu yokuthwala phantsi kwentloko ngelixa igcina iphrofayili epheleleyo kunye neprofayili ephantsi.

3.2 Izinto eziluncedo kuyilo lweCylindrical Head

Amandla okubamba okuphezulu: Intloko ye-cylindrical inikezela indawo enkulu yokuthwala ingaphezulu kune-countersunk okanye iqhosha lokuyila iintloko, ukusabalalisa umthwalo we-clamping kwindawo ebanzi kunye nokunciphisa umngcipheko wokungeniswa komphezulu okanye umonakalo kwi-workpiece.

Umzobo obambeneyo: Ngenxa yokuba intloko ihleli phezu komhlaba kunokuba i-countsunk, intloko ye-cylindrical ifuna kuphela umngxuma olula okanye umngxuma ocofelweyo. Akukho msebenzi wokubala ofunekayo, ukwenza lula ukwenziwa.

Ufakelo olugungxulwayo okanye olunyusiweyo: Intloko ingafakelwa ugungxulo kunye nomphezulu (ukuba isicelo sivumela intloko ephakanyisiweyo) okanye iphinde ihlawulwe kwi-counterbore ukuze igqibezele ukugungxulwa ngokupheleleyo, inikezela ngobubhetyebhetye boyilo.

Inkangeleko ecocekileyo: Intloko egudileyo yesilinda ibonisa ukucoceka, inkangeleko efanayo ekhethwa ngobuhle koomatshini, izixhobo zokusebenza, kunye ne-elektroniki yabathengi.

3.3 IiNzuzo ze-Hex Socket Drive

I-hexagonal socket (Allen) idrayivu lujongano oluchazayo lwesokhethi yentloko yesikrufu. Isitshixo se-Allen hex (isikrufu) sifaka ikhefu elinamanqaku amathandathu, lithumela itorque ukuqhuba isikrufu. Le nkqubo yokuqhuba ibonelela ngeengenelo ezininzi ezahlukileyo ngaphezulu kwe-hex yangaphandle, iPhillips, okanye iidrive ezifakiweyo:

Ukuhanjiswa kwetorque ephezulu: I-hex socket yangaphakathi inokumelana ne-torque ephezulu kakhulu kunePhillips okanye i-slotted drives, eyenza ukuqiniswa okuthembekileyo kumaxabiso aphezulu okulayisha kwangaphambili afunekayo kwii-Fasteners zeBanga lesi-8.8 (ukuya kuthi ga kwi-80% yomthwalo wobungqina kumalungu abalulekileyo).

Ukuchaswa kweCam-out: Ngokungafaniyo ne-Phillips drives eyenzelwe ukukhupha (ukukhupha) phantsi kwe-torque ephezulu, i-hex socket igcina ukubandakanyeka okupheleleyo, ukunciphisa umngcipheko wesixhobo kunye nomonakalo wentloko.

Ukufikelela kwiprofayili ephantsi: Isitshixo se-hex sisondela ukusuka phezulu (ulwalathiso lwe-axial), ukuvumela ukufakwa kwiindawo ezivaliweyo apho i-wrench ayikwazi ukufikelela ukusuka kwicala. Oku kubaluleke ngakumbi kwiindibano zoomatshini abaxineneyo.

Ukunciphisa umngcipheko wokuqhawula: Indawo enkulu yoqhagamshelwano phakathi kwesitshixo se-hex kunye neendonga ze-socket ihambisa uxinzelelo ngokulinganayo, ukunciphisa ithuba lokuguqulwa kodonga lwesokhethi okanye ukuhluthwa, nasemva kokufakwa ngokuphindaphindiweyo kunye nemijikelezo yokususa.

4. Usetyenziso oluqhelekileyo

IBanga le-8.8 le-hex socket head cap izikrufu ezimnyama zisetyenziswa kuluhlu olubanzi lwamashishini apho amandla aphakathi aphezulu, ukhuseleko lomhlwa lwangaphakathi, kunye nokufikelela kwindibano ehlangeneyo kufuneka:

Ukwenziwa koomatshini kunye nezixhobo: Ukunyuswa kwe-injini, izindlu zeebhokisi zegiya, iindibano zempompo, kunye noqhagamshelo lwesakhelo solwakhiwo.

Izemoto (zangaphakathi nezingavezwanga): Iindibano zedeshibhodi, iifreyimu zezihlalo, izibiyeli zetrim zangaphakathi, kunye nezixhobo ezingaphantsi kwe-hood ezikhuselweyo ekuchaselweni ngqo kwimozulu.

Izixhobo kunye nokulungiswa: Iziseko zomngundo, ijig kunye ne-fixture assemblies, kunye neeseti zokufa apho ukubethelwa okuchanekileyo kunye nokuphindaphinda ukuchithwa kuqhelekileyo.

I-Electronics kunye ne-enclosures: Izixhobo ezifakwe kwi-rack, iibhokisi ze-junction zombane, kunye neepaneli zokulawula apho ukugqiba umnyama ococekileyo kunye nentloko ephantsi ikhethwayo.

Ifenitshala kunye nezixhobo zoyilo: Izixhobo zefanitshala eziziimodyuli, iindawo zemiboniso, kunye nokufakelwa kwezakhiwo zangaphakathi.

5. Isiphelo

IBanga le-8.8 le-oxide ye-hex ye-socket ye-socket ye-screws yentloko imele isisombululo esilungelelene kakuhle esijongene neemfuno zobunjineli ezimbini ezibalulekileyo ngaxeshanye. Ukugqitywa kweoksidi emnyama kubonelela ngomqobo ocekeceke, ozinzileyo, one-hydrogen-embrittlement-free corrosion barrier eyongayo kwaye ingaguquguquki ngokubonakalayo. Ngelixa ukuxhathisa kwe-corrosion kulinganiselwe xa kuthelekiswa neengubo zeprayimari ezifana ne-Dacromet okanye i-zinc-nickel, ingaphezu kokwaneleyo kwiindawo ezingaphakathi kunye nezonakalise kancinci. Intloko ye-cylindrical ene-hex socket drive, okwangoku, ihambisa ukuhanjiswa kwe-torque ephezulu, amandla okufakela i-compact, kunye ne-aesthetic ecocekileyo eyenza kube lukhetho olukhethiweyo kwiindibano zoomatshini apho indawo, ukuthembeka, kunye nenkangeleko yonke ibalulekile. Ngokudibeneyo, ezi mpawu zimbini zenza iBanga lesi-8.8 lentloko yesokhethi emnyama ye-oxide isikrufu esisebenza ngeendlela ezininzi, esineendleko ezifanelekileyo, kunye nesibophelelo esinokuxhomekeka kuluhlu olubanzi losetyenziso lwemizi-mveliso.
