I-zinc-plated countersunk cross bolts ezimnyama: zihlala ziqinile? 

Ukuba ubuza ukuba ngaba i-zinc-plated countersunk cross bolts emnyama iqinile, impendulo emfutshane kukuba: kuxhomekeke ngokupheleleyo apho uyisebenzisa khona. Ndibone i-specs ezininzi kakhulu zibiza i-zinc emnyama njengento yokubamba-konke ukuxhathisa ukubola kunye ne-aesthetics, kuphela ukuba iindawo zisilele kwangaphambi kwexesha kwindawo engalunganga. I-plating ngokwayo ayilona ikhonkco elibuthathaka; kukulindela ukuba sisisombululo sehlabathi.

Yintoni eneneni iZinc eziMnyama ezithetha ngayo kuMgangatho

Ngokwesiqhelo, i-zinc emnyama ihlala ibhekisa kwinkqubo yokufakwa kwe-zinc elandelwa yingubo yokuguqula i-chromate emnyama. Lo ayisosithintelo esingqindilili, esomeleleyo esifana nokufaka igalvanizing yediphu eshushu. Ngumaleko obhityileyo wedini. I-chromate emnyama inika umbala kwaye yongeza umaleko omncinci wokuxhathisa ukubola, kodwa umsebenzi wayo ophambili udla ngokuba yi-aesthetics-ukunika iyunifomu, ukugqiba okumnyama okujongeka kwimizi-mveliso okanye ukunciphisa ukukhanya. Ukhuseleko lwangempela luvela kwi-zinc ephantsi, eya kuthi i-corrode ngokuncama ukukhusela i-substrate yensimbi. Ke, ukuqina apha kumalunga nokukwazi kwe-zinc ukuzincama kancinci.

Ndikhumbula ibhetshi evela kwiprojekthi kwiminyaka eyadlulayo, eyayisetyenziswa kwizivalo zombane zangaphakathi kwigumbi leseva elilawulwa yimozulu. Basebenza ngokugqibeleleyo kangangeminyaka—kungekho mhlwa, iintloko zahlala zicocekile. Kodwa le yindawo entle. Umzuzu uzisa ukufuma, iityuwa, okanye imijikelo ye-thermal rhoqo, ibali liyatshintsha. Ingubo emnyama inokufihla izigaba zokuqala zomhlwa omhlophe (i-zinc oxide), eyingxaki. Usenokungaboni ukusilela ukuza kude kube kuhambele phambili.

Uyilo lwentloko ye-countersunk yongeza omnye umaleko kumbuzo wokuqina. Ukugqibezela okugungxulwayo, uhlala ulungisa okanye ucinezela intloko, enokuthi ibe mncinci okanye yophule iplating emaphethelweni. Ukuba iplating ayihambelani apho-kwaye ihlala injalo-sisiqalo sakho somhlwa obomvu. Ndiye ndahlola iindawo apho umhlwa waqala khona ngokuchanekileyo kumda obukhali wentloko ye-countersunk, indawo yokungaphumeleli kweklasikhi engaphezulu kwejometri kunekhemistri yokucoca.

I-Cross Recess: Into eZithekileyo eZimeleyo

Wonke umntu ugxile kwi-plating yangaphandle, kodwa inkqubo yokuqhuba ibalulekile ekusebenzeni okuzinzileyo. Intloko kaPhillips (ikhefu elinqamlezayo), ngakumbi kwibholithi eshiyiweyo, ineendawo zoxinzelelo zendalo. Ngexesha lofakelo, ukuba i-bit yomqhubi ayihlali ngokugqibeleleyo okanye i-torque iphezulu, ubeka umngcipheko wokuphuma-i-bit slipping kunye nokukhulula ikhefu. Ibholithi ekhutshiweyo ayihlali ixesha elide nokuba ilunge kangakanani na ukumelana nokudleka kwayo. Oku kwenza umgangatho wokubunjwa kwekhefu phambili. Umnqamlezo ongekho mgangathweni, ongekho nzulu, okanye ongekho embindini uya kusilela ngexesha lofakelo, nto leyo eyenza ukuba ibholi ibe lilize.

Oku sikufunde kabuhlungu kumgca wokudityaniswa kusetyenziswa abaqhubi abazenzekelayo. Ukuthunyelwa kweebholithi ezimnyama ze-zinc-plated countersunk, ezithathwe kuphela ngexabiso eliphantsi, bezinobunzulu obungahambelaniyo bekhefu. Abaqhubi baqhubeka betyibilika, bekhulula iintloko, bemisa nomgca. Ukumelana nomhlwa kwakungabalulekanga; iibholiti zasilela kwinqanaba lokuqhuba. Kusinyanzele ukuba sivavanye ababoneleli kungekuphela nje kwiicerti zokucoca, kodwa kwiintloko zabo ezibandayo kunye nokunyamezelana ngomatshini ngexesha lekhefu. Inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., esekwe kwi-hub enkulu yemveliso ye-fastener yase-China, ngokuqhelekileyo inobuchule besixhobo sokwenziwa kweempawu zokuqhuba, okubaluleke kakhulu njengokugqitywa.

Kungenxa yoko nasiphi na isicelo esibalulekileyo, ndingakhankanya i-drive yokusebenza ephezulu njenge-Pozidriv okanye i-Torx yeentloko ze-countersunk, kodwa oko akusoloko kukhetho xa ujongene noyilo lwelifa okanye imigangatho ethile ebiza umnqamlezo wePhillips.

Ubume behlabathi bokwenyani: Apho basebenza khona nalapho bangasebenziyo

Makhe sicacise. Ukusetyenziswa kwangaphakathi, okomileyo-i-electronics, ifenitshala yangaphakathi, i-drywall framing kwizakhiwo ezilawulwa yimozulu-ezi bholithi ziqinile ngokugqibeleleyo. Ukugqiba okumnyama kubambe phezulu, kwaye i-zinc inika ukhuseleko olwaneleyo ngokuchasene nokufuma okuzenzekelayo. Ndizisebenzisile kwiimpawu ezifana ne-ITW Shakeproof okanye zifunyenwe kubathengisi abaninzi eYongnian kwimisebenzi enjalo ngaphandle kwemiba.

Indawo engwevu ikhuselwe ukusetyenziswa kwangaphandle-njengaphantsi kwe-eves, kwi-soffits, okanye ngaphakathi kwemoto. Apha, ungafumana ukujiya, ukufuma ngamaxesha athile. Ukuqina kuba ngumsebenzi wexesha. Ndibabonile kwiminyaka emi-2 ukuya kweyesi-3 ngaphambi kokubonisa umhlwa omhlophe obalulekileyo, kwaye mhlawumbi i-4-5 ngaphambi kokuba kuvele umhlwa obomvu emaphethelweni. Ihlala ixesha elide kwi-non-structural, icandelo elinokutshintshwa, kodwa kungekhona ukufakela isigxina.

Iimekobume ezirhabaxa zinzima. Iindawo ezingaselunxwemeni ezinetyuwa yokutshiza, ukusetyenziswa kweendlela ezineetyuwa ze-icing, okanye iisetingi zemizi-mveliso ezinomswakama ophezulu ziya kudla ngokutyalwa kwe-zinc eqhelekileyo kwiinyanga. I-black coating inokuthi ifake i-micropore, isantya somhlwa. Kwezi meko, ukuzibiza ngokuba zizinzileyo yimpazamo. Udinga i-coat enzima efana ne-plating yomatshini, i-galvanizing yediphu eshushu, okanye ukutshintshela kwintsimbi engenasici.

Umahluko kuMboneleli kunye neNgxaki yeBatshi elungileyo

Ukuqina akukho malunga ne-spec; imalunga nemveliso engaguqukiyo. Ubuninzi be-zinc layer (kulinganiswa kwii-microns) kunye nomgangatho wenkqubo yokuguqula i-chromate iyahluka ngokungaqhelekanga phakathi kwababoneleli. Umenzi ohloniphekileyo uya kulandela imigangatho efana ne-ASTM B633 ye-zinc plating, echaza ubuncinci bobunzima (umzekelo, i-5 microns ye-SC2 yokusetyenziswa kwezorhwebo). Izinto ezininzi ezisuka kumazwe angaphandle ezininzi zitsiba ulawulo olululo lwenkqubo.

Ungajonga iwebhusayithi yabo, njengaye https //wwww.ziitasteners.com, ukubona ukuba bachaza iinkqubo zabo kunye nolawulo lomgangatho. Umenzi obekwe kwisiseko esikhulu semveliso efana neYongnian, enofikelelo kumatyathanga obonelelo adibeneyo, uhlala enokungaguquguquki okungcono. Ukukhankanywa kuka-Handan Zitai ngokuba kwesona siseko sikhulu sesiseko sicebisa ukuba banesiseko sesiseko, kodwa kusafuneka uqinisekise ulawulo lwabo lwelayini yokucwenga. Ndineebholiti ezifanayo ezivela kwiqashiso ezimbini ezahlukeneyo zenza ngokwahlukileyo ngokupheleleyo kuvavanyo olufanayo lokutshiza ityuwa.

I-takeway? Soloko ucela isatifikethi sovavanyo lwebhetshi yokucwenga, ngakumbi kwiiprojekthi zangaphandle. Musa ukucinga ukuba i-zinc emnyama ithetha into efanayo kuyo yonke indawo.

Ngoko, Ngaba Zihlala Zihleli? Isigqibo Esisebenzayo

Nguewe onemiqathango. Ngelungelo, isicelo esilawulwayo, i-zinc-plated countersunk cross bolts emnyama zinika ibhalansi elungileyo yokumelana nokubola, ubuhle kunye neendleko. Ukomelela kwabo kwamkelekile. Kodwa ayisosisombululo esilinganayo. I-plating incinci kwaye idini; ikhefu lomnqamlezo linokuba yindawo ebuthathaka ukuba umgangatho uphantsi.

Umthetho wam wesithupha: zisebenzise ngaphakathi ngaphandle kokucinga okwesibini. Ukusetyenziswa kwangaphandle okukhuselweyo, lindela ubomi benkonzo mhlawumbi iminyaka emi-3-5, kunye nesicwangciso sokuhlolwa okanye ukutshintshwa. Kuso nasiphi na isicelo esiqatha okanye esibalulekileyo, cacisa isiphelo esahlukileyo okanye imathiriyeli ngokupheleleyo. Kwaye ungaze, ukhe unikele umgangatho wokwenza umgangatho ngexabiso eliphantsi-ibholithi ekhutshiweyo yibholithi engaphumeleliyo, nokuba ityatyekwe njani.

Ekugqibeleni, ukuqina yipropathi yenkqubo, kungekhona nje into ephathekayo. Kuxhomekeke kwimeko-bume, ubuchule bofakelo, kunye nomgangatho wokuvelisa ongaguqukiyo emva kwebholithi ethile esandleni sakho. Ukugqitywa kwe-zinc emnyama yinto nje enye eguquguqukayo kuloo nxaki.
