Dab tsi yog Qhov Kev Cia Siab Lifespan Ntawm Aluminium Alloy Qhov Rooj?

Nyob rau hauv lub tshav pob ntawm niaj hnub architecture thiab lub tsev tsim, kev xaiv ntawm lub qhov rooj thiab qhov rais cov ntaub ntawv yog ib txwm muaj kev txhawj xeeb. Rau cov tswv tsev, architects, thiab cov neeg tsim vaj tsev, cov lus nug nquag nug yog: dab tsi yog qhov kev cia siab ntawm aluminium alloy qhov rooj?

Raws li kev sim ntau cov ntaub ntawv, cov ntaub ntawv qhia txog kev ua tau zoo ntawm cov ntaub ntawv, thiab kev txheeb xyuas tus nqi, SGL xaus lus tias qhov kev cia siab ntawm lub neej ntawm siab - zoo aluminium alloy qhov rooj nyob rau hauv cov qauv ib puag ncig yog feem ntau ntawm 30 thiab 50 xyoo. With fluorocarbon coating surface treatment and rigorous maintenance, the lifespan can be extended to over 60 years, far exceeding the lifespan of uPVC (usually 20-35 years) and traditional wood (usually 20-30 years).

Lub neej ntev ntawm aluminium alloy qhov rooj feem ntau yog txiav txim siab los ntawm qhov zoo ntawm aluminium alloy substrate, qib ntawm kev kho deg technology, kev laus tus nqi ntawm thermal so strips, lub neej txhua yam lub neej ntawm cov khoom siv kho vajtse, thiab cov txheej txheem installation.

Raws li tus kws tshaj lij hauv cov khoom siv hauv tsev thiab kev ua haujlwm sib sib zog nqus nrog ze li 20 xyoo ntawm kev paub, SGL tshawb xyuas txhua yam uas txiav txim siab txog lub neej ntawm aluminium alloy qhov rooj. Peb yuav tsis tsuas tsom rau cov lej xwb tab sis kuj tshawb txog cov hauv paus ntsiab lus, muab cov ncauj lus qhia ntxaws ntxaws rau tag nrho lub neej ntawm aluminium alloy qhov rooj. Daim ntawv tshaj tawm no tsis yog tsuas yog los teb "nws yuav kav ntev npaum li cas," tab sis kuj yog los teb "yuav ua li cas kom nws kav ntev dua."

1. Kev soj ntsuam ntawm Aluminium Alloy Qhov Rooj Profiles

 

 

Lub neej ntev ntawm aluminium alloy qhov rooj yog vim muaj cov khoom zoo ntawm txhuas. Txawm li cas los xij, tsis yog txhua qhov txhuas siv hauv qhov rooj thiab qhov rais yog tib yam. Lub tsev qhov rooj thiab qhov rais kev lag luam feem ntau siv 60 series txhuas-magnesium-silicon alloys. Thaum xaiv cov khoom siv aluminium, cov qauv thiab cov lus qhia tshwj xeeb yog qhov tseem ceeb hauv kev txiav txim siab qhov kev ua tau zoo thiab tus nqi ntawm lub qhov rooj thiab qhov rais. Cias muab, tus qauv tsuas yog nyob ntawm ob qhov chaw: aluminium alloy hom (xws li 6063, 6060) thiab lub xeev kev kho cua sov (xws li T5, T6, T66).

 

1.1 6063-T5, 6063-T6, 6060-T66

6063-T5yog lub ntsiab kev xaiv rau architectural qhov rooj thiab qhov rais, tshwj xeeb tshaj yog dav siv nyob rau hauv lub teb chaws tus qauv. Cov hlau no feem ntau muaj 0.45% -0.9% magnesium thiab 0.2% -0.6% silicon. Nws muaj kev ua tau zoo extrusion thiab kev kho deg, haum rau kev ua cov ntoo khaub lig- ntu, xws li thermal so aluminium qhov rooj thiab qhov rais. Nws muaj nruab nrab hardness thiab lub zog, zoo ductility, thiab tsis yooj yim rau tawg thaum lub sij hawm ua . 6063-T5 muaj corrosion kuj heev. Tsis zoo li aerospace-qib txhuas, thaum 6063-T5 raug rau huab cua, qhov ntom ntom, tawv, thiab pob tshab aluminium oxide zaj duab xis sai sai rau ntawm nws qhov chaw. Cov yeeb yaj kiab no muaj peev xwm "kho nws tus kheej" - yog tias qhov chaw raug khawb, oxide zaj duab xis tshiab yuav sai sai, tiv thaiv corrosion ntxiv ntawm cov hlau.

 

6063-T6: Siab zog thiab lub zog ntau dua T5, haum rau cov ntaub thaiv phab ntsa loj lossis cov chav hnub ci uas yuav tsum tau muaj zog dua. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias nws cov hardness siab tuaj yeem ua rau nws tawg thaum qee cov kauj ruam ua haujlwm (xws li ntxig cov thermal so strips).

 

6060-T66:Nws yog ntau dua nyob rau hauv cov qauv European. Nws cov ntsiab lus magnesium thiab silicon txawv ntawm 6063, nrog cov ntsiab lus silicon ntawm 0.5%-0.9% thiab magnesium ntsiab lus ntawm 0.35%-0.6%. Nws muaj zog dua tag nrho thiab hardness, thiab tseem hu ua "aerospace qib." Nws yog qhov tshwj xeeb tshaj yog tsim rau cov ntawv thov uas xav tau lub zog siab thiab cua tsis kam, xws li hauv pem teb - rau-qab nthab qhov rais lossis chav hnub ci hauv cov tsev siab. Nws yog qhov tsim nyog siv rau hauv cov ntug dej hiav txwv thiab cov av noo, tab sis nws cov nqi yog siab tshaj.

 

Ntau qhov qis- kawg qhov rais thiab qhov rooj, txhawm rau txo cov nqi, tuaj yeem siv cov khoom siv txhuas uas tsis tau ua raws li kev tswj hwm nruj ntawm cov ntsiab lus impurity thaum lub sij hawm remelting. Cov impurities (xws li cov ntsiab lus hlau ntau dhau) tuaj yeem cuam tshuam qhov txuas ntxiv ntawm cov yeeb yaj kiab oxide, ua rau pitting corrosion nyob rau hauv cov khoom siv txhuas hauv ob peb xyoos hauv cov ntug dej hiav txwv. Yog li ntawd, xav txog ob qho tib si tus nqi thiab kev ua tau zoo, xaiv 6063-T5 alloy nrog nruj tswj impurities yog qhov kev daws teeb meem zoo tshaj plaws los xyuas kom meej lub neej ntev ntawm aluminium alloy qhov rooj thiab qhov rais.

 

 

2. Kev kho deg

 

 

 

Cov txheej txheem kev kho saum npoo rau txhuas profile feem ntau suav nrog anodizing, electrophoretic txheej, hmoov txheej, fluorocarbon spraying, thiab ceramic electrophoretic txheej. Txhua txoj kev kho mob muaj nws tus kheej zoo.

2.1 Hmoov Txheej

Txoj kev no siv cov hmoov coatings thiab siv electrostatic txau. Siv rab phom txhuam txhuam, cov hmoov hmoov tau muab cov nqi zoo nyob rau hauv kev cuam tshuam ntawm huab cua nrawm, thiab tom qab ntawd los rau hauv kev sib cuag nrog cov ntaub ntawv tsis zoo, ua rau electrostatic adsorption, ua raws li siab - kub curing.

• Lub neej kev cia siab: Ntau tshaj 20 xyoo.
• Kev siv tau: Haum rau cov qhov rooj sab hauv lossis thaj chaw uas tsis tshua muaj hluav taws xob ultraviolet.
• Muaj peev xwm txaus ntshai: Yog tias muaj kev puas tsuaj me me rau cov txheej txheej txheej (xws li khawb thaum lub sijhawm teeb tsa), ntsev thiab noo noo tuaj yeem nkag mus rau hauv qab txheej txheej, sib kis thoob plaws txhuas qhov chaw zoo li kab, tsim cov hlwv filamentous thiab cov cim corrosion. Qhov no tuaj yeem ua rau loj - nplai tev ntawm txheej.

2.2 Fluorocarbon Txau

Txoj kev no siv cov tshuaj polyvinylidene fluoride (PVDF) xim txheej rau saum npoo ntawm aluminium alloy substrate los ntawm kev ua electrostatic. Nws muaj qhov ntev - xim khaws cia ntev, tiv thaiv- kev laus, kev tiv thaiv corrosion, thiab tsis kam rau huab cua phem, ua rau nws muaj kev kub siab - kawg txheej txheej txheej.

• Cia siab tias yuav muaj sia nyob: PVDF coated aluminium qhov rooj tuaj yeem tswj tau lawv cov xim thiab tiv thaiv chalking rau 30-40 xyoo.

 

2.3 Anodizing

Extruded aluminium alloy profiles muaj zog nto corrosion kuj. Anodizing yog tsim nyog los kho qhov saum npoo ntawm aluminium profiles kom lawv cov corrosion kuj, hnav tsis kam, thiab zoo nkauj tsos. Under certain process conditions, the pre-treated profile undergoes anodizing on its surface, forming a dense, porous, and highly adsorptive Al2O3 film layer.

• Kev cia siab lifespan: Txoj kev xav, tib lub neej raws li lub tsev (50-80 xyoo). Qhov no yog vim tsis muaj "txheej txheem" ​​los tev tawm. Cov oxide zaj duab xis no muaj qhov nyuaj siab heev (Mohs hardness 9, thib ob tsuas yog pob zeb diamond) thiab hnav zoo heev.

Niaj hnub nimno aluminium alloy qhov rooj yuav luag tag nrho siv "thermal so" thev naus laus zis. Cov cuab yeej siv no suav nrog kev sib txuas cov thermal rwb thaiv tsev ntawm cov txheej sab hauv thiab sab nrauv ntawm txhuas kom cuam tshuam cov cua sov hloov. Qhov rwb thaiv tsev no cuam tshuam ncaj qha rau lub neej ntawm tag nrho lub qhov rooj.

Tom ntej: 3.1 Polyamide 66 (PA66)

 

Cov khoom zoo tshaj plaws hauv ntiaj teb tau lees paub rau cov rwb thaiv tsev thermal yog nylon 66 (PA66 GF25) nrog 25% iav fiber ntau.

Lub linear thermal expansion coefficient ntawm PA66 yog ze heev rau ntawm aluminium alloy. Qhov no txhais tau hais tias kev nthuav dav thiab kev cog lus ntawm cov rwb thaiv tsev sawb thiab cov khoom siv aluminium yog synchronized thaum lub caij ntuj sov kub ntawm lub caij ntuj sov thiab lub iab txias ntawm lub caij ntuj no hmo ntuj. Vim yog qhov sib npaug ntawm qhov sib npaug, tsis muaj kev ntxhov siab shear yog tsim los ntawm cov ntsiab lus sib txuas vim rov ua thermal expansion thiab contraction. Qhov no ua kom ntseeg tau tias cov txheej txheem thermal tawg yuav tsis xoob, tawg, lossis ua rau lub qhov rooj deformation rau 30-50 xyoo, ua rau tsis ncaj nce lub neej ntawm lub qhov rooj.

3.2 Nthuav cov phom sij ntawm PVC Thermal rwb thaiv tsev strips

 

Qee qhov qis- nqi aluminium qhov rooj ntawm lub khw siv PVC thermal rwb thaiv tsev strips. Txawm li cas los xij, PVC muaj lub zog tsawg, tsis muaj cua sov tsis zoo, thiab qhov sib txawv thermal expansion coefficient piv rau txhuas. Tom qab ob peb lub voj voog ntawm cua sov thiab cua txias, PVC strips ua nkig thiab ntsws, ua rau cov thav duab aluminium kom loosen thiab txawm poob nws thermal rwb thaiv tsev muaj nuj nqi. Lub neej ntawm PVC thermal rwb thaiv tsev strips feem ntau tsuas yog 5-10 xyoo; ib zaug nws ua tsis tiav, cov qauv thiab dej tsis sib haum ntawm tag nrho lub qhov rooj raug cuam tshuam.

 

SGL pom zoo tias thaum yuav aluminium alloy qhov rooj, koj yuav tsum paub meej tias cov rwb thaiv tsev thermal yog ua los ntawm PA66. Qhov no yog ib qho tseem ceeb heev kom paub meej tias lub qhov rooj qauv kav ntev tshaj 40 xyoo.

Thaum aluminium thav duab tuaj yeem kav ntev li ib nrab xyoo, lub qhov rooj yog qhov system. Cov khoom siv kho vajtse thiab cov hlua khi yog qhov ceev tshaj plaws - hnav qhov chaw ntawm lub cev no, thiab lawv lub neej feem ntau txiav txim siab lub sijhawm "kev tu- dawb" ntawm lub qhov rooj.

4.1 Sealing Sawb

Lub foob ntawm lub qhov rooj thiab lub qhov rooj ncej txiav txim seb puas muaj huab cua to, dej to, thiab suab rwb thaiv tsev. SGL siv EPDM (ethylene propylene diene monomer) roj hmab. High- zoo EPDM sealing strips muaj UV tiv taus thiab ozone tsis kam, thiab lawv lub neej ntev yog 8 npaug ntawm PVC strips, ncav cuag 20-40 xyoo. Lawv kuj muaj zoo elasticity, rov qab lawv cov qub zoo tom qab lub sij hawm ntev compression, tswj sealing siab.

4.2 Kho vajtse

Cov khoom siv kho vajtse siv los ntawm SGL yog Guitto, lub tuam txhab tshwj xeeb hauv siab -kawg qhov rooj thiab qhov rais kho vajtse. Headquartered nyob rau hauv Nanhai District, Foshan City, Guangdong Province, nws cov lag luam tseem ceeb yog muab cov neeg muas zaub nrog tus nqi - zoo tag nrho cov kev daws teeb meem rau lub qhov rooj thiab qhov rais hardware. Guitto ua raws li Danish craftsmanship thiab cov qauv zoo thiab yog ib tug nyiam tsum ntawm siab - zoo qhov rooj thiab qhov rais hardware systems.

 

Guitto's hinges, xauv, pulleys, thiab lwm yam khoom yog tag nrho ua los ntawm cov qib siab - stainless hlau zoo, uas tuaj yeem hloov tau zoo rau ntau qhov chaw, xws li cov ntug hiav txwv dej thiab thaj chaw txias. Tom qab 20,000 lub voj voog ntawm kev sim siv, cov khoom siv kho vajtse no tseem ua haujlwm li qub. Raws li 5 qhov qhib thiab kaw ib hnub hauv ib tsev neeg ib txwm, 20,000 lub voj voog yog sib npaug rau 11 xyoo ntawm kev ua haujlwm. Nyob rau hauv qhov tseeb, tsuav yog lawv tsis overloaded thiab tsis tu ncua lubricated, siab - kho vajtse zoo yuav kav ntev li 20-30 xyoo.

Dab tsi yog qhov kev cia siab lifespan ntawm aluminium alloy qhov rooj?

• 30-40 xyoo (tus qauv teeb tsa, kev siv ib txwm).
• 50-60 xyoo los yog ntau tshaj (sab saum toj-tier configuration: 6063-T6 + PVDF/AA25 + EPDM + stainless hlau hardware, nrog rau kev saib xyuas tsis tu ncua).

Piv nrog rau yooj yim aging uPVC thiab yooj yim rotting ntoo, aluminium alloy qhov rooj yog tam sim no lub feem ntau ruaj, yig, thiab ib puag ncig tus phooj ywg ntev -lub sij hawm peev kev daws teeb meem ntawm lub tsev lag luam. Lawv "lifespan" feem ntau tsis txiav txim siab los ntawm cov khoom siv nws tus kheej, tab sis los ntawm koj li cas, raws li cov neeg siv khoom, xaiv qhov kev teeb tsa thiab seb koj kho nws li cas.

SGL cov lus qhia kawg rau cov neeg yuav khoom: Yog tias koj xav kom koj lub qhov rooj kav ntev li ib nrab xyoo:
