Intshayelelo kwi-Dacromet Flange Bolts-High-Performance Fasteners kwiiNdawo eziBangayo 

2. Ukuqonda iiBolts zeFlange

Ibhawudi yeflange sisiqhoboshelo esikhethekileyo esibonisa iflange ebanzi, esetyhula ebekwe ngokuthe ngqo phantsi kwentloko yebhawudi. Le flange isebenza ngokufanayo newasha eyakhelwe-ngaphakathi, isasaza umthwalo obambezelayo kwindawo enkulu. Ngokunyusa umgangatho wokuthwala, iibholiti ze-flange zinciphisa umngcipheko wokulimala komhlaba kwizinto ezidibeneyo kunye nokunceda ukukhusela intloko ye-bolt ekutsaleni ngezinto ezincinci okanye ezithambileyo.

Iimpawu eziphambili zoyilo lweebholithi zeflange ziquka:

I-flange edibeneyo: Iphelisa imfuneko yewasha eyahlukileyo kwizicelo ezininzi, ukwenza lula ukudibanisa kunye nokunciphisa inani leenxalenye.

Ukuhanjiswa komthwalo okuphuculweyo: Indawo enkulu yoqhagamshelwano ithoba uxinzelelo lwendawo kwindawo yokukhwelana.

Ukhetho olulungelelanisiweyo: Iibholiti ezininzi ze-flange zibandakanya ii-serration (amazinyo) ngaphantsi kwe-flange, ezigrumba phezulu ukuze zibonelele ukuxhathisa ukukhulula okubangelwa yi-vibration.

Izitayile zentloko eziqhelekileyo: Iibholiti ze-hexagonal ze-flange zentloko zezona zisetyenziswa kakhulu, zivumela i-wrench eqhelekileyo okanye ukufakwa kwe-socket.

Iibholiti ze-Flange zenziwe ngamabakala ahlukeneyo amandla (njengeBanga le-8.8, i-10.9, kunye ne-12.9 kwiinkqubo ze-metric) kunye nezixhobo, ezivela kwi-carbon steel kunye ne-alloy steel steel stainless steel. Ukuguquguquka kwabo kubenza bafanelekele iiprojekthi zeemoto, zokwakha, oomatshini kunye neziseko zophuhliso.

3. ITekhnoloji yoKugquma iDacromet

I-Dacromet (ekwaziwa ngokuba yi-DACROMET®) yinkqubo yokwaleka ye-zinc-aluminiyam engeyoye-electrolytic eyaphuhliswa ekuqaleni njengenye indlela yokusebenza ephezulu kwi-electroplating yendabuko kunye ne-hot-dip galvanizing. Ukwaleka kubandakanya i-zinc ethe kratya kunye neeflakes ze-aluminiyam ezisasazwe kwisibophelelo se-inorganic, esinezikhompawundi zechromium. Isetyenziswa njengodaka olusekwe emanzini ngokusebenzisa idiphu-spin, isitshizi, okanye iindlela zedip-drain, zilandelwa kukunyanga (ukubhaka) kumaqondo obushushu aphakamileyo amalunga nama-300°C.

Ngexesha lenkqubo yokunyanga, i-coating yenza ifilimu eshinyeneyo, ene-multi-layered inorganic edibanisa iikhemikhali kwi-substrate yensimbi. Ubungqingqwa obuqhelekileyo busuka kwi-5 ukuya kwi-12 ye-micrometers (μm), ebhityileyo kakhulu kunomaleko wokuntywila obushushu ngelixa ibonelela ngokhuseleko oluphezulu. Umphezulu osisiphumo unembonakalo eyahlukileyo yentsimbi esiliva-ngwevu.

Iindlela zokukhusela ezingundoqo zeDacromet ziquka:

Ukhuseleko lomqobo: Ulwakhiwo oluxineneyo, oluthe kratya lweflake ludala umqobo womzimba othintela ukungena kokufuma, iityuwa, kunye neearhente ezitshabalalisayo.

Ukhuseleko lwedini (cathodic): Iiflakes zeZinc zikhetha ukubola, zikhusela i-substrate yentsimbi engaphantsi.

Ukunyusa: Iikhompawundi zeChromium ezikwi-binder zinceda ukwenza umaleko ozinzileyo wokwenziwa kokwenziwa okwandisa ngakumbi ukuxhathisa umhlwa.

4. Izinto eziluncedo zeDacromet Flange Bolts

Ukudityaniswa koyilo olujijekileyo kunye nokwaleka kweDacromet kuzisa uluhlu lweenzuzo zokusebenza ezenza ezi zibophelelo zixabiseke ngakumbi kwizicelo ezifunwayo:

1.Ukumelana noKutya okuKhethekileyo: Iingubo ze-Dacromet zihlala zifezekisa ngaphezu kweeyure ze-1,000 zokunganyangeki kwetyuwa yokutshiza ityuwa (ASTM B117 / ISO 9227) ngaphandle kokubonakala kwe-rust ebomvu. Kwiimeko ezininzi, ukusebenza kufikelela kwiiyure ezingama-1,200–2,000 okanye ngaphezulu. Oku kuqhelekile ka-7 ukuya kwali-10 ukhuseleko olunikezelwa yi-electro-galvanizing eqhelekileyo.

2.Akukho kuMhlobiso weHydrojeni: Ngokungafaniyo neenkqubo ze-electroplating ezibandakanya ukucholwa kwe-asidi kunye nokubekwa kwe-electrolytic, isicelo se-Dacromet awazisi i-hydrogen kwintsimbi. Oku kwenza kube yinto efanelekileyo kwi-fasteners ephezulu (amaBanga 10.9, 12.9, kunye ne-ASTM A490), apho i-hydrogen embrittlement ingabangela ukulibaziseka ukuphuka kwe-brittle.

3.Ukumelana noBuqondo obuPhezulu: Ukwaleka kuhlala kuzinzile kwaye kukhuselwe kubushushu benkonzo eqhubekayo ukuya kutsho malunga ne-300 ° C (572 ° F), igqithise kakhulu imilinganiselo yobushushu beyona nto ininzi ye-zinc electroplated.

4.Thin, iUniform Coating: Ngobunzima obuqhelekileyo be-5-12 μm kuphela, isambatho sinempembelelo encinci kwimilinganiselo yentambo kunye nokufaneleka. Amandongomane asemgangathweni anokuthi asetyenziswe ngaphandle kokucofa kwakhona okanye uhlengahlengiso, ngokungafaniyo neengubo ezityebileyo zediphu.

5.Ukumelana kakuhle noomatshini kunye neekhemikhali: I-coating ibonisa ukubambelela okuqinileyo, ukuchasana nomonakalo omncinci womatshini ngexesha lokuphatha kunye nokufakwa, kunye nokuhambelana neekhemikhali ezininzi, i-oyile kunye ne-solvents.

6.Iimpawu zeFriction eLawulwayo: Ngeengubo eziphezulu ezifanelekileyo okanye i-lubricant, i-coefficient of friction inokwenziwa ngobunjineli obuhambelanayo be-torque-tension, ukuphucula ukuthembeka ngokubambisana.

7.IiNzuzo zokusiNgqongileyo kunye neNkqubo: Njengenkqubo engeyiyo eye-electrolytic, esekwe emanzini, i-Dacromet ivelisa inkunkuma enobungozi obuncinci kune-plating yendabuko kwaye ithathwa ngokubanzi njengokhetho olunoxanduva lokusingqongileyo (nangona imixube emidala iqulethe i-chromium enehexavalent; ukwahluka kwale mihla kunye neendlela ezizezinye ziyaqhubeka nokuvela kwimpembelelo ephantsi yokusingqongileyo).

5. Uthelekiso lweNtsebenzo

Le theyibhile ilandelayo ishwankathela iimpawu zokusebenza eziqhelekileyo zokwaleka kweDacromet xa kuthelekiswa nesiqhelo se-zinc plating kunye ne-hot-dip galvanizing:

Qaphela: Ukusebenza okwenene kuyahluka ngokwebakala lokutyabeka, ubukhulu, idyasi, ukulungiswa kwesubstrate, kunye neemeko ezithile zovavanyo. Idatha imele iziphumo zemveliso eziqhelekileyo.

6. Ukuqukumbela

I-Dacromet flange bolts imele isisombululo esiphezulu sokusebenza esidibanisa ngempumelelo izibonelelo zoyilo lomatshini kunye neteknoloji yokukhusela i-corrosion. I-flange edibeneyo iphucula ukuhanjiswa komthwalo kwaye inokunciphisa imfuno yokuhlamba okuhlukeneyo, ngelixa i-Dacromet ye-zinc-aluminium flake enqabileyo kodwa esebenzayo kakhulu inika ukuchasana okubalaseleyo kwi-spray yetyuwa, umswakama, iikhemikhali, kunye nokushisa okuphakamileyo-ngaphandle kweengozi ze-hydrogen embrittlement ezinxulumene ne-electroplating yendabuko.

Ezi mpawu zenza i-Dacromet flange bolts ifaneleke ngokukodwa kwiimoto, amandla avuselelekayo, ukwakhiwa, ezolimo, elwandle, kunye nezicelo zoshishino apho ubomi benkonzo ende kunye nokuthembeka phantsi kweemeko ezinzima kubalulekile. Njengoko imimiselo yokusingqongileyo kunye nokulindela ukusebenza kuqhubeka nokunyuka, ukusetyenziswa kwe-non-electrolytic zinc flake coatings ezifana ne-Dacromet kulindeleke ukuba kuhlale kuyindlela ebalulekileyo yeenjineli ezichaza i-fasteners ebalulekileyo.

Xa ukhetha iibholiti ze-Dacromet flange, ingqwalasela ngokucophelela kwibakala lomatshini, ukucaciswa kwengubo, imigangatho ye-dimensional, kunye neendlela zokufakela kuya kuqinisekisa ukusebenza kakuhle kunye nokuqina kwisicelo esijoliswe kuyo.
