Dub zinc-plated countersunk cross bolts: ruaj? 

Yog tias koj tab tom nug seb dub zinc-plated countersunk cross bolts yog qhov ruaj khov, cov lus teb luv luv yog: nws nyob ntawm qhov koj siv lawv. Kuv tau pom ntau qhov tshwj xeeb hu rau dub zinc raws li kev ntes-tag nrho rau kev tiv thaiv corrosion thiab zoo nkauj, tsuas yog rau cov khoom ua tsis tiav ntxov hauv qhov chaw tsis raug. Lub plating nws tus kheej tsis yog qhov tsis muaj zog txuas; nws yog qhov kev cia siab tias nws yog kev daws teeb meem universal.

Dab tsi Dub Zinc txhais tau tias nyob hauv pem teb

Hauv kev xyaum, zinc dub feem ntau yog hais txog zinc plating txheej txheem ua raws li cov xim dub chromate hloov dua siab tshiab. Qhov no tsis yog tuab, muaj zog tiv thaiv zoo li kub-dip galvanizing. Nws yog txheej nyias nyias. Cov xim dub chromate muab cov xim thiab ntxiv cov txheej txheem me me ntawm kev tiv thaiv corrosion, tab sis nws txoj haujlwm tseem ceeb yog feem ntau tsuas yog kev zoo nkauj - muab cov khaub ncaws, tsaus nti uas zoo nkaus li muaj lossis txo lub teeb pom kev zoo. Qhov kev tiv thaiv tiag tiag yog los ntawm cov zinc hauv qab, uas yuav txia corrode los tiv thaiv cov hlau substrate. Yog li, durability ntawm no yog hais txog zinc lub peev xwm los txi nws tus kheej maj mam.

Kuv nco qab ib pawg los ntawm ib qhov project xyoo dhau los, siv rau sab hauv hluav taws xob enclosures nyob rau hauv ib chav neeg rau zaub mov tswj huab cua. Lawv ua tau zoo rau ntau xyoo - tsis muaj xeb, lub taub hau nyob twj ywm huv. Tab sis qhov ntawd yog ib puag ncig zoo. Lub sijhawm koj qhia txog kev ya raws, ntsev, lossis kev hloov pauv ntau zaus, zaj dab neeg hloov. Cov txheej txheej dub tuaj yeem zais cov theem pib ntawm xeb dawb (zinc oxide), uas yog qhov teeb meem. Tej zaum koj yuav tsis pom qhov ua tsis tiav los txog thaum nws nce qib.

Lub countersunk taub hau tsim ntxiv lwm txheej rau cov lus nug durability. Rau kev ua kom tiav, koj feem ntau machining lossis stamping lub taub hau, uas tuaj yeem nyias lossis ua txhaum cov plating ntawm cov npoo. Yog tias cov plating tsis sib haum nyob ntawd - thiab nws feem ntau yog - qhov ntawd yog koj qhov pib ntawm xeb liab. Kuv tau tshuaj xyuas qhov chaw uas xeb tau pib meej meej ntawm ntug ntse ntawm lub taub hau countersunk, ib qho kev ua tsis tiav classic uas yog ntau txog geometry dua li plating chemistry.

Kev Hla Hla: Qhov Tseem Ceeb Tseem Ceeb

Txhua tus neeg tsom mus rau sab nrauv plating, tab sis lub zog tsav yog qhov tseem ceeb rau kev ua haujlwm ruaj khov. Lub Phillips (hla qhov chaw so) lub taub hau, tshwj xeeb tshaj yog nyob rau ntawm lub qhov rooj xauv, muaj cov ntsiab lus kev ntxhov siab. Thaum lub sij hawm installation, yog hais tias tus neeg tsav tsheb me ntsis tsis zaum zoo tag nrho los yog lub torque siab, koj yuav muaj kev pheej hmoo cam-tawm-lub me ntsis slipping thiab stripping lub recess. Ib tug stripped bolt tsis ruaj txawm tias nws zoo corrosion kuj zoo npaum li cas. Qhov no ua rau qhov zoo ntawm qhov recess tsim tseem ceeb. Ib qho kev tsim tsis zoo, ntiav, lossis sab hauv nruab nrab yuav ua tsis tau thaum lub sijhawm teeb tsa, ua rau lub bolt tsis muaj txiaj ntsig.

Peb kawm qhov no nyuaj ntawm txoj kab sib dhos uas siv cov tsav tsheb tsis siv neeg. Kev xa khoom ntawm cov xim dub zinc-plated countersunk bolts, tau los ntawm tus nqi qis, muaj qhov tsis sib haum xeeb qhov tob. Cov neeg tsav tsheb tau nrawm nrawm, rub lub taub hau, thiab nres txoj kab. Kev tiv thaiv corrosion tsis cuam tshuam; cov bolts ua tsis tau tejyam nyob rau theem tsav. Nws yuam peb cov neeg muab khoom vet tsis yog ntawm daim ntawv pov thawj plating, tab sis ntawm lawv lub taub hau txias thiab machining tolerances rau qhov chaw so. Ib lub tuam txhab zoo li HANDAN ZITAI FREWER RAUG UA MOV., Ltd., raws li nyob rau hauv Tuam Tshoj tus loj fastener ntau lawm hub, feem ntau muaj cov cuab yeej kev txawj ntse rau zoo ib yam tsav feature tsim, uas yog ib qho tseem ceeb raws li qhov kawg.

Qhov no yog vim li cas rau txhua daim ntawv thov tseem ceeb, kuv xav qhia kom muaj kev ua tau zoo dua zoo li Pozidriv lossis txawm tias Torx rau countersunk taub hau, tab sis qhov ntawd tsis yog ib qho kev xaiv thaum cuam tshuam nrog cov qauv qub qub lossis cov qauv tshwj xeeb uas hu rau Phillips cross.

Lub ntiaj teb ib puag ncig tiag tiag: Lawv ua haujlwm qhov twg thiab qhov twg lawv tsis ua

Cia peb kawm tshwj xeeb. Rau sab hauv tsev, qhuav daim ntaub ntawv - hluav taws xob, rooj tog zaum sab hauv, phab ntsa ntub dej hauv cov tsev tswj kev nyab xeeb - cov bolts no zoo kawg nkaus. Cov dub tiav tuav, thiab zinc muab kev tiv thaiv txaus tiv thaiv cov av noo. Kuv tau siv lawv los ntawm cov npe xws li ITW Shakeproof lossis los ntawm cov chaw muag khoom loj hauv Yongnian rau cov haujlwm zoo li no tsis muaj teeb meem.

Cov cheeb tsam grey yog kev siv sab nraum zoov-zoo li hauv qab eaves, hauv soffits, lossis hauv tsheb sab hauv. Ntawm no, koj yuav tau txais condensation, qee zaus noo noo. Durability dhau los ua lub sijhawm ua haujlwm. Kuv tau pom lawv dhau 2-3 xyoos ua ntej pom cov xeb dawb tseem ceeb, thiab tej zaum 4-5 ua ntej xeb liab tshwm ntawm ntug. Nws yog qhov ruaj khov rau cov khoom siv tsis yog cov qauv, hloov tau, tab sis tsis yog rau kev txhim kho mus tas li.

Ib puag ncig hnyav yog qhov nyuaj tsis muaj. Cov ntug dej hiav txwv nrog cov tshuaj tsuag ntsev, kev siv txoj kev nrog cov ntsev de-icing, los yog cov chaw ua haujlwm siab yuav noj los ntawm cov txheej txheem dub zinc plating hauv lub hlis. Cov txheej dub tej zaum yuav txawm micropore, ua kom corrosion. Hauv cov xwm txheej no, hu rau lawv ruaj khov yog qhov yuam kev. Koj xav tau cov txheej hnyav dua li cov tshuab plating, kub-dip galvanizing, lossis hloov mus rau stainless hlau.

Tus neeg muab khoom sib txawv thiab qhov teeb meem zoo Batch

Durability tsis yog hais txog cov spec; nws yog hais txog kev tsim khoom sib xws. Qhov tuab ntawm zinc txheej ( ntsuas hauv microns) thiab qhov zoo ntawm cov txheej txheem hloov pauv chromate sib txawv ntawm cov neeg muag khoom. Lub tuam txhab muaj npe nrov yuav ua raws li cov qauv zoo li ASTM B633 rau zinc plating, qhia qhov tsawg kawg nkaus thickness (xws li, 5 microns rau SC2 coj mus muag siv). Ntau pheej yig imports hla kev tswj kom raug.

Koj tuaj yeem tshawb xyuas lawv lub vev xaib, zoo li https://www.zitaifasteners.com, saib seb lawv nthuav dav lawv cov txheej txheem thiab kev tswj kom zoo. Ib lub chaw tsim khoom nyob rau hauv lub hauv paus loj xws li Yongnian, nrog rau kev nkag mus rau cov khoom siv sib xyaw ua ke, feem ntau muaj qhov sib xws zoo dua. Handan Zitai cov lus hais txog kev ua nyob rau hauv tus qauv loj tshaj plaws hauv paus qhia tias lawv muaj cov txheej txheem, tab sis koj tseem yuav tsum tau txheeb xyuas lawv cov kev tswj hwm plating tshwj xeeb. Kuv tau muaj cov ntsia hlau zoo ib yam los ntawm ob qhov sib txawv ua qhov sib txawv kiag li hauv tib qhov kev ntsuas ntsev-txhaj tshuaj.

Qhov takeaway? Ib txwm thov kom muaj daim ntawv pov thawj rau cov plating batch, tshwj xeeb tshaj yog rau cov haujlwm sab nraum zoov. Tsis txhob xav tias dub zinc txhais tau tias tib yam nyob txhua qhov chaw.

Yog li, Puas Yog Lawv Ua Haujlwm? Kev Txiav Txim Siab

Nws yog conditional muaj. Rau txoj cai, tswj daim ntawv thov, dub zinc-plated countersunk cross bolts muab qhov sib npaug zoo ntawm kev tiv thaiv corrosion, zoo nkauj, thiab tus nqi. Lawv durability yog txais. Tab sis lawv tsis yog ib qho loj-haum-tag nrho cov kev daws teeb meem. Plating yog nyias thiab txi; tus ntoo khaub lig recess tuaj yeem yog qhov tsis muaj zog yog tias qhov tsis zoo.

Kuv txoj cai ntawm tus ntiv tes xoo: siv lawv sab hauv tsev yam tsis muaj kev xav thib ob. Rau kev siv sab nraum zoov, cia siab tias yuav muaj kev pab cuam lub neej ntawm 3-5 xyoos, thiab npaj rau kev tshuaj xyuas lossis hloov. Rau ib daim ntawv thov hnyav lossis qhov tseem ceeb, qhia qhov sib txawv lossis cov khoom siv tag nrho. Thiab tsis tau, puas tau fij tus cwj pwm zoo rau tus nqi pheej yig dua - lub bolt stripped yog ib qho kev ua tsis tiav, tsis hais nws txheej.

Thaum kawg, durability yog ib qho cuab yeej cuab tam, tsis yog ib qho khoom siv xwb. Nws nyob ntawm ib puag ncig, cov txheej txheem kev teeb tsa, thiab kev tsim khoom zoo ib yam tom qab cov ntsia hlau tshwj xeeb hauv koj txhais tes. Cov zinc dub tiav tsuas yog ib qho sib txawv ntawm qhov sib npaug.
