Cov lus tsocai rau koj cov khoom siv rov qab hais tias cov tshuaj ntsev ntsev: 240 teev, ASTM B117. Cov fittings zaum ntawm qhov chaw nres nkoj, lub tshuab poob qis, thiab lub thawv ntawv rov qab tus lej. Cov neeg saib xyuas kev saib xyuas feem ntau kos npe rau nws, vim tias tus lej suab zoo li cov ntaub ntawv. Cov kab lus no yuav siv sij hawm nyuaj dua: 240 teev yog txoj kab dhau los, tsis yog kev cog lus, thiab tsib daim tshev txiav txim siab seb cov khoom puas tau txais nws txoj hauv kev rau hauv koj lub khw.
Xa rov qab los yog muab tso rau ntawm lub txee - kab yog kos tau. Khiav cov kab ke raws li kev txiav txim: ib qho kos rau ntawm lo lus ntawm daim ntawv thov, ib qho ntawm cov txheej txheem dhau los, ib qho ntawm tuab, ib qho ntawm cov ntaub ntawv, ib qho ntawm lawv tus kheej. Tsis muaj leej twg ntawm tsib xav tau chav kuaj. Ruihua Hardware ships tiv thaiv tib tsib daim tshev no, uas yog vim li cas lawv nyeem zoo li daim ntawv tshuaj ntsuam sau los ntawm lwm sab ntawm lub rooj ntev zaum.
Ua ntej, paub tias lub txee ua li cas. ASTM B117 tshuaj tsuag 5 feem pua sodium chloride pos huab ntawm 35 ° C, tsis tu ncua, ntawm qhov dai. TS EN ISO 9227 NSS piav qhia tib yam tshuaj tsw qab ntsev hauv cov lus sib txawv me ntsis. Kev xeem yog ib qho cuab yeej sib piv. Nws qhia koj li cas ib txheej coj tawm tsam lwm tus raws li kev tsim txom tsis tu ncua. Nws tsis qhia koj ib hnub.
Yog li coj lub stance thaum ntxov. Ib qho kev tsocai uas hloov 240 teev rau hauv 'xyoo ntawm lub neej' yog muag koj tus lej qhov kev xeem tsis tuaj yeem tsim. Ntxuav chemistry, txoj kev ntsev, abrasion thiab UV tag nrho qhib kev tawm tsam lub txee yeej tsis pom. Txais 240 teev raws li qhov pib koj tuav cov neeg muab khoom, batch tiv thaiv batch thiab txheej tiv thaiv txheej. Tsis lees paub txhua qhov kev txhais lus ntawm teev suav rau hauv daim ntawv qhia hnub. Qhov kev taw qhia ntawd ib leeg tua cov lus sib cav feem ntau ua ntej lawv pib.
Nyeem cov lus thov ntawm cov lus hais los ntawm lo lus. Cov lus nug uas tau lees paub muaj plaub yam: tus qauv lub npe (ASTM B117 lossis ISO 9227 NSS), lub sijhawm suav, cov txheej txheem dhau, thiab txheej txheej nrog nws cov tuab. 'Zinc-nickel 8-12 μm, tsis muaj xeb liab tom qab 240 h ib ASTM B117' yog ib daim ntawv thov. 'Salt spray tested' yog cov lus hais, thiab cov lus hais tsis tuaj yeem kuaj xyuas, rov ua dua, lossis sib cav nrog thaum sib koom ua ke quaj hauv lub hli kaum ib.
Teem txoj cai nyuaj: ib nqe lus hais tias tsis muaj tus qauv tsis yog tus nqi qis, nws yog qhov tsis lees paub. Xa RFQ rov qab ua ntej koj xa daim ntawv xaj khoom. Ib tsab ntawv teb kho nws; ib tug ua tsis tau tejyam retrofit tsis.
Cov teev suav txhais tsis muaj dab tsi txog thaum koj paub tias suav dab tsi ua tsis tiav. Dawb xeb yog zinc corrosion tawg rau ntawm qhov chaw. Nws zoo nkaus li tsis zoo thiab ua tsis raug mob; nws yog qhov xav tau thawj theem ntawm txhua qhov zinc system. Liab xeb yog lub hauv paus hlau corroding, thiab nws yog qhov uas txheej tau ua tsis tiav.
Yog li cov qauv uas koj lees txais yuav tsum yog xim liab-xeb-raws li thaum lub haum ua haujlwm sab nraum zoov. Rau zinc-nickel spec, kab yog 'tsis muaj xeb liab ntawm 240 teev'. Lub teeb nto tawg ntawm teev 240 ntawm ib qho passivated tsis yog qhov tsis siv neeg. Rau cov txheej txheem zinc plating, tus lej lej yog qhov sib txawv thiab ncaj ncees: zinc system nyob rau hauv 5-8 μm feem ntau tuav cov xeb dawb tawm li ntawm 96 teev, thiab xeb liab tuaj txog zoo ua ntej 240. Qhov ntawd yog ib txwm rau lub kaw lus, tsis yog lub hauv paus tsis lees paub - nws yog qhov tsim nyog los khaws cov khoom hauv tsev. Hom kev ua tsis tiav uas koj zam tau txiav txim siab qhov kev txiav txim, yog li sau cov txheej txheem ua ntej lub nkoj nkoj, tsis yog tom qab.
Sij hawm tsis muaj thickness yog ib nrab ntawm spec. Kev tso nyiaj ntawm 8-12 μm zinc-nickel nqa 240 teev hauv lub txee; deposits ntawm 5-8 μm zinc nqa roughly 96. Ib daim ntawv qhia hais tias thov 240 teev ntawm ib tug 3 μm deposit yog piav txog ib co lwm yam batch, los yog ib co lwm yam khoom.
Tshawb xyuas ntawm koj sab. Lub ntsuas hluav taws xob sib nqus nyeem nyeem cov pa roj carbon monoxide zoo txaus rau kev txiav txim siab nres, thiab XRF meter nyeem tsis tau txiav. Siv peb qhov kev nyeem ntawv ib feem: lub khob hliav qab lub rooj, hauv cov xov khiav, thiab lub shank. Sib piv qhov tsawg kawg nyeem ntawv tiv thaiv lub qhov rais tuab ntawm daim ntawv pov thawj. Hauv qab qhov tsawg kawg nkaus tau teev tseg, tsis lees txais cov batch txawm hais tias tsab ntawv ceeb toom hais tias - daim ntawv tshaj tawm tsuas yog ncaj ncees raws li nws qhov txuas mus rau qhov chaw nyob ntawm koj xub ntiag.
Ib qho kev tiv thaiv corrosion tsuas yog tiv thaiv koj yog tias nws muaj sia nyob tag nrho cov saw: daim duab callout hloov mus rau kev yuav khoom, daim ntawv xaj khoom mus rau cov khoom tsim khoom, cov khoom siv rau lub thawv ntawv, thiab lub thawv rau daim ntawv pov thawj batch. Hla ib qhov txuas thiab koj qhov kev tshuaj xyuas tuaj tsis muaj dab tsi los kuaj xyuas.
Ruihua Hardware cim cov plating spec ntawm lub thawv ntawv thiab teeb meem batch daim ntawv pov thawj ntawm kev thov, yog li cov lus hu zoo li 'Zn-Ni 8-12 μm, 240 h ib ASTM B117' tuaj txog sau rau txhua txheej ntawm cov khoom xa tuaj. Tuav koj cov neeg xa khoom mus rau tib txoj hlua. Ntawm qhov rov qab ua haujlwm lossis OEM txoj haujlwm uas xav tau kev taug qab, ib pawg tsis muaj daim ntawv pov thawj yog tuav, tsis yog qhov tsis lees paub thiab tsis lees txais - cov khoom tos kom txog thaum daim ntawv ntes. Khaws cov ntawv lo nrog cov thawv ntim khoom; ob txheej txheej txheej zoo ib yam tawm ntawm lub thawv, thiab qhov kev hloov pauv tom ntej yuav sib xyaw ua ke hauv ib hlis.
Qhov kev kuaj zaum kawg yuav siv sijhawm kaum feeb thiab pom feem ntau ntawm qhov tseem ceeb. Ua haujlwm los ntawm lub thawv qhib hauv qhov kev txiav txim no:
Xov tiv thaiv. Txhua threaded kawg nqa lub hau los yog ntsaws. Liab threads nyob rau hauv ib tug humid tuav khaws thawj lub paj ua ntej ib feem puas tau ntsia.
Xim thiab uniformity. Ob txheej txheej txheej tuaj tawm ib yam xim hlau nyiaj. Patchy grey, cloudy thaj ua rau thaj los yog hmoov zoo li deposits nyob rau hauv threads tsim nyog ib tug thib ob saib.
Tsis muaj liab nyob qhov twg. Xyuas cov rooj zaum lub khob hliav qab, lub bores thiab cov xov hauv paus rau cov xim liab. Ib feem liab yog ib qho piv txwv tswb rau tag nrho cov batch.
Kev pab them nqi rau qhov complex. Lub luj tshib thiab tees dai ntawm racks thaum plating yog li txhua lub khob hliav qab tau txais txawm tias tso nyiaj. Lub ntsej muag dull lub ntsej muag ntawm lub luj tshib hais tias kev npog yog nyias qhov uas nws tseem ceeb tshaj plaws.
Cov ntawv sau tsis raug. Lub thawv ntawv nyeem tau, plating spec legible, batch naj npawb tam sim no. Tsis muaj daim ntawv lo, tsis muaj traceability, tsis muaj ntawv pov thawj tom qab.
Yog hais tias tus spec npog cov khoom muaj zog xws li ferrules saum 1000 MPa tensile, kuj paub meej tias cov hydrogen de-embrittlement ci yog teev - 190 txog 200 ° C tom qab plating, ntawm ob qho tib si zinc thiab zinc-nickel kab.
