1.Lub ntsiab lus xaus yog dab tsi?
Qhov zoo: Tus nqi qis dua, ntau yam xim xaiv, thiab zoo nkauj zoo nkauj.
Cov Kev Sib Tw Loj: Sab hauv ntawm lub tshuab ntxhua khaub ncaws yog qhov chaw huab cua uas muaj qhov kub thiab txias, cov av noo siab, thiab cov tshuaj lom neeg muaj zog (lub tsheb ntxuav kua, siv quav ciab, hlau hmoov tshem tawm), ua rau muaj kev sib tw loj heev rau kev nplaum, corrosion resistance, thiab sealing ntawm cov xim -coated coated.
Kev pom zoo dav dav: Siv ceev faj yog tias pob nyiaj siv tsawg heev, kev siv zaus tsawg heev (xws li, siv hauv tsev), thiab lub neej luv dua yog qhov tsim nyog. Rau kev lag luam, pej xeem, lossis kev siv tsheb ntau zaus, xim -coated yob tsis pom zoo ua cov khoom siv plhaub sab nraud.
2.Dab tsi yog cov kev pheej hmoo thiab cov teeb meem tseem ceeb?
Continuous Moisture thiab Condensation:
Sab hauv ntawm lub tshuab ntxhua khaub ncaws yog tas li raug cov av noo, ua rau cov hws muaj peev xwm nyob rau sab hauv ntawm lub qhov rooj sab nrauv. Sab nraub qaum ntawm lub pre-coated coil (feem ntau tsis muaj coated los yog tsuas yog ib txheej tiv thaiv nyias) yog tas li los ntawm noo noo, ua rau muaj kev pheej hmoo ntawm corrosion pib los ntawm sab hauv.
Tshuaj Corrosion:
Cov kua dej ntxuav tsheb, polishing waxes, lub log ntxuav, thiab lwm yam, feem ntau alkaline los yog muaj surfactants. Cov tshuaj no tsis tu ncua tuaj rau hauv kev sib cuag nrog lub kauj thiab tuaj yeem nkag mus rau hauv cov seams ntawm lub casing, ua kom cov txheej txheej aging thiab substrate corrosion.
Mechanical Damage thiab Sealing Challenges:
Lub casing sab nrauv yog yooj yim puas thaum lub sij hawm installation, kev thauj mus los, thiab tu. Thaum cov txheej txheej puas lawm, corrosion kis sai heev.
Tag nrho cov seams, ntsia hlau qhov, thiab qhov chaw txiav yuav tsum tau muab khi zoo kawg nkaus (siv cov nplaum nplaum, cov hlua khi, thiab tshwj xeeb los tiv thaiv- xim xim). Cov txheej txheem yuav tsum tsis tshua muaj siab precision; ib qho kev saib xyuas tuaj yeem dhau los ua qhov pib rau corrosion.
Structural Strength thiab Durability:
Piv rau cov hlau tsis muaj steel lossis engineering yas, ua ntej -coated coils (tshwj xeeb tshaj yog cov ntawv nyias nyias) muaj kev cuam tshuam tsis zoo thiab tag nrho cov rigidity, ua rau lawv yooj yim deformation raws li kev saib xyuas tsis tu ncua lossis kev cuam tshuam sab nraud.
3.Yog tias koj hais kom siv nws, "cov xwm txheej nruj" uas yuav tsum tau ua yog dab tsi?
Xaiv qhov siab tshaj -qib substrate thiab txheej:
Substrate: Yuav tsum siv xim-coated coils nrog aluminized zinc steel ntawv (55% aluminium-zinc alloy) ua lub substrate, vim nws corrosion kuj deb tshaj li ntawm cov ntawv zoo tib yam galvanized.
Txheej: Lub topcoat yuav tsum yog polyvinylidene fluoride (PVDF), uas muaj cov tshuaj tiv thaiv zoo tshaj plaws, thiab cov txheej thickness yuav tsum tau raws li tus qauv (topcoat Ntau tshaj los yog sib npaug rau 20μm). Cov primer tseem ceeb sib npaug; epoxy lossis polyester-raws li primers yuav tsum tau xaiv los txhim kho adhesion.
Exceptional tsim thiab txheej txheem:
Kev tsim qauv: Ib qho ua tiav cov kua dej thiab qhov cua yuav tsum tau tsim los tiv thaiv cov dej hauv txhua qhov chaw. Xav txog kev ntxiv cov tshuaj tiv thaiv -condensation txheej los yog txuas cov dej noo- nqus cov ntaub ntawv rau cov phab ntsa sab hauv.
Sealing: Tag nrho cov npoo txiav thiab qhov tho qhov yuav tsum tau muab khi nrog zinc -chromium txheej (Dacromet) lossis siab -kev ua haujlwm tiv thaiv- xim xim. Seams nruab nrab ntawm cov vaj huam sib luag yuav tsum tau muab khi nrog huab cua- silicone sealant.
Zam kom tsis txhob muaj qhov tiaj tus: Cov qauv tsim sab nrauv yuav tsum siv cov nqes hav kom ntau li ntau tau los tiv thaiv kom ntev li - cov dej sib xyaw rau saum npoo.
Kev siv nruj thiab kev saib xyuas yuav tsum tau ua:
Haum rau sab hauv tsev lossis los nag- thaj chaw nyob; zam lub hnub ncaj qha thiab los nag.
Siv cov tshuaj ntxuav tsheb nruab nrab lossis me me.
Tshawb xyuas tsis tu ncua thiab kho cov khawb me me tam sim ntawd.
4.Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev siv cov ntaub ntawv stainless hlau?
Qhov zoo: Tsis tshua muaj corrosion resistant, siab zog, txij nkawm-dawb, lub neej ntev heev, kev ua haujlwm zoo.
Disadvantages: tus nqi siab tshaj, txwv xim xaiv (feem ntau yog thawj xim), nyuaj rau txheej txheem.
5.Dab tsi yog cov ntsiab lus thiab cov lus qhia?
Rau kev lag luam peev lossis siab - zaus siv cov xwm txheej: ncaj qha xaiv stainless hlau (xws li 304 stainless hlau) lossis siab - fiberglass zoo. Txawm hais tias qhov kev nqis peev thawj zaug yog siab dua, nyob rau lub sijhawm ntev, lawv qhov tsis ua haujlwm tsawg kawg nkaus, nyob ze -zero tu nqi, thiab ultra- lub neej kev pab cuam ntev ua rau tus nqi qis dua ntawm cov tswv cuab thiab ntau tus kws tshaj lij thiab cov khoom lag luam txhim khu kev qha.
Yog tias cov peev nyiaj tsawg kawg nkaus thiab qhov chaw ua haujlwm tsis zoo: muab tag nrho cov saum toj no "xav tau cov xwm txheej" tau ua tiav, qhov tshwj xeeb tshaj plaws aluminium -zinc coated PVDF coils tuaj yeem xaiv, thiab kev tsim thiab kev kho sealing yuav tsum tau ua haujlwm los ntawm cov chaw tsim khoom. Txawm li cas los xij, npaj siab tias nws txoj kev ua neej zoo yuav luv dua li cov hlau tsis muaj steel thiab fiberglass.
