Imizobo engundoqo yeHardware eyiGalvanized

I-Hydrogen Embrittlement Risk

Kufuneka wazi malungai-hydrogen embrittlementngaphambi kokukhetha izikrufu ezifakwe igalvanized and nuts. Le ngxaki yenzeka xa ihydrogen ingena esinyithini ize iyenze inkukuma. I-brittle metal inokuqhekeka okanye iphuke phantsi koxinzelelo.

Izinto ezininzi zonyusa umngcipheko we-hydrogen embrittlement:

• Ukonakala, ngakumbi kwiindawo ezineasidi okanye ezinetyuwa, kuvelisa ihydrogen kumphezulu wesinyithi.
• Ukufuma kudlala indima enkulu, ngakumbi kwiindawo ezinomswakama ophezulu.
• Ukubonakaliswa ngexesha lokwakha, njengokusebenza kwiimeko ezimanzi, kunokukhawulezisa ukungena kwe-hydrogen.
• Iimeko zenkonzo ezinamaqondo angaqinisekanga okanye aphezulu okufuma ziphakamisa umngcipheko.

Ujongene nomngcipheko ophezulu xa ezi zinto zintathu zisenzeka kunye:

1. I-Hydrogen ikhona.
2. I-fastener iphantsi komthwalo oqhubekayo okanye uxinzelelo.
3. Izinto eziphathekayo zichaphazeleka, ngakumbi intsimbi ephezulu.

Uxinzelelo olungenanjongo ngexesha lofakelo lunokulayisha ngaphezulu izikrufu kwaye zenze ukuba i-embrittlement ibe lula. Kufuneka uhlale ulawula imithombo yoxinzelelo kwaye ugweme ukuqinisa ngokugqithiseleyo izibophelelo.

Ingcebiso:Ukuba usebenzisa iziqhoboshi ezifakwe igalvanized kwiindawo ezimanzi okanye ezonakalisayo, jonga iimpawu zokuqhekeka okanye ukulahleka kwamandla ngokuhamba kwexesha.

Imiba yokuFaka kwiZinc yoKutyabeka ukutyeba

Izikrufu zegalvanized kunye namandongomane anezinc ejiyileyo yokwaleka. Olu gquba lukhusela umhlwa, kodwa lunokubangela iingxaki xa uzama ukubophelela amalungu ndawonye. Ubukhulu be-zinc layer bunokwenza izikrufu kunye namandongomane zibe nzima ukungena kwimingxuma okanye imisonto.

Imigangatho yeshishini ibeka imida yokutyeba kwe-zinc yokwambathisa ukunqanda iingxaki zokuqina. I-Zinc plating idla ngokunika umaleko omncinci, ocwebezelayo, olungele iziqhoboshi ezincinci kwiimeko ezithambileyo. I-Hot-dip galvanizing idala umaleko otyebileyo, osebenza ngcono kwiindawo ezirhabaxa kodwa unokwenza ukuba kubenzima ngakumbi.

• I-Commercial zinc plating inobunzima obuncinci be-0.00015 intshi.
• Idiphu eshushu ye-galvanizing inika i-coat ejiyileyo neyomelele ngakumbi, malunga ne-1.0 mm ubukhulu.
• Izibophelelo ezifakwe kwi-zinc zisebenza kakuhle kwindawo epholileyo, kodwa izibophelelo ezifakwe emanzini ashushu zingcono kwiimeko ezinzima.

Ayilunganga kusetyenziso loxinzelelo oluphezulu

Izikrufu zegalvanized kunye namantongomane azisebenzi kakuhle kwi-high-stress-stress okanye kwi-application-bearing loading. Unokubona iingxaki ezifana nokuqhekeka okanye ukusilela ngequbuliso ukuba uyazisebenzisa apho kukho amandla anamandla.

Umngcipheko we-hydrogen embrittlement uphezulu kwi-fasteners enamandla e-tensile ngaphezu kwe-150 ksi. Lo mbandela ubangela ukuba isinyithi silahlekelwe yi-ductility kwaye siphuke kwangoko. Imigangatho yeshishini, efana ne-ASTM A143 kunye ne-ASTM F2329, ilumkisa ngokuchasene nokusebenzisa iziqhoboshi ezishushu zediphu kwimisebenzi ephezulu yamandla.

Kwiindawo ezinoxinzelelo oluphezulu, iibholiti zegalvanized zinokubandezeleka ngenxa yoxinzelelo lwe-corrosion cracking kunye ne-hydrogen-induced cracking. Amandla abo anokwehla ngaphezulu kwe-20% emva kokusetyenziswa kwexesha elide. Umxholo we-hydrogen kwezi bholithi unokunyuka ngaphezu kwe-300%, ubenze ukuba bangaphumeleli. Iibholiti ezigqunywe ngamandla aphezulu zigcina iimpawu zabo zomatshini zingcono phantsi koxinzelelo.

Phawula:Iibhulorho, oomatshini abanzima, okanye izixhaso zolwakhiwo, kuya kufuneka ukhethe iziqhoboshi ezenziwe ngemathiriyeli eyomelele kakhulu njengentsimbi engatyiwa okanye yentsimbi.

Iinkxalabo zokuhambelana nezinye izinto

Kufuneka uqwalasele ukuhambelana xa usebenzisa izikrufu zegalvanized kunye namandongomane kunye nezinye izinto zokwakha. Ezinye iindibaniselwano zinokubangela umhlwa okanye ukusabela kweekhemikhali ezenza buthathaka iprojekthi yakho.

Imithombo emininzi ezimeleyo ilumkise ukuba umhlwa omhlophe kunye nobomvu wenza ngokukhawuleza xa iziqhoboshi ezishushu eziditshiweyo zivavanywa ngomthi onyangiweyo ongeyo-arsenate. Ngokutsho kwengxelo ye-EPA, '[t]apha kuye kwakho uvavanyo olulodwa olukhawulezayo lweminyaka oluqhutywe lishishini lokwakha olubonisa ukuba kunye ne-hardware ebhengeza ukuchasana okuphuculweyo kwi-corrosion iqala ukubonisa iimpawu zokugqwala ngaphakathi kweeyure ze-1000 zovavanyo olukhawulezayo lweminyaka yobudala (elilingana neminyaka eyi-16 yokuvezwa okufakiwe) xa isetyenziswe ngamaplanga aphethwe yi-ACQ.'

• Amaplanga anyangelwe ngokugcinwayo anokungahambelani nezikrufu ezinezikrufu kunye ne-aluminiyam.
• Iziqhoboshi zentsimbi okanye izikhonkwane zediphu ezishushu ezenziwe kwi-ASTM A153 Udidi D okanye umsebenzi onzima kakhulu ngamaplanga acoliweyo.
• Xa udibanisa iipaneli zetsimbi kwimithi ephathwayo, ungasebenzisa umqobo wokufuma phakathi kwamaplanga kunye nepaneli.
• Iziqhoboshi ezingahambelaniyo ziquka izikrufu ezine-zinc plated, izikrufu ezinentloko ye-zinc-alloy, kunye nezikrufu ezine-capped stainless.

Ukuchaphazeleka kweekhemikhali kunokuthi kwenzeke phakathi kokwalekwa kwegalati kunye nekhonkrithi, ngakumbi ngexesha lokunyanga. Le nkqubo ikhupha irhasi yehidrojeni kwaye yenza buthathaka iqhina phakathi kwerebar eyenziwe ngegalvanized kunye nekhonkrithi. Unyango lweChromate lunceda ukunciphisa ezi ngxaki.

Isilumkiso:Ngalo lonke ixesha ujonge ukuhambelana kweziqhoboshi zakho kunye nemathiriyeli kwiprojekthi yakho. Ukusebenzisa indibaniselwano engalunganga kunokukhokelela ekugqweseni kwangaphambili, amalungu abuthathaka, okanye ukusilela kwesakhiwo.

Ukusetyenziswa nini Izikrufu zeGalvanized and Nuts

IiProjekthi ezigqwesileyo zezicelo

Ufumana elona xabiso liphezuluizikrufu zegalvanized kunye namandongomanekwiiprojekthi ezijongene nemozulu, ukufuma, okanye ukuba sesichengeni sangaphandle. Iingcali zeshishini zicebisa ezi zibophelelo kusetyenziso olungundoqo oluninzi:

1. Iiprojekthi zangaphandle: Ungasebenzisa izikrufu ezenziwe ngamabibi eecingo, iidekhi, kunye nefenitshala yangaphandle. Ukunganyangeki kwabo kumhlwa kugcina umsebenzi wakho womelele nasemvuleni okanye elangeni.
2. IiProjekthi zoKwakha: Abakhi bahlala bekhetha iziqhoboshi zegalvanized zezakhelo zesakhiwo kunye nokwakhiwa ngokubanzi. Uzuza ngokuhlala kwabo kunye neendleko eziphantsi.
3. Umsebenzi womthi kunye neDecking: Izikrufu zegalvanized zisebenza kakuhle ngamaplanga acoliweyo. Banceda ukuthintela amabala kunye nomonakalo womthi ngokuhamba kwexesha.
