Zinc-plated intambo enehexagonal drill ukuqina? 

Uyabona le combo-i-zinc emnyama, intloko ye-hex, umsonto we-drill point-iphoswe ngeenxa zonke kwi-specs lonke ixesha. Ingqikelelo ekhawulezileyo kukuba yinto nje eyomeleleyo, inguqulelo enganyangekiyo ekumdleni yesibophelelo sakho esiqhelekileyo se-zinc-plated. Kodwa kulapho kwenzeka impazamo yokuqala. Ukuqina akuyiyo ipropathi enye onokuthi uyigximfize kwibhokisi; sisiphumo esingcolileyo senkqubo yokucwenga, izinto ezisisiseko, isenzo sokwenza intambo, kwaye ngokunyanisekileyo, indawo oyiphosa kuyo. Ndibone iiprojekthi ezininzi kakhulu apho ezi zichaziweyo ukuba zisetyenziswe ngaphandle kwaye zasilela kwangaphambi kwexesha kuba umntu wajonga ibhokisi ekwaziyo ukumelana nomhlwa engakhange aqonde iileya ezibandakanyekayo.

Ukucacisa iZinc emnyama Gqiba

Masiqale ngokugqiba. I-zinc plating emnyama ayikho nje i-zinc eqhelekileyo efakwe kwidayi emnyama. Ngokuqhelekileyo ngumaleko we-zinc olandelwa yingubo yokuguqula i-chromate emnyama. Lo maleko wechromate yeyona nto inika umbala kwaye yongeza ukongezwa komda ekuxhathiseni umhlwa. Igama eliphambili ngumda. Ngokwamava am, oku kugqitywa kumnyama kunika mhlawumbi i-96 kwiiyure ze-120 zokuxhathisa ityuwa ngaphambi kokuba ubone i-rust emhlophe (i-zinc corrosion). Ayisiyonto enzima yokwaleka njengokwenza igalvanizing ngoomatshini okanye i-hot-dip galvanizing.

Ichromate emnyama ithe chu kwaye inokuba brittle. Ukuba uqhuba isikhonkwane sokuzibhobhoza ngolu hlobo, ukukhuhlana kunye nobushushu obuveliswe kwindawo yokubhola inokutshisa okanye iqhekeze umaleko wechromate kanye kwincam nakwimisonto ekhokelayo. Ushiywe ngumqobo oyekelelweyo ukusuka ekuhambeni. Ndikhumbula ibhetshi yezikrufu zokuphahla, ubungakanani be-M8, apho sasinomhlwa obomvu ongaguqukiyo ovela kwincam ye-drill emva nje kwesizini enye, ngelixa intloko ye-hex isabonakala ilungile. Isenzo sokomba sinxibe ukhuseleko kude.

Enye i-nuance bubunzima bokugquma. Ugqibo olulungileyo, oluqinileyo lwezinki olumnyama olusuka kwiprosesa ebekekileyo lunokuba ne-zinc layer ye-8-12 microns kunye nechromate. Kodwa ndivavanye iisampulu ezivela kubaboneleli ngokubanzi apho ubukhulu bubonke babungaphantsi kwe-5 microns. Ngaphantsi kwe-micrometer, ibonakala ilungile, kodwa kwimeko yokwenyani okanye i-abrasion, ihambile ngemizuzwana. Kulapho umthombo ubalulekileyo. Umenzi othanda I-Sunnian Zitai Festener Fishaner Comment Com., esekelwe kwi-hub enkulu ye-fastener yase-China e-Yongnian, ngokuqhelekileyo inolawulo olungqongqo lwenkqubo ngenxa yomthamo kunye neziseko apho. Ukujonga iinkcukacha zabo zenkqubo kwisiza esinje https //wwww.ziitasteners.com inokukunika isiseko malunga nokuba ukugqiba kwemizimveliso kufanele kube yintoni.

Intloko yeHex kunye neDrill Point Dynamic

Intloko ye-hexagonal imalunga nokudluliselwa kwe-torque kunye nokuzinza kwe-drive. Akukho nto imangalisayo apho. Kodwa yidibanise nenqaku lokubhola, kwaye wazisa umahluko omkhulu wokuqina. Umsonto apha udla ngokuba yi-spaced-out, ifomu enobudlova eyenzelwe ukusika isinyithi. Ukuqina kwe Intambo yokuqhuba ngokwayo incinci malunga nokugquma kunye nokunye malunga nentsimbi engaphantsi kunye nonyango lobushushu.

Inqaku eliqhelekileyo lokungaphumeleli lutshintsho olusuka kwi-drill flute ukuya kumsonto wokuqala. Ukuba unyango lobushushu lucimile, loo ndawo inokuba nzima kakhulu kwaye inkeneke, ibangele ukuba incam ukuba irhoxe phantsi koxinzelelo oluphezulu, ngakumbi kwi-substrates eqinile efana ne-steel purlins. Ndineebhokisi apho i-5% ye-screws yayiza kuhlutha ngexesha lofakelo. Oyena nobangela ulandelelanisa ubushushu obungafanelekanga emva kokuqina, ishiya intsimbi inobulukhuni obuphezulu kodwa kungekho kuqina. I-zinc plating emnyama ayenzi nto ukuthintela oku; ngumba ongundoqo wesayensi.

Ngaphaya koko, ukugrumba kwenza i-swarf-shavings yentsimbi. Ezi shavings zishushu, zibukhali zinokufakwa kwi-hex drive socket okanye inyongo ngokuchasene nemisonto esandul' ukucandwa, ikhuhla ngokwasemzimbeni isambatho. Isiqhoboshi esenziwe kakuhle sinokuba ne-wax yokuthambisa phezu kwe-plating (isiqhelo esiqhelekileyo) ukunciphisa ukukhuhlana kunye nokukhusela ukugquma ngexesha lofakelo. Ukuba i-screw ivakalelwa kukuba yomile iphuma ebhokisini, i-plating iya kuthatha ukubetha ngexesha lokuqhuba.

I-Corrosion yeHlabathi yokwenyani: Ayifani

Ukuqina kwi-specs yinombolo yelebhu. Ukuqina kwisiza yi-patchwork. Ndisebenzise ibhetshi yezikrufu ezimnyama ze-zinc-plated hex head drill zokuqhoboshela intsimbi yecala kwisakhelo sogcino kwindawo eselunxwemeni. Umlinganiselo wokutshiza ityuwa yayiziyure ezili-100. Enyanisweni, emva kweenyanga ezili-18, sasinemephu ecacileyo yokusilela. Izikrweqe kwicala elibheke ngasemoyeni, elichaphazwe yimvula libonise umhlwa ocacileyo omhlophe kunye nomhlwa obomvu kwimisonto. Izikrufu phantsi kwe-overhang, ubukhulu becala bomile, zikhangeleka zintsha. I I-winc-idweliswe ukugqiba akuzange kusilele ngokufanayo.

Isifundo yayikukuba ukukhuselwa kwechromate koyiswa ngokulula kukufuma kunye netyuwa rhoqo. Yingubo yombingelelo, ngoko iya kuthotywa. Kwimeko enjalo, ukucacisa ukugqitywa kwe-zinc emnyama ngaphandle kwesicwangciso esiqinileyo sokulungiswa kukulungiswa kwexesha elifutshane. Sagqiba ukutshintshela kwi-galvanized coating enzima kunye ne-sealant kwisigaba esilandelayo, samkele i-bump yeendleko zobomi obude.

Enye imeko kukuvezwa kweekhemikhali. Akukho nakwimizi-mveliso, yinto eqhelekileyo. Ndabona iprojekthi ye-pergola apho umxhasi wasebenzisa izikrufu ezimnyama ze-zinc ukuze afake iibhodi zemisedare. I-tannins kunye ne-asidi yendalo evela kumsedare, ngakumbi xa imanzi, ikhawuleza ukubola ngesantya esothusayo. Ukugqiba okumnyama kungcolise iinkuni ngeeruphu ezibalekayo. Ukukhethwa kobuhle kwaba kukungaphumeleli kokusebenza. Iplating ayizange yenzelwe olo hlobo lwentsebenziswano yeekhemikhali.

IKhadi lasendle lokuVelisa kunye nokuFumana

Le yinxalenye ongayiboniyo kwiphepha elithile. Ukomelela kwesibophelelo sokugqibela kutshixiwe kumgangatho wefektri. Kusemgangathweni wentonga yocingo, ukuchaneka kwentambo yokufa, iqondo lokushisa kunye nekhemikhali yeebhafu zokucoca, kunye nokuhambelana kwe-oven yokunyanga. Umvelisi omkhulu obekwe kwindawo egxile kwimveliso, njengeHandan Zitai kwiSithili saseYongnian, uhlala enenzuzo. Ukuba sembindini wesiseko secandelo eliqhelekileyo laseTshayina, elikufuphi neendlela ezinkulu zokuthutha, zidityaniswe kwikhonkco lokubonelela elifuna umthamo kunye nokuhambelana, ukuba akusoloko kumgangatho ophezulu, umgangatho. Yabo iwebhsayithi Isenokungakhwazi iprimiyamu, kodwa kwizicelo ezininzi zorhwebo, imveliso yazo imele isiqhelo esithembekileyo, somgangatho woshishino.

Ndiyalele izikrufu ezifanayo ezimnyama ze-zinc hex ezivela kubaboneleli ababini abahlukeneyo. Ibhetshi enye yaba nesiphelo esigudileyo, nesimnyama; enye yayigqabhukile inebala elimfusa. Uvavanyo lwesitshizi setyuwa lubonise umahluko weyure ezingama-40 kwimbonakalo yomhlwa emhlophe. Ibhetshi ebomvu ibinomaleko wechromate ongangqinelaniyo, ekunokwenzeka ukuba usuka kukuphazamiseka kwebhafu okanye ukosuleleka. Imilinganiselo yokuziphatha? Ileyibhile ye-zinc emnyama ayisosiqinisekiso. Kuya kufuneka ulungele umthengisi wakho, mhlawumbi uphicothe umgca wabo wokucoca ukuba iprojekthi ibalulekile.

Uxinzelelo lweendleko luhlala luhenda abavelisi ukuba banqumle iikona-i-zinc encinci, i-chromate salts engabizi kakhulu, ukutsiba amanyathelo okuhlanjululwa okukhokelela kwi-asidi eseleyo ehlasela i-coating ngaphakathi. Uphawu oluxelayo yintsalela emnyama ephuma kwiiglavu zakho. Oko kukubambelela kakubi kunye nokugquma okuya kugqabhuka phantsi koxinzelelo.

Ke, sithini iSigwebo soKuhlala ixesha elide?

Ixhomekeke. Kwiindawo ezingaphakathi, ezomileyo, okanye ezifumileyo ngamaxesha athile, zenziwe ngokufanelekileyo I-winc-i-winc-i-thexagonal ye-hexagonal drill ifastener yomelele ngokwaneleyo. Inika ukuxhathisa okufanelekileyo kwe-corrosion kunye nenkangeleko ecocekileyo, ephantsi. Intloko ye-hex inika isakhono esilungileyo se-torque, kwaye indawo ye-drill inika ukufakwa kwenyathelo elinye. Yinto eyomeleleyo, injongo-jikelele yorhwebo/ishishini lokuqinisa.

Kwimekobume erhabaxa—ukufuma rhoqo, ityuwa, ukuchanabeka kwimichiza, okanye ukukrazuka kakhulu—ukuhlala kwayo kulinganiselwe. I-coating incinci kakhulu kwaye isengozini kakhulu kumonakalo womatshini ngexesha lofakelo kunye nokuhlaselwa kokusingqongileyo emva koko. Kwezi meko, uthenga kumjikelo wesondlo okanye wamkela ubomi obufutshane benkonzo.

Umnxeba wokugqibela ufika kule nto: ngaba uyisebenzisela ukubonakala kwayo kunye nokusebenza okuphakathi, okanye ngaba uthembele kuyo ngokubalulekileyo, ukunyaniseka kwesakhiwo sexesha elide? Ukuba yeyokugqibela, i-zinc emnyama kumsonto we-drill kufuneka ikunikeze ikhefu. Kusenokufuneka unyuke uye kwi-screw eshushu yokudipha nge-drill bit eyahlukileyo, okanye ucinge ngentsimbi engatyiwayo, ngaphandle kweendleko. Umsonto we-hex drill lihashe elisebenzayo, kodwa idyasi emnyama ye-zinc yiyunifomu yayo yokunxiba, hayi isikrweqe sayo sokulwa. Yicacise ngamehlo acacileyo kwimida yayo, kwaye soloko uvavanya ibhetshi yesampulu kweyona sicelo ngaphambi kokuba uzibophelele kumaqhekeza angama-10,000.
