Hauv kev tswj cov tsheb pov tseg (xws li cov tsheb thauj khoom khib nyiab, cov tsheb thauj khoom khib nyiab, thiab cov tsheb thauj khoom khib nyiab) nrog rau cov cav ntoo hauv hiav txwv (xws li cov tshuab npog npog, ramps, windlasses, thiab steering gears), hydraulic cylinders ua haujlwm nyob rau hauv ib puag ncig hnyav dua li kev lag luam lossis kev tsim kho tshuab. Lawv raug cuam tshuam los ntawm kev sib xyaw ua ke ntawm cov av noo siab, tshuaj tsuag ntsev (cov cheeb tsam hauv hiav txwv), cov kua dej corrosive (cov ntaub ntawv pov tseg, cov tshuaj ntxuav tu, dej phwj), thiab qhov kub thiab txias. Ordinary carbon steel cylinders, txawm tias nrog cov xim pleev xim, ua tsis tau sai vim yog khawb, xeb nkag, thiab pitting, ua rau to, tsis txaus thrust, thiab cov khoom siv downtime.
Tsim los ntawm 2008,Yishui Zhongxin Machinery Co., Ltd. (Zhongxin)tau dhau los ua tus neeg muab khoom siv hydraulic zoo rau ntau lub tuam txhab loj hauv Australia, Tebchaws Asmeskas, Canada, Poland, Brazil, thiab lwm lub tebchaws. Hais txog cov kev xav tau tshwj xeeb ntawm cov khoom pov tseg thiab cov dej hiav txwv, Zhongxin qhia txog"Corrosion-Resistant Telescopic Lub tog raj kheej - Nickel{1}}Plated."Tsim kom muaj qhov zoo ntawm lub tog raj kheej telescopic (chaw-txuag installation, ntev stroke), cov khoom no undergoeselectroless npib tsib xee platingntawm lub thoob, piston pas nrig, thiab cov khoom tseem ceeb. This produces a dense, uniform, high-hardness, and highly corrosion-resistant nickel-phosphorus alloy coating, enabling reliable long-term operation in aggressive media such aspov tseg pov tseg, dej hiav txwv, thiab cov kua qaub / alkaline ntxuav.
1. Cov Khoom Tom Qab: Vim Li Cas Cov Khaub Ncaws & Marine Lub tog raj kheej xav tau kev tiv thaiv tshwj xeeb?
Corrosion Sources nyob rau hauv cov ntaub ntawv pov tseg
Landfill Leachate: Muaj ntau cov organic acids, ammonia nitrogen, chlorides, thiab ntau yam microbial metabolites, nrog pH tus nqi qis li 3.5-5.5, tsis tshua muaj corrosive rau cov hlau zoo tib yam.
Cov tshuaj ntxuav tes: Oxidizing tshuaj xws li sodium hypochlorite thiab hydrogen peroxide siv rau kev tua kab mob thiab deodorization.
High Humidity & Temperature Fluctuations: Cov chaw nres tsheb pov tseg thiab cov tsheb hauv qab feem ntau ntub thiab av nkos; Thaum cov txheej txheej puas lawm, lub hauv paus hlau rusts sai heev.
Corrosion Sources hauv Marine Applications
Ntsev Txau & Dej hiav txwv: Chloride concentrations txog 19,000 ppm, muaj zog pitting corrosion agent.
Marine Atmosphere: Tus txheeb ze humidity feem ntau tshaj 80%, nrog ntsev particle deposition.
Marine Roj & Tshuaj: Cov roj spilled, roj hydraulic, thiab deck tu neeg ua hauj lwm.
Cov kev txwv ntawm cov kev daws teeb meem
Xim Txheej: Tsis yooj yim; yooj yim scraped tawm thaum lub sij hawm reciprocating zawv zawg zog ntawm telescopic cylinder seem.
Hard Chrome Plating: Siab hardness tab sis muaj micro- tawg (micro-kab network). Nyob rau hauv ib puag ncig ntsev tsuag, rusting pib los ntawm cov kab nrib pleb. Tsis tas li ntawd, cov txheej txheem hexavalent chromium muaj kev ua tsis zoo ib puag ncig.
Stainless hlau: Tus nqi siab (tshwj xeeb tshaj yog rau cov loj -inch multi-stage cylinders), thiab qee qib tseem tuaj yeem raug kev txom nyem pitting corrosion hauv ib puag ncig tshwj xeeb.
Zhongxin tus npib tsib xee{0}}plated telescopic lub tog raj kheejtshwj xeeb yog tsim los ua kev sib npaug rau cov ntsiab lus mob no.
2. Cov yam ntxwv tseem ceeb: Qhov Zoo Tshaj Plaws ntawm Nickel- Phosphorus Txheej
2.1 Zoo heev Corrosion Resistance - Nyob deb tshaj cov tsoos tsho hauv kev tshuaj ntsuam ntsev
Zhongxin ua haujlwmelectroless nickel plating (siab-phosphorus formulation, 10-12% P cov ntsiab lus). Tsis zoo li electroplating, electroless plating yuav tsum tsis muaj lwm yam tam sim no; nws deposits atsis yog- ntxeem tau, sib xwsnpib tsib xee-phosphorus alloy txheej ntawm cov tshuaj tiv thaiv autocatalytic.
Ntsej Tsuag Test Performance: Nrog lub thickness ntawm 25-50μm, nws ua tiav500-1000+ teev cov tshuaj ntsev nruab nrab (NSS) kuaj tsis muaj xeb liab, piv rau 96-200 teev rau cov tawv chrome thiab tsuas yog 100-300 teev rau xim (nyob ntawm qhov khawb).
Acid / Alkali / Seawater Resistance: High-phosphorus electroless npib tsib xee yog qhov ruaj khov nyob rau hauv pH 4-9 ntau yam, nrog rau cov dej hiav txwv zoo heev, dilute sulfuric acid, sodium hydroxide, thiab cov dej khib nyiab pov tseg.
Kev Tiv Thaiv Electrochemical: Qhov tsis tshua muaj porosity ntawm cov txheej zoo cais cov substrate (45 # steel los yog 27SiMn alloy steel) los ntawm corrosive media.
2.2 High Hardness & Wear Resistance - Withstands Reciprocating Sliding Friction
Thaum lub sijhawm ua haujlwm, telescopic cylinders muaj kev sib txhuam zawv zawg kev sib txhuam ntawm cov theem thiab nruab nrab ntawm tus pas nrig piston thiab cov lus qhia bushings.
Txheej Hardness: Tom qab kev kho cua sov, electroless nickel txheej ncav cuagHV 850-1000 (kwv yees. HRC 62-68), piv rau lossis txawm tias nyuaj chrome (HV 800-1000).
Tus kheej -Lubricating Property: Cov npib tsib xee-phosphorus alloy muaj qhov sib txhuam qis qis, txo cov nplaum nplaum thiab fretting hnav thaum ua ke nrog cov yeeb yaj kiab roj.
Zoo Ductility: Muab piv rau cov tawv chrome, electroless npib tsib xee muaj kev ntxhov siab sab hauv thiab tsis tshua muaj kev cuam tshuam rau hauv kev sib cuag siab.
2.3 Uniform Coating Coverage - Tsis muaj cov kab tuag ntawm cov duab nyuaj
Telescopic cylinders muaj cov geometries nyuaj nrog rau cov roj hla, xov, grooves, thiab cov kauj ruam. Electroplated nyuaj chrome raug kev txom nyem los ntawm "nthuav lub zog" cov teeb meem, tawm hauv qhov chaw recessed heev nyias los yog unplated. Electroless npib tsib xee yograws cai- Txhua qhov chaw nyob rau hauv kev sib cuag nrog cov tshuaj tau txais ib qho tuab tuab (hauv ± 10%), kom ntseeg tau tias threaded qhov, sab hauv phab ntsa, thiab roj chaw nres nkoj npoo yog sib npaug tiv thaiv.
2.4 Qhov cuam tshuam tsawg kawg nkaus rau lub zog ntawm lub zog ntawm lub substrate - Haum rau siab -Lub tog raj kheej Telescopic
Telescopic cylinders feem ntau ua haujlwm ntawm kev ua haujlwm siab ntawm 20-35 MPa, ua rau qaug zog ntawm cov khoom siv. Electroless npib tsib xee plating tshwm sim ntawm qhov kub thiab txias (feem ntau 85-95 degree) thiab, thaum tswj kom zoo nrog kev kho tom qab hydrogen de-embedding, nthuav tawm me ntsis hydrogen embrittlement txaus ntshai. Piv nrog rau cov tawv chrome, nws muaj qhov cuam tshuam tsis zoo rau substrate qaug zog.
2.5 Kev Ua Raws Li Ib Cheeb Tsam - Ua Tau Raws Li Cov Cai Niaj Hnub No
Electroless npib tsib xee plating tsis siv hexavalent chromium (Cr⁶⁺), ib yam khoom txwv los ntawm ib puag ncig kev cai xws li RoHS thiab REACH. Rau cov khoom pov tseg lossis cov khoom siv hauv hiav txwv xa tawm mus rau EU lossis North American kev lag luam, xaiv cov npib tsib xee-plated cylinders pab ua kom tiav lub tshuab dhau ib puag ncig kev tshuaj xyuas.
