I-Dacromet Hexagonal Bolts | Isishwankathelo soBugcisa 

1. Intshayelelo

Iibholiti ezine-hexagonal, ezaziwa ngokuba zii-hex bolts, ziphakathi kwezona zibophelelo zisetyenziswa kakhulu kubunjineli nolwakhiwo. Xa ziphuculwe ngetekhnoloji yokwambatha ye-Dacromet, ezi bholiti zihambisa uxhathiso olukhethekileyo, ukuthembeka koomatshini, kunye nokuthembeka kwexesha elide nakwiindawo ezibuhlungu kakhulu. Eli nqaku linika inkcazo ecacileyo ye-Dacromet ye-hexagonal bolts, ehlanganisa ukubunjwa kwabo, inzuzo, inkqubo yokuvelisa, iinkcukacha zobugcisa, kunye nezicelo zoshishino.

I-Dacromet yinkqubo yokugquma i-zinc-flake eyi-proprietary eyenzelwe ushishino lweemoto. Iqukethe i-zinc kunye ne-aluminium flakes edityaniswe yi-inorganic chromate matrix. Ngokungafaniyo ne-electroplating yendabuko okanye i-hot-dip galvanizing, inkqubo ye-Dacromet ayikho i-electrolytic, ebangela ukuba umaleko obhityileyo kodwa osebenzayo okhuselayo ongabangeli i-hydrogen embrittlement-inzuzo ebalulekileyo kwi-fasteners ephezulu.

Yintoni iDacromet Coating?

I-Dacromet (ekwabizwa ngokuba yi-zinc-flake coating) isiseko samanzi, i-inorganic coating eyenziwe kwi-zinc powder, i-aluminium powder, kunye ne-chromate binders. Isetyenziswe nge-dip-spin okanye inkqubo yokutshiza elandelwa yi-high-temperature yokunyanga (malunga ne-300 ° C), i-coating yenza i-multi-layered barrier enikezela ukukhuselwa kwe-cathodic, ukukhuselwa komqobo, kunye neempawu zokuziphilisa.

Ubungqingqwa befilimu eyomileyo busuka kwi-4 ukuya kwi-12 ye-micrometer, buncinci kakhulu kune-galvanizing ye-hot-dip eqhelekileyo (50-80 μm). Nangona iprofayili yayo encinci, i-Dacromet-coated surfaces ihlala imelana ngaphezu kweeyure ze-1,000 zokuvavanya ityuwa-spray engathathi hlangothi ngaphandle kokubonakala komhlwa obomvu.

2. Izinto eziluncedo eziphambili zeDacromet Hex Bolts

Iibholiti ze-Dacromet ezinehexagonal zibonelela ngokudityaniswa okukhethekileyo kweepropathi ezidlula uninzi lwezonyango zemveli:

• Ukuxhathisa okuPhakamileyo kokuMnyama: Ukusebenza kwesitshizi setyuwa kudlula iiyure eziyi-1,000–1,200 (ISO 9227 / ASTM B117), malunga namaxesha ayi-7–10 angcono kunomgangatho wokugalela i-electro-galvanizing.
• Akukho Ukuhonjiswa kweHydrojeni: Inkqubo ye-non-electrolytic iphelisa ukuxutywa kwe-hydrogen, okwenza i-Dacromet ibe yinto efanelekileyo kwiibholithi eziphezulu (iBakala 8.8, 10.9, 12.9 kunye ne-ASTM A490).
• Uzinzo lobushushu obuphezulu: Ukushisa kwenkonzo eqhubekayo ukuya kwi-300 ° C ngaphandle kokuthotywa kwefilimu ekhuselayo-iphezulu kakhulu kwiingubo eziqhelekileyo ze-zinc.
• Okugqwesileyo komtya kunye nokuzinza koMda: I-Thin coating igcina i-thread geometry kwaye ivumela indibano egudileyo ngamandongomane asemgangathweni.
• Ukupeyinta okuLungileyo kunye nokuSebenza kwakhona: Ukunamathela olomeleleyo kwiidyasi ze-organic zenza ukuba ubuhle obungakumbi okanye ukugqiba ukusebenza.
• Ukuhambelana kweBimetallic: Yenza kakuhle xa udibana ne-aluminiyam kunye nezinye iintsimbi ezingafaniyo, ukunciphisa umngcipheko wokubola kwegalvanic.

3. Inkqubo yokuVelisa

Inkqubo yokugquma i-Dacromet yeebholiti ze-hexagonal lulandelelwano olulawulwa ngononophelo oluqinisekisa ukugubungela okufanayo kunye nokusebenza okuphezulu:

1. Ukulungiswa komphezulu: Iibholiti zicocwa ngokucokisekileyo kwaye zicocwe ukuze kususwe i-oyile, i-oxides, kunye nezingcolisi. Akukho kucholwa kweasidi efunekayo, ngakumbi ukunciphisa umngcipheko we-hydrogen.
2. Isicelo seDip-Spin: Amalungu antywiliselwa kwi-aqueous Dacromet suspension aze ajikelezwe ngesantya esilawulwayo ukufezekisa ubukhulu befilimu efanayo kunye nokususa ukugquma okungaphezulu.
3. Ukunyanga kwangaphambili kunye noNyango lokugqibela: Ubushushu obuphantsi bokubhaka kwangaphambili buba ngumphunga amanzi, kulandelwa yi-sintering yobushushu obuphezulu (~300°C) edibanisa iiflakes ze-zinc-aluminiyam zibe yityabeka exineneyo, ebambelelayo.
4. Ukuhlolwa koMgangatho: Ubukhulu bokwambathisa, ukuncamathela (uvavanyo lokunqunyulwa komnqamlezo), inkangeleko, kunye nesampulu yokutshiza ityuwa ziyenziwa ukuqinisekisa ukuguquguquka kwebhetshi.

4. IiNgcaciso zobuGcisa kunye neMigangatho

Iibholiti ze-Dacromet ze-hexagonal zenziwa kuluhlu olubanzi lwemigangatho yamazwe ngamazwe kwaye zifumaneka kwiiklasi zepropathi ezininzi.

5. Izicelo zoShishino

Enkosi kwindibaniselwano ebalaseleyo yamandla kunye nokumelana nomhlwa, iibholiti ze-Dacromet zehexagonal zicacisiwe kumacandelo amaninzi afunayo:

6. Isiphelo

Iibholiti ze-Dacromet ze-hexagonal zimela isisombululo esivuthiweyo, esiphezulu sokusebenza esidibanisa i-gap phakathi kwee-coatings ze-zinc eziqhelekileyo kunye neendlela ezibiza kakhulu ezifana ne-stainless steel okanye iinkqubo ezikhethekileyo ze-alloy. Ubugcisa bazo obunefilimu ecekethekileyo bukhusela umhlwa ngendlela ebalaseleyo, buphelisa ukuxhalaba kwehydrogen, bugcina imilinganiselo ethe ngqo, yaye bumelana namaqondo obushushu aphakamileyo—iimpawu ezibangela ukuba zibe yimfuneko kubunjineli bale mihla.

Njengoko amashishini aqhubeka efuna ubomi obude benkonzo, ukugcinwa okuncitshisiweyo, kunye nokuthembeka okuphezulu phantsi kweemeko zendalo ezinobundlobongela, ukwamkelwa kweefasteners ezifakwe kwi-Dacromet kulindeleke ukuba kwandiswe ngakumbi. Ngokukhetha ibakala elifanelekileyo, ubungakanani, kunye nengcaciso yokwambatha, abayili kunye neengcali zokuthenga banokufikelela zombini ukugqwesa kobugcisa kunye nokusebenza okunexabiso eliphantsi.

Kwiingcebiso ezikhethekileyo zeprojekthi okanye amaphepha edatha yobugcisa, qhagamshelana nabanikezeli be-fastener abaqeqeshiweyo kunye neengcali zokwaleka.
