Paraphrased Version (nrog lub tuam txhab npe hloov kho rau GNEE qhov muaj feem tau)
Marine-qib aluminium alloys tau dhau los ua cov khoom siv zoo tshaj plaws rau decking thiab structural Cheebtsam ntawm cov hlab ntsha ua tsaug rau lawv lub peev xwm los tiv thaiv corrosion nyob rau hauv dej ntsev ib puag ncig thaum xa khoom tshwj xeeb lub zog - mus rau - hnyav ua haujlwm. Ntawm cov ntaub ntawv no, Marine 5083 thiab 5086 txhuas alloys nyob rau hauv H116 temper nrog ib tug checkered qauv raug lees paub raws li cov qauv kev lag luam. Lawv tau dav siv nyob rau hauv nkoj lawj panels, docks, offshore platforms, thiab lwm yam marine qauv xav tau kev ua tau zoo ib yam thiab vam khom.
Marine 5083/5086 H116 Checkered Aluminium Phaj yog dab tsi?
Alloy Designation: 5083, 5086 (Al{2}}Mg series)
Ob lub alloys muaj rau corrosion-resistant, tsis yog- tshav kub- kho tau txhuas- tsev neeg magnesium. Lawv muaj qhov sib npaug zoo heev ntawm lub zog, ductility, weldability, thiab tsis kam mus rau marine corrosion, ua rau lawv zoo tagnrho rau kev xav tau ib puag ncig marine.
Kub: H116
Lub H116 npau taws qhia tias muaj kev nyuaj siab - mob hnyav thiab ruaj khov tsim tshwj xeeb los txhim kho kev tiv thaiv kev ntxhov siab corrosion tawg thaum tuav lub zog txhua yam. Nws yog qhov kev npau taws txhais tau rau marine- qib txhuas daim hlau npaj rau kev raug mob hnyav.
Yam khoom: Checkered Plate
Cov phaj no yog kub- dov thiab tom qab ntawd tsim nrog pob zeb diamond tsa los yog checkered tread qauv. Cov ntaub ntawv zoo nkauj muab kev tiv thaiv zoo tshaj -kev ua haujlwm hauv pliaj, qhov tseem ceeb ntawm kev nyab xeeb rau cov chaw deck uas raug ntub dej, nplua dej hiav txwv ntawm cov nkoj lossis cov qauv hauv ntug dej hiav txwv.

Nta thiab Cov txiaj ntsig
Qhov zoo tshaj plaws Corrosion Resistance:Ob lub alloys muab kev tiv thaiv zoo heev tiv thaiv dej hiav txwv corrosion, nrog rau kev tiv thaiv pitting thiab kev ntxhov siab corrosion cracking - tseem ceeb heev rau kev siv dej hiav txwv.
Zoo heev Mechanical Strength:Lawv cov txiaj ntsig zoo thiab lub zog tensile pab tiv taus cov neeg kho tshuab loads thiab cuam tshuam rau lub nkoj decking.
Txhim kho Anti-Slip Deg:Cov qauv checkered muab kev ruaj ntseg tuav ntawm cov lawj ntub dej yam tsis muaj kev cuam tshuam ntev.
Superior Weldability:Ob lub alloys txhawb cov pob qij txha muaj zog thiab sib haum nrog MIG, TIG, thiab lwm yam kev siv vuam.
Lightweight Design:Qhov sib dua ntawm cov hlau tseem ceeb, ua rau txo cov hlab ntsha hnyav thiab txhim kho roj efficiency.
Thaum tshav kub kub thiab UV Durability:Ua kom ruaj khov ua haujlwm thoob plaws qhov kub thiab txias thiab tiv thaiv kev puas tsuaj los ntawm kev raug UV ntev ntev.
