Thaum xaivxim-coated aluminium coils (pre-coated/xim-coated)rau qhov project tshiab, koj puas tau ntsib qhov teeb meem no: cov neeg muab khoom xa tuaj rau koj ntau pawg (PE, HDPE, PVDF, FEVE) thiab thickness tsis, tag nrho seemingly zoo sib xws, tab sis nrog cov nqi sib txawv los ntawm ib qho ntawm ob.
Xaiv qhov kev xaiv pheej yig dua yuav ua rau muaj kev puas tsuaj los yog bubbling hauv ob lossis peb xyoos, ua rau cov neeg thov kev pab; xaiv qhov kev xaiv kim tshaj qhov kev pheej hmoo tshaj cov peev nyiaj.
Qhov no yog qhov tseeb qhov teeb meem peb xav daws hnub no. Raws li ib pab neeg nrog 32 xyoo dhau los hauv kev lag luam no, peb yuav tsis qhia koj cov ntaub ntawv kuaj mob; Hloov chaw, peb yuav xa ncaj qha cov kev paub dhau los ntawm ntau pua txoj haujlwm ua tiav thiab ua tsis tiav thoob ntiaj teb.
I. Tsis txhob tsom rau xim ua ntej; tsom rau ntawm aluminium nws tus kheej.
Txheej teeb meem qee zaum qia tsis yog los ntawm cov xim, tab sis los ntawm aluminium substrate. Nov yog ib zaj lus qhia ntau tus pib kawm.
Alloy qib xaiv: Rau feem ntau architectural thiab hniav xim -coated aluminium coils, AA3003 los yog AA3004 txhuas alloys yog nyiam. Lawv muaj ib tug nruab nrab manganese cov ntsiab lus thiab zoo zog thiab formability. Yog tias koj xav tau dabtsi yog khoov lossis dov, AA3003 txaus; Yog tias koj xav tau kev sib sib zog nqus stamping lossis riveting, AA3004 zoo dua.
Peb qhov kev paub dhau los yog tias cov neeg siv khoom Australian ib zaug tau yuav ib pawg ntawm cov khoom pheej yig txhuas coils rau cov vuas vov tsev, tsuas yog pom cov kab nrib pleb ntawm cov quav. Kev tshuaj xyuas tau qhia tias cov substrate siv yog qis dua -lub zog AA1100. Txawm hais tias AA1100 muaj kev tiv thaiv corrosion zoo, nws lub zog txhua yam tsuas yog tsis txaus rau cov hlau vov tsev uas xav tau kev sib txuas sib txuas. Yog li ntawd, thawj txoj cai ntawm tus ntiv tes xoo: rau kev thauj khoom -cov kabmob, xaiv AA3003 lossis AA3004.
Aluminium Coil Thickness Xaiv:
- 0.2mm-0.3mm: Rau cov paib sab hauv tsev (cov ntawv kos npe txhuas), cov ntawv teev npe, thiab daim ntawv thov kho kom zoo nkauj ib zaug nkaus xwb.
- 0.4mm-0.6mm: Rau sab hauv qab nthab, ntaub thaiv phab ntsa panels (aluminium composite panels), kab hlau rhuav, thiab lwm yam., nyob rau hauv cov nqi-zoo.
- 0.7mm-1.0mm: Lub ntsiab thickness rau lub tsev sab nrauv phab ntsa, ru tsev, awnings, thiab downpipes. Qhov no yog peb lub siab tshaj plaws-ntim specification nyob rau hauv European lub tsev cov ntaub ntawv ua lag luam.
- 1.2mm thiab saum toj no: Cov ntaub thaiv phab ntsa tshwj xeeb thiab siab -end decorations.
Thov nco ntsoov tias thaum cov neeg muag khoom hais tias "0.7mm tuab," lawv puas txhais tau tias lub thickness ntawm txhuas substrate los yog tag nrho cov thickness nrog rau cov txheej? Qhov no yog qhov sib txawv ntawm tus nqi yuav dag; nco ntsoov qhia meej qhov no hauv daim ntawv cog lus.
II. Txheej Txheej Txheej: Kev Lag Luam -tawm ntawm Tus Nqi thiab Lub Neej
Nyob rau hauv seem no, peb yuav tsis nco tsis tau; peb yuav siv cov xwm txheej los qhia peb cov ntsiab lus.
Scenario 1: Kuv tsuas yog ua cov phab ntsa kho kom zoo nkauj sab hauv, thiab kuv cov peev nyiaj nruj heev.
Teb: Ordinary polyester (PE) txheej.
Qhov no yog tus nqi qis tshaj - kev xaiv. Nyob sab hauv tsev, tsis muaj UV hluav taws xob, thiab qhov ci thiab xim ntawm PE txheej tuaj yeem kav ntev dua 15 xyoos. Txawm li cas los xij, tsis txhob nthuav tawm cov panels rau hnub ci. Ordinary PE yuav pom pom ploj tom qab li 3 xyoos ntawm kev tawm sab nraum zoov. Peb muab ib pawg ntawm PE aluminium coils rau sab hauv partitions mus rau lub khw muag khoom hauv South Africa. Kaum xyoo tom qab, thaum lub sij hawm kho dua tshiab, sab hauv tseem zoo li tshiab, tab sis ob peb lub vaj huam sib luag yuam kev rau ntawm lub qhov rooj nkag rau tib lub sij hawm hmoov tom qab tsuas yog ob xyoos.
Scenario 2: Kuv yuav tsum ua lub Hoobkas sab nrauv phab ntsa thiab lub ru tsev warehouse, xav tau huab cua tsis kam tab sis raug nqi - rhiab heev.
Teb: High -kev ua tau zoo polyester (HDPE / Super Polyester) txheej.
Qhov no yog qhov tiag "tau nyiaj cheeb tsam." HDPE's UV tiv thaiv thiab tiv thaiv- muaj peev xwm ua hmoov av ntau dua li cov PE zoo tib yam, muab 8-10 xyoo xim warranty nyob rau hauv feem ntau tsis yog- huab cua huab cua. Nws tus nqi yog kwv yees li 40% qis dua PVDF, ua rau nws tus qauv rau lub tsev lub hnab ntawv hauv North America thiab Australia. Ib lo lus qhia: Yog tias koj tab tom twv rau qhov chaw ua haujlwm nruab nrab ntawm qhov chaw ua haujlwm thiab koj cov neeg sib tw siv HDPE, siv PE li niaj zaus yog ib daim ntawv qhia rau kev puas tsuaj; siv PVDF yuav ua rau cov nqi siab heev thiab cov ntawv cog lus poob. HDPE ntaus qhov sib npaug zoo meej.
Scenario 3: Kuv tej yaam num muaj xws li seaside villas, siab - nce landmarks, thiab tshav dav hlau, yuav tsum tsis txhob fading rau ntau tshaj 20 xyoo.
Teb: PVDF fluorocarbon xim (KYNAR® lossis sib npaug).
Qhov no yog qhov kawg ntawm txheej txheej technology. PVDF coatings nyob twj ywm unmatched nyob rau hauv huab cua tsis kam, tshuaj corrosion kuj, thiab chalking kuj. Nyob rau hauv lub hnub ci ntsa iab ntawm Florida, cov xuab zeb ntawm Dubai, thiab corrosive hiav txwv ntsev ntawm cov teb chaws Asia, tsuas yog PVDF tuaj yeem lav qhov zoo nkauj tom qab 20 xyoo.
Peb ib zaug tau txais kev pabcuam beachfront resort project nyob rau hauv lub tebchaws Caribbean lub teb chaws uas tus tswv tau teev PVDF txhuas coils rau kab hlau rhuav phab ntsa. Cov xim zoo nkauj lub neej yuav tsum tau halved nyob rau hauv cov huab cua kub thiab ntsev tsuag muaj. Txuag nyiaj rau qhov no yuav yog kev puas tsuaj.
Scenario 4: Kuv xav tau ultra- siab gloss, daim iav-zoo li cov nyhuv, thiab sab saum toj- huab cua tsis kam.
Teb: FEVE fluorocarbon txheej (LUMIFLON®).
FEVE yog lwm tus tswv cuab muaj zog ntawm tsev neeg fluorocarbon, ua tiav ntau dua 80% siab gloss thiab kho ntawm chav tsev kub. Nws tau txais kev pom zoo hauv cov haujlwm siab - kawg hauv Nyiv thiab Europe. Thaum koj xav tau kev ua haujlwm ntev ntawm PVDF thiab lub zog, siab -gloss tiav ntawm cov xim tsheb, FEVE yog tib txoj kev daws teeb meem.
Cov lus txiav txim ceev ceev rau txheej xaiv:
III. Nthuav Qhia Tsis Muaj Ib Tus Hais
1. Zaj duab xis Thickness ≠ Huab cua Resistance
Thicker xim tsis tas txhais tau tias muaj zog dua. Cov txheej txheem zaj duab xis tuab rau PVDF txheej yog 25-30μm, tab sis txawm tias 40μm txheej ntawm PE zoo tib yam yuav tsis zoo li qub. Durability nyob ntawm cov resin nws tus kheej thiab cov formulation. Yog li ntawd, nug "peb xyoo warranty" yog qhov ncaj tshaj qhov nug "peb cov xim tuab npaum li cas."
2. Tsis txhob hla lub nraub qaum
Ntau tus neeg muas zaub xav tias ntev npaum li lub hauv ntej zoo, qhov pheej yig tshaj txheej rov qab yog qhov zoo. Qhov no yog qhov yuam kev loj. Tom qab aluminium coil yog tsim, lub nraub qaum kuj raug rau huab cua, noo noo, thiab condensation. Peb pom zoo kom hais tias rau sab nraum zoov aluminium coils, lub nraub qaum txheej yuav tsum tsawg kawg yog siv primer thiab rov qab txheej ntawm tib txheej txheej. Tsis tas li ntawd, tsis muaj teeb meem zoo npaum li cas ntawm cov txheej txheem tiv thaiv nyob rau hauv pem hauv ntej, noo noo yuav corrode los ntawm sab nraum qab, ua rau lub txheej rau blister thiab tev.
3. Cov yeeb yaj kiab tiv thaiv yog kab kawg ntawm kev tiv thaiv
Thoob plaws hauv kev thauj mus los, uncoiling, khoov, thiab kev teeb tsa, cov yeeb yaj kiab tiv thaiv yog qhov ntsuas tsis pom kev nyab xeeb. Yog tias koj npaj yuav siv PVC zaj duab xis rau kev kos duab sib sib zog nqus, thov qhia rau peb ua ntej kom peb tuaj yeem muab cov yeeb yaj kiab tiv thaiv tsim nyog uas tsim nyog thiab tsis muaj cov nplaum nplaum. Ib tus neeg siv khoom Dutch ib zaug tau ntsib cov nplaum tsis ua haujlwm thiab cov qhab nia vim siv cov yeeb yaj kiab tiv thaiv zoo tib yam rau kev kos duab sib sib zog nqus, ua rau cov khoom seem ntawm tag nrho cov khoom. Peb tau pab koj zam qhov teeb meem no.
IV. Txheeb xyuas 5 cov ntsiab lus no nrog tus neeg muag khoom ua ntej yuav khoom
Nov yog ib daim ntawv uas peb tau distilled los ntawm countless xaj; koj tuaj yeem siv nws ncaj qha:
1. Dab tsi yog qib aluminium alloy thiab qhov tseeb thickness? (Nws puas yog AA3003 lossis lwm yam? Puas yog lub thickness ntawm cov khoom siv hauv paus lossis tag nrho cov tuab?)
2. Dab tsi yog hom thiab hom resin yog txheej txheej txheej? (PPG? Akzo? Valspar? Puas yog PE / HDPE / PVDF / FEVE?)
3. Dab tsi yog qhov tuab ntawm cov xim pleev xim rau pem hauv ntej thiab txheej txheej ntawm sab nraub qaum? (Puas muaj txheej txheej rov qab? Nws yog dab tsi?)
4. Koj puas muaj cov lus qhia tshwj xeeb rau kuv cov txheej txheem ua haujlwm (bending, stamping, lamination)? (Koj puas tuaj yeem muab cov qauv rau kev sim?)
5. Yog tias nws yog siv rau sab nraum zoov, lub sijhawm lav rau xim thiab gloss yog dab tsi? (Lub warranty npog chalking, cracking, fading, thiab lwm yam.)
Peb txoj hauv kev sib txawv: Thaum koj xa ib qhov kev xav tau rau peb, peb tsis teb nrog cov lus hais, tab sis nrog daim ntawv pov thawj kev paub uas muaj tag nrho cov ntsiab lus hais saum toj no. Vim tias peb tau nkag siab txog kaum xyoo dhau los uas xaiv cov txheej txheej tsis raug tuaj yeem ua rau tus neeg siv khoom ntau dua li kev txiav txim; nws tuaj yeem raug nqi rau lawv lub koob npe nrov ntawm kev lag luam tag nrho.
[Xa cov duab kos lossis cov lus piav qhia ntawm koj qhov yuav tsum tau ua], thiab cia peb leverage peb tshaj peb caug xyoo ntawm lub ntiaj teb no project kev paub nrhiav koj ib tug meej txheej tov tsis inflating nqi.
