Inkqubo yokulungiswa komphezulu we-Fastener: i-galvanizing, i-phosphating, i-blackening, yintoni endimele ndiyikhethe?

Kwishishini lanamhlanje, i-fasteners zizinto eziphambili zokudibanisa iinxalenye, kwaye ukusebenza kwazo kuchaphazela ngokuthe ngqo ukuzinza kunye nokhuseleko lwezixhobo zonke. Ukunyangwa komphezulu we-fasteners akuhambelani kuphela nokubonakala kwabo okuhle, kodwa kunye nokusebenza kwabo okuchasene ne-corrosion kunye nobomi benkonzo. Ngoko ke, ukukhetha inkqubo efanelekileyo yonyango yomhlaba ibe yinxalenye ebalulekileyo yokwenziwa kwe-fastener engenakunakwa.

Okokuqala, makhe sithethe nge-electrogalvanizing esetyenziswa kakhulu. KUNYEi-lectrogalvanizing iye yaba sisigqubuthelo esiqhelekileyo sezinto zokuqhobosha ezithengiswayo ezinexabiso eliphantsi kunye nenkangeleko entle. Nangona kunjalo, ukusebenza kwayo kwe-anti-corrosion ayivelele, ngakumbi kwindawo yokufuma ephezulu okanye kwiindawo ezidliwayo, kwaye ukuqina kwayo kufuneka kuphuculwe. Ukuze kulungiswe le ngxaki, ezinye izitywini ezikhethekileyo ziye zaziswa ukwandisa ubomi bayo bokuchasana nokubola. Kodwa iindleko zonyango olunjalo nazo zonyukile, kwaye kufuneka zilinganiswe ngokwemeko ethile yokusetyenziswa.

Okulandelayo nguiphosphating. I-Phosphating ayinakufikeleleka kuphela, kodwa inokumelana nokugqwala okulungileyo kunye nokumelana nokugqoka, ngokukodwa ifanelekileyo kwiibholiti eziphezulu. I-oiling emva kwe-phosphating inokuphucula ngakumbi ukusebenza kwayo kwe-anti-corrosion kwaye ifanelekile ukudityaniswa kweendawo ezibalulekileyo. Kuyafaneleka ukukhankanya ukuba i-phosphating inokuphepha ngokufanelekileyo i-hydrogen embrittlement, eyona nto kufuneka ithathelwe ingqalelo ekwenzeni iibholiti eziphezulu.

Makhe sithethe ngayoi-oxidation (imnyama)unyango. Le ndlela yonyango inexabiso eliphantsi kakhulu, kodwa iya kugqwala ngokukhawuleza ngokungabikho kweoli. Ngoko ke, ngokuqhelekileyo kudibaniswa ne-oiling ukwandisa ubomi benkonzo. Nangona ukuxhathisa umhlwa kunqongophele, iselukhetho lwezoqoqosho kwiimeko ezithile ezingakhathaliyo.

I-Cadmium electroplatingiqhuba kakuhle kwimo engqongileyo yaselwandle ngenxa yokumelana nokugqwesa kwayo okugqwesileyo. Nangona kunjalo, iindleko eziphezulu kunye neendleko zokunyanga ulwelo lwenkunkuma ngexesha lenkqubo yokucubungula zinciphisa uluhlu lwesicelo. I-Chromium electroplating yaziwa ngobulukhuni bayo obuphezulu kunye nokumelana nokunxiba, kodwa ineendleko eziphezulu kunye neengxaki ze-hydrogen embrittlement.

I-Nickel platingyindlela yonyango engaphezulu enokuthintela ukubola kunye nokugcina i-conductivity elungileyo. Isetyenziswa ikakhulu kwiimeko apho zombini ukuxhathisa umhlwa kunye ne-conductivity kufuneka, njengeetheminali ezikhokelayo zeebhetri zesithuthi.

I-Hot-dip galvanizing kunye nokungena kweZinczimbini iindlela zonyango lomphezulu ezisetyenziswa kakhulu kubunjineli. I-Hot-dip galvanizing iyaziwa ngokutyabeka kwayo okungqindilili kunye nokumelana nokugqwesa okuhle, kodwa kunokubangela iingxaki ngobunzima bokukrola imisonto yangaphakathi nangaphandle. Ukungeniswa kwe-zinc kuyathandwa ngenxa yokufana kwayo okulungileyo, amandla okubambisana okuphezulu kunye ne-substrate, kunye nokukhuselwa kwendalo kunye nokungangcoli.

Ekugqibeleni, kufuneka sikhankanyeDacrometunyango. Olu didi lutsha lwe-anti-corrosion coating alunamsebenzi obalaseleyo wokuchasana nokubola, kodwa alunayo ingxaki ye-hydrogen embrittlement kunye ne-torque-preload consistency. Nangona kunjalo, iyabiza kwaye ineengxaki zokusingqongileyo, ngoko ke kufuneka isetyenziswe emva kokuqwalaselwa ngokubanzi kweendleko kunye neemfuno zokusingqongileyo.

Isishwankathelo, ukhetho lonyango lomphezulu we-fastener kufuneka luqwalasele ngokubanzi izinto ezininzi ezifana nokusebenza kokuchasana nokubola, iindleko, indawo yokusetyenziswa, iimfuno zokusingqongileyo, kunye neemfuno zokusebenza kwe-fastener ngokwayo. Kuphela ngokufumana eyona ndlela ifanelekileyo yonyango lomhlaba sinokuqinisekisa ukuba i-fastener igcina ukusebenza okuzinzile kunye nokhuseleko oluthembekileyo ekusebenziseni ixesha elide.
