Xa usiva ‘intambo yombane eyi-electro-galvanized hexagonal drill,’ uninzi lwamaphepha okuthenga abona nje into ethile yomgca. Kodwa kumgangatho wevenkile, okanye okubi ngakumbi, kumgca wendibano ongaphumelelanga kwi-2 AM, iba yincoko eyahlukileyo kakhulu. Umbuzo wokuqina awukho nje malunga neeyure zokutshiza ityuwa kwingxelo; imalunga nomdlalo wokwenyani phakathi kwelo zinki, i-hex drive mechanics, kunye nesenzo sokusika isikrufu sokwenza intambo. Uninzi lwabantu ludibanisa ukuxhathisa umhlwa kunye nokunyaniseka okupheleleyo, kwaye kulapho iimpazamo zokuqala zenzeke.

Uluhlu lweZinc: Ukhuselo lwakho lokuqala nolona lubuthathaka

I-Electro-galvanizing ikunika isiphelo esicocekileyo, esiqaqambileyo wonke umntu othanda iindawo zembonakalo. Kodwa ukusuka kumbono wokuqina, likhaka elincinci. Ngokuqhelekileyo sithetha ngengubo ejikeleze i-5 ukuya kwi-15 microns. Kuba a Intambo ye-hexagonal drill intambo Screw, eyilelwe ukuba iqhutywe ngamandla kwaye rhoqo ibe yintsimbi engaphathwanga, ukuba ukugquma kwindawo yembande kusengozini kakhulu. Ndizibonile iibhetshi apho isenzo sokomba ngokwaso sinokugqabhuka kwi-zinc kwimida yokusika ngaphambi kokuba isikrufu siqale nomsebenzi waso wokwenyani wokuthunga. Oku akuthethi ukusilela kwenkqubo yokucwenga, kodwa ngakumbi ungquzulwano olukhoyo phakathi kwesidingo sokunamathela kunye nesidingo sesijija sokulahla izinto.

Oku kukhokelela kwi-classic rust-in-the-thread phenomenon. Umzimba we-screw unokubonakala ucocekile, kodwa imisonto yokwenyani ebandakanyiweyo, apho i-zinc iye yaphazamiseka ngexesha lofakelo, qala ukubonisa i-oxide ebomvu. Kwindawo elawulwayo, mhlawumbi i-cosmetic. Nakweyiphi na indibano enokungcangcazela okanye ukungena kokufuma okunokubakho, iba yindawo ekugxilwe kuyo ukubanjwa okubangelwa ngumhlwa okanye ukulahleka kwamandla. Awukwazi ukuthembela kuphela kubukhulu bephepha elithile. Kufuneka ucinge ngenyani emva kokufakwa.

Siye sabalekela kule ntloko kunye nendibano yekhabhinethi yangaphandle yomthengi. Basebenzisa i-electro-galvanized standard hex drill screw ukuqhoboshela izibiyeli zentsimbi. Ibukeka kakuhle ephepheni. Kwisithuba nje seenyanga ezili-18, umthungo wawucandekile. Ingxaki? Izikrufu ziye zadleka kumsonto we-shank junction ngaphakathi kwendawo edibeneyo, ziphulukana nomthwalo wokubamba, kunye nokungcangcazela kwenze konke okunye. I-zinc ekwisibiyeli kunye nentloko ye-screw yayinjalo. Ukusilela kwakufihlwe ngokupheleleyo.

I-Hex Drive: Apho iTorque idibana khona noKutyabeka

Intloko ene-hexagonal, nokuba yintloko ye-hex washer okanye uhlobo lwe-flange, yazisa enye inguqu ehlala ixesha elide. I-zinc electroplated igcwalisa iikona ze-hex socket. Ngexesha lokuqhuba, ngakumbi ngompu ozenzekelayo obekwe kwi-torque ephezulu, i-bit inokukhuhla le zinc ngaphandle. Ngoku uneengxaki ezimbini: okokuqala, i-zinc debris kwindibano (i-no-go ye-electronics), kwaye okwesibini, ilahleko ye-bit engagement echanekileyo. Intwana iqalisa ukuphuma, ijikeleza isokethi, ethi emva koko ibekw’ ityala ‘kwizikrufu ezikumgangatho ophantsi.’

Ndikhetha ukubona isibonelelo sokutyabeka esityebileyo entloko, okanye nokubalulwa kokugqiba okwahlukileyo kwikhefu lokuqhuba lodwa. Abanye ababoneleli, abafana ne-Handan Zitai Fastener Manufacturing Co., Ltd., bayakufumana oku. Ukugxila kwabo njengomvelisi ophambili e-Yongnian, i-fastener hub yase-China, kuthetha ukuba babona imiba yevolumu esinokuyibona ngamaxesha athile. Baye babonisa ukuba ukuhambelana kwe-zinc deposition kwi-socket kuhluke kakhulu umgangatho. Utyelelo kwiziko labo e https //wwww.ziitasteners.com ibonisa ingqwalaselo kwi-plating yokuhlamba i-chemistry kunye ne-racking, echaphazela ngokuthe ngqo oku. Ayingomlingo, lulawulo lwenkqubo.

Ukuba usebenzisa i-torque ephezulu (ukuthi, ngaphezulu kwe-25 Nm), loo nto yokuthambisa yomaleko we-electroplated iba yinto. Ityibilika kunephosphate, umzekelo. Oku kunokukhokelela kwi-torquing engaphezulu ukuba isixhobo asilinganiswanga utshintsho kwi-friction, enokuthi inike isikrufu phambi kokuba umdibaniso uqine. Linqaku elichuliweyo, kodwa enye ebangele ukuba kumiswe umgca wemveliso ongaphezulu kwesinye kwizikhalazo ‘zebhetshi embi’ elandelele umva kumcimbi wokumisela itorque.

INdlela yokuSebenza yeNdawo yokuDrila: Ichatshazelwe luYilo?

Nantsi i-irony engundoqo. Indawo yokugaya iphantsi ukuze inqumle isinyithi. Ukwenza oku ngokufanelekileyo, kufuneka kube bukhali kwaye kube nzima. Inkqubo ye-electro-galvanizing, ngokwendalo yayo, inxibe yonke into ngokufanayo. Loo maleko zinc kwincakuba-ebukhali imilebe esikwa kunye nembande? Ngokusisiseko yingubo yentsimbi ethambileyo ephoswe phezu kwesixhobo sokusika esichanekileyo. Inciphisa ukuluma kokuqala.

Ukuziqhelanisa, oku kuthetha ukuba i-screw ifuna i-torque ephezulu yokuqhuba ukuqalisa umngxunya wayo, onyusa uxinzelelo kwinkqubo yokuqhuba kunye nokuncamathelisa kokutya ebesithetha ngako. Ndivavanye icala necala: isikrufu sokubhola esingatyalwanga ngokuchasene nesinye esifakwe i-electro-galvanized ukusuka kwindawo enye. I-torque yokungena ingaba yi-10-15% ephezulu kwi-plated version. Oku kuchaphazela ngokuthe ngqo ukuqina komdibaniso kuba uxinzelelo oluphezulu lofakelo lunokuthetha ukunciphisa ubomi bokudinwa.

Abanye abavelisi bazama ukufihla oku ngokuguqula inqaku lejometri ukuba libe ndlongondlongo, kodwa oko kunokukhokelela kweminye imiba efana nokupakishwa kwetshiphu okanye ukugrumba okungazinzanga. Sisenzo sokulinganisa. Isisombululo sangempela sezicelo ezibalulekileyo zidla ngokubandakanya ukujonga i-drilling kunye nokukhuselwa kwe-corrosion njengemisebenzi eyahlukileyo-mhlawumbi ukusebenzisa umngxuma owenziwe ngaphambili okanye inkqubo yokukhusela i-corrosion yecandelo lokubumba intambo.

IiNyaniso zokusiNgqongileyo vs. Uvavanyo lwaseLab

Iimvavanyo zokutshiza ityuwa (njenge-ASTM B117) zisemgangathweni, kodwa zinokulahlekisa kula macandelo. A I-electro-geriansed I-hex head drill screw inokudlula iiyure ezingama-96 zesitshizi setyuwa esinemibala ephaphazelayo kwiphaneli ecaba. Kodwa faka eso sikrufu sinye kwindawo eguquguqukayo, ethwele umthwalo kunye neentsimbi ezingafaniyo (umzekelo, kwi-aluminiyam), kwaye wazisa i-galvanic corrosion. I-zinc iyazincama, ilungile, kodwa yenza oko ngesantya esikhawulezayo. Iwotshi yokuqina iphawula ngokukhawuleza okukhulu.

Oku sikufunde kwiprojekthi yokufakwa kwamandla elanga. Izikrufu, i-electro-galvanized, iqhotyoshelwe izibiyeli zentsimbi kwiireyile ze-aluminium. Iingxelo zaseLebhu zazicacile zonke. Ebaleni, kwisithuba seminyaka emibini, umhlwa ombi wegalvanic kumdibaniso okhokelele ekuthotyweni kwamandla. I-zinc yayiphelile, kungekhona kwi-uniform exposure, kodwa kuhlaselo lwe-galvanic ekujoliswe kulo. Sifunda ntoni? Imekobume ayilogumbi lovavanyo. Ibandakanya izixhobo ozibophayo.

Apha kulapho ukusebenziseka komthengisi omnye kwindawo enkulu yolungiselelo kubonisa ixabiso layo. Inkampani efana ne-Handan Zitai, emi kanye kweyona siseko sikhulu saseTshayina esinokufikelela ngokuthe ngqo kuthungelwano lukaloliwe olukhulu kunye nohola wendlela, inethala leencwadi elibanzi elisesandleni. Unokuba nencoko malunga nokutshintshela kwi-zinc-flake coated screw okanye ukongeza iwasha yombingelelo ngokulula ngakumbi kuba bajongana neqela elipheleleyo lemingeni yokubola evela kubathengi kwihlabathi liphela, hayi nje inkcazo yethiyori.

Ngoko, Ngaba Ihlala Yomelele? Impendulo enemiqathango

Ukuqina kwe electro-galvanized hexagonal drill thread isikrufu sinemiqathango ephezulu. Ukusetyenziswa kwezakhiwo zangaphakathi, ezomileyo, ezingabalulekanga apho imbonakalo ibalulekile? Yomelele ngokugqibeleleyo. Kuyo nayiphi na into ebandakanya imozulu, ukungcangcazela, iintsimbi ezingafaniyo, okanye iimfuno zomthwalo obambekayo ophezulu, ukuqina kwayo kunemida ecacileyo, enokuxelwa kwangaphambili. I-electro-galvanizing isithintelo se-cosmetic kunye nesimodareyitha somhlwa ophazamiseka ngokusebenzayo ngumsebenzi we-drill thread kunye noxinzelelo lwe-hex drive.

Intshukumo yobuchwephesha kukuyeka ukucinga ngayo njengemveliso emanyeneyo. Yahlula ukuqina kwayo ibe ngamacandelo: ingqibelelo yentloko/yedrive, ukusebenza kwangaphambili kwentambo, kunye nokhuseleko lomhlwa. Cacisa okanye ukhethe ngokusekwe kwelona khonkco libuthathaka isicelo sakho siyakuveza. Ngamanye amaxesha, olona khetho lungcono kukuqhawula imisebenzi-sebenzisa umngxuma owenziwe ngaphambili kunye ne-screw-forming screw kunye ne-coating eyomeleleyo, njenge-flake ye-zinc mechanical.

Ekugqibeleni, yehla kubunjineli besicelo esinyanisekileyo. I-fastener ayikho nje ipini ebamba izinto kunye. Yinkqubo yonxibelelwano-ukuqhuba, ukubhola, intambo, iqhosha kunye nokukhusela. I-Electro-galvanizing idilesi enye inxalenye yaloo nkqubo kunye nesisombululo esicacileyo, esineendleko, kodwa ngokuqhelekileyo yenza njalo ngeendleko zabanye. Ukuqonda ukuba urhwebo linyathelo lokuqala lokuchaza into eya kuhlala ihleli.
