Q: Hom txheej txheej dab tsi yog dab tsi?
A: dog dig polyester (PE), Silicon-hloov polyester (PVDF), epoxy redoride (Ep), Acrylic Acid (AC), Silicone (Silicone (Silicone (Silicone (Silicone (Silicone (Silicone (Silicone)
Q: Dab tsi yog qhov sib txawv ntawm cov ntsev tshuaj txau corrosion corrosion tsis kam ntawm PVDF, Epoxy Resin, thiab PE Tsho Tsho?
A: PVDF \/ Fluorocarbon Cov Txheej Txheem Muaj cov qauv nyiaj fluorocarbon muaj cov qauv nyiaj siab, thiab tuaj yeem xeem dhau kev nkag mus ntau tshaj 1500 teev. Nws yog qhov haum rau cov dej hiav txwv ntug dej (xws li ntug dej hluav taws xob thiab cov vaj tse nres nkoj). Epoxy Resin: Thaum siv los ua tus tsim cov primer, nws muaj cov txheej txheem zoo rau cov txheej txheem, ua ib txheej "shielding txheej" los thaiv ntsev nkag. Nws yog feem ntau siv nyob rau hauv cov nkoj primers (kev ntsuam xyuas ntsev tuaj yeem ncav 2000 teev tom qab txuam topcoat).
PE Oating: cov molecular chain muaj cov pab pawg ester, uas tej zaum yuav hydrolyze tom qab siv sijhawm ntev nrog cov tshuaj ntsev. Nws tsuas yog haum rau hauv cov chaw ib puag ncig nrog cov tshuaj tsuag ntsev tsawg tsawg dua 100mg \/ m³.
Q: Dab tsi yog qhov sib txawv ntawm cov tshuaj corrosion tsis kam ntawm epoxy cob (EP), PVDF, thiab SMP tsho loj?
A: Epoxy Resin (EP): muaj cov pab pawg epoxy hauv cov molecule, uas tuaj yeem tawm tsam cov kua dej ntau nrog cov ph {}}}. Nws yog feem ntau siv nyob rau hauv phab ntsa sab hauv ntawm cov tso tsheb hlau luam yeeb tshuaj thiab dej phwj.
PVDF: nws corrosion tsis kam yog ze rau tias polytetrosraethylene (PTFE). Nws tuaj yeem tiv taus 90% concentrated sulfuric acid thiab 30% sodium hydrocide tov. Nws haum rau sab nrauv phab ntsa ntawm cov tshuaj tiv thaiv tshuaj lom neeg.
SMP txheej: cov nyiaj txiag silicon-oxygen tau txhim kho tshuaj lom neeg ruaj khov thiab muaj cov kua qaub zoo dua li PE. Nws yog qhov tsim nyog rau kev lag luam nroj tsuag (xws li ib ncig ntawm cov nroj tsuag hlau thiab cov nroj tsuag chiv).
Q: Dab tsi yog qhov sib txawv hauv huab cua tsis kam ntawm PVDF txheej, pe co coicone?
A: PVDF txheej: UV Kev Txom Nqi<5%, after 2000 hours of UV aging test (such as QUV standard), gloss retention rate >85%, xim hloov ΔEE<3, suitable for high UV areas (such as plateaus, tropical areas).
PE Oating: Hmoov tej zaum yuav tshwm sim tom qab 500 teev ntawm UV kev laus, thiab nws yuav tsum tau ua kom muaj caleces txhua {xyoo dhau los thaum siv hauv cov ntug hiav txwv.
Silicone txheej: qhov kub ua hauj siistance {}} degree ~ ecog degree ~ 250 degree ntawm qhov kub thiab txias scenes xws li lub teb chaws hluav taws thiab cav.
Q: Yuav ua li cas los xaiv corrosion-resistant txheej txheej hauv cov xwm txheej tshwj xeeb?
A: 1. Yuav tsum muaj kev lag luam khoom noj khoom haus: FDA daim ntawv pov thawj yog xav tau, thiab epoxy phenolic txheej, corrosion tsis kam thiab anti-microbial adhesion).
2. Marine Engineering: Zinc Pluas Ceeb Sab Nraud + Epoxy Intermedia xim + fluorocarbon topcoat peb-txheej ntau dua los yog sib npaug ntawm cov txheej txheem txhawb nqa ntau dua lossis sib luag rau 200μm.
3. New Zog Field: photovoltaic bracket siv Aluminium-zinc-zinc-zinc-zinc-zinc-zinc-zinc-zinc-perve}}} palvanized galvanized substrates).
